Signal transmitting device and signal receiving device

A signal transmitter which is connected to a signal receiver via a transmission line, comprising:

• a time-base compression means for time-base-compressing a first signal;
• a multiplexing control signal generator for generating a multiplexing control signal on the basis of a second signal;
• a signal multiplexing means for multiplexing the time-base-compressed first signal, the second signal and a third signal, employing the multiplexing control signal generated by the multiplexing control signal generator, and outputting a multiplexed signal;
• and
• a signal transmitting means for transmitting the multiplexed signal to the signal receiver.

A signal receiver which is connected to a signal transmitter via a transmission line, comprising:

• a first receiving means for receiving a multiplexed signal in which a time-base-multiplexed first signal, a second signal, and a third signal are multiplexed, from the signal transmitter;
• a second receiving means for receiving a multiplexing control signal from the signal transmitter;
• a demultiplexing means for demultiplexing the multiplexed signal received by the first receiving means into the first and second signals, employing the multiplexing control signal received by the second receiving means;
• and
• a time-base decompression means for time-base-decompressing the first signal obtained by the demultiplexing means.
