[0018]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a schematic configuration of a computer as an information reproducing apparatus having a CD (compact disk) automatic starting function and an automatic calling function of related information according to an embodiment of the present invention.

In FIG. 1, a computer 1 has an automatic start program for automatically starting a set CD reproduction program, a selection information determination program for determining a CD Extra priority reproduction program, and related information. A plurality of programs such as a control unit 2 having at least an automatic call program, a reproduction program 3 for CD audio, a reproduction program 4 for photo CD, and a reproduction program 5 for video CD are already prepared.

Further, selection information to be described later and CD-
It has a RAM 6 for loading and holding a reproduction program of the ROM from the CD-ROM, and a reading unit 7 for reading information from the set CD 8. The reading unit includes a hardware device such as a pickup and a driver for driving the hardware device. Further, it has an input unit 9 for inputting and displaying various information, a display unit 10, and a database 18 for searching. The respective units can communicate with each other via a bus line 11, and can communicate with external information servers 13, 14, 15, and 18 via a communication path 12. The above is computer 1
It is a schematic configuration of.

Next, the automatic start function of the reproduction program will be described in detail below. Such a function is mainly implemented by the automatic start program of the control unit 2, and its flowchart is shown in FIG.

When the CD is set in the computer 1,
First, the reading unit 7 is instructed to drive the set CD and read the information (TOC information) of the lead-in area of the first session (the innermost session). Reading unit 7
In response to this command, the driver controls the pickup, motor, etc., reads the information in the lead-in area, and outputs it.

Next, in step 2, information relating to control bits, address bits, minutes, seconds, and frame numbers in the TOC information is obtained. From the control bits, it is possible to identify whether the session is CD audio or CD-ROM. Also, from the address bits, it is possible to identify whether the CD is a single session (that is, only the first session) or a multi-session such as a CD extra.

In step 3, the value of the address bit is confirmed, and it is determined whether the set CD is a multisession or a single session. If it is determined in step 3 that the set CD is a multi-session, the leading time of the next session can be obtained from the TOC information read in step 2, so that the lead-in area of the second session is reproduced. (Step 4). Thereafter, steps 1, 2, and 3, which are performed until the final session, are executed.

After the information of each session is obtained, the type of the set CD is determined by using the information in step 5 and subsequent steps.

In step 5, it is determined from the read control bits of the first session whether the first session is a CD audio or a CD-ROM. When the first session is identified as the CD audio in step 5, the set CD is the CD audio or the CD extra.

In step 6, it is determined whether the CD set from the read address bits of the first session is a single session or a multi-session. In the case of a single session, the set CD is a CD audio, and in the case of a multisession, the set CD is a CD extra. Therefore, the start of the corresponding reproduction program is instructed in steps 7 and 8.

In the CD audio reproducing program, a tune designated in advance (for example, the first tune) is reproduced. Also,
In the reproduction of the CD extra, a reproduction program of either the audio session or the data session is started, which will be described later.

On the other hand, in step 5, the first session
If it is identified as a ROM, proceed to step 9;
As in step 6, whether the CD set from the address bits of the first session is a single session or a multi-session is identified.

If the set CD is a multi-session, there is a possibility of a photo CD, so the LSN 16 (physical address 00: 0) of the last session is determined in step 10.
2:16) VTOC (Volume Table)
of Contents) is instructed to the reading unit, and a directory name under the root directory is obtained (step 12).

If the set CD is a single session, there is a possibility that the CD is a video CD. Therefore, in step 11, similarly, the reading of the VTOC of the first session is instructed to the reading unit (step 11), and the route is set. Get the directory name under the directory (step 1
2).

When the reading of the VTOC is completed, it is determined whether or not a specific directory name is included in the obtained directory names (step 13). Specifically, a PVD (Primary Volume De) constituting the VTOC is used.
(script: basic volume descriptor) has a pointer of the root directory, so that the root directory information is obtained based on this information, and PHOT
A search is made as to whether there is a directory with a name such as OCD or VCD.

That is, when the multi-session is identified in step 9, it is further searched for a directory name of PHOTOCD, and it is determined whether the set CD is a photo CD or another CD-ROM. If it is determined in step 9 that the session is a single session, it is further searched for a directory name of VCD, and it is determined whether the set CD is a video CD or another CD-ROM.

As a result, the set CD is a video CD.
When it is determined that the set CD is a photo CD, the start of a corresponding video CD reproduction program is instructed in step 14. When the set CD is identified as a photo CD, the corresponding photo CD is reproduced in step 15. When the start of the program is instructed and another CD is identified, the playback program is read from the set CD-ROM into the R-ROM.
It is loaded into the AM 6 and activated (step 16).
At this time, if there are multiple executable programs,
Any one of the programs is activated as a reproduction program according to a user's selection or a predetermined priority. The above is the details of the automatic start program. The addition of the above functions further improves the usability.

Next, the activation of the CD extra reproduction program in step 8 will be described below. CD Extras can be played on ordinary music players and
The audio track is arranged in the first session and the data track is arranged in the second session so that it can be used in the ROM drive. Conventionally, when the CD-ROM drive recognizes that the disc is a multi-session disc, it reads the disc from the last session (that is, the data track). Since the CD player for music cannot recognize the existence of the multi-session, the From the session (ie, audio track).

However, like the computer of the present invention,
When both the music CD and the CD-ROM can be reproduced, it is more convenient that the user can determine which session is to be reproduced.

Therefore, in activating the CD extra according to the present invention (step 8 in FIG. 2), steps S31 and S32 for determining a reproduction session are added as shown in FIG. Hereinafter, FIG. 3 will be described.

If it is determined in step 6 of FIG. 2 that the session is a multi-session (ie, CD extra),
At step 31, the stored selection information is read. This selection information is information indicating which session of the CD extra is to be preferentially reproduced, and is held in the RAM 6. For example, when the selection information is 1, it can be defined to indicate priority reproduction of a music session, and when the selection information is 0, it can be defined to indicate priority reproduction of a data session.

In step 32, this selection information is identified,
It is determined whether to give priority to the audio session or the data session. On the basis of this determination result, if the audio session is to be prioritized, a command to start the CD audio reproduction program in step 7 is issued.
Load it into the AM and start it (step 16). By adding the above functions, the reproduction of the CD extra becomes more convenient.

Next, the process of determining the selection information read in FIG. 3 will be described. FIG. 4 is a flowchart showing the selection information determination process. The program is included in the control unit 2 and is executed periodically. First, in step 41, it is determined whether or not a selection request (for example, clicking a selection request key on a display screen) has been made. If there is no request, this process ends. If there is a request, the display unit 10 is instructed to perform a display indicating that the selection mode has been entered (step 42).

Subsequently, it is determined in step 43 whether or not there is an input as to which session has priority. If there is no input of which session has priority, this processing is continued unless there is an input of mode release from the user (step 44: No). If there is an input as to which session is to be prioritized in step 43 (step 43: Yes), in step 45 the RAM
Then, the selection information held in No. 6 is updated based on the input, and the selection information determination processing is terminated. The above is the selection information determination processing. By adding such a function, the user can freely determine which session of the CD extra is to be preferentially reproduced.

In the above-described embodiment, the process of selecting a reproduction session has been described using a CD extra as an example. However, the present invention is not limited to this. Nor.

Next, a function of automatically calling related information will be described. Such a function is mainly implemented by a program for automatically calling related information of the control unit 2, and its flowchart is shown in FIG. Note that such a program can be started in parallel with the CD automatic start program shown in FIG.

First, at step 51, it is detected whether or not a disc has been set. More specifically, when the disk 8 is loaded on the CD tray of the reading unit 7, a detection signal indicating the setting of a CD can be detected from the reading unit 7, so that the detection signal is periodically checked. It is detected whether or not a disc has been set.

If the disc has not been set, the current processing ends. On the other hand, when the set of the disc is detected, the identification information of the set disc is obtained in step 52.

Here, a case will be described in which information indicating the contents of a disc, such as information in the TOC section and CD audio, is used as identification information. The information of at least the TOC part is C
This is necessary for identifying D, and data of minutes, seconds, and frame numbers is used in this embodiment. In addition, although information indicating the contents of the disc is not always necessary, the information is acquired in the present embodiment in order to quickly perform a search process described later. For the specific method of disc content identification, see the automatic start function of the playback program (flow chart in FIG. 2).
Since it has been described in detail at this point, the description is omitted here.

Next, in step 53, a search for keyword information corresponding to the identification information is performed. Specifically, by searching data in a search table held in the database 18, corresponding keyword information (for example, artist name and title name in the case of music CD keyword information) is searched. FIG. 6 shows a configuration example of the search table.
Here, a table is configured for each disc content, and only the data of the corresponding table is set as a search target, thereby reducing the search amount. Further, the identification information and the keyword information need not necessarily correspond one-to-one, and one identification information (for example, identification information 1) may correspond to a plurality of pieces of keyword information (for example, keywords 1 and 2). Conversely, when a plurality of pieces of identification information (for example,
One keyword information (for example, keyword 3) may be associated with the keyword information.

Such a database can be created by user input, or can be obtained from another playback medium (for example, a disk storing the database). Also, the set reproduction medium itself can further store the keyword information. For example, the CD text, which is character information stored in the subcode, can be used as it is as keyword information. In this case, the search processing of the keyword information in step 53 becomes unnecessary.
Further, by accessing another information server 13 having a search unit 16 for searching the keyword information from the identification information and sequentially storing the obtained keyword information in association with the identification information, the database as shown in FIG. May be built.

If the keyword information is obtained by the search (step 54: YES), the address information is searched in step 55. This address information can be, for example, the address of a homepage used on the Internet. FIG. 7 shows a configuration example of the search table at this time.
Shown in In FIG. 7, similarly to FIG. 6, the keyword information and the address information do not necessarily have to correspond one-to-one, and one keyword information (for example, keyword 1) is made to correspond to a plurality of address information (for example, addresses 1, 2). And a plurality of pieces of keyword information (for example, keyword 2,
3) may correspond to one piece of address information (for example, address 3).

Such a database can be created by a user's input, or can be obtained from another reproduction medium (for example, a disk storing the database). Further, the set reproduction medium itself can further store the address information. In this case, the search processing of the keyword information and the address information becomes unnecessary. further,
A database as shown in FIG. 7 is constructed by accessing another information server 15 having a retrieval unit 17 for retrieving address information from identification information and sequentially storing the obtained address information in association with the keyword information. You may.

When the corresponding address information is obtained (step 56: YES), the relevant information of the corresponding address information is obtained and displayed (step 61). Related information such as a homepage can be obtained by accessing the information server 14 of the searched address information via the communication path 12. Also, without using a network, a reproduction medium storing related information (for example, a CD-R storing related information)
OM), it is also possible to acquire the related information of the corresponding address information.

As the related information, for example, a music CD
, The title of the CD, a list of song names, images used on the jacket, lyrics, singer's homepage,
Information such as the name of a singer, the name of a lyricist, the name of a composer, and the name of a performer, etc., are appropriate.

If the corresponding address information cannot be obtained (step 56: NO), the related information cannot be displayed as it is, so that the display unit 10 is controlled so as to request the user for additional keyword information (step 5).
7). FIG. 8 shows an example. Then, the process returns to step 55 based on the additional keyword information input via the input unit 9 to search for the address information. When there is a cancellation command from the user, the display of the related information is stopped.

On the other hand, when the corresponding keyword information cannot be obtained in the search for the keyword information in step 53 (step 54: NO), the database has a larger database than the database of the computer 1, The external information server 13 having the search unit 16 for searching for information is accessed and the identification information is transmitted (step 59). The external information server 13 performs a search and transmits the corresponding keyword information to the computer 1.

If the corresponding keyword information has been obtained (step 60: YES), the corresponding address information is searched in step 55. If the corresponding keyword information is not acquired (step 60: NO), a display requesting the user for additional keyword information is performed (step 57).

The above is the automatic calling process of the related information. By adding such a function, it is possible to automatically display the related information.

In the above embodiment, the search for the address information is performed using the database in the computer 1, but the database in the computer 1 is not always necessary.
For example, the search of the address information in step 56 is performed by searching the keyword information for the corresponding address information.
It can also be performed by another information server 15 having. In this case, the computer 1 transmits the keyword information to another information server 15 and requests a search.

As in steps 53, 54, and 59, a search is performed using the database in the computer 1, and if address information cannot be obtained, a request is made to another information server 15 having a search unit 17 for the search. It is also possible to obtain corresponding keyword information.

Further, it is also possible to search for the keyword information only by the other information server 13 having the search unit 16 for searching the corresponding keyword information from the identification information without using the database 18 in the computer 1. ,
All searches can be performed by other information servers 13 and 15 having search units 16 and 17. In the former case, the computer 1 transmits the identification information to another information server 13 to request a search, and in the latter case, the computer 1
Transmits the keyword information to another information server 15 and requests a search.

In the present embodiment, the keyword information is searched from the identification information, and the address information is searched from the keyword information.
This is to make it easy to use 15 general search functions. Therefore, if another information server having a search unit for directly searching for address information from identification information in addition to a general search becomes general, it is possible to directly search for address information without searching for keyword information. It is. This embodiment is shown in FIG.

This function is mainly implemented by a program for automatically calling related information of the control unit 2. Such a program can also be started in parallel with the CD automatic start program shown in FIG.

First, at step 91, it is detected whether or not a disc has been set. This point is referred to as step 51
Is the same as

If the disc has not been set, the current processing is terminated. On the other hand, if a set of disks is detected, identification information of the set disk is obtained in step 92. This is also the same as step 52.

Next, in step 93, search for address information corresponding to the identification information is performed. Specifically, by searching data in a search table held in the database 18, corresponding address information (for example, in the case of music CD identification information, the address of the singer's homepage) is searched. FIG. 10 shows a configuration example of the search table. Here, a table is configured for each disc content, and only the data of the corresponding table is set as a search target, thereby reducing the search amount. Further, the identification information and the address information do not necessarily have to correspond one-to-one, and one identification information (for example, identification information 1) may correspond to a plurality of address information (for example, addresses 1 and 2). Conversely, a plurality of pieces of identification information (for example, identification information 2 and 3) may correspond to one piece of address information (for example, address 3).

Such a database can be created by a user's input, or can be obtained from another reproduction medium (for example, a disk storing the database). Further, the set reproduction medium itself can further store the address information. In this case, the search for the address information in step 93 becomes unnecessary. Further, a database as shown in FIG. 10 may be constructed by accessing another information server 18 having a search unit 19 for searching for address information from identification information and sequentially storing the obtained address information.

If the address information is obtained by the search (step 94: YES), the relevant information of the corresponding address information is obtained and displayed (step 99). The related information such as the homepage activates a browser program which is a part of the display program, accesses the information server 14 of the searched address information via the communication path 12, and displays the obtained information on the display unit 10. By reconfiguring the display so that it can be displayed, the display on the display unit 10 is enabled. Also, without using a network, it is also possible to acquire related information on the searched address information from a reproduction medium storing the related information (for example, a CD-ROM storing the related information).

If the corresponding address information cannot be obtained (step 94: NO), the related information cannot be displayed as it is, so that a database larger than the database of the computer 1 is provided, and the address information is searched from the identification information. The identification information is transmitted to the external information server 18 having the search unit 19 (step 95). The external information server 18 performs a search and transmits corresponding address information to the computer 1.

If the corresponding address information has been obtained (step 96: YES), the corresponding relevant information is displayed in step 99. If the corresponding address information is not obtained (step 96: NO), the display unit 10 is controlled to display a message requesting the user for additional keyword information or address information (step 97).

When the keyword information is input through the input section 9, the process returns to step 93 to search for the address information. When the address information is input through the input unit 9, the related information is displayed in step 99.

The above is the automatic calling process of the related information. By adding such a function, the related information can be automatically displayed. In the present embodiment, the computer 1 searches for the address information. However, it is also possible to use only the external information server 18 having a search function.

Although the present invention has been described by taking a CD as an example, the present invention is not limited to this.
Other playback media such as.

[0072]

According to the present invention, it is possible to automatically obtain the relevant information relating to the reproduction medium only by setting the reproduction medium, so that the operability can be improved. Also,
Since related information such as a huge number of homepages used on the Internet is accessed on the information server based on the address information obtained from the keyword information, it can be easily obtained.
