Title:
INFORMATION TRANSMISSION METHOD AND INFORMATION TRANSMITTER
Document Type and Number:
Japanese Patent JP3808678
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure transmission of an information signal in the case of handling multi-channel signals with respect to a technology employed for transmitting an audible tone signal and an information signal attended on it at the same time to a machine.
SOLUTION: The information transmitter is provided with a plurality of channels through which the audible tone signal (1) is transmitted, the audible tone signal (1) on each channel and other signal (2) are electrically synthesized for each channel, the synthesis electric signal synthesized electrically for each channel is outputted to external field as a sound signal and transmitted to a transmission line for each cannel as the synthesis electric signal, a receiver side receives the synthesis electric signal, the signal (2) is extracted from the synthesis electric signal and the extracted signal (2) operates the machine.
