Digital Living Network Alliance (DLNA) je neziskov\u00e1 organiz\u00e1cia zalo\u017een\u00e1 v roku 2003. Jej hlavn\u00fdm cie\u013eom bolo vyvin\u00fa\u0165 \u0161tandardy, ktor\u00e9 umo\u017e\u0148uj\u00fa pohodln\u00e9 zdie\u013eanie digit\u00e1lnych multimedi\u00e1lnych s\u00faborov medzi zariadeniami v r\u00e1mci dom\u00e1cej siete, ako s\u00fa telev\u00edzory, po\u010d\u00edta\u010de, smartf\u00f3ny a \u010fal\u0161ie multimedi\u00e1lne zariadenia. T\u00e1to technol\u00f3gia bola mimoriadne d\u00f4le\u017eit\u00e1 koncom 2000. rokov a za\u010diatkom 2010. rokov, ke\u010f sa telev\u00edzory za\u010dali vybavova\u0165 sie\u0165ov\u00fdmi portmi, ktor\u00e9 umo\u017enili priame pripojenie k lok\u00e1lnym sie\u0165am. V\u010faka tomu bolo mo\u017en\u00e9 telev\u00edzory integrova\u0165 do dom\u00e1cich po\u010d\u00edta\u010dov\u00fdch siet\u00ed a sledova\u0165 vide\u00e1 bez priameho HDMI pripojenia.<\/p>\n\n\n\n

Ako DLNA funguje<\/strong><\/h2>\n\n\n\n

DLNA funguje v r\u00e1mci lok\u00e1lnej siete, kde v\u0161etky zariadenia musia ma\u0165 IP adresy v rovnakej podsieti (napr\u00edklad 192.168.1.10 a 192.168.1.20). V podstate ide o s\u00fabor protokolov navrhnut\u00fdch tak, aby umo\u017e\u0148ovali plynul\u00fa komunik\u00e1ciu medzi kompatibiln\u00fdmi zariadeniami v sieti.<\/p>\n\n\n\n

Na pou\u017e\u00edvanie DLNA je potrebn\u00fd server \u2014 zvy\u010dajne po\u010d\u00edta\u010d alebo NAS zariadenie (Network Attached Storage) so \u0161pecializovan\u00fdm softv\u00e9rom. Server preh\u013ead\u00e1va lok\u00e1lnu sie\u0165 a vyh\u013ead\u00e1va zariadenia podporuj\u00face DLNA. Po ich n\u00e1jden\u00ed sa vytvor\u00ed zdie\u013ean\u00e9 multimedi\u00e1lne prostredie, ku ktor\u00e9mu je mo\u017en\u00e9 pristupova\u0165 prostredn\u00edctvom funkci\u00ed ako \u201eZdie\u013eanie m\u00e9di\u00ed\u201c alebo \u201eDLNA server\u201c.<\/p>\n\n\n\n

Toto nastavenie umo\u017e\u0148uje pou\u017e\u00edvate\u013eom prehr\u00e1va\u0165 vide\u00e1, fotografie a in\u00e9 multimedi\u00e1lne s\u00fabory ulo\u017een\u00e9 v po\u010d\u00edta\u010di alebo NAS priamo na obrazovke telev\u00edzora. Pripojenie je realizovan\u00e9 prostredn\u00edctvom IP adries: server \u010d\u00edta medi\u00e1lne s\u00fabory a streamuje ich cez sie\u0165, zatia\u013e \u010do telev\u00edzor poskytuje rozhranie na prehliadanie a v\u00fdber po\u017eadovan\u00e9ho obsahu.<\/p>\n\n\n\n

Vzostup a \u00fapadok DLNA<\/strong><\/h2>\n\n\n\n

DLNA sa stala \u0161iroko roz\u0161\u00edrenou s n\u00e1stupom inteligentn\u00fdch telev\u00edzorov okolo roku 2010, \u010do v\u00fdrazne zjednodu\u0161ilo zdie\u013eanie lok\u00e1lnych m\u00e9di\u00ed. Pred DLNA museli pou\u017e\u00edvatelia zvy\u010dajne kop\u00edrova\u0165 vide\u00e1 na USB k\u013e\u00fa\u010de alebo prip\u00e1ja\u0165 po\u010d\u00edta\u010de k telev\u00edzorom pomocou HDMI k\u00e1blov. DLNA tieto nepr\u00edjemnosti odstr\u00e1nila t\u00fdm, \u017ee umo\u017enila prehr\u00e1vanie m\u00e9di\u00ed cez lok\u00e1lnu sie\u0165.<\/p>\n\n\n\n

Situ\u00e1cia sa v\u0161ak za\u010dala meni\u0165 po roku 2016 v d\u00f4sledku r\u00fdchleho rastu streamovac\u00edch slu\u017eieb. Ke\u010f aplik\u00e1cie inteligentn\u00fdch telev\u00edzorov poskytli pr\u00edstup k rozsiahlym kni\u017eniciam online obsahu, potreba lok\u00e1lne ulo\u017een\u00fdch m\u00e9di\u00ed \u2014 a t\u00fdm aj v\u00fdznam DLNA \u2014 za\u010dala klesa\u0165.<\/p>\n\n\n\n

Pokles popularity DLNA bol \u010falej ur\u00fdchlen\u00fd technol\u00f3giami ako Google Chromecast a Apple AirPlay, ktor\u00e9 umo\u017e\u0148uj\u00fa streamovanie obsahu na telev\u00edzor jedn\u00fdm kliknut\u00edm bez potreby nastavovania softv\u00e9ru medi\u00e1lneho servera. V d\u00f4sledku toho DLNA postupne stratila v\u00fdznam v prospech pou\u017e\u00edvate\u013esky pr\u00edvetivej\u0161\u00edch streamovac\u00edch technol\u00f3gi\u00ed.<\/p>\n\n\n\n

Pod\u013ea \u00fadajov DLNA Alliance bolo certifikovan\u00fdch viac ako 4 miliardy zariaden\u00ed s podporou DLNA. Nie je v\u0161ak jasn\u00e9, ko\u013eko z nich je st\u00e1le akt\u00edvne pou\u017e\u00edvan\u00fdch a ko\u013eko je zastaran\u00fdch alebo vyraden\u00fdch.<\/p>\n\n\n\n

Postupom \u010dasu v\u00fdrobcovia za\u010dali ukon\u010dova\u0165 certifik\u00e1ciu DLNA pre svoje produkty:<\/p>\n\n\n\n

    \n
  • Samsung ukon\u010dil certifik\u00e1ciu telev\u00edzorov v roku 2015 a mobiln\u00fdch zariaden\u00ed v roku 2016.<\/li>\n\n\n\n
  • LG ukon\u010dilo certifik\u00e1ciu telev\u00edzorov v roku 2016, hoci modely s podporou DLNA sa e\u0161te ur\u010dit\u00fd \u010das vyr\u00e1bali.<\/li>\n\n\n\n
  • Sony ukon\u010dila certifik\u00e1ciu v roku 2017.<\/li>\n\n\n\n
  • Panasonic nasledoval v roku 2019.<\/li>\n<\/ul>\n\n\n\n

    Na z\u00e1ver mo\u017eno poveda\u0165, \u017ee DLNA \u2014 kedysi spo\u013eahliv\u00e9 a \u0161iroko pou\u017e\u00edvan\u00e9 rie\u0161enie na zdie\u013eanie m\u00e9di\u00ed \u2014 sa postupne stalo zastaran\u00fdm, ke\u010f\u017ee jeho miesto prevzali modern\u00e9 streamovacie technol\u00f3gie. Napriek tomu niektor\u00ed v\u00fdrobcovia st\u00e1le zah\u0155\u0148aj\u00fa podporu DLNA vo svojich zariadeniach, hoci dnes je kv\u00f4li obmedzen\u00e9mu vyu\u017eitiu len zriedka propagovan\u00e1.<\/p>\n\n\n\n
