Abstract: Multiplexing and demultiplexing are commonplace for an efficient bandwidth utilization in telecommunications. SRTS (Synchronous Residual Time Stamp) technique is widely used for timing recovery in processing of digital signal streams. The bit stuffing is also prevalent for various purposes, one being rate adjustment. The invention performs the SRTS technique entirely digitally to monitor the rate of slower speed signal streams in relation to the rate of a higher speed stream. The digital implementation permits the use of context switching for processing a plurality of digital signal streams. As the result, hardware requirement is greatly reduced.
