The error-resilient for video transmission over the Internet in which regarded as the packet erasure channel is always a tough task and has gained lots of attentions. The main contradictory problem lies between error-resilient and bandwidth usage. Additional redundant data has to be added to achieve robust transmission which leads to huge bandwidth usage.(More)
Recently the development of Distributed Video Coding (DVC) has provided the promising theory support to realize the infrastructure of Wireless Multimedia Sensor Network (WMSN), which composed of autonomous hardware for capturing and transmission of quality audio-visual content. The implementation of DVC in WMSN can better solve the problem of energy(More)
The need for efficient multiview video coding schemes is expected to strongly increase in the near future. The distributed multiview video coding (DMVC) approach seems very promising since it can achieve good compression efficiency while keeping the complexity low. The main contribution of this paper is to investigate how to improve the classic DMVC(More)
In this paper, an efficient error resilience scheme aiming to give priority protection to certain area such as region of interest (ROI) in frame based on Wyner-Ziv(WZ) coding for wavelet based video transmission is proposed. By utilizing additional WZ coding, all the corresponding wavelet coefficients related to ROI will be specially protected during(More)
