Video conferencing and interactive whiteboard combined use of the program – vide
In the traditional video conference, to data transfer, you must add a Shuangliu module, with the dual stream functions, the other party can see the local PC, PPT, WORD and other data files, but this data is a single to and can only send one end, one end of the watch, for some design class customer base, they also hope to have a way to make changes to documents the two sides discussed the function, dual stream feature the views of the meeting can not meet the requirements of this interaction.
Shanghai China, as the technology for this situation, the proposed video conferencing and interactive Whiteboard Combination programs. The program is very simple to use interactive electronic White Board Shuangliu modules can be alternative.
The following two video conferencing systems to POLYCOM for example, this system is mainly POLYCOM video conferencing terminals and two hung together two interactive whiteboards and client. The main venue in the overflow and all through the router, video conferencing and interactive whiteboard to assign an IP address of the system, when connected, the main venue for video conference video conferencing site with sub-IP connected to the main venue whiteboard whiteboard system connected to the system with sub-venues. In fact this system can be understood as video conferencing and interactive whiteboard are two separate systems.
Major advantage of this system is reflected in Hong powerful interactive whiteboard together, the following us on this program with the tradition of double session to make a simple comparison:
1. Image quality As two different ways to transfer data, interactive whiteboard picture transmission module is better than dual stream transmission of the picture effect, this is what we confirmed after several tests.
2. Network bandwidth Shuangliu module transmit data, video conferencing will take up half the bandwidth, if the video conferencing bandwidth 384K, plus dual stream module if the data transfer bandwidth occupied 192K, video conferencing bandwidth of only 192K, which is possible because enough bandwidth, packet loss will be severe, resulting in picture freeze, not smooth, not clear and so on;
The interactive whiteboard can resolve this problem, Hong combined interactive whiteboard can be used independently, and just now we are also introduced to the program, its use of bandwidth is not independent of any relationship with the video conference, So he would not take up bandwidth, can achieve both, not only to keep clear video conferencing, but also for data sharing.
3. Data exchange Traditional Shuangliu Council can only send one side while viewing the data can not be modified, it can not save each other to send data;
An interactive whiteboard applications, both sides can watch while the other side of the screen changes, you can save any of it on the project design unit is undoubtedly a very useful feature, Shanghai Baosteel, municipal design institutes, design institutes have adopted modern Hong combined with video conferencing, interactive whiteboard combination of video and data communication
4. Operational Very simple operation of the interactive whiteboard, you can use as word Like to use, and eliminates the transmission of data Shuangliu module a series of complex procedures
5. Extensibility Shuangliu module can only use video conferencing, and interactive whiteboard installation, you can use in video conferencing can also be used independently to conduct local meetings or teleconferencing, conference calls can also be combined with other systems using , scalability, more
6. Prices A simple interactive whiteboard module price is lower than the Shuangliu
This program has been the country as widely used interactive whiteboard has largely replaced the Shuangliu module, the current corporate headquarters offices in Ningbo, also being used with this program Morning.
