What is ATSC standard and how does it compare with NTSC standard?
ATSC is a set of standards developed by the Advanced Television Systems Committee for digital television transmission. ATSC replaced much of the analog NTSC (National Television System Committee) television system in the United States on June 12, 2009. On that day, all full power television stations in the United States started broadcasting in digital only. Digital television enables sending and receiving of moving images and sound by discrete/digital signals, comparing with analog signals used by analog television system. As the result, digital television produces higher quality image, sound and more programming choices than analog.
