SUBJECTIVE TESTING OF BROADCAST-QUALITY COMPRESSED VIDEO

This paper describes the analysis and subjective testing of broadcast- quality compressed video conducted by the Public Broadcasting Service (PBS) and the Communications Research Centre's (CRC's) Advanced Televi sion Evaluation Laboratory (ATEL). To fulfill the program objectives, a novel approach to test preparation and conduct was adopted. New meth odology was employed in the development of a reference model and in th e selection of test material. The tests were conducted under controlle d viewing conditions, using internationally recommended methods. Stati stical analysis was performed on the test results, and observations an d conclusions are given based on those results.
