A kind of interactive network video conferencing system
Technical field
The utility model relates to a kind of video conference device, especially relates to a kind of interactive network video conferencing system.
Background technology
The network teleconference is all-pervasive: the architect describes the concept of following green building; Explanation is annotated and commented on to drawing in the mapping center; The doctor explains diagnostic result or flow process to the patient; Student and strange land classmate put the axe in the helve jointly; The advertising manager discusses story intention and layout; Enterprise is used for application such as training and education.The form of local computing picture by double fluid can be sent to the other side by network teleconference system.The mode of this teaching, training is that traditional passive type is accepted.Can't realize interactive and long-range modification and the annotations and comments of two-way mutual.And on academy of design, remote teaching and distance medical diagnosis, need both sides to send the computer picture of training double fluid, carry out modification and the discussion of remote switch formula.This has proposed reform trend to current network video conferencing system training method.The video conference training need realize the application of interactively computer double fluid.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of to realize that interactive double fluid is used, interactive network video conferencing system simple in structure in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of interactive network video conferencing system comprises a plurality of video conference terminals, is connected with touch blank assembly on the described video conference terminal.
Described touch blank assembly comprises electronic whiteboard and blank special pens.
Described video conference terminal is provided with expansion USB mouth, and described electronic whiteboard is connected with video terminal by this expansion USB mouth.
Described a plurality of video conference terminal interconnects by network.
Compared with prior art, the utlity model has following advantage:
1) the utility model is realized the two-way interaction of video conferencing system by touch blank assembly;
2) the utility model is widely used, as long as possess the USB interface of expansion, connects electronic whiteboard, can realize remotely modifying and the annotations and comments of video conference.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of interactive network video conferencing system comprises a plurality of video conference terminals 1, is connected with touch blank assembly 2 on the described video conference terminal.Described touch blank assembly 2 comprises electronic whiteboard and blank special pens.Described video conference terminal 1 is provided with expansion USB mouth, and described electronics is connected with video terminal by this expansion USB mouth from plate.Described a plurality of video conference terminal 1 interconnects by network.
By above-mentioned interactive network video conferencing system, can be with the local computing picture by double-current application technology, with long-range the sharing to the other side of the computer picture of this locality.Content the other side of local computing picture modification can be high-visible, also can annotate and comment on and revise by touch blank assembly controversial the other side, both sides are open to discussion and that revise, and mode is finished final final version, realizes the application of the interactive double fluid of video conferencing system training.
