Set-top electronics and network interface unit arrangement
First Claim
1. A set-top electronics and network interface unit arrangement, comprising:
- a network interface unit having a network interface module adapted for connection to an external network, and an internal network interface for interfacing to an internal digital network, the network interface unit providing a signal from an external network to the internal digital network, wherein the internal network interface of the network interface unit includes an MPEG to internal network synthesizer that converts clocking of the signal from an MPEG clocking to an internal network clocking;
a set-top electronics unit having an internal network interface device adapted for connection to the internal digital network for interfacing to the internal digital network to receive a signal from an internal network, a signal converter coupled to the network interface device and converting a signal received by the internal network interface device for use by an end terminal;
an MPEG transport included with network interface unit, coupled to the network interface module, for selecting a single program from a plurality of programs in a signal; and
whereby, the network interface unit and the set-top electronics unit are at least physically and fuctionally separated by the internal network.

Abstract
A set-top electronics and network interface unit arrangement is connected to an internal digital network interconnecting devices in the home. The digital network operates on a single, nomodulated, baseband channel. 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 make the entertainment services available to all terminals connected to the internal network. Set-top electronics that are separate from the network interface units connect to the internal network and convert the information in the digital data stream for display, by a television, for example.

7. A network interface unit for use in coupling an external network to an internal digital network, wherein at least one set-top electronics unit is connected to the internal digital network, the network interface unit comprising:
-
at least one network interface module adapted for connection to the external network;
at least one transport device, coupled to the network interfere module, for selecting a single program from a plurality of programs in a first signal received from the external network via the network interface module;
an internal network interface, coupled to the transport device, for interfacing to the internal digital network, wherein the network interface unit provides a second signal that includes the single program to the internal digital network; and
wherein said internal digital network operates on a baseband channel. - View Dependent Claims (8, 9, 10, 11, 12)
