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.

Abstract: Virtual Reality (VR) processing devices and methods are provided for transmitting user feedback information comprising at least one of user position information and user orientation information, receiving encoded audio-video (A/V) data, which is generated based on the transmitted user feedback information, separating the A/V data into video data and audio data corresponding to a portion of a next frame of a sequence of frames of the video data to be displayed, decoding the portion of a next frame of the video data and the corresponding audio data, providing the audio data for aural presentation and controlling the portion of the next frame of the video data to be displayed in synchronization with the corresponding audio data.

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 index 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: A display system includes a rendering device and a display device having a plurality of individually-controllable illumination regions. The rendering device is to render a frame for display at the display device during a frame period and to determine a brightness representation for each region of a plurality of regions of the frame, each region of the frame corresponding to an illumination region of the display device. The rendering device further is to set, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period and a subsequent frame period based on the brightness representation for the corresponding region of the frame, wherein the illumination configuration controls at least one of an illumination level, a duration, and a position of an illumination strobe to be implemented for the corresponding illumination region.
