Efficient adaptive mode selection technique for H.264/AVC-coded video delivery in burst-packet-loss networks

摘要

A method of an efficient adaptive mode selection for H.264/AVC-coded video delivery in burst-packet-loss networks to generate the image data of the missing macroblocks in the decoded current frame by using the information related to the spatial redundancy in the same frame and the temporal redundancy in the inter frames is disclosed. The method first employs the Intra High-Speed Spatial Error Concealment (SEC) method for the initial frame. For the succeeding inter frames, the Temporal Error Concealment (TEC) method is used when the Adjacent External Boundary Matching Error (AEBME) of the surrounding macroblocks is not more than the dynamic threshold (DTα). The Intra High-Speed SEC is used when AEBME is more than (DTα) and the surrounding macroblocks are all coded intra-method, otherwise the task proceeds by employing Normal SEC.
