Abstract
PURPOSE: To simplify the constitution for the recorder/reproducer by carrying out the writing and reading of the memory via the vertical synchronous signal in case the input analog video sinal is stored in the memory after A/D conversion.
CONSTITUTION: The digital video signals obtained by giving 3-equal divisions to the video signal are written into memories 11A∼11C via writing signal WR. With switch SW1 turned on, vertical synchronous signal PV inverts FF23 through gate 22. The write signal WR is delivered to terminal Q' of FF23, and this output is applied to memories 11A∼11C. The output is delivered through gate 25 via the next vertical synchronous signal to reset FF21. At the same time, the write signal does not exist with FF30 set, and the still picture video signals read out of memories 11A∼ 11C are supplied to the video intermediate frequency amplifier. Then switch SW2 is turned on, and thus FF30 is reset to the original state.
