Description

  The present invention relates to a digital broadcast receiving apparatus and program for receiving a digital broadcast program and displaying it on a display and displaying hypertext including a hyperlink on the display.

  Due to the rapid spread of the Internet, the number of users who browse WEB pages is increasing. As representatives of WEB pages, there are hypertexts such as HTML texts and HTML contents described in a hypertext markup language (Hyper Text Markup Language). The hypertext markup language is written in text format, and character modification information and layout information can be specified by a code between tags "<" and ">" called tags. It is possible to specify the reproduction of a hyperlink and to describe a hyperlink related to another hypertext. Such “net surfing” is frequently performed to go from the WEB page to the linked WEB page.

  In “surfing the net”, in addition to walking to the linked WEB page, there is also frequent operations such as returning from the linked WEB page to the previous WEB page, and the return destination is the previous WEB page. In some cases, it may be a previous WEB page.

  By the way, devices having a function of connecting to the Internet and displaying a WEB page have spread to home appliances such as PDAs, mobile phones, and television receivers in addition to personal computers.

  In the case of a personal computer, software called a browser is usually installed in the hard disk to connect to the Internet and search and browse the WWW (World Wide Web) server on the Internet. A linked hyperlink in the WEB page can be clicked with the mouse to move from the link source hypertext to the link destination hypertext.

However, unlike a personal computer, an Internet TV receiver has a browser function that is significantly reduced because it requires a minimum amount of memory to reduce costs when the browser function is built-in. Unlike a mouse, which is one of the PC input tools, and a browser for TV (a browser for TV), anchor points (hereinafter referred to as books) on the same page of hypertext displayed on the display by remote control. In the specification, it is called a hyperlink), and the focus corresponding to the cursor on the personal computer is moved one by one or by skipping to switch the hypertext page consisting of multiple pages, or link to another hypertext. To move the hypertext (example If, see Patent Document 1).

If it is not necessary to implement the onload event, it may be omitted. In this case, the onload event generation process is omitted in FIG. 9 in the same manner as the onclick event generation process.

  Then, the browser 105 analyzes the acquired cookie information and determines whether or not the ID of the hyperlink tag in the link destination HTML content 20 to be linked is stored (S907).

  Here, only the ID of the tag of the hyperlink selected in the link source HTML content 10 acquired in step 903 is stored in the current cookie information, and the hyperlink of the link destination HTML content 20 to be linked is stored. Since the tag ID is not stored, the browser 105 determines that the acquired cookie information does not include the ID of the hyperlink tag in the link destination HTML content 20 to be linked (S907 “NO”). For example, as shown in FIG. 8, an initial position dependent on the browser 105, for example, the top hyperlink 810 is focused by a method or the like (S 910), and the linked HTML content 20 is displayed on the display 107 (S 911). . Note that the focus method is a JavaScript described in document.getElementbyID ("ID name"). Focus () in the HTML content, and for an element such as a hyperlink that can be focused by JavaScript. A method that can be focused.

  On the other hand, if the link to the HTML contents 10 and 20 is repeated several times and the ID of the hyperlink tag selected in the link destination HTML content 20 acquired in step 903 is stored, the browser 105 determines that there is an ID of a hyperlink tag in the link destination HTML content 20 to be linked to the acquired cookie information (“YES” in S907), and the hyperlink has an ID tag acquired by the focus method or the like. Is focused (S909), and the linked HTML content 20 is displayed on the display 107 (S911).

  The above processing is the display processing procedure of the link destination HTML content 20 in the first embodiment until the hyperlink is selected in the link source HTML content 10 and the link destination HTML content 20 is displayed.

  Next, when the return button 206 of the remote controller 120 is pressed, etc. until the display returns to the display of the link source HTML content 10 from the link destination HTML content 20 displayed by the processing procedure as shown in FIG.

Note that the return commands include a one-page return command for returning to one page of the link source HTML content displayed on the display 107 and a multi-page return command for returning a plurality of pages continuously.

  Then, the key input detection / analysis unit 108 outputs the return instruction to the browser 105, and the browser 105 receives the return instruction (S1001).

  The browser 105 receives the return instruction, reads the link source HTML content 10 that is the link source of the currently displayed link destination HTML content 20 from the storage unit 106 or the information acquisition unit 104, and performs analysis processing (S1002). When the onload event is generated (S1003), the browser 105 executes the focus irradiation (setting) program 41 to the link source hyperlink of the JavaScript included in the hypertext 40 of the first embodiment shown in FIG. First, cookie information acquisition processing is performed (S1004). The onload event is an event process that occurs when the specified function is executed at the moment when the loading of the HTML content is completed in JavaScript described as <body name"> in the HTML content. is there. If it is not necessary to implement the onload event, it may be omitted. If omitted, the onload event generation process may be omitted in FIG. 10 as in FIG.

  Then, the browser 105 determines whether or not the acquired cookie information includes the ID of the tag of the hyperlink 2 to the link destination HTML content 20 selected in the link source HTML content 10 to be linked, that is, the link source HTML content 10 to be returned. Judgment is made (S1005).

  Here, since the link destination HTML content 20 is an HTML content that has been linked by selecting the hyperlink 2 in the link source HTML content 10, the cookie information acquired in S1004 includes the hypertext stored in S904 shown in FIG. There is ID information of the tag of link 2.

  Therefore, in this case, the browser 105 according to the first embodiment determines that there is ID information of the tag of the hyperlink 2 to the link destination HTML content 20 selected in the link source HTML content 10 in the acquired cookie information. (S1005 “YES”), the ID information of the previously selected and linked hyperlink 2 tag acquired from the cookie information is acquired, and the focus method or the like is applied to the hyperlink 2 that is the previously selected linked source hyperlink. (S1006), and the link source HTML content 10 is displayed (S1008).

  As a result, when the link source HTML content 10 is linked to the link destination HTML content 20, the link source HTML content 10 is focused on the display 107 as shown in FIG. Will be displayed.

  If the ID of the link source hyperlink tag selected in the link source HTML content 10 to be returned to the current cookie information is overwritten or deleted and does not exist, the browser 105 links to the acquired cookie information. It is determined that there is no tag ID of the link source hyperlink in the link source HTML content 10 to be tried (S1005 “NO”), and the focus is set to the initial position depending on the browser 105 by the focus method or the like (S910). The original HTML content 10 is displayed on the display 107 (S1008).

In the digital broadcast receiving apparatus 100, the browser 105 performs the processing shown in FIG. 10 and returns to the state of the HTML document 120 shown in FIG. 13 which is the link source HTML content of the HTML document 140. That is, the display returns to the display of the HTML document 120 that is the link source HTML content in which the hyperlink 122 “view detailed explanation” on the page of the HTML document 120 is focused.

  Note that the browser 105 does not return to the state of the HTML document 120 shown in FIG. 13 by programming the hypertext shown in FIG. 4 so that priority is given to returning to the hyperlink on the right side of the HTML document 120. As shown in FIG. 12, it is of course possible to return to the display state of the HTML document 120 in which the “recording reservation” hyperlink 121 is focused.

  Thus, according to the digital broadcast receiving apparatus 100 of the first embodiment, when a hyperlink is selected in the link source HTML content and the link destination HTML content indicated by the hyperlink is displayed, in the link source HTML content, The ID of the link source hyperlink tag is stored, and when the link source HTML content is displayed from the link destination HTML content to the link source HTML content, the link is made based on the stored link source hyperlink tag ID. Since the focus is placed on the link source hyperlink selected in the original HTML content, the link source HTML content is displayed from the link destination HTML content to the link source HTML content by the page return operation, and the link source When the remote control operation is performed again in the TML content, the focus position is in the previously selected link source hyperlink, so it is not necessary to move the focus from the initial position, such as returning from the link destination HTML content to the link source HTML content again. The burden of remote control operation can be reduced.

  In particular, in the digital broadcast receiving apparatus 100 according to the first embodiment, unlike a mouse such as a personal computer, a remote controller 120 that restricts movement and selection of a focus corresponding to a cursor on the personal computer is used. The difficulty of operation of the browser 105 and the remote controller 120 can be reduced, and convenience can be improved.

Embodiment 4 FIG.
Next, a fourth embodiment will be described. In the first to third embodiments, attention has been paid to returning from the linked hypertext to the link source hypertext by the return command. However, by selecting the hyperlink in the link destination hypertext, the link source hypertext is changed to the link source. Since the case of linking to hypertext is not taken into account, when a hyperlink is linked to the link source hypertext, the focus automatically moves to the initial position even though the return operation is not performed. It can also be a burden. Therefore, the fourth embodiment aims to reduce the operation by returning to an arbitrary focus position.

  Here, the link specifying an arbitrary initial focus position includes a link in which the id attribute by the fragment descriptor and the name attribute of the a tag are described after “#” of the URL, and a character after “?” Attached to the URL. A link using a query string (also called a query string) that describes information in columns and exchanges information between hypertexts is conceivable.

  Since the operation for the fragment descriptor is independently performed by the browser, it can be assumed that the HTML document designer cannot control the operation. Therefore, in the fourth embodiment, it is considered that the query string is used to return to an arbitrary focus position.

  By the way, in the query string, the HTML document designer can acquire the URL using a javaScript API, and can extract the query string from the acquired URL. As a characteristic of the query string, even when the hypertext displayed by the URL with the query string is linked back to another hypertext and returned, the query string remains in the link source hypertext URL. .

  Therefore, when the link source hypertext is displayed by the return operation, when the link source hypertext having the tag ID information storing the focus position is displayed by the hyperlink having the instruction of the initial focus position, It is necessary not to misrecognize the initial focus position.

  Here, in the case of a processing procedure in which a query string is prioritized simply by a URL with a query string, when a link is made from a hypertext of a URL with a query string to another hypertext by a link, it is still selected. The tag ID is stored and linked. However, when returning from the link destination hypertext to the link source hypertext, since the URL still has a query string, it is not the initial focus position based on the selected tag ID information, but the initial focus position based on the query string information. .

  Therefore, in the fourth embodiment, the hypertext linked by the URL with the query string acquires a tag ID that is information indicating the initial focus position from the query string, and the cookie or the like that already stores the acquired tag ID. By overwriting and saving the tag ID storage area in the same format, deleting the query string from the URL with the query string, and reloading the link source hypertext with the URL without the query, the query string remains in the URL Do not become.

  Since the configuration itself of the digital broadcast receiving apparatus is the same as that of the first embodiment shown in FIG. 1, the parts unique to the fourth embodiment will be described with reference to FIG. Here, a link source hypertext in which information indicating an initial focus position to an arbitrary hyperlink is added to a URL as a query string, or a link destination HTML link destination hypertext including a URL of the link source hypertext as a hyperlink May be stored outside this apparatus such as the server 130 on the Internet, or may be stored inside this apparatus such as the storage unit 106. Further, the browser 105 executes a program described later described in these hypertexts, thereby functioning as a query string addition determination unit, an initial focus position information acquisition unit, a display control unit, and the like according to the present invention.

  FIG. 21 shows a state in which the HTML content 220 “Introduction to Usage” is displayed on the display 107 by the browser 105. Here, when the hyperlink 221 named “program” is selected, the hyperlink 223 “view detailed explanation” included in the content 222 named “program guide” is focused. In the figure, the state in which the hyperlink 223 “view detailed explanation” is selected is represented by surrounding the hyperlink 223 with a solid line 224.

  Here, when the hyperlink 223 is selected, for example, as shown in the flowchart of FIG. 9, an onclick event occurs (S902), and the browser 105 displays the hypertext 40 of the first embodiment shown in FIG. The included hyperlink tag ID acquisition and storage program 42 is executed (S903), and the obtained information is stored in the cookie (S904).

  FIG. 22 shows a state in which the hyperlink 223 in FIG. 21 is selected, and the HTML content 230 of the link destination “How to read the program guide” is displayed on the display 107 by the browser 105. Here, the link destination HTML content 230 is provided with a hyperlink 231 named “to begin with” for linking to the link source HTML content 220, and the hyperlink 231 is focused. . In the figure, the state in which the hyperlink 231 is focused is represented by surrounding the hyperlink 231 with a broken line 232.

  Here, the hyperlink 231 with the name “Getting Started” has the HTML content 220 “Getting Started” shown in FIG. 21 as the URL of the link destination and, for example, “ A query string having the “help” hyperlink as the initial focus position is added to the URL. Of course, query strings with “remote control” other than “help”, hyperlinks such as “voice”, “energy saving”, “program”, “recording reservation”, “net”, “all” etc. as the initial focus position You may make it add to the URL. This setting is a tag ID setting program 44 of the HTML content 230 shown in FIG.

  FIG. 23 shows a state in which the hyperlink 231 named “to the usage guide” focused on the HTML content 230 displayed on the display 107 is selected.

  Therefore, in FIG. 23, this state is indicated by surrounding the hyperlink 231 with the name “to the usage guide” by a solid line 240.

  FIG. 24 shows the state of the linked HTML content 220 displayed when the hyperlink 231 in FIG. 23 is selected.

  As described above, the hyperlink 231 with the name “Getting Started” in FIG. 23 has the HTML content 220 “Getting Started” as the link destination URL and the HTML content 220 This is because a query string having the “help” hyperlink 250 in FIG. 5 as an initial focus position is added to the URL of the hyperlink 231.

  Therefore, when the HTML content 220 shown in FIG. 24 is displayed on the display 107 by the browser 105 by selecting the hyperlink 231, the “help” hyperlink 250 is focused. A broken line 251 indicates that the “help” hyperlink 250 is selected and the “help” content 252 is displayed.

  FIG. 25 is a diagram illustrating an example of a data structure of HTML content 220 that is hypertext to be executed by the browser 105 of the digital broadcast receiving apparatus according to the fourth embodiment.

  For example, as shown in FIG. 25, the data structure of the HTML content 220 to be executed by the browser 105 according to the fourth embodiment is a page display processing program 41 of the HTML content 220 and a tag ID acquisition / storage program of the HTML content 220. 42, a tag ID setting of the HTML content 220, and a program reading program 43 when a hyperlink is selected. These programs 41 to 43 are the same as those of the first embodiment shown in FIG.

  In the fourth embodiment, the processing procedure of S3004 to S3008 unique to the fourth embodiment described in FIG. 27, that is, the analysis of the query string in the URL of the HTML content 220, the reload after removing the query string, etc. And a program 45 for executing

  FIG. 26 is a diagram illustrating an example of a data structure of HTML content 230 that is hypertext to be executed by the browser 105 according to the fourth embodiment.

  For example, as shown in FIG. 26, a tag ID setting program 44 of the HTML content 230 is set in the data structure of the HTML content 230 to be executed by the browser 105 of the fourth embodiment.

  Next, a procedure for processing the hypertext storing the tag ID of the selected hyperlink without conflict with the indication of the initial focus position by the query string for the time of being displayed by the return operation is used with reference to FIGS. I will explain.

  FIG. 27 shows the present embodiment for setting the focus to an arbitrary initial focus position specified by the query string in accordance with the instruction of the initial focus position by the query string even when the hyperlink is selected to return to the link source hypertext. 4 is a flowchart showing the processing procedure of FIG.

  In FIG. 27, shaded portions S3004 to S3008 are processing procedures peculiar to the fourth embodiment that are not included in the flowchart of FIG. 9 or FIG.

  That is, when a hyperlink is selected as in S901 in FIG. 9 (S3001) or a command to return as in S1001 in FIG. 10 is received (S3002), the present embodiment is performed in the same manner as in S1002 in FIG. The browser 105 of the form 4 reads and analyzes the link source HTML content (S3003), and determines whether there is a query string in the URL of the hyperlink (S3001) selected by the user or the return instruction (S3002) (S3004). ).

  In the fourth embodiment, it is assumed that the query string is set in the URL of the hyperlink 231 of the HTML content 230 shown in FIG. 23, while the URL of the return command (S3002) does not have the query string. explain.

  That is, in the HTML content 230 shown in FIG. 23, when the hyperlink 231 is selected by the user (S3001), the browser 105 of the fourth embodiment displays the HTML content 220 shown in FIG. Before the onload process (S3009) is executed, the URL of the hyperlink 231 selected by the user is analyzed to check whether there is a query string (S3003).

  In the case of the fourth embodiment, since there is a query string in the URL indicated by the hyperlink 231 (S3004 “YES”), the browser 105 of the fourth embodiment acquires the query string from the URL (S3005). The initial focus position information is acquired from the query string (S3006), and the acquired initial focus position information is stored in the cookie (S3007). Note that the browser 105 discards the ID information (eg, S904 in FIG. 9) stored in the cookie when the hyperlink 223 is selected in the process of S3001.

  Next, the browser 105 of the fourth embodiment links to the HTML content 220 shown in FIG. 24 with a URL without a query string to delete the query string (S3008). Then, the link source HTML content is read again and the processing returns to the analysis processing.

  Here, the URL of the HTML content 220 linked from the HTML content 230 is removed from the Cerry string by the processing of S3008 and the query string is not added (S3004 “NO”), so the processing of S3005 to S3008 is performed. Are skipped, and an onload event generation process is performed in the same manner as S906 in FIG. 9 or S1003 in FIG. 10 (S3009). Since the content performed in the onload process is the same as in the first to third embodiments, the initial focus position is applied to the focus position written in the query string stored in the cookie by the process in S3007. The subsequent processing is the same as S907 in FIG. 9 or S1004 in FIG.

  On the other hand, when the display is returned to the link source HTML content 220 by the return instruction (S3002) instead of the selection of the hyperlink 231 in S3001, the browser 105 of the fourth embodiment analyzes the URL and displays the query string. When the presence or absence is confirmed (S3003), since the query string is not added to the URL of the HTML content 220 indicated by the return instruction in this case (S3004 “NO”) as in the first to third embodiments, for example, FIG. The focus ID information stored in the cookie in step S904 is not lost, and the onload processing in step S3009 performs the same processing as in the first to third embodiments, so that the previous focus position is the same as in the first to third embodiments. It is applied to the hyperlink 223.

  As described above, according to the digital broadcast receiving apparatus of the fourth embodiment, the link source HTML content linked by the URL with the query string acquires the tag ID, which is information indicating the initial focus position, from the query string. The saved tag ID is overwritten and saved in the same format in the saved tag ID storage area, the query string is deleted from the URL with the query string, and reloaded with the URL without the query, the query string remains in the URL Since the link that specifies the initial focus position by the query string can be used, the content creator's intended behavior that aims to reduce the operation or attract the user's attention can be used. Convenience can be improved.
