A novel video coding scheme for lossy networks with scalable bit-stream

A novel video coding scheme is presented with superior performance against packet losses and hence is suitable for wireless communication compared to standard approaches like scalable video coding. The scheme also offers a better multi- rate video solution by offering multiple options for receiving videos at each sub-rate. The approach is suitable for use on multiple channels as well as on a single channel. The proposed hybrid scheme is innovative in the manner it combines the two standard styles of video coding, namely Scalable video coding and Multiple Description Coding, to provide a scalable bit- stream. The goal is to provide a better overall comprise between quality and resilience over different loss rates than is offered by either of the two separately as the congestion and hence the loss rate may vary with time. The scheme may offer a good potential to cater needs of emerging multimedia applications based on wireless communication and/or ubiquitous computing. Results of the proposed and existing schemes on different packet loss rates are reported in order to evaluate and compare their performances.
