How To Share A Video Conference System

How to share a video conference system

As the most efficient way of information exchange in the new era, the online videoconferencing system has been accepted by many people, and people have not reached the extreme in the application of the technological products of this new era. The screen sharing function in the remote video conference system is extremely useful for remote training and daily meetings, and it is also a frequent function for many functions. However, the screen sharing transmission efficiency has always been a need for video conferencing software systems to improve. The screen sharing needs to transmit data is generally relatively large, especially when the document page or the screen changes greatly, the data transmitted by it is quite large, so how to effectively reduce the screen shared data and maintain the quality of the screen image , becoming the most urgent problem in video conference development. In the development of screen sharing for video conferencing, there are three possible ways to implement:

1.Picture compression method

The picture compression method is to take a screenshot of the screen image, and then compress the picture. The compression format is usually a jpg or gif format. The compression ratio can generally reach 1:20 to 1:40, so this method is more direct than the screen image. To save bandwidth.

2.Improved picture compression

This method detects the screen image. If the screen image does not change, no data is transmitted. When the screen image changes, only the changed area is transmitted. How do we transfer the change only? We can divide the desktop picture into any number of squares. If the picture in the square changes, the entire square is transmitted, so that the purpose of bandwidth saving can be achieved through local transmission.

3.Through image compression

The other way is to directly compress and transmit the screen image by means of image compression coding (such as H.264 encoding). This method is basically the same as the second method, and is used to remove image frames and frames. Redundant, but the traffic through image compression is less than directly using image compression.

In summary, in the development of screen sharing for videoconferencing, we can use the above methods to detect images, and then use image compression for compressed transmission. In addition, we can also use direct image compression algorithms for transmission. The method, recommendation or use of the former, its effect is higher, the transmission bandwidth is lower, and it is more suitable for transmission on the public network. Videoconferencing can also support various OFFICE documents such as PowerPoint, Word, Excel and PDF, Visio, AutoCAD, txt documents, pictures and other forms of documents, and supports over 500 pages of large documents, efficient real-time screen sharing technology, support Web pages and other programs are shared, and desktop sharing is also supported.

With its strong R&D strength and deep technical accumulation, Tenveo has always led the industry's technological innovation and market transformation. The video conferencing system launched can be called the world's most cost-effective video conferencing product for global business: video conferencing, video conferencing Software, videoconferencing terminals, videoconferencing systems, videoconferencing service providers.
