Agora Interactive Live Streaming Premium enables one-to-many and many-to-many audio or video live streaming with the Agora RTC SDK.
Agora Interactive Live Streaming is different from Agora Video Call. In a video call, all users are the same role and can talk to each other freely. In an interactive live streaming, users can be the host or audience, where only the host can talk. For details, see this FAQ.
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 following table shows the differences between Agora live streaming products and traditional CDN live streaming:
|Agora Interactive Live Streaming Premium||Agora Interactive Live Streaming Standard||Traditional CDN live streaming|
|Typical scenarios||Live streaming events where the host(s) and audience have frequent audio and video interactions that require ultra-low latency on the audiences' clients.||Live streaming events where the host(s) must be able to respond quickly to the audience's text messages, comments, and virtual rewards or that require less frequent audio and video interactions.||Live streaming events that do not require audio or video interactions.|
|Latency||Latency on the audience's client: 1500 ms - 2000 ms||Latency on the audience's client: > 3000 ms|
