A device for coupling an analog video unit to AC power wiring, the AC power wiring being connected for concurrently carrying an AC power signal in an AC power frequency band and serial bi-directional packet-based digital data including digitized video data in a digital data frequency band that is distinct from and higher than the AC power frequency band, said device comprising:

  • a power line connector operative for connecting said device to the AC power wiring outside said device;

    a high pass filter coupled to said power line connector for substantially passing only signals in the digital data frequency band and for substantially rejecting signals in the AC power frequency band;

    a power line modem coupled to said high pass filter for conducting the serial bi-directional packet-based digital data over the AC power wiring;

    an analog video connector connectable for coupling an analog video signal to the analog video unit outside said device;

    a converter between the analog video signal and a digitized video data signal coupled to said analog video connector, said converter comprising at least one of an analog to digital converter and a digital to analog converter;

    a multi-port packet sharing means consisting of one of;

    a switch;

    a router; and

    a gateway, coupled to pass only the digitized video data between said converter and said power line modem; and
