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.
