Abstract
A method for encoding a video stream with at least one frame having a plurality of blocks of pixels including a current block. The method includes identifying, peripheral to the current block, a first set of pixels and a second set of pixels in the at least one frame, wherein the first set of pixels has been coded; determining whether the second set of pixels has been coded; and determining, for the current block, a prediction block using the first set of pixels and the second set of pixels based on the determination of whether the second set of pixels has been coded.
