IEEE 1394 to coaxial cable adapter
First Claim
1. An apparatus to facilitate interconnections of IEEE-1394-enabled devices via existing coaxial wiring, comprising:
- a) a transmitter/receiver having a first input/output (I/O) port adapted for connection to a coaxial cable to allow bi-directionally communicating thereover and a set of I/O ports for interconnection to an IEEE-1394 linking device;
b) an IEEE-1394 linking device operatively connected to said set of I/O ports and having at least two IEEE-1394 I/O ports adapted for interconnection to and communication with an IEEE-1394-enabled device operatively connected thereto; and
c) an apparatus to facilitate interconnection of IEEE-1394-enabled devices, further comprising means for encrypting and decrypting a signal passing therethrough;
whereby an IEEE-1394-enabled device connected to one of said set of IEEE-1394 I/O ports may communicate with another IEEE-1394-enabled device located remotely therefrom via a coaxial cable connected to said first I/O port.

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.
