Abstract
In some embodiments, a method includes generating a first image data frame, a first error image data frame and a second error image data frame based at least in part on a bitstream. The method further includes upscaling or de-quantizing the first image data frame to provide a first predicted image data frame, generating a second image data frame based at least in part on the first predicted image data frame and the first error image data frame, upscaling or de-quantizing the second image data frame to provide a second predicted image data frame, and generating a third image data frame based at least in part on the second predicted image data frame and the second error image data frame. In some embodiments, an apparatus includes a storage medium having stored instructions that when executed by a machine result in the method.
