A technique for decoding video signals includes receiving, by electronic decoding circuitry, a set of video data representing a two-dimensional array of pixels of a video signal. The set of video data includes (i) multiple residual layers, each residual layer providing an incomplete, lossily-compressed representation of the two-dimensional array of pixels (ii) multiple sets of prediction information, one for each of the residual layers, and (iii) a set of masks for directing reconstruction of the two-dimensional array of pixels. The method further includes generating multiple decompressed layers based on the residual layers and on the sets of prediction information for the respective residual layers and combining the decompressed layers, as directed by the set of masks, to generate a complete reconstruction of the two-dimensional array of pixels of the video signal. |
