Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk storage medium suitable for use in, for example, a disk reproducing apparatus for reproducing data recorded on a data disk.

[0002]

2. Description of the Related Art In recent years, so-called CD-ROMs have become widespread.

On the CD-ROM, digital data such as characters (texts), images, and sounds can be recorded, but the currently available CD-ROMs mainly use the "characters". There are many things.

[0004] This is because computers have been developed mainly for characters, and the CD-ROM is also positioned as a peripheral device.

[0005] Further, the standard for CD-ROM (so-called Yellow Book) specifies only the physical format of data to be recorded, and does not specify the logical format (data specification).

That is, with the position that a large-capacity external storage device has been developed for a computer that has been developed mainly for characters, the standard has only specified the format of the data recording area.

[0007] In recent years, the demand for audio-visual devices has been increasing, and in this CD-ROM, the demands of users have been changed from images, voices, etc., instead of characters, and so-called multimedia systems have been required. Have been.

[0008] To meet such a user's demand, there is a so-called CD-I and CD-ROM XA.

The CD-I has a format for audio data, character data, and plate data, and also has operations of an OS (Operating System) and a CPU (Central Processing Unit) of a reproducing apparatus. Because of the provisions (see the Green Book), the search method is also unified, and the unified mutual search of the voice data, character data and illustration data can be performed.

[0010] However, this so-called CD-I is
It is not practical because of the delay in the spread of I playback equipment and the difficulty in developing software.

Therefore, there is a so-called CD-ROMXA as another means for responding to the user's request.

FIG. 10 shows the format of the CD-ROM XA.

In FIG. 10, a CD-ROM XA
Is an interleaved ADPCM (Adaptive Differential P
(ulse Code Modulation) Only the audio specifications are specified, and data recording for a maximum of 8 hours (monaural) and 16 hours (monaural) can be performed at levels B and C, respectively.

The recording of data at the level B has a sound quality comparable to that of, for example, FM broadcasting, and the sound quality is slightly degraded as compared with the recording by a CD-DA. The level C has a sound quality comparable to that of an AM broadcast, for example. However, if it is used for narration or the like, there is almost no problem in hearing.

Next, the interleaved ADPCM audio has a so-called real-time file configuration, so that real-time audio data and other data (including other audio data in addition to character data and illustration data) are included. (Simultaneous) playback is possible.

In the conventional CD-ROM, the format of PCM audio data is specified, but the PCM audio data cannot be interleaved and is arranged on another track.
Therefore, the PCM audio data, character data,
It is difficult to reproduce other data such as plate data in real time.

FIG. 1 shows an example of the configuration of this real-time file.
It is shown in FIG.

That is, as can be seen from FIG.
In the level B stereo mode, audio data is arranged every four sectors, and character data, illustration data, or another audio data is arranged in sectors between them.

In the stereo mode of level C, audio data is arranged every eight sectors, and character data, illustration data or other audio data is arranged in sectors between them.

Thus, voice data, character data,
Simultaneous reproduction with illustration data, different audio data, etc. is possible.

[0021]

However, the CD-ROM XA capable of simultaneously reproducing audio data, character data, and plate data as described above also has only the recording format of audio data specified as described above. The recording format of character data and plate data varied with the person creating the data disc. For this reason, a data search program is also developed independently by the person who produces the data disk, and the search method is different for each data disk, and the user must purchase search software for each data disk. In addition, the cost burden is large, and at the same time, it is necessary to learn the operation method for each of the search software, which is very troublesome.

[0022] In addition, these facts have had an adverse effect on the spread of the data disks and search devices.

Also, on the maker side, if search software is developed for each data disk to be sold, the development time, development cost, personnel cost, etc. are increased. It leads to cost increase.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a disk-shaped storage medium capable of mutually searching a plurality of media such as character data, plate data, and audio data.

[0025]

According to the present invention, there is provided a disk-shaped storage medium having a data area for storing main data and a management data area for storing management data for managing the main data. Along with having a data group management block corresponding to each of the plurality of data in the main data, each data group management block has a plurality of item data, and each of the item data corresponds to the item data on the display screen. Corresponding display position data, item name data indicating the name of the item data, and address data indicating an address in the main data corresponding to the item data, wherein the plurality of item data indicates a plurality of media. Each data in the main data is linked to the plurality of media by the data group management block. And wherein the Rukoto.

It consists of address data indicating the head address in the text data.

The position at which the icon is displayed is, for example, 4
The first and second bytes indicate the position of the X coordinate, and the third and fourth bytes indicate the position of the Y coordinate. How to record the display position of this icon
The same applies to the illustrated menu data pointer information 5 and another item reference data pointer information described below.

As described above, in this embodiment, the audio data is stored as the interleaved ADPCM audio data between the plate data in the body data. The sub-mode of the last sector of each audio data includes “End” indicating the recording end position of the audio data.
of Record ”bit is set.

It should be noted that this audio data is a so-called CD-D
The code of the audio data pointer information start identifier when recorded in the format of A is “1F47”, and the code of the audio data pointer information end identifier is “1F6”.
7 ".

The address data is divided into a track number, a start address and an end address. In this embodiment, the track number is the CD-DA
For example, a code “0002” indicating a second track having a fixed value is recorded. Then, the head address was recorded as a relative block number of the head address where the audio data was recorded, and the end address was recorded as the length of the audio data as a relative block number from the head of the track.

Next, among the item data 3 shown in FIG. 1, the illustration menu data pointer information 5 is pointer data for designating another image from the displayed image by referring to it. An illustration menu data start identifier (1F46) indicating the start of the illustration menu data pointer information 5, and an icon display as position data indicating a display position (recorded in XY coordinates) of an icon for selecting the illustration menu data pointer information 5 Position data, character data for displaying the data name of the illustration menu data pointer information 5 in characters, an illustration menu data end identifier (1F66) indicating the end of the illustration menu data pointer information 5, and the illustration menu data pointer information 5 Data group management blocks other than the data group management block in which There has been an address data indicating the leading address recorded.

Next, the separate item reference data pointer information 6 shown in FIG. 1 is pointer information for referring to new text data from the text data or the plate data in the display image. Another item reference data pointer information start identifier indicating the start of information 6 (1F4
2) Icon display position data which is position data indicating a display position (recorded in XY coordinates) of an icon for selecting the different item reference data pointer information 6, and a reference sentence name of the different item reference data pointer information 6 Character data to be displayed in characters, a different item reference data pointer information end identifier (1F62) indicating the end of the different item reference data pointer information 6, and the text data in the body data in which the different item reference data pointer information 6 is stored. It consists of the address data of the first address.

Here, the above description is about the data group management block 1 used when referring to another plate data, sentence data, or voice data from the plate data. The data group management block used when referring to audio data will be described with reference to FIG.

In FIG. 6, similarly to the data group management block 1, the data group management block 60 is also surrounded by a data group management block start identifier (1F45) and a data group management block end identifier (1F65). . Except for data corresponding to the illustration data pointer information 2 in the data group management block 1, the illustration group menu data pointer information audio data pointer information and another item reference data pointer information are included. Each of the data is separated by a line feed code (1F0A).

Since the structure of each data is the same as that of the data group management block 1, the description is omitted.

If a so-called block configuration is used in which each data is surrounded by the data group management block start identifier and the data group management block end identifier, it becomes difficult to reproduce only character data. However, in order to facilitate this, the character data may be placed outside the block surrounded by the data group management block start identifier and the data group management block end identifier.

Next, a data search method using such a data disk will be described with a specific example.

It is assumed that the above-mentioned data disc is used as, for example, a "United States guide" in which various data for introducing the history and geography of the United States are recorded.

This data disc contains images (illustrations,
Map, etc.), voice (narration, sound effects (BGM)
Etc.), so-called multimedia capable of displaying and outputting sentences (eg, commentary sentences).

First, when such a data disk is mounted on a reproducing apparatus and reproduction is designated, the reproducing apparatus transmits the main data according to the address data of the plate data pointer information 2 of the data group management block 1 shown in FIG. And read character data which is the name of the image to be displayed, character data of each item name of the searchable item data 3 and icon display position data of an icon for selecting the item data. Each is read and output.

As a result, for example, the display screen shown in FIG.
An illustration of a map of the United States as shown in (a) is displayed on the entire display screen, characters of the plate name "United States of America", and item names of searchable items "United States national anthem", Characters of “successful presidents”, “major cities in the United States”, “customs and customs in the United States” and an arrow-shaped icon 71 are displayed as an initial screen.

The icon 71 is operated by the user using a so-called mouse or the like.

For example, when "US national anthem" is selected from the search items shown in FIG.
1 is moved and designated so as to indicate the character of the "US national anthem". When this designation is made, the playback device reads and outputs the audio data from the address of the text data specified by the address data of the audio data pointer information 4 shown in FIG. 1, and outputs the data as shown in FIG. Then, control is performed such that the character of the "US national anthem" is displayed in the middle of the display screen or the like.

As a result, the performance of the national anthem of the United States is produced from the speaker or the like. In this case, the lyrics of the “US national anthem” may be displayed.

Next, assuming that the user operates the icon 71 shown in FIG. 7A and selects the item of "succeeding presidents", the reproducing device sets the address of the illustration menu data pointer information 5 shown in FIG. The data group management block specified by the data is reproduced.

FIG. 8 shows the configuration of this data group management block.

In FIG. 8, a data group management block 80 includes an illustration data pointer information 81 corresponding to the selected “successful president”, and voice data for outputting a narration corresponding to the “successful president” in voice. The pointer information 82 is composed of separate item reference data pointer information 83 to 85 for referring to a description such as a profile of each successive president such as George Washington, Lincoln, and Theodore Roosevelt.

The reproducing device reproduces the data group management block 80 to reproduce the text data designated by the address data of the plate data pointer information 81 corresponding to the “successive presidents”. In addition to reproducing and outputting the character data of the item names of the data 82 to 85, the control is performed so that the character of "the successive presidents" is displayed on the upper side of the display screen.

As a result, for example, the display screen shown in FIG.
As shown in (c), stone statues of faces such as "President George Washington", "President Lincoln", and "President Roosevelt" on Mount Rushmore in the United States are displayed as illustrations, and the profile of each president is referenced. Characters such as "George Washington", "Lincoln", and "Roosevelt" are displayed together with the icon 71 so as to be able to do so.

Then, when, for example, “Lincoln” is selected from the searchable items displayed on the screen, the playback device displays the text indicated in the address data of the separate item reference data pointer information 84 of the “Lincoln”. The description such as the profile of "Lincoln" is read from the address of the data and displayed on the entire screen.

Next, assuming that the user operates the icon 71 shown in FIG. 7A and selects the item "Main City in the United States", the playback device will set the illustration menu data 5 shown in FIG.
The data group management block specified by the address data is reproduced.

FIG. 9 shows the configuration of this data group management block.

In FIG. 9, a data group management block 90 includes an illustration data pointer information in which a head address and the like in text data in which illustration data for displaying “main cities in the United States” are recorded are recorded. 91 and separate item reference data pointer information 92 to 95 for referring to the description of each major city such as Los Angeles, San Francisco, New York, and Washington.

The reproduction device reproduces the data group management block 90, thereby reproducing the “main city in the United States”.
And reproduces and outputs the character data of the item names of the item data items 92 to 95, and outputs the character data of the "major city in the United States". Is displayed on the upper side of the display screen.

As a result, for example, the display screen shown in FIG.
As shown in (d), a map of the United States is displayed as an illustration, and the location and name of each major city are displayed as black circles.

Then, when, for example, “Los Angeles” is selected from the major cities indicated by black circles, the playback device returns to the main data indicated by the address data of the separate item reference data pointer information 84 of “Los Angeles”. The description of "Los Angeles" is read from the address and displayed on the entire screen.

Next, assuming that the user operates the icon 71 shown in FIG. 7A and selects the item of “US customs and customs”, the reproducing device sets the separate item reference data 6 shown in FIG.
Of the data group management block at the address specified by the address data of.

Although not shown, in this data group management block, the head address of the text data in which the description of the above-mentioned "US customs and customs" is stored is recorded. The sentence data corresponding to the “U.S. customs and customs” is read out and output from the address of the indicated body data, and the “U.S. customs and customs” is read out.
Is displayed, for example, on the upper side of the display screen.

Thus, on the display screen, for example, characters of “US customs and customs” are displayed on the upper side of the display screen.
Character data introducing "US customs and customs" is displayed on the entire screen.

As is clear from the above description, in the data disk according to the present embodiment, the data currently displayed in the block surrounded by the data group management block start identifier (1F45) and the data group management block end identifier (1F65) is included. Data pointer information 2 which is pointer data indicating the head address of the text data in which image data to be stored is stored, and item data 3 which indicates a searchable item
Is recorded, and the item data has an address of a corresponding data group management block, thereby enabling mutual search of the illustration data, the voice data, and the text data.

Further, since the data recording format and the data search method are unified, it is possible to reduce the cost by eliminating troublesome work such as developing a program for the search method for each software. Since it is not necessary to learn the search method every time, it is possible to deal with a search for a plurality of software by learning the search method once.

By unifying the data structure and the search method in this way, the versatility of software and playback devices can be improved.
