Nekuuya kweHDTV (uye, munguva pfupi yapfuura, 4K Ultra HD TV ), kukurudzirwa kwezvikamu kuti zvienzane nekugadziriswa kwemaTV izvozvi zvinova kukosha. Sekugadzirisa, vazhinji vanowanikwa muDVD (avo varipo vachiripo) vakagadzirirwa "upscaling" kukwanisa kuenzanisa nekushanda kweDVD player nekwaniso yezuva ranhasi HD uye 4K Ultra HD TV.
Zvisinei, kuvapo kweBlu-ray disc format kwakanyongedza nyaya pamusoro pechirume pakati pekukwiridzirwa kweDVD yakawanda uye yezvokwadi yepamusoro yekunzwisisa Blu-ray.
Kuti uwane tsanangudzo yeDVD mavhidhiyo upscaling uye kuti yakabatana sei nechokuita vhidhiyo yakakurumbira, yakadai seBlu-ray, ramba uchiverenga ...
Standard DVD Resolution
Dhidhiyo inoenderana nehutano hwevhidhiyo ye 720x480 (480i). Izvi zvinoreva kuti kana iwe ukaisa diski muDVD player, ndicho chigadziro chokuti mutambi anoverenga kubva pa disc. Somugumisiro, DVD inoratidzirwa sehutano hwakagadziriswa.
Kunyange zvazvo izvi zvaive zvakanaka kana DVD yakarongeka muna 1997, nguva pfupi mushure mekusunungurwa kweDVD player vanoita sarudzo vakaita sarudzo yekuvandudza maitiro eDVD zvinyorwa kuburikidza nekushandiswa kwekuwedzerwa kushandiswa kune dhidhiyo reDVD mushure mekunge yaverengwa kubva padhidhi, asi isati yasvika vakasvika paTV. Izvi zvinotumidzwa seProgressive Scan .
Vashandi veDynamic scan DVD vanobudisa sarudzo imwechete (720x480) senzira isina kufambira mberi yakabvumira yakagadzirirwa DVD player, zvisinei, kupfuurira kupera kwakapa mufananidzo wakajeka.
Heano mufananidzo we 480i uye 480p:
- 480i inomiririra 720 mapikiseti anonatswa pahwindo pamiriyoni uye mazana 480 pixel pasi pasi pehwindo. Urongwa uhwu hunobereka miganhu 480 inopenya, iyo iyo, zvakare, yakaratidza zvimwe. Mune mamwe mazwi, mitsetse yose isingaoneki inoratidzirwa, inoteverwa nemitoo yese.
- 480p inomirira 720 pixels inoratidzwa mukati mehwindo nechokukwirira uye 480 pixels pasi pechiratidzo vertically. Urongwa uhwu hunoisa mitsara mazana mana yakatenderera pahwindo, iyo iyo, zvakare, yakaratidzwa zvishoma nezvishoma, kana imwe imwe mutsara inoratidzika inotevera imwe.
Nzira yeUpscaling
Kunyange zvazvo kuenderera mberi kwekutsvaga kwakagadziriswa mifananidzo yakajeka paTV dzakabatana, nekutumirwa kweHTTV, zvakakurumidza kuonekwa kuti kunyange zvazvo maDVD akangoita sarudzo ye 720x480, hutano hweavo mifananidzo hunogona kuvandudzwa nekuwedzera kuburikidza nekushanda nzira inonzi Upscaling.
Upscaling inzira inoshandiswa nemasvomhu inosvika pikisi yemuviri weiyo yakabudiswa neDVD signal kune pikisi yemuviri yepamusoro pane HDTV, iyo inowanzo 1280x720 (720p) , 1920x1080 (1080i kana 1080p), uye iye zvino, maTV akawanda ane 3840x2160 (2160p kana 4K) .
- 720p inomiririra 1,280 pixels inoratidzirwa pahwindo pakatarisana ne 720 pixels pasi pechirati chiri pasi. Urongwa uhwu hunoisa mitsara 720 yakakosha pahwindo, iyo iyo, zvakare, yakaratidzwa zvishoma nezvishoma, kana imwe mutsara inoratidzika inotevera imwe.
- 1080i inomiririra mapekisi esiriyoni 1,920 anoratidzirwa pahwindo rekuyera uye 1,080 pixel pasi pasi pehwindo. Urongwa uhwu hunobatsira 1,080 mitsara yakakoshesa, iyo iyo, zvakare, yakaratidza zvimwe. Mune mamwe mazwi, mitsetse yose isingaoneki inoratidzirwa, inoteverwa nemitoo yese.
- 1080p , inomiririra 1,080 mitsetse yakakosha yakaratidzwa sequentially. Izvi zvinoreva mitsetse yose inoratidzwa panguva imwecheteyo.
- 4K (kana 2160p) , kune rumwe rutivi, inomiririra 3 480 mitsetse yakakosha yakaratidzwa sequentially. Izvi zvinoreva mitsetse yose inoratidzwa panguva imwecheteyo. 4K ndiyo yepamusoro yepamusoro yeHD kuratidza maitiro.
Mhinduro Inobatsira yeDVD Upscaling
Maziso, pane musiyano muduku kune ziso revhareji yevatengi pakati pe 720p ne1080i . Zvisinei, 720p inogona kuunza mufananidzo unotarisa-kutarisa, nekuda kwekuti mitsetse nemapiksesi zvinoratidzwa mune imwe nzira inotevera, kwete pane imwe nzira yakafanana.
Iko kukwidziridzwa kunoita basa rakanaka rekufananidza nepamusoro pepikeleri yekubudiswa kweDVD player kumunhu wepacelel yekugadzirisa kuratidzwa kweterevhizheni yakananga yeHTTV, zvichiita kuti zvinyatsotsanangurwa uye ruvara ruvepo.
Zvisinei, upscaling, sezvairi ikozvino yakashandiswa, haigoni kuchinja maDVD mavhidhiyo echokwadi muzvokwadi yakadzama (kana 4K) mifananidzo. Zvechokwadi, kunyange zvazvo upscaling inoshanda zvakanaka neyakagadzirirwa pixel kuratidza, dzakadai sePlasma , LCD , uye OLED TV, zvigumisiro hazviwanzoenderana neCRT-based HDTVs (neropafadzo haisi yakawanda yeiyo iri kushandiswa).
Zvimwe Zvokuyeuka NezveDVD uye DVD Upscaling:
- Chero DVD chero ipi zvayo inogona kugadzirirwa kusvika kune HDTV. Kunyange zvazvo upscaling DVD players vari nani kukwanisa kuenzanisa nharaunda yepikeleri yekugadzirisa kweHDTV, unogona kuve nemigumisiro yakaisvonaka paDVD yakawanda player (isina kuwedzera kunyorera kana upscaling simba) yakabatana neHDTV yakapiwa Component kana S-Vhidhiyo mazano (Note : maTV akawanda mutsva haasisina S-mavhidhiyo maitiro).
