Abstract
An apparatus used in video encoding 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, wherein the residual block comprises a plurality of residual values, and if the plurality of residual values include at least one non-zero residual value comprising at least one sign and at least one residual level, perform entropy encoding on the at least one sign; and perform entropy encoding on the at least one residual level, wherein one non-residual value comprises one sign and one residual level.
