[0007]

FIG. 1 is a block diagram showing an embodiment of the present invention. The video input h to the video control unit [2] is stored in the memories [4] and [5] selected by the screen selection switch [16].
It is stored in the portion specified by the address signal from the display address generator [3] in [6]. This address signal is applied to each of the memories [4], [5], and [6].
Except for writing video data, the stored video data is read out simultaneously for display and output in synchronization with the display cycle.

The respective data read from the memories [4], [5] and [6] are superimposed with the cursor data from the cursor generator [18], so that the respective cursor signal superimposers [7] and [8]. Video output unit [10] through [9]
The signal is converted into a predetermined signal in [11] and [12] and displayed on the monitors [13], [14] and [15]. Also, for communication between the devices, it outputs its own information [b] such as video information from the video control unit [2] to the line through the line control unit [1]. On the other hand, when information from the partner device arrives from the line, the partner information [a] is input from the line controller [1] to the video controller [2].

Next, the image control unit [2] will be described in more detail with reference to FIG. The partner information [a] from the line control unit [1] is input to the data separating unit 2-1 to separate the partner cursor coordinate value 18-15 and to convert the partner cursor coordinate value 18-15 into the cursor generating unit [ 18].
After the monitor number information included in the partner information [a] is input to the terminal [B] of the switch SW-3, the monitor number information is guided to the decoder 2-8 from the connected terminal [C] to select a memory. d] [e] [f] is given to each memory, and each memory is selected.

On the other hand, the terminal [A] of the switch SW-3 described above.
Is input with the screen selection information 18-16 from the screen selection switch [16] shown in FIG. 1. Similarly, the decoder 2-8 selects the memory [4] [5] [6] at the time of image capturing. The memory select signals [d] [e] [f] are output. The image data is also separated by the data separation unit 2-1 and input to the decoding unit 2-2. Here, after the transmitted image information is decoded, it is input to the memories [4], [5] and [6] as the memory data input [c] through the terminals [B] and [C] of the switch SW-2. .

On the other hand, at the time of capturing an image of the video input [h], image information from the A / D converter 2-3 is similarly input to the memory through the terminals [A] and [C] of the switch SW-2. When transmitting image data, video input [h]
Is converted from an analog signal to a digital signal by the A / D converter 2-3, and then input to the fetch memory 2-5 controlled by the memory address generator 2-4. Street display memory [4]
It is also input to [5] and [6].

The address signal in this case is supplied to the switch SW
The display address generator [3] is preset as a fetched address signal [i] through the terminals [A] and [C] of -1 and added to the display memory as an address signal [g].

On the other hand, the image information output from the capture memory 2-5 is coded by the coding unit 2-6 so as to match the transmission system, and the data superposition unit 2-7 superimposes the cursor coordinates, the monitor number, etc. Afterwards, your information [b]
Is output to the line after being input to the line control [1].

FIG. 3 shows the contents of the partner information [a] and the self information [b] described above. Here, the partner information [a] and the self information [b] take the same form, and cursor coordinate data 1-1, monitor number information 1-2, various control information 1-
3, transmitted and received as a packet composed of image data 1-4 and the like.

Next, the contents of the cursor control relationship will be described with reference to FIG. First, a case where the user moves his own cursor will be described. The vertical direction or the horizontal direction is selected based on the direction selected by the cursor selection switch [17]. This switch information controls the horizontal counter 18-2 of the cursor generating unit [18] and the up-down counter of the vertical counter 18-4. Each of the counters 18-2 and 18-4 receives a clock input from the basic clock generators 18-1 and 18-3, and counts up or down while being selected. Here, the horizontal counter 18-2 counts up while the right cursor in the horizontal direction is selected, and counts down while the left cursor is selected. Similarly, the vertical counter 18-4 counts up while the vertical downward cursor is selected, and counts down while the upward cursor is selected.

The respective counters 18-2, 18-
The output of the switch 4 is applied to the self-match detector 18-5 and compared with the display memory address 18-17. When the output matches, a cursor signal is output, and the switches 18-7, 18-8, 18-
9 is supplied to the input side. The switches 18-7 and 18
-8 and 18-9 are selected by the monitor selection switch [16], are output from the closed switch, and are superimposed on the output of each display memory [4] [5] [6] to be superimposed on the cursor signal superimposing unit [7]. [8] is supplied to any of [9]. In this case, the horizontal counter 18-2 and the vertical counter 1
The counter output of 8-4 has the same data configuration as the previous display memory address.

On the other hand, the display of the cursor of the other party is based on the coordinate value of the other party cursor separated from the video control unit [2] and the monitor number information 18-15 based on the other party match detection unit 18-6 and the switches 18-10 and 18-. 11, 18-12. The other party coincidence detector 18-6 compares the other party cursor coordinate value with the display memory address 18-17, and outputs cursor information at the matched address. The cursor information is the switch 1 selected by the monitor number information.
The signal is supplied to one of the cursor signal superimposing units [7], [8], and [9] through one of 8-10, 18-11, and 18-12.

Next, a specific example of color-coding the own cursor and the partner cursor will be described with reference to FIG. Here, the signal 18-13 of the own cursor is superimposed on the R signal (red) of one of the selected cursor signal superimposing sections. Normally, the R signal from the memory [4] or [5] or [6] passes through the terminal [B] to [C] of the switch SW-4, and passes through the video output unit [10] or [11] or [12]. The terminal [C] is supplied with the potential of + V from the terminal [A] by the addition of the own cursor signal 18-13, and is output to the video output unit as the potential of + V. Displayed as red on the monitor as a cursor.

On the other hand, the other cursor is also supplied with the other cursor signal 18-14 to the switch SW-6 which receives the output of the G signal (green signal). To the video output unit and is displayed as green on the monitor.

Therefore, according to the above embodiment of the present invention, simultaneous display of a plurality of screens becomes possible, the cursor can be effectively used, and information exchange by communication can be performed efficiently. In addition, information can be exchanged by communication in the same manner as ordinary meetings, such as changing the display position of the cursor, realizing the same display as the other one, and effectively distinguishing the two cursors by color coding, etc. A great effect can be expected on the improvement of the degree of understanding such as explanation at the time of exchanging information.

In the above-described embodiment, a specific example is described for the case where the color of the cursor is set to two colors. However, the selection range can be provided by combining each color at an arbitrary level. Of course. Although a switch is used as the cursor selection means, it can be easily realized by a mouse, a trackball, or the like.
