The anchor is a new career that has exploded recently

, The number of people engaged in the anchor industry and related industries in China has reached  

160  More than ten thousand people

.

In the whole industrial chain , The role of technical services should not be underestimated .

With the accumulation of a large number of use cases, rongyun and other communication cloud service providers , It not only summarizes the targeted live broadcast scenario solutions , It also completely encapsulates the business logic , Provide

Out of the box scenario  SDK

.

The product has built-in multiple confluence layouts 、 Lian Mai  PK  Equal ability , Make the linkage between anchors more convenient , Use technology to meet the needs of users of current live broadcast applications 、 Promotion and other operational requirements , Greatly improve the productivity of the industry .

In the current situation of fierce competition in the domestic industry and the growth of users touching the ceiling ,

Going to sea has become the key direction of various social pan entertainment Internet companies

.

Rongyun summarizes and sorts out best practices at home and abroad , One stop solution , And targeted to solve many problems when the live broadcasting business goes to sea .

The network is complex   Various equipment

Live broadcast applications have been developed for many years , From the perspective of the anchor's interactive playing method

Single anchor live broadcast 、 A single room with a live broadcast 、  Live broadcast across rooms

; From the perspective of media types, there are

Live audio 、 Live video

, also

Combination of audio and video

All kinds of interactive playing methods .

（ Live broadcast applications are mainly classified ）

As more and more live broadcasting companies choose to enter the overseas market , It is difficult to create image level applications by fully learning from domestic product forms and operation modes . Beliefs of users in different countries and regions 、 Customs and living habits , Adjust measures to local conditions , Explore new “ localization ” How to play , To find new growth points .

Business going out to sea will undoubtedly pose more challenges to the overall technical capability of live broadcasting , The first thing to do is

The complexity of networks and terminals

problem , After all, this directly affects the audio fidelity of the live broadcast 、 Quality and clarity 、 Fluency and other core experience indicators .

Global network diversification ,

When it comes to network type differences 、 Infrastructure differences 、 Special line construction restrictions, etc . Overseas countries at different stages of development , What the user uses

Terminal conditions are very diverse

, such as , Middle and low-end equipment has very high requirements for product performance , as well as  iOS   and  Android  The system is in the process of rapid iteration , Facing problems such as multi version compatibility .

Rongyun has several independent data centers overseas , Have coverage

The global  233  Countries and regions

Thousands of access nodes , Provide stable overseas links 、 Optimal communication quality 、 Secure data backup and reliable business disaster tolerance . Links for global layout , Rongyun has built a monitoring system . Through this platform , You can query

User access point 、 Access equipment

as well as

Used rongyun  SDK  edition

Quality of service , You can also get the relevant information of the user's subscription flow in the business process , And through various monitoring points , To monitor the overall audio and video service status , It is convenient to quickly locate the fundamental problem 、 Accurately formulate the optimization scheme .

Specific to the live broadcast scene , Cloud melting is based on years of precipitation  IM + RTC  Low level communication capability , Provide low latency for developers going to sea 、 More flexible audio and video services .

Low latency ：

Melt the clouds to “IM+RTC+X” All communication solution is the framework , In terms of audio and video, distributed communication network is adopted , take  RTC  Low latency live and traditional  CDN  Live broadcasts are included .

（ Rongyun low delay live broadcast framework ）

More flexible ：

Through flexible interfaces , Developers can easily implement the publishing and subscription logic of audio and video streams in different scenarios .

The rongyun live broadcast solution is designed , Fully consider the correlation between audio and video streams and personnel online status , allow

When the network is poor, the user drops the line and immediately resumes the line ;

After the user is offline , Instantly clear the connection status ,

avoid “ Ghost wheat ” Etc

.

user “ Enthusiasm ”  room “ crowded ”

Compared with domestic , Live broadcast users in many foreign regions are more or less expressive . Although because of differences in culture and customs , Different regions have a certain category preference in entertainment and social networking , For example, users in the Middle East prefer chat rooms , Live games are more popular among enthusiastic Latin American users . But overall, it shows

More people , room “ crowded ”

Characteristics .

Take Yu chat room as an example , It is generally used in China  1+8  Wheat bit mode of , Overseas entertainment live broadcast scenes are more lively , The number of wheat users tends to increase .

（ more “ lively ” Overseas application of ）

First , The technical scheme involves

Window layout of the live broadcasting room

and

Audience subscription stream

The problem of .

Because each anchor is in a different region , Different network conditions , And the network bandwidth of the audience is insufficient , It is easy for viewers to get stuck when they subscribe to each anchor stream .

Rongyun recommends

Audience side pull confluence

, The audience only needs to pull a stream to see all the anchors . Rongyun media service cluster has a powerful layout convergence service system , It not only supports the fusion of the original video pictures in any layout , It also supports adding text or pictures to videos , To meet the needs of live viewers for timely access to anchor information . If the application developer still wants to  CDN  Add beautiful icons such as rank medals on the audience side page , It can also be combined with reading and writing  SEI  function , Transfer more information in the video stream , Ensure that the annotations and video content seen by the audience are synchronized in real time .

Rongyun also provides

Live broadcast scenario  SDK

 , Built in

 7  Common live broadcast layout templates

, It is convenient for developers to pass a few  API  Just set up the scene .

（ Cloud live broadcast scenario solution ）

secondly , Multi person live broadcast right

High quality audio and video experience

It's a big challenge .

Integrating cloud and tradition  3A  Algorithm and  AI  Algorithm , Create high-quality audio processing capability , It can satisfy many people to speak on the microphone at the same time 、 Sing a song .

The audience only needs to pull all the way together to clearly hear the happy dialogue between the anchors . When the multi anchor is connected to the microphone , An anchor can unsubscribe from the audio of other anchors , At the same time, it can prevent the sound from being transmitted to the audience .

Only those with these abilities , That's why we are now online  Party  Make it possible .

（ Multi person live broadcast audience convergence pull ）

Last ,

The chat room in the live broadcast room also needs to effectively manage massive messages

, quite a lot  App  To avoid a message explosion , Adopt the strategy of restricting users from sending messages in a short time and at a high frequency on the mobile terminal .

（ part  App  Restrict users from sending messages at high frequencies ）

Melting clouds  IM  The massive concurrency architecture of chat rooms has been tested for a long time

, Support chat room massive message concurrency . meanwhile , Rongyun relies on years of experience in live entertainment scenes , Precipitated a complete set of message speed control schemes .

The core of message speed control is , This requires prioritization of messages ：

White list messages

, The highest level of importance , Generally, system notifications or management information will be set as white list messages ;

High priority

, Second only to white list messages , Messages without special settings are of high priority ;

Low priority

, The lowest priority message , Most of these messages are text messages .

How to divide , Developers can set it in the background or through the interface . The server implements different speed limit strategies for three messages , In high concurrency , Low priority messages are most likely to be discarded . The server stores three kinds of messages in three message buckets , When the client pulls a message, it sends the message according to the white list  ＞  High priority messages  ＞  Sequential pull of low priority messages .

in addition , Live broadcast going to sea should not only do a good job in localization and interaction , It should also be established in combination with local policies

Content risk control system

. Sensitivity to the local culture of the business and knowledge reserve , It is a necessary condition for risk control .

Rongyun cooperates with leading professional partners in the industry , Help developers in social scenarios , Accurately identify instant messaging 、 Text in real-time audio and video services 、 picture 、 Audio 、 Video yellow 、 Violent 、 Fear and other illegal contents , Meet the requirements for safe operation of live broadcast scenarios .
