Which means, cram as much info in the channel or storage medium as capacity permits, subject to the constraint that the channel or storage medium is compatible with ALL TVs! This will improve the quality of all TVs, small ones AND big ones. So, 480 at 24p is probably a good choice for a station wanting to multicast decent quality programs. But 480 at 24p is not a good choice for next gen movie DVD, as long these DVDs can hold an entire HD movie. What are you saving that space for? Another movie in the same disk? Does anyone care about that? Similarly, a station wanting to broadcast sports and attract a large audience of large screen fanatics will opt for true HDTV, like 720 at 60p or 1080i, for the duration of that game. A station wanting to multicast one good quality sports program along with an HD program will have to use 480 at 60p for the sports show, and may fit a 720 at 24p for the HD program. Or certainly they can multicast one 480 at 60p and one 480 at 24p stream. > There are many applications for progressive video > that is not HDTV. As long as you are *not* negotiating a unicast session over a relatively slow link, or otherwise limited in channel capacity, there's just no reason to limit the bitstream JUST BECAUSE you can do so.
