WebRTC, the name derived from the web page instant messaging (English: WebReal-Time Communication) is an API that supports web browsers for real-time voice dialogs and video conversations. From simulation to numbers, from MPEG to H.265, from SIP / H.323 to WebRTC, the Evolution of real-time Internet technology standards affects each company's strategic and technological selection in the industry, AnyRTC-based web-based web-based audio and video Real-time communication cloud platform, this invitation of AnyRTC Market Product Center Director Wei Guangxian, introduces us a new breakthrough in the development of video real-time interaction.
Q: A & S Security Knowledge Network
A: AnyRTC Market Product Center Director Wei Guangxian
Q Please briefly introduce the area that is mainly engaged in AnyRTC?
A: AnyRTC is a PaaS cloud service provider providing audio and video real-time communication, an abbreviation of AnyReal-Time Communication, is intended to provide users with the experience of "always anywhere in real-time communication", which is independently developed by Platinum Information Technology Co., Ltd. Real-time communication PaaS cloud platform, AnyRTC provides customized SDK / APIs in various industries, such as security industries, education industries, financial industries, entertainment, etc. have a large number of SDK / APIs.
What are the security industries SDK / API created by QAnyRTC? What kind of scene is suitable?
A: AnyRTC Security Industry SDK / API mainly has a visual intelligent scheduling SDK, prison remote perspective SDK, remote access control SDK and so on require real-time audio and video communication schedule. Among them, the visual intelligence scheduling SDK has the following functional modules: cluster intercom, video scheduling, video conferencing, monitoring, supporting various external equipment access. It is mainly suitable for scenes that require emphasizing audio and video interactions in fire emergency command systems, railway / road scheduling systems, police law enforcement systems, logistics scheduling systems, blind / amblyopia, and other.
Q At present, the industry's program applies more extensive, and the security industry is the most relevant to custom-made visual emergency command dispatching system. What is the difference in compared with traditional command dispatch platform?
A: The traditional command dispatch platform provides a complete set of soft hardware solutions, and AnyRTC is only the software audio and video real-time communication schedule related modules, is a PaaS platform. AnyRTC is mainly to b, all products that require real-time audio and video communications, can choose to embed anyRTC communication module, during the entire application fusion process, AnyRTC is responsible for providing audio and video related packaging services, and helps relevant hardware adaptation optimization And industry customers have developed their own business, and audio and video communication modules can be implemented with only a few simple APIs.
Q How to see the audio and video real-time interaction in the security industry?
A: If it is just a simple video surveillance, unilateral draw flow is enough, but with the continuous upgrade of the mobile network, the mobile phone-based application scenario demand is implemented. A few examples:
Law enforcement recorder, from the earliest number of simple local video accumulation, upgrade to the current rear real-time monitoring of front-end law enforcement records, and in real time, in real time, multi-party synchronous collaborative handling case;
Railway inspection (this is similar to road inspection, environmental inspection, etc.), from all over the human patrol, manual record report, upgrade to now 4G single soldier terminal or operation drone, backend staff Real-time viewing, encounter faults or danger, can be processed in time, and coordinate all the front-end personnel through single soldier terminal;
When the disaster, the front-end disaster relief personnel wear a single soldier terminal, and the commander can see the front-end disaster in real time. Comprehensive multiple front-end conditions make commands, while the front-end disaster relief personnel can also see each other through the single soldier To each other and real-time communication, make effective disaster relief in time, after all, under the disaster, time is more expensive than money;
Blind navigation, backend community Zhigong can combine GPS real-time positioning according to the camera (smart glasses, mobile phone, watch, etc.) carried at any time, giving blind guidance.
There are still many application scenarios involving real-time interaction, and here is simple to introduce 4 common types.
Q For engineers or integrators, do you understand your technology?
A: Traditional SDK docking, usually need to start from the bottom of the protocol, such as SIP, H.323 docking, etc., which requires very professional engineers and teams to be implemented. AnyRTC is based on WebRTC development, all docking is packaged into an API form, no need to contact the underlying protocol, directly call the API, only need to apply the engineers developed, you can complete the docking work. Also, AnyRTC can customize the industry's SDK / API for customers. Of course, AnyRTC is not anemn, and can only pack all the service that is on audio and video interaction, and some end customers' other non-audible video related requirements. Need yourself to complete the product business / engineering / integrator.
Q How to ensure the security of audio and video communications?
A: AnyRTC's SDK / API takes a three-level encryption mechanism:
System Transfer Protocol HTTPS / WSS: Transfer by HTTP and WS protocols, the protocol itself is clearly transmissive, so for data security, we use SSL as an encrypted channel to deliver data over SSL;
Signaling DTLS encryption: Since it is not very safe, it is not very safe, so it is not very safe, so the signaling is subjected to secondary encryption, and the AES-256 symmetric encryption algorithm is encrypted;
Streaming media SRTP encryption: After encryption, it can effectively prevent the eavesdropper from obtaining content in the communication stream, even if the media stream is intercepted, only the session participant with the encryption key can decode the media stream;
Q as an expert in the audio and video real-time interaction technology and intelligent algorithm, what is the biggest advantage of your company?
A: As mentioned earlier, AnyRTC is developed based on WebRTC, in addition to inheriting WebRTC's allments, such as:
The interaction of audio and video can be directly implemented without any plug-in without any plugins;
Time: Inner Net 50ms, Internet 200ms;
Dynamic adaptive: dynamically adjust the code stream according to the network bandwidth;
A variety of encoding protocols: support H.264, H.265, VP8, VP9, AV1 and other coding protocols;
All platform support: support Linux, Windows, Android, IOS, Web, Mac, H5, Unity3D and other platform development.
In addition, ANYRTC has several major features for the industry:
Support private cloud deployment: In addition to supporting the use of self-operated PAAS cloud platforms, it also supports private cloud deployment, which combines security industries with high security requirements, and other Internet peers are not supported by privatization.
Personalization customization; ANYRTC can be customized to the logical layer of SDK and application layer for industry, in addition to the specific industry needs of the customer, in addition to the specific industry needs of the customer, and provide customized development for quality projects.
Ultra-low server performance requirements; AnyRTC uses video conferencing of the server that is not optimized to the server, the ANYRTC's server is used by the SFU mode, 100 channels 720p video and it requires 1 core 1G. The server can be implemented.
Q Which successful cases currently can share it?
A: The visualization schedule for the security industry is integrated with private cloud mode. At present, there is already relevant cases in railways, highways, law enforcement dispathes, prison remote visits, but we have added with our customers. The confidentiality agreement cannot be disclosed within the specified annual limit, and can only be introduced in the form of base DEMO.
Q Do you think that these technologies are in commercial applications, what is the biggest difficulty?
A: Many manufacturers in the security industry have an understanding of audio and video interaction SDK modules, but also on traditional SIP, H.323, WebRTC as an emerging technology, regardless of integrated difficulty, or on mobile application performance It is not a comparative technology. And the WebRTC has no plug-in, browser native support, all platform support, etc., becoming an irreplaceable advantage of audio and video interaction in the Internet platform. So, I also take this opportunity to recommend this emerging technology to the industry, so that everyone has more better choices on the application of audio and video interactions. , Read the full text, description: A & S conversation AnyRTC: WebRTC promotes cross-platform command dispatch, triggers security application new ideas
