Embodiment Construction

[0021] The detailed structure of the present invention, application principle, function and effect, refer to the appended Figure 1-2 , which will be described through the following embodiments.

[0022] The USB wireless expansion system uses the WHDI control channel to realize the data transparent transmission function of the USB device. It is composed of a receiving device (RX end) and a transmitting device (TX end). The RX identifies the external USB device inserted by the user, and through the WHDI wireless control channel ( Consisting of WHDI wireless transceiver module A, WHDI wireless transceiver module B and wireless channel) notify the TX end, the TX end simulates the corresponding USB device, when the user USB device sends data, RX is sent to TX through the WHDI control channel, and TX simulates The corresponding USB device sends corresponding data to the terminal (PC, game machine, etc.), so that the user can use the corresponding USB device on the display.

Abstract

The invention provides a USB (Universal Serial Bus) wireless extension system, relates to the technical field of electron and aims at solving the technical problems that the traditional USB wireless extension system mainly does not support a unvarnished transmission function of a USB HID (Human Interface Device) device and has short wireless transmission distance; an HID device is not universal, a single receiver does not support multidevice simultaneous reception, and the like. The USB wireless extension system comprises a receiving device, a transmitting device and a WHDI (Wireless High Definition Interface) wireless control transmission channel, wherein the WHDI wireless control transmission channel comprises a WHDI wireless transmit-receive module A, a WHDI wireless transmit-receive module B and a wireless channel, wherein the wireless channel is used for connecting the WHDI wireless transmit-receive modules A and B, the output end of the receiving device is connected with the input end of the WHDI wireless transmit-receive module A, the input end of the receiving device is connected with the output end of an external USB device, the input end of the transmitting device is connected with the output end of the WHDI wireless transmit-receive module B, and the input end of the transmitting device is connected with a terminal device. The invention is suitable for designing the USB wireless extension system.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a wireless extension system for wireless high-definition devices and other devices requiring USB HID. Background technique [0002] The current WHDI wireless high-definition devices on the market do not support the transparent transmission function of USB HID devices, which limits the application of WHDI in the market of interactive devices such as computers and game consoles. Usually, interactive devices need to be connected to USB HID devices such as USB mice, keyboards, and joysticks. , and currently there is no such product on the market. [0003] Wireless devices such as wireless keyboards and mice with similar functions currently on the market have a short communication distance of only about 9 meters, which cannot meet the application requirements of long wireless transmission. [0004] Because HID devices are not universal, wireless keyboards and wireless mice curren...
