1080i vs 1080p - Indlela Efana Nayo Futhi Ehlukile
I-1080i ne-1080p kokubili amafomethi wokubonisa okuphezulu aphezulu. Izimpawu ezingu-1080i nezama-1080p ziqukethe ulwazi olufanayo, olumele ukulungiswa kwe-pixel ka- 1920x1080 (amaphikseli angu-1,920 kuwo wonke isikrini ngamaphikiseli angu-1,080 phansi kwesikrini). Kodwa-ke, umehluko ophakathi kuka-1080i no-1080p ukhona ngendlela isignali ithunyelwa ngayo kusuka kumshini womthombo noma kuboniswe kusikrini se-HDTV.
Ngo-1080i, ifreyimu ngayinye yevidiyo ithunyelwe noma iboniswe kwezinye izindawo. Amasimu e-1080i anamakhasi angu-540 wamaphikseli noma imigqa yamaphikseli asebenza phezulu ukusuka phansi kuze kube phansi kwesikrini, nezinsimu ezingavamile ziboniswa kuqala futhi ngisho nezinkambu ziboniswa okwesibili. Ngokubili, izinkambu zombili zakha uhlaka olugcwele, olwenziwe wonke imigqa engu-1,080-pixel noma imigqa, njalo ngamashumi amathathu nesikhombisa. I-1080i ivame ukusetshenziswa kakhulu ngabasakazo be-TV, njenge-CBS, i-CW, i-NBC, neziteshi eziningi zekhebula.
Ngo-1080p, uhlaka lwevidiyo ngalunye luhanjiswa noma luboniswa kancane kancane. Lokhu kusho ukuthi kokubili okungaqondakali ngisho namasimu (wonke imigqa ye-pixel engu-1,080-pixel noma imigqa yephikseli) eyenza ifreyimu egcwele ikhonjiswa ngokulandelana, enye ilandela enye. Isithombe sokugcina esibonisiwe sibonakala sibheke ngaphezu kuka-1080i, sinezinto ezimbalwa zokunyakaza kanye namaphethelo ahlangene. I-1080p isetshenziselwa kakhulu kuma-Blu-ray Discs nokusakaza okukhethiwe, ikhebuli, nokuhlelwa kwesathelayithi.
Umehluko Phakathi kuka-1080p
Kukhona futhi umehluko wokuthi u-1080p uboniswa kanjani. Nazi ezinye izibonelo.
- I-1080p / 60 imelela ifreyimu efanayo ephindaphindiwe kabili njalo ngemva kwe-30 yesibili. (izinga lokuphakama kwevidiyo elithuthukisiwe.)
- I-1080p / 30 iyisihlaka esifanayo esiboniswe kanye njalo nangama-30 wesibili. (isilinganiso esivela bukhoma noma sokurekhoda kwamarekhodi wevidiyo.)
- I-1080p / 24 yilapho ifreyimu efanayo iboniswa yonke imizuzu engu-24 yesibili (isilinganiso sokulinganisa isithombe sefrimu yefrimu).
Ukuze uthole imininingwane eyengeziwe yokuthi amafomethi wevidiyo asetshenziselwa kanjani futhi aboniswe ku-TV, bhekani esihlokweni sethu: I- Frame Frame Rate neViyo Yokuvuselela Isikrini
Isihluthulelo sisekucubunguleni
Ukucutshungulwa kwe-1080p kungenziwa emthonjeni ( upscaling i-DVD Player , i- Blu-ray Disc Player noma umsakazo wezindaba), noma ingenziwa nge-HDTV ngaphambi kokuba isithombe siboniswe.
Kuye ngokukwazi ukucubungula idivaysi yomthombo noma i- TV ye-1080p , kungase kube khona umehluko noma ukuthi ngeke kube khona umehluko wokuba i-TV yenza ukucubungula kokugcina (okubhekwa ngokuthi ukucutshungulwa) isinyathelo sokuguqula i-1080i kuya ku-1080p.
Isibonelo, uma i-TV isebenzisa inqubo yenkampani yangaphandle noma esekhaya, njengalezo ezisetshenziswa ku-LG, Sony, Samsung, Panasonic, ne-Vizio isethi, isibonelo, ingaveza imiphumela efanayo, noma efanayo, njengabacubungula asetshenzisiwe ezingxenyeni eziningi zemithombo. Noma yikuphi ukungafani kungase kube okucashile, kuphela okubonakalayo kumasayizi amakhulu esikrini.
I-1080p ne-Blu-ray Disc Players
Khumbula ukuthi ku-Blu-ray, ulwazi ku-disc lisefomethi ye-1080p / 24 (Qaphela: Kunezinye izimo zokuqukethwe okufakwa kwi-Blu-ray disc ku-720p / 30 noma ngo-1080i / 30, kodwa labo ahlukile, hhayi umthetho). Abaningi be-Blu-ray Disc abadlali banamandla okukhipha 1080p / 24 ku-TV ehambisanayo kulelo fomu langokwezifiso. Cishe bonke abadlali be-Blu-ray Disc bahambisana ne-1080p / 30 ne-1080/24 yokusungulwa kwesinqumo. Lokhu kusho ukuthi kungakhathaliseki ukuthi unjani i-TV engu-1080p, kufanele uhambe kahle njengoba umdlali angashintsha isignali yokukhipha ku-1080p / 30/60 ukuze afake ama-TV athile.
Noma kunjalo, kunezinhlobonhlobo zendlela abanye abadlali abafeza ngayo lo msebenzi. Okulandelayo yizibonelo ezimbili ezithakazelisayo ezedlule ezivela kubadlali ababili abangekho ekukhiqizeni kodwa basasebenza.
Isibonelo sokuqala isidlali se-LG BH100 Blu-ray / HD-DVD (ayisekho ekukhiqizeni) . Njengoba, ngesikhathi sokukhululwa, akuwona wonke ama-HDTV angabonisa i-1080p / 24, lapho i-LG BH100 ixhunywe kwi-HDTV engenayo ukufakwa kwe-1080p / 24 nokubonisa amandla kodwa ine-1080p / 60/30 kuphela noma i-1080i yokufaka amandla , i-LG BH100 isithumela ngokuzenzakalelayo isignali yayo engu-1080p / 24 kusukela ku-disc kuya kwiprojector yayo yevidiyo ephuma isuka isignali engu-1080i / 60. Ngamanye amazwi, lo mdlali angaphuma kuphela isignali engu-1080p uma i-TV ingu-1080p / 24 ehambisanayo. Lokhu kushiya i-HDTV ukwenza isinyathelo sokugcina sokukhipha futhi ukubonisa isignali engu-1080i engenayo ku-1080p.
Esinye isibonelo se-1080p processing yi-Samsung BD-P1000 Blu-ray Disc Player (ayisekho ekukhiqizeni) - lokho okwenzayo kuyinkimbinkimbi nakakhulu. Lo mdlali we-Blu-ray ufunde isignali engu-1080p / 24 ku-disc, bese empeleni uphinde uhambise isignali kuya ku-1080i, bese usulalisa isignali yakhe yangaphakathi eyenziwe ngu-1080i ukuze enze isignali engu-1080p / 60 yokukhishwa ku-1080p input ithelevishini enamandla. Kodwa-ke, uma kutholakala ukuthi i-HDTV ayikwazi ukufaka isignali ye-1080p, i-Samsung BD-P1000 isithatha isignali engu-1080i ngaphakathi yangaphakathi futhi idlulisela isignali ku-HDTV, ivumela i-HDTV ukuba yenze noma iyiphi inqubo eyengeziwe.
Njengoba nje nesibonelo sangaphambili se-LG BH100. Ifomathi yokugcina ye-1080p incike ekutheni i-processor deinterlacing isetshenziswa yi-HDTV yesinyathelo sokugcina. Eqinisweni, esimweni se-Samsung, kungenzeka ukuthi i-HDTV ethile ine-1080i-1080p deinterlacer engcono kune-Samsung, lapho kungenzeka ubone imiphumela engcono usebenzisa i-deinterlacer eyakhiwe kwi-HDTV. Eqinisweni, esimweni se-Samsung, kungenzeka ukuthi i-HDTV ethile ine-1080i-1080p deinterlacer engcono kune-Samsung, lapho kungenzeka ubone imiphumela engcono usebenzisa i-deinterlacer eyakhiwe kwi-HDTV.
Yiqiniso, kokubili i-LG BH100 ne-Samsung BD-P1000 ayifani nezebadlali abaningi be-Blu-ray disc, ngokuqondene nendlela abaphatha ngayo, izinkinga ezingu-1080i / 1080p, kodwa yizibonelo zendlela kokubili amafomethi okuxazulula angasetshenziswa, ngokuqonda komkhiqizi.
1080p / 60 kanye nemithombo ye-PC
Kubalulekile ukuqaphela ukuthi uma uxhuma i-PC kwi-HDTV nge- DVI noma i-HDMI , isignali yokubonisa ihluzo ye-PC kungenzeka ngempela ithumele amafremu ahlakaniphile angu-60 njalo kwesibili (kuye ngokuthi imithombo yomthombo), esikhundleni sokuphinda uhlaka olufanayo kabili, njengamafilimu noma ividiyo esekelwe kwi-DVD noma i-Blu-ray Disc. Kulesi simo, akukho ukucubungula okwengeziwe okudingekayo ukuze "udale" isilinganiso esingu-1080p / 60 uhlaka lohlaka ngokuguqulwa. Ukubukwa kwekhompyutha ngokuvamile akuyona inkinga yokwamukela lolu hlobo lwesignali yokufaka ngqo - kepha amanye ama-TV angase.
Okubalulekile
Kungakhathaliseki ukuthi yini engena ngaphakathi kwedivayisi yakho yomthombo noma i-TV, ukuthi isithombe sibheka kanjani i-TV yakho ebaluleke kakhulu. Okufushane kokuba ne-tech iphuma futhi yenza izilinganiso zangempela, noma uqhathanisa imiphumela esebenzisa ama-TV ahlukene nezinxenye zomthombo ngokwakho, isikhathi eside i-HDTV yakho ine-1080p yokucubungula kwangaphakathi oyisethiwe.
Kodwa-ke, ama-1080i / 1080p akuzona kuphela amafomethi okulungisa okucacile okucacile oyohlangana nawo, kufanele futhi wazi kahle umehluko phakathi kuka 720p no-1080i , 720p no-1080p , no- 4K .
