Are distinguished. And, generally, when this hotspot is clicked by the mouse connected to the main body, the HTML specified by the HREF attribute is set.
The document is acquired from the WWW server, and the acquired HTML
The display contents are switched based on the document. The same result can be obtained by inputting the HREF attribute value from the keyboard instead of clicking with the mouse.

It should be noted that HTML (Hyper Text)
For Markup Language), see “HT
ML Introduction-WWW Page Creation and Disclosure, by Laura Limay, Prentice Hall Publishing Co., Ltd., April 5, 1996, etc. "and so further explanation is omitted. An example of the display based on the HTML document shown in FIG. 2 is shown in FIG. Character strings 313a, 314a, and 315a that are underlined in the figure are hotspots. Depending on the type of browser to be processed, a target character string may be highlighted or displayed in red or blue to represent a hot spot.

The control information transmitting section 115 has a control information extracting section 115a and a control information transmitting section 115b. The control information extraction unit 115a records the extracted information storage unit 400 as shown in FIG. 4, a tag table (not shown) in which the control contents of HTML tags are associated with each tag, and a character size for display by use. Character size table not shown,
A storage area (not shown) serving as a work area for detecting the display position of the hot spot is provided. In the present embodiment,
In the character size table, “40 × 40” is set as the size of the characters in the title, and the size of the other characters is set as
It is assumed that “20 × 20” is recorded. The work area is a tag storage area for securing a character string sandwiched between <> in a tag, a character string storage area for securing a character string other than the tag, and for controlling detection of a display position. A flag storage area, which is an area for setting a flag, and a register (X, Y) for storing a horizontal position X and a vertical position Y of the display position.

When the HTML document in the control information storage unit 113 is updated, the control information extraction unit 115a updates the HT after the update.
From the ML document, locations described by <A ...> to </A> (hereinafter also referred to as “A tag character string”) are extracted, and in the extraction order, the extraction information storage area 42 of the extraction information storage unit 400.
Stored in 0, and when storage is completed, for each extracted
The approximate display position when the character string to be the hot spot is displayed on the display unit 114 is detected and added to the attribute of the A tag character string.

The control information extracting unit 115a first reads the characters one by one from the first character of the HTML document in the control information storage unit 113, and stops the process when "/ HTML" appears in the character string of the read characters. . Until then, when the character string "<A" appears, the HT of the character string "<A"
The description position in the ML document is stored, the description position of the character string "</A>" that appears subsequently is stored in the HTML document, and the part described by <A ...> to </A> (A tag character string) Is extracted and stored in the extracted information storage area 420 of the extracted information storage unit 400.

When the extraction of the A tag character string is completed, the control information extraction unit 115a reads the tags in order from the beginning of the HTM document stored in the control information storage unit 113, and collates the read tags with the tag table. And interpret the control contents of the tag. To interpret the control content, write the character string following the tag start character one character at a time until the tag end character ">" appears in the tag storage area of the work area. In principle, work is performed when the tag end character appears. The character string written in the area, that is, the character string sandwiched between “<” and “>” is collated with the tag table.

When the control information extraction unit 115a reads the tag, it first sets a flag indicating the interpretation result in the flag storage area of the work area and associates the flag with the tag <> and the corresponding tag <>. The character string sandwiched between /> is secured in the character string storage area of the work area. The method of securing the character string sandwiched between the corresponding tags in the character string storage area is the same as that of the character string in the tag. Next, referring to the character size in the character size table from the secured character string, the head display position in the processing of the next tag is calculated and stored in the register. At this time, if the tag <A> is being processed, the value before updating the register, that is, the display of the first character of the character string (hot spot) secured in the character string storage area of the work area at that time is displayed. The position is inserted and stored at a predetermined position of the corresponding A tag character string that is already stored in the extracted information storage area 420 of the extracted information storage unit 400. The predetermined position is between "<A" and ">" of the attributes of the A tag character string, that is, """on the trailing end side of the two""" indicating the range of the HREF attribute value and the subsequent "". Indicates between ">". At the time of insertion, "," is put between the X-coordinate value and the Y-coordinate value of the display position to delimit it, and both sides are surrounded by (), and one space is left between the HREF attribute value. If the tag <> is not a character string but another tag <(another character string)>, only the flag corresponding to the previous tag <> is set in the flag storage area. , And performs processing according to the next tag <(another character string)>.

The above processing of the control information extraction unit 115a will be described using a specific example. In this embodiment, the size of the display screen is 640 × 480, the head display position of each row is X = 10, and the head row display position of each display screen is Y = 10. The control information extraction unit 115a first reads each character from the first character of the HTML document 200 in the control information storage unit 113, detects a character string "<A" in the character string formed by the read characters, and detects the detected character. The description position in the HTML document of the column “<A” is stored.
In this example, first, “<A” in line 217 is detected, and the description position in the HTML document of the character string “<A” is stored. The character string "</ A
">" Is stored in the HTML document, and "<A
HREF = "http: //www.○○.co.j
p ″> ○○ homepage </A> ”is extracted and stored in the location corresponding to the storage number 1 of the extraction information storage area 420 of the extraction information storage unit 400. The same processing as above is repeated to extract the A tag character strings existing in the rows 219 and 221 and in the order of extraction, the extraction information storage unit 400.
Stored in the extracted information storage area 420.

Subsequently, the control information extraction unit 115a sets the value of the register to (10, 10), and the tag <of line 211 <
HTML> is read. The read character string "HTML" in the tag <HTML> is secured in the tag storage area in the work area, interpreted by referring to the tag table, and the document processing flag is set in the flag storage area in the work area. The document processing flag indicates that the document following the tag is described in the HTML language.

Next, the control information extraction unit 115a determines the line 2
Read the 12 tags <HEAD> and read the tags <
The character string “HEAD” in HEAD> is secured in the tag storage area in the work area, and is interpreted by referring to the tag table,
A head flag is set in a flag storage area in the work area.
The head flag indicates that the HTML document heading follows the tag.

Next, the control information extraction unit 115a determines the line 2
13 tags <TITLE> are read and tags <TITL>
E> is interpreted by referring to the tag table, and a title flag is set in the flag storage area in the work area. The title flag indicates that the character string following the tag is a title. The control information extraction unit 115a subsequently writes the character string following the tag <TITLE> character by character into the character string storage area until the tag </ TITLE> appears, and as a result, the character string “data diagram of operation information "Example" and read the tag </ T
When ITLE> appears, the character size table is referenced to calculate the head display position in the processing of the next tag and store it in the register. Specifically, in the character size table, "40 x
40 "is shown, so the register values (10, 1
To the X value of (0), a value 440 obtained by multiplying the number of characters 11 of the character string “example of data diagram of operation information” by 40 is added, and (450, 1
0).

Next, the control information extraction unit 115a starts a new line because the processing corresponding to the tag <TITLE> is completed. Since the character size of the title is 40 × 40, the top display position after line feed is (10, 50). Then, the title flag set in the work area is reset.
The control information extraction unit 115a uses the tag </ HEA on line 214
D> is read, the read tag </ HEAD> is interpreted by referring to the tag table, it is determined that the heading has been completed, and the head flag set in the work area is reset.

Next, the control information extraction unit 115a determines the line 2
15 tags <BODY> are read and tags <BODY>
Is interpreted by referring to the tag table, and a body flag is set in the flag storage area in the work area. The body flag indicates that the character string following the tag is the body, and character strings not sandwiched by tags of the same type are displayed in the order in which they are described in principle.

The control information extraction unit 115a then continues to line 2
While writing 16 character strings to the character string storage area character by character, as a result, the character string "as the first hot spot" is read, and when the tag <BR> appears, the writing operation is terminated and the character size The head display position in the processing of the next tag is calculated with reference to the table and stored in the register. Specifically, in the character size table,
Since “20 × 20” is shown as the size of characters other than the title, the X value of the register value (10, 50) is first set to the character string “as the first hotspot”.
Add the value 300 multiplied by 20 to the number of characters of 15
0, 50). Next, since the tag <BR> means a line break, the character size other than the title is 20 × 20, and the head display position after the line break is (10, 70).

Then, the control information extraction unit 115a determines the line 2
17 tags <A HREF = "http: // www.
○○. co. jp ″> is read, written in the tag storage area, interpreted according to the tag table, and a hotspot flag is set in the flag storage area in the work area. The hotspot flag indicates that the character string following the tag is a hotspot. The control information extraction unit 115a continues to display the tag <A HREF until the tag </A> appears.
= “Http: //www.○○.co.jp”>, writing the character string following the character string one character at a time to the character string storage area, as a result, read the character string “○○ 's home page”, and tag </ A When> appears, before calculating the top display position in the processing of the next tag, the register value at that time (10, 70), that is, the top character of the character string "Home page of XX" that is a hot spot is displayed. Display position,
The A tag character string stored in the extraction information storage area 420 with the storage number 1 of the extraction information storage unit 400 is inserted into the above-mentioned predetermined position. Next, referring to the character size table, the head display position in the processing of the next tag is calculated and stored in the register. Specifically, in the character size table, “2
0x20 "is shown, the register value (10,
70) is added to the X value, and the value 180 obtained by multiplying the number of characters 9 in the character string "Home page of XX" by 20 is added (190, 70)
Becomes

Thereafter, in the same manner, the processing of lines 218 to 223 is performed to detect the display position of the character string that becomes the hot spot and store it in the corresponding extraction information storage area 420 of the extraction information storage unit 400. Storing is performed by inserting it into the existing A tag character string. Note that the above processing is performed by the tag </ HTML>
Ends when is read. FIG. 4 shows the storage state of the extraction information storage unit 400 when the above processing is completed.

The control information sending section 115b reads the extracted information stored in the extracted information storage section 400 for each storage number unit, associates it with the storage number, and associates it with the storage number.

Therefore, from the main body 110 to the remote control device 1
This has the effect of reducing the transmission load on 50.

Further, according to the remote control system of this embodiment, the display / input unit 156 of the remote control device 150 is provided.
Since the display screen of 1 is constructed on the side of the remote control device based on the extraction information transmitted from the main body 110, there are cases where the creation of the display screen of the display / input unit 156 does not depend on the main body side. Furthermore, according to the remote control system of this embodiment, the HRE transmitted from the main body 110 is transmitted.
The F attribute value (included in the extraction information) is once fetched in the remote control device 150, and the HREF attribute value fetched is
Since the selected HREF attribute value is transmitted to the main body 110 and the display screen of the main body 110 is switched, the remote control device 150 which has taken in the HREF attribute value is not only for the main body of the transmission source but also for other sources. There is an advantage that it can be used for the main body of the device. For example, using this system at work, etc., take only the remote control device that has captured the HREF attribute value back home, and use that remote control device,
You can operate the main unit at home. This eliminates the need to take a note of the HREF attribute value. In addition, HRE, which is generally a long description,
When the F attribute value is input from the keyboard, an input error may occur and the user may be forced to input the value again. However, such a situation can be avoided and the operability may be improved.

Further, the remote control device side controls the display / display.
Since the display data to be displayed on the input unit is generated, it is possible to create a screen according to the display capability of the remote control device. As described above, the present invention has been described based on the embodiments, but it is needless to say that the present invention is not limited to the above embodiments. That is, the following configuration may be adopted. (1) In the present embodiment, the main body to the remote control device is
As the extraction information, the HREF attribute value, the hotspot character string, and the display position information of the hotspot on the main body are transmitted, but only the HREF attribute value and the hotspot character string may be sent. In this case, the hotspot string is
Depending on the storage order of the operation information storage unit, it is displayed at a predetermined position of the display / input unit. An example of the display on the display / input unit in this case is shown in FIG. (2) Further, as the extraction information transmitted from the main body to the remote control device, only the HREF attribute value may be used. In this case, instead of the display / input unit, a display unit using a liquid crystal display or the like is used, and the remote control device 150 is provided with several numbered numeric keys. Then, the corresponding number in the operation information storage section is displayed on the liquid crystal display, and the HREF attribute value corresponding to the pressed key is transmitted. An example of the display on the display unit in this case is shown in FIG.
Shown in In this case, the numbers displayed on the liquid crystal display correspond in order from the top of the hotspot displayed on the display unit of the main body. (3) In the present embodiment, the extraction information transmitted from the main body to the remote control device includes the HREF attribute value, but the extraction information is not limited to this. For example, it may be a NAME attribute value. (4) In this embodiment, the information acquired by the control unit 112 is an HTML document used in WWW, but it may be, for example, an SGML document having the same kind of logical structure. Further, although the WWW server is used as the acquisition source, it may be information obtained via television broadcasting or a communication medium, or information from an external storage medium such as a DVD or an IC card.
