A switch(SW2) switches a switch(SW1) into a field memory(31), to store an output of a signal processor(10). An edit key input unit(70) selects a frame, time, and a chapter demanded by a user among signals reproduced from a laser disk(11). A memory(80) stores contents corresponding to a key inputted from the edit key input unit(70). An OR gate(OR1) supplies the external video signal or the reproduced signals of the laser disk(11) to the switch(SW1). When a synchro edit signal of a micro computer(50) is output, an OR gate(OR2) outputs a synchro edit signal for recording an external input signal or the reproduced signals to a system 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a syncro edit device of a laser disc player (hereinafter referred to as LDP), and more particularly, to an LDP synchro which allows a user to edit only a desired screen with a simple key operation. It is about an editing apparatus.

FIG. 1 shows a conventional synchro editing apparatus, which shows a system for editing from system 1 to system 2. FIG.

Here, when editing from system 1 (VTR 1) to system 2 (VTR 2), a synchro edit signal is output to system 2 along with the video signal according to the state (play or stop) of system 1.

Then, it is recorded in the system 2 according to the state of the output synchro edit signal (high: recording, low: pause).

The synchro edit signal is a signal recorded on the tape as the synchro edit key on the camcorder is pressed when shooting with the camcorder.

However, in the synchro editing function as described above, the recording of the system 2 varies depending on the state of the system 1, but there is an inconvenience in that the user has to artificially manipulate it.

Also, editing from LDP to VTR could not be made.

Is connected to the switch OR2 and the microcomputer 50, and outputs an external input signal or a laser disk 11 reproduction signal when the synchro edit signal of the microcomputer 50 is output. Synchro for recording on Iowa gate (OR2) for outputting a call is in sync LDP editing apparatus is further provided.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

2 is a configuration diagram of the present invention, which comprises a pickup 12, a demodulation unit 13, a CCD 14, a caption processing unit 15, and an OSD unit 16 and reproduced by the pickup 12. (11) a signal processing unit 10 for caption processing and OSD processing of a signal, an amplifying unit 20 for amplifying the output of the signal processing unit 10, and an output of the signal processing unit 10 according to a user's selection A field memory 31 for storing and outputting the memory, an amplifier 32 for amplifying the output of the field memory 31, and an output of the signal processor 10 for the amplifier 20 or the field memory 31. A switch SW1 for switching to the ") side, a decoder 40 for decoding the output signal of the CCD 14 of the signal processor 10, and a video signal output from the decoder 40 to control the synchro edit signal. A microcomputer 50 outputs an external video signal input unit 60 for inputting an external video signal to the decoder 40, and the switch SW1. Switch SW2 for switching to the memory 31 side to memorize the output of the signal processing unit 10, and an edit key input unit for selecting a desired frame, time, chapter, etc. among signals reproduced from the laser disk 11; 70, a memory unit 80 for storing contents corresponding to a key input from the editing key input unit 70, the switch SW2 and the microcomputer 50, and connected to an external image signal or the laser disk. An external input signal at the time of outputting the synchro edit signal of the microcomputer 50 connected to the OR gate OR1 for supplying the reproduction signal of the electronic device 11 to the switch SW1 and the switch SW2 and the microcomputer 50. The laser disk 11 is configured by adding an oragate OR2 for outputting a synchro edit signal for recording the reproduction signal to the system 2. The system 2 for recording the signal reproduced by the LDP is a conventional VTR system, and the image output from the microcomputer 1 and the first and second amplifiers 20 and 30 that control the system as a whole. The Y processing unit 2 and the C processing unit 3 for processing the signal separately into the luminance signal (hereinafter referred to as Y) and the color signal (hereinafter referred to as C), and the Y processing unit 2 and the C processing unit 3 Y / C mixing unit 4 for mixing the outputs of the P / A output as a video signal and amplifying unit 5 for amplifying the output of the Y / C mixing unit 4 and recording the result in the recording head CH1. do.

In the present invention configured as described above, first, the signal recorded on the laser disk 11 is read by the pickup 12, demodulated through the demodulator 13, and then input to the CCD 14.

The CCD 14 detects the edges of the horizontal and vertical synchronization signals of the video signal, detects the difference in edge values caused by the difference in the rotational error caused by the rotation of the disk, and transfers the charges constantly. The video signal passed through 14 is inputted to the field memory 31 through the caption processing unit 15 and the OSD unit 16 by the switch SW1 or to the system 2 via the amplifying unit 20.

The video signal reproduced by the laser disk 11 and the video signal through the CCD 14 and the video signal from the external video signal input unit 60 are decoded by the decoder 40 and input to the microcomputer 50.

In the case of the CLV type disc recording the normal recording state at the linear speed, the video signal is unstable in the pause state, so that the video signal is stored in the field memory and then outputted to the video output stage to obtain a clean screen. .

That is, when the switch SW2 is input in the above state, the user's desired part can be stored in the field memory 31 through the oragate OR1. Therefore, in this case, since the external video signal from the external video signal input unit 50 or the video signal of the laser disk 11 is stored in the field memory 31 and outputted to the system 2 through the amplifying unit 32, You can record in a pose like the picture you took.

When the user inputs a desired chapter, frame, time, etc. through the edit key input unit 70, the corresponding setting contents are stored in the memory unit 80, and the microcomputer 50 stores the setting contents stored in the memory unit 80. Only the relevant part is taken from the decoder 40 and played, and the synchro edit signal is output to the system 2 through the oragate OR2 such that the system 2 is in a recording or pause state according to the setting contents stored in the memory unit 80. do.

That is, the oragate OR2 outputs a synchro edit signal for recording an external video signal or a laser disk 11 signal to the microcomputer 1, when the synchro edit signal of the microcomputer 50 is 'high'. If the switch SW2 is 'ON', the image output from the amplifier 32 is recorded via the field memory 31. If the switch SW2 is 'OFF', the output image of the amplifier 20 is recorded. do.

As described above, the present invention simply selects a desired part through the edit key input unit of the LDP that the user must manually operate when performing the synchro editing function in which the recording of the system 2 is changed according to the state of the conventional system 1. By selecting and recording only the selected part in the VTR, editing of the desired part is simplified, and the recorded content on the disc can be recorded in a pose state like a picture taken with a still camera using the field memory.
