M\u00e1lokto si v\u0161ak uvedomuje, \u017ee prehr\u00e1vanie videa je pomerne zlo\u017eit\u00fd proces, ktor\u00fd vyu\u017e\u00edva \u0161peci\u00e1lne kodeky. Mnoh\u00ed pou\u017e\u00edvatelia sa \u010duduj\u00fa, \u010do je kodek AV1 a pre\u010do ho potrebuj\u00fa, ke\u010f sa s n\u00edm stretn\u00fa.<\/p>\n\n\n\n
Mnoh\u00ed modern\u00ed pou\u017e\u00edvatelia maj\u00fa pomerne slab\u00fa predstavu o tom, ako funguj\u00fa r\u00f4zne programy a ich zariadenia. V minulosti, ke\u010f sa osobn\u00e9 po\u010d\u00edta\u010de za\u010dali objavova\u0165 v \u017eivote be\u017en\u00fdch \u013eud\u00ed, museli ich pou\u017e\u00edvatelia \u0161tudova\u0165 ich \u0161trukt\u00faru a funkcie ove\u013ea dlh\u0161ie a hlb\u0161ie.<\/p>\n\n\n\n
Dnes v\u0161ak u\u017e tak\u00e1to potreba nie je potrebn\u00e1. Modern\u00e9 opera\u010dn\u00e9 syst\u00e9my a po\u010d\u00edta\u010de s\u00fa navrhnut\u00e9 tak, aby boli \u010do najpr\u00edvetivej\u0161ie pre pou\u017e\u00edvate\u013eov. Dnes u\u017e \u013eudia nemusia \u0161tudova\u0165 funk\u010dnos\u0165 r\u00f4znych programov a opera\u010dn\u00fdch syst\u00e9mov, existuj\u00fa aplik\u00e1cie, v ktor\u00fdch m\u00f4\u017eete v\u0161etko urobi\u0165 doslova na p\u00e1r kliknut\u00ed.<\/p>\n\n\n\n
Ke\u010f sa teda \u013eudia stretn\u00fa s nezn\u00e1mymi pojmami, m\u00f4\u017ee ich to zmias\u0165. V\u00e4\u010d\u0161ina \u013eud\u00ed napr\u00edklad neust\u00e1le prehr\u00e1va r\u00f4zne vide\u00e1 alebo sleduje online vysielanie, ale len m\u00e1lo \u013eud\u00ed vie, \u010do je to kodek a pre\u010do je potrebn\u00fd.<\/p>\n\n\n\n
Kodek je \u0161peci\u00e1lne zariadenie alebo program, ktor\u00fd vykon\u00e1va funkcie konverzie d\u00e1t alebo sign\u00e1lu. To znamen\u00e1, \u017ee \u00fadaje sa najprv zak\u00f3duj\u00fa pomocou \u0161peci\u00e1lneho kodeku a potom sa ten ist\u00fd kodek pou\u017eije na ich dek\u00f3dovanie a pou\u017eitie. Patria sem aj videos\u00fabory alebo videoprenosy. V skuto\u010dnosti je video d\u00e1tov\u00fd tok, ktor\u00fd je \u0161peci\u00e1lne zak\u00f3dovan\u00fd do r\u00f4znych typov s\u00faborov.<\/p>\n\n\n\n
Preto mnoh\u00ed pou\u017e\u00edvatelia, ke\u010f sa stretn\u00fa s kodekom AV1, nech\u00e1pu, pre\u010do sa pou\u017e\u00edva a na ak\u00e9 s\u00fabory sa pou\u017e\u00edva.<\/p>\n\n\n\n
AV1 je kodek, ktor\u00fd umo\u017e\u0148uje komprimova\u0165 obrovsk\u00e9 mno\u017estvo d\u00e1t bez zn\u00ed\u017eenia kvality videa. To znamen\u00e1, \u017ee m\u00f4\u017ee by\u0165 ve\u013ekou v\u00fdhodou pre bud\u00face form\u00e1ty videa s vysokou sn\u00edmkovou frekvenciou, rozl\u00ed\u0161en\u00edm 8K, \u0161tandardmi HDR a po\u017eiadavkami na zvuk.<\/p>\n\n\n\n
To znamen\u00e1, \u017ee najv\u00fdraznej\u0161ia v\u00fdhoda tohto kodeku je pre streamovacie slu\u017eby, ako s\u00fa Netflix, Disney Plus alebo Hulu.<\/p>\n\n\n\n
Okrem toho, \u017ee kodek AB1 je univerz\u00e1lnym kompresn\u00fdm \u0161tandardom, umo\u017e\u0148uje jeho pou\u017eitie v mnoh\u00fdch \u010fal\u0161\u00edch aplik\u00e1ci\u00e1ch, ako s\u00fa videohry, aplik\u00e1cie v re\u00e1lnom \u010dase, napr\u00edklad videokonferencie, alebo v in\u00fdch programoch, v ktor\u00fdch sa pou\u017e\u00edvaj\u00fa videoprenosy.<\/p>\n\n\n\n
AV1 m\u00e1 by\u0165 n\u00e1stupcom form\u00e1tu HEVC (H.265), ktor\u00fd sa v s\u00fa\u010dasnosti pou\u017e\u00edva pre video 4K HDR. Tento form\u00e1t sa v s\u00fa\u010dasnosti nach\u00e1dza na platform\u00e1ch, ako s\u00fa Prime Video, Apple TV+, Disney Plus a Netflix.<\/p>\n\n\n\n
AV1 vyvinula Aliancia pre otvoren\u00e9 m\u00e9di\u00e1, ktorej \u010dlenmi s\u00fa spolo\u010dnosti Amazon, Apple, ARM, Facebook, Google, Intel, Microsoft, Mozilla, Netflix, Nvidia a Samsung.<\/p>\n\n\n\n
Medzi v\u00fdhody kodeku AV1 patr\u00ed predov\u0161etk\u00fdm skuto\u010dnos\u0165, \u017ee tento kodek nevy\u017eaduje licen\u010dn\u00e9 poplatky. To znamen\u00e1, \u017ee kodek AV1 je bez licen\u010dn\u00fdch poplatkov. To znamen\u00e1, \u017ee platformy, ktor\u00e9 bud\u00fa tento kodek pou\u017e\u00edva\u0165, sa m\u00f4\u017eu vyhn\u00fa\u0165 obrovsk\u00fdm licen\u010dn\u00fdm poplatkom na rozdiel napr\u00edklad od kodeku HEVC.<\/p>\n\n\n\n
Okrem toho kodek AV1 komprimuje \u00fadaje pribli\u017ene o 30 % efekt\u00edvnej\u0161ie ako jeho priami konkurenti. V bud\u00facnosti sa tak poskytne \u010fal\u0161\u00ed priestor na vkladanie \u010fal\u0161\u00edch zvukov\u00fdch a obrazov\u00fdch \u0161tandardov do s\u00faborov.<\/p>\n\n\n\n
Medzi hlavn\u00e9 nev\u00fdhody patr\u00ed v\u00fdrazne dlh\u0161\u00ed \u010das k\u00f3dovania videa. V niektor\u00fdch pr\u00edpadoch AV1 k\u00f3duje a\u017e 10-kr\u00e1t dlh\u0161ie ako jeho konkurenti.<\/p>\n\n\n\n
Ke\u010f v\u0161ak v\u00fdvoj\u00e1ri tento probl\u00e9m vyrie\u0161ia, s najv\u00e4\u010d\u0161ou pravdepodobnos\u0165ou sa tento kodek stane jedn\u00fdm z najob\u013e\u00fabenej\u0161\u00edch a najpou\u017e\u00edvanej\u0161\u00edch na svete.<\/p>\n","protected":false},"excerpt":{"rendered":"
