摘要： An integrated graphics processor provides a type of universal programmable synchronization signal generation that provides a plurality of different formats of display synchronization signals. In one embodiment, the integrated graphics processor includes a graphic and video blender that mixes image layers together prior to output for display. The graphics and video blender receives graphics and video data obtained from a frame buffer that may contain multiple formats of data, such as data in different color spaces, such as in a YUV color space (i.e., as per ITU-R BT709 or ITU-R BT 601), and in RGB color space. The integrated graphics processor also includes an integrated (internal or on-chip) programmable embedded synchronization signal generator operatively coupled to the graphic and video blender, to provide a plurality of different formats of display synchronization signals for blended information based on a type of display device. Accordingly, the integrated graphics processor can be programmed to provide suitable luma and chroma display information for different types of display devices, such as standard television displays, HDTV displays, and other displays that may require, for example, embedded synchronization signals, an embedded multilevel synchronization signal, or a separate synchronization signal.

摘要： A method and apparatus for processing DVD video data and sub-picture data is accomplished by storing a line of DVD video data and at least a partially decoded portion of DVD sub-picture data. The partially decoded DVD sub-picture data is still in an encoded format, which may be two bits per pixel, but line information has been decoded from the DVD subpicture data stream. Once stored, the DVD video data is retrieved from the memory and scaled to produce scaled video data. Similarly, the partially decoded sub-picture data is retrieved from memory, further decoded, and scaled to produce scaled sub-picture data. The scaled video data is blended with the scaled sub-picture data to produce a video output.

摘要： System and method for providing control data for dynamically adjusting lighting and adjusting video pixel data for a display to substantially maintain image display quality while reducing power consumption. In accordance with one or more embodiments, image statistics, e.g., histogram data representing luma values corresponding to pixels for a video frame, are analyzed to determine whether the pixels represent one or more of a plurality of images which includes an image containing primarily natural imagery, an image containing primarily graphics imagery, and an image containing a combination of at least respective portions of natural and graphics imagery. Based on such analysis, control data are provided to enable light source brightness reduction by one of a plurality of percentages and pixel brightness increases, e.g., in accordance with one of a plurality of multiple-segment piecewise linear curves defined in accordance with respective segment slopes, thresholds, and threshold offsets in accordance with whether the incoming pixel data primarily represents a natural image, primarily represents a graphics image, or represents a combination of natural and graphics images.

摘要： An image processing circuit, such as a graphics accelerator chip or any other suitable circuit, includes display output control logic that is operative to receive a current frame of information from a frame buffer and is operative to process a current frame, such as by providing gamma correction, image scaling, graphics or video overlaying, or other suitable processing, to produce a processed current display frame and stores the processed current display frame back in the frame buffer. Fixed function or dedicated, display type specific temporal processing logic receives the processed current display frame stored in the frame buffer and also obtains at least one previous processed current display frame from the frame buffer and temporally processes pixels from each of the processed current display frame and the previous processed current display frame to produce a temporally compensated display frame for a specific type of display.

摘要： Spatial or temporal interpolation may be performed upon source video content to create interpolated video content. A video signal including the interpolated video content and non-interpolated video content (e.g. the source video content) may be generated. At least one indicator for distinguishing the non-interpolated video content from the interpolated video content may also be generated. The video signal and indicator(s) may be passed from a video source device to a video sink device. The received indicator(s) may be used to distinguish the non-interpolated video content from the interpolated video content in the received video signal. The non-interpolated video content may be used to “redo” the interpolation or may be recorded to a storage medium.
