Types of .M3U8 playlist.

Master playlist. It contains references to media playlists (typically same content with various bitrates). Also called "multivariant playlist" in recent versions of the HLS standard.
All other types of playlists are media playlists, they contain references to media segments.
- VoD playlist. A static media playlist for a fully recorded content. The list of media segments cannot change.
- Event playlist. A growing media playlist for a running event. It is possible to move backward in the event, up to the beginning. New media segments can be added at the end of the playlist. No segment can be removed.
- Live playlist. A sliding media playlist for a live channel, without backward browsing. The initial segments are regularly removed. New segments are regularly added at the end of the list.
