IPC: H04N7/173
Filed: 1986-07-19
Abstract: PURPOSE:To surely extract the pulse string signal of subscriber's address by inserting said signal in a television signal transmitted from a central equipment by AM demodulating the FM signal of a voice carrier. CONSTITUTION:The designated data signal of a still picture or a moving picture information inputted to the central equipment 1 form respective terminal equipments 2, is subjected to a combiner diplexer 8, and received and processed by a reception device 9, then outputted to a controller 4, and thus the designation from the equipment 2 is recognized. In case of transmitting a still picture information, A still picture transmitter 5 outputs a video signal to a high-frequency modulator 6 under the control of he controller 4. The modulator 6 has an AM modulation function for video signal and an FM modulation function for sound signal, and converts its own input to the video frequency of a CATV channel and outputs to an address addition device 7. The device 7 AM modulates only sound FM signals with the subscriber's address, and outputs the resulting signals to the diplexer 8 together with the video signals. In case of a moving picture, the signals are applied with the scrambling of a synchronizing signal compression system.
