A kind of interactive data for remote video system is shared and display systems
Technical field
The utility model relates to a kind of remote video system, especially relates to a kind of interactive data for remote video system and shares and display systems.
Background technology
Network teleconference system is as a kind of typical case of Multimedia session type communication service, and video conference business has been brought into play huge channeling in social information interchange.Video conference couples together the multimedia conferencing terminal in two or more places by communication network, transmits various images, speech and data-signal betwixt, the sensation that the person of attending a meeting is had be in the action.Except being used for the multiple spot multimedia conferencing, video conferencing system also is applied to the business that long-distance education, tele-medicine etc. need to transmit real-time audio, video and data.
Continuous progress along with network technology, and the fast development of video signal technology, the realization in network of sound, video technique has become day by day light, and especially outstanding is under good product support, and based on network video conference application will become the important component part of multi-service working environment.But when using traditional video conference means to carry out meeting, only PPT or data can be sent to far-end by the second road stream, but also can only remind by the slip of language or mouse for the emphasis part of some data, under such mode, there is very big problem in the efficient of linking up
The utility model content
The purpose of this utility model is exactly to provide a kind of interactive data for remote video system to share and display systems for the defective that overcomes above-mentioned prior art existence, can in video conference, carry out the annotations and comments of some necessity by this system, the place that needs emphasis to note can more significantly mark, and makes to link up to have more efficient.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of interactive data for remote video system is shared and display systems, this system comprises communication network and a plurality of video conference terminal, described a plurality of video conference terminal interconnects by communication network, this system also comprises a plurality of for the data display touch-screen that video data is annotated and commented on, and each video conference terminal is connected with at least one data display touch-screen.
Described video conference terminal comprises for the output equipment that shows the far-end audio, video data, for the input equipment that obtains local audio, video data, is used for audio, video data is carried out the processor of encoding and decoding processing and the access device that is used for the access communications network, and described output equipment, input equipment and access device are connected processor respectively.
Described video conference terminal is connected by the high definition cable with the data display touch-screen.
Compared with prior art, the utlity model has following advantage:
1, carry out the coding processing of audio frequency and video by professional dsp processor, system's line is simple, and configuration is convenient, can reach the video effect of 1080P30 frame, guarantees the face-to-face communication effectiveness of meeting.
2, audio-video signal is gathered synchronously and is encoded, fully synchronous signal.
3, the data display touch-screen is connected to video conference terminal by the high definition cable, video conference terminal adopts double-current technology, when the image effect above the data display touch-screen is sent to far-end, can carry out the operation of various annotations and comments and emphasis mark at the data display touch-screen, also share to far-end simultaneously, improve the communication efficient of meeting.
4, control is simple, and easy to use, few in the later maintenance workload, work load reduces a staff.
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 data for remote video system is shared and display systems, and this system comprises communication network 3, at least two video conference terminals 1 and data display touch-screen 2.Interconnect by communication network 3 between the video conference terminal 1, adopt double-current technology between the video conference terminal 1, simultaneously the transmitting two paths data flow.
Each video conference terminal 1 comprises for the output equipment that shows the far-end audio, video data, for the input equipment that obtains local audio, video data, is used for audio, video data is carried out the processor of encoding and decoding processing and the access device that is used for the access communications network, and output equipment, input equipment and access device are connected processor respectively.Wherein, the processor adopting dsp processor carries out the coding of audio frequency and video to be handled, and system's line is simple, and configuration is convenient, can reach the video effect of 1080P, 30 frames, guarantees the face-to-face communication effectiveness of meeting.
Each video conference terminal 1 is connected with at least one data display touch-screen 2, and data display touch-screen 2 carries out transfer of data with video conference terminal 1 by the high definition cable, guarantees the quality of picture.Data display touch-screen 2 can exchange the operation that data are carried out various annotations and comments and emphasis mark to PPT or other, improves the communication efficient of meeting.
This system specifically can be achieved as follows function:
1, video conference
By video conference terminal both sides' image and sound are transmitted by network, simultaneously, the audio frequency and video effect of high definition can allow both sides' communication have more efficient.
2, double-current meeting
When sending meeting field picture harmony sound, also can or exchange data sync with PPT and send to far-end, reach the effect that transmits the two-way high definition video steaming simultaneously.
3, long-range annotations and comments
When carrying out double fluid, transmit leg can carry out real-time annotations and comments or emphasis mark on the image of double fluid, and the user of far-end also can see shared annotations and comments by video conference terminal.
