<P>PROBLEM TO BE SOLVED: To provide a method for reconstruction of video information lost as a result of transmission errors. <P>SOLUTION: A system and method for reconstruction of video information lost as a result of transmission errors have four aspects, comprising: (1) changing a bit and/or packet rate; (2) inserting redundant information into a video bit stream; (3) providing periodic automatic refresh of certain regions of video; and (4) interleaving coded macro blocks into some diversity groups for transmission to spatially spread effect of lost packets. Then, by using these three aspects, image reconstruction may provide an enhanced result in presence of transmission losses. <P>COPYRIGHT: (C)2013,JPO&INPIT |
