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, usebenzisa i-TMDS iteknoloji yokubonisa umahluko (i-TMDS (ixesha elincitshisiweyo) eliqanjwe yi-Silicon Image Differential Signal) linciphisa ukuhanjiswa kweteknoloji yokuhanjiswa kweempawu, i-TMDS yindlela yesignali eyahlukileyo, usebenzisa imowudi yokudlulisa eyahlukileyo, eyona mgaqo osisiseko we-HDMI iteknoloji, kwi-HDMI ye-fiber optical transmission: ezi zimbini ze-4 zeentambo ze-TMDS ze-12 zihanjiswa yi-4 VCSEL + 4 i-multimode optical fibers, enokuyicombulula ngokulula ingxaki yokuhanjiswa kwesantya esiphezulu.Kwi-HDMI i-channel ye-speed-speed transmission channel, i-13-19 izikhonkwane kwi-HDMI zineentambo ze-elektroniki ze-7: ukunikezelwa kwamandla e-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-. ishaneli yesantya isebenzisa i-VCSEL + i-multimode i-fiber ephantsi kwe-encoding yesignali kunye ne-decoding inzima ngakumbi, ngokulula umphuhlisi kuphela umqondiso wesantya esiphezulu kwiimbini ze-4 zeziteshi ze-TMDS ukuya kwi-VCSEL + i-multimode fiber transmission, i-7 eseleyo iingcingo ze-elektroniki zisaqhagamshelwe ngokuthe ngqo ngobhedu. ucingoKwafunyaniswa ukuba emva kokuba umqondiso we-high-speed uhanjiswe nge-fiber optical, ngenxa yokwandiswa komgama wokudlulisa uphawu lwe-TMDS, i-fiber optical HDMI AOC inokudluliselwa kwiimitha ze-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 kungasombululwa 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 ye-excitation ye-plugging ye-HPD eshushu.Emva kokwamkela isisombululo sonke, i-HDMI, i-speed-speed TMDS ishaneli kunye nesiteshi se-DDC esisezantsi sitshintshwa kwi-fiber optical 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 esebenzayo (i-AOC) ihambelana ngokupheleleyo ne-HDMI 2.1 umgangatho, ukuhanjiswa kwesignali konke kusebenzisa i-fiber optical, ayinayo i-copper wire, ukuhanjiswa kwe-fiber optical ayixhomekeke kukuphazamiseka kwe-electromagnetic.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 wesiginali 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 ukuze iqinisekiswe, ukuba isebenzisa i-fiber optical epheleleyo, ayinakuqinisekiswa, kunye ne-Premium High Speed HDMI umsebenzi we-HEAC phantsi kwenkcazo yentambo yinkxaso yokuzikhethela, emva kokuba olu hlaziyo lubalulwe. ukhetho lokuqala lwesicwangciso sovavanyo lwe-fiber ye-AOC Cable kule nqanaba, i-HDMI ecocekileyo ifayibha iye yaqatshelwa ngokusemthethweni, ngoku kuthiwa i-HDMI i-fiber transmission kwi-optical hybrid cable (AOC) kunye ne-optical transmission engcono, enyanisweni, ubukhulu becala kuxhomekeke ekusebenzeni kweendleko kunye nentengiso yesicelo ukwenza isigqibo, nganye ineenzuzo zayo
