摘要
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 by compressing a plurality of video data objects into a plurality of compressed video data objects, storing the plurality of compressed video data objects in a compressed frame buffer. The data object compression/decompression module retrieves a selected portion of video frame data from the compressed video frame buffer by identifying selected ones of plurality of compressed video data objects that correspond to the selected portion of video frame data, retrieving the selected ones of the plurality of compressed video data objects and generating the uncompressed video frame data by decompressing the selected ones of the plurality of compressed video data objects.
