FORWARD ERROR CORRECTION FOR VIDEO CODING - A common solution

Antonio Navarro, João Tavares

Abstract

Joint source-channel coding solutions has proved to provided better performance than dealing with both coding processes separately. Such improvement is achieved by jointly minimizing at the source encoder the channel effects. In this paper, we present an adaptive scheme for forward error protection of any video coding standard. The channel coding rate changes according to the channel bit error rate (BER). The results are impressive. For instance, a PSNR gain of about 16.7 dB is obtained at BER=10-2 for “Foreman” video sequence, encoded either by H.263 or by MPEG-4 and protected using the Common scheme in comparison to the unprotected case. As our proposed scheme is common to all video standards, it obviously provides some video quality degradation but still acceptable. We have assessed the quality degradation of the Common solution in comparison to the optimal scheme of protection, which uses a finite number of channel codes. Additionally, we propose a protection solution tailored to H.263/MPEG-4 video coding with an average PSNR improvement of about 0.2 dB relatively to the above mentioned Common solution.
