Distributed videocoding is a new videocoding mode, and it can shift the computational complexity from encoder to decoder. That makes it very suitable for wireless video terminals with limited computing capabilities, memory and power. This technology is rapidly developing with emerging video applications such as wireless video surveillance, wireless digital camera and mobile video telephony. This paper summarizes the distributed video coding technology from the theory to the application from the perspective of basic principle, coding framework, key technology and development trend. On the basis of these, this paper proposes several aspects of distributed videocoding that is worthy of further study.

Distributed videocoding (DVC) is an emerging video coding technology that utilises information theory for distributed sources to build a very simple encoder. In the DVC codec, the reconstruction function for the Wyner-Ziv (WZ) frame is one of the most important modules for improving the quality of the decoded image. An efficient reconstruction algorithm is proposed that uses neighbour pixel information. Simulation results show that the proposed algorithm improves the quality of the decoded image without an increase in the bit rate.

Recent advances in video coding technology have resulted in rapid growth of application in mobile communication. With this explosive growth, reliable transmission and error resilient technique become increasingly necessary to offer high quality multimedia service. This paper discusses the error resilient performances of the MPEG-4 simple profile under the H.324/M and the H.264 baseline under the IP packet networks. MPEG-4 simple profile has error resilient tools such as resynchronization marker insertion, data partitioning, and reversible VLC. H.264 baseline has the flexible macroblock ordering scheme, and others. The objective and subjective quality of decoded video is measured under various random bit and burst error conditions.
With the development of video coding technology, the high efficiency videocoding (HEVC) provides better coding efficiency compared to its predecessors H.264/AVC. HEVC improves rate distortion (RD) performance signifi...
