Abstract
A video codec comprising a processor configured to generate a prediction block for a current block, compute a difference between the current block and the prediction block to generate a residual block, scan a plurality of prediction residuals located in the residual block following a scanning order, and if the plurality of residual values comprise at least one non-zero prediction residual, entropy encode the at least one non-zero prediction residual. A method comprising generating a prediction block for a current block, computing a difference between the current block and the prediction block to generate a residual block, scanning a plurality of prediction residuals located in the residual block, and if the plurality of residual values comprise at least one non-zero prediction residual, entropy encoding the at least one non-zero prediction residual.
