Reliable video communication with multi-path streaming using MDC

Video streaming demands high data rates and hard delay constraints, and it raises several challenges on today´s packet-based and best-effort Internet. In this paper, we propose an efficient multiple-description coding (MDC) technique based on video frame sub-sampling and cubic-spline interpolation to provide spatial diversity, such that no additional buffering delay or storage is required. The frame dropping rate due to packet loss and drifting error under the multi-path streaming environment is analyzed in this paper.
