I-HDMI interface kanye nokucaciswa

Imiqondo ehilelekile yilena:

I-TMDS: (Isiginali Eyenziwe Ngesiginali Encishisiwe) Ukudluliswa kwesignali ehlukanisiwe okuncishisiwe, kuyindlela yokudlulisa isignali ehlukile, isiteshi sokudlulisa isignali ye-HDMI samukelwe ngale ndlela.

I-HDCP: (I-High-bandwidthDigital Content Protection) Ukuvikelwa kokuqukethwe kwedijithali komkhawulokudonsa ophezulu.

I-DDC: Bonisa Isiteshi Sedatha

CEC: Consumer Electronics Control

I-EDID: Idatha Yokuhlonza Isibonisi Enwetshiwe

I-E-EDIO: Idatha Yokuhlonza Enwetshiwe Ethuthukisiwe

Ukumelwa kwabo enqubweni yokudlulisela ye-HDMI cishe kungokulandelayo:

Ukuthuthukiswa kwenguqulo ye-HDMI

I-HDMI 1.0

Inguqulo ye-HDMI 1.0 yethulwa ngoZibandlela wezi-2002, isici sayo esikhulu ukuhlanganisa isixhumi esibonakalayo sedijithali sokusakazwa komsindo, bese isixhumi esibonakalayo se-PC sithandwa kakhulu ku-DVI interface uma siqhathaniswa, sithuthuke kakhulu futhi sivumelana kakhulu.

Inguqulo ye-HDMI engu-1.0 isekela ukusakazwa kwevidiyo kusuka ku-DVD kuya kufomethi ye-Blu-ray, futhi inomsebenzi we-CEC (ukulawula ugesi wabathengi), okungukuthi, kuhlelo lokusebenza, ungakha isixhumanisi esivamile phakathi kwawo wonke amadivaysi axhunyiwe, iqembu ledivayisi linokulawula okulula kakhulu.

I-HDMI 1.1

Ingxoxo ye-HDMI inguqulo 1.1 ngoMeyi 2004. Usekelo olungeziwe lomsindo we-DVD.

I-HDMI 1.2

Inguqulo ye-HDMI 1.2 yethulwa ngo-Agasti 2005, ngezinga elikhulu ukuxazulula ukuxazululwa kokusekelwa kwe-HDMI 1.1 iphansi, nezinkinga zokuhambisana nemishini yekhompyutha. Inguqulo engu-1.2 yewashi le-pixel isebenza ku-165 MHz futhi ivolumu yedatha ifinyelela ku-4.95 Gbps, ngakho-ke 1080 P. Kungacatshangwa ukuthi inguqulo 1.2 ixazulula inkinga ye-TV engu-1080P kanye nenkinga yephoyinti nephoyinti yekhompyutha.

I-HDMI 1.3

NgoJuni 2006, isibuyekezo se-HDMI 1.3 silethe ushintsho olukhulu kakhulu kumvamisa yomkhawulokudonsa wesixhumanisi esisodwa ukuya ku-340 MHz. Lokhu kuzokwenza lawa ma-TV e-LCD akwazi ukuthola ukudluliswa kwedatha okungu-10.2Gbps, futhi inguqulo engu-1.3 yolayini yakhiwe ngamapheya amane eziteshi zokudlulisela, lapho ipheya elilodwa lamashaneli kuyisiteshi sewashi, kanti amanye amapheya amathathu amashaneli e-TMDS (ukunciphisa ukudluliswa kwezimpawu ezihlukile), isivinini sabo sokudlulisa singama-3.4GBPs. Khona-ke amapheya angu-3 ngu-3 * 3.4 = 10.2 GPBS ikwazi ukwandisa kakhulu ukujula kombala we-24-bit okusekelwa i-HDMI1.1 nezinguqulo ezingu-1.2 kuya ku-30, 36 kanye namabhithi angu-48 (RGB noma YCbCr). I-HDMI 1.3 isekela i-1080 P; Enye ye-3D engafuneki kangako nayo iyasekelwa (ngokweqile ayisekelwe, kodwa empeleni eminye ingasekelwa).

I-HDMI 1.4

Inguqulo ye-HDMI 1.4 isingakwazi kakade ukusekela i-4K, kodwa ingaphansi komkhawulokudonsa ongu-10.2Gbps, umkhawulo ungafinyelela kuphela ukulungiswa kwe-3840 × 2160 kanye nesilinganiso sozimele esingu-30FPS.

I-HDMI 2.0

I-bandwidth ye-HDMI 2.0 inwetshwe ku-18Gbps, isekela ukuxhuma okulungele ukusetshenziswa nokushisayo, isekela ukulungiswa kwe-3840 × 2160 kanye ne-50FPS, izilinganiso zozimele ze-60FPS. Ngesikhathi esifanayo ekusekelweni komsindo kufika eziteshini ezingu-32, kanye nesilinganiso esiphezulu samasampula esingu-1536 kHz. I-HDMI 2.0 ayichazi imigqa emisha yedijithali nezixhumi, izixhumanisi, ngakho-ke ingakwazi ukugcina ukuhambisana okuphelele emuva ne-HDMI 1.x, futhi izinhlobo ezimbili ezikhona zemigqa yedijithali zingasetshenziswa ngokuqondile. I-HDMI 2.0 ngeke ingene esikhundleni se-HDMI 1.x, kodwa ngokusekelwe ekuthuthukisweni kwakamuva, noma iyiphi idivayisi esekela i-HDMI 2.0 kufanele iqale iqinisekise ukusekela okuyisisekelo kwe-HDMI 1.x.

I-HDMI 2.1

Izinga lihlinzeka ngomkhawulokudonsa ongafika ku-48Gbps, futhi ikakhulukazi, izinga elisha le-HDMI 2.1 manje selisekela i-7680 × 4320 @ 60Hz kanye ne-4K @ 120hz. I-4 K ihlanganisa amaphikseli angu-4096 × 2160 namaphikiseli angu-3840 × 2160 we-4 K yangempela, kuyilapho ekucacisweni kwe-HDMI 2.0, kusekelwa i-4 K @ 60Hz kuphela.

Uhlobo lwesixhumi esibonakalayo se-HDMI:

Uhlobo A lwe-HDMI A ikhebuli esetshenziswa kakhulu ye-HDMI enamaphini angu-19, ububanzi obungu-13.9 mm nogqinsi obungu-4.45 mm. I-TV yesikrini esiyisicaba esivamile noma okokusebenza kwevidiyo, kuhlinzekwa ngalo sayizi wesixhumi esibonakalayo, Uhlobo A lunamaphini angu-19, ububanzi bungu-13.9 mm, ukujiya bungu-4.45 mm, futhi manje u-99% wezinto ezilalelwayo nevidiyo ezisetshenziswa ekuphileni kwansuku zonke zifakelwe lo sayizi wesixhumi esibonakalayo. Isibonelo: Isidlali se-Blu-ray, ibhokisi le-millet, ikhompyutha ye-notebook, i-LCD TV, i-projektha nokunye.

Uhlobo B lwe-HDMI B Uhlobo luyivelakancane empilweni. Isixhumi se-HDMI B sinamaphinikhodi angu-29 nobubanzi obungu-21 mm. Amandla okudlulisa idatha oHlobo lwe-HDMI acishe abe kabili ngokushesha kunohlobo lwe-HDMI A futhi alingana ne-DVI Dual-Link. Njengoba imishini eminingi yomsindo nevidiyo isebenza ngaphansi kuka-165MHz, futhi imvamisa yokusebenza yohlobo lwe-HDMI B ingaphezulu kuka-270MHz, "inzima" ngokuphelele ezinhlelweni zasekhaya, futhi manje isisetshenziswa kuphela ezikhathini ezithile zobungcweti, njenge-WQXGA 2560 × 1600 resolution. .

Uhlobo C lwe-HDMI C, oluvame ukubizwa nge-Mini HDMI, luklanyelwe kakhulu amadivaysi amancane. Uhlobo lwe-HDMI C luphinde lusebenzise iphinikhodi engu-19, ubukhulu bayo obungu-10.42 × 2.4 mm bucishe bube yi-1/3 encane kunoHlobo A, uhla lohlelo lokusebenza luncane kakhulu, lusetshenziswa kakhulu kumadivayisi aphathwayo, njengamakhamera edijithali, izidlali eziphathwayo nezinye izinto zokusebenza.

Uhlobo D lwe-HDMI D lujwayele ukubizwa ngokuthi i-Micro HDMI. Uhlobo lwe-HDMI D wuhlobo lwakamuva lokusebenzelana, oluncishiswe ngokwengeziwe ngosayizi. Idizayini yephinikhodi enemigqa emibili, namaphinikhodi angu-19, inobubanzi obungu-6.4 mm kuphela nobukhulu obungu-2.8 mm, ifana ne-Mini USB interface. Isetshenziswa kakhulu kumadivaysi eselula amancane, afaneleka kakhulu izinto eziphathwayo nezemoto. Isibonelo: omakhalekhukhwini, amaphilisi, njll.

Uhlobo E (Uhlobo E) Uhlobo lwe-HDMI E lusetshenziswa kakhulu ekudluliseni umsindo nevidiyo kumasistimu okuzijabulisa asemotweni. Ngenxa yokungaqini kahle kwendawo yangaphakathi yemoto, Uhlobo lwe-HDMI E luklanyelwe ukuba lube nezici ezinjengokumelana nokuzamazama komhlaba, ukumelana nomswakama, ukumelana namandla aphezulu, nokubekezelela umehluko omkhulu wokushisa. Esakhiweni somzimba, umklamo wokukhiya ngomshini ungaqinisekisa ukwethembeka kokuxhumana.
