Overview - iOS

Interactive Live Streaming (ILS) is a low-latency streaming solution designed for real-time engagement at scale. Unlike traditional streaming protocols like HTTP Live Streaming (HLS), which typically have a delay of 15–30 seconds, ILS offers latency as low as 300 milliseconds—making it ideal for experiences that rely on immediate interaction.

VideoSDK supports 100+ simultaneous hosts/co-hosts and 2,000+ real-time viewers. Need more? Contact support@videosdk.live.

ILS is not just about watching—it's about participating. While hosts and co-hosts can interact via audio/video and screen share, the audience watches in real time and takes part through interactive features like chat, polls and virtual gifting.

When to Use ILS?

Use Interactive Live Streaming when you need to:

• Run virtual events with multiple speakers
• Engage your audience actively during webinars
• Host fitness or coaching sessions with feedback

info

If your requirement is strictly one-way broadcasting where interactivity is minimal and latency isn't critical (e.g., sports highlights, pre-recorded shows), HTTP Live Streaming (HLS) may be more appropriate. To learn more about HLS, go through the documentation.
