Abstract:
The disclosed embodiments relate to a system for providing remote tuning and clock synchronization in a network. The system includes a device that receives a signal that includes a plurality of channels, a device that receives a user request indicative of a desire to view at least one of the plurality of channels, and a filter that filters the received signal and transmits a user signal corresponding to the at least one of the plurality of channels to the user. An alternative embodiment of the system includes a device that receives a signal that includes a plurality of packets, at least a portion of the plurality of packets comprising an embedded time stamp, a device that detects the at least a portion of the plurality of packets containing the embedded time stamp, and a device that computes an adjusted time stamp based on the embedded timestamp and a precision local clock and incorporates the adjusted timestamp into the at least a portion of the plurality of packets containing the embedded timestamp prior to transmitting the at least a portion of the plurality of packets to the network.
