Pattern selection for error-resilient slice interleaving based on receiver error concealment technique

Abstract

Video communication is often afflicted by packet loss over unreliable networks. To alleviate the quality degradation in the situation of packet loss, this paper proposes a novel error resilient slice interleaving method for compressed video packetization. Each packet is constructed by interleaving independently decodable slices of the coded video bit-stream in consecutive frames. The optimal interleaving pattern for minimizing the overall distortion of the decoded video, subject to a delay constraint, is determined based on the error concealment technique employed at the user end. Compared with traditional errorresilient methods, this scheme greatly improves the overall performance without requiring an increase in bit-rate. Experimental results on different video sequences demonstrate the effectiveness of the proposed approach.

Wireless Video Surveillance: A Survey

“…The main concept of MDC is to create several independent descriptions that contribute to one or more characteristics of the original signal: spatial or temporal resolution, signal-to-noise ratio (SNR), or frequency content [43]- [46]. For video coding, the subdivision is usually performed in the spatial domain or in the temporal domain, such as separating the odd and even numbered frames [47], the spatial chessboard MB decomposition [28], and the spatiotemporal slice interleaving [48]. The descriptions can be generated in a way that each description is equally important to the reconstructed content.…”

Error concealment algorithm using inter-view correlation for multi-view video

“…To deal with the problem in multi-view applications, many studies have been proposed. In general, error recovery can be undertaken by two approaches called error resilience [5][6][7][8][9] and error concealment [10][11][12][13][14][15][16][17][18]. For multi-view error concealment, study [17] uses the intra-view difference, inter-view correlation, and difference of the interview disparity vector projections on the neighboring views to conceal the error frames.…”
