The HID events that HID input equipments are produced.Screening and filtering is carried out to produced HID events, by the HID events after screening and filtering
Send to the distance host.Corresponding operating is performed according to the HID events for receiving in order to the distance host.In this enforcement
In example, the display interface of the local host is shown especially by the output display unit, and in the aobvious of the local host
Divide in showing interface and specify display window.After gathered video signal is received, show in the specified display window
The corresponding picture of video signal for being gathered.
Wherein it is possible to according to the HID events, determine that the user of the local host is existed by the HID input equipments
The position operated in the display interface of the local host.Whether specified aobvious by described in the position operated described in detection
Show that window is captured.If so, the HID events are then retained.If it is not, then filter the HID events, and by the local host according to
The HID events perform corresponding operating.For example：Local host obtains distance host display picture by video acquisition.When local
After the application layer of main frame receives local HID events, local host is by the HID events such as local mouse-keyboard according to event target
Host filters, and judges whether to need the event forwarding to distance host according to current focus window, if it is desired, then by the thing
Part is by hid gadget device forwards to distance host.Wherein, HID events can be specifically key mouse event, and key mouse event can
To be interpreted as user when local host is operated on local host by the HID input equipments such as keyboard, mouse, this landlord
Machine generates corresponding key mouse event as HID events according to the operation of user.If HID input equipments be touch screen, rocking bar etc. its
His input equipment, then local host can also be using corresponding existing means generation HID events.
And local host can judge whether to need for the event forwarding to work as Mus to distance host according to current focus window
Mark and KeyEvent are captured by the window, will be processed by local host.When mouse and KeyEvent are captured by the window, it will quilt
It is transmitted to distance host to be processed, so as to realize remotely control.The control to distance host is realized so as to pass through HID event forwardings
System.After filtering so as to the control course of event software for producing the HID devices such as mouse-keyboard, directly it is transmitted to remotely by USB
Main frame, it is to avoid control time delay of the event in network transmission process, improves the real-time responsiveness of remotely control.To picture
Prescription is higher, under the limited application scenarios of the network bandwidth, can realize efficiently control remote host in real time.
Each embodiment in this specification is described by the way of progressive, identical similar portion between each embodiment
Divide mutually referring to what each embodiment was stressed is the difference with other embodiment.Especially for equipment reality
For applying example, as which is substantially similar to embodiment of the method, so describing fairly simple, related part is referring to embodiment of the method
Part explanation.The above, specific embodiment only of the present utility model, but protection domain of the present utility model is simultaneously
