Uma ukhethaIkhebula le-HDMI, sivame ukubona ilebula ethi “1080P.” Isho ukuthini ngempela? Lesi sihloko sichaza ngokuningiliziwe.
1080Piyindinganiso yefomethi yethelevishini yedijithali esezingeni eliphezulu kakhulu echazwe yi-Society of Motion Picture and Television Engineers (SMPTE). Isixazululo sayo sokubonisa esisebenzayo siyi1920 × 1080, ngenani lamaphikseli elipheleleIzigidi ezingu-2.0736Ikhwalithi ephezulu yesithombe enikezwa yi-1080P inikeza abathengi ulwazi lwangempela lomsindo nokubukwayo olusezingeni lemidlalo yaseshashalazini yasekhaya. Ngenxa yokuthi ihambisana ngokuphelele nezinye izinhlobo ze-HD, iyaguquguquka kakhulu futhi isebenza kabanzi.
Enkambisweni yokwenza kube yidijithali, ukwenza kube yidijithali ngendlela efanayo kungenye yezinyathelo ezibaluleke kakhulu. Ngokombono ogxile kubathengi, ipharamitha eqondakala kakhulu yileukucaca kwesithombeI-SMPTE ihlukanisa amasignali e-HDTV edijithali ngokusekelwe ezindleleni zokuskena zibe1080P, 1080I, kanye ne-720P (iimelei-interlace, futhipimeleokuqhubekayo).
I-1080P ibhekisela kufomethi yokubonisa efinyelelaIsixazululo esingu-1920 × 1080 sisebenzisa ukuskena okuqhubekayo, okumele ukuhlanganiswa okuphelele kobuchwepheshe bokuthwebula izithombe ze-cinema yedijithali kanye nobuchwepheshe bekhompyutha.
Ukuze siqonde ngokucacile i-1080P, kumele siqale sichaze i-1080i kanye ne-720P. Zombili i-1080i kanye ne-720P ziyizindinganiso zethelevishini zedijithali ezisezingeni eliphezulu eziqashelwa emhlabeni wonke. Amazwe ayesebenzisa uhlelo lwe-NTSC ekuqaleni asebenzisa uhlelo lwe-NTSC.1080i / 60Hzifomethi, ehambisana nemvamisa yasensimini kamabonakude we-NTSC analog. Ngokuphambene nalokho, iYurophu, iShayina, nezinye izifunda ezazisebenzisa uhlelo lwe-PAL ekuqaleni zasebenzisa1080i / 50Hz, ifana nemvamisa yensimu kamabonakude ye-analog ye-PAL.
Ngokwe720P, kwaba yindinganiso yokuzikhethela ngenxa yokubandakanyeka okujulile kwabakhiqizi be-IT embonini yethelevishini futhi kusukela lapho sekuthole ukuthandwa kumadivayisi okudlala i-HDTV asebenzisa ama-disc optical njengendlela eyinhloko yokuxhumana. Kufanele kuqashelwe ukuthiI-1080P iyindinganiso yangempela, ukuthi kuyakwenzaakukhona kuphela ku-60Hz, nokuthiI-1080P ayifani ne-FULL HD.
Ngakho-ke kuyiniI-HD Egcwele?
I-FULL HD ibhekisela kumathelevishini anephaneli eyisicaba angakwazibonisa ngokugcwele amaphikseli angu-1920 × 1080, okusho ukuthiisinqumo somzimba (sendabuko) singu-1920 × 1080Ukuze kuzuzwe imiphumela emihle kakhulu yokubuka lapho ubuka izinhlelo ze-HDTV, kudingeka ithelevishini ye-FULL HD. Kubalulekile ukuqaphela ukuthi i-FULL HD ayifani nomqondo "we-1080P" owafunwa abakhiqizi abaningi esikhathini esidlule.
Okubizwa kanjaloUsekelo lwe-1080Pkusho ukuthi ithelevishini ingakwaziyamukela futhi ucubungule amasignali evidiyo angu-1920 × 1080, kodwa i-TV ngokwayo ayinaso ngempela isinqumo esibonakalayo esingu-1920 × 1080. Esikhundleni salokho, ilinganisa isithombe esingu-1920 × 1080 sibe yisinqumo sayo sangempela ngaphambi kokusibonisa.
Isibonelo, i-I-TV ye-LCD engama-intshi angu-32kungaba nesinqumo sendabuko se1366 × 768, kodwa incwadi yayo yemiyalelo ingase ithi isekela i-1080P. Lokhu kusho ukuthi ingamukela isignali engu-1920 × 1080 bese iyiguqula ibe yi-1366 × 768 ukuze iboniswe. Kulokhu, i-“1080P” ibhekisela ku-okufakwayo okuphezulu okusekelwayo noma ukulungiswa kwesibonisi, okubonisa ukuthi i-TV ingamukela isignali engu-1920 × 1080, kodwa iyayitholahhayiyibonise kulelo sinqumo eliphelele.
