Ukuhanjiswa kwamehlo
Ukususela kwi-2000, kunye nophuhliso lobuchwepheshe bonxibelelwano, unxibelelwano lwefiber optical luvele iteknoloji yokudlulisa imodyuli ye-optical, kwaye emva kwe-2002, ukuhanjiswa kwedijithali Imveliso ye-HDMI yomsindo kunye nevidiyo ibonakala kwintsimi ye-electronics yabathengi. Ngo-Aprili 2002, i-Hitachi, i-Panasonic, i-Philips, i-Silicon Image, i-Sony, i-Thomson, i-Toshiba iinkampani ezisixhenxe ziseke ngokudibeneyo i-HDMI i-high-definition interface ye-interface ye-multimedia, ukuhanjiswa kwe-HDMI kwahlula kwi-speed-speed signal transmission kunye ne-speed-speed signal transmission two parts. : I-1-12 iinyawo ze-12 4 izibini zeentambo zihambisa izibonakaliso zesantya esiphezulu, zisebenzisa i-TMDS iteknoloji yokubonisa umahluko (TMDS (Ixesha elincitshisiweyo) eliqanjwe nguSilicon Image Differential Signal) linciphisa iteknoloji yokudlulisa umbane we-transmission, i-TMDS yindlela yesignali yokwahlukana, usebenzisa imo yokudlulisa ukwahlukana, eyona mgaqo-siseko we-HDMI iteknoloji, kwi-fiber optical transmission HDMI: ezi zimbini ze-4 ze-12 Iintambo ze-TMDS zihanjiswa yi-4 VCSEL + 4 i-multimode optical fibers, enokusombulula ngokulula ingxaki yesantya esiphezulu. usulelo.
Kwi-HDMI i-channel ye-speed-speed transmission channel, i-13-19 izikhonkwane kwi-HDMI zineentambo ze-elektroniki ze-7: umbane we-5V, i-HPD yokutshintsha i-hot-swap isebenze i-CEC, i-intanethi, i-SDA, i-SCA, iziteshi ze-DDC. Isisombululo esibalulekileyo somboniso sifunda ishaneli ye-DDC: ngumyalelo we-interface ye-I2C kwi-HDMI umthombo wokufunda i-E-EDID ekupheleni kokufumana. I-I2C, imfutshane kwi-Integrated Circuit Bus, yibhasi yonxibelelwano lwe-serial esebenzisa i-multi-master-slave architecture. Umqalisi we-I2C ungomnye wabasunguli bentlangano ye-HDMI: Philips Semiconductors.
Iintambo ze-HDMI zidla ngokusetyenziselwa ukudibanisa izixhobo ze-audiovisual kwi-TV kunye nabahloli, ngoko ke uninzi lwazo lugqithiso olufutshane, ngokuqhelekileyo ubude beemitha ezi-3 kuphela; Kufuneka benze ntoni abasebenzisi ukuba bafuna ngaphezu kweemitha ezi-3? Ukuba uqhubeka usebenzisa ucingo lobhedu, ububanzi bocingo lobhedu luya kuba lukhulu, kuya kuba nzima ukugoba, kwaye iindleko ziya kuba phezulu. Ngoko ke, eyona ndlela ilungileyo kukusebenzisa iifiber optical. Imveliso yentambo ye-HDMI ye-HDMI ye-AOC ye-optical hybrid ngokwenene iyimveliso yokuthotyelwa kobugcisa, injongo yasekuqaleni kuphuhliso kufuneka ibe kukuba zonke iintambo ze-HDMI 19 zidlulisa i-fiber optical, eyona nto i-optical fiber transmission ye-HDMI, kodwa ngenxa yokuba iintambo ze-7 ze-low-. Ijelo elikhawulezayo lisebenzisa iVCSEL+ i-multimode ifayibha enesantya esisezantsi sokufakwa kwekhowudi kunye nokuchaza ikhowudi kunzima ngakumbi, ngokulula umphuhlisi kuphela umqondiso wesantya esiphezulu kwizibini ezi-4 ze Iziteshi ze-TMDS ukuya kwi-VCSEL + i-multimode fiber transmission, i-7 eseleyo iingcingo ze-elektroniki zisaxhunywe ngokuthe ngqo ngocingo lobheduKwafunyaniswa ukuba emva kokuba umqondiso we-high-speed uhanjiswe nge-fiber optical, ngenxa yokwandiswa komgama wokuhambisa umqondiso we-TMDS, i-fiber optical HDMI. I-AOC inokudluliselwa kwiimitha ezili-100 okanye nangaphezulu.
Intambo ye-Optical fiber HDMI i-AOC ye-hybrid cable ngenxa yokuba i-speed-speed-speed signal isasebenzisa ukuhanjiswa kocingo lobhedu, ingxaki ye-high-speed signal isonjululwe, kwaye ingxaki ye-low-speed signal ye-copper transmission ayikasonjululwa, ngoko ixhomekeke kwiindlela ezahlukeneyo zokuhambelana. iingxaki kuthumelo lomgama omde. Kwaye konke oku kunokusombululwa ngokupheleleyo ukuba i-HDMI isebenzisa izisombululo zeteknoloji ye-optical. I-HDMI yonke i-optical fibers isebenzisa i-6 optical fibers, i-4 ukuhambisa i-high-speed TMDS izibonakaliso zesiteshi, i-2 ukuhambisa i-HDMI izibonakaliso eziphantsi kwesantya, kunye nokunikezelwa kwamandla angaphandle kwe-5V iyadingeka kwisiphelo sokubonisa i-RX njenge-voltage yokuvuselela i-plugging ye-HPD eshushu. Emva kokwamkela isisombululo se-optical, i-HDMI, i-channel ye-TMDS ephezulu kunye ne-DDC enesantya esisezantsi iguqulwa ibe yi-optical fiber transmission, kwaye umgama wokuhambisa uphuculwe kakhulu.
Inkxaso kwiinkcukacha zeprotocol
Nangona umgca we-hybrid optical copper uye waphakamisa ukuhanjiswa okungalahlekiyo kweempawu ezikude ukuya kwindawo ephakamileyo kakhulu, kusekho iteknoloji exazulula ngokupheleleyo ubukho bocingo lobhedu njengomqhubi wokuhambisa, oko kukuthi, i-fiber optical ecocekileyo HDMI 2.1 umgca, I-HDMI 2.1 intambo ecocekileyo ye-optical optical (AOC) ihambelana ngokupheleleyo ne-HDMI 2.1 standard, ukuhanjiswa kwesignali konke kusebenzisa i-fiber optical, ayinakho ubhedu. ngocingo, ukuhanjiswa kwefiber optical akukho phantsi kokuphazamiseka kombane. Isignali yokuhanjiswa kwe-AOC ayinyanzelwanga, i-bandwidth ephezulu yi-48Gbps, inokuhambisa ngokugqibeleleyo imifanekiso ye-8K ephezulu-high-definition, umgama omde wokuhambisa unokufikelela kwi-500m. Xa kuthelekiswa neengcingo zobhedu zemveli, le ntambo yefiber optic inde, ithambile, ikhaphukhaphu, inomgangatho ongcono wesignali kunye neempawu ezihambelana ne-electromagnetic ehambelanayo. Ekuqaleni konyaka, i-HDMI Umbutho we-HDMI yovavanyo lwesatifikethi se-Cable yokuhlaziywa okukhulu, isicwangciso esitsha se-DMI Passive Adapter yovavanyo lwesiqinisekiso, kwixesha elidlulileyo phantsi kwe-Ultra High Speed HDMI i-Cable specs zovavanyo, ngaphezu koko kufuneka ixhase umsebenzi we-HEAC, intambo esetyenziselwa ukuhambisa i-HEAC isafuna ukusebenzisa ucingo lobhedu ukuba iqinisekiswe, ukuba isebenzisa i-fiber optical epheleleyo, ayinakuqinisekiswa, kunye ne-Premium High Speed HDMI HEAC umsebenzi phantsi kwentambo. inkcazo yinkxaso yokuzikhethela, emva kokuba olu hlaziyo lwenkcazo lube lukhetho lokuqala kwiskimu sovavanyo lwe-fiber ye-AOC Cable kule nqanaba, i-fiber ecocekileyo ye-HDMI iye yaqatshelwa ngokusemthethweni, ngoku kuthiwa i-HDMI i-fiber transmission kwi-optical hybrid cable ( AOC) kunye nokuhanjiswa kwe-optical yonke into engcono, enyanisweni, ngokuyintloko ixhomekeke ekusebenzeni kweendleko kunye nentengiso yesicelo ukwenza isigqibo, nganye ineenzuzo zayo.
