Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an HTML document, and more particularly to its specification, display control method and apparatus.
[0002]
[Prior art]
An HTML document is a document described in a Hyper Text Markup Language, and has been rapidly spread in recent years because it is used on the Internet's World Wide Web WWW.
[0003]
The HTML document itself is written in a text format. Character modification information, layout information, etc. are specified by a code sandwiched between symbols “<” and “>” called tags, and a program called a browser interprets the tags. The HTML document is displayed.
[0004]
An HTML document can insert other text, images, and sounds into the document. In addition, each part of a certain HTML document can be linked to an image or another HTML document. That is, in an HTML document, a certain position (anchor point or hot spot described later) in the same document is linked (related) to another position, another file, or the like, so that the position can be immediately changed to a linked position. It is possible to move and browse extremely efficient and various documents (including so-called multimedia). Further, a window for sending an e-mail can be opened based on the selection of the anchor point.
[0005]
[Problems to be solved by the invention]
As described above, by setting various anchor points in the HTML document, if the user selects the anchor point in the displayed HTML document when viewing it with a browser, the anchor point is set. You can move to the linked position and activate the corresponding function.
[0006]
Instructing and selecting an anchor point can be usually performed by directly pointing an instruction index (for example, a mouse cursor) on a display screen using a pointing device such as a mouse in a personal computer. However, since the mouse cannot normally be used on Internet televisions and the like that have become widespread in recent years, a plurality of anchor points included in the HTML document are designated in order using a movement key or the like on the remote controller. Note that the browser can recognize the position of the anchor point, and the anchor point designation based on the movement key designates the anchor point one by one only by instructing the movement in the forward direction or the reverse direction. . This specification of the anchor point is referred to as focus in this specification. The position of the anchor point that is focused in the currently displayed HTML document is also referred to as a focus position.
[0007]
In such a method of specifying an anchor point using a movement key, when there are many anchor points from the currently focused anchor point to the target anchor point, the focus is sequentially changed by continuously pressing the movement key in one direction. You have to wait until you reach the desired anchor point. Even if this time is several seconds, it is a long time for the user. In particular, if the user is connected to the Internet, the call charge and the connection charge are affected.
[0008]
Further, even when there are many anchor points with low selection frequencies, the movement key has the inconvenience that the focus position must be sequentially moved through all such anchor points.
[0009]
The present invention has been made in view of such a problem, and an object thereof is to provide an HTML document display control method and display device capable of skipping a specific anchor point when a focus movement instruction is given to the anchor point. And
[0010]
[Means for Solving the Problems]
The present invention In the display device A display control method for displaying an HTML document on a display screen, Receiving a user instruction; focusing one of a plurality of anchor points included in the HTML document; and, in response to the user instruction, out of the plurality of anchor points included in the HTML document, the focused anchor. Checking the attribute added to the next anchor point of the point, and when the attribute added to the next anchor point is an attribute that skips focus, For the anchor point, skip step without focusing, When the attribute added to the next anchor point is not an attribute for skipping focus, the step of moving the focus for the anchor point; It is characterized by having.
[0011]
The first and second instructions can be performed by a user operating a first instruction means such as a key or a switch.
[0012]
Preferably, when a focus movement is instructed by a second instruction means different from the first instruction means for performing the first and second instructions, an attribute for skipping the focus is added. Even for the anchor point, the focus is sequentially moved with respect to each anchor point.
[0013]
According to another aspect of the present invention, there is provided a display device for displaying an HTML document on a display screen, the display having the display screen, an interpretation means for interpreting the HTML document, and an interpretation by the interpretation means. As a result, display content determination means for determining the display content to be displayed on the display, display memory for storing the display content determined by the display content determination means, and display control for displaying the content of the display memory on the display Means and an anchor point sequential instruction for selectively generating a first instruction for sequentially moving the focus in the forward direction and a second instruction for sequentially moving in the reverse direction with respect to a plurality of anchor points included in the HTML document. And the display memo to sequentially move the focus with respect to each anchor point according to the first instruction or the second instruction. Focus moving means for changing the display content stored in the first and second focus moving means when moving the focus in response to the first or second instruction. In response to an instruction, an anchor point to which an attribute for skipping focus is added is skipped without focusing.
[0014]
Changing the display contents by the focus moving means includes changing the display color of the anchor point, display attributes such as underline, and if the target anchor point is outside the display screen, the document part should include the anchor point. Including updating the display content to display on the screen.
[0015]
In this apparatus, it is preferable that the apparatus further includes a second instruction unit that is different from the anchor point sequential instruction unit, and the focus moving unit is configured to perform the operation even if the anchor point has an attribute for skipping the focus. When instructed by the second instruction means, focus skip is not performed. According to the second instruction means, an arbitrary anchor point can be selected without skipping any anchor point. When the attribute for skipping focus is added to the target anchor point, the first and second indicating means are used together, and after the focus is moved to the vicinity of the target anchor point by the first indicating means, the first It is also possible to switch the operation to the two instruction means so as to reach the target anchor point.
[0016]
The display control method according to the present invention can be realized by a computer program. Therefore, when displaying the HTML document on the display screen, in accordance with the first instruction from the user, the step of sequentially moving the focus forward with respect to the plurality of anchor points included in the HTML document; In response to the second instruction, the step of sequentially moving the focus in the reverse direction to a plurality of anchor points included in the HTML document, and the first and second when moving the focus A recording medium recording a computer program for executing the step of skipping without focusing for an anchor point to which an attribute for skipping focus is added is included in the scope of the present invention. The recording medium is not limited to a portable recording medium such as a semiconductor ROM, a CD-ROM, or a floppy disk, but also includes a non-portable recording medium such as a hard disk.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the drawings.
[0018]
First, as a prerequisite for understanding the present invention, the Internet and the structure of an HTML document will be described.
[0019]
Distribution of HTML documents on the Internet is performed by a computer on the Internet called a WWW server. A user can access a document on the Internet using browsing software called a WWW browser (also referred to as a web browser) on a client computer (also simply referred to as a client). In order to connect a client computer to the Internet, in general, an individual or the like connects through a service organization called a service provider by dial-up connection via a public line. There are cases where dedicated communication lines are used in universities, research institutes, and companies. By connecting the client computer to the Internet, necessary information (including text, images, sounds, etc.) can be obtained from all over the world while staying at home.
[0020]
The unit of information to be accessed is a file on the WWW server called a page. By setting a link to be described later, the user can browse and browse from one page to another page one after another. . The length of the page is not constant and can be freely changed by the creator of the page.
[0021]
A specific address (homepage) on the WWW is assigned a unique address on the Internet called a URL (Uniform Resource Locator).
[0022]
The structure of the URL consists of a protocol name, a server name, and an item path name as shown below.
[0023]
http: // www. abc. or. jp / def / ghi. html
The protocol name indicates how the computer interprets the information. Since the WWW server and the web browser exchange information by a method called HTTP (Hyper Text Transfer Protocol), the protocol name at the top of the URL is “http:”. In addition, there is a protocol called ftp for file transfer. “Www.abc.or.jp” represents a server name. “Www” indicates that the server is a WWW server. In “abc.or.jp”, “abc” indicates an organization name, “or” indicates an organization type (in this case, various organizations / individuals), and “jp” indicates a code indicating a country (in this case, Japan). . The item path name “def / ghi.html” following the server name indicates the location of the item on the server. The path name usually indicates the name of a file constituting the page. In “def / ghi.html”, “def” is a directory name, “ghi” is a file name, and “html” is an extension indicating that this file is an HTML file.
[0024]
Next, the configuration of an HTML file (HTML document) will be described. In this specification, a document described in the HTML language is called an HTML document, and the file is called an HTML file (or HTML text).
[0025]
FIG. 4 shows the basic structure of an HTML document. An HTML document is substantially a text file, but has embedded codes (represented by symbols “<” and “>”) scattered throughout the page. Normally, the specified range is sandwiched between a pair of start and end tags. The end tag has a “/” to distinguish it from the start tag. However, it may be used alone, such as <P> representing a paragraph break or <BR> representing a line break. With this tag, in addition to character modification information and layout information, link information can be set. The browser interprets the tag, displays the HTML document on the screen in a format according to the creator's intention, and controls the link.
[0026]
As shown in FIG. 4A, the basic structure of an HTML document is a mixture of various tags in a text document. When the HTML document is interpreted by the browser and displayed on the screen, the tag is not displayed as shown in FIG. 4B, and only the contents of the instruction are reflected in the display. When the user selects a specific character string in the HTML document, the function of jumping to another page related to the character string is called a link. The location 201 in the page of the HTML document “aaa.html” in FIG.
<A HREF="bbb.html"> BBB </A>
It is described. A tag used for setting a link is called an anchor tag (<A... </A>), and a portion sandwiched between the anchor tags is called an anchor point or a hot point. Anchor tag start tag “HREF =” in <A HREF=“bbb.html”> indicates link destination access information (file name here). The anchor tag portion is displayed with the character string “BBB” highlighted on the browser screen as the display character string 203 in FIG. This highlighting is performed by changing the color of other character strings or adding an underline. Thereby, when the user selects this character string, it is recognized that the user can move to another page.
[0027]
A location 202 shows a case where an inline image is used as an anchor point. Here, an image file “ggg.gif” is displayed as an image 204 on the screen, and when this image 204 is selected by the user, The contents of the link destination “ccc.html” are read and displayed. Here, an inline image is an image that is embedded and displayed in a page of an HTML document.
[0028]
There are several patterns of link destination access information.
[0029]
As shown in FIG. 5, when a link is set to another page (HTML file) in the same server (host) (also called a link), the file name (which may include a directory name) is the link destination. It becomes the information which shows. FIG. 5A shows the relationship between the link source HTML file and the link destination HTML file. FIG. 5B shows the display contents of the corresponding browser screen. In this example, when the character string “BBB” of the anchor point is selected, a linked HTML file “bbb.html” representing another page is requested, and its contents are displayed.
[0030]
As shown in FIG. 6, there is a case where a link is made to another position in the same page. In such a case, the item name at that position is used as information indicating the link destination. As shown in FIG. 6 (a), here, at the link source <A HREF="#aaa"> AAA </A> indicates the location of the link destination, while <A NAME="aaa"> AAA The description of </A> indicates that a link is made to the item name “aaa”. As can be seen from FIG. 6B, when the user selects the highlighted character string “AAA” on the corresponding browser screen, it is displayed at the position of the item “AAA” at the subsequent position on the same page. Fly. This is normally effective when only a list of items is listed first when one page is long, and a link is made to the corresponding position of each item.
[0031]
FIG. 7 shows the case of linking to a specific position on another page in the same server. In this case, the link destination access information is a combination of the file name of the other page and the item name in the document. In this example, an example of jumping to an item “ppp” of another file “bbb.html” in the same server is shown. FIG. 7A shows the relationship between the link source and link destination HTML files, and FIG. 7B shows the corresponding browser screen.
[0032]
In addition, although not shown, a special command can be described in the start tag portion, and when the anchor point is selected, a script (program) corresponding to the command can be called and executed.
[0033]
Next, FIG. 1 shows a hardware configuration example of an apparatus for realizing the present embodiment. Here, a television with a built-in Internet connection function is assumed. However, the display device is not limited to the television as long as it has an instruction unit that sequentially indicates anchor points (that is, moves the focus with respect to the anchor points).
[0034]
In the configuration of FIG. 1, a central processing unit (CPU) 101 is connected to a bus 100 and controls the entire apparatus of FIG. 1 via the bus 100. The CPU 101 has a calendar / clock function for outputting the current date and time based on a clock oscillator (not shown). The mask ROM 105 stores various computer programs executed by the CPU 101 and necessary data. The font ROM 106 stores font data used on the television screen. The flash memory 107 is a rewritable nonvolatile memory for storing a URL and personal management information (PIM) that the user wants to store in a nonvolatile manner. A program that can be upgraded can also be stored in the flash memory 107. Instead of or in addition to the flash memory, a secondary storage device that is a nonvolatile storage means such as an MD (mini disk) or a hard disk may be adopted. The RAM 108 provides a temporary storage area, a work area, and an area for storing various parameters necessary for executing the program, which are necessary for the CPU 101 to execute the program.
[0035]
Connection to the public line is made via a line terminal (LINE). The line terminal is connected to the bus 100 via the modem 118 and the serial controller 117. When using an ISDN line, although not shown, a DSU (Data Service Unit) and TA (Terminal Adapter) are used.
[0036]
When this apparatus displays the page information received from the public line on the display 122, the display content is once drawn on the display memory (VRAM) 111 via the display controller 110. The contents of the display memory 111 are input to the switching circuit 124 via the digital analog (D / A) converter 112. The display contents can be changed by rewriting the contents of the display memory 111. However, when a so-called color palette (not shown) is used, the display color can be changed by changing the contents of the palette. The change of the display contents in this specification includes the case where the display result is changed by a process other than the rewriting of the contents of the display memory 111.
[0037]
In some cases, the page information includes voice information, and in the case of enabling voice correspondence, an audio controller 114 and a digital analog (D / A) converter 115 are provided, from which a voice signal is output, and a switching circuit 124 is input.
[0038]
The TV circuit 121 extracts and demodulates the video signal and audio signal of each channel selected from the broadcast radio wave received from the antenna 120, and outputs it to the switching circuit 124.
[0039]
The switching circuit 124 switches the signal from the TV circuit 121 and the signal from the D / A converter 112 under the control of the CPU 101, and outputs them to the display 122 and the speaker (SP) 123. By this switching circuit 124, a plurality of divided screens and window screens can be displayed on the television screen.
[0040]
The user uses the remote control 102 to control this device. A signal (for example, an infrared signal) generated from the remote controller 102 is received by the receiver 103, and the signal is decoded by the CPU 101. The remote control 102 is shared with normal television operations. The TV operation signal is transferred to the CPU 101 via the TV controller 104.
[0041]
In the apparatus of FIG. 1, the apparatus configuration for the Internet and the apparatus configuration for the television are controlled by the common CPU 101, but may be controlled by separate CPUs.
[0042]
FIG. 2 shows a configuration example of the remote controller 102.
[0043]
On the upper side of the remote controller 102 is a group of switch buttons 40 for normal television operation, on which a power button, a video / TV button, a numeric channel button 58 and the like are arranged. In the middle part of the remote control 102, there is a switch button group 41 for the Internet, which includes a scroll up button 42, a scroll down button 43, a movement key 44, a selection button 45, a stop button 46, a return button 47, and a advance button. 48, URL button 49, menu button 50, and the like. As the movement key 44, anchor point sequential instruction means is configured. Here, the movement key 44 is circular and has a structure that tilts in four directions, up, down, left, and right. However, the movement key 44 may be composed of separate keys. There is a cover (not shown) at the bottom of the remote controller 102, and when this is opened, buttons for television adjustment that are not normally used are arranged.
[0044]
In order to instruct the user to connect to the Internet using the apparatus shown in FIG. 1, for example, the user presses the menu button 50 shown in FIG. Thereby, the CPU 101 activates the web browser and performs dial-up connection to the provider. Next, a menu screen or window (not shown) including various menu items is displayed on the television screen, for example. The viewer can browse a desired page by selecting menu items from the menu screen.
[0045]
Assume that there is a description part including four anchor tags 71a to 74a as shown in FIG. The former two anchor points of the anchor tags 71a to 74a are character strings, and the latter two anchor points are images, and different HTML files 1st.html, 2nd.html, 3rd.html, and 4th.html are linked respectively. It is specified as the destination. In addition, a character string “KEYSKIP” is added to the anchor tags 71a and 73a at the end of the start anchor tag. This is added in order to expand the function of HTML in this embodiment. The character string is not limited to “KEYSKIP”, and an arbitrary character string can be selected. In the browser, when this character string is found in the start anchor tag, the browser program is extended to skip the anchor point when the focus key is moved by the movement key 44. Note that in a browser that does not support the “KEYSKIP” attribute, the character string “KEYSKIP” is ignored, and the browser operation is not affected at all.
[0046]
The HTML document in FIG. 8A looks like FIG. 8B on the browser screen. Assume that the anchor point 72b is focused (that is, highlighted by a change in display attribute due to color change, inversion, etc.). When there is no description of “KEYSKIP”, when the movement key 44 is operated downward or rightward as usual, the focus moves sequentially from the anchor point 72b to 73b, 74b in the order of description of the HTML text. This process is executed by changing the display content stored in the display memory 111 in the present embodiment by the focus moving means (CPU 101, browser, display controller 110, etc.).
[0047]
However, when there is an anchor point to which the “KEYSKIP” attribute is added as shown in FIG. 8A, the focus moving means skips the anchor point without focusing when the focus is moved by the movement key 44. In the example of FIG. 8B, when the focus moves in the forward direction from the anchor point 72b, the anchor point 73b is skipped and the focus moves to the anchor point 74b. When the movement key 44 is operated upward or leftward, the anchor point 71b to which the “KEYSKIP” attribute is added is skipped.
[0048]
When one of the anchor points is focused and the selection button 45 is pressed, the anchor point is moved to the link destination.
[0049]
Thus, the user cannot select the anchor point to which the “KEYSKIP” attribute is added by the movement key 44. In order to select an anchor point to which the “KEYSKIP” attribute is added, it is preferable to provide a second anchor point sequential instruction means that is different from the movement key 44. The “second anchor point sequential instruction means” may be an independent movement key different from the movement key 44 or an auxiliary key such as a shift key that can be operated simultaneously with the movement key 44. It may be a key. In the case of an independent movement key, it may be provided at a position where it appears when the cover of the remote controller 102 is opened. Alternatively, the function of the movement key 44 may be switched in software according to a user instruction.
[0050]
FIG. 14 shows a flowchart of the focus movement process executed by the CPU 101 (FIG. 1) in response to a focus sequential movement instruction in the browser corresponding to the “KEYSKIP” attribute of the present invention. When an instruction for sequentially moving the focus is received from the movement key 44 or the like, first, it is confirmed whether the instruction is “forward direction (F)” or “reverse direction (B)” (S141). In the case of the movement key 44, the instructions in the right and down directions correspond to “forward direction”, and the instructions in the left and up directions correspond to “reverse direction”. In the case of the rotatable push switch 51, the downward rotation corresponds to the “forward direction”, and the upward rotation corresponds to the “reverse direction”. If it is “forward direction”, an anchor point immediately after the currently focused anchor point is searched for in the HTML document (S142). If it is “reverse direction”, an anchor point immediately before the currently focused anchor point is searched for in the HTML document (S143). When the corresponding anchor point is not found (S144, No), the process proceeds to step S146. When the corresponding anchor point is found (S144, Yes), it is checked whether or not the “KEYSKIP” attribute is added to the anchor point (S145). If it has been added, the process returns to step S141 to search for the next anchor point. If not added, the focus is moved to the anchor point (S146). If the corresponding anchor point does not exist in the previous step S144, the focus of the current anchor point is continued (S146).
[0051]
FIG. 3 shows the appearance of another configuration example of the remote controller 102 suitable for the present embodiment. The remote control 102 has a rotatable push switch 51. The switch 51 has a disc-shaped portion that is 360 ° endless and can be rotated up and down in the R direction, and the rotation of the disc-shaped portion at a predetermined angle is detected together with the rotation direction. In addition, the disc-shaped portion also functions as a push-type switch that can be pressed in the horizontal H direction. Since the configuration and function of such a rotatable push switch 51 itself are known, they will not be described in detail here. In this embodiment, the focus of the anchor point is moved by rotating the switch 51, and the anchor point is selected by pressing the switch 51. In the movement of the focus, as described above, the anchor point to which the “KEYSKIP” attribute is added is skipped. On the other hand, when the operation is performed with the movement key 44, the focus is moved including the anchor point to which the “KEYSKIP” attribute is added. The selection button 45 overlaps with the selection function of the switch 51 and may be deleted. However, the selection button 45 is left in the example of FIG.
[0052]
Next, FIG. 9 illustrates an actual example in which the present invention is applied to personal information management (PIM). FIG. 9 shows a list of personal information including a name, a telephone number, a FAX number, and an e-mail address. This list is described using HTML table related tags. Various convenient functions are realized by setting an anchor point for each item in the list. For example, by setting an anchor point for a name, when a name is selected, detailed information about the person represented by that name is displayed, or by setting an anchor point for an email address, each email address is selected Or a window (or window) for creating an e-mail for the e-mail address can be displayed. When the FAX function is incorporated in the apparatus, a FAX transmission screen (or window) for the FAX number can be displayed by selecting the FAX number. For this purpose, an anchor point corresponding to the FAX number is set.
[0053]
In this example, the “KEYSKIP” attribute is added to the start tag of the anchor point of an item other than the e-mail address. In this way, when there is a focus movement instruction for the anchor point by the movement key 44 (FIG. 2) or the rotatable push switch 51 (FIG. 3), the focus for the anchor point other than the email address is skipped. However, the focus can be moved only to the e-mail address. Therefore, the target e-mail address can be quickly reached in accordance with the instruction for sequentially moving the focus.
[0054]
The example of FIG. 9 shows a state in which the email address “Hikari Ishida” is focused. In FIG. 9, for the sake of convenience, it is designated in bold, but in practice, any highlighting can be used.
[0055]
FIG. 10 shows a part of the HTML document corresponding to FIG. Descriptions 91, 92, 93, and 94 correspond to the name, telephone number, FAX number, and e-mail address in the first line of the list in FIG.
[0056]
The name description 91 specifies the position #AndoYuko of the file contact.html as a link destination. When this anchor point is selected, a window 1100 showing details of personal information as shown in FIG. 11 is displayed. When the return button 47 is pressed, the list display of FIG. 9 is restored.
[0057]
The FAX number description 93 includes a special command (also referred to as a scheme) “faxto:...” For displaying a window 1200 for FAX transmission for the specified FAX number. In response to the selection of the anchor point by the user, the browser calls a script (program module) corresponding to this command with the designated FAX number as an argument. By executing this script, a window 1200 for FAX transmission is opened and predetermined processing is performed.
[0058]
FIG. 12 shows a window 1200 that is opened when this anchor point is selected. In the subject area 1201 in the window 1200, the user can input a character string representing the subject using the software keyboard 1204. A corresponding FAX number is automatically input in the destination area 1202. In the caller area 1203, a user name registered in advance is automatically input. In the body area 1204, the user can input an arbitrary sentence using the software keyboard 1205. When the description of the necessary area is completed and the user selects the send button 1206, the subject and the content of the text are transmitted to the destination FAX machine. If the cancel button 1207 is selected before the transmission button is pressed, the written contents are erased and re-input is possible. When the return button 47 is pressed, the display returns to the list display of FIG.
[0059]
The e-mail address description 94 includes “mailto:...” As a command for opening the e-mail transmission window 1300. FIG. 13 shows an example of this e-mail transmission window 1300. This window 1300 is similar to the FAX transmission window 1200 shown in FIG. 12 except that an e-mail address is automatically set instead of a FAX number as a destination, and an e-mail instead of a FAX is selected by selecting a send button. It is different from the point that is transmitted.
[0060]
Whether to set an anchor point to which item and whether or not to add a “KEYSKIP” attribute to the anchor point is specified in advance in a personal information management program (not shown), or personal information The user can select when registering.
[0061]
Although the present invention has been applied to personal information management as described above, the application of the present invention is not limited to this. For example, for various anchor points in an HTML document of a homepage registered in a WWW server, The “KEYSKIP” attribute can be set for a specific anchor point for its usage frequency, operational convenience, and the like.
[0062]
Further, although the present invention has been described in relation to the Internet, the present invention is not necessarily limited to the Internet, and can be provided for any application using an HTML document.
[0063]
【The invention's effect】
According to the present invention, by providing an anchor point skip attribute, a specific anchor point can be quickly selected even when an operation means for sequentially specifying anchor points in an HTML document is used. Improves.
