Embodiment
For solve adopt in the conventional art remote controller to video conference terminal control bring can't cover video conference all functions, unhandy problem, the utility model proposes a kind of visual control system based on video conference terminal, can carry out long-range, visualized operation to video conference terminal.
As shown in Figure 1, this system is made up of video conference terminal and visual control terminal; Wherein, video conference terminal comprises first signal transmitting module, screen scraping module, compressed/encoded module, video conferencing system processing module, first signal receiving module and signal resolution module; Described first signal receiving module connects the video conferencing system processing module by signal resolution module; Described video conferencing system processing module connects first signal transmitting module by screen scraping module and compressed encoding module; Described visual control terminal comprises secondary signal receiver module, decompressed/decoded module, visual interactive module, signal package module and secondary signal sending module; Described secondary signal receiver module connects visual interactive module by the decompressed/decoded module; Described visual interactive module connects the secondary signal sending module by the signal package module.
The operation principle of this system is:
When visual control terminal starts, automatically video conference terminal is searched in search, behind the video conference terminal device in searching the wireless signal scope, initiate to connect to this video conference terminal, for guaranteeing being connected one to one between visual control terminal and the video conference terminal, visual control terminal need send privately owned connection key to video conference terminal, the connection password that connects string and carry out generating after the md5 encryption that this privately owned connection key generates for the hardware information according to video conference terminal, by video conference terminal this connection password is authenticated, because this password is the unique identification of video conference terminal, all video conference terminals can not repeat, after authenticating, can guarantee being connected one to one of visual control terminal and video conference terminal;
For the connected mode between visual control terminal and the video conference terminal, in order not influence layout, to save cost, generally all adopt wireless connections, for example: modes such as 2.4G WIFI or 5G WIFI, can change selection according to user's request;
At video conference terminal, grasped by the screen display content of screen scraping module to terminal, generate picture, by the compressed/encoded module picture is compressed, encodes, encapsulates then, form packet and submit to first signal transmitting module, first signal transmitting module sends to packet the secondary signal receiver module of visual control terminal by wireless network; Need to prove that the screen scraping module disposes according to user's request the extracting frequency of the screen display content of terminal, it grasps frame per second and can adjust according to the height of video conference terminal performance, is defaulted as a fixing frame per second; And for compressed encoding, can directly adopt existing technology, comprising: coded systems such as H264, MPEG4 also comprise HG264 coded system that flies to look U.S. in the video conferencing system etc.;
At visual control terminal, after receiving the data that video conference terminal sends, the secondary signal receiver module resolves, data after resolving are submitted to the decompressed/decoded module decompresses accordingly, decode operation, data are reduced to the video flowing that can present, again this video flowing are submitted to visual interactive module; Need to prove that the decompressed/decoded module adopts and the mode corresponding to this data coded system the decoding of data; And for visual interactive module, it comprises and can present and assemblies such as the touch-screen of touch operation, event getter, the display data on the screen of the video conference terminal after being respectively applied to present through decoding, decompressing, and obtain the Action Events that the user carries out at visual control terminal; This Action Events comprises: mouse event, KeyEvent, touch-control event etc. respond by these Action Events are presented it in visual interactive module, thereby realize user's all operations is monitored;
Event getter in the visual interactive module is after getting access to Action Events, Action Events is packaged into the signal bag passes to the secondary signal sending module, the secondary signal sending module sends to described signal bag by the wireless network between video conference terminal and the visual control terminal first signal receiving module of video conference terminal, first signal receiving module of video conference terminal passes to signal resolution module with it after receiving the signal bag, signal resolution module is resolved packet and is reduced to Action Events, again Action Events is passed to the video conferencing system processing module and carry out corresponding operation, realize the operation control to video conference;
Interaction flow between the above video conference terminal and the visual control terminal is a single-cycle event action, in actual applications, screen scraping module in the video conference terminal uninterruptedly grasps screen picture, and the screen of the visual control terminal of real-time update, realize the synchronous of screen-picture; Visual control terminal is also operated the user control message continuously and is sent to video conference terminal, respond execution, thereby make the user finish real-time operation and response at visual control terminal, so In the view of the user, the picture of video conference terminal is synchronous with the picture maintenance of remote control terminal all the time;
And the utility model has also kept the origin operation function to video conference terminal, namely can operate simultaneously video conference terminal and visual control terminal, and not conflict mutually of operation.
To sum up, the utility model can avoid adopting mouse, keyboard directly to the complex operations of video conference terminal control, also solved the limitation problem of using Digiplex in the conventional art, utilize visual control terminal to realize Long-distance Control to video conference terminal quickly and easily, with respect to conventional art, the application's beneficial effect can be summarized as follows:
1), can control video conferencing system fully by the mode of Long-distance Control, all functions operation of realization video conferencing system.
2), solved under the situation that meeting room is big or number is more, need interrupt speaker's situation when the host operates.
3), when solution conventional mouse keyboard operation distance is limited, solved the limited problem of traditional remote controller operating function again.
4), having solved the collaborative and data sharing module of office traditional in the video conference can't be by the problem of remote controller Long-distance Control.
5), solved the problem that the user experienced during remote controller was held a meeting, for the user brings brand-new visible wireless control.
