Abstract
A video processing system has a source device and a sink device. The source device compresses raw video data and transmits the resulting compressed video data and at least some of the raw video data to the sink device. The sink device decompresses the transmitted compressed video data and generates a reconstructed output video frame, where each region of the output frame is based on a selection of either the corresponding raw video data or the corresponding decompressed video data. By using raw video data for some of the regions of the output frame, noticeable artifacts resulting from using a lossy video compression/decompression algorithm can be omitted. In one embodiment, the sink device compares regions of raw and decompressed video data to select data for the output frame and requests the source device to transmit specific regions of new raw video data based on those comparisons.
