Coding of Full Motion Color Video Signals at 50 KB/S.

摘要

This report describes a video coder operating at 56 kb/s or 64 kb/s. The coder was designed for possible use in the proposed National Command Authority Teleconferencing System. The system provides multisite, multimedia conferencing. It assumes one participant per site. Under certain conditions, availability of communications bandwidth can be drastically lowered. This report presents the coding algorithm for operation at 56-64 kb/s transmission bit rates. In this case, a capacity of 50 kb/s is allocated for the video information, while the remaining 6 - 14 kb/s is reversed for framing, error control, and other overhead.
