Optimization of decoder instance memory consumed by the jitter control module

Abstract

A decoder for decompressing real-time media data streams and a method for operating such a decoder is disclosed. The decoder may comprise a relatively larger first memory for storing compressed data and parameters, and a processor for executing a decompression algorithm, the processor having a relatively smaller second memory. The decompression algorithm may be executed on a periodic basis, and the parameters used to select the data to be decompressed may be moved from the second memory to the first memory each time the decompression algorithm executes. An embodiment of the present invention may use slower, less expensive memory to enable it to support a greater number of real-time media streams than prior art solutions. Another embodiment of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing.
