Abstract :
A FEC coding strategy compatible with the H.263 standard is proposed, which uses unequal error protection to improve image quality for low bit rate video transmission over noisy channels. The H.263 bit stream is partitioned into classes of different sensitivity, without introducing any modification into the standard stream syntax. The experimental results show that the proposed scheme can be used either when video is transmitted over channels having high round-trip delay and limited bandwidth, or as a FEC segment of an integrated FEC-ARQ strategy
