DSC QP QUANTIZATION PARAMETER QP UPDATE CLASSIFICATION FOR DISPLAY STREAM COMPRESSION DSC

摘要

A quantization parameter (QP) update classification for display stream compression (DSC) is disclosed. In one aspect, a method for determining a quantization parameter (QP) value includes determining whether a current block includes a transition from a flat region to a complex region, or is not a flat block, and determining whether the previous block is a complex region And determining that the block is a flat block. The method also includes selecting a default technique or an alternative technique to calculate a QP adjustment value for the current block based on whether previous and current blocks include transitions from flat areas to complex areas or are flat blocks . / RTI
