Video information processing system with selective chroma deblock filtering

摘要

A video information processing system including a processing circuit and a deblocking filter. The processing circuit provides video information including a chroma component and a luma component. The deblocking filter has an input receiving the video information and an output providing filtered video information, and is configured to selectively disable chroma deblock filtering while luma deblock filtering is enabled. The processing circuit may include a video encoder or a video decoder. The processing circuit may further include control logic providing a control signal to disable chroma deblock filtering within either or both the encoder and decoder. The video encoder may incorporate control information in the output bitstream to control deblock filtering in the downstream decoder to maintain consistency between the encoder and the decoder.

1. A deblocking filter for deblock filtering video information which includes luma information and chroma information, said deblocking filter comprising:
a luma deblocking filter which deblock filters said luma information; a chroma deblocking filter which deblock filters said chroma information; and control logic which is configured to disable said chroma deblocking filter for at least one macroblock of said video information while said luma deblocking filter is enabled for said at least one macroblock of said video information.
