Abstract

Based on the analysis of hierarchy and the significant characteristic of MPEG-4 bits stream, a novel robust joint source channel coding method is proposed for MPEG-4 video transmission over noisy channel. In the method, the base layer bits streams are reordered according to their relative importance and then interlaced packet. Multiple sublayers of texture information are generated based on their rate distortion function, which number is adjusted dynamically to minimize the overall distortion by the encoder according to the feedback information. The simulation results show that the proposed method is robust to packet loss and superior to the MDFEC scheme proposed by Puri
