ABSTRACT:
A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks and perform MPEG clock recovery from an MPEG video data stream. To prevent jitter when the MPEG data stream is transmitted over the internal network to set-top electronics, the recovered MPEG clock is locked by the network interface unit to the internal network clock and then transmitted over the internal network. The set-top electronics then recovers the MPEG clock from the locked MPEG clock transmitted over the internal network. The video data may then be generated using the recovered MPEG clock and displayed on a television, for example.
