DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a VTR control technique. In particular, it is a device for controlling the playback speed or still image playback position of a VTR.

[0002]

FIG. 4 shows a conventional computer and a CRT.
3 is a control screen of the control device according to the first embodiment. 20 is a tape counter, 21, 22, 23 and 24 are operation switches and indicators, and 25 is a playback speed controller. In the control device configured as described above, the pointing device called a mouse is operated to move the fifteen mouse pointer displayed on the CRT display to the cursor 26, press the switch attached to the mouse, and further switch the mouse. By moving the mouse to the right or left while pressing, the cursor 26 moves, and the VTR can reproduce at the designated speed.

[0003]

However, in the conventional method, each time the playback speed is changed, the user moves the mouse pointer to the cursor, presses the switch, and further moves the mouse to move the mouse pointer to the point of the desired speed. Since the complicated operation of carrying is required, the person who operates is always C
There is a drawback that the user has to operate while watching the RT and cannot concentrate on the screen of the VTR.

[0004] In view of the above, the present invention requires that the operator operate the V
An object of the present invention is to provide a control device capable of controlling a reproduction speed or a still image reproduction position while watching a reproduction screen of a TR.

[0005]

The present invention comprises a VTR, a computer, a pointing device, and a CRT display.
The VTR and the computer are connected by a serial control signal, and a program for controlling the VTR, the CRT display and the pointing device is incorporated in the computer,
This is a control device of an audio / video recording / reproducing device for controlling a VTR reproduction speed or a still image reproduction position by giving an instruction to a computer using the search dial mark and the jog dial mark displayed on the RT and the pointing device.

[0006]

According to the present invention, the operator can operate the VT with the above configuration.
The player can control the playback speed or the still image playback position while viewing the R playback screen.

[0007]

FIG. 1 is a system configuration diagram showing one embodiment of a control device of an audio / video recording / reproducing apparatus according to the present invention. In FIG. 1, 1 is a player VTR, and 2 is a recorder VTR. A video tape is included in each of the VTRs 1 and 2, and only the necessary portions of the video tape image and sound in the player VTR 1 are copied to the video tape in the recorder VTR 2. And
It is a system that makes useless works. Reference numerals 3 and 4 denote monitor televisions for monitoring video and audio of VTRs 1 and 2. 5 is a computer, 6
By incorporating the program written on the floppy disk of the above, the program operates according to the program. Reference numeral 7 denotes a CRT for displaying the operation status of the computer 5. Reference numeral 8 denotes a pointing device called a mouse, and a user gives an operation instruction to the computer 5 by using the pointing device. The VTRs 1 and 2 have 5 computers and serial control signals 9 and 10
And is controlled by a computer 5. Since the computer of No. 5 operates according to the program written on the floppy disk of No. 6, the CR of No. 7
The display of T, the operation of the mouse 8 and the operation of the VTRs 1 and 2 are all determined by the program written on the floppy disk 6. Therefore, the operation of the example of the program will be described below mainly on the display of the CRT screen.

FIG. 2 is a graphic display of a CRT. 11 is a control display block of the player VTR.
Reference numeral 12 denotes a control display block of the recorder VTR. 13A is a search dial of the player VTR,
A 14A shog dial is arranged therein. 13
B and 14B are a search dial and a shog dial of the recorder VTR. The playback speed of the VTR is controlled by using the search dial and the jog dial. All these operations are performed using the mouse 8 in FIG. 1 and the mouse pointer 15 in FIG. Next, the VTR shown in FIG.
The operation will be described with reference to a control operation explanatory diagram. Although the reproduction speed of the VTR is written around the search dial in FIG. 3 for ease of explanation, this is not always necessary. When the mouse pointer 15 is moved into the frame of the search dial 13 and the right button 19 of the mouse 8 is clicked, the search dial marker 16 moves one step to the right. If the left button 18 of the mouse 8 is clicked, the search dial marker 16 moves one step to the left. When the buttons 18 and 19 are simultaneously clicked, the search dial marker 16 is forcibly set to S.
It returns to the position of TILL. VTR is 16
As a result, the playback is performed at the speed indicated by the search dial marker, and as a result, the FO can be freely operated only by operating the buttons 18 and 19 without particularly viewing the CRT screen display.
The speed can be controlled from WARD 7 times to REVERSE 7 times.

Next, the operation when the mouse pointer 15 is moved into the frame of the jog dial 14 will be described. When the right button 19 of the mouse 8 is clicked and released immediately, V
The TR sends one frame in the forward direction. If the left button 18 of the mouse 8 is clicked and released immediately, one frame is sent in the reverse direction. Further, when the mouse 8 is moved left and right while clicking the left or right button, the mouse pointer stays in the 14 jog dial and does not move. Instead, the 17 jog marker moves to the left and right distance of the mouse 8. Rotate left and right accordingly. Jog marker 1
Since the position of 7 corresponds to the position of the tape of the VTR,
The moving amount of the mouse 8 matches the moving amount of the tape. For this reason, even in a VTR in which the controller cannot send a response immediately after sending a control signal, the position of the scene in the tape can be almost grasped by moving the mouse 8 to the left and right. Can be searched quickly.

[0010]

As described above, according to the present invention, the CRT
Just move the mouse pointer to the search dial once and look at the screen, and then control the playback speed in the same way as with a pure hardware controller. VT
There is an effect that the user can concentrate on the R playback screen.

Further, when the mouse pointer is moved to the jog dial, the moving position of the video tape moves in accordance with the moving position of the mouse, so that a quick still image search can be performed as if the user directly touched and controlled the tape. There is.

As described above, both of them have extremely high practical effects.
