m3u8 / hls live event feed to use again and again

hey all,

my channel has a live feed and VOD. what I'm looking to do is have a spot that people can click on for live events.

my question is this... is there a proper term for an HLS/M3U8 link that I need that will work with roku that never changes so even if I do a live at 6 pm on Monday all I need to do is to start broadcasting on Friday without having to reload anything since roku already has the link ready to go?

the only thing I can find on Google is a static link.. not sure if that's what I'm looking for or not.

any help would be greatly appreciated
