Umsebenzi
Ngaphezu kwalokho, i-interface ye-DVI ekhadini lemifanekiso i-interface ye-DVI-I, okuhlanganisa isignali yedijithali nesignali ye-analog.Ngakho-ke, amakhadi amaningi emifanekiso angenayo i-VGA interface angaguqulwa asuke esixhumi esibonakalayo se-DVI aye esixhumi esibonakalayo se-VGA nge-adaptha elula noma isiguquli sesignali.Izixhumanisi ze-DVI ne-HDMI ziyizixhumanisi zedijithali, ikakhulukazi amakhadi ezithombe anezixhumanisi ze-HDMI, ezisekela iphrothokholi ye-HDCP futhi abeke isisekelo sokubuka izinhlelo ze-HD ezinelungelo lobunikazi.Nokho, amakhadi ezithombe angenayo iphrothokholi ye-HDCP awakwazi ngokuvamile ukubuka amamuvi ane-copyright e-HD nezinhlelo ze-TV kungakhathaliseki ukuthi axhumeke kumamonitha noma i-TVS.
I-interface ye-DVI ihlukaniswe yaba izinhlobo ezimbili.Enye i-interface ye-DVI-D, engathola kuphela amasignali edijithali.Kunemigqa emi-3 kuphela kanye nemigqa engu-8 yezikhonkwane ezingu-24 kusixhumi esibonakalayo, phakathi kwayo iphinikhodi eyodwa ekhoneni eliphezulu kwesokudla ayinalutho.Akuhambisani nezimpawu ze-analog.
Enye i-interface ye-DVI-I ehambisana nazo zombili izimpawu ze-analog nedijithali.Ukuhambisana kwesignali ye-analogi akusho ukuthi i-interface ye-d-sub yesiginali ye-analog ingaxhunywa kusixhumi esibonakalayo se-DVI-I, kodwa kufanele isetshenziswe ngesixhumi sokuguqula.Ngokuvamile, ikhadi lemifanekiso elamukela lesi sixhumanisi lizoba nesixhumi esihlobene sokuguqula.
Ngenxa yezizathu zokusebenzisana, amakhadi ezithombe ngokuvamile asebenzisa imbobo ye-DVI-I, engaxhunywa embobeni evamile ye-VGA ngesixhumi sokuguqula.I-interface ye-DVI-D ngokuvamile isetshenziselwa abaqaphi abane-DVI, ngoba abaqaphi abanjalo nabo bane-VGA, ngakho abayidingi i-DVI-I enezimpawu ze-analog.Ngokuhlukile okumbalwa, abanye abaqaphi banamachweba we-DVI-I kuphela futhi awekho amachweba we-VGA.I-interface ye-DVI yemishini yokubonisa inezinzuzo ezimbili eziyinhloko ezilandelayo:
Shesha ngokushesha
I-DVI iwukudluliswa kwesiginali yedijithali, ayidingi ukuguqulwa, imininingwane yesithombe sedijithali izodluliselwa ngqo kudivayisi yokubonisa, ngaleyo ndlela inciphise inqubo yokuguqulwa kwedijithali kanye ne-analog ku-trival yenqubo yokuguqulwa kwedijithali, isindise kakhulu isikhathi, ngakho-ke kuyashesha, kuqedwe ngempumelelo lesi simo. ye-ghosting, i-DVI futhi isetshenziselwe ukudluliswa kwedatha, ukuncishiswa kwesignali, awukho umbala omsulwa, ocace kakhulu.
Ukuchazwa Okuphezulu Okuphezulu
Okudluliswa yikhompyutha ngaphakathi kuyisignali yedijithali kanambambili.Uma isixhumi esibonakalayo se-VGA sisetshenziswa ukuxhuma i-LCD, isignali idinga ukuguqulelwa ku-R, G, B isignali yombala oyinhloko kanye nesiginali yokuvumelanisa yomugqa nenkundla ngesiguquli se-D/A (idijithali/i-analog) ekhadini lemifanekiso.
Lawa masignali adluliselwa ku-crystal ewuketshezi ngemigqa yesignali ye-analog futhi isiguquli esihambisanayo se-A/D (i-analog/digital) siyadingeka ukuze kuguqulwe isignali ye-analog ibe isignali yedijithali futhi ngaphambi kokuba isithombe siboniswe kukristalu oluwuketshezi.Kule nqubo eshiwo ngenhla ye-D/A, A/D yokuguqulwa kanye nenqubo yokudlulisa isignali, ukulahlekelwa kwesignali kanye nokuphazamiseka nakanjani kuzokwenzeka, okuholela ekuhlanekeni kwesithombe ngisho nephutha lokubonisa.Kodwa-ke, isixhumi esibonakalayo se-DVI asidingi ukwenza lokhu kuguqulwa, ukugwema ukulahleka kwesignali, ukuze ukucaca kwesithombe nokuvezwa kwemininingwane kuthuthukiswe kakhulu.
Okokugcina, isixhumi esibonakalayo se-DVI singasekela iphrothokholi ye-HDCP, ibeke isisekelo sokubuka ividiyo ye-HD ene-copyright.Nokho, ukuze wenze ikhadi ihluzo ukwesekwa HDCP, optical DVI esibonakalayo akunakwenzeka, kudingeka ufake chip ozinikele, kodwa futhi ukhokhe high HDCP ukuqinisekiswa Imali, ngakho ukwesekwa ngempela HDCP protocol ihluzo ikhadi akuningi.
