Abstract
Digital compression methods based on MPEG-2 are now widely used for broadcasting video content. Many television and radio programs can be multiplexed and transmitted together within the same bandwidth, where formerly only one analog program fit. Analog television video quality included the transmission chain and all the elements along the line; once a sufficiently high level was achieved, it was nearly independent from the content. With digital compression and transmission techniques, video quality is strongly content and compression-dependent and changes can be very abrupt from scene to scene. A means of following these changes in realtime and displaying picture quality, as a function of time, is required for continuous video-quality monitoring. This paper describes a single-ended quality analysis method that does not require a reference signal and is capable of processing video in realtime.
