Efficient Video Streaming in Wireless P2P Network Using HIS-MDC Technique

In this paper, we propose a technique which enhances continuous flow of streaming despite packet loss, error resilience and quality of service using multiple descriptions coding (MDC). The main aim of MDC is to encode a video into multiple frames called descriptions, supporting multiple stages of decoding and when compared to layered coding techniques, each description can be decoded separately to estimate the model. In this proposed work we improve the error resilience and user heterogeneity using new multiple description coding method called Hybrid Interpolation Scalable MDC (HIS-MDC) technique and using both spatial and temporal interpolation schemes corrupted portions of a frame are concealed. Experimental results show that, proposed approach attains reasonable quality of video performance compared with previous multiple description methods.
