From Wikipedia, the free encyclopedia.
The Advanced Television Systems Committee (ATSC) is the group that helped to develop the new DTV standard for the United States, also adopted by Canada, and being considered by Mexico and other countries.
The ATSC standard uses Dolby Digital audio. It allows for the transmission of multiple channels of information per analog channel. For example, the UHF channel 35 might carry up to 4 standard-definition programs.
ATSC also allows for the transmission of HDTV (high-definition television) pictures which provide higher resolution and better color representation when compared to standard-definition or enhanced-definition signals.
