Abstract:
1. A data stream control system connectable to a storage device, the data stream control system selectively storing a series of selected data packets from an incoming data transport stream, the data stream control system comprising: a transport stream input interface that receives the incoming data transport stream comprising selected data packets having interpacket time intervals between the selected data packets; a command interface that receives at least one packet filter parameter identifying the series of selected data packets; a programmable data packet filter coupled to the command interface and transport stream input interface, the programmable data packet filter transmitting the series of selected data packets in response to the packet filter parameter and the incoming data transport stream; a storage interface coupled to the programmable data packet filter and connectable to the storage device, the storage interface transmitting the selected data packets to the storage device; and a counter that provides counter values for the selected data packets, each counter value representing a time of reception of a respective selected data packet, whereby the counter value is stored in association with the respective selected data packet to preserve information regarding the interpacket time intervals of the series of selected data packets from the incoming data transport stream.
