Eureka, CA, February 24, 2009 - I was perusing KIEM-TV’s website earlier tonight when I ran across an interesting link to their policy on granting waivers to satellite television viewers (specifically DirecTV viewers) for reception of network programming at http://kiem-tv.com/waiver.html.

Basically, their policy is the same as the other local commercial television broadcasters in the area. If you need a waiver… you’re screwed. None of the local TV broadcasters will sign waivers for anyone, regardless of how bad their TV reception is.

KIEM specifically cites the FCC’s regulations about not needing to grant waivers in what are defined in Predicted Grade B Contour Areas. These are areas where anyone should supposedly be able to receive a TV signal, granted that they use an outdoor antenna placed 30′ above the ground. On it’s face, this rule actually sounds quite reasonable. Neither the FCC nor TV stations ever intended that viewers ever be able to view television programming from local broadcasters by using something as simple as a pair of “rabbit ears”, sitting on top of a television set.

Indeed, when early TV first began, there was a booming business in (outdoor) TV antenna installation. Over the years, the public has come to expect TV reception to be easy and hassle-free though. They don’t want unsightly antennas, ugly cables or silly wires cluttering their homes. This points to more of a need for a national attitude adjustment than it does a technical solution. If reception this simple is what Americans are waiting for, they are going to be sorely disappointed. It just isn’t going to happen. Not in our lifetimes, anyway. Those who want to receive a good over-the-air TV signal should be prepared to install a good antenna! It’s not politics; it’s simple physics, so get over it.

Back to the whole “Predicted Grade B Contour Area” issue though. As I stated, on it’s face, this policy seems like a logical and reasonable one. Unfortunately, the sad fact is, the technology used to create maps that show areas which fall into these contours is woefully inadequate. The standards that engineers use to create these maps has not really changed much in the past 100 years. Although computers are now used for map creation, they simply speed-up the same process that would normally take an engineer much longer to accomplish by hand.

With the exception of some very basic terrain calculations, very little real-world data is taken into consideration with these charts. Calculations are measured as if the earth existed inside a vacuum where no atmosphere, weather, earth curvature, man-made obstructions, vegetation, RF interference, multipath, solar flares or other factors ever enter into reality. To add insult to injury, these maps only show where it is allegedly technically possible to obtain “a signal”. This does NOT mean a watchable picture, or any type of signal that could reliably be used for the viewing of television pictures. It just requires that “a signal” of extremely minimal quality exists.

In fact, the FCC specifically defines the type of quality expected in a Predicted Grade B Contour Area. In one of its notices, it states: “…the values chosen for Grade B signal intensity account for location and time variability factors and predict that at least 50 percent of the locations along the Grade B contour will receive an acceptable picture 90 percent of the time. In this case, acceptable picture was considered to be TASO Level 3, defined as (passable) – The picture is of acceptable quality. Interference is not objectionable.”

Human Translation: In most areas, at best, your odds of receiving a “passable” signal by FCC standards (which most of us would probably define as a “really crappy picture”) – using an outdoor antenna placed on a 30′ mast, are 50/50… 90% of the time. Of course, these are only predictions, based upon completely inadequate data that is rarely accurate in real-world situations. Such an antenna set-up will likely set you back over $100, should probably be professionally installed and should have NO objects of ANY kind between itself and the broadcast station’s transmitting antenna. In other words, line-of-sight. Depending upon where you live, installation of a mast that extends 30′ from the top of your roof (which, for a two-story house, would be about 50′ off the ground) may also require you to obtain a building permit from your city or county, which could take months and cost hundreds if not thousands of dollars in building permits and increased property taxes. How many people can really afford that?

KIEM’s Grade B Contour Area is similar to that of other, local TV broadcasters (although, I believe that it might actually be outdated, and only show coverage areas for their older, and stronger, analog signal). Basically, if you live ANYWHERE in Humboldt, Del Norte or most of Trinity County, you are in a Grade B Contour area, according to the map. Those of us who have actually tried obtaining over-the-air TV reception in places like Trinity County will find maps such as those provided by KIEM-TV to be laughable, at best. With the new transition to DTV, the odds of obtaining a digital signal that could result in the reception of ANY type of TV picture AT ALL is diminished for the vast majority of viewers in outlying areas.

WHO’S TO BLAME FOR BAD RECEPTION?

It seems that everyone wants to point fingers in the broadcast industry. For it’s part, KIEM-TV seems to blame DirecTV for everything (strangely, they make no mention of DISH Network by name). Their position seems to be that since DirecTV promised their customers at one time that they would add local TV stations in every single U.S. market to their programming line-up, that they should be held to their word. Sounds fair enough, as DirecTV did, indeed backpedal on their promises. However, while KIEM makes it sound as if it they are blaming DirecTV out of their concern for viewers, that is almost certainly not the real reason for the finger pointing.

In reality, the main motivation behind KIEM’s attack of DirecTV is most likely due to the fact that without DirecTV footing the bill to uplink KIEM’s TV signal to their satellite, the station is not only losing potential viewers (which equals ratings, which equals money) but much more importantly, not receiving a monthly royalty check from the satellite TV provider in exchange for rebroadcast rights. KIEM gets a fat check from Suddenlink for rebroadcast rights to their subscribers each month, but not from DirecTV or DISH. Unfortunately, current FCC rules actually encourage local TV broadcasters to limit the availability of their over-the-air signals, since those receiving their programming via TV antennas pay broadcasters nothing. Those who receive their network programming via satellite, Suddenlink or other cable television companies end up having to pay broadcasters for their programming (albeit, indirectly) through increased subscription rates.

For it’s part, DirecTV aand DISH don’t seem to have anyone to blame, at least officially. DirecTV in particular, just blows-off it’s own customers by suggesting that local TV stations in Humboldt County will be included in the programming lineup “some day”. Whether they are just playing stupid, or there are employees at the company dumb enough to actually believe this, is questionable. Call a DirecTV customer service rep, and it’s quite possible that they will make local TV broadcasters out to be the bad guys, saying that their refusal to grant local waivers is unfair to TV viewers (which it certainly is). They will not acknowledge the fact that their own motivation NOT to carry these stations is due to the fact that it costs them more money to set-up and maintain the equipment alone than they could ever hope to recoup through subscription fees to the limited number of homes here.

So, who’s to REALLY blame? In my opinion, the real blame rests with the Federal Communications Commission. If it were not for the FCC’s ridiculous rules requiring local TV broadcasters to only provide a “Predicted Grade B Contour Area” (B should stand for Barely any signal at all) quality signal to local viewers without fearing competition from out-of-market TV stations carried by satellite TV providers, we simply would not be in this mess. If local TV broadcasters were held to a standard that made them provide an actual WATCHABLE TV signal in these areas, it would encourage them to provide their viewers with reliable access to programming, out of fear that they would be able to get it from elsewhere. This could be achieved through several means, most notably being the increased use of translators or requests to broadcast using increased power levels with radiation patterns that optimize reception in rural areas. Although the FCC has examined these issues in recent years, nothing positive has come out of it thus far. As it is, the transition to DTV has led to over-the-air TV signals being available to far fewer Americans than before, which is forcing more and more people to switch to cable or satellite TV just to receive programming from their local TV stations.

Just count the number of houses on your block with outdoor, over-the-air TV antennas as opposed to dishes or drops from the local cable company to confirm this fact. Even in areas that SHOULD have good local TV reception, most are forced to turn to cable or satellite for local or broadcast network programming.

ALL CABLE CUSTOMERS PAY EXTRA FEES FOR “FREE” LOCAL CHANNELS

This also applies to anyone who is able to receive local, commercial TV broadcasts on satellite services such as DirecTV or DISH Network in areas where local stations are available.

If you think that getting local channels on your cable system is free, you’re just kidding yourself. All cable TV providers such as Suddenlink have to pay commercial broadcasters to carry their signal under federal law. Of course, these added costs are going to be passed on to the consumer. You don’t think that the cable company is going to pay these extra fees out of their own pockets, do you?

The FCC states as much in their FCC Cable Television Fact Sheet. Just to make it as clear as possible, here is a direct quote from the FCC’s own literature:

Q: Will my cable bill increase as a result of retransmission consent agreements?

A: In return for allowing a cable system to carry its signal, a television station may require the payment of a fee or other consideration (for instance, carriage of another programming service or advertising time). Any new or additional costs incurred as a result of retransmission consent agreements may be passed through to cable subscribers.

The FCC needs to reconsider the current scheme in place that allows local TV stations to charge cable and satellite TV providers for rebroadcast rights to their “free” signals. After all, in theory, all that the cable and satellite broadcasters are doing is extending the reach of a TV station’s broadcast area and potential viewership, which should bring in more viewers, which should make them more money from advertisements. At least, that’s how it SHOULD work.

Unfortunately, the reality of the situation is that TV broadcasters see cable and satellite providers as alternative streams of income, and are positioning themselves to be more like pay cable channels than over-the-air broadcasters. Local TV stations used to rely upon the popularity of their programming in order to attract more viewers, which would generate better ratings, which would lead to increased profits. Under the current scheme, broadcasters don’t need ANYONE watching their programming in order to make money from cable and satellite TV providers. Rather than the public deciding through ratings what programming should stay on the air, this scheme encourages broadcasters to provide viewers with the least expensive programming they can find. Perhaps that’s why we only have a single local TV station in Humboldt County that bothers to broadcast local news (which is very expensive to produce) anymore.

The bottom line is, letting TV broadcasters charge rebroadcast fees to cable and satellite providers for their “free” signals only encourages these broadcasters to limit the quality and availability of local broadcast signals, hopefully forcing most viewers to resort to subscribing to cable or satellite, where they make much more money. This obviously runs contrary to their responsibility to serve the public interest, which they are obligated to do under federal law. This obligation results from the fact that they are using segments of the frequency spectrum, which are a limited, public resource.

Unfortunately, the FCC has all but forgotten that broadcasters are supposed to serve the public interest. Successive presidential administrations have made the Federal Communications Commission much more of a political policy tool than the enforcement and regulation entity they once used to be. Most major decisions at the agency these days are politically motivated, rather than being made on technical or legal grounds. United States courts have increasingly had to step-in in recent years to curb abuses of power at the FCC and force them to vacate their own rules, finding them to be unconstitutional. When it comes to the point where private citizens have to take federal agencies to court in order to prove that they are knowingly operating in direct violation of the United States Constitution, you really have to question their ability to act as an unbiased government regulatory agency.

WHY YOUR TV RECEPTION SUCKS… CONCLUSION

What it all boils down to is the fact that “free TV” isn’t really free for most of us anymore, especially for those caught in the middle of a pissing contest between the satellite and broadcast television industries. Unless Congress decides to step-in and force satellite TV providers like DirecTV to rebroadcast ALL local TV stations in the United States (which would result in skyrocketing satellite TV subscription prices, no pun intended), you can bet that those who live in areas with fringe reception will continue to be treated as second class citizens by both local broadcasters as well as satellite TV providers, and that the quality of television programming itself will continue to decline.

Apparently, the Federal Communications Commission received a number of complaints about the cable television provider when it decided to switch certain analog channels on its cable system to digital this past month. The FCC’s Enforcement Bureau launched an investigation into the matter and ordered Suddenlink to answer a number of questions and provide documentation on the matter via an official Letter of Inquiry (LOI). It gave Suddenlink two weeks to respond.

Rather than comply with the LOI, or even attempt to comply, some bonehead acting on behalf of the company decided to send back a letter questioning the FCC’s authority on the matter and actually accused the Commission of breaking federal law by not complying with the federal “Paperwork Reduction Act”, among other things. They also questioned the FCC’s authority to demand such information within two weeks, which they deemed not enough time. They never suggested exactly how much time they thought would be more appropriate. Three weeks, perhaps?

Anyone who has ever dealt with the Federal Communications Commission is well-aware that anyone falling under their authority (Suddenlink definitely does) who is stupid enough to question their judgment or jurisdiction is just asking for trouble. To put it mildly, the FCC has no sense of humor when it comes to these matters. The fact that someone this incompetent at Suddenlink has been put in a position responsible enough to respond to official inquiries from the U.S. Government simply boggles my mind. I am used to seeing these kinds of responses from dimwitted CEO’s of telecommunications resellers, but to see this coming from a licensed, facilities-based carrier is just plain scary. If the company was publicly-traded, I would advise dumping their stock immediately, as corporate incompetence such as this rarely results in a solid bottom line. As it is, I’m just lucky that I don’t have to suffer through being a Suddenlink customer.

In any event, the results were completely predictable. Suddenlink was issued an NAL, or Notice of Apparent Liability, for $25,000 for its part in thwarting the FCC’s investigation. An NAL is sort of like a speeding ticket. The company has the right to a hearing, but it’s pretty much just a kangaroo court that is run by the same people who ordered the NAL in the first place. You can’t fight city hall. Duh!

This may not be the end of the matter, by a long stretch. If Suddenlink continues to stonewall the FCC, the Commission will simply keep piling-on the fines. In theory, they could actually revoke Suddenlink’s ability to offer its services. I have to believe that there must be someone with an ounce of sanity at the company who will step-in before it comes to that though. Until then, Suddenlink customers will likely look forward to higher cable bills as a result of the NAL. After all, someone has to pay for the $25,000 penalty, and it quite certainly isn’t going to come out of the pockets of Suddenlink executives.

As most of us know by now, there are no more coupons left. At this point, all one can do is get on a waiting list with more than 1 million people ahead of you. Unless Congress decides to provide additional funding (not likely), most people on the waiting list will be waiting forever. I think it’s safe to say at this point that anyone needing a DTV converter box is on their own. Unless you already have an un-expired coupon already, you are most likely out of luck.

The good news is, as the current supply of non digital televisions slowly work their way to the junk piles to be replaced by HDTV ready TV sets, you will eventually see the existing converter boxes make their way to yard sales, flea markets and (of course) eBay. Being the transitional technology it is, DTV converter boxes will eventually end-up becoming an obsolete piece of equipment that almost no one will need to own. So, if you don’t mind waiting awhile, you will eventually be able to buy these things for next to nothing.

For those of you who would like some “face time” with a representative of the FCC, there will be a digital conversion workshop at the offices of the Area 1 Agency on Aging in Eureka, CA, on Thursday, January 15, 2009 at 11 a.m. The A1AA is located at 434 Seventh Street.

The bottom line is, TV stations like KIEM-TV probably can’t justify the cost of spending tens of thousands of dollars to upgrade small translators like those in Orleans, which reach only a handful of viewers. While the FCC pedals its “No TV left behind” rhetoric to the public, the economics of the situation does not bode well for either broadcasters or rural TV viewers. While financial aid has been made available to the public via TV converter coupons, TV stations in small markets and those serving rural communities via translators are getting no such help from the federal government.

In light of recent events with the economy, the federal government’s mandate that TV stations cease broadcasting their analog signals in February is dripping with irony. On one hand you have the federal government handing over hundreds of billions of dollars to banks and automakers with few or no strings attached so that they may continue selling Americans overpriced cars and high-interest loans. On the other hand, we have the Federal Communications Commission forcing for-profit businesses to cease offering a free service to the public that actually pays for itself. Here’s the real punchline though… part of the motivation for forcing broadcasters to cease transmitting analog signals in the VHF band is so that the government can turn around and auction off those same frequencies for billions of dollars. Much of that money may end up being spent on bailing out banks and automakers.

Obviously, the FCC could not have foreseen the current economic crisis and the resulting overwhelming lack of enthusiasm that consumers are currently showing when it comes to paying for upgrades to their TV sets. The unfolding scandals plaguing the FCC are only likely to grow worse when thousands of Americans eventually lose access to television programming in February though.

The website seems to have a fairly large selection of DTV converters, as well as a handful of HDTV-ready antennas. Shipping looks to be a flat $9.95 per order. The cheapest converter they currently have available is $52.95. When you add-in shipping charges, that would make the cheapest digital television converter you can buy from them come out to about $23 after using your coupon. Depending upon where you live, the $9.95 price for shipping can be balanced against the fact that they do not charge sales taxes in most states. In high tax states like California, ordering two converters at a time from them would be only slightly more expensive than if you had bought the units (at the same price) locally and had to pay the sales taxes.

One potential problem that you might have ordering from this site is one that pretty much all retailers have in common these days. Many of the models listed are out of stock, and quantities are limited. Also limited are the number of DTV converters that provide analog pass-through capabilities. As we have stated in previous articles, this is a key feature that most DTV converters are currently missing. Not having this feature will leave you unable to view channels that are still broadcasting in analog. Quite a number of translators and LPTV stations in the local area are currently in analog and will STAY in analog for some time to come. These stations are exempt from FCC rules mandating the switch to digital television. Almost half of the TV stations in Humboldt County are classified as LPTV, or low-power television. The percentage is much higher if you count the numerous low power translators scattered throughout Humboldt, Trinity, Mendocino and Del Norte Counties in Northern California.

Needless to say, we would recommend holding off on ordering a CECB converter box until you can get one with analog pass-through capabilities. You may have to check websites and retailers regularly to find any in stock, but it is definitely worth the wait in areas like Humboldt County, where there are so many stations continuing to broadcast in analog.

Another good place to look online for DTV converters is SolidSignal.Com. We have always had excellent service when ordering from this company and we highly recommend them. In addition to selling the CECB digital to analog converters, they also sell a large selection of DTV-ready antennas, cabling and accessories. You can also find gear for DirecTV, Dish Network and other satellite TV equipment as well. SolidSignal.Com is able to process government coupons for DTV converters now, so you should be able to order these products online and still get your $40 discount without any hassles.

As always, if you haven’t applied for your free government coupons yet, be sure to do so. You can apply directly online through the government’s website at DTV2009.GOV .

AACS – Advanced Access Control System. A computer specification for guarding next-generation optical-media content created by the film, electronics, and software industries.

AC-3 – (see Dolby Digital 5.1)

Aliasing – Jaggedness that appears at diagonal edges of objects in a pixel or raster image. De-aliasing (anti-aliasing) is a smoothing of the jagged edges by blending adjacent pixels slightly.

Artifact – A flaw in an image caused by the way the data is processed. Interference and noise are not usually called artifacts. So artifacts are in a sense predictable.

Aspect ratio - The ratio of screen width to screen height. For TVs it is either 4:3 (1.33:1) or 16:9 (1.78:1). Theater film uses many different aspect ratios, some as high as 2.5:1.

ATSC – (Advanced Television System Committee technical standard) This is the name of the technology used by terrestrial digital TV stations in the U.S.

Blocking – Macro-blocking An over-compression of the image that makes the block edges slightly noticeable. This “checkerboarding” is subtle and usually momentary. Some causes are:

1. Software bugs in the MPEG encoder.
2. The neBlockstwork allocating too little bandwidth to the broadcast.
3. The picture being portrayed is just changing too fast.

Blocks - Macro-blocks MPEG-2 divides the screen into small square regions called blocks and uses a mathematical process to compress the data for each block. Macro-blocks are a small group of blocks. See What exactly is ATSC? .

BNC connectors – These common RF connectors are sometimes found on VGA cables in place of a VGA connector. They employ a quarter-turn twist-lock mechanism.

Bob and Weave – Two processes for de-interlacing (converting interlaced video into progressive scan). Weave refers to combining successive fields. Also called interfield, this method preserves the original resolution. Bob refers to up-converting a field into a frame, in effect creating new lines by averaging the adjacent lines above and below. Also called intrafield, this method causes a loss of resolution but never causes motion artifacts. See also Motion Adaptive De-interlacing.

Breakup – Also called dropouts, block errors, or macro-block errors, these are gross errors in the picture caused by reception errors that result from interference and signal noise. Both audio and video are affected, with video distortions about five times as prevalent as audio dropouts. This ratio never seems to change. If the ratio is anything else then the cause is a network problem, not a reception error. The shortest-lasting breakups just cause a few macro-blocks to be obviously wrong, while more severe errors cause major parts of the screen to be left un-updated for a time, and possibly the whole image to freeze. Green shows up a lot.

Cable card - The Cable Card is the mechanism the industry has adopted to prevent the piracy of cable services. Nearly all cable channels are encrypted, the main exception being local stations. The cable card contains the keys to unlock encryption.

If you want the simplicity that comes with the cable receiver being integrated with the TV then you should buy a TV with a cable card slot. However if you like TiVo then you would instead get a DVR, which will have its own cable card slot. The cable card is supplied by the cable company. The card is a special purpose PCMCIA card (like used in many computers).

The present cable card system for DTV is called CableCARD 1.0. There are two types of cards: SCards (single stream) and MCards (multiple stream). MCards are used when a DVR can record multiple programs simultaneously.

CableCARD 1.0 – lacks two-way features and cannot be used for ordering pay-per-view, interactive guide, and other two-way features. Millions of cable card slots in TVs already sold are going unused. Reasons include: 1. The viewer uses satellite. 2. The viewer doesn’t want subscription channels. 3. The user wants two-way features and so has to use a cable box. Some TV makers are reducing the number of sets they sell having cable card slots, but they say they will increase the number when two-way is possible. Two-way is not available because the technical standard is not yet established. (The CEA and NCTA are fighting each other and the FCC has been a timid referee.) Present DTV systems with CableCARD 1.0 are labeled DCR (Digital Cable Ready). Future DTVs will likely be labeled iDCR (Interactive Digital Cable Ready).

Warning: The term CableCARD 2.0 has two conflicting definitions. 1. CableCARD 2.0 was first used to refer to the next generation of cable services that included two-way features. 2. SCards were introduced first. Later, when MCards were introduced they were commonly referred to as CableCARD 2.0.

C-band / Ku-band – 1. a range of RF spectrum. C-band is approximately 4 GHz. Ku-band is app. 12 GHz. 2. Geo-stationary satellites the networks use to acquire and distribute programming to affiliates and cable TV companies. These satellites use C-band and Ku-band frequencies. 3. a consumer service that uses the satellites the networks originally set up for themselves. An 8-foot steerable dish is required. Some channels are free. Others are available by subscription. The digital channel subscription service is called 4DTV.

CEC - (Consumer Electronics Control) This feature allows units to control each other. The commands tend to be the same as the buttons of an infrared remote control, so fewer remotes are necessary. The implementation is a single-wire bus that is a “party line” connecting to all units. The HDMI cable carries this line.

CECB – Coupon Eligible Converter Box. An analog-to-digital DTV converter box that has been approved by the federal government for use with its $40 discount coupons.  Coupons are available from the U.S. federal government at http://www.dtv2009.gov .

COFDM - modulation technique. This technical standard has been used in Europe and other places for digital TV. 8VSB is used in the U.S.

Color temperature – This describes how white is displayed. Low temperature means slightly reddish, while high temperature means slightly bluish. Standard NTSC white corresponds to the color a glowing hot object would be at 6500° K

Comb filter – A circuit in NTSC sets that separates the color information from the brightness information.

Component video - This 3-wire convention was created for connecting DVD players to TVs or monitors. It avoids downgrading the signal to NTSC. The signals may be RGB or YPrPb. Some HD STBs have only component video output.

Composite video - This 1-wire standard contains all video information: intensity, color, and sync. The encoding is the same as NTSC, and thus has the “overlapping sideband” problem which sometimes causes wrong colors to appear.

Convergence – An adjustment that must be made occasionally to CRT sets. This adjustment makes the three colors coincide perfectly.

DBS – (direct broadcast satellites) These satellites are powerful enough to be received by an 18 inch dish. They use Ku-band and Ka-band frequencies. Companies that provide DBS services to consumers in the U.S. are DirecTV and Dish Network. Canadian DBS providers are Star Choice and Bell ExpressVu. Also called DSS. They typically broadcast in some type of digital format that is encrypted at the uplink and decoded by the receivers of authorized subscribers.

D-ILA – (Direct-drive Image Light Amplifier) (see LCOS)

DirecTV – One of the two major providers of DBS programming in the United States.

Dish Network - One of the two major providers of DBS programming in the United States.

DLP - (digital light processor). A technology for video projection, also call DMD (Digital Micro-mirror Device). It is a large chip with about a million tiny mirrors on its surface. The chip can tilt each mirror to vary the amount of light reflected off of it.

Dolby Digital 2.0 – This is a two channel (stereo or Pro Logic) version of Dolby Digital. It is often used by DBS systems.

Dolby Digital 5.1 – Also known as AC-3, it provides 6 channels of sound: left, center, right, left rear, right rear, and sub-woofer. It is also called “5.1 channels” since the 6th channel has reduced bandwidth. Dolby Digital 5.1 is the audio standard for all U.S. digital TV stations, most DVDs, some DBS programs, and many theaters.

Dolby Pro Logic Surround – This is a 4-channel analog system. During recording, the 4 channels are “folded” into 2 stereo channels. If played back without a Pro Logic decoder, it sounds like normal stereo. This format is becoming obsolete.

Dot Crawl – a common flaw in NTSC images caused by the “overlapping sidebands” problem. It consists of animated checkerboard patterns which appear along vertical color transitions.

DTCP - (Digital Transmission Content Protection) This is an encryption standard for IEEE 1394 that prevents the copying of first-run movies and pay-per-view events. DTCP is also called 5C Copy protection (in reference to the ‘five companies’ that license it).

DTS - An alternative to Dolby Digital. ATSC does not use DTS but some DVDs do. Most audio receivers that work with Dolby Digital also handle DTS.

DTV – (digital TV). Examples of DTV are DBS satellite services, digital cable TV services, and ATSC digital TV (over-the-air, broadcast) stations.

DTVLink – This logo is on equipment that has IEEE 1394 and DTCP.

DVB – (Digital Video Broadcasting) An alternative to ATSC used in most of the world outside the U.S. It has three different standards:

· DVB-T is for terrestrial (OTA) broadcasts.

· DVB-S is for satellite broadcasts.

· DVB-C is for cable broadcasts.

DVI - (Digital Visual Interface) This connector conveys HDTV image scanning signals in binary data form. The data rate is very high (1.65 Gb/s). Binary data is preferred by monitors that are not CRTs. DVI comes with a decryption option called HDCP which will decode encrypted programs such as first-run movies.

EDTV – (enhanced definition TV) Essentially DVD quality, it is a small step up from NTSC. An EDTV will convert all 18 ATSC formats to 480p.

FCC – (Federal Communications Commission) This is a Federal agency responsible for regulating radio wave usage and some other media. The FCC answers to Congress and also implements international radio standards.

Fire-wire – (see IEEE 1394)

First-surface mirror – Normal mirrors have the silvering on the back surface of the glass. First surface mirrors have it on the front. Cleaning a first-surface mirror must be done very carefully.

Flicker (or Twitter) - Flicker is a pulsating of the image, a flaw most noticeable in images drawn only 24 or 30 times per second. Flicker is usually only noticeable in bright whites.

FM – Frequency Modulation. An analog method of modulating a carrier wave (frequency) with an audio or video signal. Primarily used for transmission of audio and music.

FTA – “Free To Air” or “Free To All”. This is a digital satellite technology employing MPEG-2, but it is not compatible with DBS systems (Dish or DirecTV) or with Motorola Digicipher II (C-band 4DTV) and it doesn’t have a provision for encryption. At the present time the only high definition stations on FTA are PBS, Voom, The Outdoor Channel, and Movie Central. Lyngsat.com lists all the stations. Skyvision.com, FTAsatellite.com, and others sell receivers. The frequencies used are Ku-band and C-band. FTA’s forte is that it is cheap and very international. FTA is heavily used outside the U.S. FTA started becoming popular in the U.S. about 2002 among experimenters and immigrants. In the opinion of some people the rise of FTA is a mistake and HDTV might eventually kill it. It might survive in the U.S. market because of a need for an unregulated domain for international stations.

GLV – (Grating Light Valve) This is another contender to replace CRTs in projection TVs.

HAVi – (Home Audio Video Interoperability) This is a standard for 1394 bus audio and video devices. It is software that is required for the units to talk to each other. HAVi allows plug-and-play recognition of devices, interoperability, and brand independence.

HDCP – (High-bandwidth Digital Content Protection) This is a DVI decryption option. It will decode encrypted programs such as first-run movies. (It’s real function is to prevent unauthorized copying of programs.)

HD- Capable TV A standard definition set with a digital tuner. (This term was probably invented to confuse people.)

HD- Ready TV An HDTV monitor or TV that lacks a digital tuner.

HDMI – (High-Definition Multimedia Interface) This miniature connector is intended to replace DVI. It is backward compatible with DVI, and an adapter will connect it to a DVI unit. It has 19 pins and carries DVI plus digital audio. It also has a reverse data line (DDC) that allows the STB to sense the monitor’s state and native formats, and a control line (CEC) for system level control.

HDTV – (High Definition TV) A TV that displays 1280×720 pixels or better.

IEEE 1394 - Also called Firewire or iLink. Originally a serial bus for PCs, 1394 may or may not become the interconnection standard for DTV products. It is competing with HDMI. IEEE 1394 is a spec for a hardware interconnect plus a software shell. But additional software, such as HAVi, is required for connected units to actually talk to each other.

i.link – (see IEEE 1394) Sometimes referred to as “firewire”.

Interlaced scan – Historically, TV CRTs are interlaced, while computer CRTs are not. Interlaced means that the electron beam skips every other horizontal line, filling in the missing lines on the next pass. A frame is composed of 2 fields. One field is all of the odd numbered lines, and the other field is all of the even numbered lines.

Jack – A female connector, usually for audio or video connections.

Ka band – A range of RF spectrum centered around 30 Gigahertz. Historically never used, DirecTV and Dish Network are starting to launch satellites that use these frequencies. (The name comes from “above K band”. K band is a long established military band.)

Ku band – A range of RF spectrum centered around 12 Gigahertz. These are the principal frequencies used by DirecTV and Dish Network, although DirecTV will probably some day move entirely to Ka band. (The name comes from “under K band”.)

LCD – (Liquid Crystal Display) LCD is the most common flat panel display technology.

LCOS – (Liquid Crystal On Silicon) This is an LCD-like projection technology.

LFE - (Low Frequency Effects) Sub-woofer. The 6th channel in a 5.1 channel system.

Line Doublers – This device converts NTSC or 480i into 480p. Line doublers with motion-adaptive processing can to an extent turn a 30 frames/sec image into a 60 frames/sec image, thus removing some of the jerkiness and blurriness associated with motion.

LNA – Low Noise Amplifier. These were used in C-Band TVRO systems prior to the invention of the LNB. The only difference between an LNA and LNB is that the LNB downconverts the original satellite transmission frequency to a lower frequency for transmission through coaxial cable. There is lower loss in coaxial cable at these frequencies, making LNBs more efficient than LNAs.

LNB – (Low Noise Block converter) An LNB can be found at the focus point of a dish antenna. It is a low noise amplifier that also converts the signal to a lower frequency. (The original higher frequency would not travel very far in ordinary coaxial cable.)

Mosquitoes Fuzzy dots that can appear near sharp edges in MPEG and JPEG images, possibly looking like a swarm of mosquitoes. These artifacts are caused by over-compression or over-enhancement of edges.

Motion Adaptive De-interlacing The image is divided into regions where there is motion and where there is none. Areas of the image without motion are de-interlaced using “weave”, and areas with motion are de-interlaced using “bob”. See Bob and Weave.

MPEG-2 (Motion Picture Experts Group technical standard 2) This is a widely used standard for digital encoding of motion pictures. It typically achieves a 50 to 1 compression of data. It achieves this mainly by not retransmitting areas of the screen that have not changed since the previous frame.

MTS – (Multi-channel Television Sound) This refers to an analog NTSC TV equipped with stereo and SAP (separate audio program) features.

Multipoint convergence – Projection TVs with 3 CRTs require periodic adjustment to keep the 3 images perfectly aligned. Typically this is a simple 5 minute procedure the consumer must do every month or so.

Multi-path interference – Some neighborhoods are plagued with this problem: The signal finds more than one path to the antenna. Multi-path results from diffraction around the sides of hills and buildings. For NTSC sets this will result in ghosts: multiple images shifted laterally. For DTVs the result can be an unusable signal, even though it may be strong. The solutions are moving the antenna or selecting a very directional antenna. Newer generations of DTV receivers are better able to cope with multi-path.

Must-Carry – This refers to the legal obligation of cable companies to carry analog or digital signals of over-the-air local broadcasters.

Native format – Most DTVs will convert the 18 ATSC formats into 1 or 2 formats and will draw only those. For these sets, the ‘native’ format is 1. the formats the set will draw or 2. the original format. (These are contradictory definitions, but they reflect current practice. 1 is probably the preferred meaning.)

NTSC – (National Television System Committee technical standard) This is analog TV invented in 1946. NTSC has 525 lines (483 visible) interlaced, 60 fields per second. This (analog) standard is in use in North America, Japan, South Korea, Burma, Taiwan, the Philippines, and much of South America.

OAR – (original aspect ratio) Also called Letterbox format, OAR means that none of the image is clipped or squeezed. Unused parts of the screen are usually black.

OLED – (Organic LED) A new display technology. Somewhat resembling plasma, it uses organic Light Emitting Diodes.

OTA – (over the air) Analog or digital terrestial broadcasting of a television signal. Typically used to refer to broadcast television stations in North America.

Over-scan/Under-scan – Computer CRT monitors under-scan, which means they leave a thin black border around the image. TVs over-scan, which means a small part of the image perimeter is lost. (Digital displays don’t necessarily do either.)

PAL - (Phase Altering Line standard) This alternative to NTSC has 625 lines, interlaced, 50 fields per second. It is used in most of Europe, Asia (except USSR), Africa, and Australia, and parts of South America.

Pan-and-scan – A method of broadcasting a wide screen film on a 4:3 channel. Most of the time just the center of the image is shown. (The right and left edges are clipped off.)

PCM – (Pulse Code Modulation) or L-PCM (Linear PCM) This 2-channel digital audio standard is simpler than Dolby Digital.

Pixilation - What you see when you sit too close. (You see individual pixels.)

Plug – A male connector.

PrimeStar – An early attempt by Cox Cable to compete in the DBS market. It ran this KU band system in the United States for several years before folding, opting to concentrate on its cable television franchises. Its early demise was heavily fueled by an expensive anti-satellite-TV campaign launched by its cable television division. Since it was one of only two commercial DBS satellite television providers at the time, the ads largely served to discredit their own product.

Progressive scan – This is the opposite of interlaced scan.

PSIP data – (Program and System Information Protocol) This data is arranged as a table with multiple sub-tables. The data identifies the station name, what the sub-channels are, the program name, the following programs, content advisories, language options, and caption options. Some of this data is transmitted as often as 7 times per second.

PVP-OPM – Protected Video Path Output Protection Management. Downgrades computer video resolution or blocks the picture entirely if the connected display doesn’t support content protection.

PVP-UAB – Protected Video Path User-Accessible Bus. Encrypts video content as it passes over the PCI Express bus from the high-def disc to prevent other PCI Express devices from intercepting the video stream.

Rainbow effect – A side effect of delivering the image colors sequentially instead of simultaneously. DLP displays have this effect if they use a spinning color wheel or sequentially-firing LEDs. Most viewers are not bothered by the rainbow effect.

Raster – A group of closely-spaced lines whose brightness changes so as to appear to be an image.

RGB – 1. red-green-blue 2. a 3-wire standard (See component video) 3. a 5-wire standard (See VGA.)

RGBHV – See VGA.

Screendoor effect – If each pixel has a dark border around it, viewers who sit too close can see it. The effect is somewhat like looking through a screendoor.

SDTV – (standard definition TV) SDTV is 480i, which is approximately the resolution of NTSC and DVDs.

SECAM – (Sequential Color And Memory standard) This alternative to NTSC. This analog television transmission standard has 625 lines interlaced at 50 fields per second. It is used in the former USSR, France, and parts of Eastern Europe, the Middle East, and Africa.

SPDIF - (Sony/Philips Digital Interface) This is digital audio, and can be either coaxial cable or fiber optic.

Spotlight – A pay-television channel launched on C-Band by Cox Cable in the late 1980′s. It was intended to replace HBO as the main pay channel on all Cox franchises. Customer complains and lack of support from major studios led to an early death for this channel. It survived for less than 4 years.

STB - (Set Top Box) These include satellite receivers, cable TV receivers, OTA receivers, and various recording devices.

Sub-channels – OTA DTV stations can show multiple programs simultaneously, subject to the 6 MHz bandwidth limit. This is called multicasting.

SVGA – Super VGA. See VGA.

S-video – Also called Y/C, this two-wire standard keeps the color separate from the intensity signal, and thus avoids the overlapping sideband problem of composite signals. (Converting an NTSC signal to S-video gains you nothing since what was lost cannot be recreated.) Although the quality of S-video is close to component video, S-video cannot transport anything better than 480i.

Symbol rate – The symbol rate for ATSC is 10.76 million symbols/sec. 8VSB has 3 bits/symbol. After the error correction bits are removed the net transfer rate is 19.28 million bits/sec.

THX – 1. a standard that theaters try to meet. 2. equipment to help theaters meet that standard.

Toslink – A fiber optic cable standard.

Transponder – A satellite channel. There is often one program per transponder. Some transponders are wider than 6 MHz and can carry more than one NTSC program. Several digital channels can fit on one transponder.

TVRO – Television Receive Only. The earliest C-Band satellite television systems were referred to as TVRO systems. This was to distinguish the home dish reception systems from “uplink” dishes, which actually transmit signals to satellites, and thus require proper licensing from the Federal Communications Commission. The earliest systems were roughly the same size in diameter as uplinks, often being 10 meters, or around 20′ wide. Most early parabolic dishes also featured solid aluminum, steel or fiberglass reflectors, as opposed to mesh C-Band systems that became popular later on.

VC1 – VideoCypher 1. A legacy TV encryption standard invented by Macom/General Instruments. It was the first satellite television encyption standard to digitally encypt both the audio and video portions of an NTSC signal. Based upon the original 64 Bit DES encryption standard, it is now considered too weak an encryption scheme for transmission of sensitive data. Its use was very limited, due to the high cost of the technology at the time. The earliest adopters were the CBS Television Network for its network TV news feeds on C-Band, and NASA, which used the technology to encrypt video transmissions during space shuttle missions conducted for the United States Department of Defense (DoD).

VC2 – VideoCypher 2. One of the earliest encryption standards used in satellite television, primarily for C-Band signals. Introduced in the late 1980′s, it encrypts NTSC video using analog sync destabilization and audio using a proprietary digital format. It is still in use with some C-Band broadcasters.

VGA – a 5-wire standard interface, originally for computer monitors, now common for HDTV monitors. Usually the 5 wires are in one cable. The connector can be either a 15-pin connector or five BNC connectors. The signals are usually red, green, blue, horizontal sync, and vertical sync. But Y, Pr, and Pb can replace the colors.

Virtual channel number – This is the channel the consumer thinks he is watching. The actual (physical) channel is selected by a hidden mechanism.

YCrCb – Almost identical to YPrPb. If you connect a YCrCb unit to a YPrPb unit you might have to adjust the color slightly. YCrCb is an older standard uncommon for consumer connections.

YPrPb - Color representation requires three independent variables. CRTs prefer red, green, and blue. Ink jet printers prefer yellow, magenta, and cyan. NTSC encodes color as luminance (brightness), hue (color), and saturation (absence of white in colors). Storage media such as DVDs prefer Y, Pr, and Pb, where Y is luminance, Pr is red-Y, and Pb is blue-Y. This is because Pr and Pb can be at lower resolution and not degrade the image noticeably, thus saving storage space.

YPrPbHV – See VGA.

3:2 pull-down This is the process of converting a 24 frames/sec image into a 30 frames/sec image. Some line-doublers will reverse this process to acquire the original, and then re-perform it.

4DTV – This is a DTV subscription service for C-band and Ku-band. Transponders are digitally encrypted using a proprietary format.

5.1 channel – This is 6 channel audio. The 6th channel (the sub-woofer) has reduced bandwidth.

5C Copy Protection – See DTCP.

8VSB modulation technique – (8-level vestigial sideband) DTV stations in the U.S. use 8VSB modulation. This is an AM mode wherein the carrier is multiplied by an 8-level digital signal, and then a filter is used to remove all but the carrier and 6 MHz of the upper sideband. (“8VSB” is often used as a synonym for OTA.)

ETG currently owns the vast majority of television stations in the Eureka, California market. These include KVIQ Channel 6 – a CBS affiliate, KBVU FOX-29 – a FOX Television Network affiliate, KUVU – the local CW affiliate and KEMY – a low-power station broadcasting material from the “MYTV” network.

In a nutshell, there are no TV stations in the Eureka, CA, market that are uplinked to, or available from, DirecTV or DISH Network. These are the only two companies legally allowed to offer network satellite television services to consumers in the United States. ETV will NOT grant satellite viewers waivers in order to receive network programming from other stations. So, if you live just about anywhere in Humboldt County where cable television or a broadcast signal is not available, you will likely not be able to view any type of broadcast network programming (legally).

For those of you who happen to live in “wired” areas of Humboldt County, SuddenLink Communications offers all local Over The Air TV channels (albeit in analog, with no plans for HDTV on their basic tier) for approximately $15 per month. SuddenLink is the only major cable television provider in Humboldt County, and covers most areas in and around the cities of Eureka, Arcata, Fortuna, Rio Dell, McKinleyville and a number of smaller, unincorporated areas. The majority of residents in Humboldt County have access to cable, since the majority live in and around the county’s major population centers. However, this is not to say that cable TV is available in most of the area of Humboldt County in a geographic sense. Travel more than 500 feet from any major road or street, and there is a 99% chance that cable television will be completely unavailable to you.

Broadcast availability is another matter altogether. This is largely dependent upon how far you are from the TV station’s broadcast transmitter, terrain and what type of equipment you are using for reception. The vast majority of Humboldt County falls into what the Federal Communications Commission (FCC) describes as a “Grade B Contour Area”. Generally speaking, this is defined as an area where a “watchable” signal should be available using an outdoor TV antenna placed at a height of 30′ above the ground.

Like most TV and FM stations in Humboldt County, ETG’s stations broadcast their signals from a transmitter facility atop Kneeland Mountain, which overlooks Eureka, Arcata and the more populated areas of Northern Humboldt County. The further away you are from Kneeland, the weaker your signal will be, generally speaking. When it comes to UHF and HDTV or digital television signals, you will most likely need line-of-sight in order to actually get a watchable signal. This is even more important when talking about low-power television (LPTV) stations, which 3 of ETG’s stations happen to be.

Having installed antennas in many parts of Humboldt County, I can say from experience that the FCC’s entire “Grade B Contour” requirement is entirely inadequate when it comes to checking for signal availability. These charts are generated by engineers using computers to determine where a signal should be available, but fails to take into account quite a number of variables that are detrimental to receiving a signal. Having a line-of-sight view of the transmitter tower on Kneeland, along with an adequate antenna system, is the only way to assure that you will have a watchable picture.

ETG’s signal coverage maps give at least a rough estimate of whether a TV signal will even be possible to receive in your area, so I highly recommend taking a look at them before spending any money on an antenna system.

Subject: “A View from the Digital Divide DTV Front”

I’m not really sure how to address the issues in the article, so I’ll just try making a few points and suggestions below. Many, if not most, of these points would not be understood by the average consumer, but that’s another matter:

Mistake #1 - Buying a converter at Best Buy. You are far better off buying online or via mail order from a company that specializes in broadcast or Over The Air (OTA) antennas than purchasing one art a mass market retailer like Best Buy. Probably the best place you can shop is at solidsignal.com . They have a wide range of boxes, many of which are cheaper than the one you purchased in the article. They also have excellent customer service and can make some useful suggestions by phone. You can also compare a number of boxes on websites such as amazon.com as well.

Mistake #2 - Listening to a salesperson at Radio Shack. Let’s face it, if someone really knew a lot about local broadcasting, they probably wouldn’t be working at Radio Shack to begin with. The suggestion for you to buy an in-line amplifier to solve your problem of lack of signal strength was just plain stupid. Radio Shack is no place to look for expert advice.

Mistake #3 - Looking for antenna installers. If you couldn’t find a few hundred antenna installers in the state of New Jersey, you were definitely looking in the wrong place. If you are going to use the Yellow Pages, try looking under “satellite television”. The satellite installers that have been around for a long time also commonly install broadcast reception antennas as well. They just don’t want to spend the money on advertising to the small audience that buys OTA antennas. In particular, look for a dealer that does more than just DirecTV or DISH Network only. The dealers that install C-Band dishes and do commercial installs are your best bet. They will know the inside scoop on your local broadcasters better than anyone at Radio Shack.

Mistake #4 - $300 for an outdoor antenna??? I’m not sure what antenna you bought, but if you are doing a self-installation it should not cost anywhere near that much. I bought my own OTA antenna from solidsignal.com and paid around $75. That antenna is longer than I am tall and provides far better reception than most people would ever need. Unless you are running more than 100′+ of coaxial cable, you shouldn’t need an amp and the rest of the costs (cable, connectors) are pretty minimal. It might be cheaper to figure out EXACTLY how much cable you need, then buy it by the foot at a local hardware store, rather than buying a whole spool or a 100′ length with the connectors already crimped on.

Mistake #5 - Assuming that the signal you get today is similar to the one you will get after analog broadcasting is phased out. The fact is, very few people are actually watching their TV via digital Over The Air broadcasts right now. Most of them are still tuning in the analog channels or get their signal from the cable TV company or by satellite. The broadcasters know this. Since many broadcasters are still “toying” with HDTV, quite a number of them are only broadcasting a digital signal on limited schedules or are using limited transmitter power to save money on electricity at the moment. After all, if they are simulcasting both digital and analog signals at the same time using the same amount of power they are having to pay DOUBLE the electric bill, which is a big concern for many small stations. I think you’ll find that once the old analog signals go away, you will see broadcasters start firing up their transmitters at full power. It makes quite a difference when a broadcaster goes from a minimal 50 Watts to a full 200,000 Watts.

Mistake #6 - Expecting to get the same number of channels that are on analog. I’m sure that there are quite a number of low-power (LPTV) channels that will never make the conversion to digital, because they simply can’t afford transmitters at this point. Quite a number of other stations simply don’t have their digital systems set up yet, or are only broadcasting on a limited basis. Quite a few of them will likely wait right up until the last minute to make the transition. Until then, you should still be able to receive them on analog. Bottom line… Don’t take “overlap” of analog and digital for granted! Expect one or the other, but don’t expect to get a perfect signal from both. After all, it’s not like you are actually going to watch BOTH the analog and digital version of the same channel.

Mistake #7 - Forgetting the past. People these days quite simply take getting a decent TV signal with little or nothing for an antenna for granted. It wasn’t always that way, nor was it ever intended to be that easy to get a picture. In the early years of TV broadcasting, an outdoor antenna was almost always required, but people weren’t complaining about it back then. The only reason that it is so easy to get a signal with “rabbit ears” these days is because the shift from TV receivers using tubes to solid-state technology has made pulling-in a watchable picture infinitely easier. Solid-state amplifiers are much more sensitive and produce much less “noise” than vacuum tubes. If you tried plugging-in a circa 1940′s TV set in the same location you are in right now with rabbit ears, you wouldn’t get any picture at all. If anything, it cost far MORE to buy a TV and antenna (when you take inflation into account) back in the “old days” than it does today. Broadcasters are already pumping out signals using hundreds of thousands of watts of power. It’s the consumer’s job to turn it into a watchable picture. TV was not initially designed to be that easy to pick up. Older Americans would probably be the first to remember this. To be honest, today’s generation has been rather spoiled after growing up with cable TV or satellite television. Over The Air reception will never compete with those technologies when it comes to how easy it is to get a “perfect” picture.

Mistake #8 - FCC testing of HDTV converter boxes. ALL boxes sold in the U.S. have to be granted FCC type acceptance prior to being imported into the country or sold. Some companies have gone through the additional steps of getting their products “certified” for use with the coupon program as well. As for “practical” testing, there really is no need for it. Nothing that happens in the world of broadcasting is anything more than a matter of math. An engineer can tell you exactly what signal level to expect at a specific location well prior to hitting the transmit switch. Most products these days are only “simulated” before going into mass production. Even airplanes. The FCC has already “done the math” on the issue and broadcast engineers have already calculated the specs each broadcaster would need to get the same coverage as they had previously and what specs receivers would have to meet in order to receive them. There is no guess work going on here. It is simple math.

Mistake #9 - I wouldn’t exactly call this a mistake, but more of a reality check. All electronics products eventually become obsolete. Some sooner than others. Just ask anyone who has owned a Betamax (or any VCR, for that matter), video disc player, CD mini-disc player, Digital Audio Tape players, 8-Tracks, cassette players, 78 RPM record players, Windows 95 or any number of other examples. Some products far, far more expensive than portable television sets have been pulled from the market after as little as a few months in the past. How about all of the people that rushed out at bought non Blu-Ray HD-DVD players are getting their money back? TV sets purchased in the late 1930′s still work today (albeit in black and white). I’d say that most of these people have gotten their money’s worth by now.

Let’s not forget that the broadcasters themselves are being forced to shell out millions of dollars on new equipment, and that the FCC has pushed back the final switchover date on HDTV numerous, numerous times in the past at their request. It’s either now or never. The rest of the world is passing us by. The previous delays have already led to our version of HDTV being a half-baked solution compared to newer technology. Let’s just get on with it. I hope you find some of this info useful.

HDTV Is On The Way

HDTV and DTV service is coming soon to a television set near you, even if you live in Humboldt County. In February of 2009, most broadcasters across the county will be changing the frequencies that they currently broadcast at and start transmitting their signals in an all-digital format called DTV (Digital Television). The only over-the-air analog TV signals remaining will be that of Low-Power Television (LPTV) stations.

U.S. Government To The Rescue?

Many would argue that the Federal Government seems to be helping its citizens adjust to digital television in much the same manner as it helped the victims of Hurricane Katrina. Too little, too late. Few people seem to know what the transition to DTV will mean, or how it will affect them.

For those of you who do not have HDTV-ready television sets, the federal government has coupons for you. That’s right, every household in the United States is eligible to receive up to two (2) coupons good for $40 each towards the purchase of a government-approved “CECB” converter box. This box will allow you watch digital TV (DTV) signals on older, analog TV sets. Think of this as a bonus on top of your IRS “economic stimulus” check. Unfortunately, all of the CECB receivers we have found currently retail for $50 and up. It is highly questionable whether these converters will ever reach the $40 mark, making them free to consumers.

You can receive your coupons via mail from a program run by the National Telecommunications and Information Administration, which is a division of the U.S. Department of Transportation. Why the program is not administered by the Federal Communications Commission, I have no clue. In any event, you can apply to receive your coupons online at the website address: https://www.dtv2009.gov/ApplyCoupon.aspx , or call 1-800-DTV-2009 to get the forms mailed to you.

Once having filled out the form, you will be placed on a waiting list to receive your coupons. You will have less than 90 days to make use of the coupons once you receive them. Locally, you should be able to buy one of these CECB converters at Radio Shack, if they are in stock. I have even seen them sold at Walgreen’s in Fortuna recently. If you want to purchase a box over the Internet, the situation is a bit more muddled, since most online checkout systems have absolutely no clue as to how to handle discounts from a government coupon. You can currently find many units available on Amazon.Com though.

What Will Happen

If you are a cable television subscriber, you will not need a new converter in order to watch channels on cable, before or after February 2009. Most cable channels are already transmitted in a proprietary digital format that can only be decoded by their own cable converters. If you already have a cable converter that is leased or sold to you by your cable company, that should be all you need. On some cable systems, channels on “basic” tiers will continue to be transmitted to subscribers in the pre-2009 (NTSC) analog format. If a local station switches to digital, the cable company may decide to “downconvert” the station’s digital (DTV) into analog, which would allow you to continue receiving local channels without a DTV converter box. That decision is up to your local cable television provider though.

If you subscribe to television service via satellite (i.e. DirecTV or DISH Network) you will not need a new converter to watch HD signals, because satellite broadcasters also use their own type of proprietary digital format. The DTV switchover should not affect you at all.

If you receive TV broadcasts via “rabbit ears”, an outdoor antenna, an antenna built-in to your television set or even just a coat hanger, you WILL need a CECB converter box in order to watch most local television stations after February 2009. If you already have an HDTV-Ready television set, it already has a digital tuner built-in. No converter should be necessary in that case. Almost all plasma and LCD flat screen TV sets sold in the past two years have digital tuners built-in. You will only need a converter if you have an older set that only tunes-in analog TV signals.

DTV VS. HDTV

So, what is the difference between DTV and HDTV? All full-power (non-LPTV) broadcasters will be switching to DTV in February 2009. DTV simply stands for Digital Television. It produces a picture that is arguably equal in quality to a traditional analog TV signal, which is what most broadcasters currently use.

On the other hand, High Definition Television (HDTV) is unlikely to be used by the majority of broadcasters for some time to come. It produces a much higher quality picture than traditional analog or standard DTV broadcasts. However, it is still a very expensive broadcast technology to deploy, and few stations will be switching to it in the near term. All television stations that broadcast HDTV signals will be doing so via a digital signal (DTV). However, few who broadcast in DTV will have HDTV. Clear as mud?

What You See…

You will NOT be able to see the “High Definition” version of DTV broadcasts (if HDTV is broadcast locally) any more than you would be able to listen to a stereo TV broadcast with a TV that has only one speaker, or a color broadcast with a black-and-white TV, even if you have a converter box. Only HDTV ready televisions are capable of displaying the higher definition picture.

The CECB converter boxes will at least allow you watch DTV programming in standard resolution after the old VHF and UHF analog channels have switched to digital in 2009 though, and you will be able to use them to receive most local TV stations in Humboldt County right away. Keep in mind, these converters are only meant to pick up OVER-THE-AIR, local broadcasts. So, you will still need an external antenna of some type to pick up a signal. If you are not currently within range of analog TV reception, a converter will not likely be of much use to you.

Recent Experimentation

I currently use a standard HDTV set at my home in Eureka and receive most of the local stations in DTV using a fairly large, outdoor, mast-mounted UHF Yagi antenna. I can’t say as I am all that impressed with the type of signal that I receive from most local broadcasters, but it is a better picture than I could get on many of the older analog simulcasts. My house actually resides BELOW sea level, so I am probably lucky to get any signal at all.

Unlike with analog broadcasts, DTV is an “all-or-nothing” type of proposition. You will either get a perfect signal, or none at all. In that regards, it is much like satellite television. Gone will be the days of watching TV in fringe areas with weak reception. You will either get a signal, or you won’t. Occasionally, you may see the signal fading in quality due to weather conditions. When this happens, you will typically start to see what is called pixelation on the screen. This may be followed by the screen “freezing” on a single frame, or going black altogether.

This “all-or-nothing” DTV quality has its obvious downsides, but in most cases much can be done to improve the chances of receiving a signal just good enough to keep the tuner “locked” on a channel. By far, the best investment you can make is in a high-gain, directional, outdoor UHF TV antenna. These come in a variety of shapes and sizes. Generally speaking though, the bigger, the better. A 10′ long “ugly” rooftop antenna will always outperform a “cute” looking circular antenna or pair of rabbit ears.

What Type of Antenna?

First of all, I highly advise you NOT to buy any antenna that is small enough to set on top of your TV set, even if it has an amplifier built into it. The whole concept of adding an amplifier to an antenna that is only inches away from your TV set makes little sense. While the signal of the DTV stations may be increased by the amplifier, so will any background noise or interference. To make matters worse, indoor antennas suffer from what is called “multipath”. Indoors, a TV signal will bounce off walls, doors and other objects much the same as light will bounce off a mirror. Unfortunately, DTV does not handle multipath situations very well. You will be infinitely better off with an outdoor antenna that has a line-of-sight view of the station’s transmitter.

So, what will you need in order to set up a proper antenna for DTV reception? The materials are much the same as are used when installing a home satellite dish. The majority of the cost will be in the antenna itself.

Most high-quality, directional, outdoor antennas are referred to as Yagi antennas. The name came from the designer of the original antenna concept. These antennas will give you the most DTV bang for your buck. The outdoor antenna should be connected to your television or converter box via high-quality RG-6 coaxial cable, which is the same cabling used in satellite and most cable television installations. Each end of the cable must be fitted with “F” connectors, which are available from any hardware store. You can usually buy coaxial cable with F connectors already fitted to each end in 25′ lengths.

You will also need an antenna mast. These can typically be found at Radio Shack or at local hardware stores. They usually come in heights of 6′ and 10′. You may be able to save a few bucks by substituting metal pipe for an antenna mast. In that case, look for pipe that has around a 1.5″ outside diameter.

Lastly, you will need some type of mounting bracket. There are numerous types of mounting brackets for antenna masts, depending what you plan to mount the mast on. There are mounting brackets specially designed to affix your mast to a chimney, among other things. Typically, you will be mounting the antenna on the side of a house though. These brackets are easy to find online and locally at places like Radio Shack.

If you have to run at least 75′ of cable between your antenna and DTV receiver, it might be a good investment to purchase a mast mounted pre-amplifier. The best place to amplify a signal is as close to the antenna itself as possible. The closer to the receiver an amplifier is located, the less good it will do you. If you are unsure of whether you will need a pre-amp, you can always buy one after installing the antenna, later on. They are relatively simple to install and will mount on the mast directly below the antenna itself. Your money will be best spent investing in as big an antenna as possible first though. Only if you still can not get a watchable signal should you then consider adding a pre-amp.

One other option that you may want to consider if you are in a very “fringe” DTV area is an antenna rotor. What does it do? To put it simply, an antenna rotor allows you to rotate your outdoor DTV antenna at a 360 degree angle without having to go outside and move it manually. While the majority of television broadcasters in the area transmit their signal from somewhere high atop Kneeland Mountain, there are stations like KIEM-TV that place their main transmitter and low-power translators in alternative locations. It might be necessary in some cases to change the direction your antenna is pointing in to get a decent signal from each station. A good quality rotor is a significant investment, so you will definitely want to see if you can get decent reception without using one at first. Most rotors these days come with a wireless remote that will store the position of your favorite channels in memory. If you are unsure of what type of antenna rotor you will need for your particular installation, it is best to ask a professional. As is the case with most antennas, the bigger, the better. An underpowered or cheap-o rotor is the part of your system that is most likely to break-down first, especially if you live in an area with high winds.

What NOT To Buy

If you rely solely upon advice from a salesperson at a local electronics store, you are bound to be disappointed with what you have paid for. The majority of salespeople have never installed an antenna, and most are paid a higher commission for selling you the most expensive solution possible, NOT the BEST solution possible. If you need advice, go to a website or shop locally with a dealer that specializes in selling Over The Air antennas. If you can’t find one, look for dealers or installers that handle satellite television equipment. Many of the older satellite dealers have extensive experience in installing Over The Air antennas.

Some items that you should definitely steer clear of are things such as worthless gold-plated connectors and accessories. None of these will improve your signal significantly. In fact, most brands only use gold plating for the ground portion of the connector, which doesn’t even carry the signal! These overpriced items exist for one reason only. To sucker people out of their money. If you meet a salesperson claiming that anything gold-plated will improve your signal, don’t walk away… RUN!

Another nearly worthless contraption is the small, indoor antenna that is shaped like a satellite dish. You will be no better off with these than with a 99 cent pair of “rabbit ears”. Like gold-plated connectors, these things are for cosmetic purposes only. The “dish” portion of the antenna serves absolutely no functional purpose whatsoever.

You should also avoid in-line amplifiers on short runs of cable (i.e. 75′ or less). Line amplifiers are only meant to help in conditions where there is a significant loss of signal between the antenna and the receiver. Unless your antenna is a very long distance away from the receiver, a line amp is not going to do you much (if any) good. It might even make the picture worse.

“Flat antennas”, circular antennas and omnidirectional antennas will only work well in limited situations, where you are very close to a TV station’s transmitter. A traditional, directional antenna will always outperform these, and usually at a lower price. The bigger and uglier the antenna, the more likely it is to work well. The less something looks like an antenna, the less it tends to perform like an antenna. The only situation where I would recommend these types of antennas are in situations where zoning restrictions do not allow you to erect a real antenna, or if you live in an apartment building.

“House wiring” antennas are also just a gimmick. They claim to use your home’s electrical wiring as an antenna for television reception. There are many, many reasons why these devices do not work as advertised. They might sound good in theory to the average consumer, but anyone who knows anything about antennas knows that you would be better off just using a coat hanger and saving your money.

Snap-On F connectors are completely inferior to threaded, crimped on F connectors. Avoid any cable with connectors that are not threaded. Similarly, you should avoid bargain-brand RG-6 coaxial cable if you want good reception. Good quality coaxial cable is the second most important part of any antenna system, next to the antenna. Belden makes quality cable. That brand is usually a safe bet. The more shielding coaxial cable has, the better. Typically, high-quality RG-6 coaxial cable will feel a bit “stiff” and you will have a difficult time bending it at a 90 degree angle. Never use cable that has a “floppy” or “rubbery” quality to it, or that appears smaller in diameter to other RG-6 cable. Do NOT use RG-59 or other types of coaxial cable that are cheaper, but inferior in design.

How To Get HD On Your HDTV

So, you’ve spent a lot of money on a fancy, new flat panel, HDTV ready TV set. The picture may have looked great when you saw it in the store at Costco, but it looks lousy in your living room. What’s the deal? First of all, you can bet that the picture you were watching at the store was from either satellite or a Blu-Ray DVD player. If you want the best picture you can possibly see on your HDTV set, you will need to buy a Blu-Ray DVD player or a Playstation III console that has one built in to it. At the moment, these players are still rather pricey. Eventually, they will replace most home DVD players. For the moment though, you will have to shell out some serious cash for both a player and the limited number of discs that are available for it.

If you thought that you might be able to get an HDTV signal over the air for free with an antenna, you are in for a long wait. No local broadcasters have yet announced plans to offer their signals in HDTV. They are not required to do so by law, and it will likely be years before any stations are broadcasting in high definition.

So, what are your alternatives? Right now, cable and satellite subscription services are your only real options. The local cable company in most of Humboldt County is SuddenLink Communications. They claim to currently have up to 21 channels available in HD. Pricing for their services are not published, so we can’t give you an apples vs apples comparison to satellite TV providers whom openly advertise their subscription rates.

The United States currently has two DBS satellite providers who offer service to consumers via small, pizza sized antennas. They are DirecTV and DISH Network. Currently, DirecTV has the most HDTV channels and programming available. When comparing the two side-by-side, DirecTV is definitely the leader when it comes to the number of channels available, number of sports packages available and in receiver technology. DISH Network mainly advertises themselves as an alternative to cable and is a bit more competitive on price.

Little Known Alternatives

There are a few sources of HDTV programming that the majority of the public is totally unaware of. They are usually more expensive than cable or standard DBS service, but are worth considering if you can afford it.

The first alternative is a C-Band satellite system with a 4DTV receiver. C-Band satellites operate on different frequencies than that of DBS providers. These were the first satellite systems available to home users, and generally require a dish antenna that is at least 6′ wide. In Humboldt County, which has marginal reception of most U.S. satellites, I would not recommend anything smaller than a 9′ dish. Next to Blu-Ray, the HDTV picture you will get with C-Band 4DTV programming is the best you can find. Programming packages are much more flexible than with DBS providers and subscription services are the cheapest you will find anywhere. The trade-off is the expense involved in setting up a C-Band system and the amount of space it will take-up in your yard. Expect to spend in the neighborhood of $1,500 or more to have such a system installed. This is definitely NOT a “do-it-yourself” type of project if you are unfamiliar with how these systems work. The biggest upside with these systems is the fact that you can get a lot of programming “in the clear”, which means free and unscrambled, that is quite simply unavailable anywhere else. With the proper hardware you can pull-in hundreds of TV channels and radio stations across North America and even some from Central America. A C-Band system is the ultimate in home entertainment. No cable or DBS system in the world provides as much programming as is available using a “Big Ugly Dish”. Still, only a small percentage of it is currently broadcast in HD.

Another alternative that is well beyond the reach of most consumers is the unadvertised DirecTV Titanium package. For $7,500 a year, you get every single channel that DirecTV broadcasts. This includes all HDTV channels, all pay-per-view movies and events, all local network affiliates… everything. I can’t imagine anywhere else that you could possibly get more HD programming from. It certainly isn’t cheap though.

Lastly, the most obscure programming source for HD comes from our neighbors to the North… Canada. There is a little-known “grey market” in satellite television programming that involves StarChoice, which is a DBS programmer that is only legally allowed to sell it’s services in Canada. StarChoice is one of two DBS providers that serve Canada. Neither DirecTV nor DISH Networks are legally allowed to be sold there, so Canada has it’s own version of DBS. Many of the channels on StarChoice are just American cable channels and broadcast networks, much as you would get from a U.S. satellite or cable provider. However, there are a number of exclusively Canadian channels on StarChoice as well. You can also receive the U.S. broadcast networks in both Eastern time AND Pacific time. The number of HD channels is currently limited, but growing. So, what’s the catch? The catch is… you can’t “legally” buy the programming in the U.S. However, there is at least one company that will act as a “broker” and resell you the service for a yearly fee. They take care of all the billing, and provide StarChoice with a phony Canadian address and contact name in order to get your service authorized. The company is able to do this through a loophole in current international law. While being technically a copyright violation, you are still paying for the programming, so shutting down these types of services is not a big priority for law enforcement and I’ve never heard of anyone being prosecuted for such a “crime”. Still, it involves some amount of risk. Try searching Google for more information on these services. You will be amazed at the amount of original programming you can get for a rather modest price.
