Ilayisensi ye-HDCP ikhusela i-movie-value value, imiboniso yeTV kunye nesandi
Ngaba usanda kuthenga umdlali we- Blu-ray Disc kwaye uzibuza ukuba kutheni? Ngaba usebenzisa ii- HDMI , DVI okanye iDP kunye neefayile ezithile xa uzama ukubonisa umxholo wevidiyo? Kwinkqubo yokuthenga i-TV entsha, ngaba uyazibuza ukuba i-HDCP yayithetha ukuthini?
Ukuba enye yezi ziganeko zichaza imeko yakho, mhlawumbi unomcimbi wokuhambelana ne-HDCP.
Yintoni i-HDCP?
I-High-bandwidth Digital Content Protection (HDCP) yinto ekhuselekileyo eyenziwa yi-Intel Corporation efuna ukusetyenziswa kweemveliso eziqinisekisiweyo ze-HDCP ukufumana isigxina se-DSC-encrypted signal.
Isebenza ngokubetha isignali yedijithali ngenqakraza efuna ukuqinisekiswa kwizinto zombini ezithumelayo nezifumanayo. Ukuba ukuqinisekiswa kwehluleka, uphawu aluphumelelanga.
Injongo ye-HDCP
I-Digital Content Protection LLC, inkonzo engumncedisi ye-Intel ephethe ilayisenisi ye-HDCP, ichaza injongo yayo njengeteknoloji yeelayisenisi ukukhusela i-movie-digital value yamabonakude, imiboniso yeTV kunye ne-audio ekufikeleleni okungagunyazisiweyo okanye ukukopisha.
Ininzi ye-HDCP yangoku ngu-2.3, eyakhishwa ngoFebruwari 2018. ezininzi iimveliso kwiimarike zineenkcukacha zangaphambili ze-HDCP, efanelekileyo ngoba i-HDCP iyahambelana kuzo zonke iinguqulelo.
Idijithali yokudibanisa ne-HDCP
I-Sony Pictures Entertainment Inc., i-Walt Disney Inkampani, kunye neWarner Bros babemele baqalise ubuchwepheshe be-encryption ye-HDCP.
Kunzima ukuphawula ukuba yintoni umxholo onokukhuselwa kwe-HDCP, kodwa ngokuqinisekileyo inokubethelwa kukho nawuphi na uhlobo lwe- Blu-ray disc, i-DVD yokuqashisa, i-cable okanye isevisi ye-satellite, okanye inkqubo yokuhlawula nganye.
ICandelo le-DCP livumele ikhulu lemveliso yabavelisi njenge-HDCP.
Ukuxhuma i-HDCP
I-HDCP ifanelekileyo xa usebenzisa i-digital HDMI okanye i-DVI. Ukuba yonke imveliso esebenzisa ezi ngcingo i-HDCP, ngoko akufanele uqaphele nto. I-HDCP yenzelwe ukuthintela ukweba komxholo wedijithali, enye enye indlela yokuthetha ukurekhoda. Ngenxa yoko, kukho ukulinganiselwa ukuba zingaphi izixhobo onokuzidibanisa ngazo.
Indlela i-HDCP ithinta ngayo umThengi
Umcimbi okhoyo ukuhanjiswa kwesiginari sejithali ngokusebenzisa ikhebula ledijithali kwidivaysi yokubukela idijithali, njengomdlali we-Blu-ray disc ukuthumela umfanekiso we-1080p kwi-1080p HDTV ngekhebula le-HDMI.
Ukuba zonke iimveliso ezisetyenziselwa i-HDCP-eziqinisekisiweyo, umboleki akayi kubona nayiphi na into. Ingxaki iyenzeka xa enye yeemveliso ayiyi-certified HDCP. Inkalo ebalulekileyo ye-HDCP kukuba akufunwa ngumthetho ukuba ihambelane nayo yonke inxibelelwano. Ulwalamano lokuzithandela ngokuzithandela phakathi kwe-DCP kunye neenkampani ezahlukeneyo.
Sekunjalo, ukutshitshiswa okungalindelekanga kumthengi odibanisa umdlali we-Blu-ray disc kwi-HDTV enekhebula le-HDMI kuphela ukuba angaboni uphawu. Isisombululo kule meko kukusebenzisa iicandelo zecandelo esikhundleni se-HDMI okanye ukubuyisela iTV. Leyo ayikho isivumelwano abaninzi abathengi bacinga ukuba bavumelana xa bethenge i-HDTV engekho i-HDCP ilayisenisi.
Imveliso yeHDCP
Iimveliso nge-HDCP zihlanjululwa zibe yimithombo emithathu yamabhakethi, i-sinks, kunye nabaphindi:
- Imithombo yile mveliso apho uphawu lwe-HDCP luvela khona. ZiyiNgongoma ye-A-to-B-to-C yeemeko. Imveliso kule ndawo iquka i-DVRs, iibhokisi ze-set-top, i-digital tuners, abadlali be-Blu-ray kunye ne-DVD.
- Iitshini ziyimveliso efumana isignali ye-HDCP kwaye ibonise kwindawo ethile. Ziyiyona nkalo yeC in order ye-A-to-B-to-C yeemeko. Imveliso kule candelo iquka iiTV kunye nabaprojekthi zedijithali.
- Abaphinda baphinda baphinda bafumana i-HDCP uphawu ukusuka kumthombo kwaye bayithumela kwisitya. Ziyiyona ngongoma B kwi-A-to-B-to-C yeemeko. Imveliso kule ndawo ibandakanya abaphinda baphinda, abahlukanisi, abaguquleli, abalamkeli be-AV kunye nabathumeli abangenazintambo.
Umthengi onomdla ofuna ukuqinisekisa ukuba imveliso ine HDCP, i-DCP ipapasha uluhlu lweemveliso ezivunyiweyo kwiwebhusayithi yayo.
