What is HD?

You have to be careful using arguments like this: HDTV bandwidth is the same as same as old analog bandwidth. That's because of compression. The fact that you can fit four SDTV programs into the same space is also because of compression. Also, Broadcasters are continually adding new equipment. The switch to Betacam from film twenty years ago was to same on costs. We've since moved from Betacam to BetacamSP and now to Betacam SX. It all gives lower cost or greater flexibility, the same thing. A lot of cameras are now convertible from 4x3 to 16x9. Even if they don't record in HD, the quality is such that upconversion is less of a problem than you would think. Canadian broadcasters are well on the way to full HD and the addition of a relativly minor piece of gear like a cable box or satellite tuner won't get in the way. DVD watching is already driving the move to HD ready sets even without HD-DVD.

Default Progressive/Innerlace Scan

I have about 15 OTA dt stations and only two broadcast Pscan, one is fox (720p 16.9) and ABC (720p 16.9) the rest (1080 I 4.3 16.9) can't tell the difference...I have a Sony LCD projection TV and both formats are outstanding..I have a Radio Shack $24.00 UHF OTA antenna and dishnetwork with HD...I live 54 miles from the tranmitters and receive a great signal...Of course the transmitters or on Mount Wilson in So Calif, which may make a difference..

Don't confuse display resolution with broadcast resolution. HDTV broadcast formats will continue to be 720p and 1080i.

There is no such thing as an interlaced display with any non-CRT technology (that is, DLP. LCD, Plasma, and LCOS). Therefore, the only way a DLP, LCD, Plasma, or LCOS display can present a 1080i broadcast in native resolution is to take the broadcast, deinterlace it, and display it on a 1080p monitor.

My guess is 1080p will be the preferred format for BluRay and HD-DVD media, just like 480p is the preferred format for DVD media. This should produce absolutely stellar, super crisp, film-like pictures.

Also, 720p broadcast HD will upconvert to 1080p with simple scaling, as opposed to scaling and interlacing, which is needed for upconverting to 1080i. 1080i broadcast HD will only require deinterlacing.

The arrival of 1080p microdisplays (DLP, LCOS, or LCD projection) should drive down the price of 720p microdisplays to the price points of CRT projection displays today. And that should force HD CRTs even lower. This should increase adoption which will be good for the HD industry.

These new displays are not only 1080p, they're 60 frames per second... so upconversion of 720p preserves the quality of 60 fps motion. 1080i/30 will need deinterlaced & frame doubled... and may use sophisticated processing to generate these 'tween' frames.

So these new TV's will create new frames to fill in the empty frames left by the interlacing to maintain the 60fps? What if in the future a native 1080p60 signal is fed into the TV, I guess it won't have to create new frames?

Default My own take & some observations:

I've been standing on the sidelines, drooling for HD ever since I first read about early Japan efforts (in the early 1980's). I've watched the industry evolve. I have been in the HVAC sales business and frequently visited customer homes here in the So. California market. I have observed how TV habits have evolved, and boy have they been evolving. This past two years has been the most profound. These are not hard statistical numbers, and I am dealing with middle-income (and higher) families, but the neighborhoods ranged from below average to upscale. The revolution is on, new sets in homes abound, large screen sets are the most popular, and I've been amazed at how many HD home theaters I've seen in just the past year. Some have been quite clever, hiding the projector in an air conditioning register and an automatic powered screen. Mostly, I am seeing Plasma, DLP, LCD and rear projection tube sets, and some HD CRTs. The larger screens are really popular. While my business was air conditioning, I usually found time to query the homeowner re: their thinking on HD. I have also queried salespeople at stores.

I know we are at a crossroads, but the Europeans have just announced a fast-track process to launch HD so they won't be left behind. I can see that EDTV sales are doing well, indicating that some of public just doesn't get it. Many want the Plasma-look without getting the big buck bang. To be fair, a DVD on an ED looks far better than analog broadcast, so people like the package and the price.

Regardless of what Canada does, the N. American market is driving HD. I had a chance to live with a Sony Plasma 42 at sister's house in Coronado for a week, house-sitting. I enjoyed the set and the HD programming, but found that there is far too little of it. I was amazed at how bad the anolog channels reproduce on this HD screen, far worse than they look on a standard TV. But the HD programs were fun to watch.

I see the big danger as SDTV. I believe the government is too lax on the broadcasters, and sets policies which will help them to find the lowest common denominators. It is quite possible we will have these high end sets and that broadcasters will want to send out ordinary resolution content most of the time. I am hoping that the public gradually demands HD programming. I know that I would gravitate toward HD content, if and when I get a decent receiver.

My own thinking: I don't want to spend an arm and leg. I can see values in 720p DLPs with upconversion to 1080, and I can see the technology keeps improving. I can get into the game now, see reasonably pretty pictures and invest again in 4 or 5 years when there is a clear direction where the industry is going. It would be better than EDTV, and would be a bargain for my home theater room which I am setting up. It would not be the best, but would cost less than half what I might otherwise spend, and I could be done with analog at least in one room of the house. I am not of a mind to sink $5K or $8K-$10K into technology which is governed mostly by the marketplace, broadcasters who do everything they can not to comply, set makers who won't get their act together with standardization policies, and an apathetic public.

In spite of all that, I did want to report that I saw a HUGE number of households with HDTVs while I was working (I have just retired). Eoropeans are not going to be left in the dust, and neither are Canadians. I think HD is here to stay, but I worry that content may too often be SDTV.

I'll add my two bits in, as well.

I visit a large number of renovated homes while shooting for several national cable programs. Two years ago, we observed almost no HDTV sets, even in high end housing...most sets were older large projection SD sets.

Just last year, we started seeing many more HDTV sets in the home theaters. This year, just since February, the majority of the homes now have one or more HDTV sets...mostly plasma or LCD. Last year, the homeowners were bragging about upgrading to HD. This year, it's almost normal, and they don't seem to think it worth mentioning.

Almost everyone homeowner I ask, though, says there's not enough HD programming yet.
