PCR restamper

摘要

An MPEG multiplexed data transmission system accepts data from a plurality of sources and supplies them, on a packet basis, to a common data stream. The non uniform jitter experienced by the packets is determined by subtracting the average delay for packets in a program from the current packet delay. PCR packets have their time base extracted, corrected for the calculated non uniform time delay and replaced as the PCR packet is supplied to the common data stream. Only PCR packets are modified
