Abstract:
A video processing device includes a video processing unit that decodes a video input signal into a decoded video signal in accordance with a video compression protocol, based on uncompressed video frame data. A data object compression/decompression module generates compressed video frame data for storage in a compressed video frame buffer by compressing a plurality of video data objects into a plurality of compressed video data objects, wherein a first subset of the plurality of video data objects are compressed via lossless compression and a second subset of the plurality of video data objects are compressed via lossy compression.
