Abstract
In an error-prone communication channel, more important video packets should be assigned stronger channel codes. With various packet sizes and distortions for each packet, we use the subgradient method to search in the dual domain for the optimal RCPC channel code rate allocation for each packet, to minimize the end-to-end video quality degradation for an AWGN channel. We exploit the advantage of not sending or not coding packets of lower importance.
