scope:

This standard is the North American adaptation for Domestic-International interfaces of the ETSI ETS 300 174 standard for the coding and transmission of digital component television signal at a bit rate of 45 mbit/s. It provides a detailed description of the digital coding algorithm to be implemented in equipment designed to terminate digital transmission systems when those systems are employed to carry ITU-R 601-2 digital television video signals, AES/EBU digital audio signals and ancillary signals such as SMPTE time-code, and SMPTE machine control. Each television signal is formatted to be compatible with the North American DS-3 transport network. The video coding algorithms are based on a hybrid predictive/transform scheme incorporating arrangements for variable word- length coding (VLC), synchronization, and video framing. Provision is made for the transmission of audio and teletext services to accompany the video and for the application of scrambling for conditional access. Formerly known as T1.802.01-2001(R2006).
