Abstract:
1. A method for distributing an MPEG clock over an internal network by recovering an MPEG clock from a stream of data received from an external network, comprising the steps of: recovering an MPEG related clock from a stream of MPEG data received from the external network at a network interface unit; selecting a program from the stream using an MPEG transport chip located within the network interface unit; direct locking a local clock to the recovered MPEG related clock to provide an internal clock for the internal network which is locked to said recovered MPEG related clock; transmitting the MPEG data from the network interface unit over the internal network according to the internal clock; synthesizing the MPEG clock at set-top electronics coupled to the internal network from the MPEG data transmitted over the internal network according to the internal clock.
