Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication base terminal device for communicating between terminals using a television receiver through a communication line such as a telephone line.

In the past, the only way to carry out remote gatherings was by mail or telegram, and when using the telephone, the only way was to announce each other's starting position aloud while holding the receiver in hand.

As a result, complicated operations were required and communication took a long time, making it impossible to perform a sufficiently satisfactory encircling operation.

The present invention is a four-base terminal device that uses a broadcast television receiver, which is already widespread in most homes, as a display device. It's about getting used to it.

The drawings will be explained in detail below.

FIG. 1 shows an embodiment of the invention.

A synchronization control circuit 102 generates all signals necessary for synchronization using a clock 101 signal.

The base item generation circuit 1 is activated by a signal from the synchronous control circuit 102.
03 produces black base grains as shown by thick lines in FIG.

On the other hand, the background signal circuit 104 also has a white stone substrate.
A signal is generated to make pixels that do not display a black stone pattern gray (halftone between black and white).

On the other hand, the white stones and black stones that have been started are displayed using a method similar to the rask scanning type character display method.

That is, as shown by thin lines in FIG. 2, the television screen is virtually divided into 19×19 areas, and each area is regarded as a character in a character display.

At this time, the substrate eye generation circuit 1 is placed approximately in the center of each area.
03 so that the intersection of the base grain patterns generated from 03 is located.

The refresh memory 105 has memory cells corresponding to this 19×19 area, and stores information to be displayed there.

In this case, one of the three states of no display, white stone, and black stone is stored.

This refresh memory 105 uses a signal from the synchronization control circuit 102 to store the information in the memory cells corresponding to the 19 areas on the scanning line currently being horizontally scanned before the first scanning line that reaches that state in each field. Load into line memory 106.

The line memory 106 receives signals from the synchronous control circuit 102 at the time of division of the 19 areas, counts the number in the horizontal direction, takes out the information in the corresponding memory cell, and generates a pattern through the blinking control circuit 107. Pass to circuit 108.

For example, if the area has 12 pixels in both the horizontal and vertical directions, the line memory 106 has 12 horizontal scanning lines.
This operation is repeated until the number of times is counted, and then the information corresponding to the next 19 areas is refreshed in memory 1.
Receive from 05 and start the same operation again.

The blinking control circuit 107 stores the address of the area to be blinked (information specifying one of the above 19x19 areas), and when the information corresponding to that area comes from the line memory 106, the blinking control circuit 107 stores the address of the area to be blinked (information specifying one of the 19x19 areas mentioned above), and when information corresponding to that area comes from the line memory 106, the blinking control circuit 107 performs blinking once every two fields. Alternatively, for the next two fields in succession, the information is inhibited and the information is not passed to the bang generation circuit 108.

Then, that part of the television screen will flicker more than other parts, creating a blinking effect.

On the other hand, the cursor signal is generated by the cursor generation circuit 110 so as to overlap the intersection point of the base line at the center of the area specified by the cursor address generation circuit 109.

The situation is shown in Figure 3, for example.

In other words, the gray background A on the television screen and the base B
is displayed in black, but cursor C is displayed in white as a combination of a horizontal cursor and a vertical cursor, superimposed on the base.

In that part, the white cursor wins, so it looks like the base eye has disappeared.

In this way, when several signals overlap on one pixel, the video signal creation circuit 111 controls which one to take and creates a video signal.

Here, as shown in Figure 1, the cursor signal is given top priority and set to white, then the white or black stone pattern is set to white or black as instructed, then the base signal is set to black, and if the above three signals are not present, Create a video signal to make the background signal gray.

The priority order here means that the signal with the highest priority existing for each pixel is output and the others are inhibited, and it is clear that this can be easily constructed using a known circuit.

The television signal creation circuit 113 adds the video signal to the decoded synchronization signal created by the decoded synchronization signal creation circuit 112 to create a television signal.

Go is first played by pressing the initial setting switch 114 to clear the refresh memory 105 and the like.

Next, if it is on the black side, operate the rotary switch 115 to move the cursor to determine the place where you want to start.

The cursor input control circuit 116 is connected to this rotary switch 11.
5 and reads the movement of the input address generating circuit 109.
give it to

The rotary switch can also be a thumbwheel or joystick known from graphic displays, or it can be a variohm or a simple rotary switch.

When the cursor is displayed at the address generated in this way, if the address is correct, the operator can operate the start switch 117 to express his intention to start.

Then, the start determination circuit 118 starts the memory read/write control circuit 11.
9 to read the information of the memory cell in the refresh memory 105 corresponding to the cursor address.

If it is in a non-start state, the start determination circuit 118 determines that it is a new move, and instructs the memory read/write control circuit 119 to display a "black stone" at the cursor address position through the move generation A circuit 120. .

Then, that information is written into the corresponding memory cell of refresh memory 105.

At the same time, the start determination circuit 118 notifies the blinking control circuit 107 that the current cursor address should be blinked, and the cursor address 19
Information indicating one of the areas of X19 is stored.

If the blinking is correct, the player confirms by switching 1
21 confirms that it will be undertaken.

Then, the start determination circuit 118 activates the blinking control circuit 10.
7 to clear the currently stored address.

Note that this confirmation switch 121 is the same as the start switch, and can also be used as a two-step push-in switch, with the first step being used to confirm the start and the second step being used to confirm the start.

It is also possible to cancel the confirmation itself and display it without blinking in one move.

At this time, the blinking control circuit 107 becomes unnecessary and the line memory 106 is directly connected to the bang generation circuit 108.

If the starting position has already been started,
If it is the opponent's stone, the move determination circuit 118 considers it to be a raised stone, and instructs the memory read/write control circuit 119 through the move generation A circuit 120 to place that part in a non-moved state.

At the same time, the black side of the raised stone counter 122 is ordered to be increased by +1.

The contents of this raised stone counter 122 can also be displayed numerically outside of the base number, but this method is already known.
This can be solved by slightly increasing the number of memory cells in the refresh memory 105 and line memory 106.

However, the bang generation circuit 108 also has a number pattern.

If the stone that is moved is the player's own stone, it is interpreted as "waiting" and the player simply performs blinking.

Once confirmed, the area is returned to a non-starting state.

The confirmed move is then transmitted to the other party through the transmission control circuit 123 along with address information and information on whether the move is a new move, a new move, or a waiting move.

The information sent from the other party is received by the transmission control circuit 123, and the address is sent to the address generation circuit 124.
The classification information of ``age stone'' and ``wait'' is passed to the move generation circuit 8 125.

The subsequent rewriting of the refresh memory 105 is the same as described above, so the explanation will be omitted, but if it is just a raised stone, it is passed to the raised stone counter 122 and the counter on the white side is incremented by 1.

The game of Go is played in this way, but it will be clear from the above explanation that black and white can also be reversed.

Next, the base item generation circuit 103 is configured as shown in FIG.

That is, 301 is a 1/12 power countdown circuit, 30

That is, in FIG. 4, the 1/12 power countdown circuit 301 counts down this frequency and produces an output et 111 every 12 pixels, ie, every time interval of the vertical line of the substrate.

This output is applied to the vertical and horizontal line generation circuit 304 to create the clock position for vertical line generation.

In addition, the clock counted down by 1/12 in the 1/12 power count down circuit 301 is applied to the 1/30 power count down circuit 302 to output a pulse in a 30 unit pattern, that is, every horizontal scanning line. Assume that 30 units of pattern time are allocated to the time.

This output pulse is applied to a 1/12 force count down circuit 303 which provides an output pulse every 12 horizontal scan lines, ie every horizontal line of the board.

This output is applied to the vertical and horizontal line generation circuit 304, which indicates the clock position of horizontal line generation.The vertical and horizontal line generation circuit 304 is an OR circuit, and when either input takes "1" indicating a black line, the output is '1'.

25 force is applied to the countdown circuit 305 and the horizontal scan line 5
Output is output every 25 lines, that is, every frame.

This output is applied to frame detection circuit 306 to detect the end of the frame.

Also, the output from this circuit 306 is used to reset other counters.

Further, the output of the 1/12 force countdown circuit 301 is applied to the vertical frame setting circuit 307, and this circuit counts the number of unit patterns from the horizontal scanning start point to determine the unit pattern position P1 of one horizontal scanning line.

(n-1 to 19) and P2O, n(n-1 to 19)

The gate circuit 310 is a two-manufactured AND circuit that receives outputs from the vertical frame setting circuit 307 and the horizontal frame setting circuit 308, and creates a base figure signal when both outputs are +1111.

Counter circuits 311 and 312 are respectively circuits that perform control to erase the black line portion on the outer periphery within the base frame.

The counter circuit 311 detects the left edge of the board in the vertical frame setting circuit 307, starts counting the pixel clock, and outputs a clock for 6 pixels, that is, erases the horizontal black line 21 by half of the width of the unit pattern (12 pixels). The gate circuit 3

Similarly, an instruction to erase the horizontal black line 22 at the right edge of the board is also given.

The counter circuit 212 detects the upper edge of the board with the horizontal frame setting circuit 308, and then uses the 1/30 force count down circuit 302.
It starts counting the number of scanning lines starting from (') and sends an instruction to the gate circuit 309 to erase six vertical black lines, that is, half of the vertical width (12 pixels) of the unit pattern.

Similarly, the lower vertical black line can also be erased.

The gate circuit 309 is an AND circuit operated by three people, and outputs an output 11191 only when there is a black line instruction from the vertical and horizontal line generation circuit 304 and an instruction from the counter circuits 311 and 312 that the period is a black line display period. Generate a signal.

Next, the bang generating circuit 108 is constructed as shown in FIG.

OM), 503 is a parallel-to-serial conversion circuit.

That is, the stone code corresponding to each grid point is input to the decoder circuit 501.

Next, in accordance with the clock, the dot pattern in the ROM 502 is read out for each necessary row at that time and input into the parallel-to-serial conversion circuit 503.

After that, it is converted into a serial signal and a stone pattern television signal is created by pattern switching.

As explained above, it is now possible to play a game of Souki via a communication line using a home television receiver, and unlike mail, telegrams, and telephones, you can enjoy Souki without complicated operations.

In the embodiment shown in FIG. 1, the baseband television signal created by the television signal creation circuit 113 is directly converted to VT.
It can be connected to the R terminal.

If the receiver does not have a VTR terminal, it is sufficient to modulate it with VHF and direct it to the antenna terminal.
