<p>PROBLEM TO BE SOLVED: To attain simultaneous recording and simultaneous reproduction which are free of a lag by allowing respective video and audio recording and reproducing mechanisms to start or stop recording operations or reproducing operations at the same time at the same time when an instruction is given from an instructing means. SOLUTION: When a 'simultaneous recording' switch is selected on a console panel 30, an operation control microcomputer 28 recognizes that and writes the choice of 'simultaneous recording' operation to a dual-port RAM part 26. A video and audio signal 58 is inputted to a VCR a22 and the signal when an analog signal is converted by an analog-digital conversion part 36 into a digital signal, which becomes a frame-by-frame image signal. The image signal and a time code signal are synchronized and put together by a signal composition and magnetization part 44. As the image signal written to a system control microcomputer 34 of a VCR b24, a signal composition and magnetization part 46 of the VCR b24 uses the time code signal generated by a time code generation part 40 of the VCR a22.</p> |
