Low-Latency Formats and Protocols
Wowza supports nearly all common encoding formats and streaming protocols—many of which can be used to achieve low-latency streams. The format and protocol that are right for your use case depend on your scalability, interactivity and endpoint-compatibility needs.
Streaming Latency and Interactivity Continuum
Traditional Streaming Protocols
Traditional streaming protocols such as RTSP and RTMP can be used for low-latency streaming, but they don’t scale well, and are not natively supported on all endpoints (e.g., iOS devices). They work best for streaming to small to midsize audiences from a single media server.
Adaptive Streaming Protocols
Protocols such as HLS, HDS, HSS, and MPEG-DASH work well for streaming to large audiences on a wide range of devices at once, and are easily scalable. Historically, HTTP-Based Adaptive Streaming Protocols were not well suited for low-latency streaming, but the release of Low-Latency HLS, reduced-latency is now achievable.
Emerging technologies such as the WOWZ protocol, Apple Low-Latency HLS, low-latency CMAF for DASH, SRT, and WebRTC are designed for near-real-time audio, video and data delivery—even over less-reliable connections. These technologies are are ideal for use cases that require high degrees of interactivity and playback quality.
