Agora Live Interactive Video Streaming enables one-to-many and many-to-many audio or video live streaming with the Agora RTC SDK.
The difference between Agora Video Call and Agora Live Interactive Video Streaming is:
- Agora Video Call prioritizes smoothness and low latency. All users are the same role and can talk to each other freely. A typical scenario of Agora Video Call is a video conference call for many persons.
- Agora Live Interactive Video Streaming prioritizes high video quality. Users can be the host or audience, where only the host can talk. A user who wants to talk must change the role to a host. A typical scenario of Agora Live Interactive Video Streaming is an interactive online class.
Different from the traditional CDN live broadcast, which only allows one-way communication from the hosts to the audience, the Agora RTC SDK empowers the audience to interact with the hosts by becoming a host, like a viewer jumping onto the stage in the middle of a play to perform.
The Agora RTC SDK is applicable to scenarios that encourage active engagement, such as game-playing, online classes for students in small groups, and Q&A sessions during E-commerce live streaming. You can also use this SDK for one-to-one video calls that require high image quality.
