Advanced Television Systems Committee
Introduction
The Advanced Television Systems Committee (ATSC) is an international non-profit organization that develops digital television standards. The ATSC standards are used by broadcasters across North America, South Korea, and other countries worldwide. The ATSC was formed in 1982 by the FCC and the NAB to establish a set of standards for the transmission of digital television signals.
History
The ATSC was established in 1982 to develop voluntary standards for digital television. The committee was formed by the FCC and NAB after the FCC called for a group to create a standard for digital television. The ATSC's first task was to develop the ATSC digital television standard, which was adopted by the FCC in 1996. The standard was later revised in 2009 to include mobile television broadcasting capabilities.
ATSC Standards
The ATSC has developed a series of standards for digital television transmission and reception. These standards include the ATSC digital television standard, the ATSC mobile DTV standard, and the ATSC 3.0 standard.
ATSC Digital Television Standard
The ATSC digital television standard, also known as ATSC 1.0, was the first standard developed by the ATSC. This standard defines the format for over-the-air broadcasting of digital television. The ATSC 1.0 standard includes specifications for video, audio, and data transmission, and is used by television broadcasters in North America and South Korea.
ATSC Mobile DTV Standard
The ATSC mobile DTV standard, also known as ATSC-M/H, was adopted by the ATSC in 2009. This standard allows for the broadcasting of digital television to mobile devices, such as smartphones and tablets. The ATSC-M/H standard includes specifications for video, audio, and data transmission, as well as for the use of interactive services.
ATSC 3.0 Standard
The ATSC 3.0 standard, also known as Next Gen TV, is the latest standard developed by the ATSC. This standard allows for the broadcasting of ultra high-definition television (UHDTV), high dynamic range (HDR) video, and immersive audio. The ATSC 3.0 standard also includes specifications for advanced emergency alerting, interactive services, and targeted advertising.
Future Developments
The ATSC is currently working on the development of new standards and revisions to existing standards. These include the ATSC 3.0 standard, which is currently being rolled out in the United States, and the ATSC-M/H standard, which is being revised to improve mobile television broadcasting capabilities.
