Question 1

What is WebRTC Simulcast?

Accepted Answer

WebRTC Simulcast enables a sender to publish several quality variants of the same video stream, each with different resolutions and bitrates. The viewer’s device or media server then selects the most suitable stream based on current network conditions.

Question 2

How does WebRTC Simulcast enhance video quality?

Accepted Answer

It reduces buffering and latency by continuously matching the video quality to the viewer’s available bandwidth and device capabilities.

Question 3

Can WebRTC Simulcast support gaming streams?

Accepted Answer

Yes. It enables game streams to adjust quality in real time, ensuring smoother viewing and reducing lag for users with limited bandwidth.

Question 4

Is WebRTC Simulcast more effective than Adaptive Bitrate Streaming?

Accepted Answer

For real-time interactions, Simulcast offers immediate quality adjustments, whereas Adaptive Bitrate Streaming is typically better suited to on-demand or pre-recorded content.

Question 5

How can WebRTC Simulcast performance be tested?

Accepted Answer

Tools such as Wireshark, WebRTC Internals, and browser developer consoles can be used to verify that multiple video layers are being transmitted and adapted correctly.
