When selecting real-time streaming engine software for interactive educational content, consider features like low latency, scalability, support for adaptive streaming, interactive tools (e.g., chat, polls, quizzes), security measures (e.g., encryption), and compatibility with your Learning Management System (LMS) or educational platform. I recommend you to explore into Ant Media Server as a streaming engine software option . Its utilization of WebRTC technology for ultra-low latency streaming, scalability, and adaptability for on-premise or cloud deployment positions it as a strong contender in the market.
