DYNAMIC INTRA-CODED MACROBLOCK REFRESH INTERVAL FOR VIDEO ERROR CONCEALMENT

The present invention provides, in one embodiment, a system and method for concealing video errors. The system includes a coding engine for processing each frame of a video signal to generate macroblocks, selecting a refresh interval based upon network communication parameters, and encoding one or more of the macroblocks as refresh intra-coded macroblocks based upon the selected refresh interval. The refresh intra-coded macroblocks are placed into discrete data packets for transmission across a network to one or more remote devices. Upon receiving other refresh intra-coded macroblocks from a remote device via the network, the coding engine decodes the received intra-coded macroblocks, and places the decoded macroblocks in a newly decoded video frame to be used as reference frame macroblocks for reducing video errors associated with prediction drift.
