What do I need to do to be ready for the end of analog TV broadcasting

 

The Web page http://www.dtv.gov/consumercorner.html contains the following article titled “What do I need to do to be ready for the end of analog TV broadcasting?”

 

“Because Congress mandated that the last day for full-power television stations to broadcast in analog would be February 17, 2009, over-the-air TV broadcasts will be in digital only after that date. If you have one or more televisions that receive free over-the-air television programming (with a roof-top antenna or “rabbit ears” on the TV), the type of TV you own is very important. A digital television (a TV with an internal digital tuner) will allow you to continue to watch free over-the-air programming after February 17, 2009. However, if you have an analog television, you will need a digital-to-analog converter box to continue to watch broadcast television on that set. This converter box will also enable you to see any additional multicast programming that your local stations are offering.

 

To help consumers with the DTV transition, the Government established the Digital-to-Analog Converter Box Coupon Program. The National Telecommunications and Information Administration (NTIA), a part of the Department of Commerce, administers this program. Every U.S. household is eligible to receive up to two coupons, worth $40 each, toward the purchase of eligible digital-to-analog converter boxes. You will be able to request the coupons beginning in January of 2008. The coupons may only be used for eligible converter boxes sold at participating consumer electronics retailers, and the coupons must be used at the time of purchase. Manufacturers estimate that digital-to-analog converter boxes will sell from $50 to $70 each. This is a one-time cost. For more information on the Digital-to-Analog Converter Box Coupon Program, visit the NTIA’s website at http://www.ntia.doc.gov/dtvcoupon/, or call 1-888-388-2009 (voice) or 1-877-530-2634 (TTY).

 

Cable and satellite TV subscribers with analog TVs hooked up to their cable or satellite service should not be affected by the February 17, 2009 cut-off date for full-power analog broadcasting. (True if you have a digital cable box or a satellite cable box.)”


Televisions Services in the San Jose, CA Area

 

There are three choices for Television service in our area (excluding AT&T's limited fiber optic service called U-verse) which are Comcast cable, Dish Network, and DirecTV.  Right now Comcast simulcasts high definition (HD), standard definition (SD), encrypted (QAM), and analog (NTSC) over the cable. Analog televisions and VCR's are only able to receive the analog signals. HDTV's are able to receive HD, SD, and analog signals, and the "channel up" and "channel down" enables selecting the desired type after using the numeric keys to select a channel. Only cable set top boxes are able to receive and decode the encrypted (QAM) channels.  Dish Network and Direct TV use DVB-S (Digital Video Broadcasting – Satellite) forward error coding and modulation standard for satellite television, and the transport stream delivered is mandated as MPEG-2.


Types of TV Tuners

 

There are three types of tuners, excluding those required for satellite. "NTSC" tuners are used to receive the standard analog over-the-air and analog cable channels. "ATSC" tuning allows a set to tune to those same frequencies, but when it "sees" an SD (standard definition) or HD (high definition) signal, it is able to receive, demodulate and decode it. The Comcast set top boxes also have "QAM" tuners built-in to receive and decode Comcast encrypted channels. Satellite set top boxes receive and decode  DVB-S (Digital Video Broadcasting – Satellite).


Aspect Ratios of TV's

 

If you decide to pay for the extra charge for high definition (HD) programming, you have to be concerned about aspect ratios.  Make sure you set each device to the setting that matches the TV to which it's attached: 4:3 for standard TVs, 16:9 for wide-screen monitors (nearly all HD TVs). Aspect ratio is the fractional relation of the width of a video image compared to its height. The two most common aspect ratios in home video are 4:3 (also known as 4x3, 1.33:1, or standard) and 16:9 (16x9, 1.78:1, or wide-screen). All the older TVs and computer monitors you grew up with had the 4:3 shape--only 33 percent wider than it was high. On the other hand, 16:9 is the native aspect ratio of most HDTV programming; it is 78 percent wider than it is tall, or fully one-third wider than 4:3.  For more information see http://www.cnet.com/4520-7874_1-5140690-1.html


Considerations for Choosing a Television Service

  1. Comcast plans to phase out all its analog channels and has already deleted several channels including the TV Guide (channel 11) and Hallmark (channel 66).  Click here for details

  2. Comcast Digital Starter includes Limited Basic and Expanded Basic, and the additional charge for Digital adds only $1.  Click here for details.

  3. Comcast now has about 145 channels on their Digital Starter cable package. Click here to view the channels.

  4. Comcast has channels that can be viewed in 2009 on a digital TV or analog TV with a D/A converter without a cable box.  Click here to view the channels.

  5. Comcast has a onetime DVR install fee of $19.99.

  6. Comcast will be installing TiVo functional software on its DVR’s, and is now testing it in New England. See http://www.hollywoodreporter.com/hr/content_display/television/news/e3ic5807b521d85c7b80f455d3dd8c1edc2

  7. DirecTV and Dish Network worked with TiVo and have incorporated TiVo functionality on their DVR’s.

  8. If you buy a TiVo DVR, the TiVo ongoing monthly DVR service fee is $12.95 per month on an annual basis (was $16.95).  Lifetime contracts for $299 are no longer offered on new purchases.

  9. Since Comcast (in the future), DirecTV, and Dish Network all provide TiVo functionality in their rental DVR’s at a low lease cost that is about equal (Comcast) or less than TiVo’s ongoing monthly subscription charge, it is hard to justify buying a DVR from TiVo.

  10. Both Dish Network’s dual DVR and dual receiver each support two TV’s in different rooms which reduces the number of set top boxes and overall monthly rental cost.

  11. HD (high definition) has an added cost of about $20 (Dish satellite) to about $7 (cable).

  12. From what I have found on the Internet, it appears that all manufactures have stopped making analog VCR’s and DVD/VCR’s with analog tuners.

  13. With a set top box, it is difficult to use a VCR or DVD writer because the channel recorded is determined by the cable or satellite box.

  14. If you have a dual channel Hard Drive DVR, you can record on one channel and watch TV on the other channel.

  15. If you have a dual channel Hard Drive DVR, you can record on both channels and watch a TV program recorded on the hard disk.

  16.  Dish Network’s 500 GB ViP722 HD DVR holds up to 350 hours of SD recordings or 55 hours of HD which is much larger in capacity than a Comcast’s 120 GB DVR or DirecTV's 250 GB DVR.  See http://www.dishnetwork.com/downloads/pdf/product_brochures/722_brochure.pdf

  17. Standard satellite equipment and installation are free (Dish has a $50 deposit that is rebated on the first bill) if it involves no interior walls and does not require an excessive amount of RG6  cable (They state up to 100 feet of free RG6, but our installer used more than that without charging).

  18. Dish Networks 2 TV dual units handle two TV’s in different rooms and come with two remotes (1-IR and 1-RF for distant room).  DirecTV is planning to have similar hardware sometime in the future...

  19. Satellite companies don’t install any required phone extension lines with jacks, but generally provide 25 foot phone extension cords to reach an existing jack.

  20. A  line of sight path to the satellite is required at an elevation of about 43 degrees and an azimuth of about 155 degrees  in the San Jose area.


Cost Comparisons for Television Services  

 

Considering the above items, I evaluated the merits and cost of Comcast, DirecTV, Dish Network, and AT&T Dish for a 200 channels (145 Comcast) four room system with a dual channel DVR  The prices exclude reductions for a limited periods (such as DirecTV’s $10 reduction for the first year or Comcast's 3 month reduction) and local fees & taxes.  The AT&T Dish equipment is the same as Dish Network’s equipment, but booking through AT&T gives an ongoing $4 per month reduction for AT&T customers.  Smaller setups such as a two room system can be derived from the figures shown. 

 

  1. Comcast Digital Starter:  56.99 (less than 200 channels including local channels) + 13.95 (dual DVR) +20.97 (rooms 2-4 set top boxes @ 6.99 each) = 91.91.

  2. DirecTV Plus:  59.99 (200 Channels with 1 TV dual DVR and local channels) + 14.97 (rooms 2-4 receivers @ 4.99 each) = 74.96

  3. Dish Network:  49.99 (200 Channels including local channels) + 5.99 (dual 2 TV HD DVR) + 5.00 (2 TV SD dual channel receiver    = 60.98

  4. AT&T Dish:  49.99 (200 Channels including local channels) + 5.99 (dual 2 TV HD DVR) + 5.00 (2 TV SD dual channel receiver – 4.00 (ongoing AT&T customer discount) = 56.98


My Choice for a Television Service

 

I chose the AT&T Dish four room system that includes 200 channels, a  VIP722 HD dual DVR (500 GB HD)  in the family room (feeds living room TV using an RF remote), SD dual receiver in the PC bedroom (feeds master bedroom using an RF remote).  My total cost per month is about the same as my former Comcast Extended Basic.  There was a $49.99 installation fee which will be refunded on the first bill, so my out of pocket expenses are effectively zero for the AT&T Dish system. 

 

I priced the AT&T Dish system online all the way to checkout, and printed the costs without ordering... Then, I called AT & T, 904 Blossom Hill Road at 408-574-3860 and talked with Jeff Schmidt about possible installation problems.  Jeff said he would give me the same price, so I ordered it though him.


Dish Network Installation

 

On Wednesday November 14, 2007, the installation of our Dish Network satellite TV system started a little before 8 am by one installer and was completed a little after 12 pm.  The installer did an outstanding job of mounting the dish exactly where I wanted it on the peak of the roof in the side yard almost out of sight from the front of the house, and it was a very neat installation.  The signal strength was higher than normal, and the pictures on the televisions were excellent. 

 

The existing Comcast cables were inadequate for "Satellite In" signals, and a RG6 cable had to be run through the attic from the dish to the family room for the dual DVR and a second cable had to be run through the attic from the dish to the PC bedroom for the dual receiver.  Since the TV location in the family room was on an interior wall, the cable had to be run through the attic and down through an interior wall. 

 

To prevent it from being a custom installation I assisted the installer, and I cut out sheetrock from the interior family room wall in two places so that the cable could be fished down the interior wall.  Also, since Dish Network does not install telephone jacks, I fished a standard 4 wire telephone line through the same sheetrock holes and routed in through the attic after the install person left.  The next day, I patched the holes in the sheetrock, and after a few more coats of joint compound, I primed a painted the wall.  The dual receiver installation in the PC bedroom was easy since it was on the wall adjacent to the garage, so the installer was able to get to it by routing that RG6 cable out of the attic and through the garage.  The installer provided an HDMI cable to connect the DVR to my HDTV which is not normally part of the free install.

 

Because we have six VCR’s with two in the family room, two in the PC bedroom, and two in the master bedroom, I cabled them all into the system.  Also, with the setup, I have fed the PC bedroom receiver TV2 Agile modulated output on channel 73 back to the family room so that we can watch a TV show in the family room while two recordings are active.  Since it is so easy to setup DVR recordings from the Guide or a search, we will probably not record any new VHS tapes unless we want to save them permanently, and we will. phase out most of the VCR’s.


Dish DVR VIP 722

 

The Dish VIP722 HD DVR is about equal to the TiVo Series 3 which sells for $599.99 plus tax plus $12.95 per month subscription fee on a 1 year monthly plan. However, the Dish DVR is leased for $6 per month with no upfront cost and seems to have all the TiVo features except a high speed Internet connection even though it has an Ethernet port for future use. It does have satellite pay for view and satellite on demand access to the newest movies for a reasonable price, and it uses a dialup internet connection for paying. Also it has two USB ports for multimedia and an external hard disk.  We record shows in Standard Definition (SD) because 55 hours of High Definition (HD) recording would not be sufficient for our usage.


Television Picture Quality


When I had Comcast cable, I could notice the picture quality difference between analog channels and digital channels on our 32 inch 720p LCD HDTV. However, with Dish Network, I not been able to see any difference between SD and HD broadcast quality even standing in front of the TV and looking at letterings. There is one HD difference which is that you get the correct aspect ratio in HD to fill the full screen, and you don't have to use the "stretch" feature (causes distortion) for a full screen picture. Maybe with a larger 1080p HDTV, one might notice the difference between SD and HD broadcasts. We presently have 6 months of free HD, but I plan to cancel near the end of the free period to avoid an additional $20 per month charge.. Also, since we record everything in SD and primarily watch recorded shows, HD would not be of much value to us. Also, we have 3 months of free HBO and Cinemax which we will also cancel near the end of the free period to avoid an additional $20 per month charge.  HBO is great, but I could subscribe to Netflix for less money.


AT&T Dish Billing

 

My first AT&T bill with Dish Network was a $36.72 credit for Dish Network.  I found the bill confusing at first. When I ordered Dish, I Visa charged $49.99 installation charge which I was refunded on my first bill. Also, I received other credits for 3 months of free HBO & Cinemax and 6 months of free HD (high definition) programming.

After the rebates end, I will cancel both HBO & Cinemax as well as HD Programming, and then my on going bill will probably be as follows:
1. 200 channels package including local channels: 49.99
2. HD DVR with 350 hour SD recording for 2 rooms with RF and IR remotes: 5.99
3. 2 room SD receiver with RF and IR remotes: 5.00
4. State and local taxes: 1.00 (estimate)

5. AT&T customer on going discount of 4.00
Total is $57.98 which is less than my former Comcast analog extended basic subscription for $60.51.

OEM Cable Box and OEM DVR Operating Problems with Comcast Cable

Subject: Re: Converting to Digital Television


Hi Russ,

Here is some of my experiences relating digital tuners. I'm not a good technical writer but will do my best. If you find more information, would appreciate getting it.

-

I purchased a Samsung SIR-T451 over-the-air tuner box (about a year ago) for use with over the air digital stations. Connected it to our UHF antenna and found that most stations are now transmitting digital channels. If fact, Channel 9 has a whole bunch of sub-channels: 9.1, 9.2, 9.3, 9.4, 9.5. Also channel 54 and several other stations have many programs - even programs not available over Comcast. Internet program schedule sites provide listing for all over-the-air channels and sub-channels.

We had analog Comcast service as our primary viewing service. All of our TV sets have analog tuners. Gracia liked the Hallmark channel and in November 2007 Comcast changed that channel to a digital-only channel, so we lost it. I heard from a friend that if a digital tuner was connected to the incoming Comcast cable, you would get a lot of digital channels even if you don't have digital cable service. I tried it and yes, there were a lot of digital channels, but couldn't find the Hallmark channel. The channel format was similar to the over-the-air digital channels in their numbering (i.e. 90.1, 91.2, 92.1, 92.3, 92.4, 92.5, 92.10, 93.8, ..... 119.1, 119.2, 123.40) but didn't correlate to Comcast listings. I also have a Panasonic PV-V4600 DVR that has a digital tuner. It has an auto-channel-detection mode with two options: Antenna and Cable I selected 'Cable' and it found the same (or similar) Comcast channels as found on my digital tuner box (Samsung). Some (most) of the digital channels gave blank (black) screens, but there were about 80-100 channels that had programs running. I couldn't correlate the channel numbers with the regular Comcast channels that go from 1 to 999 with no sub-channels.

For a dollar more ($55 vs $56), we could get introductory digital service with lots of benefits including On-Demand, On-screen menus, and more channels than the analog service. I checked the Comcast internet site and found that they had a special introduction price for digital service for $33.00 per month for the first 3 months. When I went to their store (So. 10th St), they said that the $33.00 price lasts for 1 year. Our price was reduced from $55.00 to $33.00 for this first year. They were very friendly and helpful. In a year, I guess it will go back up to the $56.00 price.

According to the Comcast website, their price included one box rental. Additional boxes could be rented for $6.00 each per month. Their Q&A also implied that if you have other digital tuners, you can receive the digital programming but without the On-demand and Menu features included with their boxes. It sounded like we could receive the digital channels with numbers shown on programming guides. After getting digital service, I expected channels on my digital tuner devices to change, but saw no change in numbering and we still had the sub-channels.

I called the Panasonic service and they said that we need a QAM tuner to receive the Comcast channels and what we were now getting was just 'side bands' signals. He said that the QAM is a proprietary Comcast cable spec but the FCC required Comcast to share it with third party manufactures in July 2007. Panasonic's next recorder to be released in March 2008 may have a QAM tuner.

I have checked the internet and also Fry's Electronics and they have devices with QAM tuners now, but they seem to imply that numbering has the sub-channel format and a maximum channel of 150 -- the same as my current digital tuners. I haven't been able to find a salesperson that understands what's going on. I even read an article in our local community paper by a guy that owns a business that sets-up video home systems and he welcomes questions. I sent him my questions and he didn't seem to give any additional information. My question was. "Getting a new TV set with a digital tuner and using Comcast still requires that the TV set be tuned to channel 3 only (or use video in) and it still requires us to use a digital box rented from Comcast. Why and what are the options?" Its just 'stupid' to pay for a tuner. Why not buy a monitor without a tuner? We have discovered that most DVR's and the few VCR's now available don't have tuners in them so that seems to be the direction things are going.

I told Gracia that I will get her a digital box from Comcast, but she doesn't want another piece of electronic equipment with another remote control. A new TV set doesn't seem to be adequate for Cable service.

Comcast told me that it wasn't their decision to go digital, but the FCC's requirement. I went to an FCC Internet site and their Q&A said that the digital edict was only for over-the-air communications and the Cable Companies can do what ever they want. I think that Comcast will continue to provide analog signals even after February 2009, but I don't know. We still get those analog signals with our digital service.

Please let me know if you have any questions, comments, or new information. Thanks.

Subject: Converting to Digital Television

Hi John,

At the last PC Club meeting, you gave some information on your conversion to digital television with Comcast using non Comcast hardware and the problems that you encountered..

I would like to add your experiences to my page on Converting to Digital TV at http://www.sjpc.org/presentations/digitaltv.htm

I would appreciate it if you could describe in detail the hardware devices you used, hardware costs, how you connected them, the functions that worked successfully, and functions that did not work without Comcast's set top boxes.

From what you said at the last PC Club meeting, it appears that you were having trouble identifying channels because of a lack of a Comcast program guide.. Also, with the non Comcast DVR, were you able to record shows either manually by channel number and time or off a program guide? If you were to start over, would you consider leasing equipment?

My AT&T Dish 200 channel four room setup with a 350 hour SD or 55 hour HD capacity DVR works great and has all the TiVo functions such a recording two shows and watching a recording at the same time as well as pausing live TV. I had no installation or equipment costs, and my cost is about $58 a month including taxes and fees which is less than the $60.51 that I was paying for Comcast analog extended basic which had no DVR.

Thanks,

Russ.

Hi John,

Thanks for putting forth the effort to document your experiences with using a non Comcast digital to analog converter and a non Comcast digital video recorder with Comcast cable TV. I added your email to http://www.sjpc.org/presentations/digitaltv.htm at the end for now. I will try to better organize the page content at http://www.sjpc.org/presentations/digitaltv.htm when I get a chance.

Initially, I started in the same direction that you took and looked into hard disk DVR's that did not have a subscription fee. Fortunately, I took Alan Baker's advice which was to make sure that the DVR that I chose had a good program guide such as TiVo. I looked into TiVo, and I liked everything about it except for the subscription fee which was $16.95 per month on an monthly basis when I was evaluating TiVo. When I found out that Dish Network offered a subscription DVR with TiVo functionality and a 350 hour SD (55 hours HD) recording capacity for only $5.99 a month with no purchase or installation charge, I decided to have AT&T Dish four room system installed.

It appears from what you wrote, trying to use non cable or non satellite company hardware (except TiVo) is a "barrel of snakes". My suggestion would be not to invest any more time or money in non cable or non satellite company hardware and lease a DVR from a cable or a satellite company or buy a TiVo. I suggest that you see how easy DVR programming is with TiVo, Direct TV, and Dish Network by viewing their operation. At present, the Comcast DVRs have not been upgraded with TiVo functionality in the San Jose area, but you still might want to see the Comcast DVR in operation. You and Gracia are welcome to drop over to our home and see how AT&T Dish programming works.

The following was extracted from http://www.avsforum.com/avs-vb/showthread.php?t=987843 which seems to point out the difficulties of trying to avoid subscription fees.

Question: Should I be able to receive local HD programs (or any others ?) without purchasing a Comcast Box or subscribing to their Digital/HD program packages ? I believe the TV set has the QAM Tuner that folks have mentioned.

On many but not all cable systems, the local network affiliates and perhaps a few other "freebies" are carried on the cable in "clear QAM". If your set is QAM-capable, you can find and watch these channels by connecting the raw cable signal from the wall (or a split of it) directly to you sets antenna input, and then doing a scan. Consult your sets manual to find out which antenna jack, if there is more than one, and what settings in the scan menu might be needed.

Don't be surprised if the set finds hundreds of blank channels; those are the ones that are coded for conditional access (encrypted), but you should find your locals that way. Your scan will probably also find most or all of the SD analog "legacy" channels in the range of 2-80 or so. QAM channels carrying digital SD and HD programming typically run from about 80 to 125 or so.

Also don't be surprised if the set-indicated "channel" is an unintuitive number like "103.58". That is usually the raw QAM channel (e.g. 103) and the subchannel (e.g. 58) which unfortunately bear no resemblance to either the over-the-air or CATV STB channel number. You may then have to manually delete the unwanted blank channels, or move the usable ones into a "favorites" area for more convenient tuning.

A few enlightened cable systems pass through or add metadata that will identify the source or "real" channel number, but so far that's not common. They'd rather rent you a digital/HD STB which will map the QAM channels to a number that corresponds to their published lineup.

I have a TV with ATSC,NTSC and QAM. I want to use the TV tuner instead of the STB. Is there a CableCARD reader that is not a Tuner. Something that will decode the signal from the cable company and then my TV's tuner will pick it up. That way I just need one remote. I also installed a A/B switch to go back and forth from Cable and OTA. What you're asking for does not exist, and is not technically feasible due to the way CableCARD works. It's not a disk/memory card; it's a streaming decryption engine, which the captured bitstream has to be run through to yield an unencrypted stream which can then be fed into the appropriate decoding/display logic. The closest thing would be either (a) a TiVo Series3 (now discontinued) or TiVo HD DVR (which involves a monthly fee), or (b) Sony's DHG-HDD250/500 DVR (also discontinued). Far as I know, there aren't any other widely-available CableCARD set-top box devices, other than the cable company boxes - given that was the intent of CableCARD (to make anyone's box able to receive digital cable), it's a little bit funny.

Subject: Mapping QAM Channels


Hi John,

Since you asked for feedback, I will mention a few more things to consider.

You wrote "I told Gracia that I will get her a digital box from Comcast, but she doesn't want another piece of electronic equipment with another remote control. A new TV set doesn't seem to be adequate for Cable service." Why not just replace your OEM receiver set top box with the Comcast receiver set top box you are entitled to at no cost, and store the OEM receiver set top box for now? This would solve the mapping problems and not add to the clutter.

You might want to spend this year experimenting with a Comcast receiver set top box which is included in your Digital Starter package and/or a Comcast DVR which would cost $13.99/month plus any fees and taxes. Since you are paying only $30/month (plus fees and taxes) at present, it would only cost you $43.99 (plus fees and taxes) to try out both of these during your $30/month period. With either a Comcast receiver or a Comcast DVR, your mapping problems are eliminated.

If Comcast continues to increase rates once or twice a year (as done in 2007), your cost at the end of the $30/month period may be higher than $56 per month plus fees and taxes of about $4.50 which totals about $60.50 at present rates. My four room 200 channel AT&T Dish system with a DVR is only about $58/month including fees and taxes. To get a setup equivalent to mine (except the DVR capacity would be much less) from Comcast would be about $92/month plus fees and taxes.

You wrote " After getting digital service, I expected channels on my digital tuner devices to change, but saw no change in numbering and we still had the sub-channels". From what I have read, I believe that the Comcast transmissions to your home are the same for all levels of service, and the Comcast set top box has the logic to enable and disable channels to match your subscription. This is why you noticed no difference using OEM (non Comcast) equipment. With Dish Network, they also do it in the set top box by sending commands.

I changed the page at http://www.sjpc.org/presentations/digitaltv.htm to include links to all the topics at the top of the page. This make it a lot easier to find topics of interest.

The following was extracted from http://www.highdefforum.com/showthread.php?t=25525 which explains some of the aspects of QAM mapping.

Russ
--------------------------------------------------------------------------------------------
Is there some information source available that maps the 2 sets of channel numbers?

Qam = quadrature amplitude modulation. it is the carrier that brings the video/audio/digital info to your home via coax systems.

Each carrier is 6mhz. Wide and depending on the type of Qam it is (16,64 or 256) it is capable of holding up to20 channels.

I'm shocked that all these channels are unencrypted. The HD and movie channels are encrypted, but it seems all the extended programming channels (about 70 channels) are not!

AS far as the odd 87.1 channels being mapped to the cable ones, in my area they routinely change freq so what may be 87.2 today, may be 107.1 tomorrow. I got tired of scanning every so often. Using a company box, you never see this as the box gets remapped.

In my 3-year experience with a TV with a QAM tuner, here is what I have realized:
The QAM is responsible for converting the digital signal for your tv, simply having the HD tuner is not enough. You should get all of the local channels in HD regardless. The bonus is the music stations, other movie stations, and the "on-demand" content. I used to get ESPNHD, ESPN2HD, and few others, but they eventually went away. Getting the on-demand content only works when someone (probably on your box network) orders the show. I tested this out recently, and it worked. I got a (cable company) digital box for another tv in my house, ordered a movie, and then checked my TV with the QAM. The show came on. I check every once in awhile for new channels to emerge, but nothing much recently. As for the free HD local channels, they should come through to the channel based upon your local broadcast. For example, if NBC is channel 4 (over the air), then your NBC HD station should be 4-1.

There used to be a site that listed the lineup of the QAM channels for different cities, but I think the site went down. Someone should start one up again. I might.... I'll keep you posted....

This might be the site you're thinking of.

Subject: Comcast cable card


Hi John,

At http://www.comcast.com/Customers/FAQ/FaqCategory.ashx?CatId=301, it states the following.

"Comcast is committed to supporting digital-cable-ready television sets and other devices, such as the TiVo Series 3 HD set-top box and the Microsoft Digital Cable Tuners that consumer electronics manufacturers are developing. By offering Cable CARD services, we're able to provide choices: customers who prefer not having a digital set-top box can use a Cable CARD, while customers who want to use the full-range of Digital Cable features, e.g. ON DEMAND, Pay-Per-View, and the Comcast On-Screen Program Guide, will continue to use the set-top box provided by Comcast to receive those features."

You might want to go to all the links at http://www.comcast.com/Customers/FAQ/FaqCategory.ashx?CatId=301

It appears that the only way to get the Comcast program guide is to have a Comcast set top box or a set top box that has a Comcast cable card installed such as TiVo.

There is also a interesting article at http://www.tivocommunity.com/tivo-vb/showthread.php?t=382443 which states the following about scrambled channel mapping..

"I just went through a horror story with my HD TiVo (Comcast in Albuquerque NM), which now appears to be resolved, and wanted to share the experience and resolution with other TiVo users.

My TiVo HD has been working just fine. Yesterday while switching channels, the TiVo crashed, and rebooted itself. When that was done, I thought everything was back to normal, but it was not. All of my channels were remapped -- what should have been my NBC HD channel was now analog MTV, etc. I was getting black screens on analog network channels.

I ran through the Guided Setup but again nothing.

I called TiVo and they attributed the problem to the Cable Card, and suggested I call Comcast and have them 'hit' the card again. Sounded reasonable, so I did that. It didn't work. Comcast hit it several times -- no luck. So we scheduled a Comcast technician to come out (fortunately at 9 am the next morning).

The technician tried sending a hit to the card -- nothing. We removed the card and reinstalled it, did Guided Setup, again nothing. He installed a brand new card, we did Guided Setup, again the same result.

I should mention that across all of these attempts, while the channel mapping remained scrambled, it was CONSISTENTLY scrambled -- what should have been NBC HD remained as MTV, etc.

At this point the technician gave up and said he'd huddle with his lead engineer, who knows much more about Cable Card issues.

I decided to try TiVo tech support once again. The nice lady there noticed that my service was set to "Basic Cable" instead of "Digital Extended" so we reset that, and ... did the Guided Setup again (lord that takes a long time!). I was convinced this would fix it, but nope. Exactly the same situation, scrambled in exactly the same way.

So I called TiVo yet again. This time the tech support man suggested taking the Cable Card out and checking to see if I could get regular analog channels where they were known to be. I had no idea I could do this. So I removed the Cable Card, tuned to a known analog channel (one that I had NOT been able to receive while this problem was going on), waited for it to acquire the signal, and ... voila! It did receive the channel. In fact, all my analog channels were back to normal. TiVo tech support then said to call Comcast, since it was clearly a Cable Card issue.

So, I reinserted the Cable Card. It was recognized but didn't function properly. I called Comcast to have them come out again, and while I was online I asked the tech support person to just 'hit' my card one more time.

And guess what ... everything is now back to normal.

I think I hate Cable Card technology.".

Image Retention on a LCD Screen
 

There was an article in the San Jose Mercury News Business Section on May 5 on image retention (sticking) on LCD TV screens that caught my attention since we have an LCD HD TV.  Since many of us either have an LCD HD TV or plan to get one, I thought I would pass on the information that I found on that subject.
 
Image sticking is an intrinsic behavior of TFT LCD panels. It is the result of their susceptibility to polarization of the liquid crystals inside the display panel when a static image remains displayed on the screen for too long.

 

Many are aware that if you leave a static image for a prolonged period on a plasma TV, you may risk phosphor burn-in. The result is that
once you remove the static image, you would still be able to see a faint outline, or ghosting of the original image, even when you change
the picture content.  LCD TVs do not suffer from burn-in, yet as surprising as it may seem, they still suffer from image retention when a static or semi-static image is left displayed on the screen for too long.
 
In home entertainment applications, many do not realize that prolonged presentation of those vertical or horizontal gray or black bars, say when viewing 4:3 (non 16:9 HD formatted aspect ratio) program content over a wide-screen LCD panel, is also a form of semi-static image. These should be avoided by choosing an aspect ratio or zoom setting that expands the image to fill the whole screen area.  With my Dish DVR, I can use either the Stretch" or "Zoom" to fill the screen.  Although the "Zoom" clips the top and bottom of the picture to fill the screen, I prefer it to the "Stretch" which distorts the picture and makes people look heavier.
 
Similarly, try not to pause a picture on your LCD TV for too long, nor allow station logos, program menus, etc., to remain still on the screen for an extended period. If for some reason, you need to pause a film or a show to do something else, it is better to turn off your LCD TV set. True that a few minutes in this state would not do any harm, but what if you forgot all about your TV after having say answered a phone call?
Since many of us now have digital video recorders (DVR's), it is easy to pause live TV for up to an hour or pause a show recorded on the DVR, and this will leave the same static image on the screen for a prolonged time.  Therefore, it might be better to press the "Pause" key on the DVR remote, and then turn off the TV if you are pausing for a long time to answer a phone call or do something else. 
 
Most of the above was extracted from the article at http://www.practical-home-theater-guide.com/image-sticking.html   The full article gives a great deal of information on the cause of the problem, fixing the problem, and avoiding the problem of image retention, and the full article stripped of graphics to reduce the size is attached in PDF format. 
 
This following is the article that was in the San Jose Mercury News.
 
Fixing image retention on LCD TV screen
CHECK OUT SHARP'S REPLACEMENT POLICY
By Don Lindich
San Jose Mercury News Article on Maay 5,2008 from
McClatchy-Tribune News Service
Article Launched: 05/05/2008 01:35:12 AM PDT
 
 Q. Last year I bought a 42-inch Sharp Aquos LCD and have loved it. I recently noticed there is a dark half-inch vertical band that corresponds with the right edge of standard 4:3 TV images. Since we purchased the extended warranty, we contacted Best Buy, which sent a tech from a third-party firm. He pronounced "burn-in, not covered" and left. When we contacted Best Buy a week later they informed us that our extended warranty did not cover "any picture quality issues."
 
I understood that LCDs are not susceptible to burn-in like CRT and plasma sets, and the "persistence" issues of LCD pixels would go away when normal image viewing resumed. This has not happened and I am stuck with the dark band.
 
I'm very angry because the representative at the customer service counter convinced us we really should get the extended warranty because it covered "everything" - except possibly my taking an ax to the screen. Am I out of luck here?
 
A Your experience perfectly illustrates why I usually recommend readers shun extended warranties, especially on items such as flat-screen TVs. Not only are the warranties horrendously overpriced, in the event you actually need to use one, the problem may fall under a "not covered" loophole. As you see, not only have you wasted money, it makes you feel personally violated.
 
Best Buy is well within its rights, as I don't know of any warranties that cover burn-in, though strictly speaking that is not what you
are dealing with here. More damning is the fact that the tech could have done something about your situation, but didn't even try. You may want to seek a refund of the unused portion of your warranty.
I have frequently discussed the benefits of independent retailers, so to compare I contacted Digital Visions of Pittsburgh, a television and home theater store that has its own repair technicians. They got back to me right away and said LCD image retention is uncommon, but when it does occur, the following technique usually works for them and fixes it.
 
First, put your TV on the ANT (antenna) input and tune a non-existent channel so you have bright white "snow." Turn the brightness up all the way and let the TV play the snow for 4 to 5 hours. You can rub the affected screen areas very softly with a microfiber cloth to help the unsticking process.
 
This may be enough to unstick the pixels for you, but it is unnecessary as I have some good news. I did a little extra research on your problem and found that whenever Sharp TV owners experience image retention, Sharp USA goes the extra mile to take care of them. Encouraged, I contacted Sharp's PR department on your behalf and they put me in touch with their customer care department. Though you are out of the factory warranty, Sharp is going to send someone to replace your set free of charge and take away the old one. It should be in your living room by the time this hits your newspaper.
 
By the way, don't think Sharp is doing this is because a newspaper columnist contacted them. It seems to be their standard operating procedure. Hats off to Sharp!
