BLOCK ADAPTIVE COLOR-SPACE CONVERSION CODING

摘要

A device for decoding video data includes a memory configured to store video data and one or more processors configured to: receive a first block of the video data; determine a quantization parameter for the first block; in response to determining that the first block is coded using a color-space transform mode for residual data of the first block, modify the quantization parameter for the first block; perform a dequantization process for the first block based on the modified quantization parameter for the first block; receive a second block of the video data; receive a difference value indicating a difference between a quantization parameter for the second block and the quantization parameter for the first block; determine the quantization parameter for the second block based on the received difference value and the quantization parameter for the first block; and decode the second block based on the determined quantization parameter.
