An error resilience scheme for layered video coding

Layered video coding combined with prioritized transmission is widely recognized as one of the schemes for providing error resilience in video transport system. We examine the error performance of data partitioning coded MPEG-2 video bitstreams transmitted over channel subject to bit errors. While base layer errors cannot be tolerated, only a limited amount of errors in the enhancement layer is acceptable. Further improvements on bit error resilience can be achieved using the EREC coder in the enhancement layer. Our results show the PSNR gain of up to 3 dB with EREC coded enhancement layer and no errors in the base layer.
