ApsaraVideo Live:Introduction to multi-host streaming

Last Updated:Dec 11, 2025

As live streaming latency continues to decrease, the traditional one-way streaming is no longer sufficient to meet the demand for real-time interaction. Multi-host streaming has emerged as a popular interactive feature, enabling engagement both within a single live room and between rooms. Powered by ApsaraVideo Real-Time Communication (ARTC) SDK and the stream relay to CDN feature, this solution adds powerful multi-host streaming capabilities to your application or platform.

Architecture

The host and guests use the ARTC SDK to publish their streams to a channel. The app server then calls a server-side API to relay the mixed stream from the channel to CDN. Audience can then watch the high-quality stream via the CDN.
