HTTP Live Streaming  (HLS) Executive Summary

HTTP Live Streaming (or HLS) is an adaptive streaming communications protocol created by Apple to communicate with iOS and Apple TV devices and Macs running OSX in Snow Leopard or later. HLS can distribute both live and on-demand files and is the sole technology available for adaptively streaming to Apple devices, which is an increasingly important target segment to streaming publishers.

HLS is widely supported in streaming servers from vendors like Adobe, Microsoft, RealNetworks, and Wowza, as well as real time transmuxing functions in distribution platforms like those from Akamai. The popularity of iOS devices and this distribution-related technology support has also led to increased support on the player side, most notably from Google in Android 3.0.

What kinds of device can playback HLS besides IOS devices? SunnyTV launch new HLS IPTV Set Top box SU_A9 and Su_A8 which can play HLS up to 1080P and less than 1 second while switching channels.

In the Apple App Store, if you produce an app that delivers video longer then ten minutes or greater than 5MB of data, you must use  HTTP Live Streaming, and provide at least one stream at 64Kbps or lower bandwidth. Any streaming publisher targeting iOS devices via a website or app should know the basics of HLS and how it’s implemented.

How HLS Works

At a high level, HLS works like all adaptive streaming technologies; you create multiple files for distribution to the player, which can adaptively change streams to optimize the playback experience. As an HTTP-based technology, no streaming server is required, so all the switching logic resides on the player.

To distribute to HLS clients, you encode the source into multiple files at different data rates and divide them into short chunks, usually between 5-10 seconds long. These are loaded onto an HTTP server along with a text-based manifest file with a .M3U8 extension that directs the player to additional manifest files for each of the encoded streams.
