[Field of Invention]

The present invention relates to a method for enabling the use of a Video Index Search System as a Video Address Search System. Specifically, in the present invention, the video index search signal recorded on the video tape is stored in a conventional microcomputer RAM without using the video address search system integrated circuit, and the title of the contents recorded in the RAM on the on-screen display. To display on the monitor.

[Background of invention]

In the prior art, as shown in FIG. 1, a video index search signal is recorded on a video tape during a video index search system operation. The video index search operation causes the user to first record the video index search signal before the content to be recorded on the video tape, and to search for the recorded video index search signal corresponding to the content. For example, if the current videotape is in Korean, and you want to see society, you must press +3 because society is at +3 from the current Korean position. If the current videotape is in arithmetic position, press +2 because you are in the position of +2 from the current position when you want to see society. If you want to see Korean when the current videotape is in social position, you should press -3 because Korean position is -3 from the current position. In the same way as described above to find the content recorded on the video tape to play the content.

That is, to search the contents recorded on the videotape using the conventional video index search system, the position of the place to look for is changed according to the position of the current videotape. For example, if your current location is Korean and you see society, it is +3. If you look at society, your current location is arithmetic. If you see society, it is +2. As described above, the position where the contents to be searched are changed according to the current position, so the user must know all the places recorded on the videotape and the position of the position to be viewed at the current position. It was a problem.

[Purpose of invention]

In order to solve the above problems, an object of the present invention is to record a video index search signal on a video tape when a video index search system is operated, to store the position of each video index search signal in an internal RAM of a microcomputer, and the user can easily record the video index search signal on the video tape. The present invention provides a method of displaying a title of recorded content on a videotape on an on-screen display so that the content can be easily identified and browsed.

[Summary of invention]

As shown in FIG. 2, the present invention sequentially records 1, 2, 3,... From the beginning when recording each content together with a video index search signal on a video tape. In this way, the title and the serial number are stored in the microcomputer's RAM and the contents recorded in the microcomputer's internal RAM are displayed on the monitor screen using the on-screen display. In addition, the present invention by pressing the key to enter the number of the title to be watched and the number displayed on the monitor screen, the microcomputer calculates the position of the current videotape content and the videotape content desired by the user to record the content desired by the consumer A method for automatically finding the location of a recorded videotape.

[Description of Specific Example of the Invention]

Hereinafter, a method of using the video index search system of the present invention as a video address search system will be described in detail with reference to FIGS. 2, 3, and 4.

The present invention provides a servo integrated circuit (2) for recognizing a video index search signal recorded on a video tape, a system control microcomputer (4) and a system control microcomputer (4) for receiving and detecting a video index search signal from a servo direct circuit (2). On-screen display integrated circuit that receives the video index search signal from the timer microcom (6), which stores the video index search signal number and title in the internal RAM, and receives data about the video index search signal number and title from the timer microcom (6). (8) and a monitor (10) for receiving data on the video index search signal number and title from the on-screen display integrated circuit (8) and displaying them on the screen in characters.

Referring to the operation of the present invention configured as described above using the flowchart of FIG.

When recording a video index search system, it is determined whether or not it is in a video index search system mode. If it is not in the video index search system mode, real time setting (RTS) is performed. In the video index search system mode, the video index search recording is performed, and it is determined whether the video index search system recording is completed. If the video index search system recording is not completed, the video index search system recording is performed again. If the video index search system recording is completed, it is determined whether or not the on-screen display video index search system title is set. If the on-screen display video index search system title is not set, real-time setting is made. If the on-screen display video index search system title is set, the number and title are recorded and judged as complete. It is not completed and record the number and title again. When complete, record the number in RAM of the timer microcomputer, then record the on-screen display title in RAM and make real-time settings.

The video index search system search determines whether it is in video index search system mode. If the video index search system mode is not set, do the real-time setting. In the video index search system mode, the number is set and the setting is completed. If the setting is not completed, set the number again. After the setting is completed, check the number of the current videotape content position and subtract the current position number from the setting number arithmetically. Determine whether the result of subtracting the current position number from the set number is positive (+). If the result is not positive, that is, negative, the video tape is rewound and it is determined whether the video tape movement is completed. If the move is not completed, rewind again. When the move is complete, play it back and make real-time settings. If the result of subtracting the current position number from the set number is positive (+), the video tape is advanced at high speed and the video tape is judged to have completed moving forward. When the videotape movement is completed, play it back and set it in real time.

The effects of the present invention are as follows. Record the video index search signal on the video tape when the video index search system operates, store the location of each video index search system in the internal memory of the timer microcomputer, and use the on-screen display to display the number and title of the recorded content on the video tape on the monitor screen. By displaying, the video tape recorder user can easily check the recorded contents and also have the effect of browsing. In addition, the video index search signal is recorded on the video tape and the address is set using the microcomputer's internal RAM, so it can be used like a video index search system, so that the video index search system can be conveniently operated.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the invention and therefore such variations and modifications are within the scope of the appended claims.
