Error control for H.264/AVC video streaming

In recent years, the development of network and multimedia technologies has increased the demand for video delivery over various types of networks, such as the Internet or wireless networks. However, video delivery over packet-based networks poses several challenges, such as packet loss protection, limited bandwidth, and limitation on the maximum allowable delay. This thesis focuses on developing different error control techniques for video streaming over various networks to combat these challenges. First, we focused on developing a new two-stage encoder structure, which enables motion-compensated predictive encoders to have real-time Reference Picture Selection (RPS). In the second part of this thesis, we developed a novel noncausal whole-frame error concealment algorithm. Finally, we studied error control for multicast video transmission. We developed a subset selection scheme based on Type-II hybrid ARQ/FEC, which chooses video packets to be protected based on their influence on the decoded video quality.
