Spatial error concealment based on the intra-prediction modes transmitted in a coded stream

摘要

Spatial concealment of errors in an intra picture comprised of a stream of macroblocks is achieved by predicting the missing data in a macroblock based on an intra prediction mode specified in neighboring block. In practice, when macroblocks within a stream are coded by a block based coding technique, such as coding technique specified in the H.264 ISO/ITU standard, a macroblock can be predicted for coding purpose based on neighboring intra prediction modes specified by the coding technique.
