Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a storage medium having a plurality of storage areas distinguished by stored data such as a format, and a technique for reproducing data stored in the storage medium.

[0002]

2. Description of the Related Art In recent years, in addition to advances in semiconductor technology and the like,
The information compression technology has also greatly advanced and international media standards, such as MPEG1 and MPEG2, have been defined. Therefore, the standardization of storage media (storage media) for storing information has been actively performed. Recently, DVD (Digital Video
Disc) standardization has converged. On the other hand, CD
Also, standards that take multimedia into account have been actively proposed. A CD to which the multimedia is added is an enhanced CD.

An enhanced CD has two storage areas that are distinguished by a data format. One is an area where the same CD-DA (digital audio) data as an ordinary music CD is recorded, and the other is a CD-DA area.
-An area where data of the ROM is recorded. That CD-
Image data (including data encoded by the MPEG encoding method) such as a promotion video or a jacket can be recorded as ROM data.
For this reason, it has received a great deal of attention as a way to provide an enhanced way of enjoying a conventional music CD.

As is well known, enhanced CDs are roughly classified into three types depending on the format. The first is a type called a mixed mode, the second is a multi-session, and the third is a CD-ROM ready. Among these, the multi-session is different from the other types in that CD-DA data can be recorded on tracks 1 to 99 in the same manner as a music CD. You can listen to music at. This is why multisession is the hottest of several types of enhanced CDs. The multisession is what is commonly called CD-EXTRA.

[0005] In recent years, the number of personal computers (hereinafter, referred to as personal computers) has been greatly increased, and CD-ROM devices are becoming standard equipment in the personal computers. In a personal computer equipped with a CD-ROM device, CD-EX can be used simply by installing the MPEG decoding function.
TRA (Enhanced CD) can be used.
Recently, the number of personal computers equipped with the decryption function as standard is increasing. For this reason, demand for CD-EXTRA (enhanced CD) is expected to increase significantly for personal computers.

[0006] In a device for accessing a DVD, since a CD-ROM device is widely mounted on a personal computer, in addition to a function for accessing a DVD, a CD-ROM (including an enhanced CD) is included. ) Etc. are considered to be installed in personal computers in the form of adding a function that enables reproduction.

[0007]

The above-mentioned CD-EXTRA
And the like, you can enjoy high-quality sound and numerous images, just like music CDs. However, the sound and video are basically performed by reproducing data sequentially read from a CD. In other words, although data of a wide range of expression media such as images (still images, moving images, photographs, etc.) and music can be recorded, such data has not been fully utilized. This is the same for storage media other than the enhanced CD.

[0008] It is an object of the present invention to effectively utilize data stored in a storage medium and reproduce the data in various forms.

[0009]

Means for constituting a storage medium reproducing apparatus of the present invention and a storage medium 1 reproduced by the reproducing apparatus will be described with reference to the principle diagram shown in FIG.

First, the storage medium 1 has a first storage area 1a and a second storage area 1b distinguished by stored data. The distinction based on the data includes, for example, the difference in the data reproduction mode (the difference between audio and video, the expression media (characters, voices, moving images, still images, etc.)
, Etc.) or a difference in data format. The storage medium 1 includes an enhanced C
D (for example, CD-EXTRA), DVD, optical disk,
A magneto-optical disk or the like corresponds.

The first reading means 2 reads the data stored in the second storage area 1b of the storage medium 1 and stores it in another storage medium 3. Other storage media 3 include:
All data in the second storage area 1b may be stored, or only data extracted from the data may be stored. For example, when the playback device is constructed using a personal computer, the main storage device and, in addition, an auxiliary storage device (such as a hard disk device) correspond to another storage medium 3.

The first reading means 2 reads data stored in the first storage area 1 a of the storage medium 1 and outputs the data to the first reproducing means 4. The first reproducing unit 4 reproduces the data received from the first reading unit 2.

[0013] The second reading means 5 includes the other storage medium 3.
Then, the first reading means 2 reads the stored data and outputs it to the second reproducing means 6. Second reproducing means 6
Reproduces the data received from the second reading means 5.

By storing the data stored in the second storage area 1b of the storage medium 1 in another storage medium 3,
Data stored in different storage areas of the first storage area 1a and the second storage area 1b can be reproduced simultaneously (in parallel). In other words, a combination of data of various expression media stored in the storage medium 1,
It is possible to arbitrarily select and control the timing of reproducing those data. As a result, the range of options and usage forms of the user's enjoyment is widened, and the entertainment and the like of the storage medium 1 are improved.

The control means 7 reproduces the data read from the first storage area 1a of the storage medium 1 by the first reading means 2 by the first reproducing means 4 and the second reproducing means 6 The reading means 5 synchronizes (cooperates) with the reproduction of the data (data stored in the second storage area 1b of the storage medium 1) read from the other storage medium 3.

The control means 7 relates these data to each other such that the data reproduced by the first reproducing means 4 is music and the data reproduced by the second reproducing means 6 is an image corresponding to the music. If there is, the data is synchronized and reproduced according to the prepared reproduction management information. The reproduction management information is, for example, information that defines a correspondence relationship between related data for each data reproduction unit (a unit for a phrase for music and one screen for a still image). By using such reproduction management information, it is possible to specify an arbitrary reproduction position (reproduction start time, reproduction end time, etc.) such as in the middle of a song, and reproduce (synchronize) the data at the specified reproduction position in a synchronized manner. Becomes

In FIG. 1, the second storage area 1 of the storage medium 1
b, and prepares the reproduction management information in the second storage area 1b.
By storing it in another storage medium 3 together with the data of
The control means 7 acquires the reproduction management information from another storage medium 3. In this way, it is not necessary to prepare a storage medium for storing the reproduction management information, and the reproduction of data on different storage areas can be synchronized only by preparing the storage medium 1. . That is, it is advantageous in terms of cost, operability, and the like.

The personal computer currently shipped is equipped with all the hardware corresponding to each of the above-mentioned means provided in the reproducing apparatus of the present invention, or is equipped with all the hardware even if not all. It has become easier.
Since many are shipped as multimedia personal computers, the fact is that many of them are equipped with all the functions necessary for constructing the playback apparatus of the present invention on hardware.

Therefore, a program for realizing the operation of the reproducing apparatus of the present invention may be stored in the storage medium 1, and the user may purchase it. When the program is stored in the storage medium 1, the user can construct the reproducing apparatus of the present invention only by purchasing the storage medium 1. This provides advantages in terms of cost, operability, and the like.

FIG. 3 is a conceptual diagram showing a basic operation of data reproduction in the present embodiment. Prior to providing a detailed description of FIG. 2, FIG. 3 and subsequent FIGS.
, CD-EXTRA10 according to the present embodiment
3 and the basic operation of reproducing recorded data will be described.

The CD-EXTRA (storage medium) 103
The program area is divided into two areas, a first session 103a and a second session 103b, according to the format of the recorded data. The first session 103a includes a CD-DA track and the second session 10
3b is provided with a data track. Although not shown, the innermost track (lead-in area) of the video CD 103 has, like the music CD, TOC (table of contents) information indicating the start address of each track and the like. Is recorded.

FIG. 4 is a view for explaining the data structure of the CD-EXTRA 103. As shown in FIG. 4, data (music data) of a CD-DA track is recorded in the first session 103a, and a CD-DA track is recorded in the second session 103b.
-Data is recorded in the same format as ROM. MPEG (audio / video) data can also be recorded in the second session 103b. The sessions are separated by lead-in and lead-out markings. With this marking, the data stored in the first session 103a can be reproduced by a CD player corresponding to only a normal music CD. Hereinafter, the data stored in the first session 103a is referred to as CD-DA data, and the data stored in the second session 103b is referred to as CD-DA data.
-Call it ROM data.

The data recorded on the CD-EXTRA 103 is also managed as a file classified according to a hierarchical structure, similarly to the CD-ROM. PC 101
OS (operating system) installed in the server
When a CD is set in the CD-ROM device 104, a file having a predetermined name (for example, autorun.
It is assumed that a function (auto play function) for checking whether or not inf) is recorded, and for processing the file according to the content described in the file if the file is recorded, is provided.

For this reason, in the second session 103b of the CD-EXTRA 103, a file having a predetermined name that describes the content to be executed by the OS 111 is recorded. The second session 10a is linked (synchronized) with the reproduction of the CD-DA data recorded in the first session 103a.
Viewer software 1 which is application software for reproducing (displaying) the data recorded in 3b
10 is also recorded.

The file includes viewer software 110 and data specified in the second session 103b, for example, information on a disc (album), character data such as song titles and lyrics, and image data (MP
EG encoded data (video and / or audio)
Is loaded (copied) into the main storage device 201 of the personal computer 101 (a part of the storage is also stored in the auxiliary storage device 106 depending on the storage capacity of the main storage device 201 and its use state), and the viewer software 110 is loaded. It describes starting. Therefore, the content of the description is
1 will be realized. The personal computer 10
The data loaded in No. 1 will be referred to as load data 202 to distinguish it from other data.

By loading data recorded in the second session 103b into the personal computer 101, data recorded in different areas of the first session 103a and the second session 103b can be simultaneously processed (reproduced) or can be arbitrarily processed. , And the timing for reproducing them can be arbitrarily controlled. Further, since the viewer software 110 is stored in the CD-EXTRA 103, a user who already has the necessary hardware can realize the sound reproduction / display system according to the present embodiment simply by purchasing the CD-EXTRA 103. be able to. As a result, the economic burden on the user can be reduced.

In this embodiment, the load data 2
02 is performed by the OS 111, but it is determined whether or not the load data is copied to the main storage device 201 so as to be compatible with an OS having no auto play function. In the case where is not copied, the viewer software 110 may have a function of copying it to the main storage device 201. As a result, regardless of whether the auto play function is installed or not,
The load data 202 can be copied to the main storage device 201. That is, operability can be improved.

According to the description of the file, the viewer software 110 is loaded into the main storage device 201, and then, as shown in FIG. After the activation, a moving image, a still image, and a sound are reproduced according to a user's instruction according to a predetermined reproduction procedure. The TOC information recorded in the lead-in area of the CD-EXTRA 103 is stored in the main storage device 201, and is used for confirmation or designation of the reproduction position of the CD-EXTRA 103.

The viewer software 110 receives data (CD-recorded) recorded by the user in the first session 103a.
When the reproduction of the DA data is instructed, the reproduction start position on the first session 103a is determined according to the contents of the instruction, and the reproduction start position is instructed to the CD-ROM device 104, so that the user desires. The reproduction of the CD-DA data is started.

On the other hand, the viewer software 110
Retrieves and obtains related information (data) to be reproduced together with the CD-DA data from the load data 202 in accordance with the content of the user's instruction, and displays it on the screen.

FIG. 5 is a view for explaining the configuration of data loaded into the personal computer 101 from the second session 103b of the CD-EXTRA 103. As shown in FIG. 5, time information (playback management information),
Lyrics, images, additional information, and other data are loaded into the personal computer 101. Among the various kinds of information, the time information is the CD-DA recorded in the first session 103.
This is information for synchronizing (linking) data with data corresponding to (relevant to) it for reproduction.

As is well known, in a music CD, the position of CD-DA data in a track is expressed by MS.
F (M is minutes, S is seconds (00-59), F is frame (0
0 to 74)). CD
Also in the EXTRA 103, since the CD-DA data can be reproduced by a normal music CD player, the time unit is adopted in the first session 103b in which the CD-DA data is recorded. For this reason, the time unit is also used in expressing time information. As the time unit, another unit such as the number of sectors may be adopted.

On the other hand, as a reproduction unit, a reproduction unit in music is used in accordance with the use of MSF for expressing time information. Specifically, a phrase is used as a reproduction unit. As shown in FIG. 5, the playback position of a phrase is managed by its playback start time and its end time for each phrase. Thus, in the present embodiment, the reproduction position in the music can be specified in phrase units.

Data such as lyrics and images to be reproduced in conjunction with the CD-DA data are divided according to the phrases, and their correspondence is defined. The definition of the correspondence is
For example, the time information is converted into an array variable, and in accordance with the conversion into an array variable, the data itself such as lyrics and images, or the storage information (file name and the like) of the corresponding data is converted into an array variable. This makes it possible to manage the reproduction of data to be reproduced in conjunction with the CD-DA data in units of phrases.

The correspondence between the music and the data to be reproduced in conjunction with the music can be specified by preparing a file defining the correspondence between them, for example.

FIG. 6 is a diagram showing an example of the contents stored in the first session 103a of the CD-EXTRA 103.
FIG. 7 is a diagram illustrating an example of extracting data corresponding to one phrase. The correspondence between the data defined as described above will be specifically described with reference to these drawings.

In FIG. 6, 〜 indicates a track number, and tracks on which music data for karaoke are recorded are shaded. Accordingly, FIG. 6A shows the first version in which the original version of the song is recorded in each track of the track number, and the karaoke version of the song recorded in the track of the track number is recorded in the track of the track number. The session 103a is shown. On the other hand, FIG. 6 (b) shows the original version of the song recorded on each track of the track number, and the karaoke version of the song recorded on each track of the track number on each track of the track number. 1 shows the first session 103a that is being performed.

As shown in FIGS. 6A and 6B, the karaoke version is recorded in addition to the original version of the song, because karaoke is widely established in society as one of entertainment. That's why. FIG. 7 shows that when the contents as shown in FIG. 6A or 6B are recorded in the first session 103b, the user designates a track number and a certain phrase in the music recorded on the track By doing so, part of the data (lyrics, translations, and reading character data) extracted from the load data 202 is specifically shown.

In FIG. 7, 〜 indicates time information (see FIG. 5). As shown in FIG. 7, when the same tune having a different performance form is recorded on a plurality of tracks, the time information in each track is linked. This is because the data linked to the reproduction of the CD-DA data is common to the original version and the karaoke version, and the user can select which of the original version and the karaoke version to reproduce. is there.

In the time information (1), ","
And four numbers separated by “:” respectively represent a track number, a minute (M), a second (S), and a frame number (F) from the left as viewed in the figure. Therefore, the performance time of the phrase shown in FIG. 7 is 5 (= 25−20) seconds 26 (= 70−4).
4) It is a frame.

As described above, the correspondence between the data recorded in the first session 103a and the data recorded in the second session 103b is defined by the reproduction unit (phrase in the present embodiment). As a result, reproduction in which those data are synchronized in the reproduction unit and designation of the reproduction position in the reproduction unit are realized.

When the CD-ROM device 104 starts reading CD-DA data and starts reproducing the data, as shown in FIG. 3, the viewer software 110 reads the CD-RO data.
The reproduction information (information indicating the current reproduction position) is sequentially acquired from the data received from the controller 109 of the M device 104, the progress thereof is monitored, and the reproduction information is compared with the time information to thereby display the next data to be displayed. Is specified, and the specified data is obtained from the load data 202 and displayed. As a result, the CD-DA data and the information related to the CD-DA data in the load data 202 are linked (synchronized) and reproduced.

Returning to the description of FIG. CD-ROM device 10
When the CD-EXTRA 103 is set to 4, the controller 109 detects this, for example. Thereafter, the controller 109 causes the read head 108 to seek,
The TOC information recorded in the lead-in area of the CD-EXTRA 103 is read, and when the TOC information is read, the read head 108 is sought toward the outside of the lead-in area, and the CD-ROM device 104 is read from the marking (see FIG. Type of CD set in (Enhanced CD
Or not). For example, the CD-ROM device 104 is connected to the OS 111 via the driver software 112.

t to Fourteen Modulation). The data read from the CD by the read head 108 is passed from the controller 109 to the OS 111 via the driver software 112 after the controller 109 demodulates the data.

The OS 111 is a driver software 11
When the above information is received via the CD-ROM 2, the data recorded on the CD set in the CD-ROM device 104 is read based on the TOC information, the contents recorded on the CD are examined, and the contents of the CD are checked. Specify the type. Thereby,
If it is determined that the CD is not a music CD, C
It is checked whether a file having a predetermined name is recorded in the files recorded in D. As a result, if a file with the predetermined name is recorded, the process is executed according to the contents described in the file. Thereby,
As described above, the viewer software 110 and the specified data 202 in the second session 103b are loaded into the main storage device 201, and the viewer software 1
10 is activated.

When there is not enough free space to store data in the main storage device 201, the OS 111 stores data that cannot be stored in the auxiliary storage device 106 via the driver software 114.

When the viewer software 110 is activated, the TO-total in the lead-in area of the CD-EXTRA 103 is
The C information is stored in the main storage device 201. Thereafter, data is reproduced according to a predetermined data reproduction procedure (PSD). For example, immediately after startup, CD-EX
A description of the contents recorded in the TRA 103 (title, information on the artist (photograph, name, etc.), information on the production company) and the like are written in a still image or a moving image as CR.
After the display at T102, a screen having a predetermined configuration is displayed. Thereafter, the data to be reproduced is specified according to the instruction from the user, and the data to be displayed is displayed in the screen configuration.

The viewer software 110 specifies, from the position where the mouse cursor M was displayed at the time of the click operation, which track of the phrase, the original version or the karaoke version specified by the user is to be reproduced, and
The controller 109 in the D-ROM device 104 is instructed to start reading data.

In this way, the reproduction position and the reproduction content are changed in phrase units according to the instruction from the user. For example, in the example shown in FIG.
The playback position of the phrase is switched from 01 to the lyrics area 901 where the mouse cursor M is displayed, and the playback of the phrase starts in the original version. After the reproduction of the phrase is started, data reproduction is continued according to a predetermined reproduction procedure unless the user gives an instruction. In the present embodiment, the phrase following the phrase is continuously reproduced.

As described above, since the playback position in the song is specified by the lyrics of the phrase displayed in the lyrics area 901, the user can easily specify the playback position, and can perform the operation of changing the playback position. The associated burden on the user is reduced.

FIG. 11 shows a CD-E according to a user operation.
FIG. 3 is a diagram for explaining a flow of reproduction of the XTRA 103. First
Focusing on the reproduction of the data recorded in the session 103a, the user operates the CD-EXTRA 103 after setting the CD-EXTRA 103 in the CD-ROM device 104 and ending the viewer software 110 activated by the setting. In this case, the flow of data that is switched and reproduced in response to the karaoke is extracted (limited to karaoke). With reference to FIG. 11, the operation of the above viewer software 110 will be described.

The user inserts the CD-EXTRA 103 into the CD-
When it is set in the ROM device 104 (S1), the fact is indicated by C
The OS 109 is notified from the controller 109 of the D-ROM device 104 via the driver software 112.

The OS 111 that has received the notification sends a CD
After determining the type of the CD set in the ROM device 104, it is checked whether a file with a predetermined name is recorded on the CD. The user inserts the CD-EXTRA 103 into a CD-R
When set in the OM device 104, the CD-EXTRA1
03 stores a file with a given name,
The OS 111 starts processing according to the description of the file (S2). By executing the process according to the description of the file, the viewer software 110 and the data 202 specified in the second session 103b are copied from the CD-EXTRA 103 to the main storage device 201 (S3). The viewer software 110 is subsequently activated (S4).

The viewer software 110 makes an inquiry to the user as to whether or not it can be started immediately after startup, and starts up when the user permits the startup. If the user does not permit it, the sequence shown in FIG.
It will end with 4.

When the user permits the startup, the viewer software 110 starts reproducing the load data 202 copied on the main storage device 201 and the data recorded in the first session 103a of the CD-EXTRA 103. In the initial stage, for example, CD-EXTRA10
After the display of information on the contents of the first session 10 and the display of the information on the contents stored in the first session 10 are performed, a screen 800 as shown in FIG. 8 is displayed on the CRT 102 and the information area 803 is displayed.
The lyrics of the first song recorded in 3a are displayed (S5). After that, the reproduction of the CD-DA data of the music is started (S6), and the operation shifts to a state of receiving a user operation (S7).

Steps S8 to S29 following step S7
Represents an operation to be performed in accordance with the content of data reproduction desired by the user, and switching of data reproduction by performing the operation.

When the user wants to change the music to be played, the user clicks the title of a desired music among the titles of the music displayed in the select list area 802 (S7 → S8 → S9). Clicking on the song title will cause the viewer software 110 to display the song CD
The main storage device 20 stores the number of the track on which the DA data is recorded and the data to be displayed in synchronization with the reproduction of the song.
1 and the reproduction of the music is started, and the data obtained from the load data 202 is displayed on the CRT 102 (S10, S1).
1). Thereafter, the user waits for an operation while synchronizing the reproduction of the music and the reproduction of the related data (S1).
1 → S7).

The reproduction of the music is performed by the CD-ROM device 10.
After sending the playback start position of the CD-EXTRA 103 to the controller 109 of the No. 4, the CD-DA data received from the controller 109 via the OS 111 and the driver software 112 is sent to the decoding unit 116 via the OS 111 and the driver software 113. Done in The reproduction of the data related to the music is performed, for example, on the CD-D.
The current playback position is obtained from the data of the sub-coding Q channel included in the A data, and the current playback position is compared with the time information to synchronize with the playback of the music.

The user can change the reproduction position in the music,
That is, when the user wants to fast-forward or rewind the music being reproduced, the user clicks the lyrics area 901 in which the desired phrase is displayed in the information area 803 (S7 → S12 → S13). When the lyrics area 901 is clicked, the viewer software 110 refers to the time information and loads the reproduction start position of the phrase displayed in the lyrics area 901 and the relevant data to be reproduced with the phrase on the main storage device 201. The data obtained from the data 202 is started to reproduce the phrase, and the data obtained from the load data 202 is
(S14, S15). For example, characters (highlighted) indicating that the phrase is being reproduced and an image such as a background (including a change in background color) are displayed in the lyrics area 901. After that, while performing the reproduction of the music and the reproduction of the related data in synchronization, the state shifts to a state of waiting for the user's operation (S15 → S
7).

When the user wants to play the original version of the song (including switching from the karaoke version to the original version), the lyrics area 901 displaying the desired phrase is displayed.
Is clicked, avoiding the karaoke button K (S7 → S
16 → S17). When the lyrics area 901 is clicked in such a manner, the viewer software 110 refers to the time information, and stores the reproduction start position of the phrase displayed in the lyrics area 901 and the relevant data to be reproduced by the phrase on the main storage device 201. , The reproduction of the phrase is started, and the data obtained from the load data 202 is displayed on the CRT 102 (S18, S19). After that, while performing the reproduction of the music and the reproduction of the related data in synchronization, the state shifts to a state of waiting for a user operation (S19 → S7).

When the user wants to switch the reproduction of the music from the original version to the karaoke version, the user clicks the karaoke button K in the lyrics area 901 on which the desired phrase is displayed (S7 → S29 → S21). The lyrics area 901
When the karaoke button K is clicked, the viewer software 110 reads the lyrics area 901 from the time information.
The reproduction start position of the phrase displayed in the karaoke version of the phrase (see FIG. 7) and the relevant data to be reproduced in the phrase are obtained from the load data 202 in the main storage device 201, and the reproduction of the karaoke version of the phrase is performed. Is started, and the data obtained from the load data 202 is transferred to the CRT.
It is displayed on the display 102 (S22, S23). After that, while reproducing the music and the reproduction of the related data in synchronization, the operation of the user is waited (S23 → S7).

When the user wants to repeatedly play the designated music, he or she clicks the repeat button displayed in the command area 801 (S7 → S24 → S2).
5). When the repeat button is clicked, the viewer software 110 restarts the reproduction from the beginning of the music after the reproduction of the music is completed, and displays related data on the CRT 102 in accordance with the reproduction (S26, S2).
7). After that, while the reproduction of the music and the reproduction of the related data are performed in synchronization, the operation of the user is waited (S2).
7 → S7).

The repeat button can be clicked to set repeat playback and then clicked again to cancel the repeat playback setting. However, since the cancellation of the setting does not directly affect the operation during the data reproduction, a portion relating to the cancellation of the setting is omitted in FIG.

When the user wants to end the viewer software 110, the user clicks the EXIT button displayed in the command area 801 (S7 → S28).
→ S29). When you click the EXIT button, O
In step S111, the CPU allocation to the viewer software 110 is released, and the viewer software 110 is terminated.

The viewer software 110 loaded in the main storage device 201, the main storage device 201, and the load data 20 stored in the auxiliary storage device 106
2 is then erased by the OS 111. This is because the viewer software 110 is relatively small (C
Reading from the D-EXTRA 103 does not take much time and its recording capacity is small), and the load data 202 includes the audio data (CD-D
CD-EXTR to link playback of A data)
A103 must be set in the CD-ROM device 104 and can be read from the CD-EXTRA103 at any time. By doing so, it is possible to avoid unnecessary reduction in the use efficiency of the auxiliary storage device 106. However, at present, since the capacity of the auxiliary storage device 106 is increasing, the viewer software 110 read from the CD-EXTRA 103 and the load data 2
02 may be held in the auxiliary storage device 106 as needed.

FIG. 12 is a diagram showing details of step S2 in FIG. This means that, as described above,
-This is a process executed by the OS 111 by setting some CD in the ROM device 104.

When the user sets a CD in the CD-ROM device 104, the controller 109 in the CD-ROM device 104 detects this and determines the type of the CD. From the controller 109 to the OS 111, for example, C
When CD is set in D-ROM device 104, TO
C information and the type of the CD (whether or not it is an enhanced CD) are notified. FIG. 12 shows the flow of the processing operation after receiving these notifications. The processing will be described in detail with reference to FIG.

Incidentally, whether or not an enhanced CD is identified
The controller 109 causes the read head 108 to seek over the entire area of the CD, and performs this operation based on whether or not a marking indicating a section break is formed on the CD.

First, in step S31, the CD-ROM drive 10 is controlled based on the information sent from the controller 109.
It is determined whether the CD set to 4 is an enhanced CD, that is, whether there is the second session 103b.

If it is determined that there is the second session 103b, the process proceeds to step S32, where the contents (data format) recorded in the second session 103b are stored.
Find out. As is well known, the format of the data recorded in the divided areas differs depending on the type of the enhanced CD. Therefore, by examining the contents, the type of the enhanced CD can be specified.
Whether the data is CD-ROM data or CD-DA data can be determined from the Q channel data of the subcoding or the contents of the sector header.

In step 33 following step 32, C
It is determined whether or not a file having a predetermined name is recorded in D. The predetermined name is, for example, Autorun. Inf, if a file with that name has been recorded, the process proceeds to execution of processing according to the content described therein (S3).
3: YES). That is, in FIG. 11, the process proceeds from step S2 to S3. If not, the process related to the CD is ended there (S33: NO).

On the other hand, in the step S31, the second session 1
If there is no 03a, that is, if NO is determined, step S3
Move to 4. In step S34, the data recorded there is read from the track having the track number 1, and its format is checked. The reading of the data
This is realized by the OS 111 transmitting the data of the head position of the track obtained from the TOC information to the controller 109 in the CD-ROM device 104 as a control command.

In step S35 following step S34, the data sent from the controller 109 is stored in the CD-D.
It is determined whether the data is A data. If CD-DA data is recorded on the track, the determination is YES, and the process shifts to a process of starting reproduction (playing) as a music CD. If not (for example, if the CD is a CD-R
If it is OM), the process proceeds to step 32 to check whether a file having a predetermined name is recorded, and to execute the subsequent processing according to the result. FIG.
9 is a flowchart showing a reproduction position change process executed by the viewer software 110 when the user clicks a lyrics area 901 including a karaoke button K. FIG.
In the flowchart shown in FIG. 1, steps S14 → S15,
Steps S18 → S19 and steps S22 → S23
Is realized by executing the reproduction position changing process.

After starting the reproduction of the music, the viewer software 110 is in a state of waiting for an event that the user clicks the screen 800 of the CRT 102 while performing necessary processing. When the user performs the click operation in that state, the driver software 11
5 and information on the click operation position of the mouse 105 (display position information of the mouse cursor M) via the OS 111 (S41). When the display position information is obtained, the next time from the display position information,
It is determined whether or not the mouse cursor M is displayed in the lyrics area 901 (S42).

If it is determined in step S42 that the display position of the mouse cursor M at the time of the click operation is not within the lyrics area 901 (S42: NO), step S41 is performed.
It returns to the process of and waits for a new click operation to be performed. Conversely, if it is determined that the display position is within the lyrics area 901 (S42: YES), then it is determined whether the display position is within the lyrics area 901 during performance (during playback) (S43). If it is determined that the display position is within the lyrics area 901 being played (S43: YES), step S4 is performed.
It returns to the process of 1.

On the other hand, if it is determined in step S43 that the display position of the mouse cursor M at the time of the click operation is not within the lyrics area 901 being played (S43, NO),
Next, a lyrics area 901 corresponding to the phrase currently being played.
Is displayed normally (S44). Subsequently, the lyrics area 901 specified by the user by the click operation is highlighted (S45).

As a result, the screen 800 of the CRT 102 is displayed.
(Information area 803) is shown in FIG.
9 changes as shown in FIG. 9B. That is, the lyrics area 901 where the user has clicked is highlighted, and the lyrics area 901 is changed to the normal display.

When the lyrics area 901 specified by the user is highlighted, it is then determined whether the currently set mode, that is, the specified reproduction is the karaoke version or the original version (S46). The data necessary for reproducing the music is acquired from the load data 202 according to the determined mode.
The playback start time of the phrase in the designated lyrics area 901 is acquired here.

Subsequently, based on the obtained data, the OS
The controller 109 instructs the controller 109 via the 111 and the driver software 112 to read the data, and displays the data acquired in step S47 on the screen 800 of the CRT 102. After that, the processing shifts to a standby state waiting for a user's click operation.

In this way, the viewer software 1
Numeral 10 synchronizes (cooperates) the reproduction of the data recorded in the second session 103b with the reproduction of the CD-EXTRA 103 as a music CD, that is, the reproduction of the CD-DA data recorded in the first session 103a. this is,
The same applies to the case where a song is reproduced from the beginning.

In the present embodiment, the lyrics are displayed in units of phrases, and the playback position is changed by specifying the phrase. For example, the playback position is specified by specifying the playback elapsed time from the beginning of the song. May be changed. Alternatively, for example, a number may be assigned to each of the play positions that can be changed in advance, and the play position may be changed according to the designated number. In addition, an arbitrary reproduction position in each music piece may be similarly specified for a plurality of music pieces as well as in one music piece.

For the specification of the playback content of the karaoke version or the original version, for example, as shown in FIG. 9, a plurality of lyric areas 901 are displayed on the CRT 102, and each lyric area (phrase) 901 is displayed. May be specified by the user.

In any of the above cases, the CD-EX
By reproducing the related data recorded in different areas of the TRA 103 in conjunction with each other, the data recorded therein can be used more effectively, thereby providing a wider data reproduction mode to the user. it can. Therefore, the CD-EXTRA 103 can be provided as a product that is more comfortable for the user and highly entertaining.

Next, another reproduction example of the CD-EXTRA 103 and viewer software 1 for realizing it.
The operation of No. 10 will be described. The above-described reproduction example is based on reproducing character data such as lyrics thereof in synchronization with reproduction of music (CD-DA data). On the other hand, in another reproduction example, a still image is reproduced in addition to the reproduction of character data. This will be described with reference to FIGS.

FIGS. 14 and 15 are diagrams showing another example of reproduction of CD-EXTRA. These are the first session 1
This is an example of a case where an image and characters corresponding to the music in the load data 202 are displayed in synchronization with the reproduction of the CD-DA data recorded on the CD-DA 03a.

In the reproduction example shown in FIG. 14, the music is reproduced by reproducing the CD-DA data of the first session 103a, synchronized (linked) with the music, and the still images and characters related to the music are loaded into the load data. The information is acquired from 202 and displayed. Still images are tailored to the story of the song. For this reason, the user can enjoy karaoke while enjoying the atmosphere of the music with the still image.

In the reproduction example shown in FIG. 15, the reproduction of the still image and the text in conjunction with the reproduction of the sound is not shown in FIG.
4 is the same as the reproduction example shown in FIG. 4, except that the characters to be displayed are in a language different from the language of the sound to be pronounced. Specifically, this is an example in which the reproduced sound is in English, but Japanese (Japanese translation) is displayed.

When such reproduction is performed, learning that appeals to the audio-visual sense can be performed for the user, and a high learning effect can be obtained. As shown in FIG. 15, when scenes (still images) representing the reproduced audio contents (story) are sequentially displayed, the visual information is added to the correspondence between English and Japanese. Therefore, English can be more easily remembered, and a high learning efficiency of a foreign language can be obtained. Thus, the CD-EXTRA 103 can be provided as a teaching material that enables effective foreign language learning.

The characters to be displayed may be read in another language in addition to the translation of the language to be pronounced, and may be in that language. The user may be allowed to select the type of characters to be displayed.

Next, the operation of the viewer software 110 for synchronizing (linking) the reproduction of the data related to the load data 202 with the reproduction of the sound (the data of the first session 103a) as described above, with reference to FIG. Will be explained. FIG. 16 is a flowchart of the related data reproducing process. Here, in order to avoid confusion, the CD-DA data of the first session 103a will be described as music data.

In the related data reproducing process, first, a music number currently being reproduced (start of reproduction is instructed) is obtained (S51). Next, load data 2 of the main storage device 201
From 02, character data (lyrics, translation, pronunciation (reading)) and image (still image) data related to the acquired song number are acquired (S52).

When the related data is acquired, the data is then combined with the currently reproduced music piece by one.
The image is displayed only for the screen (S53). By executing step S53, the display of the still image or the lyrics is switched. Next, the current playback location of the CD-EXTRA 103,
For example, the time elapsed since the start of the reproduction of the music having the music number (reproduction elapsed time) is obtained as reproduction information (S5).
4). The elapsed playback time is the playback position of the song being played, which the controller 109 of the CD-ROM device 104 sends to the viewer software 110, that is, the performance position. The playing position is data indicating how many minutes, seconds, and frames are being reproduced from the beginning of the music. When such playback information (playback location) is obtained, the state of the display location is changed, such as highlighting the character corresponding to the playback information (S55).

When the character highlighting is changed in real time during the reproduction of the music in this way, it is determined whether or not the performance of one music has ended (S56). This determination is made, for example, by comparing the performance time of the music obtained from the TOC information with the performance elapsed time obtained in step S54 described above.

If it is determined in step S56 that the performance of the music has ended (S56: YES), the process ends. On the other hand, if it is determined that the reproduction of the music has not been completed (S56: NO), the process proceeds to step S57.

In this embodiment, every time the reproduction of one phrase is completed, all the images (still images and lyrics) displayed on one screen 800 (information area 803) are changed (redisplayed). I have. For this reason, in step S57, it is determined whether or not the image needs to be redisplayed based on whether or not the reproduction of one phrase has been completed. This determination is made, for example, by comparing the playback end time of the phrase in the time information with the playback elapsed time indicating the playback location acquired in step S54.

If it is determined in step S57 that the performance of one phrase has not been completed (S57: NO), it is determined that there is no need to redisplay the image, and the process returns to step S54. Conversely, if it is determined that the performance of one phrase has been completed (S57: YES), it is determined that the image needs to be redisplayed, and the process returns to step S53. Step S53
By the execution of the above processing, another still image and character are newly displayed in the information area 803.

In this way, the viewer software 1
10 is the first session 10 of the CD-EXTRA 103
3b is loaded with the load data 2
02, that is, a plurality of data (still images and characters) having different expression media recorded in the second session 103b are synchronized (linked). This allows
Data reproduction as shown in FIGS. 14 and 15 can be realized.

The other reproduction example described above is based on the first session 10
The reproduction of the display data such as still images and characters is synchronized (linked) with the reproduction of the CD-DA data recorded in 3a. However, the second of CD-EXTRA103
The session 103b includes audio output data (MPE
G data or MIDI data) can also be recorded.
The reproduction example shown in FIG. 17 is an example in which the reproduction of the audio output data in the load data 202 is synchronized (linked) with the reproduction of the CD-DA data.

As shown in FIG. 17, in this reproduction example, the phrase to be reproduced next to the phrase currently being reproduced is stored in the data in the load data 202, that is, the second session 103.
By reproducing the data recorded in b, sound is output. This is for example, in order to assist a visually impaired person in singing by informing in advance the next phrase to be sung. This allows more people to use CD-EXTR
A103 can be provided in a more useful form. Note that the next phrase to be sung is separated by an earphone, while the audio output by reproducing the CD-DA data is a speaker so that the phrase to be sung next is inaudible by reproducing the CD-DA data. It is desirable to output on the channel of.

As described above, the correspondence between the CD-DA data and the data related thereto is defined for each phrase. Therefore, the reproduction as shown in FIG.
This can be realized by shifting the correspondence one phrase earlier and reproducing the related data in the load data 202. In other words, it can be realized by executing exactly the same processing as the flowchart shown in FIG. Therefore, the processing executed by the viewer software 110 to realize the reproduction example shown in FIG. 17 is omitted.

Although the characters of the phrase are not displayed in the reproduction example shown in FIG. 17, the characters may be displayed together with the voice. Such reproduction may be performed not only for music but also for learning a foreign language.

Conventionally, when it is desired to simultaneously reproduce an image and a sound, the data is compressed and recorded by the MPEG encoding method or the like. However, like this, CD-EX
By loading the data recorded in the second session 103b of the TRA 103 onto the personal computer 101, it is possible to reproduce the loaded data 202 and the data recorded in the first session 103a in various combinations. For this reason, even if each image and sound data is recorded in a separate recording area, the image and the sound can be reproduced simultaneously. This means that the restriction according to the content to be reproduced of the data stored in the storage medium can be reduced. Thus, data to be stored in the storage medium can be selected according to the purpose. In the present embodiment, by reproducing the CD-DA data (uncompressed data) recorded in the first session 103a in accordance with the display of the image, a high-quality sound is always obtained. ing.

In the present embodiment, the CD-DA
The data to be reproduced along with the data reproduction is stored on the CD-
The user arbitrarily selects from the related data of the DA data. However, for example, a mode in which artist information and song information are displayed mainly (artist / song information mode), a mode in which lyrics, translations, and readings are displayed mainly (lyric display mode), and a mode in which discography is displayed mainly (diskography mode) And the basic configuration (arrangement) of data to be displayed in the information area 803 may be determined in advance for each mode. FIG. 18 shows an example of a screen 800 for each mode. The screen 800a is in the artist / song information mode, the screen 800b is in the lyrics display mode, and the screen 800c is in the discography mode.

Next, another embodiment will be described.
In the above embodiment, the data recorded in the second session 103b is reproduced together with the CD-DA data recorded in the first session 103a. On the other hand, in another embodiment, the second session 1
The data which is synchronized (linked) with the reproduction of the CD-DA data can be added by the user to the data recorded in 03b.

FIG. 19 is a block diagram of a schematic configuration of a sound reproduction / display system according to another embodiment. This FIG.
In the above, the same reference numerals are given to components which are the same as those in the above embodiment or have no significant difference. CRT
102 is omitted. Another embodiment will be described with reference to FIG.

In this other embodiment, the sound inputted by the user from microphone 1901 in time with the music is supplied to converter 19.
02 is converted into digital audio data by an A / D converter 1902a, and the viewer software 110
