Tsis tas li ntawd, DVI interface ntawm daim npav daim npav yog DVI-I interface, suav nrog cov teeb liab digital thiab analog teeb liab.Yog li ntawd, ntau daim npav daim npav tsis muaj VGA interface tuaj yeem hloov pauv los ntawm DVI interface mus rau VGA interface los ntawm ib qho yooj yim adapter lossis teeb liab converter.DVI thiab HDMI interfaces yog digital interfaces, tshwj xeeb tshaj yog cov ntawv teev lus nrog HDMI interfaces, uas txhawb nqa HDCP raws tu qauv thiab tsim lub hauv paus rau saib cov kev pabcuam HD.Txawm li cas los xij, cov ntawv teev lus uas tsis muaj HDCP raws tu qauv tsis tuaj yeem saib cov yeeb yaj kiab HD thiab TV programmes tsis hais seb lawv txuas nrog cov saib lossis TVS.
DVI interface muab faib ua ob hom.Ib qho yog DVI-D interface, uas tuaj yeem tau txais cov cim digital xwb.Tsuas muaj 3 kab thiab 8 kab ntawm 24 tus pins ntawm lub interface, cov uas ib tus pin nyob rau sab xis sab xis yog khoob.Tsis sib xws nrog cov teeb liab analog.
Lwm qhov yog DVI-I interface uas yog sib xws nrog ob qho tib si analog thiab digital signals.Analog signal compatibility tsis txhais hais tias d-sub interface ntawm lub teeb liab analog tuaj yeem txuas nrog DVI-I interface, tab sis yuav tsum tau siv los ntawm kev hloov pauv hloov pauv.Feem ntau, daim npav daim npav uas siv qhov kev sib tshuam no yuav muaj cov khoom sib txuas hloov dua siab tshiab.
Rau cov laj thawj sib xws, daim npav duab feem ntau siv DVI-I chaw nres nkoj, uas tuaj yeem txuas nrog lub chaw nres nkoj VGA li niaj zaus ntawm kev hloov pauv hloov pauv.Lub DVI-D interface feem ntau yog siv rau cov saib nrog DVI, vim hais tias cov saib no kuj muaj VGA, yog li lawv tsis xav tau DVI-I nrog cov cim analog.Muaj qee qhov tshwj xeeb, qee qhov saib tsuas muaj DVI-I chaw nres nkoj thiab tsis muaj VGA chaw nres nkoj.DVI interface rau cov khoom siv tso saib muaj ob qhov zoo hauv qab no:
Ceev ceev
DVI yog cov teeb liab kis tau tus mob, tsis xav tau kev hloov dua siab tshiab, cov ntaub ntawv duab digital yuav raug xa ncaj qha mus rau cov khoom siv, yog li txo cov digital thiab analog rau cov txheej txheem hloov pauv digital, txuag lub sijhawm, yog li nws nrawm dua, tshem tawm qhov tshwm sim zoo. ntawm ghosting, DVI thiab siv rau cov ntaub ntawv xa mus, teeb liab attenuation, tsis muaj xim ntau ntshiab, ntau vivid.
Ultra siab txhais
Dab tsi lub computer xa tawm sab hauv yog binary digital teeb liab.Yog tias VGA interface siv los txuas rau LCD, lub teeb liab yuav tsum tau hloov mus rau R, G, B thawj xim teeb liab thiab kab thiab teb synchronization teeb liab los ntawm D / A (digital / analog) converter hauv daim npav duab.
Cov teeb liab no tau xa mus rau cov kua siv lead ua kua los ntawm cov kab teeb liab analog thiab cov khoom siv A/D (analog/digital) converter yuav tsum tau hloov cov teeb liab analog rau hauv cov teeb liab digital dua ua ntej cov duab tuaj yeem tso tawm ntawm cov kua siv lead ua kua.Nyob rau hauv cov lus hais saum toj no D / A, A / D hloov dua siab tshiab thiab teeb liab kis tau tus mob, teeb liab poob thiab cuam tshuam yuav inevitably tshwm sim, ua rau cov duab distortion thiab txawm tso saib yuam kev.Txawm li cas los xij, DVI interface tsis tas yuav ua tiav cov kev hloov pauv no, tsis txhob poob lub teeb liab, kom cov duab pom tseeb thiab nthuav dav qhia tau zoo heev.
Thaum kawg, LUB DVI interface tuaj yeem txhawb nqa LUB HDCP raws tu qauv, tso lub hauv paus rau kev saib cov yeeb yaj kiab HD uas raug cai.Txawm li cas los xij, txhawm rau ua kom daim npav daim npav txhawb nqa HDCP, kho qhov muag DVI interface tsis tuaj yeem ua tau, yuav tsum tau nruab ib lub siab tawv nti, tab sis kuj them tus nqi HDCP authentication siab, yog li yeej txhawb HDCP raws tu qauv daim npav tsis ntau.
