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
