  • Publication number: 20040090970
    Abstract: An apparatus that supports a communication link (such as DSL) in the local loop has hardware to distribute a copy of one or more data flows to any of a number of devices (e.g. “set-top boxes”) that are each connected to the apparatus by the link. In some embodiments, the apparatus receives only one copy of a number of video feeds for distribution from a video head end that is coupled thereto e.g. via an ATM network. In such embodiments, the apparatus selectively transfers a copy of one of the video feeds being received, to each set-top box. Distribution of data flows in the apparatus can be implemented by a point to multipoint virtual circuit, although a change in a video feed being supplied to a subscriber requires tearing down the subscriber's old virtual circuit leaf and setting up a new virtual circuit leaf to the subscriber. The time delay and overhead associated with such virtual circuit changes are eliminated in certain embodiments by changing only an internal mapping.
