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.

The bill still needs to be approved by the U.S. Congress before it is signed into law by President Obama. Both the President and Congress have indicated their willingness to see the law passed. The original deadline for the transition to digital television was February 17th.

“Delaying the upcoming DTV switch is the right thing to do,” said Senate Commerce Committee Chairman Jay Rockefeller, D-W.Va., author of the bill to push back the deadline. “I firmly believe that our nation is not yet ready to make this transition at this time.”

It is presumed (details on the bill are not public yet) that the bill also allocates an additional $25 million in funding to The National Telecommunications and Information Administration, which is the government agency responsible for dispersing $40 discount coupons for set top CECB converter boxes. The converter boxes allow those with analog television sets to decode the DTV or HDTV signals for viewing, albeit with degraded picture and sound quality. To get on the waiting list for coupons, U.S. residents may call 1-888-DTV-2009 or visit the TV Converter Box Coupon Program at http://www.dtv2009.gov.

Up until today, the looming DTV transition deadline in February and the current shortage of coupons sent by the government had created a miniature black market for the items. Ads on Craigslist.Org and auctions on eBay had been demanding higher and higher prices. This should put a quick end to most of these ads, which were being quickly deleted by each of the two websites. It is currently against federal law for anyone to sell DTV converter coupons.

The below list was compiled from the U.S. Department of Commerce (NTIA), and is current as of January 2008. We’ve added an *asterisk in front of stations licensed in Humboldt, Trinity, Del Norte and Southern Mendocino Counties in Northern California. Keep in mind, these stations all transmit using very little power, so picking up any of them is rather tricky. As far as I know, this is the most comprehensive list of translators available for the area, and the only one that lists network affiliations and the names of the stations that operate invividual translators.

One fact that I find particularly interesting is that we have more LPTV stations and translators in rural Northern California than you will find in any major metropolitan area, such as Los Angeles or San Francisco. In fact, San Francisco seems to only have a single LPTV broadcaster. Also, the localities given do not always seem to reflect the actual location of the translators in all cases. Broadcasters are not required to disclose the “exact” location of their transmitting facilities, which can make it extremely difficult to determine which direction to point you antenna in for the best reception. This is especially true at UHF frequencies (channels 14 and up), where you likely won’t see any signal at all if you don’t aim an antenna in precisely the right direction.

Another interesting factoid is the large number of low-power television stations that have been licensed in the Eureka area. Despite having been granted construction permits, none of the channels currently assigned to “MS Communications” have ever broadcast a signal, to the best of our knowledge. Apparently, MS Communications holds the licenses for literally hundreds of LPTV stations across the country, none of which seem to be operational. It is doubtful that there will ever be any television programming on these stations.

We’ve added comments where appropriate, including network affiliations.

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 .

First of all, filling out the online form is easy. There are a minimal number of questions. You can fill out the entire form online at http://www.DTV209.gov . It takes only a few minutes. You can also call their toll-free number at 1-888-DTV-2009. You will be walked through the application status over the telephone. Either way, the application process asks pretty much the same questions, and you will get your coupons just as fast one way as the other.

There are some “catches” with the application process. Considering the fact that this program is administered by the federal government, the whole system runs fairly smoothly though. The biggest “catch” is the fact that if you want to get the coupons in the first place, YOU HAVE TO APPLY FOR THEM! You won’t get them automatically if you fail to apply. There are only a limited number of coupons that are being produced, although the feds won’t tell us the exact number. Either way, availability is on a first-come, first-served basis. Once they are gone, they’re gone.

The second “catch” can be a bit of a pain for many rural Americans. This is rather ironic, since those in rural areas are the ones most directly affected by over the air signal reception of DTV signals. In a nutshell, you will have to give the government a physical “street” mailing address in order to get your coupons mailed to you. You can NOT use a PO Box as a mailing address. You can NOT use a business address to send your coupons to. You can NOT use a service such as Mailboxes, Etc., The UPS Store or other private mailbox provider. You can NOT have the coupons shipped to you overseas or to any domestic address that does not match-up with a (very buggy) database of residential addresses maintained by the U.S. Postal Service. This is a rather unforgiving process, unfortunately. You will need to enter your street address information EXACTLY as it appears in the USPS database, otherwise your application will be rejected. So, what do you do if you live in a remote area and you do not have a “street address” that is serviced by the U.S. Postal Service? At this point, insofar as we can tell, you are just out of luck. Sorry.

The same goes for any legitimate street address that the USPS has “mucked-up” in their database. From previous experience, I can tell you that this database is horribly inaccurate in many cases. For example, the business address that I have used for 10 years to receive postal mail, UPS shipments, FedEx deliveries, freight deliveries, my income tax and voting materials, driver’s license, etc. does not exist at all in the USPS database. Funny, I still get mail there every single day though. Go figure! In cases like this, you may want to try calling their toll-free phone number at 1-888-DTV-2009 instead, since you will not get anywhere with the online application system.

So, you’ve called or filled-out the DTV converter box application online. Now, what? Sit. Wait. Check your mailbox again, and be prepared to wait a bit longer. A very informal survey we did recently indicated that it took approximately 20-30 days for consumers to receive their DTV converter box coupons in the mail. You will eventually receive a standard sized #10 envelope with a couple of pages of information and (usually) two “coupons”. They don’t look like your average coupon though. They look more like credit cards. There is a mag stripe on the back of each plastic card, as well as a serial number on the front. The mailing will most likely come from TV Converter Box Coupon Program, PO Box 2000, Portland, OR 97208-2000.

The first page (see above) contains your name and address, the coupon(s) and a list of local retailers where you can supposedly buy a CECB digital TV converter box. These locations are most likely automatically generated from a database that matches your zip code to that of nearby registered CECB converter box retailers. It is far from a complete list though. The one we received (see above) listed eight locations in Humboldt County where the digital television converters are available. They consisted of SEARS, Radio Shack, K-Mart and Target. We do not have a Best Buy, Circuit City, Wal-Mart or a number of other participating electronics chain stores in our area, or they most likely would have been listed first.

The second page (see left) contains some general information about the DTV converter box program. This page also has a list of the most recently approved CECB DTV converter box models that are eligible for the program, although we are guessing that the list will probably be less than 100% up-to-date by the time you get it. Lastly, the insert contains a list of about a dozen or so mail order and online retailers that will accept the coupons and who presumably have the decoders in stock. If you want to read the entire list, see the end of this article for a link to download a digital copy of the insert, which you can print out for yourself.

Lastly, and most importantly!!! If you take away only a single fact to remember from this entire article, it should definitely be to take a close look at the expiration date on each coupon. At most, you will only have 90 days in order to use your $40 DTV converter coupons before they expire. Once they expire, they are absolutely worthless. The government will not give you an extension or re-issue you new coupons. In other words, use them, or lose them! You have 90 days to use the coupons from the day the coupons are printed, NOT from the day that you receive them. As with most bulk mailers, this agency quite likely only sends out their mailings once per week in order to get a bulk discount from the U.S. Postal Service. So, you may find that up to two weeks has been shaved off the 90 days you have to spend the coupons by the time you actually receive them. The government has caught quite a bit of flack over the entire 90 day expiration date issue, but it’s too late for them to make any changes to the program at this point. So, buyer (and taxpayer) beware!

Below are links to graphic copies of the materials you will receive once you register to receive your free government Digital Television (DTV) converters, or CECB boxes. They have been “Photoshopped” to remove certain parts of the serial numbers. Needless to say, you can’t just print these pages out on your inkjet printer and try to pass them off as real coupons. Each DTV converter box coupon has it’s own individual serial number and mag stripe. The information on these pages is for reference and display purposes only.

Free DTV Coupon Insert Page1

Free DTV Coupon Insert Page 2

We will soon publish an updated list of online retailers that can actually process the $40 DTV digital converter box coupons via the Internet. Most online retailers have no way to accept these coupons at present, and most likely never will. A handful of companies have stepped forward to fill this gap, and they are the only ones you should consider buying from online, since you will most likely be overcharged (no discount given) if you try ordering from a merchant that hasn’t made special provisions to deal with these specific coupons.

UPDATE: President Obama and the U.S. Congress officially extended the deadline for broadcasters to switch to DTV to June 12, 2009. You can keep applying for coupons via phone or the Internet until that time. Keep in mind that the extension is basically voluntary, meaning that broadcasters can switch their signals to DTV and STOP broadcasting in analog anytime that they want to. There are very few stations that are waiting until June to make the jump to DTV, due to the high cost associated with simulcasting both digital and analog signals. So, chances are that the only analog broadcasts still remaining in your area are most likely that of translators and low-power (LPTV) stations, which are not required to transition to digital, anyway.

Stay tuned!!!

• 84% of people surveyed know that the transition is happening.
• Almost one-half of those who need to do something to still watch TV on some or all of their sets had inadequate plans or no plans to address that problem.
• While more than one-half of those polled knew about the government’s converter-box-subsidy program, only one-third of those knew how to get the boxes.
• One-third of those who didn’t need the converter boxes or coupons were going to apply for them anyway.
• Some 464,000 ($40 Government) coupons have already expired without being used, or about 58% of the 800,000 that already reached their expiration dates.
• The NTIA’s Bernadette McGuire-Rivera stated that the NTIA has decertified about one-dozen retailers — she called them “bad apples” — that were putting consumers on waiting lists for boxes, getting them to “swipe” their cards so that they could collect the $40 subsidy and then keeping them waiting for boxes that never arrived.

More information on the report is available at Broadcasting and Cable Magazine.

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.)
