Ujongano lweHDMI kunye neenkcukacha

Iikhonsepthi ezibandakanyekayo zezi:

I-TMDS: (Ixesha eliNcitshisiweyo eliNcincisiweyo loMbonakaliso) Ukuhanjiswa kweempawu ezincitshisiweyo ezincitshisiweyo, yindlela yokuhanjiswa kweempawu ezahlukileyo, i-HDMI ishaneli yokuhambisa isignali esamkelwe ngale ndlela.

I-HDCP: (I-High-bandwidthDigital Content Protection) Ukhuseleko lomxholo wedijithali ophakamileyo.

I-DDC: Bonisa iSiteshi seDatha

I-CEC: Ulawulo lwe-Electronics yabathengi

I-EDID: IDatha yeSaziso eYandisiweyo

I-E-EDIO: Ukwandiswa kweDatha yeSaziso sokuBonisa eYandisiweyo

Ukumelwa kwabo kwinkqubo yokuhanjiswa kwe-HDMI malunga noku kulandelayo:

Uphuhliso lwenguqulelo yeHDMI

I-HDMI 1.0

I-HDMI inguqulo ye-1.0 yaziswa ngoDisemba ka-2002, eyona nto ibaluleke kakhulu kukudityaniswa kwe-audio stream interface yedijithali, kwaye ke i-interface ye-PC ithandwa kakhulu kwi-interface ye-DVI xa kuthelekiswa, iphambili kwaye ilungele ngakumbi.

I-HDMI inguqulo ye-1.0 isekela ukuhanjiswa kwevidiyo ukusuka kwi-DVD ukuya kwifomathi ye-Blu-ray, kwaye inomsebenzi we-CEC (ulawulo lwe-elektroniki yabathengi), oko kukuthi, kwisicelo, unokwenza ikhonkco eliqhelekileyo phakathi kwazo zonke izixhobo ezixhunyiwe, iqela lesixhobo linolawulo olulula ngakumbi.

I-HDMI 1.1

Udliwano-ndlebe lweHDMI inguqulo 1.1 ngoMeyi 2004. Inkxaso eyongeziweyo yomsindo weDVD.

I-HDMI 1.2

I-HDMI inguqulo ye-1.2 yasungulwa ngo-Agasti 2005, kwinqanaba elikhulu lokusombulula isisombululo se-HDMI 1.1 inkxaso iphantsi, kunye neengxaki zokuhambelana nezixhobo zekhompyutha. Inguqulo ye-1.2 yewashi ye-pixel isebenza kwi-165 MHz kwaye umthamo wedatha ufikelela kwi-4.95 Gbps, ngoko ke i-1080 P. Inokuthi ithathelwe ingqalelo ukuba i-version 1.2 isombulula ingxaki ye-TV ye-1080P kunye nengxaki ye-point-to-point yekhompyutheni.

I-HDMI 1.3

NgoJuni 2006, uhlaziyo lwe-HDMI 1.3 luzisa utshintsho olukhulu kwi-single-link bandwidth frequency kwi-340 MHz. Oku kuya kwenza ukuba ezi LCD TV zikwazi ukufumana i-10.2Gbps yosasazo lwedatha, kwaye inguqulelo ye-1.3 yomgca iqulunqwe ngamaqela amane othungelwano lwejelo, apho elinye itshaneli yitshaneli yewotshi, kwaye ezinye izibini ezintathu ngamajelo e-TMDS (ukunciphisa. ukuhanjiswa kweempawu ezahlukeneyo), isantya sabo sokuhambisa si-3.4GBPs. Emva koko i-3 pairs yi-3 * 3.4 = 10.2 GPBS iyakwazi ukwandisa kakhulu ubunzulu bombala we-24-bit exhaswa yi-HDMI1.1 kunye ne-1.2 iinguqulelo kwi-30, i-36 kunye ne-48 bits (RGB okanye i-YCbCr). I-HDMI 1.3 ixhasa i-1080 P; Enye ye-3D engabalulekanga kangako nayo iyaxhaswa (ithiyori ayixhaswanga, kodwa eneneni abanye banako).

I-HDMI 1.4

I-HDMI inguqulo ye-1.4 ingaba sele ixhasa i-4K, kodwa ixhomekeke kwi-bandwidth ye-10.2Gbps, ubuninzi bunokufikelela kuphela kwi-3840 × 2160 isisombululo kunye ne-30FPS yefreyimu yesantya.

I-HDMI 2.0

I-bandwidth ye-HDMI 2.0 yandiswe kwi-18Gbps, isekela i-plugging ekulungele ukusetyenziswa kunye neshushu, ixhasa isisombululo se-3840 × 2160 kunye ne-50FPS, i-60FPS imilinganiselo yefreyimu. Ngexesha elifanayo kwinkxaso yomsindo ukuya kumatshaneli angama-32, kunye nesantya esiphezulu sesampuli ye-1536 kHz. I-HDMI 2.0 ayichazi imigca emitsha yedijithali kunye neziqhagamshelo, i-interfaces, ngoko inokugcina ukuhambelana okugqibeleleyo ngasemva kunye ne-HDMI 1.x, kunye neentlobo ezimbini ezikhoyo zemigca yedijithali zingasetyenziswa ngokuthe ngqo. I-HDMI 2.0 ayiyi kuthatha indawo ye-HDMI 1.x, kodwa ngokusekelwe ekuphuculeni kokugqibela, nasiphi na isixhobo sokuxhasa i-HDMI 2.0 kufuneka siqale siqinisekise inkxaso eyisiseko ye-HDMI 1.x.

I-HDMI 2.1

Umgangatho ubonelela nge-bandwidth ukuya kwi-48Gbps, kwaye ngakumbi ngakumbi, umgangatho omtsha we-HDMI 2.1 ngoku uxhasa i-7680 × 4320 @ 60Hz kunye ne-4K @ 120hz. I-4 K ibandakanya i-4096 × 2160 pixels kunye ne-3840 × 2160 pixels ye-4 K yenyani, ngelixa kwi-HDMI inkcazo ye-2.0, kuphela i-4 K @ 60Hz ixhaswa.

Uhlobo lweNdibaniselwano yeHDMI:

Uhlobo A lwe-HDMI A Uhlobo lolona lusetyenziswa kakhulu intambo ye-HDMI enezikhonkwane eziyi-19, ububanzi be-13.9 mm kunye ne-4.45 mm ubukhulu. I-TV ye-flat screen ngokubanzi okanye izixhobo zevidiyo, zibonelelwa ngolu hlobo lwe-interface, Uhlobo lwe-A lunezikhonkwane ze-19, ububanzi be-13.9 mm, ubukhulu be-4.45 mm, kwaye ngoku i-99% yezixhobo zomsindo kunye nevidiyo ezisetyenziswa kubomi bemihla ngemihla zixhotyiswe obu bungakanani bojongano. Umzekelo: Umdlali we-Blu-ray, ibhokisi ye-millet, ikhompyutha ye-notebook, i-LCD TV, iprojekti njalo njalo.

Uhlobo B lweHDMI B Uhlobo lunqabile ebomini. Isixhumi se-HDMI B sinezikhonkwane ezingama-29 kunye ne-21 mm ububanzi. I-HDMI B Uhlobo lokudlulisa idatha luphantse lube kabini ngokukhawuleza njenge-HDMI A Uhlobo kwaye lulingana ne-DVI Dual-Link. Ekubeni izixhobo ezininzi zeaudio kunye nevidiyo zisebenza ngaphantsi kwe-165MHz, kunye nokusebenza rhoqo kwe-HDMI B Uhlobo lungaphezulu kwe-270MHz, "inzima" ngokupheleleyo kwizicelo zasekhaya, kwaye ngoku isetyenziswa kuphela kwiimeko ezithile zobungcali, njenge-WQXGA 2560 × 1600 isisombululo. .

Uhlobo C lwe-HDMI C Uhlobo, oluhlala lubizwa ngokuba yi-Mini HDMI, luyilelwe ikakhulu izixhobo ezincinci. I-HDMI C Uhlobo luphinde lusebenzise i-pin ye-19, ubukhulu bayo be-10.42 × 2.4 mm buphantse bube yi-1/3 encinci kune-Type A, uluhlu lwesicelo luncinci kakhulu, lusetyenziswa kakhulu kwizixhobo eziphathekayo, ezifana neekhamera zedijithali, abadlali abaphathwayo kunye nezinye izixhobo.

Uhlobo lwe-D HDMI D luyaziwa ngokuba yi-Micro HDMI. Uhlobo lwe-HDMI D luhlobo lwamva nje lojongano, oluncitshiswe ngakumbi ngobukhulu. Uyilo lwephini elinemiqolo emibini, kunye nezikhonkwane ezili-19, bububanzi obuyi-6.4 mm kuphela kunye ne-2.8 mm ubukhulu, bufana ne-Mini USB interface. Ikakhulu isetyenziswa kwizixhobo ezincinci eziphathwayo, ezifanelekileyo ngakumbi kwisixhobo esiphathwayo kunye nesithuthi. Umzekelo: iifowuni eziphathwayo, iipilisi, njl.

Uhlobo E (Uhlobo E) Uhlobo lwe-HDMI E lusetyenziselwa ikakhulu ukuhanjiswa kweaudio kunye nevidiyo kwiinkqubo zokuzonwabisa kwimoto. Ngenxa yokungazinzi kwendawo yangaphakathi yesithuthi, Uhlobo lwe-HDMI E lwenzelwe ukuba lube neempawu ezifana nokuchasana kwe-seismic, ukunyanzeliswa komswakama, ukuxhathisa amandla aphezulu, kunye nokunyamezela okukhulu kokushisa. Kwisakhiwo somzimba, uyilo lokutshixa lomatshini unokuqinisekisa ukuthembeka koqhagamshelwano.
