| Another benefit of HDTV/DTV that hasn't been mentioned yet (at least to this point in the thread) is the ability to multicast on one channel. I.e. you don't have to use all of the bandwitch of a specific channel for HDTV content. You can broadcast 2, 3, 4 different programs on the same "channel". On an HDTV I saw recently, channel 46 was the normal OTA analog channel. The TV picked up 46.1, 46.2, and 46.3. Each .x program was different but broadcast in standard definition so you effectively had 3 channels rolled into the allocated space of one.
This works great if for instance a network program gets pre-empted by a sporting or political event. Assuming the broadcast station supports it, you could continue watching your regular show.
