Abstract
An apparatus for allowing IEEE-1394-enabled devices to communicate with one another across an existing coaxial cable network in, for example, a house. Many houses have been “wired for cable” and have such a cable network in place. The network is, in its native state, unsuitable for IEEE-1394 communication. The apparatus allows processing signals from an IEEE-1394-enabled device for transmission across a coax. Signals received are converted and then provided to IEEE-1394 devices connected to the apparatus. One use for the apparatus is interconnecting audio/visual devices, for example high definition television receivers, DVD players, audio components and the like located in throughout a house to one another. DTCP encryption and decryption may be provided. The apparatus may be equipped with an optional SMI connector to allow communication over an optical fiber in lieu of the coaxial network. The apparatus is self-powered, deriving necessary power from the IEEE-1394 interface itself.
