Embodiment
Be described below in conjunction with the embodiment of accompanying drawing to desktop sharing method of the present invention.
Fig. 1 is the desktop sharing method flow chart of an embodiment.As shown in Figure 1, desktop sharing method of the present invention can comprise the following steps:
S1, control terminal creates the extended screen spliced with the display interface of control terminal, obtains control inerface;
In this step, the extended screen being used for Desktop Share can be generated on control terminal.Fig. 2 shows the extended screen position of an embodiment.In fig. 2, system generates 3 extended screens altogether, i.e. virtual screen 1, virtual screen 2 and virtual screen 3.Wherein, virtual screen 1 and virtual screen 2 are positioned at the right side of control terminal, and virtual screen 3 is positioned at the left side of control terminal.In the present embodiment, control terminal can be notebook computer.In practical situations both, extended screen all can be arranged on the control terminal left side or all on the right of control terminal.In other embodiments, also extended screen can be generated in the upside of control terminal or downside.The quantity that the quantity of extended screen can carry out the display terminal of Desktop Share is as required determined.In fig. 2, the quantity of display terminal is 3, therefore, generates 3 extended screens; Wherein, the corresponding display terminal 1 of virtual screen 1; The corresponding display terminal 2 of virtual screen 2; The corresponding display terminal 3 of virtual screen 3.In fig. 2, display terminal is large-screen display.
After generation extended screen, the display interface of described extended screen and control terminal can be spliced, formation control interface.
In one embodiment, the step that control terminal creates the extended screen of Desktop Share comprises the resolution obtaining display terminal, and on control terminal, creates described extended screen according to described resolution.Such as, in fig. 2, suppose that the resolution of three display terminals is respectively 1680x1050,1920x1080 and 1920x1080, then the resolution of the virtual screen that each display terminal is corresponding is also respectively 1680x1050,1920x1080 and 1920x1080.Each display terminal can obtain the resolution of self, and the resolution got is sent to control terminal, and then, control terminal can be respectively each display terminal according to described resolution and generate extended screen.By obtaining the resolution of each display terminal, can generate extended screen respectively according to described resolution, thus the resolution of each extended screen is identical with corresponding display terminal, can prevents the video content shared from occurring deformation, improve impact-share, thus improve Consumer's Experience.
S2, by described display interface needing the desktop data shared move to described extended screen, gathers the desktop data of described control inerface;
In this step, desktop data control terminal needing share can be moved to described extended screen.Described desktop data can comprise desktop video data or desktop picture data etc.Control terminal can gather the desktop data of control inerface.Such as, the desktop data of speed collection control inerface that can be certain.
The step described display interface needing the desktop data shared move to described extended screen can be comprised:
Receive the shared instruction that user sends; Wherein, described shared instruction comprises the shared home position of desktop data on described display interface of needs and the target location in extended screen;
Desktop data corresponding for described home position is moved to region corresponding to described target location.
S3, carries out cutting to the extended screen of described control inerface, obtains the desktop data on extended screen, described desktop data is shared to display terminal.
In one embodiment, also can obtain the IP address of each display terminal, and the display terminal that described first desktop video data are sent to described IP address corresponding is shared.Such as, in fig. 2, suppose that the IP address of three display terminals is respectively IP1, IP2 and IP3, then each display terminal can obtain respective IP address, and the IP address got is sent to control terminal, then, the video data on extended screen can be sent to corresponding display terminal according to described IP address by control terminal respectively.Generally speaking, when control terminal needs shared video data to be sent to multiple display terminal, described IP address can be obtained; If only there is a display terminal in system, can without the need to obtaining IP address.By obtaining IP address, once different video datas can be shared to multiple display terminal, improve sharing efficiency.
In one embodiment, resolution and the IP address of display terminal can be obtained simultaneously.Still for the system shown in Fig. 2, the resolution of each control terminal and IP address can be formed the first data structure (IP1,1680x1050), (IP2,1920x1080) and (IP3,1920x1080).Then, according to the first data structure building 3 extended screens, and the second data structure (IP1,1680x1050, extended screen 1), (IP2,1920x1080, extended screen 2) and (IP3,1920x1080, extended screen 3) can be formed.
In one embodiment, suppose to have generated the second data structure in step S1, the primary importance of the extended screen that user can specify by control terminal is together with above-mentioned data structure, generate the 3rd data structure (IP1, 1680x1050, extended screen 1 position), (IP2, 1920x1080, extended screen 2 position) and (IP3, 1920x1080, extended screen 3 position), then, can according to the resolution of each extended screen and described primary importance, cutting is carried out to the described desktop video data collected in step S2, form the 4th data structure (IP1, 1680x1050, extended screen 1 desktop video), (IP2, 1920x1080, extended screen 2 desktop video) and (IP3, 1920x1080, extended screen 3 desktop video).
Finally, described first desktop video data can be sent to display terminal and share by control terminal.Such as, suppose to define the 4th data structure, control terminal according to IP address number, can call 3 video encoders simultaneously and compresses 3 extended screen desktop videos respectively.After compression, form the 5th data structure (IP1,1680x1050, compressed video stream 1), (IP2,1920x1080, compressed video stream 2) and (IP3,1920x1080, compressed video stream 3), according to different IP, compressed video stream is mail to each control terminal.
Display terminal, after the compressed video stream receiving control terminal transmission, can be decoded to described compressed video stream, and be shown by decoded video.
In addition, the step described desktop data being shared to display terminal also can comprise:
Detect user to the operation of described desktop data;
Judge whether the region at the object place of described operation is positioned at extended screen;
If so, described operation is shared to described display terminal.
Described desktop sharing method has the following advantages:
(1) only the video data in extended screen can be shared to display terminal, and by all videos data sharing of control terminal to display terminal, the fail safe of Desktop Share can not be improve.
(2) there is deformation when display terminal shows in the video that can prevent control terminal from sending, improves Desktop Share effect.
(3) once different video datas can be shared to multiple display terminal, sharing efficiency is high.
