CROSS-CHANNEL RESIDUAL PREDICTION

摘要

Systems, apparatus and methods are described including determining a prediction residual for a channel of video data; and determining, using the first channel's prediction residual, a prediction residual for a second channel of the video data. Further, a prediction residual for a third channel of the video data may be determined using the second channel's prediction residual.

1. A video decoder comprising:
circuitry to receive at least a portion of a bitstream; circuitry to determine a luma predicted residual value based on the received bitstream; and circuitry to:
in response to a flag related to the bitstream that is to indicate use of cross channel residual prediction:for one or more pixel positions:
determine a product of a linear factor and the luma predicted residual value anddetermine a chroma value based at least in part on the product of the linear factor and the luma predicted residual value.
