Ekugcineni i-Worlds ye-UHD ne-HDR Technology Technology Thola okucacile
Uma unesithakazelo esidlulayo ezweni elihamba phambili lokubuchwepheshe bezokuzijabulisa ekhaya uzokwazi ukuthi njengamanje sisenkathi yenguquko enkulu ngenxa yokufika kweyodwa kuphela kodwa ubuchwepheshe obusha bokubukwa kwevidiyo amabili : I- Ultra HD (eyaziwa nangokuthi i-4K) isinqumo , nebala eliphezulu eliphezulu (i-HDR) .
Izikrini ze-Ultra HD nokuqukethwe kunikeza ukulungiswa okuphindwe kaningi njenge-HD egcwele, kuyilapho okuqukethwe kwe-HDR (kuchaziwe ngemininingwane lapha) kunikeza ukukhanya okuthuthukisiwe, ukuphambene futhi, ekukhulumeni okuningi, ukusebenza kombala. Yize konke lokhu kuzwakale ngokuqondile ngokuqondile, iqiniso liwukuthi ikakhulukazi lapho i-HDR ikhathazekile khona ukuthi kungenzeka yini zonke izinhlobo zezindlela ezahlukahlukene zokukhona, nazo zonke izinhlobo zezimfanelo ezahlukene ze-HDR ukuze uthole indlela yokuya emakethe.
Futhi kuze kube yilapho nje abathengi babengenayo indlela ecacile yokuhlukanisa phakathi kokuhlangenwe nakho okuhle ngempela futhi okungenandaba neze-HDR etholakalayo. Siyabonga ukuthi lesi simo esibucayi siphethwe ngokucacile ngezinga elicacile ngesimemezelo sakamuva kulo mbukiso we-Consumer Electronics kuLas Vegas wenkampani ye-Ultra HD Premium.
Ukugqoka i-Ultra HD Premium Logo
Kuthuthukiswe iqembu le- Ultra High Definition Alliance (UHDA) lamaqembu angaphezu kwangu-30 omkhiqizo omqoka we-AV, i-Ultra HD Premium yakhelwe ukuhlinzeka abathengi ngendlela yokubuka ukuthi yiziphi i-TV nezokuqukethwe kwevidiyo ezenzelwe ukuletha ngempela i-HDR eqinile nokusebenza kwe-UHD.
Imikhiqizo kanye nokuqukethwe okuhambisana nesethi echazwe ngokucophelela kuzokwazi ukugqoka i-Ultra HD Premium logo, ngakho-ke uma umthengi ebona i-logo enamathele kumkhiqizo angaqiniseka ukuthi uzokwazi ukubanika izinga eliphezulu yokusebenza.
Kubalulekile ukucindezela ukuthi i-Ultra HD Premium logo kuyiqiniso kuphela uhlelo lokuncoma oludalwe yi-UHDA; akuyona izinga langempela ukuthi yonke imikhiqizo embonini ye-AV idinga ukuvumelana nayo. Ngamanye amazwi, kungenzeka ukuthi kuzoba nemikhiqizo ngaphandle lapho ikwazi ukugqoka ibheji le-Ultra HD Premium engenzi njalo ngoba ayithunyelwanga ku-UHDA ngezivivinyo ezidingekayo zokuqinisekisa. Noma kunjalo, noma yiluphi uhlobo lombhalo oluzosiza abathengi bakhethe indlela yabo ngokusebenzisa izingqinamba ezingase zibe khona zezwe le-UHD / HDR lingcono kunalutho.
Izakhi eziyinhloko zokucaciswa kwe-Ultra HD Premium zimi kanje.
Ama-TV namanye amadivayisi wevidiyo:
- Ukulungiswa kwesithombe: 3840x2160.
- Ukujula kombala: okungenani u-10-bit.
Umbala wokukhiqiza i- gamut : kufanele ukwazi ukusingatha ukumelelwa kombala we-BT.2020 '(uhlobo lwesitsha sokuthola ulwazi olubanzi lobubanzi bombala), futhi ubonise ngaphezulu kwezingu-90% zezinga eliphezulu lombala we-Digital Cinema Initiative P3 (izinga elijwayelekile elisetshenziselwa ukuhweba ama-cinema).
Ukuze i-High Dynamic Range idlale idivayisi kufanele isekele i-SMPTE ST2084 EOTF (umsebenzi wokudlulisela optical kagesi - indlela isikrini senza idatha yedijithali ibe ngukukhanya okubonakalayo) futhi ifinyelele ukuphakama kokuphakama okungaphezu kuka-1000 amantoni kanye namanki amnyama angaphansi kuka-0.05 nits, noma okungaphezu kuka-540 nits ukukhanya okukhulu kanye nezinombolo ezingaphansi kwezingu-0.0005 ezindaweni ezimbi kakhulu zezithombe.
Uma uzibuza ukuthi kungani kunikezwa izincomo ezimbili ezahlukene mayelana nokukhanya okuphezulu nokukhiqiza omnyama, kubalulekile ukubhekana nobuchwepheshe bokubukwa kwe-LCD no-OLED, ngoba bobabili bayakwazi ukukhiqiza ukusebenza okuhle kakhulu kodwa okuhlukile 'kwe-HDR'.
Ukusabalalisa nokuqukethwe kokuqukethwe:
- Ukulungiswa kwesithombe: 3840x2160
- Ukusebenza kombala: isignali encane ye-10-bit.
- Faka umbala wokukhiqiza i-gamut: BT.2020 ukumelwa kombala
- I-HDR: Kufanele usebenzise uhlelo lwe-SMPTE ST2084 EOTF HDR.
Ngaphezu kwalokho, i-UHD Alliance ikhuthaza ukucaciswa okulandelayo kokubonisa lapho udala amakhomitha okuqukethwe kwe-HDR: ubuncane obungamaphesenti angu-100 wezinga lemibala ye-P3; ukukhanya okukhulu kwezinombolo ezingaphezulu kuka-1000; kanye nokujula kwezinga elimnyama elingaphansi kwama-nithi angu-0.03.
Into eyodwa engabandakanyi imininingwane ye-UHDA ye-Ultra HD Premium yokusabalalisa okuqukethwe (okungahle kudidaniswe nezincomo zokwenza kahle ukubonisa) kunenani eliphansi nelinani eliphakeme lokukhanyisa, ngoba kubonakala sengathi kufaka phakathi lokhu kungavimbela abadali bokuqukethwe ukuba bakwazi ukuthola 'ukubukeka' okuqondile abafuna imibukiso ethile ye-TV namabhayisikobho.
