Analysis of a method for improving video quality in the Internet with inclusion of redundant essential video data

This paper presents a variant of a method for combating the burst-loss problem of multicast video packets. This variant uses redundant essential video data to offer biased protection towards all critical video information from loss, especially from contiguous loss when a burst loss of multiple consecutive packets occurs. Simulation results indicate that inclusion of redundant critical video data improves performance of our previously proposed method for solving the burst-loss problem. Furthermore, probability models, created for evaluating the effectiveness of the proposed method and its variant, give results which are consistent with those obtained from simulations.
