Error resilience analysis of multihypothesis motion compensated prediction for video coding
The relationship between the error propagation effect and the hypothesis coefficients of the multihypothesis motion compensated prediction (MHMCP) is analyzed in this work. MHMCP enhances the error resilience of compressed video but demands a higher bit rate for the motion information. We study the rate-distortion performance of MHMCP in an error prone environment and then perform extensive experiments to conform the analytical results. Several design guidelines for MHMCP coders are drawn based on the analytical and experimental results.
