In the program list 303, a vertical axis 304 indicates a broadcasting time of a program and a horizontal axis 305 illustrates a broadcasting station. In
The program list display controller 7 displays a region including a name of any one of selected programs in the program list 303 so as to be distinguished from a region including a name of a program which is not selected. Even when a user does not specifically manipulate, the program list display controller 7 considers that a specific program such as a program having a name written in a left uppermost region of the program list 303 is selected and displays a region having the name of the program which is considered to be selected so as to be distinguished from a region including a name of a program which is not considered to be selected. In
The program selecting unit 15 accepts the selection of one program from the program list 303 displayed on the screen 300A of the display device 300. For example, the program selecting unit 15 accepts the selection of one program of the program list 303 from the remote controller 100B. If the selection of one program is accepted, the program selecting unit 15 outputs the selection result to the program list display controller 7. The program list display controller 7 displays the region including the name of the selected program in accordance with the selection result of one program from the program selecting unit 15 as described above so as to be distinguished from a region including names of the other programs.
For example, the program list 303 is displayed on the screen 300A. If any one program is already selected, the user presses any one of buttons of an arrow keypad 34 of the remote controller 100B. The detecting unit which is not illustrated and mounted in the remote controller 100B detects whether any of upper, lower, left, and right buttons is pressed whenever the button is pressed once. The infrared transmitting unit which is not illustrated and mounted in the remote controller 100B transmits the detecting result to the program selecting unit 15 by the infrared ray. The program selecting unit 15 receives the detecting result from the remote controller 100B and determines a program of a name written in a region which moves up/down or left/right from a region including a name of a program selected from the program list 303 by that time as a newly selected program based on the detecting result and encloses the program with a thick solid line.
Specifically, under the circumstance where the program list 303 of
The extracting unit 16 extracts a keyword related to the program corresponding to the selection finally accepted by the program selecting unit 15 from the program information stored by the broadcasting data storing unit 4 or from the program information stored by the program information storing unit 11. For example, the keyword related to the program is a name of the program. An extracting rule that specifies whether to extract data of which items related to the program as a keyword is assigned to the extracting unit 16 in advance. The extracting unit 16 extracts the data of any one item related to the program as a keyword in accordance with the extracting rule. The rule may be set or changed by the user.
After the program selecting unit 15 receives a status where a specific program is selected, as illustrated in
The site name selecting unit 18 selects and determines a name of one site from the list 308 of the names of the shopping sites displayed on the program list 303 of the screen 300A of the display device 300. First, the site name selecting unit 18 accepts the selection of the name of one of sites in the list 308 of the names of the shopping sites by manipulating the up and down buttons of the arrow keypad 34 of the remote controller 100B by the user. The site name selecting unit 18 outputs information indicating which site's name is selected to the site name display controller 8 in accordance with the name of the selected site. The site name display controller 8 displays the region including the name of the selected site in the list 308 in accordance with the information indicating which site's name is selected from the site name selecting unit 18 so as to be distinguished from the regions including the names of the other sites. For example, the region is displayed so as to be enclosed by the thick solid line in
Even though the user does not manipulate anything, the site name display controller 8 considers that a name of a specific site such as a name of a site which is written in the uppermost region of the list 308 is selected and displays the region including the name of the site considered to be selected so as to be distinguished from the region including the name of the site which is not considered to be selected.

More specifically, in each of the meta tags, a character string continuous to “shopping-site 1=” is the name of the shopping site. For example, in the first meta tag, “shopping-site 1=“laplata.co.jp”” is written, which indicates that the name of the shopping site is “laplata.co.jp”. In the html text of
The html text of
For example, when the user selects the program of the name of “Journey of Japanese Gourmet”, the extracting unit 16 extracts “Journey of Japanese Gourmet” which is the name of the program as a keyword, and the user selects the shopping site of the name called “laplata.co.jp”, the generating unit 19 of
As apparent from the html text of
Since “the character string interposed between the symbols” “next to start= of the meta tag” is “start=“http://www.laplata.co.jp/s/keywords=””, the generating unit 19 extracts “http://www.laplata.co.jp/s/keywords=” from the meta tag as “the character string interposed between the symbols” “next to start=”.
Next, since “the character string interposed between the symbols” “next to encode=” of the meta tag is “SJIS”, the character code used when the keyword is converted is “shift JIS”. Therefore, the generating unit 19 represents “Journey of Japanese Gourmet” extracted by the extracting unit 16 as a keyword by a character code of “shift JIS”. In other words, the generating unit 19 converts the keyword called “Journey of Japanese Gourmet” into “0x93, 0xfa, 0x96, 0x7b, 0x83, 0x4f, 0x83, 0x8b, 0x83, 0x81, 0x82, 0xcc, 0x97, 0xb7”. Further, “0x93, . . . , 0xb7” are written using a hexadecimal notation method of a C language. Further, the generating unit 19 URL-encodes the character string obtained by a specified character code. In the above example, the character string of “%93% fa%96% 7b%83O%83% 8b%83% 81% 82% cc%97% b7” is generated. Further, as described above, the specified character code is defined in the meta tag for every shopping site, and a character code which is specified for a shopping site of a name called “mahoo shopping” is “EUC (extended unix code: “unix” is a registered trade mark.)”.
Next, the generating unit 19 recognizes that “a character string interposed between the symbols” “next to tail=” of the meta tag is not present.
Finally, the generating unit 19 generates “http://www.laplata.co.jp/s/keywords=%93% fa%96% 7b%83O%83% 8b%83% 81% 82% cc%97% b7” as the acquisition objective information for obtaining the information of the webpage related to the keyword called “Journey of Japanese Gourmet” in the shopping site called “laplata.co.jp” in accordance with the acquisition objective information generating rule. Further, in the first embodiment, the acquisition objective information is a URL for obtaining a search result of a webpage related to the keyword extracted by the extracting unit 16 in the shopping site selected by the user.
The site accessing unit 20 obtains the information of the webpage related to the keyword called “Journey of Japanese Gourmet” in the shopping site called “laplata.co.jp” using the acquisition objective information generated by the generating unit 19. In other words, in the first embodiment, the site accessing unit 20 obtains the search result of the webpage related to the keyword called “Journey of Japanese Gourmet” in the shopping site of the name called “laplata.co.jp” using the acquisition objective information generated by the generating unit 19. The webpage information display controller 9, as illustrated in

The webpage information display controller 9 displays the information of the webpage related to the keyword extracted by the extracting unit 16 in the shopping site having the name finally determined by the site name selecting unit 18, which is obtained using the acquisition objective information (URL), on the screen 300A of the display device 300 through the image display controller 5 (S11).
As described above, the television broadcast receiving device 100 displays the program list, selects and determines one program from the program list, and extracts a keyword related to the selected and determined program from the program list. The television broadcast receiving device 100 receives the instruction to display the shopping site from the user to display the name of one or more registered shopping sites, and selects and determines a name of one shopping site among the one or more registered shopping sites. Therefore, the television broadcast receiving device 100 generates the keyword extracted so as to be related to the selected and determined program and the acquisition objective information (URL) for obtaining the information of the webpage related to the extracted keyword in the shopping site having the selected and determined name. By doing this, even though the configuration of the query character string for the same shopping site is varied with the time, if the definition of the site information providing device of
Further, in above-described first embodiment, the functional configuration of the television broadcast receiving device 100 is described with reference to
Further, as described with reference to
Further, in the first embodiment, four shopping sites are specifically described as the shopping site, but the number of shopping sites may be arbitrary. Further, in the first embodiment, an example that uses a shopping button of the remote controller 100B when the name of the shopping site is displayed on the screen 300A of the display device 300 is described. However, other means may be used. For example, a means that displays a GUI on the screen 300A and displays the name of the shopping site on the screen 300A of the display device 300 by manipulating the GUI may be used.
The acquisition objective information generating rule which is used to allow the generating unit 19 to generate the acquisition objective information is not limited to the above-mentioned rule. For example, the rule may be a rule that switches the arrangement of the shopping site and the keyword or a rule that encrypts a part of the character string. In short, the acquisition objective information generating rule may be a rule for generating the acquisition objective information for obtaining the information of the webpage related to the keyword extracted by the extracting unit 16 at the site selected by the user.
Further, even though an example that uses the URL as the acquisition objective information is described, the present invention is not limited thereto, but other information such as information combining the URL and a User Agent may be used.
Furthermore, the keyword extracted by the extracting unit 16 is not limited to the name of the program. The keyword may be a performer of the program or the name of a land where the program is captured. The shopping site may be substituted with other types of web sites. For example, the shopping site may be substituted with a homepage of the performer.
Next, the configuration of a television broadcasting system according to a second embodiment will be described with reference to

The storing unit 82 of the acquisition objective information generating device 201 stores names and address information of four shopping sites and an acquisition objective information generating rule for generating acquisition objective information for obtaining the information of the webpage related to an assigned keyword in one of one or more registered shopping sites. The storing unit 82 individually stores the names of the registered shopping sites, the address information thoseof, and the acquisition objective information generating rule, not in one text.
The names of the registered shopping sites stored by the storing unit 82 will be described with reference to
The site information obtaining unit 12 of the television broadcast receiving device 101 according to the second embodiment accesses the acquisition objective information generating device 201 through the Internet 500 in order to obtain the names of one or more registered shopping sites. In this case, the communicating unit 81 of the acquisition objective information generating device 201 transmits the text file of shoppingsite.html of
Similarly to the first embodiment, the extracting unit 16 extracts the keyword, and the site name selecting unit 18 accepts the name of one shopping site. By doing this, the site accessing unit 20 accesses the text file of URLtransfer.html stored by the storing unit 82 of the acquisition objective information generating device 201 through the Internet 500. The text file of URLtransfer.html, as described above, is a file that defines the acquisition objective information generating rule.
In this case, in order to allow the acquisition objective information generating device 201 to generate the acquisition objective information, the site accessing unit 20 adds the name of one shopping site which is selected and determined by the site name selecting unit 18 and the keyword extracted by the extracting unit 16 to access information to access the text file of URLtransfer.html stored by the storing unit 82 of the acquisition objective information generating device 201. Specifically, the site accessing unit 20 sets the name of the shopping site and the extracted keyword as parameters in a query string of the URL of the text file of URLtransfer.html.
More specifically, if it is assumed that the URL of the text file of URLtransfer.html is “http://www.URLServer.co.jp/URLtransfer.html”, when the URL of the text file of URLtransfer.html is written in a status before being URL encoded so as to be easily understood, the site accessing unit 20 sets the name of the shopping site and the extracted keyword as parameters in a query string of the URL of the text file of URLtransfer.html so that the URL, for example, is “http://www.URLServer.co.jp/URLtransfer.html? site=laplata.co.jp&program=Journey of Japanese Gourmet”. In the above example, the site accessing unit 20 sets the “laplata.co.jp”, which is the name of the shopping site, in “site=” which is the first query and sets the name of the program “Journey of Japanese Gourmet”, which is a keyword, in “program=” which is a second query.
The site accessing unit 20 finally URL-encodes “http://www.URLServer.co.jp/URLtransfer.html?site=laplata.co. jp&program=Journey of Japanese gourmet” and generates the URL in which the name of the shopping site and the extracted keyword are set as parameters in the query string of the URL of the text file of URLtransfer.html. In other words, the site accessing unit 20 finally generates a URL of “http://www.URLServer.co.jp/URLtransfer.html?site=%3d%83%89%8 3v%83%89%83%5e.co.jp&program=%93%fa%96%7b%83O%83%8b%83%81%82% cc%97%b7”. Therefore, the site accessing unit 20 accesses the text file of URLtransfer.html stored by the storing unit 82 of the acquisition objective information generating device 201 using the generated URL.
In the acquisition objective information generating device 201 which is a main part of the second embodiment, the communicating unit 81 outputs the query string in the URL accessed by the site accessing unit 20 to the generating unit 83. The generating unit 83 analyses the URL to extract the first query and the second query and generates the acquisition objective information for obtaining the information of the webpage related to the keyword extracted by the extracting unit 16 in the shopping site of the name registered by the site name selecting unit 18 of the television broadcast receiving device 101 according to the second embodiment in accordance with the acquisition objective information generating rule stored by the storing unit 82. The communicating unit 81 transmits the acquisition objective information to the television broadcast receiving device 101 through the Internet 500 as the html text which is transited to the acquisition objective information (URL) generated by the generating unit 83. The site accessing unit 20 of the television broadcast receiving device 101, similarly to the first embodiment, receives the acquisition objective information from the acquisition objective information generating device 201 and obtains the information of the webpage related to the keyword extracted by the extracting unit 16 in the shopping site of the name selected and determined by the site name selecting unit 18 using the acquisition objective information.
Hereinafter, the operation when the generating unit 83 generates the acquisition objective information will be described with reference to
First, the generating unit 83 URL-decodes the query string in the URL used when the television broadcast receiving device 101 according to the second embodiment accesses the acquisition objective information generating device 201 (S21). In other words, the generating unit 83 URL-decodes “site=%3d%83%89%83v%83%89%83%5e.co.jp&program=%93%fa%96%7b%83 O%83%8b%83%81%82%cc%97%b7” (S21).
Next, the generating unit 83 extracts an element of the first query string starting with Site= and an element of the second query string starting with program= (S22). In other words, the generating unit 83 extracts “laplata.co.jp” which is the name of the shopping site as an element of the first query string and extracts “Journey of Japanese Gourmet” which is the name of the program which is the keyword as an element of the second query string (S22).
Next, the generating unit 83 generates the acquisition objective information (URL) for obtaining the information of the webpage related to the keyword extracted by the extracting unit 16 in the shopping site of the name selected and determined by the site name selecting unit 18 in accordance with the acquisition objective information generating rule stored by the storing unit 82 (S23). The generating unit 83 may generate the acquisition objective information using an algorithm performed by the generating unit 19 of the first embodiment or may generate the acquisition objective information using other algorithms. The generating unit 83 may generate the acquisition objective information using a CGI program or a servlet having higher degree of freedom as a means of executing the algorithm.
An operation when the generating unit 83 generates the acquisition objective information using an algorithm that is performed by the generating unit 19 according to the first embodiment will be described with reference to
First, the generating unit 83 judges whether the name of the shopping site is “laplata.co.jp” (S31). If it is judged that the name of the shopping site is “laplata.co.jp” (Yes in S31), the generating unit 83 converts <“http://www.laplata.co.jp/s/keywords=”+program name> into SJIS to generate the URL encoded character string as the acquisition objective information (S32).
In step 31, if it is judged that the name of the shopping site is not “laplata.co.jp” (No in S31), the generating unit 83 judges whether the name of the shopping site is “mahoo shopping” (S33). If it is judged that the name of the shopping site is “mahoo shopping” (Yes in S33), the generating unit 83 converts <“http://www.shopping.co.jp/search?P=”+program name> into EUC to generate the URL encoded character string as the acquisition objective information (S34).
In step S33, if it is judged that the name of the shopping site is not “mahoo shopping” (No in S33), the generating unit 83 judges whether the name of the shopping site is “nedan.com” (S35). If it is judged that the name of the shopping site is “nedan.com” (Yes in S35), the generating unit 83 URL encodes <a character string of “http://nedan.com/tv/search/kw=”> to be generated as acquisition objective information (S36).
In step S35, if it is judged that the name of the shopping site is not “nedan.com” (No in S35), the generating unit 83 judges whether the name of the shopping site is “bitter” (S37). If it is judged that the name of the shopping site is “bitter” (Yes in S37), the generating unit 83 URL encodes a character string of <“http://www.bitter.co.jp/dap/sv/list1?keyword=”> to be generated as acquisition objective information (S38).
In step S37, if it is judged that the name of the shopping site is not “bitter” (No in S37), the generating unit 83 generates the acquisition objective information indicating that the name of the shopping site is unclear (S39). See
In step 24 which is the next step of step S23 in
<meta http-equiv=“Refresh” content=“0;URL=acquisition objective information(URL)”> [Equation 1]
Finally, the communicating unit 81 transmits the html text in which Equation 1 is included, that is, the html text in which the acquisition objective information is included to the television broadcast receiving device 101 through the Internet 500. The site accessing unit 20 of the television broadcast receiving device 101 receives the html text in which information which will be transited into the acquisition objective information from the acquisition objective information generating device 201 is included and analyzes the html text to obtain information of the webpage related to the keyword extracted by the extracting unit 16 at the shopping site having the name accepted by the site name selecting unit 18 similarly to the first embodiment. In other words, the site accessing unit 20 operates as a normal html browser. Therefore, the site accessing unit 20 obtains the information of the webpage related to the keyword called “Journey of Japanese Gourmet” at the shopping site called “laplata.co.jp” illustrated in
As described above, in the second embodiment, rather than the television broadcast receiving device 101, the acquisition objective information generating device 201 generates the acquisition objective information. In the second embodiment, it is possible to generate the acquisition objective information using an algorithm having a higher degree of freedom than that in the first embodiment. Further, only the generating unit 83 of the acquisition objective information generating device 201 is changed to change the algorithm to be generated. Furthermore, it is possible to generate the acquisition objective information for obtaining the information of the webpage related to a keyword related to a program which is watched by the user from the shopping site selected by the user without inputting the character by the user.
Also in the above-described second embodiment, the functions of the configuring units of the television broadcast receiving device 101 and the acquisition objective information generating device 201 may be implemented by cooperation of hardware such as a CPU (processor) and a memory of a computer with a computer program that implements the functions. Alternatively, the functions may be implemented by a dedicated circuit or by any forms. A computer program for implementing one or plural functions of all configuring units of the television broadcast receiving device 101 and the acquisition objective information generating device 201 in the second embodiment may be stored in a recording medium.
If information obtained by using the acquisition objective information is a search result of the webpage related to the keyword related to the program which is watched by the user in the shopping site selected by the user, the acquisition objective information may be search result acquisition objective information.
Next, the configuration of a television broadcasting system according to a third embodiment will be described with reference to
As illustrated in
As illustrated in
In the first embodiment, when the acquisition objective information is generated, the generating unit 19 generates the acquisition objective information using the name of one shopping site selected and determined by the site name selecting unit 18 and the keyword extracted by the extracting unit 16. In contrast, in the third embodiment, the generating unit 19 generates the acquisition objective information also using the unique query string which is stored by the identification information storing unit 91. By doing this, it is possible to access the shopping site using the generated acquisition objective information. Further, with respect to the above-mentioned “unique”, every television broadcast receiver may be unique or every model may be unique.
It is assumed that the information for generating the acquisition objective information is the html text which is equivalent to
If there is a html text “character string starting with affiliate=” of
In the html text of
The site accessing unit 20 of the television broadcast receiving device 102 according to the third embodiment accesses a shopping site 600 using the URL generated by the generating unit 19. When the shopping site 600 is accessed, if a character string of “&afid=” is included in the query string, the shopping site 600 recognizes that a specific television broadcast receiving device 102 accesses the shopping site 600, and specifies an accessing source by a character string of “abcd1234” which is next to “&afid”.
Thereafter, if the user does the shopping at the shopping site 600 through the site accessing unit 20 of the television broadcast receiving device 102, the shopping site 600 recognizes a price corresponding to the shopping. The shopping site 600 has a table of bank accounts corresponding to each of the accessing sources. Therefore, the shopping site 600 transfers a predetermined percentage of the prices for the shopping, for example, 3% of the price to a bank account linked to “abcd1234” of a bank site 900 through the Internet 500 as a compensation for introducing the shopping site 600. In other words, the shopping site 600 transfers a predetermined percentage of the prices for the shopping to a bank account of a user of the television broadcast receiving device 102 of the bank site 900 through the Internet 500.
Further, in the third embodiment, the site accessing unit 20 transmits the information that specifies the accessing source by the query string to the shopping site 600 as the individual identification information. However, the site accessing unit 20 may transmit the information that specifies the accessing source, that is, the individual identification information of the television broadcast receiving device 102 to the shopping site 600 by means other than the query string, for example, a User Agent.
Further, in the system according to the second embodiment, the site accessing unit 20 of the television broadcast receiving device 101 may transmit the individual identification information of the television broadcast receiving device 101, that is, information that specifies the accessing source to the shopping site 600. Further, also in the system according to the second embodiment, the shopping site 600 may transfer a predetermined percentage of the prices for the shopping to a bank account of a user of the television broadcast receiving device 101 of the bank site 900 through the Internet 500.
Further, in the above example, an example that uses information in which the query string is inserted in the URL as the information of the accessing source is described. However, the present invention is not limited thereto, but information combining the URL and the User Agent may be used or other information may be used.
As means for transmitting the information to the accessing destination, other communicating means such as Ethernet (registered trade mark) or a cellular phone network may be used.
