An analysis modeling of frame-level forward error correction for H.264/AVC over burst-loss channels

Unequal error protection (UEP) on streaming media broadcasting is a widely used technique over wireless environment. Forward error protection (FEC) with UEP is a prevailing scheme to improve the quality of video streaming over lossy channels. Frame-level FEC have been proposed for video streaming due to the priorities of video frames within transmission constraint on Bernoulli channels. However, in current Internet architecture, various communication and storage systems are prone to corrupt as burst of noises occurs. The corrupted data pieces may exceed the error correction capacity of FEC, and therefore degrade the efficacy of FEC. To address this problem, we proposed a model to evaluate the perceived quality of H.264/AVC video streaming over burst channels. The experiment results indicate that the proposed scheme is able to evaluate the video streaming quality in perspective of decodable frame rate (DFR) with lower complexity than alternative methods.
