Apple Low-Latency HLS

The same simplicity, scalability, and quality of HLS — but faster. Wowza Streaming Engine with Apple Low-Latency HLS enables low-latency video streaming coupled with the high-quality of traditional HLS. Stream live and on-demand content to play natively on Apple mobile devices in 3 seconds or less while offering backward compatibility to existing clients. Provide a more interactive user experience to your audience, no matter the viewership size.


WebRTC provides browsers and mobile apps with real-time communications (RTC) capabilities via simple APIs. Traditionally known for peer-to-peer communications, utilizing Wowza Streaming Engine or Wowza Steaming Cloud, gives users the ability to scale beyond one-to-one or one-to few connections, distributing to an audience of any size, from hundreds to tens of thousands or more. This technology is becoming essential to the growing world of interactive live streaming.

Secure Reliable Transport

Wowza Streaming Engine and Wowza Streaming Cloud support the ingest of streams via SRT (Secure Reliable Transport)—an open-source technology designed to help you deliver high-quality, secure and low-latency video. SRT accounts for packet loss, jitter and fluctuating bandwidth, maintaining the integrity and quality of your stream.

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

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.
