Abstract
A picture quality monitoring system for a television chain provides incremental metrics for each layer of the chain--video, compression and modulation. The output of each layer is stored as a reference signal for the next or subsequent layers. The output from each layer is compared with the output from a prior layer to determine an incremental degradation metric. All of the incremental degradation metrics may be combined to produce an overall degradation metric for the entire television chain.
