Abstract
A signal distribution cable network in which a plurality of information channels are defined by respective carrier frequencies and serve a plurality of local signal sources (SS1, SS2, SS3) and signal destination receivers (SR1, SR2, SR3) connected to the network. The network has a channel allocation controller (CT) which operates on request to allocate temporarily an unused channel for transporting signals from a local signal source (SS1, SS2, SS3) to a signal destination receiver (SR1, SR2, SR3). The controller (CT) transmits tuning signals to the local signal source and the signal destination receiver to tune them to the carrier frequency of the allocated channel. The channel allocation excludes channels which normally carry signals from external signal sources.
