Add wings for HD video conferencing

People often associate the application with a fixed venue when speaking of HD video conferences. However, just in the Shanghai World Expo Park area of China Mobile TD-LTE integrated business demonstration car, reporters found such a no need to connect to the high-definition video conference room cable: 65 inch on the high-definition display, whether in China Mobile Expo communication command center, theme pavilion mobile HD conference room, or even take another TD-LTE test car staff, they all sat together with reporters for "face-to-face" and "eye-to-eye" communication. Sound and Image Height synchronization, coupled with the unique features of real-size HD display and "voice recognition", when interacting with conference participants in different locations, reporters are also jumping between different locations in an instant ......

This is an unprecedented new experience of mobile HD conferences. The advantages of LTE-based high bandwidth and mobility have completely removed the reliance on fixed conference rooms. It can be foreseen that the mobile high definition conference based on TD-LTE will surely start a new era of video conference, while HD and mobile are two key words.

HD has triggered a major leap in the history of traditional video conferences. However, pure HD is obviously not enough. What people need more is an immersive experience. This requires not only high-definition screen display, but also a combination of multiple technologies, such as 48: 9 high-definition video image acquisition, digital image stitching Without shadow, 3 × P extreme high-definition video, etc., so that traditional video conferencing has made great strides in the aspect of unity and authenticity.

Compared with traditional video conferencing, TD-LTE mobile HD video conferencing brings people an absolute dual impact from vision and hearing. If traditional video conferencing is "Alto", it solves the problem that people can "use" the remote presentation service; so TD-LTE mobile HD video conference is to upgrade it to "add a pair of wings of Audi", through the new smooth experience, it has achieved a major leap from "usable" to "well-used", making up for shortcomings such as the weak sense of presence and barriers to communication in video conferences. In the TD-LTE business demonstration car and another test car connection and through mobile HD video conferencing interaction process, reporters can be the other side of the window outside the scene clearly, it can capture the movements of the other Party raised their corners of the mouth, and instantly cast their eyes on other places, and even feel the location of the speaker. The detailed information acquisition will obviously provide more reference for conference exchanges.

Mobile is a major "Liberation" of traditional video conferences ". In the past, due to the existence or absence of a fixed network, video conferencing can only be performed in a dedicated video conference room located in a fixed location. In this way, although it is less difficult to travel, it is still limited by a specific location. Now, the emergence of mobile HD video conferencing based on TD-LTE wireless network not only get rid of the dependency on the cable, but also make the communication with the mobile characteristics: can communicate with people everywhere anytime, anywhere, no matter where you are, as long as you are in the TD-LTE network coverage can be; can also participate in the meeting in the mobile status, for example, in a high-speed car ).

HD video conferencing can be achieved only with mobile broadband networks with powerful performance, such as TD-LTE. As we all know, HD video is the most network bandwidth-consuming service, while interactive HD video conferencing is also used in both directions. According to China Mobile's demonstration staff, mobile HD video conferencing requires a bandwidth of 4 mbps for both upstream and downstream operations, and is the minimum limit that can be compressed after various advanced technologies are applied. Obviously, this is hard to achieve in the 3G era. At this time, the advantages of the TD-LTE will show the most vividly, the maximum downstream 100 Mbps, the maximum upstream 50 Mbps bandwidth, provides a strong support for HD video conferencing. In addition, the TD-LTE has a lower latency, making the feelings of both sides of the exchange almost the same as the real face-to-face. To give a simple example, the mouth changes on the screen of the other party are exactly the same as the words of the other party, which is clearly equivalent to the current fixed high-speed broadband network.

TD-LTE mobile HD video conferencing, in fact, is creating a brand new working mode. People can participate in meetings anytime, anywhere, and cooperate with video surveillance, live broadcasting, and other mobile video applications for on-site office work ...... It can be said that under the impetus of TD-LTE, the communication obstacle formed by spatial distance is gradually crossed, and the idea of "communication makes life better" is becoming a reality.
