Abstract

PURPOSE:To view an reproducing picture even with a receiver other than a specified one when plural television recerivers are connected to a TV signal input cable by flowing an output signal from a video recording and reproducing machine inversely through the TV signal input cable, as well via a hybrid circuit. CONSTITUTION:In case of viewing a normal TV video, a signal from the input cable 3 is viewed via the hybrid circuit H4 with the receiver 2. The recording and reproducing machine is 1 composed of a recording and reproducing circuit H5, a demodulator DEM 6, and a recording circuit 7, and a converter CONV 8 applies modulation to the unused channnel of the receiver 2, and a switch 9 changes over the output of the reproducer 1 to a signal being recorded or to a signal being reproduced from a reproduction circuit 10. In such a constitution, signals are outputted to not only to the receiver 2 but to the cable 3, hence reproducing picture can be viewed by other receivers, as well, sharing the cable 3.
