Abstract: To apportion desired video processing between a video source device and a video sink device, at one of the devices, and based upon an indication of video processing algorithms of which the other device is capable and an indication of video processing algorithms of which the one device is capable, a set of video processing algorithms for achieving desired video processing is identified. The identified set of video processing algorithms is classified into a first subset of algorithms for performance by the other device and a second subset of algorithms for performance by the one device. At least one command for causing the other device to effect the first subset of video processing algorithms is sent. The one device may be configured to effect the second subset of algorithms.

Abstract: An image rendering unit (IRU) of a device determines the dynamic frame rate capabilities (DFRCs) of a display and an image frame rate of content to be displayed. Preferably, the DFRCs are stored in a storage device deployed within the display itself. Based on the DFRCs and the image frame rate for the content, the IRU determines an updated frame rate and thereafter provides the content to the display at the updated frame rate. Where control of power consumption is desired, selection of a reduced frame rate can effect a power savings. In this manner, the present invention provides flexible control over display frame rates and/or power consumption of the device.

Abstract: There are many instances where a standard dynamic range (“SDR”) overlay is displayed over high dynamic range (“HDR”) content on HDR displays. Because the overlay is SDR, the maximum brightness of the overlay is much lower than the maximum brightness of the HDR content, which can lead to the SDR elements being obscured if those elements have at least some transparency. The present disclosure provides techniques including modifying the luminance of either or both of the HDR and SDR content when an SDR layer with some transparency is displayed over HDR content. A variety of techniques are provided. In one example, a fixed adjustment is applied to pixels of one or both of the SDR layer and the HDR layer. The fixed adjustment comprises decreasing the luminance of the HDR layer and/or increasing the luminance of the SDR layer. In another example, a variable adjustment is applied.

Abstract: In some examples, an apparatus obtains source layer pixels, such as those of a content image and first destination layer pixels, such as those of a destination image. The first destination layer pixels have associated alpha values. The apparatus obtains information that indicates a first blending color format for the alpha values. The first blending color format is different from a first destination layer color format for the first destination layer pixels and an output color format for a display. The apparatus converts the source and/or first destination layer pixels to the first blending color format. The apparatus generates first alpha blended pixels based on alpha blending the source layer pixels with the first destination layer pixels using the associated alpha values. The apparatus provides, for display on the display, the first alpha blended pixels.

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 supports variable refresh rates that include a plurality of refresh rates. A source such as a graphics processing unit (GPU) provides frames to the display system at a selected one of the refresh rates. The refresh rates are factored into a corresponding plurality of prime factors. A plurality of numbers of lines per frame in frames provided at the plurality of refresh rates is determined based on one or more ratios of the plurality of refresh rates, the plurality of prime factors, and a line rate for providing frames to the display system at the plurality of refresh rates. The source then selectively provides frames to the display system at one refresh rate of the plurality of refresh rates using the same line rate regardless of which refresh rate is chosen. Furthermore, the number of lines per frame is an integer for frames provided at the refresh rates.

Abstract: A method and apparatus for providing an image on a vertical scan panel determines whether a mode of operation for a vertical scan panel is either a scan conversion pass-through mode or a horizontal scan conversion mode. If the determined mode is the horizontal scan conversion mode, the method and apparatus converts display data in the vertical scan panel from a horizontal scan format to a vertical scan format and displays the converted display data on the vertical scan panel. However, if the determined mode is the scan conversion pass-through mode, the method and apparatus includes displaying display data on the vertical scan panel in a vertical scan format without applying a scan conversion operation on the display data.
