Abstract

An infrared video game remote control includes two LED transmitters 1 and a receiver unit 2. The transmitters each transmit an infrared pulse encoded signal at different times; the receiver unit decodes the received signals into output signals compatible with the video game. Each signal may be transmitted twice so as to reduce interference. <IMAGE>

Description

INFRARED VIDEO GAME REMOTE CONTROL SYSTEM BACKGROUND OF THE INVENTION The present invention relates to a wireless infrared video game remote control system which uses at least one infrared transmitter and an infrared receiver to control the operation of a video game system so as to reduce the possibility of data interference and improve the accuracy in data recognition.
In regular video game systems, joysticks (wired transmitters) are connected to the mainframe, and then connected to a television or a display screen for operation control. Due to the constraint of the cables, a player of a video game system should stand or sit before the television or display screen within a short distance while playing. Because the cables in a video game system are frequently stretched by players, they may be disconnected easily, causing a contact error.
SUMMARY OF THE INVENTION The present invention eliminates the aforesaid problems. It is therefore an object of the present invention to provide an infrared video game remote control system which uses infrared transmitters and an infrared receiver to control the operation of a video game system so that the players can play the video game system at distance. It is another object of the present invention to provide an infrared video game remote control system which is suitable for controlling any of a variety of video game systems by means of the operation of infrared transmitters and an infrared receiver.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figs. I and 2, an infrared video game remote control system according to the present invention is comprised of a transmitter unit 1 and a receiver unit 2. The transmitter unit 1 includes data format, decoding format, emitting time difference and control flow.
With respect to data format, please refer to Fig. 3. If any switch on either joystick is pressed, the transmitter unit sends out a respective emitting signal by means of an infrared pulse wave. The length of each emitting signal is 40 bits, which is shown by means of a pulse-duration modulation method (1 and 0 are represented by different pulse durations).
With respect to decoding format, please refer to Fig. 5. Each 40-bit emitting signal includes two identical 20-bit data to ensure a correct recognition.
Therefore, the possibility of error is as low as 1/220 = 1/1048576. As the joystick can be freely set for PLAY 1 or PLAY 2, the emitting signal for PLAY 2 is phasereversed so that the receiver unit can accurately recognize the signal for PLAY 1 from the signal for PLAY 2. That is to say that "Data 1 + Data 1" is transmitted for PLAY 1, "Data 2 + Data 2" is transmitted for PLAY 2, and "Data 1 + Data 1" is unequal to "Data 2 + Data 2". Therefore, the receiver unit can accurately recognize the received signal to be for PLAY 1 or PLAY 2.
With respect to emitting time difference, please refer to Figs. 4 and 6. If the joysticks are respectively set for PLAY 1 and PLAY 2, the infrared signal from one joystick may interfere with the infrared signal from the other as the joysticks are simultaneously controlled to emit a respective data signal. This problem is eliminated by means of emitting time difference. Because the delay times T1, T2 of PLAY 1 and PLAY 2 are variable, a synchronously continuous interference is eliminated. Therefore, the receiver unit can accurately recognize the data for PLAY 1 from the data for PLAY 2.
With respect to control flow, please refer to Fig. 7. As a switch is pressed, the respective data is encoded into a 20-bit for recognizing the state of the joystick if set at PLAY 1 or PLAY 2. If the data is recognized for PLAY 1, a corresponding data of "Data + Data" is transmitted and in which T1 = TO + RND (1) N1; if the data is recognized for PLAY 2, a corresponding data of "Data + Data" is transmitted and in which T2 = TO + RND (1) N2. After recognition, the respective data is transmitted to the receiver unit 2 through a pulse-duration modulation method.
The aforesaid transmitter unit 1 is to transmit respective data signals at a high speed and a constant frequency through a pulse-duration modulation method, and in different times for PLAY 1 and PLAY 2.
Therefore the problem of data interference is minimized.
The receiver unit 2 includes pre-amplifier, single chip CPU (or ASIC), and interface circuit.
Single chip CPU (or ASIC) continuously receives infrared pulse wave signals from pre-amplifier, and divides each batch of 40-bit data into two 20-bit data DT1 and DT2 (see Fig. 8) for recognition. In case of DT1 - DT2, it means that the received signal may be interfered and should be abandoned. A received batch of data is recognized for "Data" or "Data" only when DT1 = DT2 is checked. If DT1 is recognized pertaining to the category of "Data", it is decoded to PLAY 1; If DT1 is recognized pertaining to the category of "Data", it is decoded to PLAY 2. After the process of decoding, each 20-bit data is decoded and turned to a corresponding 16-bit data (see Fig. 9), and then sent to interface circuit for output to a video game system.
The receiver unit 2 receives PLAY 1 and PLAY 2 signals from the transmitter unit 1 at different time intervals, and therefore the possibility of data error is minimized.
