ABSTRACT:
An apparatus and method for asynchronous compression of video information in a computer system. The apparatus includes data structures and functions for specifying synchronous or asynchronous compression of at least one uncompressed video frame, for specifying latency in the compression of the at least one uncompressed video frame, for initiating asynchronous compression of the at least one uncompressed video frame by a video compressor, for asynchronously retrieving from the video compressor at least one compressed video frame, for terminating asynchronous compression of the at least one uncompressed video frames by the video compressor, and for immediately retrieving from the video compressor the at least one compressed video frame when the at least one compressed video frame remains unretrieved after asynchronous compression is terminated.
