Video Testing in a DTV World
This paper describes the digital television system, its elements, and appropriate methods of video testing. A layered approach is defined including video, protocol, and transmission channel testing. With today's use of video compression there is still a need for traditional analog and full bandwidth digital testing methods. Compression systems require objective picture quality measurements of distortions caused by its nonlinear and time-variant digital processing. Test method terms such as in-service and realtime are defined for both video and protocol testing. The three internationally accepted system approaches to objective picture quality testing are discussed including the advantages and disadvantages of each.
