Ikwirakwizwa ryiza
Kuva mu 2000, hamwe n’iterambere ry’ikoranabuhanga mu itumanaho, itumanaho rya fibre optique ryagaragaye hifashishijwe ikoranabuhanga rya optique yohereza, kandi nyuma ya 2002, ibicuruzwa byerekana amajwi n'amashusho HDMI byifashishijwe mu bikoresho bya elegitoroniki.Muri Mata 2002, Hitachi, Panasonic, Philips, Ishusho ya Silicon, Sony, Thomson, Toshiba amasosiyete arindwi yafatanyije gushinga ishyirahamwe ry’imikorere ya interineti ya HDMI yo mu rwego rwo hejuru, imiyoboro ya HDMI igabanyijemo ibice byihuta kandi byohereza ibimenyetso byihuta ibice bibiri . uburyo bwo kohereza butandukanye, niryo hame ryibanze ryikoranabuhanga rya HDMI, mugukwirakwiza fibre optique HDMI: izi 4 zombi zinsinga 12 za TMDS zoherejwe na 4 VCSEL + 4 ya fibre optique ya fibre optique, ishobora gukemura byoroshye ikibazo cyo kwanduza byihuse.Mu muyoboro wa HDMI wihuta, imiyoboro 13-19 muri HDMI ifite insinga 7 za elegitoronike: 5V itanga amashanyarazi, HPD hot-swap ikora CEC, interineti, SDA, SCA, DDC.Ibyingenzi byingenzi byerekana imyanzuro isoma umuyoboro wa DDC: ni itegeko rya I2C ya interineti kuri HDMI isoko yo gusoma E-EDID kurangiza.I2C, ngufi kuri Bus Yuzuzanya Yumuzingi, ni bisi itumanaho ikurikirana ikoresha ubwinshi-shobuja-imbata.Uwatangije I2C kandi numwe mubashinze umuryango HDMI: Philips Semiconductor.
Ubusanzwe insinga za HDMI zikoreshwa muguhuza ibikoresho byamajwi n'amashusho kuri TV na monitor, bityo ibyinshi muribyo byohereza intera ngufi, mubisanzwe metero 3 gusa;Abakoresha bagomba gukora iki niba bakeneye metero zirenga 3?Niba ukomeje gukoresha insinga z'umuringa, diameter ya wire y'umuringa izaba nini, bizagorana kunama, kandi ikiguzi kizaba kinini.Kubwibyo, inzira nziza nugukoresha fibre optique.HDMI AOC optique ya Hybrid yamashanyarazi mubyukuri nibicuruzwa byumvikanyweho na tekiniki, intego yambere mugutezimbere igomba kuba ko insinga zose za HDMI 19 ari fibre optique yoherejwe, aribwo buryo bwiza bwo gukwirakwiza fibre optique HDMI, ariko kubera ko insinga 7 zo hasi- umuyoboro wihuta ukoreshe VCSEL + multimode fibre yihuta ya signal ya kodegisi na decoding biragoye, gusa uwatezimbere gusa ibimenyetso byihuta gusa mumirongo 4 yimiyoboro ya TMDS kuri VCSEL + fibre fibre fibre, insinga 7 za elegitoronike zisigaye ziracyahujwe numuringa. wire Byagaragaye ko nyuma yikimenyetso cyihuta cyoherejwe na fibre optique, kubera kwagura intera yoherejwe na signal ya TMDS, fibre optique HDMI AOC ishobora kwanduzwa metero 100 cyangwa ndende.Optical fibre HDMI AOC ya kabili kuko ibimenyetso byihuta biracyakoresha insinga zumuringa, ikibazo cyumuvuduko mwinshi cyarakemutse, kandi ikibazo cyo kohereza umuringa wihuta cyumuringa ntikiracyemuka, kuburyo gikunze guhuzwa muburyo butandukanye ibibazo mugukwirakwiza intera ndende.Kandi ibyo byose birashobora gukemurwa rwose niba HDMI ikoresha ibisubizo byose bya tekinoroji.All-optique HDMI ikoresha fibre 6 optique, 4 kugirango yohereze ibimenyetso byihuta byumuyoboro wa TMDS, 2 yohereza ibyuma byihuta bya HDMI, kandi amashanyarazi 5V yo hanze arasabwa kumpera ya RX yerekanwe nkumubyigano wibyishimo kuri HPD.Nyuma yo gufata igisubizo cyose-optique, HDMI, umuyoboro wihuse wa TMDS numuyoboro muke wa DDC wihuta uhindurwamo fibre optique, kandi intera yoherejwe iratera imbere cyane.
Inkunga ya protocole ibisobanuro
Nubwo umurongo wa optique wumuringa wazamuye uburyo bwo gutakaza ibimenyetso byintera ndende kugeza murwego rwo hejuru cyane, haracyari tekinoroji ikemura byimazeyo kubaho insinga zumuringa nkumuyoboro wogukwirakwiza, ni ukuvuga fibre optique fibre HDMI 2.1, HDMI 2.1 ya optique ikora neza ya optique (AOC) yujuje byuzuye na HDMI 2.1 isanzwe, kohereza ibimenyetso byose bikoresha fibre optique, ntabwo irimo insinga z'umuringa, fibre optique ntishobora gukoreshwa na electronique.Ikimenyetso cyo kohereza AOC ntigihagarikwa, umurongo ntarengwa ni 48Gbps, urashobora kohereza neza 8K ultra-high-definition-amashusho, intera ndende ishobora kugera kuri 500m.Ugereranije ninsinga zumuringa gakondo, iyi fibre optique ni ndende, yoroshye, yoroshye, hamwe nibimenyetso byiza kandi biranga amashanyarazi meza.Mu ntangiriro z'umwaka, Ishyirahamwe rya HDMI rya HDMI Cable ibyemezo byerekana ibizamini byerekana ivugurura rikomeye, gahunda y'ibizamini bya DMI Passive Adapter nshya, mu bihe byashize munsi y'ibizamini bya Ultra High Speed HDMI Cable, usibye no gushyigikira imikorere ya HEAC, insinga ikoreshwa mu kohereza HEAC iracyakeneye gukoresha insinga z'umuringa kugirango zemezwe, niba ikoresha fibre optique yuzuye, ntishobora kwemezwa, kandi imikorere ya Premium High Speed HDMI HEAC munsi yumurongo wa kabili ni inkunga itabishaka, nyuma yiri vugurura ryibisobanuro rimaze kuba ihitamo rya mbere kuri gahunda yikizamini cya fibre yose ya AOC Cable muriki cyiciro, fibre fibre HDMI yarangije kumenyekana kumugaragaro, ubu bivugwa ko kwanduza fibre ya HDMI mumashanyarazi ya optique (AOC) hamwe nogukwirakwiza optique nibyiza, mubyukuri, ahanini biterwa nigikorwa cyibiciro nisoko ryo gusaba guhitamo, buriwese afite ibyiza bye
