Abstract

PURPOSE:To always reproduce a correct address code even when drop-out has occurred, by comparing two same address codes which have been superposed and recorded on a display picture, and outputting a code which has been operated from the preceding address which is stored, at the time of noncoincidence. CONSTITUTION:Two same address codes having serial numbers are extracted at every picture which is superposed and recorded on a display picture detected from the video disk 1, etc. by the pickup 2, the signal processing device 3, the code sampling circuit 4, etc. They are compared by the pattern detector 9, and the selector 10 outputs a code from the circuit 9, which has been stored in the memory 8, in accordance with a selection signal outputted by the detector 9 at the time of coincidence. On the other hand, in the event of noncoincidence, through the detector 9, the selector 10 selects an operation code which has added ''1'', to the code of the preceding picture, stored in the delay memory 11. Accordingly, even when drop-out has occured, a correct address code can be reproduced at all times.
