Abstract

A communication method and system are provided which enables the communication of data and television signals on a residential gateway network while avoiding the degradation of VDSL signals. This invention employs a new directional coupler that permits coupling between input and output ports, but only limited coupling to a television port.

Claims

1. A residential data communication system, comprising:

(A) a residential gateway providing a communication signal;

(B) a television receiving a video signal, wherein said video signal is derived from said communication signal;

(C) a directional coupler receiving an entry signal, a gateway signal and producing a television signal, wherein said gateway signal is derived from said residential gateway and wherein said entry signal is derived from a network interface device.

2. A directional coupler, comprising:

(A) an entry point;

(B) an input port electrically connected to said entry point;

(C) a coupler device electrically connected to said input port and to an output port and to a coupled port,

(D) a gateway point electrically connected to said output port;

(E) a filter, having a first and a second connection, wherein said first connection is electrically connected to said coupled port; and

(F) a television point electrically connected to said second connection of said filter.

3. A method for coupling communication signals, comprising:

(A) receiving a gateway signal;

(B) coupling said gateway signal to an network data signal;

(C) selecting television signals; and

(D) coupling said selected television signals to a television port.
