Subscribing
With a stream Provision available from the Stream Manager and multiple variant broadcasts being streamed (either through using a Media Encoder or the Transcoder), subscribing to an Adaptive Bitrate controlled stream is rather straight forward, though differs slightly between each playback target of WebRTC, Flash and HLS.
Once the subscriber stream has started playback the stream will be dynamically upgraded or downgraded based on network conditions. How each playback target requests and handles the dynamic stream switching differs between them and is detailed in the following sections.
