China’s webcast industry started in 2005 and entered the outbreak period in 2015-2016. During this period, under the dual pressure of policies and capital, the live broadcasting industry ushered in a reshuffle. During this period, the battlefield of live broadcasting shifted from PC terminal to mobile terminal. At the same time, all industries began to favor the form of live broadcasting, and the live broadcasting industry also penetrated from a single show field to e-commerce, education and other fields. In 2020, due to the impact of the epidemic, the resumption of work and production was delayed, and some industries mainly operated offline tried live streaming on the waterline. The number of livestreaming users was diversified, and the scale of livestreaming users was further expanded. By March 2020, the number of livestreaming users in China reached a new high of 560 million, in other words, more than 60% of Chinese Netizens were livestreaming users.
Sometimes, live broadcasting is one-way, such as e-commerce live shopping, anchor mouth broadcast, buyers watch, order, bullet screen, brush gifts can be. But nowadays, more scenes of live broadcasting are two-way interaction, and Lianymai interactive live broadcasting has become the standard of the live broadcasting industry. Real-time meeting, online small class, multi-person real-time chorus, chat room, online karaoke room and other scenarios, all need to constitute two-way real-time interaction with continuous mic. The important factors affecting the effect of continuous mic include delay, sound quality, stability, etc. Otherwise, there will be many problems such as high delay, lag, content asynchronisms, high noise and so on.
There are generally two scenarios for live broadcast: one is ordinary live broadcast with one anchor and many viewers, most of which use the RTMP protocol and distribute through CDN, so as to realize large-scale and highly concurrent data distribution; The other is Lianmai live broadcast. The difference between lianmai live broadcast and ordinary live broadcast is that while ordinary live broadcast is similar to stand-up comedy, lianmai live broadcast is like stand-up comedy and group stand-up comedy. There are two or more anchors, among which we usually divide them into big anchors and small anchors. This is usually seen in the form of mobile live streaming.
What is Lianmai Live Interactive?
When the audience into the live chat room, often see news barrage, thumb up, a gift, this is a traditional form of interaction, in the interactive live even the wheat, the audience can be initiated with the host real-time aam, or between anchor and anchor the wheat – those in the age of television or the desktop look very common, but limited to the early mobile network and mobile phone equipment performance is not enough, Has been slow to show good performance on mobile phones. At present, no matter the situation of mobile network and its technology, there has been an obvious breakthrough, which makes it possible to live broadcast with real national interaction.
The realization of lianmai interactive live broadcasting can bring great experience improvement to more industry scenes. For example, in online education, oral teachers can allow students to participate in reading and making sounds in the process of teaching. Students can hear their own pronunciation and at the same time, teachers can timely correct their pronunciation, which can achieve good teaching results, which is a significant progress for online education.
For another example, more and more enterprises need video conferencing, and at the same time, they need to push conference information to more employees. Previous meeting of the group of large enterprises, the headquarters leadership meeting in a room, a long-distance branch staff also focused on the local studio, to watch the video to listen to the report form to participate in the meeting, and using a mobile phone conference broadcast live, first of all can solve all concentrated in the fixed place, don’t need through the video even wheat form between participants meeting to discuss, The whole process is combined into a picture and pushed to each employee’s mobile phone. This is a typical enterprise application scenario of interactive live broadcasting. While reducing the cost of meetings and improving the efficiency of meetings, it is easier for a meeting to achieve a good uploading effect.
The key to live interactive mic technology
1. Low-delay interaction
Real-time interaction means high real-time communication between the audience and the host, which is a prerequisite for a normal video call. Assuming that the timeliness is not good, it is easy to see that the audience of Lianmai receives the response 10 seconds after the anchor speaks, and this picture will feel very bad. You’ve got to go fast, you’ve got to pick a really good road, just like you drive and develop your career. When we want to transmit the video media stream, we have to choose the road, we have to test the network quality, we have to choose the fastest road with the best resources, and we have to run the fastest on that road. There are several steps along the way, including capturing audio and video, encoding, pushing, transcoding, distributing, pulling, decoding, and rendering. If the whole process is optimal, then you can have low latency.
Two, smooth stability
When the livestream hosts produce timely interactive content, they need to immediately deliver it to more audiences in the form of live broadcast. At this time, the fluency and clarity of the livestream content will directly affect the audiovisual experience of the audience. AnyRTC provides network jitter resistance and supports hardware codec capabilities to better ensure the listening experience. Bottom-up in-depth optimization of the terminal audio and video engine, including three links to combat network damage: jitter buffer, packet loss retransmission and forward error correction, as well as three modules of speech pre-processing: echo cancellation, noise suppression and automatic gain control.
Third, cross-platform interaction
When interactive live broadcasting becomes a common form of live broadcasting, no matter the audience or the anchor can initiate continuous mic between PC, mobile phone or even peripheral equipment to conduct real-time interaction in more scenes. Through deep optimization algorithm to ensure the efficiency and compatibility of codec, fully applicable to all mobile phone terminals, but also for specific mobile phone terminals, more intelligent hardware acceleration.
Common application scenarios of interactive Lianyamlive:
