Isivinini esikhulu nekhophi evikelwe idijithali
Thenga i-HDTV ehambisana ne-HDCP noma ngabe ulungele ukubambisana noDeveli uma usebenzisa izintambo ze-HDMI noma ze-DVI.
Isizathu sokuthi ngibhekisela ku-HDCP njengoDeveli ngoba i-HDCP kungenzeka ukuthi ingenye yezobuchwepheshe obubucayi kakhulu ngoba itholakala e-altare lokulawula indlela esibukela ngayo izinhlelo ze-digital. Ngenkathi inhloso ye-HDCP ihloniphekile - ukuvikela ukwaziswa okune-copyright - ukuphazanyiswa okubangela ukuba abalindi be-TV abagcina umthetho baqakathekile kakhulu ukungayinaki.
Iyini i-HDCP?
I-HDCP imelela ukuvikelwa kokuqukethwe okuphezulu kwe-Bandwidth futhi ithuthukiswe yi-Intel Corporation. Akuyona into engaphezu kwesici sokuphepha esidinga ukuhambisana phakathi komthumeli nomamukeli, njengebhodi le-HD set-top box ne-TV. Ngokuhambisana, ngisho ubuchwepheshe be-HDCP ekwakhiwe kuwo wonke amadivayisi.
Cabanga nge-HDCP njengenkinobho yelayisensi yokuphepha njengoba uzofaka uma ufaka uhlelo lwekhompyutha. Kuphela kuphela ukhiye wokuphepha ongabonakali wena nami kodwa hhayi iTV yakho.
Isebenza ngokubethela isignali yedijithali ngesikhiye esidinga ukuqinisekiswa kusukela ekudluliseni nasekutholeni umkhiqizo. Uma ukuqinisekiswa kwehluleka khona, isignali yehluleka, okusho ukuthi akukho sithombe esikrinini se-TV.
Ungase uzibuze, "Ubani ofuna isignali ye-TV ihluleke? Akuyona iphuzu ithelevishini ukujabulela ukubukela?"
Ungacabanga ngakho kodwa i-HDCP imayelana nemali. Inkinga yukuthi ubuchwepheshe bedijithali benza ukuthi ukuphikisana kokuqukethwe kube lula. Khumbula i Napster? Ingabe uke uzwe ngezingqikithi zamavidiyo ezithengisa ama-movie ngaphandle kwezingubo zawo? Lona iphuzu le-HDCP - akukho ukukhiqizwa okungemthetho.
Lokhu mayelana nama-copyrights. Ngokuphathelene nokuthengisa okuqukethwe kunokuba uyinike. Akuyona imfihlo ukuthi imboni yezithombe ezithinta izithombe zamukela i-HDCP ngokusebenzisa ama-Blu-ray disks ngenkathi imboni ye-TV ingakabandakanyeki ngalesi sikhathi. Kuyavunywa, imboni ye-TV inesabelo sayo siqu ngokuqaliswa kwe-TV ye-digital.
Uphi i-HDCP?
Kubalulekile ukuthi uqonde ukuthi i-HDCP iyinhlangano yobuchwepheshe bedijithali. Ngenxa yalokho, isebenza kuphela njengamanje ngamakhodi e-DVI ne-HDMI. Ngakho-ke ama-DVI / HDCP ne-HDMI / HDCP ama-acronyms.
Kuyini i-DVI?
I-DVI idalwe yi-Digital Display Working Group, futhi imele i-Digital Visual Interface. Kuyinto isikhombimsebenzisi esibonakalayo esidala se-digital esinezinto eziningi kodwa sithathwe esikhundleni se-HDMI kumathelevishini ngakho ngeke ngichithe isikhathi esiningi ku-DVI / HDCP. Yazi nje ukuthi uma une-HDTV ene-DVI input, i-HDCP ingaba yinkinga ngesinye isikhathi uma ingakafiki.
Iyini i-HDMI?
I-HDMI imele isikhulumi se-High-Definition Multimedia. Kuyinto isikhombimsebenzisi esibonakalayo ukuthi uzoyisebenzisa nge-HDTV yakho ukuze uthole isithombe esingcono kakhulu, esingenakunyakaziswa kwedijithali. I-HDMI inokusekelwa okukhulu kusukela embonini yesithombe sokunyakaza. Yadalwa ezinye zezinto ezisindayo embonini yomthengi kagesi - Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, noToshiba.
Kunezinzuzo ezimbili ezibalulekile ze-HDMI ngaphezu kwe-DVI:
- I-HDMI ithumela isignali yomsindo nevidiyo kwelinye ikhebula. I-DVI idlulisa kuphela ividiyo ukuze ikhebula elilalelwayo elihlukile liyadingeka.
- I-HDMI ihamba ngokushesha kakhulu kune-DVI, okusho ukuthi ulwazi oluningi luhanjiswe kusikrini sakho se-TV.
Umhlahlandlela we-About.com we-Home Theater, uRobert Silva, unesihloko esihle kakhulu esichaza umehluko phakathi kwezinguqulo ze-HDMI .
I-HDCP Ukuthenga Iseluleko
Thenga i-HDTV enekhono le-HDCP. Abaningi bazoba okungenani lokhu okufakwayo kwe-HDMI kodwa baqiniseke ukuqinisekisa lokhu ngaphambi kokuthenga i-TV.
Qaphela ukuthi ngibhale, "okungenani ichweba elilodwa." Akuzona zonke izibuko ze-HDMI ku-TV ezizovumelana ne-HDCP ngakho qiniseka ukuthi ufunde incwadi yakho yomsebenzisi we-TV uma uhlela ukuxhuma ikhebula le-HDMI ku-TV yakho.
Akukho ukuthuthukiswa kwe-firmware okungashintsha ukungena okungenayo i-HDCP ekufakeni okuhambisana ne-HDCP. Uma uthenge i-HDTV eminyakeni embalwa eyedlule-ke kukhona ithuba elikhulu lokuthi uzothola iphutha le- HDCP uma uxhuma isidlali se-Blu-ray Disc ku-HDTV yakho nge-HDMI. Lokhu kuzokuphoqelela ukuba usebenzise ikhebula elingenayo idijithali, ukuthenga i-HDTV entsha noma ukukhipha isidlali se-Blu-ray Disc.
