Umbukeli wanamuhla awusamangazi isithombe esiphethweni se- Full HD, ngakho lobu buchwepheshe bubuyiselwa yi-4K (i-Ultra HD). Amathelevishini ngesinqumo se-4K akhiqiza ikhwalithi yesithombe ezingeni elisha lonke. Manje ikhwalithi yesithombe kufomethi entsha isuke kabili kangcono, ngoba inani lamaphikseli liye landa ngokuya kusukela ngo-1920 kuya ku-4000! Masifunde kabanzi mayelana nobuchwepheshe obusha nobuchwepheshe obusisekelayo. Ngokuyinhloko, mayelana namaTV amasha ngesinqumo se-4K (i-Ultra HD).
Ifomethi ye-4K
Uma ubheka isinqumo esisha se-4K kusuka ohlangothini olunengqondo, khona-ke amandla amancane esibuko esikrinini (4000 * 2000) ngeke asondele uma ebuka i- TV ekhaya . Yiqiniso, okusanhlamvu kwesithombe esikrinini esinjalo kungakhohlwa kuze kube phakade, kodwa sekukhona umphumela obonakalayo owehlayo - lokho okubizwa ngokuthi ukugcoba. Emva kwakho konke, uma uhambisa isithombe kulokhu kwesikrini esinezincomo ezingaphansi kuka-3-4 (iziteshi eziningi zekhebula ze-TV), bese ugcwalisa sonke isikrini, idivayisi kufanele "isule" i-pixel ngayinye yesithombe ibe yiyodwa. Kusukela lokhu, izinga lezithombe lizohlupheka kakhulu, umehluko uzolahleka. Yiqiniso, ubuchwepheshe bamadivayisi obusekela isinqumo esingu-4K, kuzobe sekufunwa, kodwa, cishe, kamuva. Ngempela, eqinisweni, manje akukho okuqukethwe okwanele ongayibheka ku-TV yakho entsha nge-4K ukwesekwa. Kodwa akuwona konke okubi kakhulu. Uma kunezizathu zokuthi kungani kungakuzuzisa ukuthenga le TV, sizozicabangela.
Izinzuzo zamaTV 4K
Ukubukeka kwaleli fomethi kwajabulisa kakhulu abadlali abadlala imidlalo yokudlala emakhompyutheni abo. Kuze kube manje, kukhishwe imidlalo eminingana eyeseka ifomethi entsha yesithombe. Futhi noma yimuphi omunye umdlalo kulesi sikrini uzobukeka ucacile futhi uqobo. Kakade, kunamaphakheji akhethekile we-Full HD TV (isibonelo, eRussia), okusho ukuthi kunethemba lokuthi iziteshi zizovela maduzane ngekhwalithi engu-4K. Isixazululo esinjalo siyobe sesilungele emaphaketheni amakhulu e-plasma (angaphezu kwamasentimitha angu-84), ngoba uma isinqumo sincane, ama-pixel ayabonakala. Ukurekhoda ividiyo kule fomathi, bahlela ukusebenzisa ama-disc-Blu-ray ama-discs amathathu oseduze esikhathini esizayo esiseduze. Yebo, kungezansi, ngoba ividiyo kulesi sikhundla izodinga imidiya enamandla, futhi lo mdlalo uzoba namandla ka-100 GB. Lokhu kusho ukuthi maduzane ukuthenga i-movie kule fomethi kwidiski ngeke kube nzima kunokuba idrayivu yeDVD evamile. Ngenkathi wonke umuntu ofuna ukuqhubeka egoqa ukuthenga i-TV ye-4K, kufanelekile ukulinda lapho ezoba eshibhile, ngoba intengo yabo manje isibhakabhaka-phezulu. Amamodeli "amaningi enkululeko" we-TV yalesi sifundo manje abiza u-$ 5,000, futhi lokhu kufakwe ngamasentimitha angu-55. Kodwa ngalokhu konke, imishini yobuchwepheshe kanye nekhwalithi yokuqapha i-TV ngokwayo ngokuqinisekile! Embuzweni wokuthi uthenge i-TV ye-4K manje, ungaphendula: yebo, kunjalo, kodwa kuphela uma lokhu
Yini ongayifaka kule ngenhla? Ifomethi ye-4K inamandla amakhulu, ngoba kungekudala kakhulu wonke umuntu wahleka ngokusobala ifomethi yefomethi ephelele ye-HD ne-3G, kodwa emva kweminyaka embalwa lobu buchwepheshe buyingxenye ebalulekile yokuphila okuningi. Iyini ikusasa lesinqumo se-4K? Impendulo yaziwa futhi, kodwa kuze kube manje ukuthengwa kwe-TV enjalo kungcono ukulinda. Kodwa-ke, ithemba lokunciphisa amanani amanani akufanelekile, ngoba izikrini nama-matrixes asekela ukuxazulula okunjalo akunakwenzeka ukuthi angabizi kakhulu.
