The game peripheral device transmits the analog signal of the command to the game host ^ through the signal transmission line 15 immediately, but the signal transmission line 15* only accommodates the occupation, and the use distance of the peripheral device 丨3 is limited by the length of the signal transmission line 15. . As shown in Figure 2, the game console 12i and the game peripherals can also be borrowed! The two infrared receivers 121 and the infrared emitters 131 reach the command function, but the receiving angle of the infrared receiver 121 is limited to 20 degrees, and will block the object (table lamp or stand, etc.) and cause the separation 1305728 The rate of infrared transmission (丨丨5.2Kbps~丨6Mbps) is interrupted or dead angle. In addition, the distance is also limited, so the game's handling is very good.

In particular, many interactive wireless gaming devices require the use of a non-contact pointing device to provide the player with control over a particular object or object in the television display. This type of pointing device can emit infrared light to direct the movement of objects or cursors on the screen. In fact, there is a game peripheral device with an action tracking sensor ((10) "on tracking sensor") which is disposed on the screen end of the display screen.

Therefore, the motion tracking sensor receives the continuous dot pattern of the infrared movement. Therefore, the game peripheral device can compare the dot pattern to the corresponding coordinates in each screen, and immediately notify the game host to change the television screen. The position of the object or the cursor. The traditional game peripheral device and the game console face such a large amount of data transmission needs, can not be satisfied by infrared transmission 'more importantly, can balance the convenience of operation. In summary, the conventional signal transmission line And the infrared transmission wheel can not meet the convenience of the player, and the limited transmission speed of the command also causes the continuous motion command to be transmitted instantaneously and quickly. Therefore, the operation and application of the conventional electronic game device cannot satisfy the continuous enrichment.

It is a conversion signal that conforms to the ultra-wideband specification and is output accordingly. Therefore, the wireless signal built in or external to the game 5.3 series standard and the wireless serial bus interface module can be double-converted to comply with the IEEE802.1 universal serial bus signal. [Embodiment] The over-frequency technology is ^ in the frequency band, through the pulse signal transmission technology, and (4) in the field of wireless communication.

For example, the ultra-wideband signal ^ has a frequency of 4 GHz and a relative bandwidth of at least 1. Because the pulse signal takes a very short time in the time domain (tlme d〇main), there is a very large bandwidth in the frequency domain. In addition to the use of single-band pulse signals, there are techniques for multi-band operation that divide the entire bandwidth of an ultra-wideband system into multiple small bands, which in the spectrum are presented in multiple bands. According to Shannon's maximum channel capacity (Maximal Channel)

CapaCUy) Formula: Transmission rate = frequency band xlog2(S/N), where S is the nickname power and N is the noise power, and the transmission rate will increase linearly with the increase of the used frequency band.
