    Abstract: A video source, a display and a method of processing multilayered video are disclosed. The video source decodes a multilayered video bit stream to transmit synchronized streams of decompressed video images and corresponding overlay images to an interconnected display. The display receives separate streams of video and overlay images. Transmission and reception of corresponding video and overlay images is synchronized in time. A video image received in the display can be selectively processed separately from its corresponding overlay image. The video image as processed at the display is later composited with its corresponding overlay image to form an output image for display.

    Abstract: A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at a frame rate and to set an illumination configuration to be applied by the display device during a frame period for each frame of the sequence of frames based on the frame rate. The illumination configuration controls at least one of an illumination level and a duration for an illumination strobe, and at least one of an illumination level for an illumination fill preceding the illumination strobe in the frame period and an illumination level for an illumination fill following the illumination strobe in the frame period. The display device is to receive a representation of the illumination configuration from the rendering device and apply the illumination configuration during a frame period for each frame of the sequence of frames to display the frame.

    Abstract: A single source image encoder encodes more than one display stream, such as multiple display streams each for a different display or multiple display streams for the same display, using multiple indexed color history (ICH) buffers. As applied to a DSC encoder, the same DSC encoder is used to encode more than one DSC compliant display stream. Multiple encoded display bitstreams are output as multiple display data streams to a plurality of displays. Such a configuration can significantly reduce the area cost of an integrated circuit that employs an image encoder since additional encoders are eliminated.

    Abstract: Briefly, methods and apparatus to provide image content to, and display image content on, variable refresh rate displays with reduced input lag. The methods and apparatus allow for image tearing, or the displaying of image content from more than one video frame, when the render rate of a provided video frame falls outside the display refresh rate range of a variable refresh rate display when the display is refreshing with a previous frame (e.g. the display is in active refresh), thus reducing the input lag of the content of the provided video frame. The methods and apparatus may also prevent image tearing when the render rate of provided video frames is within the display refresh rate range of a display.
