Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Technical Field of the Invention) This invention automatically searches the screen of a video disc by recording a signal for searching the screen of the video disc on a digital recording medium. This invention relates to an automatic search method for video disc screens using a digital recording medium that is searchable.

(Technical background of the invention and its problems) Conventionally, information recording media for converting and recording information such as characters and figures into digital signals include magnetic tape, floppy disk 1, magnetic disk, CD-ROM, and IC.
Cards, optical cards, etc. are known, and information such as characters, figures, etc. is retrieved by reproducing digital signals recorded on these information recording media. However, when recording natural images including still images or moving images as digital signals on the above-mentioned information recording medium, the amount of information of natural images is orders of magnitude larger than that of characters, etc. This has the disadvantage that it is either impossible or, if possible, can only be stored in a very small amount.

Furthermore, when searching for information, the user may want to view information such as characters, figures, etc. and information about natural images at the same time, rather than individually. This can be easily understood by imagining photographs and pictures inserted into general books.

Optical or capacitive video discs have emerged as other information recording media, and these video discs can hold one minute of video and audio on each side, or 54,000 still images. You can record what you do.

Furthermore, video discs have a convenient search function that allows desired information to be read out in a short access time through random access.

However, even on such video discs, conventionally it has not been possible to simultaneously view information such as characters, figures, etc. and natural pictures. moreover.

It was also not possible to automatically edit or search information such as characters, figures, etc. manually input from other information recording media to match the screen of the video disc.

(Object of the invention) This invention was made under the above circumstances,
It is an object of the present invention to reproduce character 1 graphic information from various widely used character 1 graphic digital recording media, and to search video disk screens recorded corresponding to this character 2 graphic information. An object of the present invention is to provide an automatic search method for a video disc screen using a digital recording medium, in which the screen of a video disc is automatically searched by control number 18 for the purpose of the present invention.

(Summary of the Invention) The present invention relates to an automatic search method for a video disc screen using a digital recording medium such as a GO-ROM or an optical card. The screen of the video disk is automatically searched by a control signal for searching the screen of the video disk recorded in correspondence with one piece of graphic information.

(Embodiment of the Invention) FIG. 1 is a block diagram showing an embodiment of an apparatus for realizing an automatic search method for a video disc screen using a digital recording medium of one character and one figure according to the present invention.

In this method, a floppy disk is used as a digital recording medium, the floppy disk is inserted into a floppy disk reader 1, and digital information of one character and one figure recorded on the floppy disk and a control signal of a video disk are read. Then, the digital information is converted into a predetermined format via a computer 2 such as a microcomputer, characters and figures are displayed on a display 3 such as a CRT, and a video disc control signal is sent to the remote control section of the video disc player 5 by wire. Alternatively, the relevant natural images can be displayed on the display 6 by transmitting them wirelessly and automatically searching the video disc screen. Also, the character 9 can be manually entered using a control device (for example, a keyboard) 4 connected to the computer 2.
It allows you to search for information about shapes.

In such a configuration, a user first prepares a floppy disk and a video disk, and sets them in the floppy disk reader 1 and video disk player 5, respectively. Here, image information (still images and moving images) in encyclopedias and the like are recorded as natural images on a video disk, and characters 9 and 9 corresponding to the above image information are recorded on a floppy disk.
An example will be explained in which a graphic (in this case, a description of a car) and a video disc control signal are recorded. This image information may be not only an encyclopedia but also a complete collection of art works, a complete collection of literature, a photo collection, a catalog collection, a complete comic collection, etc. In this case, the content recorded on the floppy disk may also include texts corresponding to this image information. Prepare.

Next, in order to search for information on the floppy disk, when the desired content (page or column of car description in the encyclopedia) is selected using the control device 4 connected to the computer 2, the display 3 connected to the computer 2 is selected.
character.

The figure (description of the car) is displayed, and this character 1
A video disc control signal corresponding to the graphic information is sent to the video disc player 5, and the video disc player 5 searches the set video disc for a screen corresponding to the character 9 graphics mentioned above, and displays the image (encyclopedia) on the display 6. Still images or videos of printed cars)
is displayed.

Figure 2 shows characters read from a floppy disk using a single display.

A method of superimposing graphic information and image information automatically retrieved from a video disc player 5 on a display 6 using a conventionally known method (here, a car explanation customer is inserted into a picture of a car) It is. In this case as well, the search is automatically performed by making a selection using the control device 4 in the same manner as described above.

In this way, simply by selecting the recorded content on the floppy disk, a screen is automatically selected from the video disk and an image is displayed.

(Modification of the Invention) In the above embodiment, a floppy disk was used as the digital recording medium, but a magnetic tape may be used and reproduced by a magnetic tape reader. Alternatively, a magnetic disk may be used and reproduced by a magnetic disk reader. Furthermore, a CD-ROM may be used for playback on a CD-ROM reader, an IC cart may be used for playback on an IC card reader, and an optical card may be used for playback on an optical cart reader. It may also be played back. Then, instead of the above-mentioned digital recording medium, digital information of one character and one figure corresponding to the screen of the video disk and a control signal for searching this video disk screen are recorded on the video disk, and these signals are read by a computer. Processing may be performed to search the video disc screen. In this case, the above-mentioned digital information recording medium and a separate reader for reading it become unnecessary.

Figure 3 shows an example of a device that implements this method.
This device uses displays 3 and 6, a video disk player 5, and a control device 4, which have the same configuration as explained in FIG. digital information and video disc control signals. The computer 7 stores the digital information of the characters 5 and the video disc control signals reproduced by the video disc player 5, and when the desired content (for example, the automobile page of an encyclopedia) is selected using the control 4, the computer 7 displays the information on the display. 3
A character 1 graphic (for example, a description of a car) is displayed on the screen, and a video disc control signal corresponding to this character 1 graphic is transmitted to the video disc player 5, so that the above-mentioned characters can be read from the video disc.

A screen corresponding to the figure is searched, and an image (a still image or a moving image related to automobiles in the encyclopedia) is displayed on the display 6. Further, by applying the configuration explained in FIG. 2, the display is made into one display as shown in FIG. The automatically searched image information may be superimposed and displayed on the display 6.

(Effects of the Invention) According to the method for automatically searching a video disc screen using a digital recording medium of the present invention, a reproduction device for a digital recording medium of one character shape and a video disc player are connected via a small computer such as a microcomputer. You can automatically search the screen just by doing this, and the screen of the video disc is automatically selected as soon as you select the information of the 3 characters, so there is no need to perform a troublesome screen search using index matching.

There is an advantage that the figure screen and the natural image screen can be viewed at the same time.
