US 9,001,899 B2 · Video information processing system with selective chroma deblock filtering

Abstract

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.

Dependent claims

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 to bypass the functions performed for chroma deblock filtering including bypassing data loading of chroma information for chroma deblock filtering, wherein said chroma deblocking filter is disabled for an entire slice of said video information while said luma deblocking filter is enabled for said entire slice of said video information.
