Ilayisensi ye-HDCP ivikela amabhayisikobho aphezulu, amashayimu we-TV nomsindo
Ingabe usanda kuthenga isidlali se- Blu-ray futhi uzibuze ukuthi kungani ngeke ukudlala? Ingabe usebenzisa i- HDMI , i-DVI noma i-DP amakhodi futhi uthole iphutha lezinye izikhathi uma uzama ukubonisa okuqukethwe kwevidiyo? Ngesikhathi sokuthenga i-TV entsha, ingabe wazibuza ukuthi i-HDCP isho ukuthini?
Uma enye yalezi zimo ichaza isimo sakho, kungenzeka ukuthi unenkinga yokuhambisana ne-HDCP.
Kuyini i-HDCP?
Ukuvikelwa kokuqukethwe okuphezulu kwe-bandwidth (HDCP) kuyisici sokuphepha esakhiwe yi-Intel Corporation esidinga ukusetshenziswa kwemikhiqizo eqinisekisiwe ye-HDCP ukuthola isignali ye-digital encrypted nge-HDCP.
Isebenza ngokubethela isignali yedijithali ngesikhiye esidinga ukuqinisekiswa kusuka kokubili imikhiqizo yokudlulisa nokuthola. Uma ukuqinisekiswa kwehluleka, isignali yehluleka.
Inhloso ye-HDCP
I-Digital Content Protection LLC, insizakalo encane ye-Intel elayisensi ye-HDCP, ichaza injongo yayo njengama-technologies welayisense ukuvikela ama-movie adijithali aphezulu, imibukiso ye-TV nomsindo ovela ekufinyeleleni okungagunyaziwe noma ukukopisha.
Inguqulo ye-HDCP yamanje kakhulu engu-2.3, eyakhishwa ngo-February 2018. Imikhiqizo eminingi emakethe ine-HDCP yangaphambilini, okuhle ngoba i-HDCP iyahambisana nezinguqulo zonke.
Okuqukethwe kwe-Digital nge-HDCP
I-Sony Pictures Entertainment Inc., I-Walt Disney Inkampani, ne-Warner Bros. kwakungu-adopters zakuqala ze-HDCP yokubethela ubuchwepheshe.
Kunzima ukukhomba ukuthi yikuphi okuqukethwe okunokuvikelwa kwe-HDCP, kodwa ngokuqinisekile kungabhaliswa nganoma yiluphi uhlobo lwe- Blu-ray disc, i-DVD yokuqasha, ikhebula noma isevisi yesathelayithi, noma uhlelo lokukhokha ngalinye.
I-DCP ivumele amala amakhulu wabakhiqizi njengezamukeli ze-HDCP.
Ixhuma i-HDCP
I-HDCP iyasebenza uma usebenzisa i-digital HDMI noma i-DVI cable. Uma yonke imikhiqizo esebenzisa lezi zicucu ine-HDCP, akufanele uqaphele lutho. I-HDCP yakhelwe ukuvimbela ukweba kokuqukethwe kwedijithali, okuyinto enye yokusho ukurekhoda. Ngenxa yalokho, kukhona ukulinganiselwa ukuthi zingaki izingxenye ongazixhuma.
Indlela i-HDCP ethinta ngayo abathengi
Inkinga eseduze ukulethwa kwesignali yedijithali ngokusebenzisa ikhebula ledijithali kudivayisi yokubukwa kwedijithali, njenge-Blu-ray player player ukuthumela isithombe esingu-1080p ku-1080p HDTV ngekhebula le-HDMI.
Uma yonke imikhiqizo esetshenziselwa i-HDCP-isiqinisekisiwe, umthengi ngeke abone lutho. Inkinga kwenzeka uma omunye wemikhiqizo engeyona i-HDCP-eqinisekisiwe. Isici esiyinhloko se-HDCP ukuthi akudingeki umthetho ukuba uhambisane nazo zonke izikhonkwane. Kuyinto ubuhlobo bokulayisenisa ngokuzithandela phakathi kwe-DCP nezinkampani ezihlukahlukene.
Noma kunjalo, ukushaqeka okungalindelekile kumthengi oxhuma isidlali se-Blu-ray disc kwi-HDTV enekhebula le-HDMI ngaphandle kokubona isignali. Isixazululo salesi simo ukuthi sisebenzise izintambo zomkhakha esikhundleni se-HDMI noma ukufaka esikhundleni se-TV. Akusibo isivumelwano abathengi abaningi abacabanga ukuthi bavumelane lapho bethenga i-HDTV engeyona i-HDCP elayisenyiwe.
Imikhiqizo ye-HDCP
Imikhiqizo ene-HDCP ihlelwa emithonjeni emithathu yamithombo, ama-sink, nama-repeaters:
- Imithombo yikhiqizo lapho isignali ye-HDCP ivela khona. Ziyi-A iphuzu ku-oda A-to-B-to-C yemicimbi. Imikhiqizo yalesi sigaba ihlanganisa ama-DVR, amabhokisi asethethiwe, ama-digital tuners, abadlali be-Blu-ray, namarekhodi e-DVD.
- Ukucwenga yimikhiqizo ethola isignali ye-HDCP futhi ibonise endaweni ethile. Ziyi-C iphuzu ku-oda ye-A-to-B-to-C yemicimbi. Imikhiqizo yalesi sigaba ihlanganisa ama-TV namaphrojekitha wedijithali.
- Ukuphinda kubhekwe yimikhiqizo ethola isignali ye-HDCP kusuka emthonjeni bese uyithumela kudoti. Ziyi-B iphuzu lokuhlelwa kwemicimbi ye-A-to-B-to-C. Imikhiqizo yalesi sigaba ihlanganisa abaphindaphindiwe, abahlukanisi, ama-switchers, abamukeli be-AV, nabathumeli abangenazintambo.
Kumthengi ofuna ukwazi ukuthi umkhiqizo une-HDCP, i-DCP ishicilela uhlu lwemikhiqizo evunyelwe kuwebhusayithi yayo.
