Abstract

PURPOSE:To attain a document conference between many places, by accessing from one document conference terminal simultaneously to two terminals or more and also accessing a data base center during the conference if necessary to take out and display necessary information. CONSTITUTION:The user of a document conference terminal 120A inputs retrieval information 302 indicating the address information 301 of the data base center 202 and retrieval information 302 indicating retrieval data from an operator 103 to transmit these information. A pair of information 301, 302 sent from the terminal 120A are sent to a packet multiplex station 200A through a circuit and the multiplex station 200A forms packets of these information, inserts them into communication information between other terminals under time division and sends them to a packet exchange 201A through a circuit as packet information 303, 304. The exchange 201A separates the input information into the packet 303 to the data base center 202 and the packet 304 to the opposite document conference terminal 120B and transmits these packets to respective terminals. The conference terminal 120A transmits the information obtained from the data base to the conference terminal 120B, the communication opposite, to display the information.

Description

[Detailed Description of the Invention] This invention relates to a document conference method that connects remote conference rooms with communication lines, sends and receives document image information and audio information, and reproduces the information in each conference room to conduct a conference. be.

<Prior art> In the conventional document conference system, a communication line is set up between conference rooms at two locations, and a conference is conducted by transmitting and receiving documents and audio information1. , ”J
However, it was not possible to hold meetings between three or more locations. As the communication line is still only set up between the other conference room, it is not possible to access the database center or personal file device during the meeting and output the necessary information to make it useful for the meeting. could not.

<Summary of the Invention> The present invention eliminates these drawbacks by making it possible to set up communication lines from a communication room to two or more parties at the same time. Therefore, according to the present invention, a packet switching system is used to transmit the address of the other terminal and the information to be sent to the other terminal as a pair, and the paired signals are packet-multiplexed, and each packet is sent to the packet switching center. The destination signal is used as its address information, and the distribution is exchanged for each destination address.

Practical Example> Fig. 1 shows an example of the configuration of a document conference terminal used in the method of this invention. The document conference terminal has a facsimile 100 that inputs and outputs handwritten or printed document images used in the conference, a floppy disk device 101 that inputs and outputs documents created with a word processor, etc., and input from the facsimile 100 and the floppy disk device ff'&101. a heavy-duty file section 102 that stores document images that have been retrieved; and an operating device 1 that inputs and outputs search information and display control information for input sentence 1.
03, an iii control unit 104 that controls document storage, display, transmission, etc. by the output of the operating device 103, and a iii control unit 104 that stores and refreshes the document image information read from the document file unit 102 for displaying the document. It includes a refresh memory section 105 that repeatedly reads out the signal as a signal, and a document display section 106 that displays the refresh signal as an image. This document conference terminal is connected to a communication network via a communication line 107 by a control unit 104 .

The general operation of a document conference using this document conference terminal is as follows. Prior to the meeting, users should send fax number 100.
Alternatively, a handwritten document, a printed document, or a document created with a word processor is input from the floppy disk device 101 to the document file section 102 . Document file section 102
Then, these documents are organized into pages, assigned addresses, and stored. At this time, a table of contents for the document is created and stored as necessary. These document files are transmitted through communication line 10.
7 and is stored in the document file section of the document conference terminal that is the communication partner.

At the time of a meeting, the user inputs the address of a necessary document into the operation section 103 and pulls out the target document page from the document file section 102. At this time, it is also possible to first display the table of contents page, find the desired page based on it, and input the address to retrieve the target page. This search address information is also transmitted to the communication partner's document conference terminal via the communication line 107, and the same page is retrieved from the document file section. This retrieved document page information is transferred to the refresh memory section 105, and then continuously and repeatedly read from there, and the retrieved document page information is displayed on the display section 106. The same document content is simultaneously pulled out and displayed on the communication partner's document conference terminal, so the user can conduct a remote conference in these conference rooms while viewing this document.

FIG. 2 shows a system configuration in which a conference is held using the above-mentioned document conference terminal, and data files can be accessed during the conference. Document conference terminal 120A.

Figure 3 ta+ shows an example of information sent from the document terminal.
'ld (b) shows examples of information sent from the packet multiplexing layer.

Next, the operation of remote document conference including database center access will be explained using FIGS. 2 and 3.

The state in which documents are sent and received at each document conference terminal before the meeting and the conference is held is similar to the operation described above. Next, consider a case in which, for example, a user of the document conference terminal 120A accesses the database center 202 during a meeting, retrieves data stored in the center 202, and uses the data for the meeting.

The user of the document conference terminal 120A inputs address information of the database center 202 and search information indicating search data using the operating device 103. This information is sent to the document conference terminal 12.
As shown in FIG. 3(a), 0A sends out the address 301 of the database center 202, which is the communication partner at this time, and the search information 302 as a pair. This paired information is passed through the communication line 107A to the packet multiplexing layer 200.
Transmitted to A.

In the packet multiplexing layer 200A, the pair of destination address and information take as shown in FIG.
11÷ is packetized and inserted into the communication phase between other terminals in a time-division manner, and sent to the packet switching center 2 through the communication line 108A as packet information as shown in FIG. 3 (bl).
Send to 01A.

The packet switching center 201A separates the packet 303 destined for the database center 202 from this packetized information based on the destination address and the packet 304 destined for the communication partner's document conference terminal 120B. Transmit each packet to its destination. In other words, search information to the database center 202 is sent via the communication line 110.
The information is transmitted to the database center 202 via 108C and 107C, and the information to the document conference terminal 120B is sent to the document conference terminal 12 via communication lines ioc+, 1osB, and 107B.
Transmitted to 0B.

When the database center 202 receives the search information 302, it searches for the requested information and sends the requested conference terminal 12.
Transmit to 0A in the opposite direction to the above. The conference terminal 120A displays this take on its own terminal display section 106, and also transmits and displays it to the teleconference terminal 120B, which is the communication partner.

In this way, in both meeting rooms, it is possible to access the database center 202 during the meeting and search for and display takes as needed. In addition, by transmitting an address and information as a pair, and transmitting the address and information as a pair at the packet exchange station to the destination station using the address of the valley pair, it is also possible to conduct document communication between three or more points.

However, the database center 202 described above is not a general-purpose database center, but is, for example, a document conference terminal 120.
It is clear that the office computer terminal owned by A's first user, Nobuai, has the ability to access the data in the above manner, and in this case, if necessary, a written meeting of the court may be necessary. It is obvious that it is also possible to transfer the data from the sentence 1 file section 102 of the terminal 120A, store it, and perform original editing or other processing on the office computer after the meeting is over.

Only one of the facsimile 100 and the floppy disk device 101 may be used as the document input section.

In addition, by using the document input section as a document input/output port, necessary documents used during meetings can be converted into hard copies.
Or you can take it home as a soft copy on a floppy disk.

<Effects> As explained above, in the method of the present invention, it is possible to access two or more terminals at the same time from one document conference terminal, and if necessary, the database center can be accessed on the way to the lady, and the database center can be accessed as needed. Take out and display positive information,
There is an advantage that the information in progress can be transferred to the take processing device, processed, and the results can be outputted.
