Abstract

PURPOSE:To realize various complicated operations with a simple bar code by recording bar code interpreting information to interpret the bar code for which an application programmer himself defines processing operations on an optical disk. CONSTITUTION:The bar code information to interpret the bar code for which the processing operations are defined by the application programmer himself is recorded on an optical disk 11. When the disk 11 is set to a reproducing device, a control means 15 transfers a recording position on the disk 11, where the bar code interpreting information is recorded, to a reproducing means 12. The means 12 reproduces the recording position for the bar code interpreting information on the disk 11 and transfers a reproduced signal including the bar code interpreting information to an extracting means 13. The bar code interpreting information is extracted from the signal and stored in a storing means 14. The bar code, which is recorded on a bar code recording medium 18 paired with the optical disk 11, can be interpreted under this state, and operation control for the disk 11 can be executed by an instruction from a user.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an optical disc for recording and reproducing information and a reproducing apparatus therefor.

BACKGROUND OF THE INVENTION In recent years, optical disks such as video disks and compact disks capable of recording large volumes and high density have been developed, and various applications thereof have been proposed.

One such application is laser discs.

Laser disks are CAV image recording media with a playback time of 30 minutes on one side and a capacity of 54,000 still images, and are also used for education, illustrated books, etc. due to their random access function. When used for these purposes, complex operations such as frame-by-frame access and repeated playback of short sections are required.

Since it is impractical to operate this using a remote control, a method has been proposed in which a laser disc is combined with conventional paper media and controlled using a bar code.

This optical disc reproducing apparatus is called a laser barcode system, and uses, for example, a barcode called interleaved 2 of 5 (ITF).

The format of the code is that the first digit is a category character, and the next 14 digits record the start/stop frame number, screen 0N10FF, audio mode, and checksum. In other words, simple basic operations such as playback, stop, frame advance, picture search, etc., and simple combinations thereof can be performed using the barcode. and the number is l
It is about O. (ASCII, Vol. 11, No. 12, December 1987, pp. 308-309 (ASCII, Vol. 11)
．． #12 Dec, 1987 pp308-309 The above-mentioned conventional laser barcode system will be described below with reference to the drawings. The laser barcode system uses a laser disc and a publication on which a barcode is printed as a pair, and will be explained using an illustrated animal encyclopedia as an example.

FIG. 2 is a block diagram of a conventional laser barcode system. In FIG. 2 ζζ, 21 is a laser disc player, 22 is a barcode controller, 23 is a barcode scanner, 24 is a publication on which the barcode is recorded,
25 is a television.

The operation of the laser barcode system configured as above will be explained.

First, a laser disc containing an animal encyclopedia is set in the laser disc player 21. Next, the user publishes (picture book)
24 and select, for example, the item lion, and use the barcode scanner 23 to trace the barcode printed next to the explanatory text. The read barcode information is converted into player commands by the barcode controller 22 and transferred to the laser disc player 21. The laser disc player 21 operates according to commands,
In this example, the positions recorded about the lion on the laser disc are played back continuously, and the environment in which the lion lives and the way it attacks its prey are shown on TV 25 with video and narration.
is shown.

Problems to be Solved by the Invention - However, the above system uses a fixed barcode with predetermined operation details.

For this reason, as the application software recorded on the disk frequently interacts with the user, and the content of the interaction requires complex processing, the operations that can be performed with a single barcode also become more complex. Despite this requirement, a single barcode can only perform simple operations and its number is small. Furthermore, even if the number of operations is increased in response to complex operations, the number of barcodes is fixed in the system, so there is a problem that the number of operations is limited.

In view of the above-mentioned problems, the present invention records barcode interpretation information for interpreting barcodes in which the application creator defines processing operations on an optical disk, in order to realize complex and various operations even with a finite number of barcodes. To provide an optical disk playback device that interprets a barcode read from a barcode recording medium using barcode interpretation information read from an optical disk, and allows a user to use the barcode to select and play back the operation intended by an application creator. It is.

Means for Solving the Problems In order to solve the above problems, the optical disc of the present invention is played back by an optical disc playback device equipped with a barcode reading means for reading a barcode from a barcode recording medium and converting it into an operation code. An optical disc characterized by recording barcode interpretation information describing the operation contents of an optical disc playback device corresponding to the above, and the playback device includes a playback means for playing back a specified position on the optical disc indicated by a playback command, and a playback signal. an extraction means for extracting barcode interpretation information from the barcode interpretation information; a storage means for storing the barcode interpretation information; an output means for controlling the output of information other than the barcode interpretation information of the reproduced signal; A barcode reading means reads a barcode and converts the barcode into an operation code, and the operation code is interpreted by barcode interpretation information stored in a storage means and reproduced according to the interpreted content or content predetermined by the reproduction device itself. control means for controlling the means or output means, the reproduction means reproduces the barcode interpretation information recording position of the optical disk, the barcode interpretation information extracted from the reproduced signal by the extraction means is stored in advance in the storage means, and the barcode interpretation information is stored in advance in the storage means. The control means interprets the operation code converted from the barcode by the code reading means using the barcode interpretation information, controls the reproduction means or the output means according to the interpreted content, and outputs the controlled reproduction signal by the output means. It is something.

The optical disc and its playback device of the present invention, with the above-described configuration, enable an application creator to create a barcode that defines processing operations by himself/herself, and interpret the read barcode from the optical disc. The user uses the barcode to select and play the action intended by the application creator, so even if the same barcode is played, the barcode interpretation information on the disc will be different if different discs are played. Even simple barcodes can perform a wide variety of complex operations. Application creators can also create their own barcodes that define their own processing operations, making the application more flexible.

Embodiment Hereinafter, an optical disc and its reproducing apparatus, which is an embodiment of the present invention, will be described with reference to the drawings.

FIG. 1 is a block diagram of an optical disc and its reproducing apparatus, which is an embodiment of the present invention. In FIG. 1, 11 is an optical disc of the present invention, 12 is a reproduction means, 13 is an extraction means,
14 is a storage means, 15 is a control means, 16 is an output means, 1
7 is a barcode reading means, and 18 is a barcode recording medium.

The operation of the optical disc and its reproducing apparatus configured as above will be explained.

An optical disc 11, which is an embodiment of the present invention, records barcode interpretation information for interpreting a barcode in which an application creator has defined a processing operation at a certain predetermined position, and the barcode recording medium 18 is a pictorial book, etc. For example, a book is printed with a barcode that defines processing operations.

Set the optical disc 11 in the playback device. Then, the control means 15 transfers the recording position on the optical disk 11 where the barcode interpretation information is recorded to the reproduction means 12. The reproduction means 12 reproduces the barcode interpretation information recording position of the optical disc 11 and transfers the reproduction signal containing the barcode interpretation information to the extraction means 13. The barcode interpretation information is extracted from the reproduced signal by the extraction means 13 and stored in the storage means 14.

In this state, the optical disc playback device can interpret the barcode recorded on the barcode recording medium paired with the set optical disc, and can operate and control the optical disc according to the barcode command from the user.

While looking at the barcode recording medium 18, which is an illustrated book of animals, the user selects, for example, the section on lions, and uses the barcode reading means 17 to trace the barcode printed next to the explanatory text. The barcode is read by barcode reading means 17, converted into an operation code, and sent to control means 15. The control means 15 retrieves the barcode interpretation information from the storage means 14, interprets the operation code according to the information, and controls the reproduction means 12 and the output means 16 according to the interpreted content. The output means 16 sends the controlled reproduction signal to the television,
indicate. As a result, in this example, various operations can be performed, such as sequentially playing back various lion ecology records recorded discretely in multiple locations on an optical disc, and displaying lions from various locations at once using a split screen. This can be done with one barcode.

Next, when the optical disc containing the plant encyclopedia is set in the reproducing device, the barcode interpretation information in the optical disc 11 is stored in the storage means 14, as described above.

Therefore, even if the barcode in the plant encyclopedia is the same as the barcode in the lion section of the animal encyclopedia mentioned above,
Because the information to be interpreted is different, for example, the growth process of a sunflower can be sequentially played back, or completely different actions can be performed.

Effects of the Invention As described above, the optical disc and its playback device of the present invention, with the above-described configuration, enables an application creator to create a barcode that defines processing operations by himself/herself, and reads the read barcode from the optical disc. The read barcode interpretation information is used to interpret the barcode, and the user uses the barcode to select and play the action intended by the application creator, so even if the same barcode is played on different discs, the barcode interpretation information on the disc may be different. In contrast, even a finite number of simple barcodes can perform a wide variety of complex operations.

Application creators can also create their own barcodes that define their own processing operations, making the application more flexible.
