Have you ever encountered such a dilemma?
Away from home coincidence emergency meeting, phone access vague, scratching their heads like ......
Enterprise remote branch, a meeting co-slow, shrugging like ......
The high cost of off-site meetings, sighing like ......
Cross-regional cross-enterprise communication, inefficient, helpless like ......
These how to do?
A meeting about it, as a business-class talent, it definitely is an important thing but it makes a lot of trouble, when to let us do things correct phone in hand on business meeting, multiport Imagination can experience high-definition effect, and flexible expansion cost is not high?
So that we dare not to worry about all kinds of remote branch pit cooperation meeting, which can enjoy more "zero distance" conference, sharing collaboration breezy, this wave operation sounds feel flattered.
The face of these many challenges and vision, as a result of this work on mentally exhausted "enterprise-class talent," knows in today's era of rapid development of information technology, efficient communication and cross-enterprise, cross-regional team work is the key to how every day important, but as an important tool for information and communication links of enterprise communications technology, with the full maturity in cloud computing, artificial intelligence and promote 5G technology, it can help companies to complete real-time information and decision-making links cloud communications to help businesses save manpower, material and time costs from the root of the cloud video conferencing products have emerged.
Turning to cloud communication, in fact, has long been obvious to the enterprise communications market trends in the transformation of the cloud, not only brought about changes in communication, contributed to the fusion of Internet and cloud services with the butt of resources but also to some extent, it will be referred to business information center was also not an exaggeration. According to IDC released "2018 China in collaboration with the video conferencing market tracking report," IDC industry data and research institutes, to cloud the domestic video conference software conference as the representative of the market size of about 13.3 billion yuan, the growth rate in the next five-year CAGR 25%. Seen in this light, cloud video conferencing has become a trend.
Development prospects are so great, but the growth is related to the field of domestic cloud video conferencing, compared with foreign developed markets still slow some, the problem may focus on system compatibility, security risks are even more aspects of "cloud slow" and so on. Nevertheless, relying on a strong technology Tencent Tencent cloud multimedia laboratory provided by the innovation enterprise cloud breaking meeting, ballast stone cloud video conferencing "Tencent meeting" is still in a powerful and positive experience, marked by a video conference market shot in the arm. So, exactly how it is done is easy to use, safe, reliable, low barriers to entry but work together and "cheapening child" it? In this regard, Adan honor to interview a number of technical experts Tencent multimedia lab, as we present details about the meeting behind Tencent exactly what some technical support, together with Tencent unveiled a multimedia laboratory.
Secret! What cool black technology behind how "Tencent meeting"?
Based on 20 years of business Tencent audio and video technology accumulation, the release of "Tencent meeting" to ensure that different devices, systems, and distributed in the bottom of the participants around the world brought about by the global low latency network, naturally easy to open a smooth high-definition audio and video conferencing. In other words, Tencent multimedia laboratory by fusing classical signal processing, hearing and psychological depth learning theory, the complex nature of the end for audio communication links, helping to create high-quality, low latency, strong resistance to new generation of intelligent real-time audio video solutions to enhance the user's audio and video experience.
Multiport collaborative, high-definition experience, flexible expansion was not enough, Tencent meeting while both meetings to share documents, bokeh, portrait, beauty and tracking, AI voice noise reduction, security escort and other intimate super multi functions and services. Next, let us together Secret "Tencent meeting" behind the black & bar.
Currently, audio and video conferencing products on the market and a few, this multimedia laboratory Tencent technical experts stressed that, despite numerous audio and video products, but from the technical details of the user experience all there is a big difference, whether it is from the network, quality assessment or audio and video processing, the Tencent conference this product reflects the competitive advantage of a business trip alienation. For example, in terms of interoperability, Tencent Media Lab opened the traditional PSTN and VoIP phones and other access devices that support multiple sample rates and bandwidth from narrowband, broadband to ultra-broadband.
The reason so users can receive high-definition voice quality video calls, in addition to ultra-grading black blessing audio technology, taking into account the complexity of the system of voice calls, Tencent multimedia lab also created a real network scenarios for the transport of voice quality peacekeeping and security programs, the quality of real-time detection of the call, and the noise of the noise quickly positioned to continue to guarantee high-quality calls. In addition, to ensure that participants can have a quiet remote communication environment, Tencent multimedia laboratory designated specifically for noise reduction, such as noise common keyboard sound, cough sound, turn on the water cup sound, etc., to ensure that participants in the intelligent noise reduction worry-free environment to concentrate on meeting the other.
How do the remote collaborative meetings with people in the same room face to face experience no difference? Experts say this technology, according to international standards IPO, end to end delay of 150 milliseconds need to control in order to ensure good audio communication experience effect. For end delay problems in the existing environment, a communication network environment as part of the context of the most complicated, its state is not controllable. "In order to achieve good communication effects, we achieve as much as possible in limited circumstances the optimal value, such as non-destructive in the extreme, no packet loss, latency under low, even up to 67 milliseconds delay limit. In this optimization Based on the network for the state to do real-time detection, real-time feedback results obtained in further policy adjustment; if the network suffered a similar loss or delay and other unforeseen circumstances, we will adjust the transmission strategy against fluctuations in network ultimately, despite the delay there will be some fluctuation in the direct network, but does not affect the subjective experience of the participants. "technical experts detailed answers to this question. In addition, based on packet loss compensation technology Tencent excellent multimedia laboratories, can achieve 70% packet loss and audio loss in 80% of the video, we can still ensure a smooth meeting.
How to ensure that users of Tencent meeting data privacy and security? Especially for users of financial data loss and leakage are any irreparable damage. For security issues, which properly properly to Tencent seven security laboratory for the user "escort aircraft" it.
