Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for converting music data in a homepage at various sites on the World Wide Web (hereinafter referred to as music data in a homepage) into a predetermined scenario via the Internet or the like. The present invention relates to a device for automatically displaying information along the line and a method for automatically controlling the display of music data in a homepage.

[0002]

2. Description of the Related Art Conventionally, various web browsers have been known as browser software for browsing homepage information which is information on homepages on the Internet (hereinafter referred to as both top pages and other pages of each site). Have been. Using this browser software, the user browses homepage information one after another and enjoys so-called internet surfing.

[0003] However, this surfing is based on the user's completely active action. Because of this, when a user visits a particular site, it is not clear what important information is in it,
It takes time to browse all pages of the site, or to skip and read only predetermined pages by intuition. Also,
Active browsing of each web has some discretionary and preferable aspects for the user, but it is labor-intensive and often cumbersome. On the other hand, as a so-called content provider that provides homepage information, there may be a page that the accessing person particularly wants to see in the site.

[0004] Recently, push technology and pull technology have emerged. Among them, the push technology uses the server 81 as shown in FIG.
Is distributed to a plurality of contract clients 82 via the Internet 83, and can be said to be a kind of newspaper delivery. As a variation of this push technology, which periodically sends information, the user installs the software, automatically accesses the server registered with the software, and if the information is updated, the information is updated. Incoming technologies are also starting to be used.

[0005] Further, as shown in FIG.
In the header 91 of a specific homepage 91 written in an HTML (Hiper Text Markup Language) document, for example, "The next display is page B. Display page B in 10 seconds." Link the home page to be displayed. Then, a link to the C page is described in the header 92a of the home page 92 to be the B page. Further, a link to the D page is described in the header 93a of the home page 93 serving as the C page. In this way, the link destination is described one after another. As a result, the client as a user can browse the home page one after another by pulling down the home page 91.

[0006]

In the conventional push technology, the homepage information is transmitted to a plurality of contract clients 82 or the like one after another or simultaneously, so that the server 8
1, a large load is applied. For this reason,
It becomes necessary to make the server 81 large and expensive. In the push technology shown in FIG. 11 or the push technology in which a registered server is automatically accessed and the information is updated if the information is updated, the client side to be delivered has a completeness. Being passive, the client sometimes also receives unnecessary information.

In the conventional pull technique, it is necessary to write a description such as a link description in the headers 91a, 92a and 93a of the home pages 91, 92 and 93, respectively. Therefore, in order to adopt this pull technique, it is necessary to change the conventional description. Moreover, the description is different for each page. In addition, to change the link relationship, it is necessary to change the descriptions of all pages affected by the change again. Such an operation is extremely troublesome, and a link error tends to occur. In particular, when the latest information is required, such as music information, and its sales and popularity change rapidly, the work of changing the link relationship is extremely troublesome and requires a great deal of labor.

In view of the above-mentioned problems, the present invention does not impose a load on the server of the homepage information provider and hardly puts extra effort when creating contents, etc. From to the next,

May be applied. The connection between the ISDN 5 and the personal computer 4,
DSU (Digital Service Unit), terminal adapter, modem, I
A connection means to a network such as a P-router is used.

Network display 1, 1a, 1b
(Hereafter, network display 1
2), as shown in FIG. 2, a display unit 11 made of a liquid crystal at the center, an operation unit 12 arranged around the display unit 11, a speaker unit 13 for outputting sound, a specific web page. It is mainly composed of a magnetic card reader unit 14 for reading a magnetic card that can be accessed to read the address and reading other magnetic cards, and a connection unit 15 connected to a power supply line or the personal computer 4 as a host. .

The left and right operation units 12 of the display unit 11 are 1-1
0, there are ten types of menu buttons 12, and each of these buttons 12a
The corresponding operation menu is displayed on the display unit 11 close to. For example, various animations stored in the personal computer 4 are selected by their numbers. That is, when the first menu button 12a is pressed, 1

Is provided.

The circuit configuration of such a network display 1 is as follows. That is, as shown in FIG.
(Liquid Crystal) Display Unit 11 and CPU as Control Means
An instruction from a memory (= central processing unit) 21, a dedicated graphics LSI 22, a program ROM 23, and an external information source 24 such as the personal computer 4 is transmitted to the CPU memory 21 or an instruction from the CPU memory 21 is transmitted to the personal computer 4. Data transmission / reception circuit 25 to communicate and dedicated graphics L
A VRAM (video ram) 26 connected to the SI 22;
A sound circuit 27 for supplying sound to an external amplifier or speaker unit 13; and a display unit LS for driving and controlling the display unit 11
I28 and a memory 29 for storing a display program and the like. Note that the speaker section 13 and the sound circuit 27 constitute a sound reproducing unit.

The external information source 24 is located outside the network display 1 and controls the display contents of the network display 1 on a very large scale.
In the program ROM 23, the CPU memory 21 receives specific data from a web browser or a display program, receives a program for controlling display, and receives a command from the external information source 24, and switches the display flow. And a program for performing processing for displaying the specified specific image at the specified specific position.

Here, the dedicated graphics LSI 22
Is controlled by the CPU memory 21 for controlling the sequence between the screens. On the other hand, the display of a series of images and sprites in each screen is performed by looking at the programs and data in the memory 29 and using the programs and data. Thus, a series of movements of the sprite and the like are controlled. Further, the VRAM 26 can take in two screens. The reason why two screens are used is that one screen is used for display and the other screen is used for writing. This two-screen method eliminates flickering during writing and improves image quality. The sound circuit 27 is an 8-bit, 8 KHz, one-channel sound circuit.
Other values can be used as appropriate.

A program for automatically displaying homepage information (hereinafter referred to as a display program) is installed on the memory 29 or the hard disk (not shown) of the network display 1. This installation
The information is distributed and distributed by communication using the Internet 2 or another network. If the network display 1 is provided with an information storage medium reading unit such as a CD-ROM reading mechanism, the information storage such as a CD-ROM can be performed. A medium may be used.

On the other hand, homepage information to be accessed,
For example, a scenario script is described in homepage information written on another WWW server 6a. In addition,
A link list to the page in which the scenario script is described may be written on the top page. The scenario script has scenario-related information composed of scenario information and control attributes, and a comment, and is described in the HTML file using a script tag. For example, <script language = "XXX Script"> ... </ scrip
t>. The display program finds this script tag, and when "OO Script" is written therein, the display program is activated.

The scenario information and the control attribute are written between the script tags as follows. That is, the scenario information is written in the Page attribute. And HTM
In the L file, scenarios are set in the order in which they appear while being surrounded by script tags. The description of the scenario information is Page = "http: //........../123.html" Page = "http: //.........../abc/ html "Page =" http: //.........../xyz/jpg "

The control attribute is for adjusting the display mode based on the scenario information, and can control the following five functions. The first is to control the presence or absence of user intervention. UserCtrl = "ON" or UserCtrl = "OFF"
Is described. The former description allows the accessing user (client) to control the display speed. If the latter description is made, control by the user becomes impossible, and the display is performed as described. Note that the initial value is "ON". The second is “Interval” that controls the time interval of page switching, from 1 (= Short) to 1
An integer value for 0 seconds (= Long) can be set. For example
If Interval = "3", pages are switched at intervals of 3 seconds. The initial value is 5 seconds.

Third, the scroll speed for moving the display portion when one page does not fit on the display screen is "Sc
roll ". The setting can be switched in 20 steps from low speed to high speed.
In this embodiment, scrolling is always performed, but scrolling may be turned off.
Fourth, "Loop" that controls the number of repetitions of the scenario
Thus, an integer value from "-1" to "127" can be set. Here, “0” is interpreted as the same as “1”, and “−1”
Becomes an infinite loop. Note that the initial value is one time. Fifth, when the line of the network is not high-speed, a function for pre-reading the next page and the music data of the displayed page and registering the music data in the cache of the browser software to perform the switching to the next page at high speed is called “PreLoad”. ]. The setting is enabled when "ON" and disabled when "OFF".

FIG. 4 shows a description example of the above-described scenario information and control attributes. "<!-" Shown in this figure.
"-" Is a comment tag, and the end of a comment in a normal web browser is described as "->." Therefore, when this display program is used, in the example of FIG. However, the part is detected without being commented out.However, in a normal web browser, the lines from the line indicated by arrow A to the line indicated by arrow B in Fig. 4 are commented out and ignored. When a source command in the web browser is selected, the contents can be displayed.

Next, the operation of the network display 1 configured as described above and having the display program installed therein will be described.

First, the power is turned on, and the network display 1 is brought into an operating state. Then, it is connected to the Internet 2 via the LAN 3, the personal computer 4, the ISDN 5, and the WWW server 6. At this time, the connection is made using the operation button unit 12b for Internet access and the instruction operation unit 12c. Thereafter, as shown in the flowchart of FIG. 5, the web browser is first started (step S11). Next, the display program is started (step S12). Note that the web browser may be automatically started by starting the display program.

When the display program is started, a main dialog box 31 as shown in FIG. 7 is displayed in the case of the personal computer version (hereinafter referred to as PC version). However, in the case of the network display 1, a main dialog box 31 as shown in FIG.
b or the like may be used instead. Here, the first
The slide button display section 32 can change the page switching interval with a page switching time interval setting slide. The second slide button display section 33 thereunder can change the scroll speed with a scroll speed setting slide.

The button screen displayed with “>” is a forward button 34 for moving to the next page, and the button screen displayed with “<” is a back button 35 for moving to the previous page. The button screen displayed by “‖” is a pause button 36 for switching between the automatic patrol mode and the manual patrol mode, and the button screen displayed by “STOP” is a stop button 37 for ending patrol based on the display program. ing. The end button 38 composed of the "QUIT" button screen and the "x" mark at the top right end this display program to end the display of the main dialog box.

In this embodiment, the display program operates by acquiring information of the web browser present at the time of startup. That is, first, in step S13, the display program reads the HTML file of the web browser. Note that even if the web browser reads the scenario script while the display program is not running, it is ignored.

All Hs read by the web browser
The TML file is delivered to the display program and processed. Then, the CPU memory 21 determines whether or not there is a scenario script in the delivered HTML file (step S14). If there is a scenario script in the HTML file, the display program extracts and analyzes scenario information and control attributes from the scenario script (step S15). If no scenario script exists, the web browser will operate normally. When another homepage information is accessed under the control of the user (step S16), the process returns to step S13 and repeats the same operation.

Based on the result of extracting the control attributes, the CPU
The memory 21 determines whether the user can perform the control (step S17). When UserCtrl = "OFF", CPU
The memory 21 determines that the result is negative, and makes the display other than the end button 38 and the upper slide button display non-display areas 32 and 33 in the main dialog box 31 thin to make the control impossible display (step S18). Then, the display program starts the control of the web browser (Step S).
19). Thereafter, the homepage information is accessed one after another based on the scenario information (step S20). That is, the network display 1 downloads and displays the home page written in the scenario script one after another. The display at this time is performed by a web browser. After the predetermined page is displayed, the system waits for the switching time interval set in the scenario script, and then downloads the next page.

When all the first scenarios based on the scenario information are completed, the scenarios are repeated according to the set loop parameters. The exchange of information between the display program and the web browser is performed by OLE (Object Linking and Embodding) automation or DDE of the application interface of the web browser in the case of the PC version, and the function of the library in the case of the network display 1 or the like. It is realized by calling.

Set scenario (including loop count)
Is completed, the display program ends the control of the web browser (step S21). Then, the display program displays the page with the link of the page on which the scenario script is written, and ends the control (step S22). Thereafter, if the user accesses other homepage information (step S23), the process returns to step S13 and repeats the steps from step S13.

In step S17, if the user's control is possible (UserCtrl = "ON"), the CPU determines that the control is affirmative, and the main dialog box 31 shown in FIG.
Each display of the control unit such as each button is darkened (step S31). Then, control of the web browser is started (step S32). At that time, the display program
First, automatic patrol is started based on the settings described in the scenario script (step S33). After that, CP
The U memory 21 determines whether the pause button 36 has been pressed (step S34), whether the stop button 37 has been pressed (step S35), and whether any other button or the like has been pressed (step S36). If the user does nothing, the automatic patrol continues.

When the pause button 36 is pressed, the mode shifts to a manual patrol mode that can be controlled by the user (step S3).
7). Thereafter, the scenario is moved forward and backward by pressing the forward button 34 and the back button 35. In this manual patrol mode, page switching does not occur unless any button is pressed. In this manual patrol mode, the CPU memory 21 stores the pause button 36
Is monitored (step S38), whether the stop button 37 has been operated (step S39), and whether other control has been performed (step S40).
When no operation is performed, the user only scrolls the page, and after the scroll is completed, the page is continuously displayed.

When the stop button 37 is pressed in the automatic patrol mode, the display program terminates the control of the web browser (step S41), and displays the page with the link of the page where the scenario script is written. The scenario ends (step S42). Thereafter, when the user accesses another homepage (step S43), the process returns to step S13 and repeats the above steps.

When a button other than the pause button 36 and the stop button 37, for example, an end button 38 is pressed in the automatic patrol mode, the display program itself ends and the first slide button display section 32 is operated. Then, the page switching interval can be changed. In this way, control according to the operation is performed (step S44). In the automatic patrol mode, the display of the forward button 34 and the back button 35 becomes thin, and the operation of these buttons cannot be performed.

When the pause button 36 is pressed in the manual patrol mode, the flow returns to the automatic patrol mode and the steps from step S33 are executed. When the stop button 37 is pressed, steps S41 and S4 similar to those in the automatic patrol mode are performed.
Steps S2 and S43 are executed. Further, when an operation other than the pause button 36 or the like is performed in the manual patrol mode, control is performed according to the operation (step S44). In the manual patrol mode, the display of the main dialog box 31 is all dark, and all controls are possible. Whether or not the automatic patrol has been completed according to the setting is confirmed in step S45, and if the determination is affirmative, the process proceeds to step S42. If the determination is negative, the process returns to step S33.

Here, an example in which music data is automatically displayed will be described. First, music company A
Homepage 5 for music information as shown in (A)
Create 1. The description for displaying the best 10 sales of CDs and the best 10 karaoke songs is described therein. Then, link to each part of the list. For example, when a part of the sales top 10 is clicked, as shown in FIG. 8 (B), the user is caused to jump to a homepage 52 relating to other music information in which the titles of the top ten to the tenth sales are described.

In the HTML document 53 of this homepage, the pages of each song are arranged in the order of the scenario information 5.
4 is sequentially described. On the other hand, as shown in FIG.
Introduction pages 61, 62, 63, 64, 65, 66 for each song
For example, music data, for example, a description that introduces the song, character information W such as a poetry portion, and image information Y such as an image of a singer are embedded. In this case, if the ranking at that time is the ranking of A tune, D tune, C tune, F tune,..., Based on the scenario, the order is as shown on page 61, page 64, page 63, page 66. You can browse each home page in order. Even if the order is changed, it can be dealt with only by changing the description of the scenario. Note that the song introduction pages 61, 62, 63, 64, 65, 66, etc., describe only the character information W, describe only the image information Y, or describe both. Is also good.

In some cases, music data, that is, sound data Z such as a song itself may be inserted. That is, for example, the sound file 7 in which the sound data Z is included in the introduction page 61
A description to link with 1 is made. This way, when the introductory page is loaded into the web browser,
In addition to displaying characters and images, the singer's singing voice can be heard, which is preferable in terms of interest.

The automatic display device 1 and the display program for music data in the homepage of this embodiment can automatically display homepage information, for example, music information and music data one after another according to a predetermined scenario. As a result, the user can enjoy music information and music data just by watching, instead of active information browsing. In addition, in implementation, it is possible to weaken the interactivity by making user control impossible. In such a case, it is conceivable to use it for demonstrations at stores and shows, advertisement towers, and the like. On the other hand, by allowing user control, you can take advantage of interactivity, stop scenarios midway,
It is possible to realize reverse rotation and advance without applying any special load to the server. In addition, since most of the automatic display device 1 and the display program are technologies realized on the client side, a standard HTTP server serving as a WWW server can be used, and maintenance other than normal maintenance is not required. . On the other hand, the only task on the service management side is scenario creation.

In the above-described embodiment, there is no need to install a server dedicated to this display program, and the HT
It is only necessary to add a dedicated tag to the ML file. As described above, regardless of the type of server, the editor and H
Anyone with a TTP server can easily become the originator of a scenario. In addition, a scenario can be branched. That is, a scenario script is detected every time an HTML file is read. Therefore, if another scenario script exists in a certain file in the detected scenario script, the scenario is switched. As described above, the script tag in the scenario script is harmless in an environment without this display program, and normal display is performed by a web browser without this display program.

Network display 1 as described above
FIG. 10 shows an example of how to use this in a closed state without connecting to the Internet 2. A plurality of network displays 1 are connected to one personal computer 40. Although an image is displayed on the entire screen of the personal computer 40, only a part of the image is displayed on each network display 1. However, in each network display 1, the contents of the entire screen can be grasped by scrolling a part of the screen on the personal computer 40 by the scroll function. By making the data compression method of the network display 1 reproducible only by software, it is possible to eliminate the need for dedicated hardware, which is advantageous for miniaturization and cost reduction.

Further, if only a part of the image is displayed instead of the entire image of the personal computer 40 as shown in FIG. 10, it is not necessary to decode the entire image.
The display memory can be reduced. The size of the display memory and the size of the display panel may be changed depending on each network display 1. For example, one network display 1 can display “ABCD” and another network display 1 can display “ACD”.
B "may be displayed, and the other root and the work display 1 may be sized to display only" A ".

Although the above-described embodiment is an example of a preferred embodiment of the present invention, the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. is there. For example, it can be used not only for the Internet 2 but also for various networks such as a network only in a specific company called an intranet. That is, the present invention can be applied to any system having a WWW server that handles HTML files.

When the scenario is branched, in the above-described embodiment, when the scenario at the branch destination ends,
Since the patrol scenario ends at that point, the memory capacity can be reduced. However, when there is enough memory, the scenario may return to the original scenario when the scenario at the branch destination ends.

In the above-described embodiment, a script rung edge is used as a description when the display program detects the existence of a scenario script, such as <SCRIPT LANGUAGE = “OOO”>. Other tags may be employed. For example, various methods such as detecting a predetermined text sentence or the like written in a comment tag and incorporating a scenario into a display program can be adopted.

Further, the display program may be stored in an information storage medium, and the medium may be read by a personal computer or the like and executed. Various media such as CD-ROM, digital video disk, mini disk, removable hard disk, floppy disk (including those with high compression), memory cartridge, flash memory, and tape medium are used as the information storage medium in such a case. it can. Moreover, in addition to a read-only type such as a CD-ROM, a readable and writable type such as an HDD may be used, and a disk-shaped type such as a DVD, a memory itself such as a flash memory, and the like. Media of various shapes such as a tape-like medium such as a digital audio tape (DAT) can be used.
In the case where the program is distributed via a network, a hard disk provided in a host computer or the like serving as a distributor serves as an information storage medium.

In the above-described embodiment, the scenario script is embedded in the homepage of the WWW server. However, an HTML file containing the scenario script is stored in a device at hand, such as the network display 1, and the HTML file containing the scenario script is stored. The HTML file may be read into the display program first, and then circulated along the scenario. In this way, it is possible to easily create and execute a patrol scenario that suits each user's preference.
