Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video disc search system.

Readable information recording media such as catalogs and guidebooks contain several photographs and drawings that correspond to explanatory texts, guide texts, etc., but due to space limitations, they cannot be published. There is a limit to the number of photos, drawings, etc.

Therefore, in recent years, video disks that can record a large amount of image information have been used to store image information related to each section of text such as explanatory text and guide text in large numbers of still images, videos, or sets of these. By recording the image information corresponding to each text category from the video disc and displaying it on the monitor when viewing a guidebook, etc.
Systems that provide a large amount of image information for each text category have been developed and are in use.

Conventionally, in this type of system, when reading image information corresponding to each text section of a guidebook etc. from a video disc, address information such as frame numbers stamped twice for each text section in the guidebook etc. is transmitted to the remote control. A search system was adopted in which the corresponding image information was retrieved by key input from the operation panel.

However, in such a search system, in order to find the viewing name, it is necessary to check the frame number for each text category in the guidebook, etc., then move to the operation panel and input the frame number, which makes it difficult to read the guidebook. Since the reading must be temporarily interrupted, there is a problem in that the correlation between the image of reading a guidebook or the like and the image of looking at a monitor screen is severely impaired.

1 The present invention has been made in view of the above-mentioned points.
It is an object of the present invention to provide a video disc retrieval system that allows correlation between images.

In the video disc search system according to the present invention, when searching for a video disc on which image information related to each text is recorded for each text segment on a predetermined readable information recording medium, each text segment is recorded on a predetermined readable information recording medium. A bar code indicating the recording position address of the corresponding image information on the video disc is recorded for each disc, and this bar code is read by a reading means, and the corresponding image information is searched based on this read information. .

Branch - 1 Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In FIG. 1 showing a video disc playback device, a video disc 1 includes many types of video information as image information, such as moving images, and furthermore, prior to these image information, desired image information is stored to facilitate retrieval of desired image information. program information is recorded.

When the disc is used as an image file for a guidebook 20 about living things, the image information recorded on this video disc 1 is different for each text section of the guidebook 20, for example, for each item, and the explanatory text for that item is different. At the start and end portions of each video information, a start frame number and an end frame number are attached to a predetermined control code as address information indicating the recording position on the disc.

Furthermore, an identification code indicating that the program information is program information is attached to the program information in order to distinguish it from image information.

On the other hand, as shown in FIG. 2, the guidebook 20 contains code information such as barcodes (hereinafter referred to as barcodes) indicating the start frame number and end frame number of image information corresponding to each item recorded on the video disc 1. (collectively referred to as a code) 21 is printed for each item. As this barcode 21, start frame number 21
8 and the end frame number 21b, parameters 21c for freely setting the operation mode, such as playback speed, are also printed. Furthermore, at the bottom of the same page, for example, to rPL8Y, "P to tlsE J, rS
TEP REVEItSEJ, “schoILL”
A bar code 22 representing an operation mode such as J, [5TEP FOWAR[l J, etc.] is printed on each page as an operation command.

Recorded information on the disc 1 is read by a pickup 2. The read RF multiplied signal is demodulated by the FM demodulation circuit 3 and supplied to the monitor 4, as well as the signal separation circuit 5 and the CPU.
<Central processing unit) 6 is also supplied. The signal separation circuit 5 separates and extracts control signals such as a frame number and an identification code in a predetermined control code along with a horizontal synchronization signal and a vertical synchronization signal from the demodulated output and supplies them to the CPU 6. A memory 7 such as a RAM (Random Access Memory) is connected to the CPU 6, and when the CPU 6 detects an identification code indicating program information from the demodulated output, it reads the next data. This program information is stored in the memory 7.

The CPLI 6 further performs various operation controls in response to commands from the operation unit 8, and when a frame number obtained by decoding the barcode read by the barcode scanner 9 with the decoder 10 is input, The search control device 11 is driven to search the disc 1 for image information corresponding to the frame number.

Next, the CP of the video disc search system according to the present invention
The execution procedure by U6 will be explained according to the flowchart of FIG.

It is assumed that the program information for searching recorded on the disc 1 has already been stored in the memory 7, and in this state, the barcode 21 of the guidebook 20 is read by tracing by the viewer's barcode scanner 9. When it is determined that the barcode has been input (
Step 1), then it is determined whether the barcode information is a command indicating the operation mode (Step 2), and if it is command information, the command processing is executed.Step 3), Step 1 Return to

If it is determined in step 2 that it is not a command input, it is determined whether or not it is a so-called address block input in which a start frame number and an end frame number are input as a pair (step 4). If so, put a marker at the end frame number address in step 5).
Furthermore, the start frame is searched (step 6), and the player enters the appropriate invasion play mode and starts the playback operation of the player (step 7). If it is determined in step 4 that it is not an address block input, that is, if only one frame number is input, the frame is searched (step 8), and the process returns to step 1 to wait for barcode input.

During play, that is, during image playback, when a barcode indicating an operation mode is input (step 9), command processing corresponding to that barcode is executed (step 10), and then in step 11 the playback up to that point is performed. If it is determined that it is necessary to continue playing the image information, step 9
If not, the process returns to step 1 and waits for barcode input.

When the playback operation continues and it is determined that the marker set in step 5 has been reached, that is, the end frame has been reached (
In step 12), the reproduction of the image information of the block specified by the barcode input is completed, and the process returns to step 1.

In this way, in the search system according to the present invention, the barcode 21 printed for each item of the guidebook 20
By tracing with barcode scanner 9,
Since the image information corresponding to the explanatory text for each item can be quickly searched, the user's eyes can be easily moved between the guidebook 20 and the monitor 4.
This means that it is possible to search for desired image information without damaging the correlation between the reading image and the image image.

In the above embodiment, a guidebook is used as the readable information recording medium, but the present invention is not limited to this, and may be a pamphlet, a catalog, or a book such as an encyclopedia. Further, the image information is not limited to moving images, and still images may be a combination of moving images and still images.

As explained above, according to the video disc search system according to the present invention, by reading the barcode recorded for each text category on the readable information recording medium, the corresponding image information is searched. This eliminates the need for the user to move their eyes to the operation panel and enter address information, which is required in the past. Information can be searched quickly.
