Abstract

The emergence of H.264/AVC video compression standard provides better support functions for wireless network. The characteristics of limited bandwidth, high error rate of wireless channel and the constraints of computing and storage capacity of most mobile devices make the key technology of video codec in error resilience strategies, rate control, mode decision and scalable extension more important. In this paper, we first analyze the main and popular strategies in the key technology, and then we propose a method to choose and combine these strategies to validate the results and performance by experiment. Experiment shows the rational use of these technologies improves the quality of video transmission and provides reference for the video service evaluation.
