Abstract
PURPOSE: To simplify the constitution of the device, by forming the blank section by disusing the video signals in the intervals of the synchronous signals and then inserting the data into this blank section in order to record both the video and synchronous signals onto the common medium while keeping the synchronism between the video signal and the data.
CONSTITUTION: Mixture signal producing circuit 12 produces the mixture signals of the frame address signal and the video digital mixture signal row in which the data is inserted into the blank section of the video signals disused in the 1H intervals, and then supply the mixture signals to VTR1. The output of VTR1 is applied to reproduction terminal 43, and the video signal is separated from the data through scan-type signal selecting circuit 45 and gate circuit 46. At the same time, separation 47 is given between the horizontal and vertical synchronous signals. Then the data of the frame address designated is written into memory 55, and the signal read out of memory 55 is supplied to recorder 66 after D/A conversion 62.
