摘要： A wireless display system and method decompresses a compressed video stream, such as obtained from suitable video sources such as a cable modem, DVD player or other suitable source, to produce a decompressed video stream locally. The decompressed video stream, such as frames, is stored in a local frame buffer, such as an on-chip frame buffer, system memory, or any other suitable memory. The system and method then recompresses the stored frames and wirelessly transmits the recompressed frames using a short range wireless transmitter, such as a radio frequency-based short range transmitter, an infrared short range wireless transmitter, or any other suitable short range transmitter that may provide, for example, local area networking. Accordingly, full image frames are decompressed and then recompressed, such as via a software data encoder as executed by a central processing unit, or via a hardware data encoder, such as an MPEGII or MPEG4 encoder, or any other suitable encoder, and then modulated by a short range wireless transceiver and sent to a short range wireless unit having a local display.

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： Multiple Video Graphic Adapters (VGAs) are used to render video data to a common port. In one embodiment, each VGA will render an entire frame of video and provide it to the output port through a switch. The next adjacent frame will be calculated by a separate VGA and provided to an output port through the switch. A voltage adjustment is made to a digital-to-analog converter(DAC) of at least one of the VGAs in order to correlate the video-out voltages being provided by the VGAs. This correlation assures that the color being viewed on the screen is uniform regardless of which VGA is providing the signal. A dummy switch receives the video-output from each of the VGAs. When a VGA is not providing information to the output port, the dummy switch can be selected to provide the video-output of the selected VGA a resistance path which matches the resistance at the video port. This allows the video graphics controller to maintain a constant thermal state.
