Abstract
A method of adaptively disabling deblock filtering of video information including determining a content characteristic of the video information, and adaptively disabling deblock filtering of the video information based on the content characteristic. The content characteristic may be a content complexity, such as an average of minimum sums of absolute differences of pixel values determined during motion estimation, or the mean square error of the video information, or the number of bits used for coding the video content. The content characteristic may be other than complexity, such as motion vector information. A video information processing system including a video processing circuit which processes video information and which determines a content characteristic of the video information, and a deblocking filter circuit which adaptively disables deblock filtering of the video information based on the content characteristic.
