Abstract

PURPOSE:To display a designated address on a cathode ray tube even if no disc is in a reproducing state by providing a synchronizing signal generating means generating the synchronizing signal of a television signal. CONSTITUTION:A video information signal is reproduced from a disc 1 with a pickup device 2, an amplifier 3, a demodulator and a video signal processing circuit 6 and the like. A code signal demodulating circuit 9 demodulates a code signal in a reproducing signal. An operating means 13a generates an optional code signal with the operating key. A character generating circuit 10 generates a character signal in response to a demodulated code signal or an operated code signal. A synhronizing signal generating circuit 14 generates a synchronizing signal of a television signal. A synchronizing signal switching circuit 16 switche a reproducing synchronizing signal and a synchronizing signal from the circuit 14, and a switching means 15 switches a reproduced video information signal and a signal from the circuit 14 and these switchings are interlocked. An adding means 8 superimposes an output of the switching means 15 on the character signal.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an information recording + J-1 disk (hereinafter referred to as Twister and IIf) image generator fff, and in particular, information recording/
The present invention relates to a Tisuf-mounted FJ/I system which has a function of superimposing characters, numbers, etc. related to this information on both-side video information from the disk and displaying it on a video tube I-.

Although FIG. 1 is a block diagram without showing an example of a small device, a conventional example of the present invention will be briefly explained based on FIG.

The data recorded on the disk 1 is picked up by a pickup device 2 based on the principle of capacitance, and amplified to an appropriate level by an amplifier circuit 3 in the next stage.
The signal is then subjected to processing such as frequency characteristic correction, and then input to the FM demodulator 4. In the FM demodulator 4, the CFM demodulated signal is sent to the video signal and the carrier sub-day! '(,-1,
! ; and a code indicating an address, etc., but each of these signals is sent to the videotape 71 and the processing circuit 6.
and audio signal processing circuits. The signals input to the audio signal processing circuit 6 are subjected to FM detection after only the sub-signals are extracted, and subjected to noise reduction processing. After receiving the processing according to the command from 12, the output mAir2o is outputted to 21.

On the other hand, the first signal input to the video processing circuit 6 is transferred to the digital camera (the screen is removed, and the signal format of the possible signal format is transferred to the television receiver). '3(
After being converted into a TV signal (hereinafter referred to as 1-call), it is manually input to the squelch circuit 7. The squelch circuit 7 sets the playback device to the playback state according to a command from the microcomputer 12 and turns the videotape 71 on.
It functions to guide the signal from the trust processing circuit 6 to the adder circuit 8 or to cut it off. The reproduced TV signal from the video processing circuit 6 is added to the A character information signal from the character generating circuit 10 in the adding circuit 8, and then output to the video A output terminal 11. 1'[] from the disc containing the separated reproduced composite synchronization signal and code signal in the signal processing circuit 6: The raw video signal is input to the code signal demodulation circuit 9, where the lf raw video signal is input to the code signal demodulation circuit 9. The code I1-; such as address information included in the vertical retrace interval is separated and demodulated, and the input composite synchronization signal is separated into horizontal synchronization borrow and vertical synchronization Ig1 signal υ.

The code demodulated by the code signal demodulation circuit 9 is input to the microcontroller 12, where it is processed.
J is inputted to the character generation circuit 10, which generates a character signal corresponding to, for example, address information recorded on the disc, ie, the time (minutes: seconds) indicating the length of the disc, or a chapter number. The output signal of the character generating circuit 10 is input to the adder circuit 8, where it is superimposed on the live TV signal and displayed on the TV receiver via the output terminal -r11.

The microcomputer 12 receives and processes command values from the operation switch circuit 13, code signals recorded on the disk, and other information signals, and outputs appropriate command information in response to the received information. 11 is responsible for controlling each part of the +I+:/l device.

・v-)' A character signal from the rougher generation circuit 10, for example, a playback address signal from a disk, can be displayed or erased on the receiver by the operation switch circuit 13. ~9-1
When a desired address is specified by the user using the 0 key, etc., and a so-called cue command is issued to start playback from that specified position, the address is specified as desired.

Regardless of whether υ is displayed on or erased from the cathode ray tube, the reproduced video information is displayed in the display state. It is set to be displayed. Further, when the key-in of the specified address is completed and a cue command for the specified address is input, the pickup device starts moving, and at the same time, the reproduced video information and the specified address information are read.

Furthermore, when the cueing of the specified address ends, the meet state of the endogenous video information is released at the 11.1 point, and the 1 ellipse raw address signal is displayed according to the display/erasure state of the operation switch circuit 13. I'm going to be + M-made. In the conventional example described above, the designated address cannot be displayed on the cathode ray tube of the receiver unless the disk is in the birth state, so for example, the disk is attached to the 111 cow device f77 and the disk is born from the beginning of chapter 3 and then restarted. ;1. 11, '1
