In 2020, the online live broadcast industry will still maintain a steady upward trend of development, and the forms of live broadcast will become increasingly diversified. “Nationwide live broadcast” has become the mainstream of the era. However, at the same time of development, some disadvantages are gradually exposed. In the situation of continuous expansion of user scale, the technical ability of live broadcasting has become a stumbling block to the development of the whole live broadcasting industry. In order to promote the rapid development of the industry, the live broadcasting industry urgently needs a set of more perfect end-to-end live broadcasting solutions.
Global live streaming services

End-to-end live scene solution

Monthly live users of a large live broadcasting platform in China have exceeded 100 million. With the increase of users, live broadcasting sessions and anchors, problems such as delay, lag, clarity, high concurrency, illegal live broadcasting management and content review are constantly exposed. Faced with the problem of business growth by technical bottleneck restriction, seven NiuYun provided from the live stream, video processing, content distribution to broadcast the integration of technology solutions, and provide real-time transcoding, live recording playback, delay live, live jian huang, cover, dynamic watermark, live broadcast time shift, even m intercom and abundant data processing services such as data monitoring.
Pili is an end-to-end live broadcasting solution based on the powerful global real-time streaming network, perfect client service and cloud service, which perfectly solves the technical problems such as delay, lag, high concurrency and management of live broadcasting violations in live broadcasting scenes. Next, we take social live broadcast as an example to analyze how video live broadcast solutions overcome technical problems in live broadcast and the live broadcast management functions provided by the console to customers.

7 niuyun real-time network LiveNet, overcome delay, lag, high concurrency **

In order to fundamentally solve problems such as delay, lag and high concurrency during users’ live broadcasting, Qiuniuyun provides users with a real-time streaming network LiveNet that is globally integrated, intelligent scheduling and streaming data transmission. The first technical feature of LiveNet is the fundamental change in the way of networking. Instead of a region-oriented multi-center tree-like hierarchical network, it has become a decentralized self-organizing global integrated mesh network.

Seven niuyun LiveNet- self-organizing network _
This network structure has obvious advantages over the early tree-hierarchical network:
** Scale on demand: * * mesh network model based on LiveNet, any one connected to the server, can have a key after effective authorized remote flash, a key deployment, a key operation, a contribution of self-organizing network resources of this kind of lightweight flash, the expansion of the node is extremely efficient, really can do infinite node is outspread, Quickly respond to the needs of coverage anywhere in the world.
Smart line selection: * * * * fixed finite line, compared with the tree network LiveNet mesh network internal line is dynamic and flexible combination, and each adding a node, on line combination, based on the platform of dividends, could lead to an order of magnitude of combination may, based on the dynamic combination of line and real time data, can be decision scheduling optimal routes.
** Fault tolerance: **LiveNet has moved away from the traditional static network topology and adopted a software-defined network approach, replacing manual static configuration with procedural intelligence. The benefits are not only the dynamic combination of lines, but also the normal handling of node failures.
Another feature of LiveNet is intelligent scheduling. The lines in LiveNet’s mesh network are dynamically and flexibly combined freely, not limited to a limited set, and the more nodes there are, the more lines will be combined. The mechanism of dynamic combination nodes flexibly drawing lines makes it possible for programs to find high quality lines.
** Powerful console and API, ****** for users to manage live business in real time ****

Seven Niuyun Live video management console
Qiuniuyun also provides users with a complete management console and API. Users have their own console, and users who log in to the console can manage relevant live broadcast data. These include:
** Live broadcast space Settings: ** Live broadcast space can be regarded as an abstract collection of users’ entire live broadcast business. In a live broadcast space, users can flexibly configure the domain name of push stream/play, and this group of push stream/play domain name shares all live streams in the live broadcast space. You can configure unified functions such as authentication, recording, transcoding, watermarking, screenshot, yellow authentication, retweet, on-off event callback, and low-delay HLS for the live broadcast space to closely cooperate with customer services.
** Live streaming management: ** Users can obtain the online status of anchors, streaming IP, streaming duration, real-time number of players and other information through the console page or open API. You can also perform operations such as screenshot, transcoding, yellow authentication, and time segment recording of live streams based on your own service requirements. For the live broadcast of specific scenes, AI yellow authentication and other functions can be enabled to timely supervise the live stream and block the live stream if necessary.
Statistics: * * * * in the data statistics, seven NiuYun provides detailed business class data usage and operation analysis, such as TDD customer has bandwidth, various specifications of transcoding length, number of yellow area and heat statistical operators level of play, convenient user different decision makers in the company according to their own needs to obtain useful data.
For example, according to the transcoding cost given in the data analysis, the service team calculates whether transcoding is needed and how much bandwidth will be increased if transcoding is not done, so as to adjust the cost strategy. According to relevant operation data, the operation team can analyze where audiences are concentrated on the live broadcast platform and what contents they are interested in, so as to obtain more audiences. All these problems can be solved on the live broadcast control platform.
At the same time, Qiuniuyun provides expandable open API from live broadcast space to live stream to facilitate the development of fast access and management of live broadcast services; The development package of push stream, play and server SDK with rich scenarios is provided to help enterprises quickly build live broadcast business system based on various SDK, without paying attention to technical details and reducing development costs.
** Stable and reliable live playback solutions, ****** support automatic recording data permanent storage ****

It is also crucial for live broadcast platforms to have a stable and reliable solution for live broadcast playback, so that some hot content can be saved and reused. This needs to meet customers’ basic needs for real-time recording and storage of live streaming. Qiuniuyun provides users with real-time recording and on-demand playback functions, and supports automatic recording to permanently store hotspot data in current live streaming or history of live streaming.

Pili is a global live streaming service and end-to-end live streaming solution specially designed for live scenes in the era of the explosion of live video. Perfect solution to the three major problems of high technical threshold, high cost and lag delay rate in the live broadcast scene, provide strong technical support for enterprises in the flood of “national live broadcast”.
