SYSTEM AND METHOD FOR GLOBAL INDICATION OF MPEG IMPAIRMENTS IN COMPRESSED DIGITAL VIDEO

摘要

A method of determining processing a coded video signal includes decoding the coded video signal; determining a global indicator value for a frame from the decoded video; and providing video processing to the decoded video of the frame based on the global indicator. Additionally, an apparatus for processing coded digital video signals includes a coded video decoder; a metric calculation module; and a video processing module, wherein the metric calculation module calculates at least one value of a global indicator, which indicates the quality of the coded video signal, and where the metric calculation module provides the global indicator to the video processing module, which selectively addresses the coded video signal depending on the value.
