ABSTRACT:
Overlay buffering scheme for multi-channel data in which one memory buffer content is overlayed over another as memory locations of an input buffer are freed when data is output from the input buffer. By overlaying the buffer content, only one input buffer is used, reducing the needed memory by half.
