Signal transmission system with quicker response and with parallel and serial outputs

Claim 1

A signal transmission system in which a plurality of electronic apparatuses which transmit audio and/or video information are concentratedly installed and in which said audio and/or video information from said electronic apparatuses are viewed and listened to in a plurality of remote spots, comprising: (1) first control means connected with said plurality of electronic apparatuses and having means for supplying a first control signal in parallel or in series to each of said electronic apparatuses so that said electronic apparatuses are controlled by their respective first control signal; (2) second control means for receiving said audio and/or video information through said first control means from said plurality of said electronic apparatuses and transmitting a second control signal for controlling said first control means so that said first control means supplies said first control signal to a respective electronic apparatus of said electronic apparatuses; (3) transmitting means for connecting said first control means and said second control means, for transmitting the audio and/or video information from said first control means to said second control means and for transmitting said second control signal for controlling said first control means from said second control means to said first control means; and (4) converting means, provided in said first control means, for converting said second control signal from said second control means to said first control signal and for supplying said first control signal to said respective electronic apparatus in parallel or in series corresponding with said respective electronic apparatus that is being supplied with said first control signal; wherein said converting means includes memory means for storing said first control signal that is associated with said second control signal and switching means controlled by a central processing unit (CPU) for selectively switching said first control signal, said first control signal that is associated with said second control signal either is converted through said memory means to a format different from said second control signal prior to being supplied to said respective electronic apparatus or is directly connected to said respective electronic apparatus.
