Essentially that is what DTV is. OTA (Over the air) here in the U.S. has 
a set amount of bandwidth. Enough for an HD signal, and several 
sub-channels. Most of the local network stations have their main 
channel, a weather channel, and a 24hour local news channel.

*Most* DVDs look quite nice. You'll still notice compression in fast 
action scenes, though, especially if the encoding was managed poorly.
