An increasing number of people enjoy content and data communication content (see Non-Patent Document 1).

  As shown in FIG. 8, this one-segment broadcasting distributes broadcast contents (video / audio information of TV programs and BML data broadcast contents) by broadcast waves 22 emitted from the broadcasting facility 20 of the broadcasting station 12, and It is equipped with a mechanism that is received by the tuner of the mobile phone 34 and viewed through the BML browser.

FIG. 9A shows a BML browser 40 displayed on the display of the mobile phone 34, and includes a video display area 42, a caption display area 44, and a data display area 46.
At this stage, only BML content information via the broadcast wave 22 is displayed on the BML browser 40. On the other hand, when the user selects an arbitrary anchor button α in the data display area 46, the BML content linked to the anchor button α is transmitted from the BML communication server 14 through the mobile packet network 50, as shown in FIG. 9 (b). As shown in the data display area 46.
At this stage, communication data as well as broadcast data is displayed on the BML browser 40, but the video of the program is displayed as it is in the video display area.

  The BML content distributed by the above communication includes an anchor button β linked to the web page. When the user selects this, the web browser program installed in the mobile phone 34 is launched, As shown in FIG. 9 (c), the web content transmitted from the linked web server 16 is displayed on the web browser 56.

At this stage, since the BML browser 40 is switched to the mobile web browser 56, the video and audio of the broadcast program are interrupted.
When the web browser 56 is terminated, the browser is switched to the BML browser 40 again, and the user can continue to watch the broadcast program.

FIG. 1 is an overall configuration diagram of a content distribution system 10 according to the present invention. This system 10 includes a broadcasting station 12, a BML communication server 14, and a plurality of Web servers 16.
The BML communication server 14 is managed by the broadcast station 12. The web server 16 also includes a web server managed by the broadcast station 12.

The broadcast station 12 includes a broadcast content storage unit 18 and a broadcast facility 20.
The broadcast content storage unit 18 stores program content including video and audio, and BML data broadcast content (text + still image).
These broadcast contents are distributed on the broadcast wave 22 from the broadcast facility 20.

The BML communication server 14 includes a BML communication control unit 24, a content generation unit 26, an RSS reader 28, a user DB 30, and a program related information DB 32.
The BML communication control unit 24, the content generation unit 26, and the RSS reader 28 are realized by the CPU of the BML communication server 14 executing a dedicated application program.

Program related information such as title, channel, performers, scheduled broadcast date and time, sponsor name, sponsor's RSS feed (URL), RSS feed (URL) of related products, etc. are registered in advance in the program related information DB 32. Has been.
In editing the program related information, EPG (Electronic Program Guide) data can be used.

The user DB 30 stores data related to a user (viewer) who has registered as a member in advance through a mobile site or a PC site.
FIG. 2 shows an example of data items set in the user DB 30. The terminal ID, account name, password, gender, age range, occupation, family structure, hobby preference, distribution desired category, distribution desired site, keyword , Bookmark items are set.

A user who desires to use the service by the system 10 obtains in advance a mobile phone 34 equipped with a Web browser and a BML browser and having a mobile packet communication function and a one-segment broadcasting reception function.
Further, the user accesses the BML communication server 14 of the broadcasting station from the mobile phone 34 in advance in order to use the individually customized BML data communication service (tentative name “MyBML”), and completes user registration.
At this time, the terminal DB, account name, password, gender, age group, job category, family structure, hobby preference, distribution desired category, distribution desired site, and keyword information are stored in the user DB 30.

Hereinafter, the content distribution procedure by the system 10 will be described according to the flowchart of FIG.
First, when the user activates the BML browser on the mobile phone 34 (S10), the tuner of the mobile phone 34 receives the broadcast wave from the broadcast station 12, and as shown in FIG. Is displayed on the display (S12).

The BML browser 40 includes a video display area 42 where a moving image is played back, a subtitle display area 44 where a supertitle is displayed, and a data display area 46 where the contents of the data broadcast are displayed.
In the data display area 46, a “MyBML” button 48 is displayed in addition to general information about the program and broadcasting station such as “previous synopsis”, “performer”, and “program guide”.

Here, when the user selects the “MyBML” button 48 (S14), the BML browser of the mobile phone 34 accesses the BML communication server 14 through the mobile packet network 50 and requests distribution of the dedicated page of the user (S16). ).
Receiving this, the BML communication control unit 24 of the BML communication server 14 searches the user DB 30 using the terminal ID of the mobile phone 34 as a key, and reads the personal information of the user (S18).
The content generation unit 26 that has received the registration information from the BML communication control unit 24 passes the keyword registered in advance by the user to the RSS reader 28 and requests acquisition of RSS update information.

Receiving this, the RSS reader 28 collects RSS update information including the keyword from the RSS feeds 54 of the plurality of Web servers 16 via the Internet 52 (S20).
For example, when the user registers “health” and “diet” as keywords in the user DB 30, the RSS reader 28 refers to the RSS feed of each Web server 16 and acquires update information including the corresponding keyword.

The content generation unit 26 that has acquired the RSS update information from the RSS reader 28 generates BML content including the list of the RSS update information, and transmits it to the user's mobile phone 34 through the mobile packet network 50 (S22).
As a result, as shown in FIG. 4B, the RSS update information list 47 of the field in which the user is interested is displayed in the data display area 46 of the display (S24).
When the user selects a specific title (S26), the Web browser is activated on the display of the mobile phone 34 (S28), and at the same time, a Web file distribution request is transmitted from the Web browser to the corresponding Web server 16. (S30).

Receiving this, the Web server 16 transmits the corresponding Web file to the mobile phone 34 (S32).
As a result, as shown in FIG. 4 (c), the target web page is displayed on the web browser 56 of the mobile phone 34 (S34).

  When switching from the BML browser 40 to the web browser 56, the display of the program content in the video display area 42 will be interrupted, but it is not the dressing information prepared by the broadcast station 12, but the user himself has registered Since the information is in the desired field, the probability that the user interrupts the program and accesses the Web server 16 can be increased.

  The broadcasting station 12 concludes an affiliate contract with the merchandise seller to receive a few percent of the profit when the user purchases the merchandise through the web server 16, thereby creating a new non-advertising fee revenue. It can be used as a source of income.

In the above example, the RSS feed 54 of each Web server 16 is simply searched based on the registered keyword of the user. However, the RSS update information can be filtered in conjunction with the program.
In this case, the time when the user accessed the BML communication server 14 is combined with the EPG data, and the BML communication control unit 24 specifies the program that the user is currently viewing.
Next, the content generation unit 26 refers to the program related information DB 32 and identifies the sponsor of the program and the RSS feed 54 of the related product.
Next, the RSS reader 28 accesses the RSS feed 54 and acquires the latest update information.
Next, the content generation unit 26 generates a list including the RSS update information.
Finally, the BML communication control unit 24 transmits this list to the mobile phone 34.
As a result, in the data display area 46 of the mobile phone 34, the program sponsor and the RSS update information of the program related product are displayed.

  The content generation unit 26 prepares a plurality of keywords corresponding to the user's gender, age group, occupation, family structure, hobbies, and desired categories in advance, and selects RSS update information to be distributed to the user based on these keywords. You can also

  In addition, when the user registers the URL of the desired distribution site in advance, the content generation unit 26 collects update information from the RSS feed 54 of the target website via the RSS reader 28, and includes the RSS including these. An update information list is generated and distributed to the mobile phone 34 of the user.

Users can bookmark interesting information and browse web pages slowly after the program is over.
In the following, the bookmark function of the system 10 will be described with reference to the flowcharts of FIGS.

First, when the user selects the “bookmark” button 60 on the screen of FIG. 4B, a bookmark request is transmitted from the BML browser to the BML communication server 14 (S40).
Receiving this, the content generation unit 26 of the BML communication server 14 generates an RSS update information list for bookmarks and transmits it to the mobile phone (S42).

As a result, an RSS update information list for bookmarks is displayed on the BML browser of the mobile phone (S44).
As shown in FIG. 7, in the bookmark RSS update information list 62, the titles of the same update information as in FIG. 4B are displayed, but a check box 64 is provided for each title.

  On the other hand, when the user checks the check box 64 of arbitrary update information and selects the “save” button 66 (S46), the BML communication control unit 24 that has received this checks the title of the update information checked by the user. , URL, date and time bookmark data is stored in the user DB 30 (S48).

In this case, after the program ends, the user requests the BML communication server 14 of the broadcast station 12 to display a bookmark through the BML browser (S52).
Upon receiving this, the BML communication server 14 of the broadcasting station acquires the bookmark data of the user from the DB 30 (S54), and transmits the BML content including the bookmark data to the mobile phone 34 (S56).
As a result, the bookmark list is displayed on the BML browser of the mobile phone 34 (S58).

On the other hand, when the user selects one of the RSS update information that has been bookmarked (S60), the web browser is started (S61) and at the same time, the web file is delivered from the web browser to the corresponding web server 16. The request is transmitted (S62), and the corresponding Web file is distributed from the Web server 16 to the mobile phone 34 (S64).
As a result, the target web page is displayed on the web browser of the mobile phone 34 (S66).

  In this way, by using the bookmark function, the user can access the target website after the program broadcast ends, and there is no need to interrupt the program viewing, so the user can be guided to the website more smoothly. It becomes possible.
