Multiple description coding (MDC) offers an elegant approach to data transmission over lossy packet-based networks. This paper proposes an MDC decoder for Compressed Sensing (CS) based MDC. Our decoder minimizes ??0 norm of the total variation of the image in a recursive manner, making it effective when different descriptions experience different time delays in the network. The proposed approach brings...
In this paper, we discuss a novel priority assignment and packetization scheme to transport H.264/AVC video packets over wireless networks. Specifically, we discuss a comprehensive packet priority assignment scheme for unequal error protection, followed by the use of adaptive network abstraction layer unit (NALU) sizes and NALU fragmentation schemes. These schemes use the standard-compliant decoder...
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...
