Abstract

PROBLEM TO BE SOLVED: To improve the usability by enabling partial reproduction and output of data in one unit which is outputted at the same time or successively among recorded data. SOLUTION: Index data ('noun S', 'noun E', 'verb S$ b, 'verb E', etc.) showing part of data in one unit which is outputted at the same time or successively is added in the data. The reproducing device is enabled to extract a data part to be reproduced and outputted actually from the data of the one unit by using the index data and reproduce it. For example, speech data of 'I wake up early and got on a train.' are vocalized as 'I wake up and got on a train.' consisting of only the nouns and verbs.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to, for example, a CD-RO.
The present invention relates to a recording medium on which digital data is recorded, such as an M, an IC card, and a solid-state memory, and a reproducing device corresponding thereto.

[0002]

2. Description of the Related Art In recent years, electronic media such as CD-ROMs, which can record characters, voices, images, etc. as digital data, have become widespread. For example, in a form called an electronic book, a dictionary or a novel is published as a disc.

[0003]

By the way, even when such an electronic recording medium is used, the reproduced information is exactly the same as the recorded information, and should be output simultaneously or continuously, for example. It is not possible to select and reproduce only a required part from one unit of data.

For example, when voice information (such as a conversation voice) pronounced for a certain sentence is recorded, the reproduction operation is only to reproduce the voice normally, and for example, a modifier is abbreviated as a subject and a predicate. You can't just play it alone. In addition, even if you want to hear the conversation voice quickly and grasp the data contents roughly, the only way to hear it quickly is as a high-speed playback. I will end up.

The same applies to the case of displaying character data and the like, and when it is desired to roughly understand each sentence data, one unit of data (for example, one sentence displayed simultaneously) is partially reproduced. Since it is not possible, even if you want to grasp the contents easily, you have to read the displayed output sentences and so on.

[0006]

In view of the above problems, the present invention enables partial reproduction and output of one unit of recorded data which is output simultaneously or continuously. It is intended to improve the usability of digital data media systems.

Therefore, as a recording medium, index data indicating a part of the data is added to one unit of data that is output simultaneously or continuously.
As the reproducing apparatus, an extracting unit capable of extracting a data portion to be actually reproduced and output from one unit of data to be output using the index data, and reproducing only the data portion extracted by the extracting unit. A reproduction control means for outputting is provided.

For example, if the index data is added to each word or a character string forming a meaning in one sentence data, a shorter and meaningful sentence can be extracted by the selection by the index data. . In other words, it becomes possible to reconstruct the data by modifying the recorded data, and it is possible to expand the usage pattern.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, as an embodiment of the present invention, a disc as an electronic book and its reproducing apparatus will be described as an example.

FIG. 1 is a block diagram of a reproducing apparatus. The disc 1 as an electronic book is loaded into the disc driver 2 in the reproducing apparatus. The disk driver 2 has a spindle mechanism for rotating the disk 1 at a predetermined speed, an optical head mechanism for irradiating the disk 1 with a laser beam, detecting the reflected light to read the data recorded on the disk 1, and a spindle rotation. Also, a servo mechanism for executing various servo operations for optical head operation is installed.

The information read from the disk 1 by the disk driver 2 is subjected to various stages of decoding processing in the reproduction processing section 3 and is taken out as character information, image information, audio information and the like. The information thus extracted is stored in the RAM 5 under the control of the CPU 4. Information is read out from the RAM 5 as necessary under the control of the CPU 4, and the data to be displayed, that is, character information or image information is supplied to the display driver 6. Then, the display driver 6 causes the display 7 to execute the display according to the information content. The audio information is supplied to the audio output driver 8, subjected to D / A conversion processing and amplification processing, and supplied to the speaker unit 9 as an analog audio signal. Then, the sound is outputted from the speaker unit 9.

The operation unit 10 is provided with operation keys for the user to instruct the reproduction operation of the disc 1. For example, in addition to keys for instructing basic operations such as a play key and a stop key, a numeric keypad, an alphabet key, an input enter key, and the like are provided so that search information can be input. For example, by inputting a data number, a keyword, an initial letter, or the like of information to be read in the disc 1, the CPU 4 traces the directory structure constructed in the disc 1 and determines the address of the information to be read in the disc 1. Confirm. Then, the disk driver 2 is instructed to access the address and execute the data reading. The operation unit 10 is provided with other necessary keys, and the CPU 4 operates the operation unit 1
The required control is performed based on the operation information from 0.

Further, particularly in this reproducing apparatus, the operation unit 10
By setting the reproduction mode and executing the reproduction of certain data, special reproduction for partially performing reproduction output from the original data can be performed.

FIG. 2 shows the directory structure of the disc 1 as an electronic book. Data as the volume descriptor 30 is described on the innermost side of the disc 1. The volume descriptor 30 is
The basic data on the information content recorded on the disc such as the title of the disc (electronic book) and the author is written, and the logical structure information of the entire disc such as the address where the root directory 31 is described is also recorded. There is.

In the root directory 31, addresses for the sub-directory 32 and the files 34 ₁ , 34 _2, ... 34 n are written. Files 34 ₁ and 3
34 ₂ ... 34n corresponds to one document and indicates a data group in which information as actual contents is recorded. For the number of files to be formed and the method of dividing the data contents into files, refer to
It is decided according to the information content.

In the subdirectory 32, index information 3 used for searching information contents in the electronic book is stored.
The address where 3 is recorded is written. As the index information 33, data for a basic search operation is recorded. As a search method, prefix match search (search by entering the first letter or the first few letters), backward match search (search by entering the last letter or the last few letters), keyword search, menu search, data number search, etc. Is possible. Information for executing these searches is constructed as index information 33. For example, regarding the keyword, the address of the position where the keyword is actually recorded in the file is described. In addition, the address of the information is recorded according to the number set for each information for searching the data number.

Data such as actual voices / characters / images on the disk 1 are stored in the files 34 ₁ and 34 _2.
Although recorded as 34n, this voice / character data is indexed as
Data indicating each part is added in one unit of data that is output simultaneously or continuously.

This data format will be described with reference to FIG. 3 by taking the case of voice data as an example. It is assumed that voice data "I got up early and got on a train" is recorded as shown in FIG. 3 (a). This voice data is one unit of data that is continuously output as voice, and in a normal reproducing operation, the voice output "I got up early and got on the train" is output. The audio data is recorded on the disc 1 after the analog audio signal is converted into digital data, for example, in a state of being subjected to data compression processing.

The data recorded on the disc 1 is
One unit of audio data that has been compressed is subdivided, and index data is added to all or part of the subdivided audio data. For example, when index data indicating "noun" and "verb" is set in a sentence, the data becomes as shown in FIG. 3 (b). That is, the index "name S" indicating that the noun part begins before the voice data part "Iwa"
Is added, and an index "name E" indicating that the noun part ends is added to the end of the voice data part "Iwa".

Further, before the voice data portion "wake up", an index "verb S" indicating that the verb portion begins
Is added, and an index "verb E" indicating that the verb portion ends is added to the end of the voice data portion "wake up". Index data is similarly added to the "train" portion and the "ridden" portion.

In addition, the index data is "subject"
When it is set to indicate "predicate", an index "main S" indicating that the subject starts is added before the voice data portion "Iwa" as shown in FIG. An index "main E" indicating that the subject ends is added to the end of the voice data part "I". Then, an index "predicate S" indicating that the predicate part starts is added before the voice data part "I got on a train", and a predicate part is added at the end of the voice data part "I got on a train". Index that indicates the end "Predicate E"
Is added.

The disc manufacturer may set the index data and which part is associated with which index. In addition to “noun” and “verb”, indexes such as “adjective” and “conjunction” may be set. In addition to "subject" and "predicate", indexes such as "modifiers" may be added.

Further, in FIGS. 3B and 3C, the index data is added before and after the data portion to specify the target data portion.
You may make it add only to the front like (d) and (e). In this case, for example, index data "name" indicating that the noun part starts and data indicating the data length (bit number) of the noun part may be added.

FIG. 4 shows the operation in the case of performing special reproduction by the reproducing apparatus for the disc 1 having such index data. In this case, the special reproduction is to reproduce and output the recorded sound data as a short sentence that makes sense. Such reproduction will be referred to as data transformation reproduction.

An example will be given in which the user operates the operation unit 10 to reproduce the data shown in FIG. CPU4 is assumed to be data transformation reproduction,
When the reproduction of certain data is instructed, the disk driver 2 is controlled, and first, the data to be reproduced (in this case, the voice data "I got up early and got on the train") is read from the disk 1 (F101, F102).

Here, the index information added to the read data is confirmed and, for example, only the subject and the predicate are extracted (F103). In the case of FIG. 3C, the voice data “I got on a train” is constructed. Then, the voice data of only the subject and the predicate are supplied to the voice output driver 8 and output from the speaker unit 9 (F104).

As a result, the user originally hears the data "I got up early and got on the train" as a short sentence "I got on the train". That is, by continuing such reproduction, it becomes possible to listen to the audio data, which becomes long in time, in a short time while grasping the content to some extent.
For example, when it is desired to search for a desired reproduction position while listening to the reproduction sound, such a reproduction operation is convenient. Of course, it may be possible to reproduce only the subject or only the predicate. In other words, if you use only predicates, "I got up early and got on the train."
The data will be played as "I got on the train".

Further, the case of voice data has been described, but the case of character data is also effective. For example, it is possible to display and output only a noun from a long sentence, or transform it into a short sentence with only a subject and a predicate and display and output it.

In this embodiment, a read-only recording medium such as an electronic book has been described. However, when a user uses a recording medium on which data can be recorded, it is conceivable that the user can add index data. For example, when inputting accounting data, "Sales""Profit""Achievementrate"
Set indexes such as so that they can be input at the same time. Then, at the time of reproduction, it is possible to reproduce only the data regarded as “sales” from one unit of data.

As the recording medium of the present invention, a CD-ROM other than an electronic book, an IC card, a solid-state memory, game software, a communication electronic medium, etc. may be adopted.

[0031]

As described above, according to the present invention, the index data indicating a part of the data is added to one unit of data output simultaneously or continuously to the recording medium, and the reproduction is performed. Since the device extracts the data part to be reproduced and output from one unit of data to be output by using the index data and reproduces and outputs only the extracted data part, the original recorded voice is recorded. / Data such as characters can be transformed into short data and output, and the output data can be recognized to some extent by the user, so that data contents can be confirmed and searched quickly. Becomes,
This is a valid operation. Moreover, it becomes possible to create more diverse usage patterns.
