摘要： A method and apparatus for independent video and graphics scaling in a video graphics system is accomplished by receiving a video data stream, wherein the video data stream includes video data in a first format. A graphics data stream is also received, and the graphics data stream includes graphics data in a second format. The video data of the video data stream is scaled based on a ratio between the first format and a selected video format to produce a scaled video stream. Similarly, the graphics data of the graphics data stream is scaled based on a ratio between the second format and a selected graphics format in order to produce a scaled graphics stream. The scaled video stream and the scaled graphics stream are then merged to produce a video graphics output stream.

摘要： An improved deinterlacing technique reconstructs regions of an image that change monotonically in the vertical direction (i.e., vertical deinterlacing). The present invention adapts to the image content without using spatio-temporal interpolation techniques. Rather, deinterlacing in accordance with the teachings of the present invention uses, for example, four localized input pixel values to produce an output pixel value that minimizes spatial artifacts (i.e., accurately reconstructs regions that change monotonically in the vertical direction). In another embodiment, an overlay scaler shares overlay scaling circuitry and deinterlacing circuitry to provide a cost effective implementation of a unique deinterlacing circuit. In another embodiment, a plurality of offsets are used in addition to three or more pixels.

摘要： A method for deinterlacing interlaced video using a graphics processor includes receiving at least one instruction for a 2D/3D engine to facilitate creation of an adaptively deinterlaced frame image from at least a first interlaced field. The method also includes performing, by the 2D/3D engine, at least a portion of adaptive deinterlacing based on at least the first interlaced field, in response to the at least one instruction to produce at least a portion of the adaptively deinterlaced frame image. Once the information is deinterlaced, the method includes retrieving, by a graphics processor display engine, the stored adaptively deinterlaced frame image generated by the 2D/3D engine, for display on one or more display devices. The method also includes issuing 2D/3D instructions to the 2D/3D engine to carry out deinterlacing of lines of video data from interlaced fields. This may be done, for example, by another processing device, such as a host CPU, or any other suitable processing device.

摘要： Circuitry for better integrating multiview-based 3D display technology with the human visual system includes logic that identifies an object of interest from a plurality of objects in a multiview-based 3D scene displayed on one or more displays and provides focus adjustment control data for eyewear to view the 3D scene based on perceived distance data corresponding to the identified at least one object of interest and the identified at least one object of interest. In one example, the circuitry includes logic that determines the perceived distance data corresponding to the at least one object of interest based on inter-object distance data indicating a horizontal offset between the at least one object of interest in a first scene view and the same at least one object of interest in a second scene view and display distance data indicating the distance between one or more display screens and a viewing position. Related methods are also set forth.

摘要： A method of mapping motion pictures experts group (MPEG) video information for improved efficiency is presented, wherein image information is stored in blocks of memory referred to as tiles. Tiles are mapped in memory so that adjacent tiles only correspond to different banks of memory. A method and system is provided for organizing and routing multiple memory requests from a plurality of clients to multiple memories. Requests from a plurality of clients, including a plurality of clients of the same type, such as multiple MPEG decoders, are directed to different memory controllers by a router. The memory controllers order the client requests by requests among similar client types. The memory controllers also order the client requests by different client types. The ordered requests are then delivered to memory. Returned data is sent back to the clients.
