Abstract
The advance of wireless networks is turning huge research interest from both industry and academia due to wide variety of services. But due to various reasons bit-errors, packet-losses and burst-packet-losses are very common in such type of networks. These losses have a very destructive effect on the quality of video at receiving end. Providing reliable and robust video streaming over wireless networks is the key issue. In this paper, we propose an Adaptive Unequal Error Protection (AUER) and Packet Size Assignment (PSA) scheme for Scalable Video Coding (SVC) based streaming over error-prone channel toward heterogeneous receivers. First the scheme calculates the quality of all candidate paths and then based on quality of path it decides adaptively the size and level of error protection for all packets in order to combat the effect of losses on perceived quality of reconstructed video. The results show that the proposed streaming approach can react to varying channel conditions with less degradation in video quality.
