What is the difference between Agora Live Interactive Streaming and common CDN + RTMP technologies?
Most CDN + RTMP technologies for live streaming allow users to watch the live steaming in a web browser, which lowers the audience's threshold. Agora provides a solution for SD-RTN™, host, and audience to have the same real-time communication quality as an individual line with:
- Private voice and video coding
- Private transport protocol
- Private node deployment
- Private transmission algorithms
See the following table for details:
| Feature | CDN + RTMP | Agora Live Interactive Streaming |
|---|---|---|
| Video Encoding and Decoding | H.264 | Private |
| Audio Encoding and Decoding | AAC | Private |
| Transport Protocol | TCP based on RTMP | Private protocol based on UDP |
| Transmission Algorithm | TCP | Private algorithm for fixing packet loss and adjusting the bitrate automatically according to the current bandwidth |
| Picture-in-picture layout | Fixed | Can be adjusted dynamically |
Agora also enables the function of publishing streams into the CDN for social media sharing.
