Method and apparatus for reduction of compression noise in compressed video images

摘要

A video processing method and system that obtains, transmits, and processes digital video compression rate information between a video receiver such as a Set-top-box (STB) and a display device such as a TV set. The compression rate information is obtained by the video receiver and delivered to a compression noise reducer in the display device. The compression rate information provides an indication of how much compression noise might be embedded into an incoming compressed video signal and thus allows the compression noise reducer to reduce compression noise from the incoming video signal more effectively and efficiently.
