This is a little something I have compiled from my days visiting the AVS Forums HDTV sections. I like to all ways keep this info on stand by for those occasions when someone might bring up HDTV outside of a Home Theater forum. So if you would please, give me some advice on what might need to be changed or revised. I am currently checking some of those links, because a few no longer work.


HDTV is part of the new digital television (DTV) broadcasting standard, which will replace our current system in 2006.

HDTV is a digital signal, unlike the analog broadcasts you're used to watching. A special decoder (called a set-top box or STB) is used to receive and decode the signals. These decoded signals are then connected to a TV set with HDTV-compatible inputs.

There are two HDTV broadcast formats: 720p (720 picture scanning lines, progressive scan like a computer monitor) and 1080i (1080 scanning lines, interlaced (alternating) like our current TV sets. You'll notice the incredible sharpness right away - you can see blades of grass and paint flecks in close-ups. You be able to read small logos and notes on clipboards, too!


HDTV broadcasts are 6 times sharper than SDTV

SDTV = 480 X 720 = 345,600 pixels

HDTV = 1080 X 1920 = 2,073,600 pixels

2,073,600 / 345,600 = EXACTLY 6

HDTV broadcasts are always widescreen, like widescreen DVDs

HDTV broadcasts are 'studio quality' - no snow, ghosts, or distorted


HDTV sound can be stereo, Dolby Surround, or Dolby 5.1

Most HDTV broadcasts are mainly on UHF channels

C-Band, Dish Network and DirecTV all carry HDTV

Time Warner Cablevision and a few other Cable networks carry HDTV programming in selected areas.


(CBS) - broadcasting 1080i

Most of the CBS prime-time schedule (19 I think) is broadcast in HDTV each night. Also special events, movies and sporting events are also broadcast in HDTV. Thus far this year CBS has broadcast the all AFC play-off games, Sony Open, Super Bowl, NCAA Final Four and the Masters in HDTV.

(ABC) - broadcasting 720p

ABC broadcasts several movies a month (Wonderful World of Disney and ABC’s Saturday/Sunday night Big Picture) and 'NYPD Blue' in HDTV & 5.1 DD. It is rumored that ABC will follow CBS lead and broadcast a majority of its prime-time shows in HDTV for the 2001-2002 season. They will likely bring Monday Night Football back to HDTV as well.

(PBS) - broadcasting 1080i

PBS transmits 2 - 3 new shows/documentaries a month in HDTV, plus several SDTV widescreen shows/documentaries. They also show HDTV Demonstrations regularly through out the day.

(NBC) - broadcasting 1080i

NBC carries 'The Tonight Show' in HDTV each evening. NBA Finals. ER will likely be in HDTV next season since ER is presented in widescreen this season.

(Fox) - broadcasting 720p

Fox does not broadcast true HDTV (720p or 1080i), but many Fox shows are in widescreen 480p. Fox is expected to show Star Wars Episode I in it’s OAR (original aspect ratio) and Dolby Digital EX this month.

(HBO) – broadcasting 1080i

about 80% of the movies on HBO is in HDTV. The rest are upconverted to HDTV (480i to 1080I) Most of HBO produced movies are shown in HDTV. The Soprano’s is broadcast in HDTV. The Bruce Springsting Concert this Saturday (4-7-01) will also be televised in HDTV and 5.1 DD.

(ShowTime) – broadcasting 1080i

ShowTime is currently only available on C-Band (I think), Dish Network and some Cable systems. I would say that about 65 to 70%of the movies on ShowTime are broadcast in HDTV. The rest are upconverted to HDTV.

(MSG-HD) – broadcasting 1080i

Madison Square Garden’s sports station shows the Knick, Rangers and Yankees home games in HDTV. But it is currently an exclusive to Time Warner and Cablevision in NY. It will be available for other cable and satellite companies in 2002.

(Fox Sports Net– HD) – broadcasting 1080i

Fox sports broadcast New York Islanders, New Jersey Devils, New Jersey Nets, and New York Mets home games in HDTV. But it is currently an exclusive to Time Warner and Cablevision in NY.

(Discovery) - broadcasting 1080i

The Discovery channel should have its HDTV channel up and running by the end of the year.

(Portland Trail Blazers) - broadcasting format is unknown at this time 720p or 1080i

Paul Allen and the Portland Trail Blazers have confirmed an HDTV Sports Channel which may be on the air as soon end of the summer. http://www1.nba.com/blazers/news/hdt...av=ArticleList

(Mark Cuban’s HDTV Sport Channel) - broadcasting format unknown 720p or 1080i

Mark Cuban founder of http://www.broadcast.com and owner of the Dallas Mavericks is also planing an HDTV Sports Network.

his upsides and downsides of HDTV
from dhackney

Upside news:

- There is actually quite a bit of HDTV content right now, on free broadcast as well as DBS

- Major events are in HDTV, i.e. NFL playoffs, Super Bowl, etc.

- The great standards scare is over, i.e. COFDM vs. 8-VSB; so people can buy tuners with confidence (not counting 5C copy protection issues/technology referenced below)

- Price points are dropping. We purchased an HDTV capable 61" set for ~$4k. Tuners can be had for $300-500. (Dish 6000 or RCA DTC-100)

- More tuners are available now, with second generation chips, from major manufacturers.

- There is no replacement for seeing the image in person. Make sure he visits a store or a home where he can see a real HDTV image, perhaps a HiPix owner who has some Super Bowl imagery recorded could volunteer to demo, or anyone who can pull in CBS prime time or Jay Leno.

- Sales of HDTV capable sets are accelerating. Check the ce.org site for the #'s. Solid growth rates. You can buy them at all the big box stores, i.e. Circuit city, Best Buy, etc. What the sales people lack in HDTV knowledge the chains make up for with increased volume. Bigger volume means lower costs for everyone.

Downside news:

- Big finger pointing war between broadcasters, FCC and consumer electronics industry for rate of adoption, rollout, etc. Mostly comes down to a chicken or egg argument regarding "we'll put out content when there's more receivers/tuners" vs. "we'll sell more tuners when there's more to watch"

- Battle's not over in the effort to wring out max revenue from HDTV spectrum. I think we'll see lots of multi-casting (multiple low res "channels" on one slot) vs. full resolution HDTV and data casting & low res. vs. full resolution HDTV

- Battle has not even begun on the "pay button" scenario. Very strong chance that the only way we'll be able to view full resolution HDTV is to pay per view, pay per record, pay per playback. All this on spectrum that the public owned and gave them for free, but, that's another discussion...

- Public is completely unaware of the implications of the new digital standards that will allow media Intellectual Property (IP) owners full control of the full life cycle of the IP content. The technology standards that are part and parcel of the HDTV world allow the content creators and distributors (cable, DBS, etc.) to monitor, track and analyze everything about the content utilization. This means they will know what you watch, when you watch it, how you watch it, when you record it, when you play it back, how you play it back (what commercials you skip, etc.) It's the ultimate "market of one" enabling technology for them. This data set will probably be more valuable than what they'll make by charging you for each viewing, recording, etc. They'll sell it to the marketers, ad agencies, etc. who are trying to figure out the best way to reach you and how much they should pay for ads.

- and, uh, BTW, you can't take the HDTV (IP content protected) tape of the game over to your buddy's house to watch it, there's no sharing of content between devices unless you bring along your personal identity along, i.e. your deck's smart card to put into your buddies compatible deck. (Oops, I forgot that there are no standards for that kind of thing in the US market, you'll have to carry a variety of smart cards, fobs, etc. for the plethora of standards & systems, see the cellular phone market if you're wondering what I'm talking about regarding lack of standards...)

- and forget about creating a collection of your favorite Friends episodes, if they allow taping at all (each piece of content carries a data flag that determines if it is "record none, record once, record X times, etc.), they're not going to allow multiple copies for anything of any value
