PURPOSE:To correct the code error of a time address to obtain correct address data by forecasting plural continuous time address values, and correcting the error on the basis of the forecasted values. CONSTITUTION:A reproducing time address signal is inputted from a reading part 4 to an input terminal 10 and supplied to a serial/parallel converter 11. The serial/parallel converter 11 separates time address signal of respective digits for ''hour'', ''minute'', ''second'', and ''frame'' individually and outputs in parallel these signals to a time address correcting circuit 12H, a minute address correcting circuit 12M, a second address correcting circuit 12S, and a frame address correcting circuit 12F respectively. The frame address from the serial/parallel converter 11 is supplied to a memory 133 out of cascaded memories 131-133 and stored in the memory 133. Respective storage address values FR(N-2), FR(N-1) and FR(N) are supplied to a forecasting circuit 14 respectively and the address value FR(N-1) is supplied also to a correcting circuit 15. |
