For real-time broadcast of the video HTTP, find some relevant description today.

The original principle of implementation is still very simple, it is mainly to achieve a playlist refresh function:

The official documentation describes the following:

To play the stream, the client-obtains-Playlist file and
   then obtains and plays each media segment in the Pl Aylist.  It
   reloads the Playlist file as described in this document to discover
   additional segments.

The client follows the protocol and constantly refreshes the playlist list on the service side to perform real-time segment and video fragmentation.
