Abstract

External-services data are processed for use in a user facility in a manner that enables easy user interface and control. According to an example embodiment of the present invention, an arrangement for processing external-services data includes an audio, video, and data signal bussing arrangement adapted to distribute audio, video, and data to designated points in a user facility. A plurality of appliances are communicatively coupled to the bussing arrangement and adapted to receive and process one or more audio, video, and data signals. A user input device is adapted to command a network interface unit (NIU) to process the external-services data for use at a particular one of the plurality of appliances in the user facility. External-services data is delivered over the bussing arrangement and to one or more of the plurality of appliances using the (NIU).
