ATSC stands for Advanced Television Systems Committee. It is an organization that develops and establishes technical standards for the transmission and reception of digital terrestrial television (DTT) in the United States and other countries.
The ATSC standards define the system for transmitting and receiving digital television signals over the airwaves. This system allows for the delivery of high-definition television (HDTV) and other digital video and audio content to consumers.
The ATSC standards use a modulation technique called 8-VSB (8-level Vestigial Sideband) to transmit the digital signals. This modulation scheme allows for robust transmission and reception of the signals, even in challenging environments such as in urban areas with tall buildings or in areas with difficult terrain.
ATSC also defines the specifications for the video and audio compression used in digital television broadcasts. Common video compression formats used in ATSC broadcasts include MPEG-2 and more recently, H.264, which allows for more efficient use of bandwidth and higher image quality.
ATSC standards are widely implemented in television receivers, set-top boxes, and other devices that receive digital television signals. By adopting these standards, broadcasters and manufacturers ensure compatibility and interoperability between different equipment and systems.
In conclusion, ATSC is an organization that sets the technical standards for digital terrestrial television transmission and reception. Its standards enable the delivery of high-definition television and other digital content to consumers and facilitate compatibility across different devices and systems.
