Analysis of Future Video Conferencing and Screen Sharing Technology

Analysis of Future Video Conferencing and Screen Sharing Technology

Video conferencing has become a pan-era, video conferencing is not a large enterprise and government agencies have, small and medium enterprises and general education and training are open video conferencing mode. Video conference since the development of information technology mature and rapid development, relying on ordinary equipment, or even a smart phone can achieve video calls, and in the future, the development of video conferencing will have more space.
The future development of video conferencing features
In the video conference development situation under the good situation, the future, video conferencing development will show the following characteristics:
Trust comes from safety
As early as in China to build the first conference network, it has put forward the video conferencing system security issues. Since last year, individual manufacturers of video conferencing system security issues continue to exposure, but also to a variety of customers pay more attention to system security issues. Especially in the financial industry, video conferencing systems, the security issues more attention.
The future of video conferencing technology will be given from three aspects of user security protection: a secure system architecture, multiple data encryption technology, a sound management mechanism. Future video conferencing only through the authority of the staff can enter; not due to system vulnerabilities lead to information leakage; multi-server cluster technology to ensure that users will not be due to server problems caused by data loss. So that security issues do not become one of the factors that customers worry, get real protection.
Easy to get started is a good product
With the advent of the cloud era, video conferencing applications are no longer a simple information communication tools, but began to integrate into the government and large enterprises of the various functional departments. And too complicated operation will increase the user’s use of the burden, resulting in the use of inefficient and reduce the practical value.
Different from the government and large enterprises, small and medium enterprises are often limited professional knowledge, complex operation directly affect the user’s enthusiasm, is not conducive to the use of habits to develop. In the low-end market, in addition to cost, the system’s ease of use also makes people pay more attention to the complex system of simple management to become the development trend of all IT applications.
Whether it is large enterprises, small and medium enterprises or individual users, although their demand for video conferencing systems vary, but the demand for ease of use is the same. In order to meet this demand, video communications professionals will pay more attention to the interface of the beautiful and easy to operate. Professional analysts also pointed out that ease of use to promote the popularity of video communications products in the enterprise market is essential.
Mobile is the mainstream of today
Today, the application boundaries of video communications products are being expanded, and porting video communications products to mobile device devices will become a trend. At present, such as Microsoft Lync platform, IBMSametime, Alcatel-Lucent MyTeamwork and other UC platform exists, to promote video communications products and UC platform to accelerate seamless compatibility, and its integration with the unified communications will be the future direction of development.
At the same time, mobile video conferencing also improves the efficiency of information exchange, work efficiency will be greatly improved. Although it is not the mainstream form of video conferencing, but its outstanding advantages of convenience, greatly meet the diverse needs of users.
With the issuance of 3G licenses, China’s telecommunications industry has officially entered the 3G era. Although the current mobile video conferencing is still in its infancy, but the road is twists and turns, the future is bright, I believe that in such a favorable premise, the future, mobile video conferencing will become the mainstream mode of communication.
Diversification of future trends
For a long time, government procurement and financial, energy, telecommunications and other industry users has been the main driving force of China’s video conferencing market. These users of the video conferencing system procurement with a one-time purchase of large amounts of product safety and stability requirements, the general use of self-built network system and other characteristics. Moreover, these industries for video conferencing solutions are also different requirements, how to meet the different needs of each customer? Only the market segment is the future development of the way out.


How to achieve video conferencing screen sharing
Video conferencing screen sharing function in many functions inside the use of more frequent functions, whether it is remote training and daily meetings, screen sharing are often required to use. But the screen to share the transmission efficiency has been the video conferencing software system needs to be improved, the screen needs to transfer the data is generally larger, especially when the document or the screen changes a large change, the transmission of the data is quite large, so How to effectively reduce the screen to share the data and maintain the quality of the screen image, video conferencing development to become the most urgent need to solve the problem. There are three ways to implement video sharing in a video conferencing:
1, picture compression method
Picture compression is the screen image screenshot, and then the picture compression, compression format is usually jpg or gif format, the compression ratio can generally reach 1: 20 ~ 1: 40, so the way than the direct transmission of the screen image In order to save bandwidth, but the way to achieve the screen to achieve the required bandwidth is still very large, because we need to intercept images every moment, and then compress the image, the final transmission of images, transmission image redundancy is very Large, as we screen the same time, this way or the transmission of data, can not effectively save bandwidth.
2, improved picture compression
This method of the screen image was detected, such as the screen image does not change the time, not the data transmission, when the screen image changes, only to change the place to change, that specific how we only change the place? We can divide the desktop image into a grid, if the box within the picture changes, put the entire box to transfer, so that through the local transmission to achieve the purpose of saving bandwidth. The drawback of this approach is that the size of the grid determines the efficiency of the screen transmission, the more the more data transmission grid structure, but the image redundancy is lower.
3, through the image compression mode
Another way is to directly through the image compression coding (such as H.264 encoding) on the screen image compression and transmission, this approach and the second way the principle is roughly the same, are removed between the image frame and frame Redundancy, but the flow through the image compression method than the image compression method will be less, the main reason is that we use the image compression algorithm is through the picture within the frame, the compression outside the frame, the efficiency of the picture than the direct compression The difference between the part of the higher.
4, through the Hook detection method
In front of several ways are related to the need to detect whether the desktop image and the previous image is different, but the detection method is not optimal, such as the image compression method of the lattice is relatively small, the transmission of data structures will be more, And improved picture compression, the lattice is relatively large, transmission redundancy is also more. Hook mode is through the bottom of the drive to obtain the desktop image, and can distinguish the image before and after the difference, so that the transmission of smaller data.
In summary, in the video conferencing of the screen sharing development, we can use Hook way to detect the image to determine the scope of the desktop image changes, and then use the image compression for compression transmission, and we can also use the image compression algorithm directly Transmission, but the two ways, recommended or use the former, the effect is higher, lower transmission bandwidth, more suitable for public network transmission.

Key Technology Analysis of Common Video Conference System

Key Technology Analysis of Common Video Conference System

A complete set of video conferencing systems is usually composed of videoconferencing terminals, multipoint control unit MCUs, network management software, transport networks and related accessories.
First, the classification of video conferencing terminals
Video conference terminal is used to encode and package video and audio data, and then sent to the remote through the network, while receiving the remote transmission of data, unpacking, decoding, video, sound signal and output to the peripheral device The In short, the video conferencing terminal is a front end device that communicates with the far end during the conference. There are three main video conferencing terminals: desktop, set-top box, conference room type.
1. Desktop terminal
Desktop terminals are a powerful combination of powerful desktop or laptop computers with high quality camcorders (built-in or external), ISDN cards or network cards and video conferencing software. It can effectively make people at the desk or people who are traveling to join your meeting, and you face to face communication. Main applications: desktop video conferencing terminals are usually assigned to the office of a special person or a person traveling on a business trip. While desktop video conferencing terminals support multipoint conferencing (for example, meetings contain more than two conferencing sites), it is mostly used for point-to-point meetings (such as one-person meetings with another person).
Today, tablet PCs, smart phones and other mobile terminals can be mobile video conferencing terminals by installing specialized applications.


2. Set-top box type terminal
Set-top box type terminal is known for simplicity. In a unit contains all the hardware and software, placed on the TV. Easy installation, light equipment. A video conference requires only one regular TV and an ISDN BRI or LAN connection. The video conferencing terminal can also load some peripheral devices such as document projectors and whiteboard devices to enhance functionality. Main applications: Set-top box-type terminals are usually shared between the various departments of resources, from multinational companies to small businesses and other institutions of all sizes. It is often the company to buy the first “conference room type terminal”.
3. Conference room type terminal
Conference room terminals offer almost any solution required for video conferencing, generally integrated in a conference room. Conference room terminals typically combine a large number of attachments, such as audio systems, additional cameras, document projectors, and PC collaboration files. Dual screen display, rich communication interface, graphic flow selection makes the terminal to become high-end, comprehensive products. Main applications: conference room type terminal mainly for large and large enterprises and design.
MCU is the short term of the video conferencing system center control equipment, its full name is Multipoint Control Unit – multi-point control unit, also known as multi-point conference controller, multi-point video conferencing system is the key equipment.
MCU in the video conference is equivalent to a “switch” role, it will be from the venue of the information flow, after the separation, the extraction of audio, video, data and other information and signaling, and then the meeting site Information and signaling, into the same processing module to complete the appropriate audio mixing or switching, video mixing or switching, data broadcasting and routing, timing and conference control process, and finally the meeting site needs a variety of information Reassemble, sent to the corresponding terminal system equipment.
MCU mainly deal with three types of data:
1. The video signal is mainly done by the video processor
2. The audio signal is mainly composed of the audio processor
3. Data signal: mainly by the data processor to complete
In addition, MCU interface in the network interface module and control processor is also essential. The control processor is primarily responsible for determining the correct routing, mixing or switching of audio, video, data signals, and control of the meeting.

CCM- What are the main technical characteristics and advantages of telepresence?

J-P.B - Of the advantages, there is of course the exploitation of the non-verbal message, which constitutes 60% of the communication. A reaction on a face is sometimes just as significant as an absence of reaction. And to achieve this result, high-end equipment is used: plasma screens that reproduce a high-definition image at 1/1 scale (real size), a corresponding HD quality sound, Furniture. It's tailor-made.google hangouts alternative

Is the rendering realistic?

J-P.B - Yes. The set gives the impression that the remote collaborators are all in the same room. And this impression will soon be a reality - or almost - with the coming of 3D.

What distinguishes telepresence from other videoconferencing devices?alternatives to google

J-P.B - It must be clear, there is a clear hierarchy between these modes of communication: telepresence is a device of high quality that is suitable only for very large companies. In terms of IP communication, we are not in the same category. At least in terms of computing resources and bandwidth. The webcam requires 100 kb of throughput, intermediate devices about 500 kB ... But with telepresence we table at least on 3 MB of throughput. And the infrastructure must follow: it requires a meeting room and modern computer equipment.join me alternative

So it is a device that is only suitable for very large companies?

J-P.B - Yes. The installation of telepresence is a significant investment: we start from 100,000 euros. The tool is therefore primarily intended for the management committees of large companies whose managers and decision-makers are frequently in remote working situations.
