Abstract

Application layer forward error correction is becoming a popular addition to protocols for real-time video delivery over IP-based wireless networks. Since each part of video data is not equally important for video reconstruction, it is beneficial to divide video data based on its importance. Such partitioned data could then be provided with different degree of protection, with the important data having more protection against channel erasures. Data partitioning (DP) is one such low-cost feature in H.264/AVC enabling partitioning of video data based on its importance. In this paper, we propose an Unequal error protection (UEP) scheme to protect the DP H.264/AVC coded video data with Raptor and Random linear codes (RLC). The simulations have been performed using error traces which depict physical-layer Transport Stream (TS) packet losses in DVB-H. The results highlight that for broadcasting applications with varying channel conditions, better results can be obtained with dynamic probability of selection of different importance layers.
