The computer control system based on the WHDI is characterized in that the computer is connected with the transmitter through a universal serial bus (USB) interface, the receiver is connected with a USB HUB through a USB interface and the USB HUB is connected with a plurality of peripheral USB equipment which is used for controlling the computer. The computer control system based on the WHDI ensures that the receiver end can remotely control the computer which is connected with the transmitter end.
Description
Technical field
The utility model relates to the Computer Applied Technology field, particularly a kind of computer control system based on WHDI.
Background technology
So far, WHDI (WirelessHD system) is media with the radiowave, the channel that adopts 5GHz must not authorize, 1080P (not having compression) high definition resolution signal and stereophonic signal are transmitted 30 meters scope, and can easily penetrate the obstruct of wall, and with HDMI (High Definition Multimedia Interface) (High Definition Multimedia Interface, HDMI) video transmission time-delay is controlled in 1 millisecond, makes home audio-visual center and multimedia conferencing demonstration center easily set up.The connection configuration of equipment is very simple, be equipped with transmitter and receiver, all information sources send full HD format video and binary channels form stereo audio, subsidiary telepilot can choose at random the input channel circuit, and support multiplex infrared remote control retransmission function, the computing machine that is suitable for high definition projector, blue-ray DVD, HTPC, high definition set-top box, XBOX360, PS3, WII and has audio/video output.
Yet the data message of above-mentioned prior art transmission has following problem: can only the one-way transmission video and audio signal based on the transmitter of WHDI technology and receiver, and bi-directional data only transmits simple CEC information and HDCP verify data.So can not can only watch and listen to the video and the audio frequency of emitter terminals computing machine at the computing machine of receiver end Long-distance Control emitter terminals connection based on existing WHDI technology.
The utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is: the computing machine that connects in receiver end Long-distance Control emitter terminals how.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of computer control system based on WHDI, comprise: computing machine, the transmitter, the receiver that are connected with described computing machine by HDMI, the display and the loudspeaker that are connected with described receiver by HDMI, also connect between described computing machine and the transmitter by USB interface, described receiver also connects USB HUB by USB interface, and described USB HUB connects the some external USB equipment that are used to control described computing machine.
Wherein, described external USB equipment comprises touch-screen, and described touch-screen connects USB HUB by USB interface.
Wherein, described external USB equipment comprises mouse, and described MouseAcross is crossed USB interface and connected USB HUB.
Wherein, described external USB equipment comprises keyboard, and described keyboard connects USB HUB by USB interface.
(3) beneficial effect
The utility model connects by USB interface between computing machine and the transmitter by connect USB HUB at receiver, connects peripheral hardware by USB HUB, makes the computing machine that receiver end can the Long-distance Control emitter terminals connects.
Description of drawings
Fig. 1 is a kind of computer control system synoptic diagram based on WHDI of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of computer control system synoptic diagram for the utility model embodiment based on WHDI, comprise: computing machine, the transmitter, the receiver that are connected with computing machine by HDMI, the display and the loudspeaker that are connected with receiver by HDMI, also connect between computing machine and the transmitter by USB interface, receiver also connects USBHUB by USB interface, and USB HUB connects the some external USB equipment that are used to control described computing machine.External USB equipment comprises touch-screen, mouse, keyboard etc.Wherein, touch-screen, mouse, keyboard all connect USB HUB by USB interface.
Principle of the present utility model and workflow are as follows:
The receiver based on WHDI in the utility model has USB HOST function, and transmitter has USB DEV function.Unique " root " is arranged in the topological structure of usb bus, and this root is exactly USB HOST (usb host), all USB device by USB HUB or directly and USB HOST couple together, the USB device here is exactly USB DEV.
Receiver is connected to external USB equipment in the computing machine with USB HOST function by transmitter.Receiver has USB HOST function, and in the time of USBHUB that USB device is inserted, the USB interface chip changes according to bus level and produces hardware interrupts, informs that the USB computing machine has new equipment to be connected on the usb bus.The process that detects the new equipment insertion sends the order that has USB device to connect with receiver to transmitter and realizes in WHDI.Transmitter receipt, is promptly simulated USB device and is connected to computing machine by enabling the connection status of USB functional simulation USB device to described order back.
After the simulation USB device is connected to computing machine, receiver and transmitter by the mutual data of WHDI transmission channel computing machine and USB device (referring to patented claim: 201110048820.4), realize of the control of external USB equipment to computing machine, as: utilize touch-screen to come control computer.
After control was finished, the USB device disconnection was connected with USB HUB's.Similar when being connected with USB, receiver sends the order that USB disconnects to transmitter; Transmitter receipt, is promptly simulated USB device and is connected with described main frame disconnection by forbidding the state that removes of USB functional simulation USB device to described order back.
Above embodiment only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
Claims (4)
1. computer control system based on WHDI, comprise: computing machine, the transmitter, the receiver that are connected with described computing machine by HDMI, the display and the loudspeaker that are connected with described receiver by HDMI, it is characterized in that, also connect between described computing machine and the transmitter by USB interface, described receiver also connects USB HUB by USB interface, and described USBHUB connects the some external USB equipment that are used to control described computing machine.
