Outlet with analog signal adapter, a method for use thereof and a network using said outlet

A network for coupling first and second digitized video data carried as part of respective first and second bi-directional serial packet-based digital data streams external to a building to respective ones of first and second analog video units in the building, said network comprising:

• first wiring comprising two first conductors at least in part in walls of the building and at least in part external to the building, said first wiring being connected to carry the first and second bi-directional serial digital data streams in time-multiplexed form;
• second wiring comprising two conductors at least in part in walls of the building, said second wiring being connected to carry the second bi-directional serial packet-based digital data stream;
• a first outlet mounted in a wall opening or outlet opening and connected to said first wiring;
• a second outlet mounted in a wall opening or outlet opening and connected to said second wiring;
• a first device couplable to a first analog video unit and connected to said first outlet for connecting to said first wiring, said first device being connected to said second wiring and being operative to couple the first digitized video data to the first analog video unit and to pass only the second bi-directional serial digital data streams between said first and second wirings;
• and
• a second device couplable to a second analog video unit and connected to said second outlet for connecting to said second wiring, said second device being operative to couple the second digitized video data to the second analog video unit.

A device for coupling a digitized version of analog signals to one or more analog devices, for use with wiring installed in walls of a building and connected for carrying a bi-directional digital data signal and a power signal over the same wires, the digital data signal containing the digitized version of the analog signals, said device comprising:

• a wiring connector connectable to the wiring;
• a transceiver coupled to said wiring connector for transmitting and receiving the digital data signal carried over the wiring and containing both a digitized version of a first analog signal and a digitized version of a second analog signal;
• a first analog connector for receiving the first analog signal in analog form from an analog device;
• a second analog connector for transmitting the second analog signal in analog form to an analog device;
• an analog to digital converter coupled between said first analog connector and said transceiver and operative for converting the first analog signal from analog form to the digitized version;
• a digital to analog converter coupled between said second analog connector and said transceiver and operative for converting the second signal from the digital version to analog form;
• and
• a single enclosure housing said wiring connector, said transceiver, said converters and said first and second analog connectors,
• wherein said transceiver and said converters are coupled to the wiring in order to be powered by the power signal.
