Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a block configuration of a display device server and a network-compatible display device of the present embodiment. In FIG. 1, the left side of the dashed line indicates the conference room, and the right side of the dashed line indicates that the client (PC) 1 and the server 2 are outside and are connected to the network. In the conference room, a display device server 4 connected to the display device 3 and clients (referred to as hand terminals) 5 for a plurality of hand terminals are connected to the network. In the display device server 4, an HTTP server 41 for browsing Web pages and connected to the HTTP server 41 to process JAVA applets on the server side for data display and acquisition of operation information on the terminal 5 at hand. The CGI processing unit 43 is connected to the servlet server 42 and further to the HTTP server 41 and adds functions to the html by an external program to store data and the like. The servlet server 42 is connected and the CGI processing unit 43 is connected to the CGI processing unit 43 to display the display data. It has a display mechanism 44 to be generated. Further, the display device server 4 includes a Samba 45 which is an SMB protocol package for acquiring data from the PC 1 outside the network. The Samba 45 is a Microsoft network file system compatible processing unit used in many PCs. If the server OS is Microsoft, the Microsoft network file system itself may be used. Thus, the servlet server 4 is located in the display device server 4 and the display mechanism 44.
2 and the servlet result is input and CG
The storage data by the I processing unit 43 is input, and further the data from the external PC 1 is input to generate display data. The display data of the display mechanism 44 is displayed on the display device 3.
Is displayed in. That is, in the network-compatible display device shown in FIG. 1, a presentation is made by using hand data or external data of the client that is the hand terminal 5. In order to give a presentation using the display device server 4 or the network-compatible display device shown in FIG. 1, data must be obtained. In obtaining this data, the URL and the network file system (NFS (distributed file system software) or the above-mentioned Samba) which are addresses for accessing an external HTTP server for uploading or FTP server for uploading are used to directly obtain the machine name or the like. By specifying an address path including a shared drive name, a definition file in which the files are described in order is created.

FIG. 2 shows an example of a definition file.
Html format file data of TP server (first line),
The description is directly described in the form of a jpg format image file of the FTP server (second line) and a hierarchical file of power points (ppt) (third line). Here, if the data pointed by the definition file is an html file or image data, it can be displayed by a display mechanism equivalent to a normal web browser, and a specific application such as Microsoft PowerPoint which is often used in presentations is used. In the case of data, a html converter is built in the server, a specific application or its compatible software is built in the server, and the generated screen data (often equipped with a viewer for the specific application) is used. Either of them can be displayed via the display mechanism 44. When the definition file for data acquisition is sent through the web browser of the local terminal (client) 5, the server 4 sends the presentation data distributed on the network according to the definition file to an HTTP server, an FTP server, a network file system. And stores it in a storage device such as a hard disk inside the server. Then, when an instruction such as page turning is given to the server 4 through the web browser of the terminal 5 at hand, pages to be sequentially displayed are displayed on the display mechanism 4 in the server 4.
4 is displayed. By doing so, it is possible to give a presentation while the presentation data is distributed over the network.
This means that it is not necessary to collect data as in a conventional PowerPoint.

Before displaying the presentation data, the attribute of the presentation data is set to HT.
The latest data can be displayed by acquiring the data from the TP server, the FTP server, and the network file system and reacquiring the data if the data has been updated. For example, this is effective when displaying data that requires real-time properties, such as stock prices and the progress of tallying. It is necessary to be able to identify a plurality of users for discussion and postscript work at the time of presentation. For this reason, the pointer can be identified corresponding to each terminal. In other words, the processing of the pointer and the processing of page turning, etc. are performed by the JA
It is performed by the cooperation of the VA applet and the JAVA servlet in the server 42. That is, in the processing of each user's pointer, the relative position in the entire screen displayed by the server 4 by the JAVA applet is determined by the server 4.
Send to 2. The servlet on the server side receives this and passes the information to the display mechanism 44 so that a pointer of a shape or color corresponding to each terminal is displayed at a position corresponding to the relative position. In this way, a plurality of persons can simultaneously use the pointer in a state where the user can be identified, and a smooth discussion can be performed. In addition, in the presentation, processing such as transfer and storage of data of the postscript information is performed by a CGI script. In additional writing by line drawing or character input, a bit plane or a text buffer for additional writing of each of a plurality of users is prepared, and additional writing data is written based on information from the local terminal 5. At this time, the information is displayed by the display mechanism so that it can be identified by the shape and color of the line segment, the underline shape of the character, and the color of the character. FIG. 3 shows a state of the additional writing operation by the user A and the user B. A circle or a square is added to the original data in a bit plane, and the original data is identified by the shape of a dashed line or a broken line. In this way, it is possible for a plurality of persons to simultaneously and smoothly perform additional writing work. in this case,
Since the original data does not change like the postscript data, each user can check the data before and after the change. And
The appended data is saved as a file when the page is changed. If the handheld terminal 5 is a client having a high display capability such as a PC, the same data as the data displayed through the display mechanism 44 of the server 4 is displayed on a web browser, and additional writing is performed by an applet. The data can be transferred to the server, written into a bit plane and a text buffer for additional writing of each person, and displayed through the display mechanism 44. By doing so, additional writing can be performed at each local terminal, and the information is displayed when the additional writing is completed, so that the display does not become ugly.

[0010] In storing the additional data, as shown in FIG. 4, if the file name of the additional data is added to the definition file to form a meeting result file, it becomes clear which data has been additionally added, and the minutes can be supplemented. Data can be obtained. Also, the presentation data is all h
In the case of the html format or the html format, <b as shown in the web source of FIG.
ody>, the original data and the additional data become clearer in page units. The file name of the additional data is stored as a name associated with the original data and the file name, such as four lines or lines in the list shown in FIG. In this way, the additional data can be stored in association with the original data and the definition file without any processing. With the display device server and the network-compatible display device as described above, data distributed on the network can be presented, and additional work can be performed without performing complicated operations such as transfer of control authority as in the related art. And a presentation can be performed by a smooth operation.

[0011]

As described above, according to the present invention, for data distributed on a network, data is acquired and stored according to a definition file in which URLs and address paths through the network are described in order, and Since the presentation is performed by displaying the data in order, the presentation can be performed with the data distributed on the network, so that there is no need to integrate the data into a presentation application. According to the present invention, when a presentation is performed, the attributes of the file are acquired to check whether the file has been updated. If the file attribute has been updated, the data is reacquired and the presentation is performed to check whether the file has been updated. Because it is possible, the latest data can be displayed without fail, and the presentation of data with real-time properties becomes possible. Further, according to the present invention, when a presentation is performed, a pointer having a different shape is displayed for each user, so that the pointer can specify the user, so that a smooth discussion can be performed. Further, according to the present invention, when a presentation is performed, by displaying pointers of different colors for each user, the pointer can specify the user, so that a smooth discussion can be performed. According to the present invention, a line drawing is additionally added to a bit plane corresponding to each user by using a line having a different shape for each user when performing a presentation, and the line drawing is used for character input. By adding a line segment as an underline and displaying it, the user can be identified by adding a line drawing or character input, and since the original data itself is not changed, there is no need for complicated work such as delegation of authority. I can do it.
