The present invention relates to an apparatus and method for screen searching of a video cassette recorder, and more particularly, to an apparatus and method for searching a screen using a screen stored by storing a desired scene in a memory.

In the conventional screen search method, when a tape is stopped at a desired scene, the counter is zeroed at the scene to be searched and the stop button is pressed at the point where the counter becomes zero.

This method is shown in FIG. Briefly, if the reset key is pressed in step 101, the count becomes 0 in step 102 and if it is a 0 stop key (step 103), the process proceeds to step 104 and starts rewinding and continues if it is not 0 stop key. The stop key was moved to step 106 to stop the tape and play back the picture.

This conventional screen search method has a drawback in that only one screen can be selected and the reset key is accidentally stopped when it is not desired.

The screen searching apparatus and method of the present invention are to solve the above disadvantages.

SUMMARY OF THE INVENTION An object of the present invention is a retrieval apparatus for searching a predetermined screen, which is a video circuit 3 for processing a video signal and a signal connected to the video circuit 3 to display a video signal on a screen. In the video cassette recorder screen retrieval apparatus having an OSD circuit (4) for processing and a microcomputer (11) for controlling the deck (7), it is connected to the memory (10) and the video circuit (3) and is analog. A / D converter 8 for converting a signal into a digital signal and storing it in the memory 10, and a digital signal connected to the memory 10 and the microcomputer 11 and stored in the memory 10 A D / A converter 9 for converting to video data, and connected to the OSD circuit 4 and the D / A converter 9 to the OSD circuit 4 in accordance with a signal from the microcomputer 11; Switch means for switching the output signal from the output signal from the D / A converter 9 [5] A video cassette recorder screen retrieval apparatus is provided.

Still another object of the present invention is to provide a screen searching apparatus for a video cassette recorder, characterized in that a plurality of screen data are stored in the memory (10).

Another object of the present invention is to provide a screen searching apparatus for a video cassette recorder, characterized in that the A / D converter 8 and the D / A converter 9.

Still another object of the present invention is to provide a screen searching method of a video cassette recorder which reproduces the screen by pressing a reset key when designating a predetermined screen, and converting the screen into digital data when the predetermined screen is designated. Storing the converted digital data in the memory 10, converting the stored data into a video signal, and switching the video signal and an output signal from the OSD circuit 4 by switching And a step of outputting a storage screen, and transferring the tape to a position of a corresponding screen when the outputted storage screen is a desired scene.

Another object of the present invention is to provide a screen searching method of a video cassette recorder, characterized in that the plurality of storage screens.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated, referring drawings.

2 is a circuit diagram showing an apparatus according to the present invention. The intermediate frequency signal received through the antenna is input to the IF circuit 1, the audio signal is output to the audio circuit 2, and the video signal is output to the video circuit (3). Both the audio signal from the audio circuit 2 and the video signal from the video circuit 3 are transmitted to the preamplifier 6 and amplified by a control signal introduced from the microcomputer 11 via the data 7. Then, it is returned to the audio circuit 2 and the video circuit 3 again. The audio signal is audio output from the audio circuit 2.

The video signal is output from the video circuit 3 and input to the OSD circuit 4 and simultaneously to the A / D converter 8, which is composed of, for example, an A / D converter. The OSD circuit 4 sends an image data signal for display on the screen to the switch 5. In addition, the video signal provided to the A / D converter 8 is converted into an analog signal into a digital signal, and transmitted to and stored in the memory 10. In this case, preferably, a plurality of image data are stored in the memory 10 so that the user can easily search the screen. The stored digital image data is output from the memory 10 and transferred to the D / A converter 9, for example, which is an A / D converter, where the digital image data is converted into a composite image signal. The video signal output from the OSD circuit 4 and the composite video signal output from the D / A converter 9 are selectively switched by the switch 5 in accordance with the output signal from the microcomputer 11 to output video. .

The operation will now be described with reference to FIG.

In retrieving a predetermined video image from a tape on which video and audio data are recorded, pressing the reset key (step 301) converts the predetermined video image into digital data (step 302). At this time, the converted data is stored in the memory 10. Preferably, the image data stored in the memory 10 is a plurality of image information. If a plurality of image data stored in the memory 10 is to be searched (step 304), the process proceeds to step 305, and if no search is desired, the process proceeds to step 306 to wait and returns to the first step 301. If a search is desired in step 304, the stored data is converted in the order of the stored data (step 305), and the switch is switched to output the storage screen (step 307). If the screen output in step 307 is a desired scene, the process proceeds from step 308 to step 309 to transfer the tape to the position of the corresponding screen. Continue to print the screen. When the tape transfer is completed in step 309, playback can be started in step 311 to easily position the scene desired by the user in the correct position. As described above, the present invention does not need to memorize numbers when there are several scenes to be searched, and does not need to be repeatedly searched until the scenes come out as in the case of index search, and several can be stored according to the memory capacity. After looking through the screen, you go directly to the location, so you can easily use the effect.
