I-4K: kuyini futhi kufanele uyisebenzise njalo?
4K isixazululo, ebizwa nangokuthi i-4K, isho idivayisi yokubonisa noma okuqukethwe okunokulungiswa okuvundlile ngohlelo lwe-4,000. amaphikseli.
Kunezinqumo ezimbalwa ze-4K ezikhona emkhakheni wethelevishini yedijithali kanye ne-cinematography yedijithali. Embonini yokuqagela ama-movie, i-Digital Cinema Initiatives (DCI) iyindinganiso ehamba phambili ye-4K.
I-4K isiphenduke igama elijwayelekile lethelevishini esezingeni eliphezulu (UHDTV), nakuba ukulungiswa kwayo kungu-3840 x 2160 kuphela (nge-aspect ratio engu-16:9, noma 1.78:1), ephansi kunezinga lemboni yokuqagela ama-movie elingu-4096 x 2160 (nge-aspect ratio engu-19:10 noma 1.9:1 ).
Ukusetshenziswa kobubanzi ukuze kubonise ukucaca okuphelele kuphawula ukushintshwa kwesizukulwane sangaphambilini, ithelevishini enencazelo ephezulu, eyayihlukanisa imidiya ngokobukhulu obuqondile, njengokuthi 720p noma 1080p.
Ngaphansi komhlangano wangaphambilini, i-4K UHDTV izolingana no-2160p. I-YouTube kanye nemboni kamabonakude bamukele i-Ultra HD njengezinga layo le-4K, okuqukethwe kwe-4K okuvela kumanethiwekhi amakhulu kamabonakude kuhlala kunomkhawulo.
Kulokhu okuthunyelwe sizomboza:
Liyini iphuzu levidiyo ye-4K?
Nge-4K ungakwazi ukujabulela izithombe ezinhle ezingu-3840 × 2160 – ukulungiswa okuphindwe kane kwe-Full HD. Yingakho izithombe zibukeka zicacile futhi ziyiqiniso ngisho nakumabonakude wesikrini esikhulu, hhayi okusanhlamvu.
Izithombe eziguqulwe zisuka ku-4K ziye ku-HD Egcwele zinekhwalithi ephezulu nokulungiswa kunezithombe ezishuthwe nge-Full HD kusukela ekuqaleni.
Yikuphi okungcono: i-HD noma i-4K?
Ikhwalithi “ye-HD” enokulungiswa okuphansi amanye amaphaneli afinyelele phezulu ingu-720p, okungamaphikiseli angu-1280 ububanzi namaphikiseli angu-720 ukuphakama.
Ukulungiswa kwe-4K kuchazwa njengokuphindwe kane ukuxazulula kwe-1920 × 1080, evezwe enanini eliphelele lamaphikseli. Isixazululo se-4K singaba amaphikseli angu-3840×2160 noma angu-4096×2160.
I-4K inikeza isithombe esibukhali kakhulu kune-HD.

Ingabe kukhona okungahambi kahle ku-4K?
Ububi bekhamera ye-4K ngokuyinhloko ubukhulu bamafayela kanye neqiniso lokuthi ikhamera enjalo isetshenziswa kuphela ezikrinini ze-4K.
Amafayela amakhulu
Ngenxa yokuthi amavidiyo anekhwalithi ephezulu kangaka, lolo lwazi olwengeziwe kufanele futhi lugcinwe ndawana thize. Ngakho-ke, amavidiyo aku-4K nawo anosayizi wefayela omkhulu kakhulu.
Lokhu kusho ukuthi ngeke nje imemori khadi yakho igcwale ngokushesha, kodwa futhi uzodinga imemori disk eyengeziwe ngokushesha ukuze ugcine wonke amavidiyo akho.
Ngaphezu kwalokho, ikhompuyutha yakho kufanele ibe namandla anele okucubungula ukuze ikwazi ukuhlela amavidiyo akho nge-4K!

Iwusizo kuphela ezikrinini ze-4K
Uma udlala ividiyo ye-4K ku-Full HD TV, ividiyo yakho ayisoze yabonwa ngekhwalithi ephezulu.
Lokhu kusho nokuthi kufanele ube nesikrini se-4K ukuze ukwazi ukuhlela izithombe zakho ngekhwalithi yazo yoqobo.
