Transport issues related to contemporary cell-switched audio/video traffic
Maurice R. Baker · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
This paper first examines several application areas involving transmission of audio/video content and some pertinent attributes. In the remaining sections, the technical focus is on the prevalent transport of MPEG-2 coded and packetized audio/video content over cell-switched Asynchronous Transfer Mode (ATM) networks. Particular emphasis is placed upon key aspects of interworking between the source coder/decoder devices and the transmission network along with the impact of transport-level impairments upon the resulting quality of service. Although the coverage is specifically oriented toward MPEG-2 over ATM, many of the issues examined should prove relevant to applications involving homogeneous packet-switched (e.g., Internet Protocol) transport or integrated architectures which leverage the respective advantages of cell and packet switching over a multiservice network.
