摘要：A signal distribution network in which signals are distributed via a primary signaldistribution path. Television signals are transmitted in a first frequency band, telephone

signals are transmitted in a second frequency band, and data signals are transmitted in athird frequency band. Bidirectional terminal adapters are connected to each endpoint ofthe primary signal distribution path. The terminal adapters connect to end user deviceswhich receive signals from the primary signal distribution path. In addition, the terminaladapters connect to signal sources which provide the signals to be distributed via theprimary signal distribution path. In one embodiment, television signals received from aCATV television network are received by a television distribution module. The televisiondistribution module has one or more tuner/converters each of which tune to a desiredchannel, modulate the desired channel onto at least one predetermined distributionchannel, and provide the signal to the primary signal distribution path via thepredetermined distribution channel. The total bandwidth of the primary signaldistribution path can be substantially lower than the total bandwidth of the

communication links providing the sources of signals entering the network. As such, theprimary signal distribution path may be implemented utilizing a single pair of wires.
