ATSC Standard

From Wikipedia

The ATSC standard was developed by the Advanced Television Systems Committee (ATSC) as a digital television format to replace the analog NTSC television standard in the United States.

The high definition television standards defined by the ATSC produce wide screen 16:9 images up to 1920x1080 pixels in size – more than six times the display resolution of the earlier standard. ATSC signals are designed to use the same 6MHz bandwidth as NTSC television channels. However, many different image sizes are also supported so that up to six standard-definition "virtual channels" can be broadcast on a single 6MHz TV channel.

ATSC also boasts "theater quality" audio through the Dolby® Digital AC-3 format, providing 5.1 multi-channel sound.
