Abstract

A Node '0' device for a Consumer Electronics Coaxial Bus (CXBUS) network is provided. The network has a plurality of internal cables coupled to a source of up-link signals located within a first frequency band. The up-link signals include first audio/video (A/V) signals (which may be digital or analog) and control signals. External cables provide second A/V signals located within a second frequency band. An active input section is coupled to the internal cables. The input section individually filters and amplifies the up-link signals and combines the amplified signals. The input section provides a down-link signal path. A block converter coupled to the input section converts the first A/V signal from the first frequency band to the second frequency band, and provides the converted signals at its output port. A control channel regenerator coupled to the input section receives the control signal, generates a down-link control signal, and transmits the down-link control signal to the input section. An external cable distribution section is coupled to the external cables and to the source of second A/V signals. The external cable distribution section receives either the converted signals, the second A/V signals or both, and transmits the received signals to the external cables.
