Abstract
Novel 'loss rate' metrics are presented that can be used to indicate the quality of a video stream. These metrics may be determined using a simplified method or by a more sophisticated method, the latter method applying different 'weights' (i.e., adjustments) to error computations based on the type of frame involved (i.e., I, P, B). Both methods may produce a video quality score within a given range (e.g., in the range of 0 to 1) where one end of the range indicates a video stream of high quality (i.e., no frames are affected), and the other end indicates a video stream of low quality (i.e., all frames are affected).
