Technology Group 1
The ATSC Technology and Standards Group, with due regard for existing standards organizations and activities, develops and recommends voluntary, international technical standards for the distribution of television programs to the public using advanced television technology. Technologies considered may be improvements to current systems or entirely new systems that are compatible or incompatible with current systems. All forms of distribution systems may be considered, such as terrestrial broadcasting, cable systems, direct satellite broadcasting, and pre-recorded media. With respect to distribution systems, sound, vision, display, conditional access, and data sub-systems may be considered.
