Abstract

PURPOSE:To realize the simultaneous acquisition of both the video and aural signals by giving the time axial compression to the aural signal for the simultaneous recording and reproducing with the still picture image. CONSTITUTION:The time axial compression is given via time axial compressor 12 to the signal of aural signal source 10 in order to store the signal within the recording time of the video signal. This compressing action is attained by increasing the reading speed more than the writing speed by means of the memory. This compression signal is compounded at compounding circuit 14 via FM modulator 13 along with the video signal of FM modulator 11 and then shaped into nearly the rectangular wave through limiter 15 to be applied to optical modulator 2. A number of video signals of the still picture and aural signals with the time axial compression given are prepared previously to be transmitted continuously after the synchronization is once secured at first. Thus the both signals of many frames are recorded continuously. In ths case of the reproduction, the wiring is given into the memory of the time axial expander and then the reading is given in a lower speed than the writing velocity to perform the time expansion. And then the demodulation is carried out through the demodulator.
