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 tile engine includes a tile accumulation module that accumulates the uncompressed video frame data into a plurality of tile units, wherein each of the plurality of tile units includes a plurality of video span units. A tile compression / decompression module generates compressed video frame data for storage in a compressed video frame buffer by compressing the plurality of video span units into a plurality of compressed video span units and further that retrieves the compressed video frame data from the compressed video frame buffer by retrieving the plurality of compressed video span units and generating the uncompressed video frame data by decompressing the plurality of compressed video span units.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C.119 of Provisional Application No. 61 / 755,280, filed January 22, 2013, entitled "VIDEO PROCESSOR WITH FRAME BUFFER COMPRESSION AND METHODS FOR USE THEREWITH," the entire contents of which are incorporated by reference Combined here. technical field [0003] This application relates to encodings used in devices such as video encoders, decoders and transcoders. Background technique [0004] For modern video processing devices, video coding has become an important issue. Robust encoding algorithms allow video signals to be transmitted with reduced bandwidth and stored in smaller memories. However, the accuracy of these encoding methods faces scrutiny by users who become accustomed to higher resolutions and higher image quality. Standards have been developed for a number of encoding methods, including the H.264 standard, also known as MPEG-4, Part 10, or Advanced Video Cod...
