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 make the entertainment services available to all terminals connected to the internal network. A plurality of set-top electronics that do not have network interface units connect to the internal network and prepare the information in the digital data stream for display, by a television, for example.

Claims

1. A multimedia network comprising:

an external network port having a plurality of network interface units, wherein each of the network interface units is configured to provide access to an external network, convert a first signal received from the external network to a corresponding second signal, and output the second signal, and wherein at least one network interface unit further includes a transport device for selecting a single program from a plurality of programs in the first signal and the second signal includes the selected single program;

an internal digital network coupled to the each of the plurality of network interface units and configured to carry each of the second signals output by the plurality of network interface units; and

a plurality of set top boxes coupled to the internal digital network, wherein at least one of the set top boxes is configured to receive at least one of the second signals from the internal digital network, and provide a corresponding third signal to at least one end terminal, and wherein one of the set top boxes receives the one second signal and provides information corresponding to the selected single program to the end terminal via the third signal.

2. The network of claim 1, wherein at least one of the plurality of set top boxes further includes a controller coupled to the internal digital network and configured to control two-way digital communication between the set top box and the internal digital network.

3. The network of claim 1, further including a plurality of processing devices coupled to the internal digital network and configured to exchange processing signals over the internal digital network.

4. The network of claim 3, further including a plurality of peripheral devices coupled to the internal digital network and configured to respond to at least a portion of the processing signals exchanged over the internal network.

5. The network of claim 3, further comprising a home automation network coupled between one of the processing devices and at least one appliance, wherein the processing device is configured to control the appliance in response to at least one signal selected from the group of a second signal and a processing signal as received over the internal digital network.

6. The network of claim 1, wherein the internal digital network is an Ethernet network.

7. The network of claim 6, wherein the Ethernet network is 10 baseT Ethernet.

8. The network of claim 6, wherein the Ethernet network is 100 baseT Ethernet.

9. The network of claim 1, wherein the internal network further includes a hub coupled to the external network port and configurable to provide an interconnection between at least one network interface unit and one set top electronics unit.

10. The network of claim 1, further comprising a local peripheral network coupled between one of the set top boxes and at least one peripheral device, wherein the set top box is further configured to provide an interface between the internal digital network and the local peripheral network.
