ATSC

ATSC (Advanced Television Systems Committee) is the high definition television standard that will replace the NTSC system currently in use in the North America. ATSC allows for the broadcast of high definition (up to 1920 by 1080) and wide screen (16:9) video along with Dolby Digital 5.1 surround sound.

ATSC signals travel over the airwaves in the same band as older television signals. However since many stations will broadcast in both standard and high definition, two broadcast channels are required. Many station broadcast the old analog and the new digital signal while consumers make the transition to digital.
