Abstract
Disclosed herein is a system and method for reconstruction video information lost as a result of transmission errors. The system and method have four aspects, including: (1) changing the bit and/or packet rate; (2) inserting redundant information into the video bitstream; (3) providing automatic refresh of certain regions of the video on a periodic basis; and (4) interleaving coded macroblocks into diversity groups for transmission to spatially spread the effect of lost packets. The image reconstruction may then take advantage of these three aspects to provide an enhanced result in the presence of transmission losses.
