PURPOSE:To know accurately the recording location, etc. of a program by continuously outputting plural codes which are sent in time series by a clock pulse by the clock pulse of an optional frequency. CONSTITUTION:The information of a disk 1 is reproduced by means of a pickup of a pickup circuit 2 and an MFM-demodulated through an FM modulator 3 and a decoder 4. An audio signal is outputted from an output terminal 5 and a video signal is outputted from another output terminal 8 through a memory 6 and a DA converter 7. A time code and a chapter code from the decoder 4 are supplied to data holding circuits 12a-12d through a clock pulse (a), a shift register 9, synchronizing signal detectors 10a-10d, and a data fetch controlling circuit 11. On the other hand, clock pulses of frequencies which are sufficiently smaller than the clock pulse (a) are sent from a terminal 13 to the control circuit 11 and the data holding circuits 12a-12d and both the codes are outputted from terminals 14a-14d in time series. Therefore, the recording location, etc., of a program can be known accurately. |
