Det \u00e4r ett adaptivt kommunikationsprotokoll f\u00f6r streaming. Till en b\u00f6rjan anv\u00e4ndes HLS endast f\u00f6r Apple-enheter.  Nu st\u00f6ds det \u00e4ven av andra enheter, t.ex. Android-baserade smartphones. HLS fungerar genom att dela upp livestr\u00f6mmar i en sekvens av mindre HTTP-baserade filnedladdningar. Varje nedladdning laddar en liten del av en \u00f6vergripande potentiellt obegr\u00e4nsad transportstr\u00f6m. N\u00e4r str\u00f6mmen spelas upp kan klienten v\u00e4lja mellan flera olika alternativa str\u00f6mmar som inneh\u00e5ller samma inneh\u00e5ll kodat med en m\u00e4ngd olika datahastigheter. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Variabel datahastighet<\/h3>\n\n\n\n<p>Detta g\u00f6r att streamingsessionen kan anpassas till den tillg\u00e4ngliga datahastigheten. I b\u00f6rjan av streamingsessionen laddas en ut\u00f6kad M3U-spellista ned, som inneh\u00e5ller metadata f\u00f6r de olika understr\u00f6mmar som \u00e4r tillg\u00e4ngliga. Eftersom det \u00e4r en HTTP-baserad teknik kr\u00e4vs ingen streaming-server, s\u00e5 all omkopplingslogik finns p\u00e5 spelaren. HLS kan distribuera b\u00e5de on-demand och live videofiler.
