4K vs 1080p Kugereranya ubuziranenge
Imiyoboro yuzuye igufasha kumva 4k vs 1080p kugereranya ubuziranenge.
Gusobanukirwa Icyemezo: Urufatiro rwa tekiniki
Icyemezo cyerekana umubare wa pigiseli igize ishusho ya sisitemu cyangwa videwo, bigira ingaruka ku buryo burambuye kandi bisobanutse bigaragara kuri ecran. 1080p, izwi kandi nka Full HD, irimo pigiseli 1,920 itambitse kuri pigiseli 1,080 ihagaritse, yose hamwe igera kuri miliyoni 2.07. Iki cyemezo cyabaye igipimo cyibisobanuro bihanitse mu myaka irenga icumi kandi gikomeza gukoreshwa henshi kurubuga rwa interineti, imikino, na tereviziyo. 4K ikemurwa, tekiniki yitwa Ultra High Definition (UHD), ikubiyemo 3,840 kuri 2,160 pigiseli, yose hamwe igera kuri miliyoni 8.29. Ibi byerekana inshuro enye pigiseli ibara ya 1080p, niho izina rya “4K” rikomoka. Ubwinshi bwa pigiseli yiyongereye itanga ibisobanuro birambuye byafashwe kandi bikerekanwa, bigatuma bifite agaciro cyane cyane kuri ecran nini yo kureba, guhanga ibintu byumwuga, hamwe nibisabwa bisaba kubyara neza.
Ubwiza bugaragara nibisobanuro birambuye
Itandukaniro rigaragara hagati ya 4K na 1080p rigaragara cyane mugihe ureba ibiri kuri ecran nini cyangwa iyo wicaye hafi yerekana. Kuri ecran ya santimetero 50 nini, ibisobanuro birambuye mubirimo 4K birema amashusho atyaye cyane, hamwe no gusobanuka neza muburyo bwimiterere, imiterere yo mumaso, nibintu byiza nkimisatsi, imyenda, nibisobanuro birambuye. Ibi bisobanuro byongeweho bifite agaciro cyane cyane kuri documentaire ya kamere, ibiganiro bya siporo, hamwe na sinema aho ubudahemuka bugaragara. Nyamara, inyungu igaragara ya 4K biterwa cyane no kureba intera nubunini bwa ecran. Kuri ecran ntoya (munsi ya santimetero 32) cyangwa icyumba cyo kuraramo kireba intera (metero 8-10), ijisho ryumuntu rishobora guhatanira gutandukanya ibirimo neza 1080p na 4K. Ikibanza cyiza cyo gushima 4K ibisobanuro mubisanzwe bibaho iyo wicaye kuri metero 4-6 uvuye kuri santimetero 55 cyangwa nini. Byongeye kandi, ubuziranenge bwibikoresho byatanzwe hamwe nuburyo bwa kodegisi birashobora guhindura cyane itandukaniro rigaragara hagati yimyanzuro.
Ingano ya dosiye nububiko
Kubara inshuro enye za pigiseli zibarwa muri videwo ya 4K isobanura mu buryo butaziguye ubunini bwa dosiye nini, mubisanzwe kuva kuri 2,5 kugeza kuri 4 kurenza ibyo bihwanye na 1080p, bitewe na codec na compression ikoreshwa. Filime isanzwe 1080p irashobora gufata 4-8 GB yububiko, mugihe ibintu bimwe muri 4K bishobora gusaba 15-30 GB cyangwa birenga. Uku kwiyongera gutangaje kwubunini bwa dosiye bifite ingaruka zikomeye kubikorwa remezo byo kubika, gusubiza inyuma, no kohereza ibihe. Kubakora ibintu hamwe nababigize umwuga bakorana na dosiye ya videwo, ingaruka zo kubika zirenze ibisohoka byanyuma. Amashusho ya 4K, kwerekana intera hagati, hamwe numutungo wumushinga birashobora gukoresha vuba terabaýt yububiko. Isaha imwe yamashusho 4K idacometse kumashusho irashobora kurenga 500 GB, bigatuma igisubizo kibika neza kandi gikora neza dosiye ikora neza. Byongeye kandi, gukorana naya madosiye manini bisaba ibyuma bikomeye cyane kugirango uhindure neza kandi byihuse byo gutunganya byihuse byo gutanga no guhindura imirimo.
Umuyoboro mugari hamwe n’ibitekerezo bitemba
Gutemba ibintu 4K bisaba umurongo mugari kuruta 1080p, hamwe nibibuga byinshi byerekana umuvuduko wa interineti ntarengwa wa 25-35 Mbps kugirango uhuze 4K, ugereranije na 5-8 Mbps kuri 1080p. Umuyoboro mugari urashobora kuba ikibazo kumiryango ifite gahunda ya interineti igarukira, abakoresha benshi icyarimwe, cyangwa imiyoboro idahinduka. Netflix, kurugero, ikoresha hafi 3 GB kumasaha ya 1080p itemba ariko irashobora gukoresha GB 7 kumasaha kubirimo 4K. Kwiyongera kwagutse bisaba kandi bigira ingaruka kumiyoboro yo gutanga ibintu hamwe nibikorwa remezo. Abatanga isoko bagomba kuringaniza ubuziranenge hamwe nibishoboka, akenshi bagashyira mubikorwa imenyekanisha rihindagurika rihita rihindura imyanzuro ishingiye kumurongo mugari. Kubakoresha bafite caps ya data cyangwa gahoro gahoro ya enterineti, 1080p akenshi itanga uburambe bwokureba bwizewe nta bufferi nigitonyanga cyiza kijyanye no kwaguka kudahagije kumigezi ya 4K.
Ibisabwa Ibyuma no Guhuza
Kwerekana no gutunganya ibintu 4K bisaba ibyuma bikomeye cyane ugereranije na 1080p. Ikarita ya Graphics, itunganya, hamwe nibikoresho byerekana bigomba gushyigikira 4K ikemurwa kandi ifite imbaraga zihagije zo gutunganya kugirango ikemure amakuru yiyongereye. Ibyuma bishaje birashobora guhangana na 4K gukina, bikavamo amakadiri yataye, gutitira, cyangwa kudashobora gukina ibirimo na gato. Ikarita igezweho igezweho kugeza kumurongo wohejuru ushushanya amakarita asanzwe akora neza 4K gukina neza, ariko guhindura cyangwa gukora ibirimo 4K bisaba nibindi bisobanuro bikomeye byibyuma. Ubwuzuzanye burenze imbaraga zo gutunganya gusa gushyiramo ibipimo bihuza hamwe nubushobozi bwo kwerekana. Ibirimo 4K bisaba HDMI 2.0 cyangwa irenga, DisplayPort 1.2 cyangwa irenga, cyangwa ibipimo bihuza bihwanye kugirango bikomeze ubuziranenge bwuzuye. Ibikoresho bishaje, insinga, hamwe na disikuru ntibishobora gushyigikira ibipimo ngenderwaho, birashoboka kugabanya uburambe bwo kureba cyangwa bisaba kuzamura ibyuma. Byongeye kandi, bamwe mubakinyi bashaje bakina itangazamakuru, ibikoresho bitemba, hamwe na TV zifite ubwenge ntibishobora gushyigikira code ya 4K cyangwa bifite imbaraga zihagije zo gutunganya neza.
Umusaruro n’ibirimo Kurema Ingaruka
Gukora ibirimo muri 4K bisaba ibikoresho bihanitse, uhereye kuri kamera zishobora gufata amajwi 4K kugeza kuri sisitemu yo guhindura ifite imbaraga zihagije zo gutunganya nububiko. Kamera yabigize umwuga 4K muri rusange ihenze kurusha bagenzi babo 1080p, kandi ibikorwa byose byakozwe bigomba kuba binini kugirango bikemurwe bikenewe. Ibi birimo amakarita yo kwibuka byihuse, sisitemu ya mudasobwa ikomeye, hamwe nigihe kinini cyo gutanga ibisohoka byanyuma. Inyungu zo kubyara kurasa muri 4K zirenze gutanga gusa 4K ibirimo. Gufata amashusho muri 4K bitanga ubundi buryo bworoshye nyuma yumusaruro, kwemerera abanditsi guhinga, gukuza, no guhinduranya amafuti mugihe bagumana ubuziranenge bwa 1080p mubisohoka byanyuma. Ubu buhanga, buzwi nka “gukubita,” butanga neza kamera nyinshi za kamera kuva isoko imwe ya 4K. Byongeye kandi, gufata 4K bitanga ejo hazaza-kubintu bishobora gusubirwamo cyangwa gusubirwamo nkuko 4K ibyerekanwa bigenda bigaragara.

Nkeneye ibikoresho bidasanzwe byo gukina amashusho ya 4K?
Nibyo, 4K gukina bisaba ibyuma bihujwe harimo 4K ishobora kwerekana, insinga zikwiye (HDMI 2.0+ cyangwa DisplayPort 1.2+), nimbaraga zihagije zo gutunganya. Mudasobwa zishaje, abakinyi b’itangazamakuru, cyangwa TV ntibishobora gushyigikira 4K gukemura cyangwa birashobora guhangana no gukina neza.
Nakagombye gufata amashusho muri 4K nubwo nkeneye gusohoka 1080p gusa?
Kurasa muri 4K kubisohoka 1080p bitanga ibyiza byinshi harimo nubushobozi bwo guhinga no guhinduranya amafuti mugihe ukomeza ubuziranenge, ugaragaza ejo hazaza ibikubiyemo, kandi ufite ibikoresho byujuje ubuziranenge bishobora kuba remastering. Ariko, ibi bisaba umwanya wo kubika hamwe nimbaraga zo gutunganya.
Nangahe umuvuduko wa enterineti nkeneye rwose kuri 4K?
Serivise nyinshi zitanga inama zisaba 25-35 Mbps kugirango yizewe 4K, nubwo bamwe bashobora gukorana na 15-20 Mbps. Nibyingenzi kugira icyumba kinini cyumutwe kubindi bikoreshwa kuri interineti no kubara ihindagurika ryurusobe rushobora gutera buffer cyangwa ireme ryiza.
Ese kuzamura ireme kuva 1080p kugeza kuri 4K bifite akamaro nko kuva SD kugeza HD?
Mubisanzwe oya, gusimbuka kuva mubisobanuro bisanzwe ujya kuri HD (1080p) byari ibintu bitangaje kubantu benshi bareba kuruta gutera imbere kuva 1080p kugeza 4K. Iterambere rya 4K ni ryoroshye kandi riterwa cyane nuburyo bwo kureba, ingano ya ecran, hamwe nubwiza bwibikoresho. Inyungu zigaragara cyane hamwe na ecran nini hamwe no kureba kure.
