In this paper, a real-time CAVLC decoder for HD video is designed. The whole decoding process is controlled under a finite state machine with ten states. Due to variable length code, the five syntax elements will be parsed step by step. In the proposed scheme, we exploit a look-up table algorithm based on pos (the number of zero) and may be divided into sub-table according to priority in the same...
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...
Distributed multi-view video coding (DMVC) has become a focus due to the prosperity of the multimedia applications in wireless sensor networks. We propose a novel method of an adaptive scheme, named side-information-adaptive Low Density Parity Check (LDPC) coding. Apart from the existing multiple side-information implications in DMVC, this paper is dedicated to not only utilizing LDPC to produce the...
Synchronous audiovisual streaming and playout are two of the major issues in the multimedia communication network. However, the past corresponding researches of media synchronization mainly focused on the mono-quality and single-layer (nonscalable) audiovisual data. To overcome challenges of ubiquitous multimedia streaming, a scalable audiovisual coder that can provide flexible scalabilities and adaptive...
