Raptor Codes Based Unequal Protection for Compressed Video According to Packet Priority |
Abstract | ||
|---|---|---|
Raptor codes are state-of-the-art forward error correction (FEC) solutions for multimedia transmission, which have been applied to unequal error protection (UEP) of multi-layered media such as scalable video coding. In this paper, we address the problem of UEP for single-layered video over packet erasure channels. By exploiting the different priorities of video packets inside a group of pictures (GOP) and making full use of the good characteristics of standardized Raptor codes at large block length, we propose an optimized UEP framework for single-layered video and develop an efficient algorithm to solve it. Simulation results show that significant gains can be obtained by our method in case of packet losses. |
