Even if it is HDTV ... not all HDTV is equal. ABC and FOX broadcast 720p, while the rest broadcast 1080i. While 720p will generally give you less artifacts/pixelation/macroblocking, 1080i gives you better resolution. But even at 1080i you will notice a difference in PQ. Some of the stations are using older HD cameras. Some programs are downconverted from film to HD and some are shot with HD cameras. Also, some are widescreen SD upconverts, such as many of the nature programs on PBS. Also, on some sports telecasts, often not all the cameras are HD ... some are SD even though the picture is 16:9. I am sure that you are understandably a bit confused by all this!
As a general guide-
1. If the PQ is not MARKEDLY better than SDTV 4:3 images it probably is not HDTV.
2. Most programs broadcast in HDTV will indicate something like "HDTV where available" at the beginning.
3. Also, if you go to the web sites of each of the major networks (ABC.com, CBS.com, NBC.com, FOX.com) they indicate on their schedules which shows are broadcast in HDTV.
Some of the best for PQ are Smart Travels, The Desert Speaks, Great Museums and Tracks Ahead on PBS, The Tonight Show with Jay Leno on NBC and the best one in my opinion "HD to the Max" on CBS Boston (which is IMAX films downconverted to HDTV ... I say downconverted because IMAX film is of a much, much higher resolution than even 1080p).
WOW TV is here! NTSC RIP!
