Abstract: This article discusses the general approach of objective and subjective evaluations on digitally compressed video. After a brief review of digital compression principles, the artifacts associated with video compression are identified, along with their origins. To investigate the usefulness of the conventional NTSC test signals and measurement procedures, both analysis and experiments were carried out, and observations are made based on these experiments. In addition, some new objective test signals and measurement methods are presented, and the application of these methods for assessment of compressed video is discussed. For subjective assessment, the design of testing is reviewed first; issues that may affect the success of subjective evaluation are discussed in detail. The importance of choosing critical test sequences is stressed and some guidelines on what kind of test material may be chosen are given. Finally, some new proposed methods and suggestions for performance evaluation are reviewed.
