Coding multiview video content often benefits significantly from disparity compensation. More advanced inter-view predictions, to predict e.g., motion vectors and residues among views require disparity vector to identify blocks in different views corresponding to the same objects. Block-level disparity vectors in typically approaches are either transmitted thus with additional overhead, or predicted...
In the multiview video plus depth (MVD) representation for 3D video, a depth map sequence is coded for each view. In the decoding end, a view synthesis algorithm is used to generate virtual views from depth map sequences. Many of the known view synthesis algorithms introduce rendering artifacts especially at object boundaries. In this paper, a depth-level-adaptive view synthesis algorithm is presented...
Feedback-based error-resilient video coding relies on efficient transmission of feedback messages. The Audio-Visual Profile with Feedback (AVPF) for Real-time Transport Control Protocol (RTCP), i.e. RTP/AVPF, supports low-latency feedbacks. In this paper, a reference picture selection (RPS) method using RTP/AVPF-compliant feedback is proposed. A restriction period is first derived in the codec layer...
Bi-predictive (B) slices are not supported in the baseline profile of the advanced video coding (H.264/AVC) standard, which results in a decreased coding efficiency compared with other profiles supporting B slices. However, many application standards, such as the mobile multimedia services specified by the Third Generation Partnership Project (3GPP), use only the baseline profile for H.264/AVC. Therefore,...
