Multiple description motion compensation video coding with leaky prediction

Multiple description (MD) coding has been shown to possess excellent error resilience capability for streaming video over lossy packet networks. Multiple description motion compensation coding (MDMC) also is a MD coding with predictive coding scheme. In such a scheme there are "drift" error propagation, caused by the mismatch between the reference frames used in encoding and decoding. To control error propagation usually lose some predictive efficiency. In this paper, we propose an algorithm based on MD coding with modified multiple description scalar quantization (MDSQ) and leaky predictions to reduce drift without too much lowering of efficiency. Simulation results indicate that the proposed coder with leaky prediction outperforms the normal MDSQ coder even with same prediction scheme. The proposed coder is applicable for error prone wireless networks.
