Method and apparatus for improved video decompression by adaptive selection of video input buffer parameters

摘要

A video decompression system utilizes multiple independent input buffers so that input/output operations and processing take place concurrently, nearly continuously and at a rate that is substantially equal to a selected maximum access rate of the storage device. Consequently, the data rate of the video decompression system is optimized with respect to the rate of data accessing. The video decompression system adaptively sets input buffer parameters as a function, for example, of processor capabilities, bitstream characteristics, drive latency and access time, and file I/O overhead.
