I-1080i vs 1080p-Indlela abafana ngayo neyohlukeneyo
I-1080i kunye ne-1080p zizo zombini iifom zenkcazo ephakamileyo. Iimpawu ze-1080i kunye ne-1080p ziqulethe ulwazi olufanayo, olumele isisombululo se-pixel esingu- 1920x1080 (1,920 pixels kwisikrini ngamaphikseli angu-1,080 phantsi kwesikrini). Nangona kunjalo, umahluko phakathi kwe-1080i no-1080p usele ndlela isignali ithunyelwa kwisixhobo somthombo okanye siboniswe kwisikrini se-HDTV.
Ngo-1080i, isakhelo ngasinye sevidiyo sithunyelwa okanye siboniswe kwezinye iindawo. Amasimu e-1080i anemihlathi emi-540 yeepekseli okanye imigca yeepekseli eziqhubekela phezulu ukuya phezulu kwekhusi, kunye nemimandla engaqhelekanga iboniswe kuqala kwaye nakwiindawo eziboniswe okwesibini. Ngokubambisana, zombini iimihlaba zakha isakhelo esipheleleyo, esakhiwe kuyo yonke imigqa ye-1,080-pixel okanye imigca, yonke i-30 yesibini. I-1080i isetyenziswa ngokubanzi ngabasasazo beTV, njenge-CBS, i-CW, i-NBC, kunye neendlela ezininzi zekhebula.
I-1080p, ifomathi nganye yevidiyo ithunyelwe okanye iboniswe ngokuqhubekayo. Oku kuthetha ukuba zombini i-odd kunye neendawo (zonke ii-1,080-pixel imigqa okanye imigca ye-pixel) ezenza isakhelo esipheleleyo ziboniswa ngokulandelelana, enye ilandele enye. Umfanekiso wokugqibela ubonakaliswe ngokugqithiseleyo kunama-1080i, kunye neendawo zokuhamba ezimbalwa kunye neempembe. I-1080p isetyenziswa ngokuqhelekileyo kwi-Blu-ray Discs kunye nokusakaza okukhethiweyo, ikhebula kunye neprogram ye-satellite.
Ulwahluko phakathi kwe-1080p
Kukho ukwahlukana kwendlela 1080p iboniswa ngayo. Nazi ezinye izibonelo.
- I-1080p / 60 ibonisa isakhelo esifanayo ngokuphindaphindiweyo kabini kwi-30 yesibini. (izinga eliphakamileyo lwefom yevidiyo).
- I-1080p / 30 yinye isakhelo esifanayo esiboniswe kanye emva kwe-30 yesibini. (izinga eliqhelekileyo elikhoyo okanye elirekhodiweyo lereyithi yefom.).
- I-1080p / 24 yifom yesimo esifanayo esiboniswe yonke i-24 yesibini (isantya sefomati yefomati yefomati yesimo esifanayo).
Ukufumana iinkcukacha ezongezelelweyo malunga nendlela iifayile zevidiyo ezenziwa ngayo kwaye ziboniswe kwi-TV, bhekisa kwinqaku lethu: I-Frame Frame Rate kunye neResenti yokuHlaziya iSkrini.
I-Key is in Processing
Ukucutshungulwa kwe-1080p kunokwenziwa kumthombo ( upscaling DVD Player , Umdlali we- Blu-ray Disc okanye umgcini we-media), okanye unokukwenza nge-HDTV ngaphambi kokuba umfanekiso uboniswe.
Ngokuxhomekeke ekusebenziseni ukusetyenziswa kweso sixhobo seTV okanye i- TV ye-1080p , kukho okanye akukho mmahluko wokuba iTV iqhube ukucwangciswa kokugqibela (okubizwa ngokuba yi-deinterlacing) inyathelo lokuguqula i-1080i ukuya ku-1080p.
Umzekelo, ukuba iTV isebenzisa umntu wesithathu okanye iprojector yasekhaya, njengaleyo esetyenziswe kwi-LG, Sony, Samsung, Panasonic, kunye neeseti ze-Vizio, umzekelo, unokuvelisa okufanayo, okanye okufanayo, iziphumo njengoko abaprofeti basebenzisa kwiinkalo ezininzi zendalo. Naluphi na ulwahlulo lunokuba lubuqili, lubonakala luphawu oluthile kwizinto ezibukhulu zesikrini.
I-1080p ne-Blu-ray Disc Players
Gcina ukhumbule ukuba kwi-Blu-ray, ulwazi olukwidiski lukwifomathi ye-1080p / 24 (Qaphela: Kukho iziganeko zomxholo obekwa kwi-Blu-ray disc kwi-720p / 30 okanye nge-1080i / 30, kodwa ezo ziyiyo, kungekhona umthetho). Uninzi lwabadlali be-Blu-ray Disc banakho ukuvelisa i-1080p / 24 kwiTV ehambelana nayo kuloo fom yasekuhlaleni. Phantse bonke abadlali be-Blu-ray Disc bahambelana ne-1080p / 30 kunye ne-1080/24 yesisombululo. Oku kuthetha ukuba kungakhathaliseki ukuba yiyiphi iTV ye-1080p, kufuneka ulunge njengoko umdlali angakwazi ukuguqula umqondiso wesiphumo ukuya kwi-1080p / 30/60 ukulungiselela ii-TV ezithile.
Nangona kunjalo, kukho ukuhluka ngendlela abanye abadlali abafezekisa ngayo lo msebenzi. Ezi zilandelayo zimbini izihlandlo ezidlulileyo ezivela kubadlali ababini abangekho kwimveliso kodwa kusetyenziswa.
Umzekelo wokuqala ngumdlali we- LG BH100 we-Blu-ray / HD-DVD (engekho kwimveliso) . Ekubeni, ngexesha lokukhululwa, akuyiyo yonke i-HDTV engabonisa i-1080p / 24, xa i-LG BH100 ixhunyiwe kwi-HDTV engenayo i-1080p / 24 yokufakelwa kunye nokubonisa amandla kodwa ikwazi ukufakwa kwe-1080p / 60/30 okanye i-1080i , i-LG BH100 iyithumela ngokuzenzekelayo isalathisi sayo esingu-1080p / 24 ukusuka kwidiski ukuya kwiprojekthi yeprojekthi yevidiyo yona leyo ikhipha uphawu lwe-1080i / 60. Ngamanye amagama, lo mdlali unokuvelisa isalathisi esingu-1080p kuphela ukuba i-TV i-1080p / 24 iyahambelana. Oku kushiya i-HDTV ukuba yenze isinyathelo sokugqibela sokutshintsha i-deinterlacing nokubonisa isalathisi esingu-1080i engenayo kwi-1080p.
Omnye umzekelo we-1080p processing yi-Samsung BD-P1000 i-Blu-ray Disc Player (engekho kwimveliso) - into enzima kakhulu. Lo mdlali we-Blu-ray ufunda isalathisi esingu-1080p / 24 kwi-disc, kwaye ngokuqinisekileyo iphinda ikhuphe i-signal engama-1080i, ize idibanise i-signal yayo yangaphakathi eyenziwe ngu-1080i isalathisi ukwenzela ukudala isalathisi esingu-1080p / 60 kwisiphumo kwi-1080p input ithelevishini. Nangona kunjalo, ukuba ibona ukuba i-HDTV ayikwazi ukufaka isignali ye-1080p, i-Samsung BD-P1000 ithatha kuphela i-signal yayo eyi-1080i yangaphakathi iphinde idlulisele isignali ngokuya kwi-HDTV, ivumela i-HDTV ukuba yenze nayiphi na inkqubo yokwenziwa.
Kanye njengomzekelo wangaphambili we-LG BH100. Ifomati yokugqibela ye-1080p yokuxhomekeka kuxhomekeke kwinto eyenziwa yi-processor deinterlacing isebenzisa i-HDTV yesinyathelo sokugqibela. Enyanisweni, kwimeko ye-Samsung, mhlawumbi i-HDTV ethile ine-1080i-to-1080p deinterlacer engcono kuneS Samsung, apho ungabona umphumo ongcono ngokusebenzisa i-deinterlacer eyakhiwe kwi-HDTV. Enyanisweni, kwimeko ye-Samsung, mhlawumbi i-HDTV ethile ine-1080i-to-1080p deinterlacer engcono kuneS Samsung, apho ungabona umphumo ongcono ngokusebenzisa i-deinterlacer eyakhiwe kwi-HDTV.
Ngokuqinisekileyo, zombini i-LG BH100 kunye ne-Samsung BD-P1000 ayifani njengabadlali abaninzi be-Blu-ray disc, ngokubhekiselele kwindlela abaphatha ngayo, imiba eyi-1080i / 1080p, kodwa yimizekelo yeendlela zombini zezi fomathi zokusombulula zingalawulwa ngayo, ekuqaliseni komenzi.
1080p / 60 kunye nemithombo yePC
Kubalulekile ukuba uqaphele ukuba xa udibanisa i-PC kwi-HDTV nge- DVI okanye i-HDMI , isalathisi sokubonisa imifanekiso ye-PC sinokuthumela iifayile eziziingqondi ezingama-60 kwisibini (kuxhomekeke kwimithombo yendalo), endaweni yokuphindaphinda isakhelo esifanayo kabini, njengemifanekiso yefilimu okanye yevidiyo evela kwiDVD okanye i-Blu-ray Disc. Kule meko, akukho kuqhutyelwa phambili okufunekayo ukuba "udale" ireyithi ye-1080p / 60 yereyimu ngokuguqulwa. Ikhompyutheni ibonisa ukuba ayinayo ingxaki yokwamkela olu hlobo lombonakaliso ngokuthe ngqo-kodwa ezinye iiTV ziyakwazi.
Ngaphantsi
Kungakhathaliseki oko kungena ngaphakathi kwesixhobo sakho somthombo okanye iTV, indlela umfanekiso obukeka ngayo kwiTV yakho yinto ebalulekileyo. Umfutshane wokuba uphuhliso lwezobuchwepheshe kunye nokwenza imilinganiselo yangempela, okanye ukuthelekisa iziphumo usebenzisa iiTV ezihlukeneyo kunye nezixhobo zomthombo ngokwakho, ixesha elide i-HDTV yakho ine-1080p yokucwangcisa kwangaphakathi oyisetyenzisiweyo.
Nangona kunjalo, i-1080i / 1080p ayiyiyo kuphela ifomathi yesisombululo esiphezulu esiya kuhlangana nayo, kufuneka uqhelane nohlulo phakathi kwe- 720p no-1080i , 720p no-1080p , kunye no- 4K .
