Executive Summary

Following the joint source and channel coding paradigm, the authors propose in this paper an application controlling strategy to allow fast adaptation of multimedia transmission to the impairments of an IP wireless network. To this purpose, a semi-analytical prediction algorithm of the video stream Perceived Quality of Service (PQoS) expressed as the End-to-End Distortion (EED) is introduced, that takes into account the distortions due to the diverse treatments of compression, transmission and decoding for a Group Of Pictures (GOP) subject to an imperfect communication channel.
