Abstract

PURPOSE:To remove the initial interruption of a succeeding program practically by forcing not to actuate a succeeding instrument until the program of a preceding instrument practically ends. CONSTITUTION:A video signal is inputted to a video signal detecting circuit 13 and an end signal detecting circuit 14 and a video signal switching circuit 15 and an audio signal switching circuit 16 are switched by a signal from the circuit 13. A start/stop control circuit 17 is actuated by an AND signal between the output of the circuit 14 and the output of the circuit 13 and a start signal is outputted. Therefore, the video signal and the audio signals 1, 2 stop at the output of the end signal from the 1st laser disc player LDP10 and only the signals expressed as SEDEL and END on the disc player are outputted to the video signal. The 2nd LDP11 is started by the end signal and a video signal is outputted to switch the circuits 15, 16. Consequently, the initial interruption of a trailing program is not porformed.

Description

[Detailed Description of the Invention] Kokumitsu is a manufacturer of V'I-R, video disc players, etc. II! l! (g! This is about the self-driving type of amphibious equipment.

As a conventional automatic operation system for video playback equipment, the V-VR system shown in FIG. 1 is known. In this method, from the first video playback device, audio signals 1.2 and video signals A, i, 7. When the number Jj is output, the Δ-di 71ffi number 2 is used for the Q (number 3) which indicates the end of the program.

In other words, this Q signal is input to the Q signal detection circuit 4 of the automatic driving equipment 3, and the above Q (control from the E3 detection circuit 4 (+'j @ t, start signal generation circuit 5 and stop 4
The signal is input to the No. 3 generation circuit 6, and also sent to the video A signal switching circuit 7 and the A-D Δ signal switching circuit 8. The signal from the start signal generation circuit 5 is applied to the start/stop control circuit 9 of the second video playback device, and the signal from the stop signal generation circuit 6 (from the own video playback device) 1 start/stop control circuit 9. The time shift of 8 signals in this case is shown in FIG.

In other words, when the A-di A signal 2 (Q (:M)) is output to the first video reproducing device, the power of the second video reproducing device is turned on, and then the Q signal ends. At the moment,
Audi No. 443 1. When the video A signal ends, the first video reproducing device starts the rewinding operation, but when the Q signal is output at rAt, the power of the second video reproducing device is turned on. However, since there are variations in the activation time of the video Δ signal among video transmitters, the audio 711 code 1 of the
．． A second video is played before the video signal ends.

There is a drawback that there is a short interval between the output of Δ-D and $ and the switching of video A and audio A. Furthermore, since the A-D signal 2 is used for the Q signal, there is an additional restriction that the audio becomes monaural. The switching operation from the second video reproduction (molding 1) 11 to the first video reproduction (finished product) is also similar to IfQ.

This was done based on the circumstances of ``Number of Inventions'' - '11, so the preceding device was not allowed to start up the subsequent device until the actual program in 83 was completed, and when the video signal was output from the subsequent device. , the video J5 and audio horns are switched from the preceding device to the succeeding device, virtually eliminating the beginning of the subsequent B1' Durham, and also allowing A-D A13 to be used in multiple channels. This is an attempt to provide directions for automatic operation of video playback equipment.

To this end, the present invention provides multiple ll! A! The image reproducing device is operated continuously so that the program of the subsequent (firearm) is started immediately after the program of the preceding device is completed.
5, when the program of the preceding device is completed, turn on the power of the succeeding device, and after startup, detect that the video signal of the succeeding device is output, and switch the video and audio ]J from the preceding device to the succeeding device. It also sends out a control signal 011 to stop the preceding equipment.

Hereinafter, one embodiment of the present invention will be described with reference to the case of a J Ray disk player 17 shown in FIGS. 3 and 4.
.

Please explain in detail. In the figure, the symbol @i0.11 is a laser disc player (hereinafter referred to as Ll)P), which transmits A-11413 No. 1 and 2 and the video signal, respectively, to the audio signal switching circuit 16J5 and the same de-Δ signal switching circuit TB15. It is set to output via -(.

The video signal also includes an end signal (readout):
, j'3) are superimposed on the end point of P1' Dalam.

In actual laser discs, the encoded Phillips code is included in the video signal, so the above-mentioned end signal is not included at the end of the program according to regulations. This end signal is sent to the rS on the disk display 17, for example.
When superimposed on something expressed as a logo such as Eθ[El, ENDJ, etc., J: Yes. Therefore, the video signal is input to the video signal detection circuit 13 and the end signal detection circuit 14, and the video signal switching circuit 15 and the audio signal switching circuit 1G are switched by the signal from the video signal detection circuit 13. . Also, by ANDing the signal from the end signal detection circuit 14 and the signal from the video signal detection circuit 13, the start/stop control circuit 17 operates, and a start signal is issued.

The time chart at this time is as shown in Figure 4. When the LDP of '31 outputs the end in@, the video signal, A-DIO (No. 8 1.2) ends, and only the rs[DEi, [ENDJ expression signal] is output to the video Δ. When the second LDP is activated by the end number 13 and the video (number 3) is output, this is detected and the video signal switching circuit 15 and the A-dio signal switching circuit 16 are switched, so the start of the next program is started. To break (Yonai)

Conversely, due to variations in startup time,
The display display times of sEDEl and ENDJ change (No.) After that, the pickup of the preceding device moves to the initial position, and then the power supply is turned off.

According to the present invention, when switching from a preceding device to a succeeding device, the beginning of the program of the succeeding device can be avoided, and the channel of the A-day A signal can be changed to the Q-trust. Since the channel is not used for the first time, the effect is that a small number of channels can be used.
