[quote=spdrun]It’s well known that over-the-air HDTV has better definition than cable — cable is known to be lossily compressed.[/quote] OTA transmission also uses a lossy compression algorithm too. Cable actually has more bandwidth than OTA and less interference. OTA HDTV is both better and worse quality compared to cable. The primary channel seems to be better quality, secondary channels seem to be worse. It also looks like the key frames (I-frame) of the video occurs less frequently in OTA than cable. This shows up as channel switching occurring slower on OTA compared to cable.
