Abstract :
This paper discusses a system test for digital DBS system with respect to audio and video signals. The test includes system delay, lip sync, service interruption time, audio quality, and video quality. The first three tests are implemented quantitatively, and the last two tests are implemented subjectively. The criteria for the system test are defined, its test methodology is discussed and its test results are analyzed
