Ukuvikelwa nokuphepha kokuqukethwe kwedijithali kuyinselele emphakathini wanamuhla. Kulesi sihloko uzokwazi yini i-HDCP, uhlelo lokukhiya oluvimbela ubugebengu bokuphanga.
Yini i-HDCP?
I-HDCP yisichasiselo se-High-BandWidth Digital Protection, emele ukuvikelwa kokuqukethwe kwedijithali ephezulu. Lobu buchwepheshe bakhiqizwa yi-Intel, njengomkhiqizo ohamba phambili futhi inelayisense yokusetshenziswa. Ngale ndlela, ngokusebenza kwayo, kuyadingeka imvume yeDijithali Yokuvikelwa Kokuqukethwe, okuyinkampani ephethwe yile nkampani.
Inhloso yalo enkulu ukuvikela okuqukethwe komsindo nevidiyo kwidijithali okune-copyright, futhi okwabiwa ngezintambo ezithile noma ngamathuluzi athile kuthelevishini. Lokhu kuxhumana kufaka izintambo ze-HDMI ne-DVI, ne-DisplayPort ne-Digital Visual Interface. Ngenkathi amadivayisi noma imithombo kungabadlali be-DVD, abadlali be-Blu Ray Disc namakhompyutha.
Ukuze ufunde kabanzi ngalokhu kuxhumana, ungafunda i-athikili izesekeli zekhompyutha.
Ngakolunye uhlangothi, i-HDCP isuselwa esidingweni sezinkampani ukuvimbela okuqukethwe ukuthi kukopishwe ngaphandle kwemvume yabo, noma ekurekhodweni ngaphandle kokulahlekelwa ikhwalithi yangempela.
Ngamafuphi, i-HDCP iyithuluzi lobuchwepheshe noma uhlelo lokuvimba oluzama ukuvimbela ubugebengu bokuqukethwe, ngokusungulwa kwamakhodi athile, womphakathi nawangasese.
Ukuqonda okuthe xaxa mayelana nokuthi yini yini i-HDCPNgemuva kwalokho sizobona ezinye izici ezihlobene.
Isebenza kanjani?
Okokuqala, ukuze umsindo noma ividiyo ikhiqizwe kabusha, kudingeka umthombo noma umfundi, isibonelo, uhlobo oluthile lwesidlali sokuqukethwe kwedijithali noma ikhompyutha, nohlelo lapho okuqukethwe okushiwoyo kungabukwa khona, okuvamise ukuba ngumabonakude.
Ngokuyinhloko, umthombo kufanele uxhumeke esikrinini ngekhebula le-HDMI noma le-DVI nge-HDCP, ukuze kuqhathaniswe ikhodi ehambisanayo.
Ngemuva kwalokho, uma umthombo ubona ukuxhumeka kwe-HDCP kwenye idivayisi, ivumela isignali ukuthi idlalwe ngokubethela kwedatha ethunyelwe. Ngakho-ke, amadivayisi ahambisanayo kuphela angaxhunywa.
Ekugcineni, uma ikhebuli noma idivayisi ingahambelani ne-HDCP, isistimu izokhiqiza uhlobo oluthile lwephutha, njengokunye kokulandelayo:
Okokufaka kwe-HDMI akutholakali kusistimu yomsindo. Awukho umsindo ovela ohlelweni lomsindo. Yize kukhona ukuxhumana, ukudluliswa kwesiginali akunakwenzeka. Isistimu yokubonisa noma isistimu yomsindo ayisebenzi, noma ivuliwe.
Izimo
Njengoba kuyithuluzi elinelayisense, ukuze ulisebenzise, ​​kufanele kubhekwe ukucatshangelwa okuthile:
Okokuqala, umsebenzisi kufanele akhokhe imali yonyaka futhi amukele imibandela yenkontileka yelayisense.
Phakathi kwezidingo ezibekwa kumsebenzisi njengengxenye yokwamukelwa kwemigomo, lezo eziphathelene nokuzibophezela okufanele babe nakho ukuvimba amaqembu ukuthi angalingisi okuqukethwe, kanye nokuqinisekisa ukuvikelwa kwawo, kudla kakhulu.
Yize isikhombimsebenzisi se-HDCP singakhethwa, imishini ezokwamukela okuqukethwe iyadingeka ukusekela lobu buchwepheshe.
nebubi
Ngaphandle kwezinhloso ezinhle ze-HDCP, inezinkinga ezithile. Phakathi kwabo, okulandelayo kugqama:
Iveza ukwehluleka kaningi ekukhiqizweni kokuqukethwe, ikakhulukazi ngenxa yokusetshenziswa kwezintambo ze-HDMI.
Kwesinye isikhathi kunokungahambelani phakathi kwamakhompyutha namadivayisi. ngokwesibonelo, phakathi kwe-TV entsha ne-DVD endala. Lokhu kubangela ukuthi ukudlala okuqukethwe kulengiswe.
Kwesinye isikhathi, ikakhulukazi uma okokusebenza kusha, ukuxhumana phakathi kwabo akuphumelelanga, okuveza ubumnyama besikrini. Uma lokhu kwenzeka kudingekile ukushintsha i-oda lokushintsha amadivayisi kaningana.
Akunakwenzeka ukukhiqiza isithombe esifanayo ezikrinini eziningana ngasikhathi sinye, ngaphandle kokuthi kufakwe inkinobho ye-HDMI ukugwema ukungahambelani kwedivayisi yokufaka isithombe nezinhlelo zokukhipha.
Ngakolunye uhlangothi, lobu buchwepheshe kulula ukubuqonda. Lokho wukuthi, ikhodi yokukhiya oyisebenzisa njengokuvikela isengozini.
Ngenxa yalokhu kuba sengozini, kungenzeka ukugoqa noma iyiphi idivayisi ngokwazi ukhiye wayo osesidlangalaleni. Ngaphezu kwalokho, amaphasiwedi angachithwa futhi ubunikazi bungaphazanyiswa.
