[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a DVD player which is one embodiment of a moving image reproducing apparatus having an Internet connection function according to the present invention.

In FIG. 1, the DVD player includes a DVD drive 1 for driving a DVD title 1a as a recording medium and a storage medium such as a CD-ROM in which other programs are stored, a stream reproduction control unit 2, a reproduction control It has an information storage unit 3, a display 5 as display means, a web page table 6, a web page display determination unit 7, a web page display unit 8, a web icon display unit 10, and the like. The display 5 may be an external connection device for the DVD player.

The DVD title 1a is a DVD title disk having a multi-stream section, and has a parental lock. By setting the DVD title 1a, the DVD drive 1 reads the reproduction control information and the stream recorded in the DVD title 1a. The playback control information storage unit 3 stores the read playback control information. The web page display unit 8 is connected to the Internet website group 9 via the communication line 4. The stream reproduction control unit 2 converts the stream read by the DVD drive 1 into image data or the like according to the reproduction control information in the reproduction control information storage unit 3 and displays the data on the display 5. Also, the stream reproduction control unit 2
Refers to the web page table 6 having the position in the stream as a key, determines whether or not the position of the stream being reproduced matches the key, and if they match, the web page display determination unit 7 Notify position in stream. The web page display determination unit 7 compares the playback control information in the playback control information storage unit 3 with the web page table 6, determines whether or not the web page can be displayed, and notifies the web page display unit 8. When the web page display unit 8 receives a notification that the web page can be displayed from the web page display determination unit 7, the web page display unit 8 accesses a web page specified in the web page table 6 to an Internet website according to a procedure determined by the system. To display on the display 5. In the web page table 6, a list in which addresses of web pages are recorded is registered.

The DVD title 1a and the Internet website group 9 are collectively called a predetermined storage medium. The Internet website group 9 includes not only commercial websites but also websites of public institutions, for example. In a website of a public organization, a parental lock is provided for each website in the Internet website group 9 by preparing a multi-scene section including a plurality of scenes in the stream of the DVD title 1a. A scene to be played is selected in advance from the scenes of the multi-scene section, and a method of generating a plurality of titles having different scenes from basically the same title scene according to the selected contents is one of the methods for protecting minors. From the viewpoint, a section that you do not want to show to children such as sexual scenes and violence scenes is set as a multi-scene section in advance,
A function in which a regulation level is set for each section, and usually, only scenes for minors are reproduced.

This DVD player is provided with a parental lock function having eight levels of regulation.

Here, the DVD title 1a is a video title to which a parental lock is applied, and the address list of the web page related to each scene in the video title is outside the DVD video title 1a, for example, in the DVD player. Let us consider the operation when the data is recorded in a memory such as a ROM or a RAM.

In the DVD title 1a with the parental lock, since the level of the parental lock recorded in the DVD title 1a is read by the DVD player as the reproduction control information, the DVD title is being reproduced by the DVD player. In the multi-stream section, a stream that matches the parental level is selected and reproduced. The stream is information of a unit to be reproduced, and is one of a plurality of pieces of video information, audio information, other character information, and the like. The multi-stream section is, for example, a section in which a story branches and another story develops therefrom. Here, a basic operation for displaying a video image will be described. The DVD title 1a to which the parental lock is applied has one or more multistream sections, and the parental level such as an adult stream (parental level 8) and a general stream (parental level 1) is different in the multistream section. Has multiple streams.

The stream reproduction control unit 2 controls the DVD drive 1 to read a stream from the DVD title 1a. The reproduction control information storage unit 3 stores a parental level set by the user in advance. The stream reproduction control unit 2 selects a stream to be reproduced according to the parental level of the reproduction control information storage unit 3 set by the user for the stream in the multi-stream section read from the DVD drive 1.

The stream selected by the stream reproduction controller 2 is reproduced by the DVD drive 1 and displayed on the display 5.

Next, the web page table 6 will be described. The web page table 6 stores a list for displaying web pages. This list is on DVD
This is a dedicated list created for each video title. Here, a storage medium different from the DVD title 1a, for example, R
It is assumed that the information is recorded in a memory such as an OM or a RAM. Note that this list may be stored in the DVD title 1a in which the DVD video title is stored.

As one of the lists, as shown in FIG.
There is a correspondence table 21 of parental lock levels and web page groups.

In the correspondence table 21, a group of web pages is indicated by three parameters of G, R, and X, and is divided here. G is a public group, X is an adult group, and R is a restricted group at an intermediate level. There are eight levels of parental locks for DVD, from level 1 to level 8, which are determined from the viewpoint of protection of minors such as violence, language, and sexual expression.

Level 1 is for the general public and level 8 is for the adult. Regulations become looser toward higher levels. A stream specified at a level higher than the restriction level selected and set by the user is not reproduced. It is assumed that the web page groups correspond to level 1 and group G, level 6 and group R, and level 8 and group X, respectively. Note that the parental lock level and the number of web page groups may be the same, or one of them may be larger as in this example.

As another list, there is a correspondence table 22 as shown in FIG. This correspondence table 22
Has three items: a position in the DVD video title, a web page address, and a group. It should be noted that the present invention does not specify the data structure itself that links the address of the web page and the group set therein, but merely shows an example as a realizing unit.

In the correspondence table 22, it is assumed that the position in the DVD video title can be described by five parameters of a title number and a time code (hour, minute, second, frame).

Next, a first operation example of the DVD player will be described with reference to FIG. FIG. 4 is a flowchart showing a first operation example of the DVD player.

When the DVD video title 1a is being reproduced by the DVD drive 1 (step S10 in FIG. 4)
1), the stream playback control unit 2 determines the current playback position of the title and the “position within the title” in the correspondence table 22 of FIG.
Are compared (S102).

In this case, since the stream to be reproduced contains data specifying the “position in the title” such as a title number and a time code, every time the stream reproduction control unit 2 extracts the data from the stream, the corresponding table is displayed. It is checked whether or not each item matches the item of “position in title” of No. 22.

As a result of the comparison, when the items do not match, the stream reproduction control section 2 continues the reproduction of the title stream. When the items match, the following processing is performed by the stream reproduction control unit 2, the web page display determination unit 7, the web page display unit 8, and the like.

During the playback of the title stream, any of the positions specified by the “position in the title” of the correspondence table 22 in FIG. 3, for example, the title number 1 of the first record, the time code 0 hour 1 minute 5 seconds When approaching the stream of three frames, the stream reproduction control unit 2 notifies the web page display determination unit 7 that the first position of the web page table 6 is to be reproduced.

The web page display determination section 7 compares the current parental lock level in the playback control information storage section 3 with G, which is the first group in the correspondence table 22, (S103).

At this time, the web page display determination unit 7
If the group of the web page is equal to or lower than the level of the parental lock, it is determined that the web page can be displayed, and the web page display unit 8 is notified of the item number of the web page table 6 and that it can be displayed. I do.

On the other hand, if the web page group is higher than the parental lock level, the web page display determination section 7 determines that the web page cannot be displayed,
The web page display unit 8 is notified that it cannot be displayed.

If the parental lock level at this time is “1”, that is, if it is the most general one, the web page display determination unit 7 refers to the corresponding file 21 in FIG.
Since the group R of the web page is equivalent to the level “6” in the parental lock, the level “1” in the parental lock
Higher than the web page http: //www.movie-db.
It is determined that com / war / slaughter / cannot be displayed.

If the level of the parental lock is, for example, "6", the level is the same as that of the group R of the web page. Therefore, the web page display determination section 7 sets the web page http: //www.movie-db. It is determined that com / war / slaughter / can be displayed.

Next, the operation of the web page display unit 8 and the stream reproduction control unit 2 when the web page can be displayed and when it cannot be displayed will be described. Web page display section 8
When the web page display determination unit 7 notifies that the web page can be displayed, the web page display is enabled for a predetermined time.

When the user performs an operation for displaying the web page by pressing the web display button of the key operation unit provided in the DVD drive 1 while the web page can be displayed (S104). ), The web page display section 8 displays the web address designated by the first in the web page table, that is, http: //www.movie-db.
The user accesses the web page of com / war / slaughter / and displays the content on a part or the whole of the screen of the display 5 (S105).

In this case, the web page display section 8 displays the web page on the display 5 before the web page is displayed, and determines whether the display range is a part of the screen of the display 5 or the entire screen, or The stream reproduction control unit 2 is notified of a display method such as making the web page translucent and superimposing it on the video image.
Upon receiving the notification, the stream reproduction control unit 2 determines whether to continue or stop the stream reproduction, and executes a processing operation based on the determination result.

Even if the web page can be displayed, the web page is not displayed unless the user performs an operation for displaying the web page. Become.

The time during which the web page can be displayed may be a predetermined fixed time, such as 30 seconds or 1 minute, or the like. That value may be used. Further, it may be until the next “position in the title” of the web page table 6 is reached. In the case of this last example, if there is only one “position in the title” in the web page table 6 and it indicates the beginning of the title, one web page will always be displayed during playback of the title. Page.

In the above example, in order to display the web, the user of the DVD player needs to perform a predetermined operation procedure (S104 in FIG. 2). The web page may be displayed when the user reaches the position within the title, regardless of the presence or absence of a user operation.

By changing the "web page address" described in the web page table 6, not only web sites on the Internet, but also pages recorded on the DVD title 1a and pages recorded on other storage devices are of course available. Can be displayed.

When the web page display unit 8 notifies the web page display unit 8 that the web page cannot be displayed from the web page display determination unit 7, even if the user performs the operation for displaying the web page correctly, the web page display unit 8 does not need to be displayed. Does not display web pages.

When the web page is not displayed, the web page display unit 8 does not notify the stream playback control unit 2 of anything. Continue playing.

In the correspondence table 22, if web addresses are prepared for different web groups at the same “position in the title” as in the third and fourth records, for each parental lock level, It is also possible to display a web page whose contents correspond to the level of the parental lock.

After displaying the web page, the user performs a predetermined procedure for ending the display of the web page, for example, presses a web display end button provided on a key operation unit of the DVD player to perform an operation of ending the web page display. Then, the web page display unit 8 stops displaying the web page.

At this time, what kind of processing is performed by the stream reproduction control unit 2 is not particularly defined. However, if the stream reproduction is stopped at the time of displaying the web, the stream reproduction is restarted from the stopped part. Alternatively, if the web display continues the stream reproduction only on a part of the screen, the display part may be returned to the entire screen and the stream reproduction may be continued. Further, the stream reproduction may be temporarily stopped so that the reproduction is not restarted until an instruction is given from the user.

A second operation example of the DVD player according to the first embodiment will be described. The first operation example is an example in which the parental lock function is extended to access to the web page in the correspondence tables 21 and 22 in which the parental lock level and the group added to the web page are associated. However, in the second operation example, an example in the case of a DVD title 1a having a multi-stream section will be described.

As a DVD title 1a having a multi-stream section, in addition to a parental lock function, a multi-story function in which a story is branched from the time when a user makes a selection in a multi-stream section during reproduction of a stream. A title set with multiple versions of what you have or a movie, such as the so-called theater release version, full version, director's cut version, etc., for adjusting the screening time for the performance of the box office or the production side, etc. Can be considered.

In the case of such a DVD title 1a, a list of the web page table 6 is created so as to access a different web page for each selected story or version, even at the same "position in the title".

For example, consider the case of a DVD title 1a having a multi-story function so that any one of three stories can be selected.

The three stories are named story A, story B, and story C, respectively, and the web page groups corresponding to them are A, B, and C, respectively.

In this case, the correspondence table 2 between the parental lock level and the web page group shown in FIG.
As shown in FIG. 5, a list corresponding to the multi-story and the group of the web page 2
Prepare 3

As a list corresponding to the correspondence table 22 shown in FIG. 3, as shown in FIG. 6, a correspondence table 24 of the position in the title, the address of the web page, and the web page group is prepared.

The operation of the parental lock in this case is basically the same as that of the above-described embodiment, except for the part of the determination processing of S103 shown in the flowchart of FIG. The reproduction control information storage unit 3 stores information of the selected multi-story, not the parental lock level. In the web page table 6, a list obtained by linking the correspondence table 23 and the correspondence table 24 to be normalized is set. In this case, as shown in FIG.
The stream playback control unit 2 determines whether (S
201), the position in the title of the correspondence table 24 in the web page table 6 is compared with the current reproduction position (S202).

Then, when they match each other (Y in S202)
ES), the stream reproduction control unit 2 notifies the web page display determination unit 7 that the “position in the title” (1, 0, 1, 3, 1) has been reached.

The web page display determination section 7 acquires the currently selected multi-story from the reproduction control information storage section 3 and obtains the corresponding web page group from the correspondence table 23. Here, assuming that story B is selected, B is obtained as a web page group from the correspondence table 23.

Further, the web page display determination unit 7 uses the correspondence table 24 to determine the position (1,
From among the three items (3, 1), a record in which the web page group is B is searched, and the second http: // ww
Obtain the address w.movietitle.com/story-B/ (S
203).

When the address is obtained in this manner, the web page display determining unit 7 sends the web page display unit 8
This address data and the fact that display is possible are notified.

If the position in the current title (1, 3,
If the record whose web page group is B is not in the web page table in 1), the web page display determination unit 7 determines that the web page cannot be displayed, and notifies the web page display unit 8 that the display is not possible. .

When the user performs an operation for displaying the web page by pressing the web display button of the key operation unit provided in the DVD drive 1 while the web page can be displayed (S204). The web page display unit 8 displays the web address designated by the second in the correspondence table 24, that is, http://www.movietitle.com/stor.
The web page yB / is accessed, and its contents are displayed on a part or the whole of the screen of the display 5 (S205).

Next, a third operation example of the DVD player according to the first embodiment will be described. In the second operation example, the web page to be displayed is switched for each selected title in the DVD title 1a having the multi-story. However, the DVD title 1a includes multiple languages in a multi-stream section. There are also titles corresponding to multiple languages by having audio streams and subtitle streams. When reproducing information of such a multilingual DVD title 1a, if the web page table 6 is created so as to access web pages of the same content but in different languages, the user can view the web page in a language suitable for him / her. Will be able to

For example, Japanese, English, Spanish, etc.
In the case of a DVD title 1a including audio streams in different languages, as a list in the web page table 6,
As shown in FIG. 8, a correspondence table 25 in which the selected language is associated with the web page group is prepared.

As shown in FIG. 9, a correspondence table 26 is provided which associates the position in the title with the address of the web page for each language and the web page address.

Thus, a web page corresponding to the selected language can be displayed in the same procedure as in the second operation example. In the correspondence table 26, the position in the title is an example in which the position is described with five items: title number, PGC number, program number, cell number, and elapsed time in the cell.

As described above, according to the DVD player of the first embodiment, in reproducing the information of the DVD title 1a having the multi-stream section, the web page related to the DVD title 1a and the position in the title are described. In associating the list with the stream selected in the multi-stream section and the contents of the web page, and displaying the web page corresponding to the stream selected in the multi-stream section, the parental lock applied to the title stream is changed to the web page. Can be applied based on the same criteria, so that it is possible to prohibit display of a web page that the child does not want to see.

For each title of a multi-version (for a movie, for example, theatrical release version, uncut version, director's cut version, etc.), it is possible to access different web pages even in the same scene. The degree of freedom can be increased.

Further, if the title is a multilingual title, a web page in the same language as the language being reproduced can be displayed.

Next, a DVD player according to a second embodiment of the present invention will be described. FIG. 10 is a block diagram showing the configuration of the DVD player according to the second embodiment of the present invention.
The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in the figure, this DVD player is obtained by adding a web icon control unit 10 to the configuration of the first embodiment. The web icon display unit 10 receives a notification from the web page display unit 8 as to whether the web can be displayed or not, and displays a sign indicating the content to the user.

In the first embodiment, the web page may not be displayed even if the user executes a predetermined operation procedure for displaying the web page.

The cause may be a case where the display destination address in the scene is not described in the web page table 6, a hardware failure, an erroneous operation procedure, or the like. I don't know the cause.
Further, in the case of the first embodiment, it is not clear when the user should perform the operation of displaying the web page.

For this reason, in the second embodiment, the web icon control unit 10 is provided in the configuration of the first embodiment, and the user is notified of the status when the web page can be displayed and when the web page cannot be displayed. To solve these problems.

The operation of the DVD player according to the second embodiment will be described below with reference to FIG. In the case of the DVD player according to the second embodiment, the same processing as in the first embodiment is performed (S301 to S303 in FIG. 11).

When the web page display determining unit 7 notifies the web page displaying unit 8 that the web page can be displayed, the web page displaying unit 8 notifies the web icon control unit 10 that the web page can be displayed. Do.

At this time, the web icon control section 10 displays a sign for notifying the user that the web page can be displayed, for example, a “web access icon” which is a dedicated icon for a displayable notification, on the screen of the display 5. It is displayed on the upper side for a fixed time (S305). In addition to this display mode, for example, a light-emitting diode (LED) dedicated to a displayable notification may be provided on a front panel, which is a key operation unit of a DVD player, and may be lit.

In the second embodiment, the web icon control unit 10 is connected to the display 5. However, when the display means corresponding to the “web access icon” is on the DVD drive 1 side, Is connected to the DVD drive 1.

While the "web access icon" is displayed on the screen of the display 5, when the user responds by performing a predetermined operation on the DVD player, for example, pressing a button dedicated to web access (S306). YES), the response is transmitted to the web page display unit 8 via the web icon control unit 10.

Web page display unit 8 receiving the response
Accesses the web page at the address specified in the web page table 6, and displays the content of the web page on a part or the entire screen of the display 5 (S
307).

S303 also when the web page cannot be displayed
The processing up to is the same. And web page display section 8
Notifies the web icon control unit 10 that the web page cannot be displayed.
Indicates a sign on the screen of the display 5 or D to notify the user that the web page cannot be displayed.
It is displayed on the front panel of the VD player for a fixed time (S304). This signature will be referred to herein as a "web access prohibition icon".

While the "web access prohibition icon" is displayed, even if the user presses a predetermined button of the DVD player and responds according to the procedure specified for displaying the web page, the web icon control unit 10 Since the user does not notify the web page display section 8 that the user has taken the procedure for displaying the web, the web page is not displayed on the display 5.

The web page display section 8 does not notify the stream playback control section 2 of any information since the web icon control section 10 does not notify anything. Therefore, the stream playback control section 2 executes the playback control information storage section 3 Stream reproduction is continued according to the reproduction control information.

Even if either the “web access icon” or the “web access prohibition icon” is not displayed, the user can see the display / non-display state of the other icon to find out what kind of situation, You don't need to show both icons because you understand.

As described above, according to the DVD player of the second embodiment, the web page is displayed by providing the web icon control unit 10 for displaying the “web access icon” or the “web access prohibition icon”. Since the user is notified of each of the cases where the display is possible and the case where the display is not possible, the user can immediately understand the status of whether or not the web can be accessed during the stream reproduction by looking at the display of this icon. Next, a DVD player according to a third embodiment of the present invention will be described. In the description of the third embodiment, since the block configuration is almost the same as that of the second embodiment, the description will be made with the difference in operation.

In the case of the DVD player according to the third embodiment, the display of the “web access icon” or the “web access prohibition icon” or both is performed in accordance with the group of the web pages recorded in the web page table 6. A plurality of data are prepared in the web icon control unit 10.

When the web page display unit 8 notifies the web icon control unit 10 that the web page can be displayed or cannot be displayed, the web icon control unit 10 reads the current parental lock level, multi Select a story Obtain information about a story or a multilingual language, and select a "Web access icon" or "Web access prohibition icon" that is appropriate for that information from among multiple "Web access icons" or "Web access prohibition icons". Is displayed on the display 5 or the front panel of the DVD drive 1.

In the second embodiment, regardless of the parental lock level or the stream selected by multi-story / multi-lingual, the displayed “web access icon” or “web access prohibition icon” Although the display pattern is the same, in the third embodiment, for example, when the parental lock is set at a level for children, the icon is large for children and does not include difficult words. The icons are compact and abstract when the adult level is set. Furthermore, by changing the language used for the icons in accordance with the words set in the multilingual manner, or by using a signature unique to the language, it is possible to display whether or not the Web access is easy for the user to understand.

Next, a DVD player according to a fourth embodiment of the present invention will be described. FIG. 12 is a block diagram showing a configuration of a DVD player according to the fourth embodiment of the present invention.
The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in the figure, the DVD player is obtained by adding an Internet connection control section 11 to the configuration of the first embodiment. The Internet connection control unit 11 monitors the reproduction control information storage unit 3 and the web page table 6, and disconnects the Internet connection when the need for the Internet connection is eliminated.

In the first embodiment, access to a web page on the Internet may not occur depending on the contents of the reproduction control information storage unit 3 and the web page table 6. In this case, assuming that the DVD player always maintains a connection to the Internet in preparation for accessing a web page, a dial-up connection causes an increase in communication costs associated with the Internet connection and a dedicated line. Connection increases the load on the communication system on the dedicated line side.

Therefore, in the third embodiment, during reproduction of the stream, the Internet connection control section 11 compares the reproduction control information 3 with the contents of the web page table 6, and
By automatically disconnecting from the Internet when it is determined that there is no need for an Internet connection,
Solve these problems.

In this case, as the list of the web page table 6, as shown in FIG. 13, a correspondence table 27 in which the position in the title, the address of the web page, and the web page group are prepared. The position in the title of the correspondence table 27 is a combination of a title number and a time code (the same as in FIG. 3).

In the reproduction control information stored in the reproduction control information storage unit 3, the parental lock level is set to "1", that is, the lowest level for general use and the level corresponding to G of the web page group. In this case, only the web page in the local storage device described in the third record of the correspondence table 27 can display the web page.

In this case, the Internet connection control unit 11
Examines the playback control information stored in the playback control information storage unit 3 and the contents of the web page table 6 when the DVD player is activated, and determines whether there is a possibility of Internet connection.

In the example of the correspondence table 27 shown in FIG. 13, when the parental lock level is “1”, only the web page in the local storage device is accessed.
No access to websites on the Internet occurs.

Therefore, the Internet connection control unit 11
Disconnect from the Internet. Thereafter, the Internet connection control unit 11 monitors the reproduction control information storage unit 3 and the web page table 6 independently of other processing such as stream reproduction processing, and when at least one of them is changed, the Internet connection control unit 11 connects to the Internet. Is determined again.

As a result of the re-determination, if there is no possibility of the Internet connection, the connection is cut off as it is, and if there is a possibility, the connection depends on the system in the DVD player, such as restarting the connection or preparing to restart. Perform the following processing.

Also, when a change occurs in at least one of the reproduction control information storage unit 3 and the web page table 6 in a state where the Internet connection has already been established, the Internet connection control unit 11 keeps the Internet connection. Is determined again, and if there is no possibility, the connection to the Internet is cut off.

As described above, according to the DVD player of the fourth embodiment, during reproduction of the stream, the Internet connection control section 11 compares the reproduction control information 3 with the contents of the web page table 6 and determines whether or not the Internet connection has been established. If it is determined that it is not necessary, the connection to the Internet is automatically cut off, and the DVD player is not always connected to the Internet in preparation for accessing the web page. The accompanying communication costs can be reduced, and in the case of connection via a dedicated line, the load on the communication system on the dedicated line side can be reduced.

Next, a DVD player according to a fifth embodiment will be described. The configuration of the DVD player according to the fifth embodiment is basically the same as that shown in FIG. In the first embodiment, the web pages are grouped in advance in consideration of the parental lock level for each DVD title. In the fifth embodiment, the web pages are automatically grouped.

A rating is set for a web page published by an independent non-profit public organization or the like.

If this rating is used, the value of the web page group in the web page table 6 can be automatically added, so that the work at the time of title creation can be reduced.

Hereinafter, an example in which rating is used will be described. Here, a correspondence table 28 for a web page having no web page group item as shown in FIG. 14 is prepared.

The correspondence table 28 is an example in which the position in the title is described by five items: title number, PGC number, program number, cell number, and elapsed time in the cell.

In this case, the process until the stream playback control unit 2 notifies the web page display determination unit 7 that the current playback position matches the “position in the title” of the correspondence table 28 in the web page table 6 Are the same as the processing of the DVD player of the first embodiment, that is, the processing (S101, S102) shown in the flowchart of FIG.
Here, when the web page display determination unit 7 sends an instruction to access the web page by specifying the web page address to the web page display unit 8, the web page display unit 8
Obtains rating information of a public organization for the web page via the Internet, and notifies the web page display determination unit 7 of the rating.

The web page display determining section 7 compares the parental lock level recorded in the reproduction control information storage section 3 with the rating for the web page, and determines whether or not the web page can be displayed. Notify 8.

The subsequent processing is the same as the processing after S104 in FIG.

As described above, according to the DVD player of the fifth embodiment, the value of the web page group in the web page table 6 is automatically updated by using the rating information of a public organization published on the Internet. Since it is possible to add a title, the work at the time of creating a title can be reduced.

Also, the stream reproduction control information and the parental level of each scene are read from a predetermined storage medium, for example, the DVD title 1a, etc., and while the video information is reproduced, the read stream reproduction control information and parental level are read. Based on the level and the parameters obtained by grouping the website addresses according to the parental level, it is determined whether or not the website can be searched.If the website is determined to be searchable, the website is determined. Since the search is performed, access to the website can be restricted when each scene is reproduced.

If the web page is not displayed even if the user executes a predetermined operation procedure for displaying the web page, it may be because there is no display destination address in the scene, or a hardware failure may occur. The user can understand whether the operation procedure is wrong or the operation procedure is incorrect.

Further, the notification of the search availability is changed based on the read control information.
The notification of the search availability is not left.

Further, based on the read control information,
Since communication for website search is controlled, for example, when there is no notification that a website can be searched for a long time, communication with the Internet is released to save communication costs and reduce network load. Can be reduced.

Further, when a website of a public institution exists on the Internet, rating information of a website that can be searched for each scene is obtained from the website of the public institution, and is used to determine whether the website can be searched.
