The authors provide a description of research conducted with MPEG-1 and MPEG-2 compressed broadcast material transmitted in the presence of network impairment factors, in the form of payload bit error and cell loss. The study is different from other reported work in that it incorporates a complete user-perceived quality model, which takes into account the effects of concurrent impairments on both the audio and video streams of an audio-visual stream. The joint evaluation provides a more comprehensive model of user-perceived quality acceptance levels of broadcast audio-visual applications and as such provides valuable ATM network design data
