摘要： A coaxial network suitable for the distribution of video signals between a number of video cameras and signal monitors is described. The network includes a central symmetrical star splitter 1, each port of the central splitter being either terminated or connected to a respective asymmetrical splitter 7. A number of sockets are attached to each asymmetrical splitter 7. The network is such that the performance of each asymmetrical splitter is insensitive to the number of sockets attached to the asymmetrical splitter which are being used, terminated, or left open circuit.

摘要： A signal distribution system is described for the interchange of signals between a number of appliances such as television receivers 13, 14, video recorders 15 and surveillance cameras 16, 17, 18. The appliances are connected via a passive star splitter 1. A controller 11 allocates frequency channels to each appliance. The system is such that signals within a particular frequency channel injected into the system by one of the appliances may be received by any receiver appliance connected to the system to which has been allocated the same frequency channel.
