When losses occur in a transmission of compressed video, the decoder can attempt to conceal the loss by using spatial or temporal methods to estimate the missing macroblocks. We consider a multi-frame error concealment approach which exploits the uneven quality in the two reference frames to provide good concealment candidates. A binary decision tree is used to decide among various error concealment choices. The uneven quality of the reference frames provides an advantage for error concealment.
In the decoder side, an error concealment method was later used to take advantage of such prediction structure REF .
