Abstract
A current block and a reference frame used to compress the current block are selected from a bitstream. The reference frame has an alternate reference block created by obtaining a preliminary alternate reference block for the current block, obtaining a predictor block that is generated based on a frame other than the current frame, and creating the alternate reference block when the difference between the two predictors is less than a threshold. The alternate reference block is created by using certain blocks from the sequence of frames that are more different from the preliminary alternate reference block than other non-selected blocks. The current block is decoded using the alternate reference block. In this way, a predictor block that is different from a golden frame predictor is made available when an existing alternate reference block is too similar to the golden frame predictor to be useful.
