Error concealment in a video signal

摘要

A video sequence has a plurality of frames encoded as at least two independently-coded signals 10a, 10b, each of which represents a sub-set of frames of the video sequence. An error in a frame P4 of the video sequences is concealed by predicting corresponding data using at least one frame P3, P5 which is encoded in a signal 10b other than that in which the error is identified.
