1080i vs 1080p - Maitiro Azvo Akafanana Uye Akasiyana
1080i uye 1080p zvose zviri zviviri High Definition kuratidza mafomu. 1080i uye 1080p zviratidzo zvine ruzivo rwakadaro, zvinomiririra kusarudzwa kwe 1920x1080 pixel (1,920 pixels pasi pehwindo ne 1,080 pixels pasi pehwindo). Zvisinei, musiyano uri pakati pe1080i ne1080p uri munzira iyo chiratidzo chinotumirwa kubva kune imwe chinhu chigadzirwa kana kuoneswa pane chinyorwa cheHDTV.
Muna 1080i, vhidhiyo yega yega inotumirwa kana kuiswa mune dzimwe nzvimbo. Minda iri muna 1080i inoumbwa nemiromo 540 yepiksesi kana mitsara yepikseli inomhanya kubva kumusoro kusvika pasi pekona, neminda isinganzwisisi yakaratidzwa yekutanga uye kunyange minda inoratidzwa wechipiri. Pamwe chete, zvose zviri zviviri zvinoumba chimiro chakazara, chakaumbwa nemiromo ye-1,080-pixel kana mitsetse, yega yega yega yechipiri. 1080i inowanzoshandiswa nevashambadziri veTV, vakadaro CBS, CW, NBC, uye nemigwagwa yakawanda.
Pamusoro pe1080p, purogiramu imwe neimwe yevhidhiyo inotumirwa kana kuratidzwa zvishoma nezvishoma. Izvi zvinoreva kuti zvose zvisinganzwisisiki uye kunyange minda (dzose 1,080-pixel rows kana pixel mitsara) iyo inogadzira chimiro chakazara inofananidzwa sequentially, imwe inotevera imwe. Mifananidzo yekupedzisira yakaratidzwa inotarisa kutarisa kudarika 1080i, ine zvishoma zvigadzirwa zvekugadzira uye zvakagadzirisa mitsara. 1080p ndiyo inonyanya kushandiswa paBlu-ray Discs uye kusarudzwa kushandiswa, cable, uye satellite programming.
Kusiyanisa Mukati 1080p
Panewo kusiyana kwekuti 1080p inoratidzirwa sei. Heano mimwe mienzaniso.
- 1080p / 60 inomiririra chimiro chimwechete chinodzokororwa kaviri pamakumi matatu nerimwe rechipiri. (yakasimbiswa video video frame.)
- 1080p / 30 iyo purazi imwechete inoratidzwa kamwe chete yegumi neimwe yechipiri. (yakararama hupenyu kana kuti yakanyorwa video faira yepamusoro.)
- 1080p / 24 inoratidziro imwechete inoratidzirwa yese yechipiri yepiri yechipiri (mufambiro wefirimu firimu frame frame).
Kuti uwane mamwe mashoko pamusoro pekuti mafaira evhidhiyo anotorwa sei uye akaratidzwa paTV, tarisa nyaya yedu: Video Frame Rate ne Screen Refresh Rate
The Key in In Processing
1080p kushandiswa kunogona kuitwa pamusana ( upscaling DVD Player , Blu-ray Disc Player kana media streamer), kana kuti inogona kuitwa neHDTV pamberi pekuratidzwa kwechifananidzo.
Zvichienderana nekugadziriswa kwechinhu chemichina kana 1080p TV , panogona kunge kana kusakwanisa kuve nekusiyana kwekuita kuti TV iite yekugadzirisa kwekupedzisira (inonzi déinterlacing) danho rekutendeuka 1080i kusvika 1080p.
Semuenzaniso, kana TV iri kushandisa svondo rechitatu kana kuti pamba purogiramu, yakadai seyo inoshandiswa muLG, Sony, Samsung, Panasonic, uye Vizio sets, semuenzaniso, inogona kugovera zvakafanana, kana zvimwechete, zvigadziriswa sezvo shanduro dzinoshandiswa mune dzakawanda dzinowanika zvinhu. Kusawirirana kupi zvingave kwakajeka zvikuru, kungoonekwa zvishoma nezvishoma pamakona makuru ekunyora.
1080p uye Blu-ray Dhidhi Dhavhidzi
Ramba uchiyeuka kuti paBlu-ray, ruzivo rudhadhi ruri mu 1080p / 24 maitiro (Cherechedzai: Pane zvimwe zviitiko zvehupenyu zviri kuiswa paBlu-ray disc pane 720p / 30 kana 1080i / 30, asi avo izvo zvinopesana, kwete mutemo). Vakawanda vema-Blu-ray Disc vatambi vanogona kukwanisa kubudisa 1080p / 24 kuTV inoenderana neyomunhu. Vose vanenge vari vatambi veBlu-ray vanobvumirana nemhinduro 1080p / 30 uye 1080/24. Izvi zvinoreva kuti hazvinei pasinei neve terevhizheni 1080p yaunayo, iwe unofanirwa kunge wakanaka sezvo mutambi anogona kugadzirisa zviratidzo zvayo kusvika kune 1080p / 30/60 kuti agone maTV chaiwo.
Zvisinei, pane kusiyana kwekuti vamwe vatambi vanoita sei basa iri. Izvi zvinotevera mienzaniso miviri inonakidza yekare inobva kune vatambi vaviri avo vasiri kushandiswa asi vari muchiri kushandiswa.
Muenzaniso wokutanga ndeye LG BH100 Blu-ray / HD-DVD combo player (haisisiri mukugadzirwa) . Kubvira, panguva yekusunungurwa kwayo, haisi yose yeHDTV inogona kuratidza 1080p / 24, apo LG BH100 yakabatana neHDTV isina 1080p / 24 inopinza uye inoratidza kodzero asi ine 1080p / 60/30 kana 1080i inokwanisa , iyo LG BH100 inotumira mumiririri wayo 1080p / 24 kubva pane diski kusvika paneyo purogiramu yacho iyo inobva yatora chiratidzo che1080i / 60. Nemamwe mazwi, uyu mutambi anogona kungobudisa chiratidzo che 1080p kana TV iri 1080p / 24 inobatana. Izvi zvinosiya HDTV kuti iite danho rekupedzisira re deinterlacing uye kuratidza chiratidzo chinouya 1080i muna 1080p.
Imwe muenzaniso we 1080p processing ndiyo Samsung BD-P1000 Blu-ray Disc Player (haisisiri mukugadzirwa) - zvinodaro zvakanyanya kuoma. Uyu Blu-ray Player anoverenga chiratidzo che 1080p / 24 kubva padhidhi, zvino inowanzogarisa mucherechedzo kusvika kune 1080i, uye inobva deinterlaces yayo iri mukati yakaitwa zviratidzo 1080i kuitira kuti ipe chiratidzo che 1080p / 60 chekubudiswa kune 1080p inopinza terevhizheni yakakodzera. Zvisinei, kana ichiona kuti HDTV haigoni kuisa chiratidzo che 1080p, iyo Samsung BD-P1000 inongotora iyo pachake inogadzira zviratidzo 1080i uye inopfuurira ichi chiratidzo kusvika kuHDTV, ichiita kuti HDTV iite chero humwe hutano hwekugadzirisa.
Sezvakaitwa nemuenzaniso wekare weBHB100. Iyo yekupedzisira 1080p kuratidzira maitiro inobva pane izvo zvinoshandiswa pakubvisa deinterlacing zvinoshandiswa neHDTV yechitsika chokupedzisira. Zvechokwadi, mumatare eScams, zvingave kuti iHDTV inobatsira 1080i-10-1080p deinterlacer kupfuura yaSamsoni, apo iwe unogona kuona mugumisiro uri nani uchishandisa deinterlacer yakaiswa muHDTV.

Zvechokwadi, zvose LG BH100 ne Samsung BD-P1000 hazvisati zvichinyanya kufambiswa kune vatambi vakawanda veBlu-ray, maererano nemabatiro avo, 1080i / 1080p nhau, asi iyo mienzaniso yekuti zvose izvi zvigadziriswe zvingagadziriswa sei, pamusana pekugadzirwa kwechigadziri.
1080p / 60 uye PC Sources
Zvakakoshawo kuziva kuti paunoshandisa PC kuHDTV kuburikidza neDVI kana HDMI , zviratidzo zvinoratidza maPC zvinogona kunge zviri kutumira masayeri makumi matanhatu mashure ose (zvichienderana nemashoko), panzvimbo yekudzokorora mufananidzo wakafanana kaviri, sezvinoitwa mafirimu kana mavhidhiyo zvakabva kuDVD kana Blu-ray Disc. Muchiitiko ichi, hapana kuwedzerwa kushandiswa kunotarisirwa kuti "denga" 1080p / 60 purogiramu yemutengo kuburikidza nekushandurwa. Makombiyuta anotarisa kazhinji haana dambudziko kugamuchira rudzi urwu rwechiratidzo chekushandisa zvakananga - asi mamwe maTV anogona.
The Bottom Line
Pasinei nokuti chii chinopinda mukati memichina yako kana kuti TV, kuti sei chifananidzo chinotarisa paTV yako ndicho chakakosha. Nguva shoma yekuva ne tech inosvika uye ichiita zviyero chaiye, kana kuenzanisa zvigaro kushandisa maTV akasiyana uye zvikamu zvinowanikwa iwe pachako, kwenguva refu yako HDTV ine 1080p yekugadzirisa mukati uri kugadzirirwa.
Zvisinei, 1080i / 1080p haisi yega yepamusoro-sarudzo yekugadzirisa mafaira iwe uchasangana nawo, iwe unofanirawo kuziva kuti musiyano uri pakati pe 720p na 1080i , 720p uye 1080p , uye 4K .
