This article describes test and measurement applications as seen by the television engineer from basic analog television to the transmission of multimedia over telecommunications paths. Emphasis is placed on compressed data, which is becoming a predominant factor for audio and video. Although there are many useful compression algorithms, MPEG-2 appears to be the most universal, along with its very complete and widely accepted system definition for the transmission of all the data encountered in multimedia applications. The MPEG-2 transport stream, with its small packets, was developed for transmission systems and can be used to carry all types of data. The discussion outlines a layered model for systems and testing analogous to the OSI model for communications systems. Following a description of MPEG-2 transport streams, specific test methods for analysis and generation are discussed.
