Abstract
Wireless access to continuous-media services such as video, voice, and audio is becoming increasingly prevalent. Interactive video services such as video conferencing and multimedia editing are two such services of particular interest. We discuss some of the problems with using the MPEG standard (which was designed for wired, circuit-switched services) for wireless packet-video transport in a mobile environment. We propose a novel strategy for video transport using a layered source coder in conjunction with a variable QOS, multiple-substream abstraction for the transport. This abstraction addresses specifically the need to obtain simultaneously high spectral efficiency, good subjective quality, and low perceptual delay on a wireless channel. It also addresses the heterogeneous transport resulting from the concatenation of a wireless access link with a broad-band backbone network.
