Error Concealment for Dual Frame Video Coding with Uneven Quality

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 mac-roblocks. 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.
