Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus and a data broadcast receiving system, and more particularly to a receiving apparatus for accessing contents on a network using content decision data multiplexed with a broadcast program, a data broadcast receiving system, The present invention relates to a content access method and a program.

[0002]

2. Description of the Related Art In recent years, the Internet (network)
Is becoming more common and its use is expanding.
Particularly, browsing of contents represented by a homepage and use of e-mail exchange are frequently performed. Furthermore, the use of the Internet using a mobile phone has recently increased, and the use of the Internet in a mobile environment using a mobile phone is now essential for user communication.

[0003] On the other hand, stationary televisions that can use the Internet are becoming widespread, and it is possible to access contents on the Internet using the stationary televisions. Since the stationary television that can use the Internet has many parts in common with the mobile phone, it is expected that the television will eventually be downsized and integrated with the mobile phone.

[0004] By the way, in using the Internet,
The problem that has conventionally been a problem is URL (Uniform Reso
urce Locater). When a user displays a homepage (content) or sends an e-mail, the user must always specify position information of the content on the Internet. As key points for the content provider to increase the browsing rate of its own content, method points such as how to input the URL to the user and frequency points such as how to provide (present) the URL to the user. Is raised.

First, a method of inputting the URL will be considered. For example, a personal computer generally inputs a URL using a keyboard having a large number of keys, while a mobile phone uses a method of assigning English characters (alphabet) to ten numeric keys and inputting the URL. . However, this method is far from efficient. Because, to enter one English character,
This is because the same numeric key is frequently pressed a plurality of times. Therefore, a method has been proposed which replaces the URL input using an English character string.

A first method is a menu selection method, a typical example of which is a link collection prepared in advance by a mobile phone provider or the like. The link collection is
This is a menu in which addresses of a plurality of contents are registered in advance. Since the link collection is prepared in advance, the user can easily display this menu when using a mobile phone. By simply selecting a desired URL from the menu, the user can browse the target content without inputting the URL.

A second method is a numeric input method. This is a method of assigning a predetermined numeric string to a URL. The user accesses a specific homepage and uses a database provided by the site. In practice, a numeric string is entered as a search key for a search function provided by the specific homepage, and the corresponding content is displayed. The user can browse the contents only by inputting the numeric keys without having to input the English characters.

A third method is a barcode input method. In this method, a predetermined barcode is assigned to a URL. The user accesses a specific homepage and uses a database provided by the site. Actually, a mechanism is provided in which a corresponding content is displayed by inputting a barcode reading result to a search function provided by the specific homepage. The user can browse the content without having to perform a troublesome key input.

The fourth method is a keyword input method. This is a method of assigning a specific keyword to a URL. As in the case of using a homepage that provides a conventional search engine, a user accesses a specific homepage and uses a database provided by the site. Actually, by inputting a keyword for the search function provided by the specific homepage, the corresponding content can be browsed.
A method of directly inputting a keyword instead of inputting a URL has also been proposed. The user can browse contents by inputting a meaningful character string instead of unfamiliar characters or numbers.

A fifth method is a multilingual input method. This is a method that allows input of URLs other than English characters. For example, change the URL to "http: /// bookstore ○
Instead of “.com”, use “http: // bookstore ○ △ .com.” Users can browse the homepage by entering not only unfamiliar English characters but also meaningful Japanese.

[0011]

The above idea can be generally regarded as a method of accessing a database prepared with keywords corresponding to URLs. It is not necessary to directly input the URL, but an input instead of the URL is still required except for the first menu method. Therefore, the following problems remain.

[0012] That is, since the user needs to memorize the URL and input once, an input error may occur.
There is an L transcription problem. This problem does not occur in the third barcode input method. However, since the third barcode input method requires a cooperative device such as a barcode reader, it is necessary to consider a trade-off between an input error and device coordination work. In addition, since most users often browse the homepage for a short time at any time,
It is generally considered that the load of the device cooperation work is larger.

In the case of the first menu selection method, the content provider generally requires various procedures to post the URL of the homepage on the menu provided by the mobile phone provider or the like. take time.

Also, the number of registered homepages is limited due to the limitation of the number of menu items. As a result, only the URL of a representative page (for example, the top page) of the home page is posted. Then, it is necessary to prepare a route for guiding the user to the homepage that the user wants to browse. In many cases, the user gets lost while following the link from the top page of the homepage, or becomes interested in another homepage, and often does not reach the content intended by the content provider.
That is, there is a so-called indirect arrival problem in which the intended homepage cannot be directly reached. In particular, when a product provided by a certain manufacturer is advertised in a broadcast program or the like, the user often uses the Internet to refer to the details of the product. In such a case, the user is not the top page of the manufacturer,
I want to display the URL of the homepage of the target product. Nevertheless, in a broadcast program, the URL of the top page is displayed for display reasons or the URL transfer problem, and as a result, the indirect arrival problem becomes conspicuous.

[0015] Further, when the URL of the homepage of the product is directly displayed in the broadcast program, the user can surely reach the homepage of the product, but the other homepage provided by the maker (content provider) is displayed. The chances of visiting the user are definitely reduced, ie there is a direct reach problem. This is something that content providers want to avoid.

As described above, in the URL input, even if the input is somewhat simplified, the above-described URL is used.
There are posting problems and indirect reaching problems. Also, the URL of the target content to solve the indirect arrival problem
In the case where is directly displayed, there is a so-called direct arrival problem that a user's chance to visit another homepage is reduced.

Therefore, the present invention solves the above-mentioned URL transfer problem and the above-mentioned arrival problem, and enables a user to easily reach a target content, a data broadcast receiving system, a content access method, and a program. The purpose is to provide.

[0018]

The present invention employs the following means to achieve the above object. That is, the present invention is based on a receiving device that receives a broadcast program.

Here, the broadcast receiving means constituting the receiving device receives broadcast data obtained by multiplexing content determination data for determining the position of the content arranged on the network and a broadcast program related to the content. . Subsequently, the separating means separates the content determination data and the broadcast program from the received broadcast data, and accesses the content based on the content determination data separated by the data communication means.

With the above arrangement, the user can easily obtain content determination data (eg, URL) with one button without using input means such as a keyboard and access the content corresponding to the content determination data. it can. Therefore, the user does not need to remember and input the URL once, that is, it is possible to solve the above-described URL transfer problem.

When the broadcast data includes a plurality of pieces of content determination data, the separating means separates the plurality of pieces of content determination data from the broadcast data, and the data management means separates the plurality of pieces of content determination data from the plurality of pieces of content determination data.
One or more content determination data based on a predetermined condition is selected. The data communication unit accesses the content based on the content determination data selected by the data management unit. Note that the predetermined condition may be, for example, a voice type selected by the user.

With the above arrangement, the content determination data obtained by the user can be automatically changed based on a certain condition (for example, audio type), and the user can adjust the content according to the audio of the broadcast program being viewed. By obtaining the decision data, the user can easily access the homepage indicated by the URL.

Still further, when the broadcast data includes a plurality of pieces of the content determination data and scenario data indicating an order of use of the content determination data, the separating means separates the plurality of pieces of the content determination data and the scenario data from the broadcast data. To separate. Next, the data management means sequentially selects a plurality of separated content determination data based on the same separated scenario data, and the data communication means sequentially selects the content based on the selected content determination data. To access.

With the above arrangement, the above URL transfer problem can be solved, and the user can access predetermined contents based on the intention of the sender. Therefore, the user can surely reach the homepage in which the user is interested. In addition, for companies that provide homepages, users can use other homepages,
Can be browsed. As a result, it is possible to solve the above-mentioned reaching problem.

Note that the content determination data may be a group of keywords capable of specifying the content other than the URL.

Further, the receiving device can be configured as two different receiving devices, that is, a data broadcast receiving system. That is, the data broadcast receiving system includes:
A first receiving device comprising the broadcast receiving means, the separating means, and a data transmitting means for transmitting the content determining data separated by the separating means; and the content determining means received from the content determining data transmitting means. It comprises a second receiving device including a data transmitting / receiving means for accessing the content based on data.

In this configuration, for example, when a broadcast program is displayed on a street display, and the broadcast program can be viewed by an unspecified number of people, the unspecified number of people can view the broadcast program. For example, an operation of acquiring content determination data using a mobile phone or the like can be performed. In this operation, the unspecified large number of people can use a mobile phone or the like to display the content corresponding to the broadcast program currently being viewed with a single button, for example.

The receiving device can be embodied using a computer. In that case, the broadcast receiving means,
The separation unit, the data management unit, the data communication unit, the data transmission unit, and the data transmission / reception unit are embodied by running a program on a computer.

[0029]

Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention.
It should be noted that the following embodiments are examples embodying the present invention, and do not limit the technical scope of the present invention.

[First Embodiment] First, an overall outline of a receiving apparatus according to a first embodiment will be described with reference to FIG. The data broadcast receiving system includes a broadcast station 100, a receiving device 110, and a Web server 130 connected by wire or wirelessly.

The broadcasting station 100 includes a normal broadcasting program,
The content determination data related to the broadcast program is multiplexed and broadcast as broadcast data. Here, the content determination data related to the program is, specifically, a URL for determining the position of the content arranged on the network (Internet). The URL is, for example, We
It is obtained by transferring from the b server 130 to the broadcasting station 100. The content is information published on a network and refers to, for example, text, still images, moving images, and the like stored in a web server. A homepage or the like is used as a representative public technique of the content.

[0032] The receiving device 110 is a
Receives broadcast data broadcasted by the user, and can display a normal broadcast program and content determination data related to the broadcast program on a display or the like provided in the receiving device 110, for example.

Further, the receiving device 110 has an Internet connection function. That is, the receiving device 110 receives the content determination data transmitted from the broadcasting station 100, accesses the Web server 130 based on the content determination data, acquires, for example, the contents of a homepage, and displays the content on a display or the like.

Here, as the receiving device 110, for example, a mobile phone is used, but it is not particularly limited, and any receiving device having the function of the receiving device 110 may be used. Specifically, it can be a PDA (Personal Data Assistant) or a personal computer.

Next, the configuration and processing of the broadcasting station 100 will be described in detail with reference to FIG. The broadcast station 100 broadcasts the broadcast program 10
1 and the content determination data 102
3 is combined into one broadcast data, and the broadcast means 10
4 to broadcast.

Here, the broadcast program 101 is video or audio data that can be output on a normal television or radio, or data of a combination thereof. The details of the content determination data 102 will be described below.

That is, the content determination data 102
Is the First_PTS 300, L, as shown in FIG.
ast_PTS301, actual content number (num) 30
2 and a plurality of real contents 303. Here, the First_PTS 300 indicates the time at which the content determination data 102 is reproduced by the receiving device 110. Last_PTS 301 indicates the time at which reproduction of the content determination data 102 ends at the receiving device 110.

Therefore, the content determination data 102 is F
It can be valid only in the time section of the first_PTS 300 and the Last_PTS 301.

Therefore, the First_PTS 300 and the Last_PTS 300 are set at the playback time (broadcast time) of the broadcast program 101.
By matching the value of the PTS 301, a predetermined broadcast program can be temporally associated with predetermined content determination data.

The num 302 is the actual content (Content_d) included in the content determination data 102.
ata). The real content 303 is a unit for storing the real content data, and the real content data covers various types, for example, as shown in type 304 in FIG. The method of using the actual content data will be described later.

The actual content further includes an actual content type (type) 304 and an actual content length (len) 3
05, actual content data (data) 306. The real content type 304 indicates the data type of the real content data 306, and the real content length 305 indicates the data length of the real content data 306 in bytes. The actual content data 30
6 is the multimedia content itself.

A specific value stored in the type 304 is represented by a value 400 shown in FIG. 4, for example, and has the following meanings.

When type 304 = "0", the data type 401 is "
In this case, the actual content data further has the same format as the content determination data. In the case of type 304 = "1", the data type 401 is "
The description of the URL is ". The description of the URL is a sentence for explaining the URL when the URL character string alone does not indicate the URL. For example, type 304 =" 2 " In this case, the data type 401 is "
URL ". When type 304 =" 3 ", the data type 401 is"
JPEG (Joint Photographic Experts Group) ". The JPEG is a general image format. When type 304 =" 4 ", the data type 401 is"
AUDIO ". When the type 304 =" 5 ", the data type 401 is"
VIDEO ". When the type 304 =" 6 ", the data type 401 is"
Position information ". The position information corresponds to the U
For example, the coordinates of a store related to the RL are stored. When the type 304 = "7", the data type 401 is "
The index number is described below. Note that the index number will be described later. If type 304 = "8", the data type 401 is "
It indicates that the data is scenario data ". If the type 304 =" 9 ", the data type 401 is"
The scenario data and the scenario number will be described later. If type 304 = "10" or later, data type 4
01 is "undefined", and the content determination data provider can newly define an arbitrary data type using the value.

According to the structure of the content determination data 102, the content determination data 102 can transmit various data to the user in synchronization with the broadcast program. The broadcasting of the broadcast program and the content determination data by the broadcasting station 100 is performed as follows using the structure of the content determination data. That is, in FIG. 7, the commercials A (CM-
If the start time of A701) is T1 and the end time is T2, the First_
The above T1 is set in the PTS 100, and Last_PTS1
01 is stored and broadcast. In the data 306 in the content determination data 704, for example, a URL related to the commercial A is stored. Similarly, in the content determination data 705 corresponding to the program 702 constituting the broadcast program 700, First Content
_PTS100 with T2, Last_PTS101 with T
3 is stored. The actual content data 306 of the content determination data 705 includes, for example, the program 702.
Is stored. Note that, for example, when one commercial is broadcast, a plurality of pieces of content determination data may be switched midway and transmitted (multiplexed).

As described above, the content determination data 102 having the above structure is multiplexed from the broadcast station 100 into a broadcast program and broadcast as broadcast data.

Next, the details of the processing after the reception device 110 receives the broadcast data will be described with reference to FIGS. 5, 6, 7, and 8. FIG.

The broadcast receiving means 501 constituting the receiving apparatus 110 receives broadcast data broadcast from the broadcasting station 100 and transmits the broadcast data to the separating means 502 (FIG. 6: S601). Subsequently, the separation unit 502 that has received the broadcast data sets the multiplexing unit 1 of the broadcast station 100.
The broadcast program 503 and the content determination data 506 included in the broadcast data are separated by using a method corresponding to the method used in FIG. 03 (FIG. 6: S602).

Next, the separated content determination data 5
06 is temporarily stored in the reception buffer 510 constituting the data management means 507 (FIG. 6: S603).

The separated broadcast program 503 is
For example, it is transmitted to the program reproducing means 504 as it is. The program reproducing means 504 reproduces the received broadcast program in accordance with the format of the broadcast program, and the reproduced broadcast program is displayed via the display means 509 such as a display (FIG. 6: S604).

Here, the case where the broadcast program 700 shown in FIG. 7 is specifically reproduced will be considered. The broadcast program 70
0, for example, the CM-A 701
Is played back at T1 shown in FIG.
Note that the time T1 is, for example, immediately after the broadcast receiving unit 501 receives the CM-A 701.

On the other hand, the data management means 507 stores the First_PTS 300 and Last_P of the content determination data 704 stored in the reception buffer 510.
Read TS301. Here, the above First_PT
Time T1 is stored in S300, and time T2 is stored in Last_PTS301. Therefore, at the time T1, the data management unit 507 moves the content determination data 704 to the temporary buffer 511 and displays the actual content data stored in the data 306 of the content determination data 704 on the display unit 509 ( (FIG. 6: S605 → S606).

As described above, the CM-A7 of the broadcast program 700
01, and data30 of the content determination data 704
6 (eg, UR)
L) is simultaneously displayed on the display means 509, and the user can view the broadcast program and the actual content data related to the broadcast program. The reception buffer 510
The content determination data stored in the temporary buffer 511 is stored in the data management unit 50 at the time T2.
7 and the broadcast data is not ended, and the process is repeated again from the process of separating the broadcast program and the content determination data (FIG. 6: S607 → S609No → S602). Naturally, the reproduction of the broadcast program also ends at time T2, and if the broadcast program does not end, the next broadcast program is reproduced at any time (S608 → S609No → S602).

The actual content data stored in the content determination data may be, for example, video (moving image / still image), audio, URL, etc.
By combining a plurality of real contents included in the content determination data, video, audio, and URL
Can be displayed in combination. However, the content determination data includes at least one of the URs.
L and the above keyword group that can determine the position of the content.

Next, it is assumed that the user 140 is very interested in the contents of the broadcast program while watching the broadcast program (for example, a commercial). Then, the user presses a predetermined button provided on the receiving device 110, for example, so that the instruction receiving means 51 constituting the receiving device 110 is pressed.
3 is instructed to take in the content determination data (to create a bookmark). Instruction receiving means 513 receiving the above instruction
Transmits to the data management unit 507 that the instruction has been received, and the data management unit 507 stores the content determination data stored in the temporary buffer 511 in the holding list 512 when the predetermined button is pressed. It is stored (FIG. 8: S801).

As described above, when the user is interested in the contents of the broadcast program when browsing the broadcast program, the content determination data (for example, URL) related to the broadcast program
Can be easily stored as a bookmark without using a keyboard or the like.

The content determination data stored in the holding list 512 is used as follows. That is, the user 140 presses a predetermined button or the like to select the content determination data stored in the holding list 512, for example. The press of the button is notified to the data management unit 507 via the instruction receiving unit 513, and the data management unit 507 displays all of the content determination data stored in the holding list 512 on the display unit 50.
9 (FIG. 8: S802). The user 140 watching the display selects desired content determination data in the display by, for example, pressing a cross key or the like, and presses a predetermined determination button. The press of the decision button is transmitted to the data communication unit 508 via the instruction receiving unit 513,
The data communication unit accesses the Web server 130 using the selected content determination data, and acquires a content corresponding to the content determination data (FIG. 8: S803). The acquired content is displayed on the display unit 509, and as a result, the user can browse the content corresponding to the content determination data stored in the holding list 512 (FIG. 8: S804). still,
The procedure by which the data communication unit 508 acquires the content from the Web server 130 and displays the content on the display unit 509 may be a conventional method, and thus the description is omitted here.

As described above, the user can easily acquire the content determination data (eg, URL) with one button without using an input means such as a keyboard, and access the content corresponding to the content determination data. it can. Therefore, the user does not need to remember and input the URL once, that is, it is possible to solve the above-described URL transfer problem. In addition, since the user does not need to memorize the URL or take notes, the user does not have to interrupt the viewing of the broadcast program.

The content determination data is a URL
However, the present invention is not limited thereto, and may be, for example, a keyword group including a plurality of keywords or a predetermined numeric string. In this case, the data communication unit 508 once transmits the obtained content determination data to a Web server having a predetermined database, and accesses the predetermined content using the URL obtained from the Web server. .

The First_PTS 100 may store not a time but an ID that can be uniquely associated with a broadcast program. In this case, at the time of reproducing the broadcast program, the program reproduction means 504
, The ID of the broadcast program included in the broadcast program to be reproduced is transmitted. Subsequently, the data management means 507
By selecting the received ID and the content determination data corresponding to the received ID from the reception buffer 510 and copying it to the temporary buffer 511, the broadcast program and the content determination data can be displayed simultaneously. By using the ID, for example, even if the broadcast data is once recorded, the same processing as when the broadcast program is received and reproduced as it is can be performed. When an ID is stored in the First_PTS 100, the Last_PTS 101 is not always necessary.

Further, after temporarily storing the content determination data in the holding list 512 in accordance with a user's instruction,
Although the corresponding content has been acquired, the content may be directly acquired from the Web server based on the content determination data stored in the temporary buffer 511 according to a user's instruction without temporarily storing the content in the holding list 512. .

Note that the content determination data does not necessarily need to be displayed on the display means 509.

[Second Embodiment] Next, a receiving apparatus according to a second embodiment will be described with reference to FIG. 4, FIG. 5, FIG. 9, and FIG. In the second embodiment, content determination data is selectively obtained from a plurality of pieces of content determination data to be broadcast based on the sound of a broadcast program being viewed by a user. Note that the second embodiment has many points in common with the first embodiment, and thus the common points are omitted.

First, prior to the detailed description, an outline of the selective acquisition of the content determination data based on the sound will be described. FIG. 10 shows a display example of the display unit 509 of the receiving apparatus 110. In the display 1001, a Japanese voice (main voice) is output. In addition, in the display 1004, audio output of English audio (sub audio) is performed, and the Japanese audio output and the English audio output can be selected by the user. If the user obtains, for example, a URL as content determination data during the output of the Japanese voice, the description in Japanese shown on the display 1002 and the URL 1003 (http: /
/www.panda-j.com) is automatically obtained. The acquired description and homepage are added to, for example, a bookmark, or the content corresponding to the URL is directly acquired from the Web server. Similarly, during the output of the English voice, the user determines that the content determination data is, for example, U
When the RL is acquired, the description in English shown on the display 1005 and the URL 10 of the homepage created in English
06 (http://www.panda-j.com) is automatically obtained. The acquired description and homepage are added to, for example, a bookmark, or the content corresponding to the URL is directly acquired from the Web server.

The above is a description of the receiving apparatus 11 according to the second embodiment.
It is an outline of the functions that 0 has.

Next, the structure of the content determination data for selectively acquiring the content determination data based on the sound described above will be described.

In FIG. 9, the content determination data 90
0 is a First_PTS 901 and a Last_PTS 90 indicating a valid time of the content determination data 900.
2 and further stores actual contents 904 and 905. The real content 904 stores a URL related to a Japanese homepage corresponding to the main voice Japanese voice in the form of content determination data. On the other hand, the actual content 905 stores the URL of the English homepage corresponding to the English audio as the sub audio in the form of content determination data. Therefore, “2” is stored in the actual content number 903 in the content determination data 900. In the real content types 906 and 909, “0” indicating that the real content data 908 and 911 is content determination data is stored.

Next, the structure of the real content data 908 and 911 in the real content 904 and 905 will be described.

First_PTS 912 and Last_PTS 91 constituting the content determination data 908
