<p>The signal transmission system includes concentratedly arranged various kinds of electronic apparatus (4 to 10) capable of transmitting information such as audio and/or video informations and provided with a main control means (3) for controlling those apparatus and auxiliary control means (25,26,27) arranged in a plurality of rooms (20,21,22) via cables (19) so that above information can be properly watched and heard through the above main control means (3). Transmission of information is processed in a short time and a possibility of controlling even an electronic apparatus ( 5,9) having no means for receiving control signals through wire is provided by having the signals outputted in parallel or in parallel and in series, when control signals for demanding transmission of information properly are fed to the various kinds of electronic apparatus from the auxiliary control means (25,26,27) through the main control means (3). <IMAGE> <IMAGE></p> |
