Ekugqibeleni iiHlabathi ze-UHD kunye ne-HDR iTeknoloji ye-TV Fumana okucacileyo
Ukuba unomdla ogqithisayo kwihlabathi elizihambelayo le-teknoloji yokuzonwabisa yasekhaya uya kukwazi ukuba njengangoku singaphakathi kwexesha elinguqulelo oluyingqungquthelayo ekufikeleleni kokungabikho komnye kodwa ubuchwepheshe obutsha bevidiyo : I- Ultra HD (eyaziwa nangokuthi i-4K) isisombululo , kunye nebala eliphezulu eliphezulu (HDR) .
Izikrini ze-Ultra HD kunye nomxholo zinika izigqibo ezine ngokubanzi njenge-HD ezipheleleyo, ngelixa i-HDR enomxholo (ichaziwe ngokucacileyo apha) inikeza ukukhanya okuphuculweyo, ukuchasene kwaye, kwiinkalo ezininzi, ukusebenza kombala. Nangona konke oku kuvezwa ngokucacileyo ngokuchanekileyo ngokusemgangathweni, inyaniso kukuba ngokukodwa apho i-HDR ixhalabangako kukho zonke iintlobo zezindlela ezahlukeneyo ezikhoyo, kunye nazo zonke iintlobo zeempawu ezahlukileyo ze-HDR ukuze zifumane indlela yazo kwindawo yokuthengisa.
Kwaye kwadlula ukuba abathengi bangekho ndlela ecacileyo yokuhlula phakathi kwezinto ezilungileyo kunye neentlobo ze-HDR ezingenakuthi zifumaneke. Ngombulelo lo mbandela otyumbileyo wanikezelwa ngokucacileyo kwizinga lokuchazwa kwangoko kwiseMboniselo yeMveliso yoMbane kwiLas Vegas yenkcazelo ye-Ultra HD Premium.
Ukugqoka i-Ultra HD Premium Logo
Uphuhliswe liqela leqela le- Ultra High Definition Alliance (UHDA) lamaqela angaphezu kwama-30 ase-AV AV, i-Ultra HD Premium yenzelwe ukubonelela abathengi ngeendlela zokujonga ukuba yeyiphi i-TV kunye nomxholo wevidiyo ezenzelwe ukunikela i-HDR eqinile kunye nokusebenza kwe-UHD.
Imveliso kuphela kunye nomxholo ohambelana nesethi ecacileyo yeenkcukacha kuya kuba nako ukugqoka uphawu lwe-Ultra HD Premium, ngoko ke ukuba umboleki ebona uphawu oluxhomekeke kwimveliso abanokuqiniseka ukuba luyakwazi ukuwanika izinga eliphezulu yentsebenzo.
Kubalulekile ukugxininisa ukuba i-Ultra HD Premium logo yinyaniso kuphela kwinkqubo yokuphakanyiswa eyenziwe ngu-UHDA; akuyona imilinganiselo yangempela ukuba yonke imveliso kwi-AV icandelo kufuneka ihambisane nayo. Ngamanye amazwi, kunokwenzeka ukuba kuya kuba nemveliso ngaphandle apho ikwazi ukumbathisa ibheji ye-Ultra HD Premium engenzi nto ngenxa yokuba ingeniswe kwi-UHDA yeziqinisekiso zokuqinisekisa iziqinisekiso. Sekunjalo, naziphi na izikhokelo zokunceda abathengi bakhethe indlela yabo ngokusebenzisa i-HD / HDR emhlabeni engcono kunanto.
Izinto eziphambili zeenkcukacha ze-Ultra HD Premium zilandelayo.
KwiiTV nakwiiWindows Devices:
- Ukulungiswa kwesithombe: 3840x2160.
- Ubuncinane bombala: ubuncinane ubuncinane be-10.
Umbala wokuvelisa i- gamut : kufuneka ukwazi ukuphatha ummeli we-BT.2020 '(uhlobo lwesitya kwi-wide range color information), kwaye ubonise ngaphezulu kwama-90% e-standard standard ye-Digital Cinema Initiative imibala yeP3 iidema).
I-High Dynamic Range idlala ifowuni kufuneka ixhase iS SMPTE ST2084 EOTF (umsebenzi wokutshintshisa oombane - ngendlela i-screen ijika ngayo idatha yedijithali ekukhanyeni okubonakalayo) kwaye ufezekise ukuphakama kokuphakama kwamanani angama-1000 kunye namanqanaba amnyama angaphantsi kwama-0.05. ngaphezu kwama-540 iinombolo eziphakamileyo kunye neenombolo ezingaphantsi kwama-0.0005 kummandla omnyama kakhulu.
Ukuba uyazibuza ukuba kutheni iziphakamiso ezibini ezihlukeneyo zinikwe ngokubhekiselele ekugqibeleni kunye nokuveliswa komnyama, kubalulekile ukubamba ubuchwepheshe bokubukeka kwesikrini seLCD kunye ne-OLED, kuba bobabini banakho ukuvelisa iimpawu ezigqwesileyo kodwa ezihlukeneyo ze-HDR.
Ukuhanjiswa kweNkcazo kunye nokuPhatha:
- IsiGqibo soMfanekiso : 3840x2160
- Ukusebenza kombala: isalathisi esincinci se-10-bit.
- Umbala wokuvelisa i-gamut: BT.2020 ukumelwa kombala
- I-HDR: Kufanele usebenzise inkqubo ye-SMPTE ST2084 ye-EOTF HDR.
Ukongezelela, i-UHD Alliance icebisa ukucaciswa okulandelayo kokubonisa xa udala abaphathi be-HDR: ubuncinci be-100% yomgangatho we-P3; ukukhanya kobuninzi beemithi ezili-1000; kunye nobunzulu bomgangatho obumnyama ombalwa kunama-0.03.
Into enye engabandakanywa kwi-UHDA ye-Ultra HD Premium iinkcazo zokuhanjiswa komxholo (ukuba ungadideki kunye neengcebiso zokubonisa iimpawu) zincinci kunye nezona ziphezulu zokukhanya, kuba zivelelwe ukuba ezi zinto ziyakuthintela abadali bokuqukethwe ukuba bakwazi ukufumana 'ukujonga' ngokusemthethweni bafuna imiboniso ethile yeTV kunye namabhayisikobho.
