Yiyiphi ividiyo ye-upscaling yintoni kwaye kutheni kubalulekile kwikhatywayo yasekhaya
Ngobuninzi beenkqubo kunye nemithombo yemithombo ukujonga kwi-TV yakho, kubalulekile ukuqaphela ukuba akukho yonke imithombo ene-video efanayo. Izimpawu ezingenayo ukusuka kusasazo / ikhebula / i-satellite / i-DVD / ukusasazwa, njl ... kungenakho ukulungiswa kwevidiyo efanayo kunye neTV yakho enokukwazi ukubonisa. Ukuze unikeze umgangatho ophezulu wokubukela kwimithombo eyahlukileyo, i-video upscaling ingafuneka.
Yiyiphi iVideo Upscaling
I-video upscaling yinkqubo ehambelana nemathematika yokubala kwepikseli yomkhiqizo wesignali ecacileyo okanye engekho ephakamileyo yevidiyo (njengeDVD eqhelekileyo, kwi-HD-satellite / satellite), kwi-pixel ebonakalayo ubale kwi-HDTV okanye iprojekti yevidiyo, enokuba yi- 1280x720 okanye i-1366x768 ( 720p ), i- 1920x1080 ( 1080i okanye i-1080p ), okanye i- 3840x2160 okanye i-4096x2160 ( ebizwa ngokuba ngu-2160p okanye i-4K ).
Yintoni oya kuyenza ngaphandle
Inkqubo yokuphakamisa ingaguquki ngokugqithisileyo isisombululo esincinane kwisisombululo esiphezulu - sisondele nje. Ngamanye amagama, umfanekiso ophakanyisiwe kwisisombululo esiphezulu awuyi kubonakala ifana nomfanekiso ovela kwisiqulatho esiphezulu kwindawo yokuqala.
Enye into ekufuneka iqwalaselwe kukuba nangona i-upscaling yenzelwe ukuphucula umgangatho womfanekiso wesigqibo se-video esisisombululo esingaphantsi, ukuba loo mqondiso iqulethe izinto ezongezelelweyo ezifakwe ngaphakathi, njengomsindo omncinci wevidiyo, umbala ombi, umgca obunzima, okanye ungeke uqiniseke, ividiyo iphakamisa Umprosesa unokwenza ukuba umfanekiso ukhangeleke ngakumbi, ngakumbi xa uboniswa kwizikrini ezinkulu, njengoko iimpazamo ezikhoyo kakade kwisigxina somthombo ziphakanyisiwe, kunye nomnye umfanekiso.
Ngokwemigaqo, oko kuthetha ukuthini xa i-DVD ephezulu kunye ne-DVD-quality sources ukuya kwi-1080p kunye ne-4K ingajonga kakuhle, i-upscaling imithombo yempawu engafanelekanga, njengeVHS (ngokukodwa ukurekhodwa kweefayile ze-EP, i-analog cable okanye isisombululo esiphantsi ukusasazeka).
Indlela Upscaling Yifezwa Ngayo Ekhaya YaseTheatre
Upscaling inokwenziwe yenziwe ngeendidi eziliqela zezinto. Ngokomzekelo, abadlali be-DVD abanemiphumo ye- HDMI nabo baye bazakhela kwi-upscaling ukuze iiDVD zibukeke zingcono kwi-HD okanye i-4K Ultra HD TV okanye iprojekti yevidiyo. Kwakhona kubalulekile ukubonisa ukuba bonke abadlali be-Blu-ray Disc baye bakha-kwividiyo upscaling ekuboneleleni ngokugqithiseleyo kumdlalo weDVD .
Kwakhona, uninzi lwama-middle-range kunye ne-high-end home-receivers receivers , ngaphezu kokuqhuba indima yabo njenge-switcher yomthombo, ukusetyenziswa kwee-audio, kunye ne-amplifier, inokubonelela ngevidiyo ekwakhiwe kwi-upscaling, kwaye, ngezinye iimeko, inikezela ukulungiswa komgangatho wesithombe izicwangciso ezifana noko ungakufumana kwiTV okanye iprojekti yevidiyo.
Ukongeza, ii-HD kunye ne-Ultra HD ze-TV kunye neeprojekti zevidiyo zinezixhobo zabo zeprojekti ezakhelwe ngaphakathi ezikwazi ukwenza imisebenzi yevidiyo ye-upscaling.
Nangona kunjalo, into enye ukugcina engqondweni ngokubhekiselele kwii-video upscalers kukuba akuyiyo yonke idalwe ilinganayo. Ngokomzekelo, nangona i-TV yakho inokubonelela ngevidiyo kwi-upscaling, i-DVD yakho okanye umdlali we-Blu-ray Disc unokukwazi ukwenza umsebenzi olungcono. Ngomfanekiso ofanayo, i-TV yakho inokwenza umsebenzi ongcono wevidiyo kwi-upscaling kuneyamukeli yakho yasekhaya.
Kuzo zonke iimeko, ngaphandle kweeTV kunye neeprojekti zevidiyo, ezihlala zihlala zikhona, i-video upscaling isebenza kwiDVD, i-Blu-ray Disc Player okanye i-receiver ye-home diservers iyakucinywa, ukuvumela ukuba izibonakaliso zomsombululo ezivela kumthombo ngamnye zibe engakhange afunyanwe aze afumane iTV.
Nangona kunjalo, ukuba ushiya umsebenzi wokuphucula umthombo wakho okanye i-home receiver reception, baya kugqitha ividiyo kwi-TV okanye iprojekti yevidiyo. Umzekelo, ukuba unayo i-TV ye-1080p kwaye iimpawu ezizayo zingama-1080p angabomthonyama okanye aphakanyisiwe ngaphambili ukuya kwi-1080p - i-TV ayifumani hlangothi.
Oku kusebenza nakwii-4K eziphezulu ze-HD ze-TV-ukuba isalathisi esingenayo sivela kwi-4K okanye isele ikhutshwe kwi-4K - yiloo nto oza kuyibona kwisikrini .
Ngaphantsi
Ukuba une-set-up equka i-1080p okanye i-4K Ultra HD ye-TV okanye iprojekti yevidiyo kwaye unomthombo wemvelaphi okanye ummkeli wecandelo lekhaya ongakwazi ukwenza imisebenzi ephakamileyo, kufuneka uthathe isigqibo sokuba yeyiphi imisebenzi engcono (ngamanye amagama ekhangeleka kakhulu kuwe) inokubeka isisombululo sesiphumo semveliso yamacandelo akho omthombo ngokufanelekileyo.
Ngokuqinisekileyo, kukho ezinye iimeko ezingaphezulu komgaqo njengoko ukuphela kwesiphelo se-1080p okanye i-4K Ultra HD yeTV kungakunika umbala owongezelelweyo okanye ukusetyenziswa komfanekiso kungakhathaliseki ukuba isisombululo sesignali esingenayo sinjani. Umzekelo, ngefomathi ye- Ultra HD ye-Blu-ray eyaziswa ngo-2016, kunye nemithombo emine yokusasaza, nayo ingaba ne- HDR kunye ne-Wide Color gamut ulwazi olufunekayo kwiTV ngaphambi kokubonisa imifanekiso.
