Felauaiga mata'utia
Talu mai le 2000, faʻatasi ai ma le atinaʻeina o tekinolosi fesoʻotaʻiga, o fesoʻotaʻiga fiber opitika ua faʻaalia ai le tekonolosi faʻaogaina o le module, ma ina ua maeʻa le 2002, o faʻasalalauga faʻasalalau HDMI leo ma faʻailoga vitio ua faʻaalia foi i le tulaga o mea tau eletise.Ia Aperila 2002, Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba kamupani e fitu na faʻatūina faʻatasi le HDMI faʻamalamalamaga maualuga fesoʻotaʻiga fesoʻotaʻiga faʻasalalauga faʻalapotopotoga, o le HDMI faʻasalalau ua vaevaeina i luga o le saosaoa faʻasalalau faʻasalalauga ma le maualalo-saosaoa faʻasalalauga faʻasalalauga vaega e lua. : 1-12 futu o le 12 4 paipa o uaea auina atu faailoilo maualuga-saosaoa, e faaaoga ai le TMDS differential signaling technology (TMDS (Time Minimized) invented by Silicon Image Differential Signal) faʻaitiʻitia le tuʻuina atu o faʻasalalauga faʻasalalauga faʻasalalauga, TMDS o se masini faʻailoga eseese, faʻaaogaina faʻasalalauga faʻasalalauga tulaga, o le mataupu faavae autu o le tekonolosi HDMI, i le faʻaogaina o le fiber opitika HDMI: o nei 4 paipa o 12 TMDS uaea o loʻo tuʻuina atu e 4 VCSEL + 4 multimode fiber optical, lea e mafai ona faigofie ona foia le faʻafitauli o le televave o fesoʻotaʻiga.I le HDMI low-speed transmission channel, o le 13-19 pine i HDMI o loʻo i ai 7 eletise eletise: 5V power supply, HPD hot-swap activates CEC, initaneti, SDA, SCA, DDC auala.O le faʻaaliga sili ona taua e faitau le DDC channel: o le faʻatonuga a le I2C interface i le puna HDMI e faitau ai le E-EDID i le pito e mauaina.I2C, fa'apuupuu mo le Integrated Circuit Bus, ose pasi feso'ota'iga fa'asologa e fa'aogaina ai le fa'ailoga tele-matai-pologa.O le amataga o le I2C o se tasi foi lea na faavaeina le faalapotopotoga HDMI: Philips Semiconductors.
O laina HDMI e masani ona faʻaogaina e faʻafesoʻotaʻi ai mea faʻalogo i TV ma mataʻituina, o le tele o ia mea e puʻupuʻu mamao, e masani lava na o le 3 mita le umi;O le a le mea e tatau ona fai e tagata fa'aoga pe a latou mana'omia le sili atu i le 3 mita?Afai e te faʻaauau pea ona faʻaaogaina uaea kopa, o le a faʻateleina le lautele o le uaea apamemea, o le a faigata ona punou, ma o le a maualuga le tau.O le mea lea, o le auala sili o le faʻaaogaina o filo opitika.HDMI AOC optical hybrid cable oloa o le mea moni lava o se oloa o fetuunaiga faʻapitoa, o le uluaʻi faʻamoemoega i le atinaʻe e tatau ona faʻapea uma HDMI 19 uaea o felauaiga fibre opitika, o le felauaiga alava mata moni HDMI, ae ona o le 7 uaea o le maualalo- auala saoasaoa fa'aoga VCSEL + multimode fiber low-speed signal encoding ma decoding e sili atu ona faigata, na o le atina'e na'o le maualuga-saosaoa faailoilo i le 4 paipa o TMDS auala i VCSEL + multimode fiber transmission, o lo'o totoe 7 uaea eletise o lo'o feso'ota'i sa'o lava i le kopa. uaeaNa maua ina ua uma ona tuʻuina atu le faʻailoga maualuga e ala i le fiber opitika, ona o le faʻalauteleina o le mamao o le tuʻuina atu o faailoilo TMDS, e mafai ona tuʻuina atu le fiber optical HDMI AOC i le 100 mita pe sili atu foi.Optical fiber HDMI AOC hybrid cable ona o le faʻailoga maualalo o loʻo faʻaaogaina pea le uaea apamemea, ua foia le faʻafitauli o le faʻailoga maualuga, ma e leʻi foia le faʻafitauli o le faʻaogaina o le kopa eletise maualalo, o lea e faigofie ai ona faʻafetaui eseese. fa'afitauli ile felauaiga mamao.Ma o nei mea uma e mafai ona foia atoatoa pe a faʻaogaina e le HDMI fofo faʻatekonolosi uma.E fa'aogaina uma e le HDMI fa'aogaina le 6 alava opitika, 4 e tu'uina atu fa'ailo alalaupapa TMDS maualuga, 2 e tu'uina atu fa'ailo maualalo le saoasaoa o le HDMI, ma e mana'omia se sapalai eletise 5V i fafo i le pito fa'aaliga RX e pei o le voltage fa'afiafia mo le fa'apipi'iina o le vevela HPD.A maeʻa ona faʻaaogaina le faʻaogaina uma, HDMI, televave TMDS alalaupapa ma le maualalo-saoasaoa auala DDC ua suia i opitika fiber transmission, ma le felauaiga mamao ua matua faaleleia.
Lagolago mo faʻamatalaga faʻapitoa
E ui lava o le laina eletise apamemea opitika ua siitia ai le leiloa o faailoilo mamao mamao i se maualuga maualuga, o loo i ai pea se tekinolosi e foia atoatoa ai le i ai o le uaea apamemea e avea o se taʻavale feaveaʻi, o lona uiga, mama opitika HDMI 2.1 laina, HDMI 2.1 mama opitika opitika uaea (AOC) tausisia atoatoa le HDMI 2.1 tulaga, fa'ailo fa'aoga uma e fa'aoga alava mata, e le o iai le uaea kopa, fa'alava fa'apipi'i e le noatia i fa'alavelave fa'aeletonika.O le faʻailoga o le AOC e le faʻapipiʻiina, o le maualuga o le bandwidth o le 48Gbps, e mafai ona faʻafeiloaʻi atoatoa ata 8K ultra-high-definition, o le mamao sili ona umi e mafai ona oʻo i le 500m.Pe a faatusatusa i uaea apamemea masani, o lenei uaea fiber optic e umi, vaivai, mama, ma sili atu le lelei o faailoilo ma uiga fetaui lelei electromagnetic.I le amataga o le tausaga, o le HDMI Association mo HDMI Cable faʻamaonia faʻamatalaga faʻataʻitaʻiga mo se faʻafouga tele, fou DMI Passive Adapter suʻega suʻega fuafuaga, i le taimi ua tuanaʻi i lalo ole Ultra High Speed HDMI Cable faʻataʻitaʻiga faʻataʻitaʻiga, faʻaopoopo i le tatau ona lagolagoina galuega HEAC, o le uaea faʻaaogaina e faʻafeiloaʻi ai le HEAC e manaʻomia pea le faʻaogaina o le uaea kopa e faʻamaonia, pe afai o loʻo faʻaaogaina le filo opitika atoatoa, e le mafai ona faʻamaonia, ma Premium High Speed HDMI HEAC galuega i lalo o le faʻamatalaga uaea o le lagolago e filifili, pe a maeʻa lenei faʻamatalaga faʻamatalaga ua avea O le filifiliga muamua mo le suʻega o faʻataʻitaʻiga uma-fiber AOC Cable i lenei laasaga, ua maeʻa ona aloaia aloaia HDMI alava mama, o lea ua fai mai o le HDMI fiber transmission i optical hybrid cable (AOC) ma felauaiga uma-optical e sili atu, i le mea moni, e faalagolago tele i le tau faatinoga ma maketi talosaga e filifili ai, e tofu lava ma ona lava lelei
