Abstract:
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; and a 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; and a 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.
