    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.

    摘要: A video adjustment system for processing video information is disclosed which includes a motion analyzer and an adjustment module. The motion analyzer determines a motion level metric of the video information based on at least one motion parameter. The adjustment adjusts an initial dynamic light scaling factor to provide an adjusted dynamic light scaling factor based on the motion level. The dynamic light scaling factor may be used for luminance compensation and backlight display scaling. The motion level may be based on any type of motion information, such as motion vector information or information indicating a scene change. A distortion module may perform a distortion evaluation of the video information for calculating the initial scaling factor. Alternatively, the distortion module may include a memory which stores predetermined scaling factors based on statistical distortion level characterization.

The method may include bypassing evaluating conditions and deblock filtering associated with the maximum boundary strength. The method may include bypassing evaluating second conditions and bypassing corresponding deblock filtering if the intermediate edge is a horizontal edge. The method may include bypassing less efficient memory reads associated with component values used for evaluating the second conditions.

    摘要: A rate control system for a video encoder including rate control logic which determines a first QP corresponding to a selected encoding layer of multiple encoding layers, and scaling logic configured to scale the first QP to a second QP corresponding to any other encoding layer based on at least one encoding layer parameter. A template of stored QP values may be used to reduce computational complexity, such as a QP value for each frame interval or a QP value for each of multiple rate control interval complexity values. The QP values in the template may be predetermined or programmed and updated during periodic training sessions. Several encoding layer parameters are contemplated, such as any combination of bit rate, frame rate and frame resolution. The scaling logic may be configured to scale from any one encoding layer to another and vice-versa for bi-directional scaling.
