<p>A data stream control system and method for selectively storing a series selected data packets with interpacket time intervals from an incoming transport stream. The data stream control system (2) includes a programmable data packet filter (70) that transmits the series of selected data packets in response to the packet filter parameter. A counter (90) provides counter values for the selected data packets representing a time of reception for the respective selected data packet. The counter values (100) are stored in association with the respective selected data packets (30) to preserve information regarding the interpacket time intervals. The data stream control system can further include a timing restorer to transmit a stored series of selected data packets with interpacket time intervals which substantially match the corresponding interpacket time intervals of the series of selected data packets.</p> |
