Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention provides a method for displaying a certain image on the screen of a game machine in the upper and lower directions.
The present invention relates to a data transmission method for playing a game by operating an operating unit without cables so as to freely move left and right.

(Technical Background of the Invention) Depending on the content of the game, a television game machine may use two operating means to control the image on the screen of a display device. When playing on a screen, two players simultaneously operate the images displayed on the screen and enjoy the game.

FIG. 4 shows the relationship between the game machine body and each operation means of this type of game machine which has two operation means. Rather than being directly attached, the two joysticks A' and B' are separate from the game console body 1.
and the game machine main body 1 are connected by cables 2a and 2b. Joysticks A' and B' are one of the terminals for the microcomputer, and each has a control rod for controlling the image on the display.
Then, operate it arbitrarily in the left-right direction.

Control signals obtained in response to the operation of the control rods of the joysticks A' and B' are transmitted to the game machine main body l via cables 2a and 2b, respectively, which constitute separate signal transmission paths. On the other hand, based on this input information, the microcomputer displays, for example, an image imitating the R engineer on the screen of a CRT display integrated with the game machine body 1 or separate from the game machine body 1, on the control stick. The controller is controlled in accordance with the movement, so that two players can enjoy the game on the screen using the two game joysticks A' and B'.

By the way, in a game machine that uses cables 2a and 2b shown in FIG.
Since the data is sent to the game machine main body 1 side via a and 2b, there is no data collision between them.

(Problems in the Background Art) However, when connecting two joystays 7A' and B' to the game machine main body l using cables 2a and 2b, each player's position is far from the game machine main body l. The range (distance) in which the joysticks A' and B' can be operated is restricted by the cables 2a and 2b. There are problems such as other people getting their feet caught on cables 2a and 2b located at cables 2a and 2b.
, 2b may be disconnected.

(Objective of the Invention) The object of the present invention is to be able to operate a game machine without using a cable, and to transmit data without causing an error or malfunction to the game machine even if two operation parts are operated at the same time. The objective is to provide a data transmission method that can

(Summary of the Invention) The present invention provides a receiving section in the game machine main body, performs data transmission between first and second game operation sections and the game machine main body without cables, and transmits data from each operation section. The data rate of the data sent from each operation unit is different so that even when a collision occurs, the data following the collided data can be received at least once within a predetermined time without collision. shall be.

(Embodiments of the Invention) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which two joysticks are used as operating means, and a receiver is provided on the game machine body in order to transmit data to the game machine body without cables. Infrared light is used for data transmission.

That is, in the figure, A is a transmitter equipped with a game joystick, and uses infrared rays to transmit data according to the operation of the control stick, and B is another transmitter that uses infrared rays, similar to transmitter A. With the transmitter, these and the game console body 1
There is no cable connected between the main body of the game machine l and a receiving section 3 for receiving infrared rays. The data corresponding to the joystick operation is extracted, and the subsequent processing is performed using the cable 2a in Figure 4.
, 2b using a microcomputer, similar to the game machine that uses it.

When two players play a video game using two gaming joysticks, the infrared MLJ mote control with two gaming joysticks allows cable-free operation, and each two joysticks can be operated simultaneously. In order to prevent errors and malfunctions caused by collisions of data from transmitters A and B, and to refresh the screen, even if a data collision occurs, the next data that has collided can be reliably received. Each transmission mA so that data can be received at least once within a predetermined time.
, H data rate is set.

The data format will be explained below.

Figure 2 shows the configuration of the data blower.
In this example, the data block consists of 11 bits on both transmitter A and B sides. bl is a start bit indicating the start of asynchronous serial transmission, b2 to b
9 is an information bit consisting of 8 bits, and this information bit)
bz"bl represents information about the operating direction and amount of each joystick's control column.boo is a check bit, bo is a parity bit, and in this embodiment, odd parity is used, and the number of bits representing "1" is always an odd number.

Here, specific examples of aspects of the infrared radiation for data transmission in each of the transmitters A and H, the information bits bλ to bq, etc. are as follows.

"H" = Infrared radiation (Emission) 40k
HZ"L" = No output, Information bit: Positive logic Switch ON = "H", high level means °1" state, low level means O
”, and the start bit: usually “°H”, the check bit: I=”0”, and n=“1”.

By the way, when data is transmitted to the game console side using infrared rays with this data configuration, the receiving side constantly repeats images at intervals that prevent the screen from flickering when refreshing the screen of the display device. 1760sec = 16, 6m5 for a device that must be displayed and therefore required to be refreshed within a certain time interval, e.g. 1760sec synchronization.
It is necessary to ensure that it can be received at least once during ec.

Therefore, in the method of the present invention, the data rate of each transmitter A and B is adjusted to prevent error command malfunctions when there is a collision of data from the two transmitters A and B, and to ensure screen refresh. l/of the time required for the above refresh
2 or less, and each data rate is set to be different as shown in FIG.

In other words, as shown in Fig. 1, if data is transmitted between the game machine body 1 and the game machine body 1 without cables, the player can relax at a desired position away from the game machine body 1 without being interrupted by the cable. However, in such a cableless case, unlike the case shown in Figure 4, data collisions from the two transmitters A and B will virtually always occur. . Therefore, in order to ensure that the following data is received without collision, we first change the data rates of transmitters A and H, so that even if there is a data collision, the collision will be within the above 16°6 m5ec. The data rate of each transmission fiA, H is not less than 16,6rmsec, but is 1/2 of 8, taking into account screen refresh.
, is set to 3m5ec or less.

The setting side is shown in FIG. 3, where a is the data rate (m
sec/Data), b is the data rate of transmitter B with the other gaming joystick (mse
c/Data), χ is the data block length (msec/Data) of the data structure shown in FIG. , a, and b.

a<8.3III32c* a * * 116111
111(1)b<8, 3tssec*
* * * * * e Dispute * This falls within the scope of (2). Also, χ is 0.1<χ<3! Regarding the data block length χ, which is l5ecφ−・・・−・(3), this is at the technical level,
It varies depending on cost etc.

In the case of this embodiment, L was set to 1 tssec as described later.

Regarding the point of making the data arrays a and b of each transmitter A and B different, regarding a, b and χ above, where n is an integer, nb+χ<na-...--...- (4) na+χ<
The time interval may be set to (n+1) l)e @ 11 order 1111(5), so that there is a time difference between the transmitter A side and the transmitter B side.

In this example, under the conditions described above, n=7, 2
m5ec, b=4.95m5ec, χ=l,
It was set to 1m5ec.

In this way, when playing a game on the screen using two game joysticks, data transmission between the game console body 1 and transmission @A and B can be performed without cables, as shown in Figure 3. To.

In the case of transmitter A, data with a data block length of 1 and 1a+sec is received twice within 16.6 m5 ec, and in the case of transmitter B, data is received three times. Therefore.

The screen will be refreshed reliably. Furthermore, even if there is a collision of data from transmitters A and B at different times as shown in Figure 3, the next data can be reliably received without collision, and at least 1 6 required for screen refresh
, 6+++ seconds, it is possible to ensure that the screen is refreshed.

(Effects of the Invention) According to the present invention, a receiving section is provided in the game machine main body, data is transmitted between each operation section and the game machine main body without a cable, and each data rate of the transmitted data is adjusted for each operation. Even if there is a collision of data from one part to another, the following pieces of data will not collide and will be returned within the specified time.
By varying the number of times within the range that allows reception, each player can operate a certain image on the screen of the game machine body using each operation section at a desired position away from the game machine body. Therefore, you can enjoy the game in a relaxed state, and there are no errors or malfunctions even if you operate the control panel simultaneously, and there are also problems such as getting your foot caught on the cable or the cable breaking. It also disappears.
