1080i vs 1080p - Momwe Iwo Aliri Omwe Ndi Osiyana
1080i ndi 1080p zonsezo ndizopamwamba zofotokozera maonekedwe. Zizindikiro 1080i ndi 1080p zili ndi chidziwitso chomwecho, chikuyimira 1920x1080 kukonza pixel (1,920 pixels pamsewu ndi ma pixel 1,080 pansi pazenera). Komabe, kusiyana pakati pa 1080i ndi 1080p kumakhala momwe chizindikirocho chimatumizidwa kuchokera ku chipangizo cha magetsi kapena kuwonetsedwa pawindo la HDTV.
Mu 1080i, chithunzi chilichonse chajambula chimatumizidwa kapena kuwonetsedwa m'malo ena. Minda mu 1080i ili ndi mizere 540 ya pixels kapena mizere ya pixeliti ikuyenda kuchokera pamwamba mpaka pansi pa zenera, ndi minda yosamvetseka ikuwonetsedwa yoyamba komanso ngakhale minda yosonyezedwa yachiwiri. Palimodzi, minda yonse iwiri imapanga zowonjezera, zopangidwa ndi mizere yonse ya 1,080-pixel kapena mizere, iliyonse ya makumi atatu. 1080i amagwiritsidwa ntchito kwambiri ndi opanga ma TV, CBS, CW, NBC, ndi njira zambiri zamagetsi.
Kwa 1080p, chithunzi chilichonse chajambula chimatumizidwa kapena kuwonetsedwa pang'onopang'ono. Izi zikutanthauza kuti zonse zosamvetseka komanso zam'minda (mizere yonse ya 1,080-pixel kapena mizere ya pixel) zomwe zimapangidwa mwatsatanetsatane zimayikidwa sequentially, imodzi ikutsatira inayo. Chithunzi chomalizira chikuwoneka bwino kuposa 1080i, ndi zochepa zojambula zojambula ndi zowoneka m'mphepete. 1080p imagwiritsidwa ntchito kwambiri pa Blu-ray Discs ndi kusakasa kusankhidwa, chingwe, ndi mapulogalamu a satana.
Kusiyanasiyana M'kati mwa 1080p
Palinso kusiyana kwa momwe 1080p amasonyezera. Nazi zitsanzo zina.
- 1080p / 60 ikuyimira chimango chimodzimodzi mobwerezabwereza kawiri pa makumi atatu aliwonse. (chithunzi chowongolera chithunzi chavidiyo).
- 1080p / 30 ndi mawonekedwe omwewo omwe amasonyezedwa kamodzi pa makumi atatu aliwonse a wachiwiri. (muyeso wokhalapo kapena wolembedwera mawonekedwe a kanema.)
- 1080p / 24 ndi mawonekedwe omwewo omwe amasonyezedwa ma 24 onse a sekondi (firimu ya film film frame rate).
Kuti mumve zambiri momwe mafelemu a kanema amachitiridwira ndi kuwonetsedwa pa TV, tchulani nkhani yathu: Vuto la Pakanema ndi Vesi la Kuwunika Pulogalamu
Mfungulo uli mu Processing
Kugwiritsa ntchito 1080p kungapangidwe pamwambako ( upscaling DVD Player , Blu-ray Disc Player kapena media streamer), kapena zingatheke ndi HDTV chithunzicho chisanawonetsedwe.
Malingana ndi mphamvu yogwiritsira ntchito chipangizo chowunikira kapena TV ya 1080p , pangakhale kapena kusakhala kosiyana kuti TV iwononge mapeto (otchedwa deinterlacing) kutembenuza 1080i mpaka 1080p.
Mwachitsanzo, ngati TV ikugwiritsira ntchito pulojekiti yachitatu kapena ya homegrown, monga yomwe imagwiritsidwa ntchito pa LG, Sony, Samsung, Panasonic, ndi Vizio maselo, mwachitsanzo, akhoza kupereka zotsatira, zofanana, monga zotsatira mumagulu ambiri a zigawo. Kusiyanitsa kulikonse kungakhale kosaonekera kwambiri, kungowoneka pang'ono pokha pazithunzi zazikulu zowonekera.
Ojambula Ma CD 1080p ndi Blu-ray
Kumbukirani kuti pa Blu-ray, chidziwitso cha disk chiri mu 1080p / 24 maonekedwe (Zindikirani: Pali zina mwazinthu zomwe zimayikidwa pa Blu-ray disc mwina 720p / 30 kapena 1080i / 30, koma ndizosiyana, osati lamulo). Osewera ambiri a Blu-ray amatha kutulutsa 1080p / 24 ku TV yowoneka bwino. Makasitomala onse a Blu-ray ali othandizidwa ndi ndondomeko yothetsera 1080p / 30 ndi 1080/24. Izi zikutanthauza kuti ziribe kanthu kuti muli ndi TV yotani 1080p, muyenera kukhala bwino ngati wosewera mpira angathe kusintha chizindikiro cha 1080p / 30/60 kuti akwaniritse ma TV ena.
Komabe, pali kusiyana kwa momwe osewera ena amachitira ntchitoyi. Zotsatirazi ndi zitsanzo ziwiri zosangalatsa zomwe zidapangidwa kuchokera kwa osewera awiri omwe sakhala akupanga koma akugwiritsabe ntchito.
Chitsanzo choyamba ndi sewero la LG BH100 Blu-ray / HD-DVD (palibe kupanga) . Popeza, panthawi yomasulidwa, si ma HDTV onse omwe angasonyeze 1080p / 24, pamene LG BH100 imagwirizanitsidwa ndi HDTV yomwe ilibe ma input 1080p / 24 ndipo imatha kukhala ndi 1080p / 60/30 kapena 1080i , LG BH100 imatumiza chizindikiro chake cha 1080p / 24 kuchokera ku diski kupita ku pulojekiti yake yomwe imatulutsa chizindikiro cha 1080i / 60. Mwa kuyankhula kwina, osewera uyu akhoza kungopereka chizindikiro cha 1080p ngati TV ikugwirizana ndi 1080p / 24. Izi zimasiya HDTV kuti ichite gawo lomaliza la kuchotsa deinterlacing ndikuwonetsa chizindikiro cha 1080i chomwe chimabwera mu 1080p.
Chitsanzo china cha 1080p processing ndi Samsung BD-P1000 Blu-ray Disc Player (osapangidwanso) - zomwe zimachita ndi zovuta kwambiri. Blu-ray Player imawerenga chizindikiro cha 1080p / 24 kuchokera pa diski, kenako imayimiranso chizindikiro cha 1080i, kenako imatulutsa chizindikiro cha 1080i mkati mwake kuti ipange chizindikiro cha 1080p / 60 kuti chigwirizane ndi 1080p TV yabwino. Komabe, ngati zitha kuwona kuti HDTV silingathe kulemba chizindikiro cha 1080p, Samsung BD-P1000 imangotenga zizindikiro za 1080i ndipo imadutsa chizindikirocho mpaka HDTV, ndikulola HDTV kuchita china chilichonse.
Monga momwe zinalili ndi chitsanzo cha LG BH100 choyambirira. Chithunzi chomaliza cha 1080p chiwonetsero chimadalira chimene kuchotsa pulosesa kumagwiritsidwa ntchito ndi HDTV kwa sitepe yotsiriza. Ndipotu, mu Samsung, mwina HDTV imakhala yabwino kuposa 1080i-1080p deinterlacer kuposa Samsung, pomwe mungathe kuona zotsatira zabwino pogwiritsira ntchito deinterlacer yopangidwa mu HDTV. Ndipotu, mu Samsung, mwina HDTV imakhala yabwino kuposa 1080i-1080p deinterlacer kuposa Samsung, pomwe mungathe kuona zotsatira zabwino pogwiritsira ntchito deinterlacer yopangidwa mu HDTV.
Inde, onse a LG BH100 ndi Samsung BD-P1000 sali osiyana kwambiri ndi osewera kwambiri a Blu-ray disc, momwe angagwiritsire ntchito, nkhani 1080i / 1080p, koma ndi zitsanzo za momwe mafomu onsewa angasamalire, pa kuzindikira kwa wopanga.
1080p / 60 ndi PC Mapulogalamu
Ndikofunika kudziwa kuti pamene mutsegula PC ku HDTV kudzera pa DVI kapena HDMI , chizindikiro chowonetsera ma PC chikhoza kutumiza mafelemu 60 othawirapo pamsana uliwonse (malingana ndi magwero), mmalo mobwereza mawonekedwe omwewo kawiri, monga filimu kapena kanema zochokera ku DVD kapena Blu-ray Disc. Pankhaniyi, palibe zofunikira zowonjezera kuti zitheke kuti "pangani" mlingo wa 1080p / 60 pamtundu wotembenuka. Kuwonetsa makompyuta kawirikawiri sikukhala ndi vuto kulandira chizindikiro cha mtunduwu molunjika - koma ma TV ena akhoza.
Mfundo Yofunika Kwambiri
Mosasamala zomwe zimalowa mkati mwa chipangizo chanu kapena TV, momwe fano likuwonekera pa TV yanu ndilofunika. Kusakhalitsa kukhala ndi chitukuko chochokera kunja ndikuchita miyeso yeniyeni, kapena kuyerekeza zotsatira pogwiritsa ntchito ma TV ndi zigawo zowonjezera nokha, motalika HDTV yanu ili ndi processing 1080p mkati mumayikidwa.
Komabe, 1080i / 1080p siwo okhawo mawonekedwe otanthauzira apamwamba omwe mudzakumana nawo, muyenera kudziwa bwino kusiyana pakati pa 720p ndi 1080i , 720p ndi 1080p , ndi 4K .
