ABOUT HLS - DEFINITION

▸ HTTP Live Streaming lets you send audio and video over HTTP from an ordinary web server for playback on iOS-based devices—including iPhone, iPad, iPod touch, and Apple TV—and on desktop computers (Mac OS X).

▸ HTTP Live Streaming supports both live broadcasts and prerecorded content (video on demand).

▸ HTTP Live Streaming supports multiple alternate streams at different bit rates, and the client software can switch streams intelligently as network bandwidth changes.

▸ HTTP Live Streaming also provides for media encryption and user authentication over HTTPS, allowing publishers to protect their work.

ABOUT HLS - HOW IT WORKS

The server component is responsible for taking input streams of media and encoding them digitally, encapsulating them in a format suitable for delivery, and preparing the encapsulated media for distribution.

GO HLS STREAMING

ABOUT HLS - HOW IT WORKS

The distribution component consists of standard web servers. They are responsible for accepting client requests and delivering prepared media and associated resources to the client. For large-scale distribution, edge networks or other content delivery networks can also be used.

ABOUT HLS - HOW IT WORKS

The client software is responsible for determining the appropriate media to request, downloading those resources, and then reassembling them so that the media can be presented to the user in a continuous stream.
