Yimuphi ividiyo upscaling futhi kungani kubalulekile ekhaya yaseshashalazini
Ngenqwaba yezinhlelo zokusebenza kanye nemithombo yokuqukethwe ukuze ubuke ku-TV yakho, kubalulekile ukuqaphela ukuthi akuwona wonke lawo mthombo anesinqumo esifanayo sevidiyo. Izimpawu ezingenayo kusuka kusakazwa / ikhebula / i-satellite / i-DVD / ukusakaza, njll ... kungenzeka ukuthi ingabi nesinqumo esifanayo sevidiyo ukuthi i-TV yakho ikwazi ukubonisa. Ukuze unikeze ikhwalithi yokubuka engcono kakhulu yemithombo ehlukene, ividiyo upscaling ingadingeka.
Iyiphi ividiyo yokuqeda i-Video
I-video upscaling yinqubo eyenza ngezibalo ngokulinganisela kwe-pixel kokukhipha isignali yevidiyo ejwayelekile noma engekho ephezulu-definition (njenge-DVD ejwayelekile, ikhebula le-HD / i-satellite, noma okuqukethwe okungenayo kwe-HD) kumaphikseli angokomzimba ebonakalayo ubale i-HDTV noma iprojector yevidiyo, okungaba yi- 1280x720 noma i-1366x768 ( 720p ), i- 1920x1080 (i- 1080i noma i-1080p ), noma i- 3840x2160 noma i-4096x2160 ( ebizwa ngokuthi i-2160p noma i-4K ).
Yikuphi ukukhuphuka okungawenzi lutho
Inqubo yokuvuselela ayiguquli ngokuyisimanga isinqumo esiphansi kwisinqumo esiphezulu - kuyisilinganiso nje. Ngamanye amazwi, isithombe esiphezulu esixazululweni esiphezulu ngeke sibonakale sifana nesithombe esivela kulowo mbono ophakeme kuqala.
Enye into okufanele ucatshangelwe yukuthi nakuba upscaling iklanyelwe ukuthuthukisa ikhwalithi yesithombe sezimpawu ezingezansi zokusakaza ividiyo, uma leyo signal isinezinto ezengeziwe ezifakwe ngaphakathi, njengomsindo wevidiyo oweqile, umbala omnyama, emaphethelweni aqinile, noma okungaqiniseki, ividiyo ephakanyisiweyo Iprosesa ingenza ngempela isithombe sibonakale sibi kakhulu, ikakhulukazi uma siboniswa esikrinini esikhulu, njengoba amaphutha asevele asesignini yomthombo adunyiswa, eceleni kwesithombe esisele.
Ngokweqile, ukuthi lokhu kusho ukuthini ngenkathi upscaling DVD kanye nemithombo yekhwalithi ye-DVD ku-1080p kanye no-4K kungabonakala kuhle, imithombo yamaspilisi empofu ephezulu, efana ne-VHS (ikakhulukazi ukuqoshwa okwenziwe ngesivinini se-EP, ikhebula le-analog, noma isinqumo esincane ukusakaza okuqukethwe) kungaletha imiphumela ehlanganisiwe.
Indlela Ukuguqulwa Kweqile Kubulawa Ngayo Ekhaya LwaseTheatre
Ukukhuphuka kwamandla kungenziwa yizinhlobo eziningana zezingxenye. Isibonelo, abadlali be-DVD abanemiphumela ye- HDMI nabo baye bakhalwa ngaphakathi ukuze ama-DVD abukeke kangcono ku-HD noma i-4K Ultra HD TV noma iphrojekthi yevidiyo. Kubalulekile ukuveza ukuthi bonke abadlali be-Blu-ray Disc baye bakhalwa ngaphakathi kwevidiyo ukuhlinzeka ngekhwalithi engcono ye-DVD yamazinga ajwayelekile .
Futhi, abaningi abasendaweni ephakathi nendawo ephezulu yokubukela i-home hall, ngaphezu kokufeza indima yabo njengomshini wokuguqula umthombo, ukucubungula umsindo, kanye nokukhulisa, kungase futhi unikeze ividiyo ekhishiwe ngaphakathi, futhi, kwezinye izimo, inikeze ukulungiswa kwekhwalithi yesithombe izilungiselelo ezifana nalokho ongayithola kwi-TV noma iphrojekti yevidiyo.
Ngaphezu kwalokho, i-HD ne-Ultra HD TV nama-projectors wevidiyo anezinhlelo zabo zokucubungula zevidiyo ezenza imisebenzi yevidiyo ye-upscaling.
Noma kunjalo, into eyodwa okumele uyikhumbule ngokubhekiselwe kumavidiyo we-video upscalers ukuthi akuzona zonke ezidalwa ezilinganayo. Isibonelo, nakuba i-TV yakho inganikeza ividiyo upscaling, i-DVD yakho noma Blu-ray Disc player ingakwazi ukwenza umsebenzi kangcono. Ngomfanekiso ofanayo, i-TV yakho ingenza umsebenzi ongcono wevidiyo upscaling kunokwamukela ekhaya yaseshashalazini.
Kuzo zonke izimo, ngaphandle kwama-TV namaphrosesa wevidiyo, abakwa-upscale abo abahlala njalo, imisebenzi ye-upscaling ye-DVD, i-Blu-ray Disc Player noma i-receiver yasekhaya yasendaweni ingavulwa, okuvumela ukuthi izibonakaliso zendabuko ezivela kumthombo ngamunye zibe ayitholakalanga aze afinyelele ku-TV.
Noma kunjalo, uma ushiya umsebenzi we-upscaling amadivaysi akho omthombo noma i-receiver reception ye-home, izobe iphakamisa ividiyo ye-upscaling ku-TV noma iprojekti yevidiyo. Isibonelo, uma une-TV engu-1080p futhi izimpawu ezizayo ziba ngu-1080p zendabuko noma zithunyelwe ngaphambilini ku-1080p - i-TV ayithathi hlangothi.
Lokhu kusebenza nakuma-4K Ultra HD TV - uma isignali engenayo ivela ku-4K noma isivele ikhishwe ku-4K - yilokho ozokubona esibukweni .
Okubalulekile
Uma une-setup ehlanganisa i-1080p noma i-4K Ultra HD TV noma iphrojekthi yevidiyo futhi unamakhemikhali omthombo noma umamukeli wendawo yaseshashalazini ongakwazi futhi ukwenza imisebenzi ye-upscaling, kufanele unqume ukuthi yimuphi umsebenzi ongcono (ngamanye amazwi ukuthi yini kubukeka kangcono kuwe) kungasetha isinqumo sokukhishwa kwevidiyo samakhi wakho omthombo ngokufanele.
Yiqiniso, kukhona okunye okungafani nomthetho njengoba ukuphela kwesiphetho se-1080p noma i-4K Ultra HD TV kunganikeza umbala owengeziwe noma ukucubungulwa kwesithombe kungakhathaliseki ukuthi ukuxazulula isignali okungenayo kuyini. Isibonelo, nge- HD HD ifomethi ye-Blu-ray Disc eyethulwa ngo-2016, kanye nemithombo ethile yokusakaza engu-4K, nayo ingase ibe ne- HDR nolwazi lwe-Wide Color gamut okuyinto i-TV okumelwe iyenze ngaphambi kokubonisa izithombe.
