An outlet (70, 75, 76, 78, 79) for a Local Area Network (LAN), containing an integrated adapter (21, 25) that converts digital data to and from analog video signal. Such an outlet allows using analog video units in a digital data network (80), eliminating the need for a digital video units or external adapter. The outlet may include a hub (31, 41) that allows connecting both an analog video signal via an adapter, as well as retaining the data network connection, which may be accessed by a network jack (73). The invention may also be applied to a telephone line-based data networking system. In such an environment, the data networking circuitry as well as the analog video adapters are integrated into a telephone outlet, providing for regular telephone service, analog video connectivity, and data networking as well. In such a configuration, the outlet would have a standard telephone jack (71), an analog video jack (72) and at least one data networking jack (73). Outlets according to the invention can be used to retrofit existing LAN and in-building telephone wiring, as well as original equipment in new installation.
What is claimed is: 1. A video network in a building for carrying a video signal from a video source to a video receiver, said network comprising:at least two outlets;pre-existing wiring in at least one wall of the building, said wiring comprising at least two conductors and being connected to said
What is claimed is: 1. A video network in a building for carrying a video signal from a video source to a video receiver, said network comprising:at least two outlets;pre-existing wiring in at least one wall of the building, said wiring comprising at least two conductors and being connected to said at least two outlets, said at least two conductors comprising one of: a twisted-wire pair; a CATV coaxial cable; a telephone wire pair; and AC power wiring, and being connected to carry an analog service signal in an analog service signal frequency band, the analog service signal being one of: DC power; a CATV signal; an analog telephone signal; and an AC power signal, and being connected to concurrently carry a frequency multiplexed bi-directional serial packet-based digital data signal in a digital data signal frequency band distinct from the analog service signal frequency band, the digital data signal comprising at least one packetized and digitized video data signal; anda first device connected to said wiring and connectable to an analog video source, said first device being operative to digitize and packetize the analog video signal from the analog video source and to couple the digitized and packetized analog video signal to the wiring; anda second device connected to said wiring and connectable to an analog video receiver, said second device being operative to convert the digitized and packetized data received from the wiring back into the analog video signal for coupling to the analog video receiver.
