Abstract: A two-way cable television broadcasting system wherein a single coaxial cable is used to deliver TV and FM programs to many subscribers with each subscriber having a specific allocated band of frequencies for reception of any desired television or FM program and where each subscriber can independently select the program desired to be seen and/or heard which will be delivered to the subscriber over an allocated band of frequencies. The subscriber drops from said coaxial cable are so arranged that they descend in frequency along the length of the feeder cable. Automatic switching of any incoming program to any drop is achieved by means of converting all incoming channels to a common I.F. frequency at an amplifier or control station and then deconverting said frequency to the desired outgoing band of frequencies.
