Description

DETAILED DESCRIPTION OF THE INVENTION (Field to which the invention pertains) The present invention relates to a display document switching method in a shoe display system that enables simultaneous display of the same document between a plurality of communication terminals connected via a communication line. It is related to.

(Prior Art) Conventionally, in this type of device, when a local terminal locally displays a document different from that of the other party's terminal, and then attempts to display a document that the other party's terminal is displaying, the own terminal displays a document different from that of the other party's terminal. Request a resend of the matateme number of the document displayed on the terminal,
The document had to be received again from the other party's terminal, which made the procedure for displaying the same document complicated and took a long time to display. For this reason, there has been a problem in that it poses a problem when a person wants to temporarily view a document different from the document being explained by the presenter during a communication conference or the like.

(Objective of the Invention) The present invention solves the above-mentioned drawbacks, and makes it possible to independently display a document different from that of the other party's terminal with which communication is being carried out. It is characterized by displaying the same document, and its purpose is to display a common document between multiple communication terminals in a communication conference where the conference progresses, and to display a document other than the one being explained at any time. To make a meeting more similar to a meeting in an actual conference room and to proceed with the meeting efficiently by displaying the same document for reference and immediately displaying the same document as the other party's terminal.

(Structure and operation of the invention) FIG. 1 shows the structure of an embodiment of the invention, in which 1 is a document display device A, 2 is a display device B, 3 is an exchange, 4 is a communication line, and 5 is a communication line. A communication control section of the document display device A, 6 is a system processing section, 7 is a display control signal storage section, 8 is a document storage section, 9 is a read/imprint section, 10 is a display control section, 11
12 is a display section, 12 is an operation instruction section, 13 is a communication control section of document display device B, 14 is a system processing section, 15 is a document display control signal storage section, 16 is a document storage section, and F is a reading/writing section. , 8 is a display control section, 19 is a display section, and 20 is an operation instruction section.

In explaining the operation, the document display device A1 and the document display device B2 already communicate via the exchange 3 and the communication line 4, and store documents to be used for meetings, etc. in the document storage units 8 and 16 of each device. shall be stored and managed by . Further, unless otherwise instructed, each of the document display devices A1 and B2 is set to display a co-moving document between them when participating in a conference.

First, the user inputs the document number of the document to be displayed from the operation instruction section 12 in the oath display device A1. System processing section 6
Further, a document signal corresponding to the oath number is read out from the document storage section 8 and sent to the display section 1 via the writing section 9 and the display control section 10.
1. Further, at the same time as the operation control, the document number inputted from the operation instruction section 12 to the communication control section 5 is transmitted to the document display device B via the communication circuit IIJI4.
2 to send it. As a result, document display device A
A document to be displayed is displayed on the display device B1, and its document number is sent to the document display device B2.

In the display device B2, when the communication control unit 13 receives the document number, the document number is transmitted and stored in the document display control signal storage unit 15, and then sent to the system processing unit 14. The system processing section 14 also reads out the document corresponding to the document number from the document storage section 16 via the reading/writing section 17 and displays it on the display section 19 via the display control section 18.

Through the above operations, document display device AI and document display device B2
displays the same document at approximately the same time. Subsequently, when the document numbers of the documents to be displayed are sequentially input from the operation instruction unit 12 of the Matahoma display device A1, the above operations are repeated until the documents desired to be displayed are sequentially displayed between the two devices.

Next, an explanation will be given of the operation when, in the above state, the document display device B2 displays a document different from that on the document display device A1, and then displays the document displayed on the display device AIK again.

When an instruction request to temporarily store the document number received by the communication control section 13 (i.e., a local display mode request) is input from the operation instruction section 20 to the system processing section 14, the communication control section 13 The received document number is stored and held in the document display control signal storage section 15 in a form that overwrites the previously stored document number, and is not sent to the system processing section 14. Here, when the document number to be displayed is input from the operation instruction section 20 of the document display device B2,
The system processing section 14 reads out the document corresponding to the document number from the honor storage section 16 to the display section 19 via the reading/writing section 17 and the display control section 18, and displays the document.

Following this operation, in the document display device B2, when an instruction request to display the same document as the document displayed on the document display device A1 (i.e., a common display mode request) is issued from the operation instruction section 20, the system processing section 14 is a Matama number (i.e.,
The document number received most recently) is retrieved, and the document with that document number is read out from the document storage section 16 and displayed on the display section 19.

As described above, in the present invention, by having means for accumulating and holding the latest document number of a document that is commonly referred to and displayed between devices during local document display, common display during a conference can be performed immediately when necessary. You can return to the document.

Note that in the above description, document display control signal storage units 7 and 1
5 temporarily stores only the most recently sent/received document number and displays the latest document, but the document displayed immediately before the latest commonly displayed document or the one before that If it is desired to display a message, this can be easily done by increasing the capacity of the buffer memory that temporarily stores the document numbers to be sent and received.

Next, we will take an example of a communication terminal that has a function that can assist document explanations by sending display control information such as rotation, enlargement, compression, and movement for documents that are displayed simultaneously between multiple communication terminals. The operation of the display document switching method will be explained in more detail.

FIG. 2 is a diagram showing details of the configuration of the document display control signal storage section 7 of the communication terminal having the above function.

The table also shows the control operating conditions in FIG.

In FIG. 2, 100 is a document display control signal identification unit;
01 i, 1. A write register, 102 is a temporary storage register, 103 is a read register, 104 is a sofa control unit, 105 is a write pointer, 106 is a read pointer, 107 is a batch read display unit, 108 is a common/local mode display unit, 109 is an explainer/audience mode display section, 110 is a gate, 500 is a reset signal edge X,
600 is a write instruction signal line, 700 is a reset signal iY
, 8.00 is the read notification signal M, and 900 is the reset signal edge 2.

First, the common display mode will be explained. In the common display mode, the common/local mode display section 108
is set to the common display mode, and unless otherwise instructed, the batch readout display section 107 is set to an off state (batch readout unnecessary state).

Also, the presenter displays and controls the common documents using other communication terminals, and the communication terminals to be explained from now on are terminals in audience mode that operate by receiving these various document display control signals. . That is, the explainer/audience mode display section 109 is set to audience mode (a state in which the gate 110 is opened and information is passed through).

Now, various communication information transmitted via the communication circuit Iw4 passes through the communication control section 5, and then passes through the document display control signal identification section 1.
00. The display control signal identifying section 100 determines whether the signal is a document display control signal or another signal (for example, device failure notification information, etc.), and sets only the document display control signal in the pledge register 101. Other signals are sent directly to the system processing section 6 via the gate 110.

In addition, in the case of a document display control signal, the document display control signal identification unit 100 further determines whether the signal is a document number or a display control signal such as rotation or movement, and when the document number is a document number, a reset signal is sent. Activate line X500. As for the document display control signal, a sentence ** indicating the document to be displayed is first transmitted, and thereafter a display control signal for controlling the displayed document is transmitted at any time. Therefore, the operation will be explained in accordance with the transmitted document display control signal.

When the received document display control signal is a document number, the document display control signal identification unit 100 stores the document number in the write register 101K, and also resets the write pointer 105 and read pointer 106. Activation of signal edge X 500, temporary memory buffer 7a 10
Write instruction signal to store the document number in 2 @
600 is activated. The buffer control unit 104
When a start signal is received from each signal line, the write pointer 105 and read pointer 106 are reset (the pointer position indicates the beginning position of the temporary storage buffer 102).
After that, the write register 101K stores the number 11, and the write pointer 105 points to the address K1 of the temporary storage computer 102, 1 degree pointer 10.
Take 5 one step forward. Furthermore, the 1-buffer control unit 104 checks the 7 lag of the common/local mode display unit 108, and since it is the common display mode, following the write operation, the content of the temporary storage buffer 102 indicated by the read pointer 106 (i.e. , the document number written just before),
Read to the read register 103, read notification signal m s
oo is activated to notify the system processing unit 6 of the readout, and advance the contents of the readout pointer 106 by one step. When the system processing unit 6 receives the read notification signal, the read register 1
The document number of the document to be displayed is read from 03 and displayed on the display section 11 according to the procedure explained in FIG.

When a display control signal such as rotation or movement is received following the document number, the document display control signal identification unit 100 stores the display control signal in the write register 101, and also stores the display control signal in the temporary storage buffer 102K. In order to store the signal, an activation signal is transmitted through the honor input instruction signal GL 600 and the buffer control unit 104 . The buffer control unit 104 writes the display control signal to the address of the temporary storage buffer 102 indicated by the write pointer 105,
Advance the write pointer by one step. Furthermore, the buffer control section 1
04, since the common/local mode display unit 108 is in the common display mode, performs the same operation as the document number reading operation described above and sends the display control signal to the system processing unit 6. The system processing section 6 controls the display of the document displayed on the display section 11 according to the display control signal.

Next, the operation when switching from local display mode to common display mode will be explained.

During the meeting, the communication terminal is always online connected to the communication terminals participating in the meeting, and it is possible to send and receive communication information. At this time, while the document is being displayed locally in the local display mode, the display control signal transmitted via the communication recollection will be sent to the temporary storage buffer 7a according to the table above.
02. However, since the common/local mode display section 108 is set to the local display mode, no read operation from the temporary storage buffer 102 is performed. In this state, when an instruction to switch from the a-cal display mode to the common display mode is given, the system processing section 6 sets the common/local mode display section 108 to the common display mode, and also sets the batch readout display section 108 to the common display mode. 107 is set to the on state (-pattern display mode) K. Then, an activation signal is delivered from the reset signal line Y 700. When the buffer control unit 104 receives the activation signal from the reset signal line Y700, it resets the read pointer 106, and then reads the read pointer 106 from the temporary storage buffer 102.
reads the contents addressed by to the read register 103,
A read notification is sent to the system processing unit 6 through the read notification signal line 800. When the read notification is completed, the read pointer 106 is subsequently advanced by one step, and the content addressed by the read pointer 106 is further read from the temporary storage buffer 102. These operations are performed using the read pointer 10.
6 and the value of the convolution pointer 105 are repeated until they match. It is possible that a document display control signal is received via the communication line 4 during this operation, but in this case, the operation is performed according to the table above.

As described above, when the batch reading of the document display control signals stored in the temporary storage buffer 102K is completed (that is, the indicated value of the read pointer 106 = the indicated value of the write pointer 105), the buffer control unit 104 connects the reset signal line z9.
00 and sets the batch readout display section 107 to the off state.

As described above, display document switching on the communication terminal in audience mode is executed.

On a communication terminal in explainer mode, the explainer temporarily suspends the commonly displayed document that he or she is using for explanation, displays another document locally, and then returns to the original commonly displayed document. In this case, the display document switching method is exactly the same. In that case, it is necessary to input the communication information to be transmitted into the document display control signal storage section 7. In addition, a presenter/audience code display section 109 is provided to discard all information other than the document display control signal in the result classified by job by the document display control signal identification section 100 when in the presenter mode (i.e. , the gate 10 is controlled so as not to be delivered to the system processing section 6).

The above table summarizes the operating conditions of the display document switching method described in detail above.

(Effects) As explained above, the method of the present invention is capable of displaying the same document as the other terminal during communication, or a document specified by the Hiroji terminal at any time. After displaying the same document, you can immediately display the same document as on the other party's terminal. Therefore, when displaying documents and proceeding with a teleconference, each individual can read out the necessary documents locally when necessary, to help understand the conference documents, or to select specific documents, just as in the case of an actual conference. In addition to being able to read the conference document carefully, it is also easy to immediately display the conference document and participate in the conference, which has the advantage of being user-friendly and making it possible to proceed with an efficient teleconference.
