What is Ultra Low Latency Streaming

In the world of live streaming, latency is a pivotal factor that can make or break the viewer experience. Standard live video latency, typically around 30 seconds, can hinder interactions in dynamic scenarios such as live sports, financial trading, e-sports, and telemedicine.   

Castr’s Ultra Low Latency Streaming solution, empowered by cutting-edge WebRTC technology, overcomes these challenges by enabling sub-second latency. This breakthrough ensures a seamless, interactive streaming experience that keeps pace with real-time events.
