Phantse wonke umntu kwixesha le-HD uyayazi i-HDMI, kuba le yeyona ndlela iphambili yokuhanjiswa kwevidiyo ye-HD, kwaye inkcazo yamva nje ye-2.1A inokuxhasa i-8K Ultra HD inkcazo yevidiyo.Izinto eziphambili zomgca we-HDMI yendabuko ininzi yobhedu, kodwa umgca we-HDMI yobhedu unobungozi, kuba ukuchasana kocingo lwe-copper kunokunciphisa umqondiso omkhulu, kwaye ukuzinza kokudluliselwa kwesignali yesantya esiphezulu kuya kuba nako enkulu. ifuthe kuthumelo lomgama omde.
Ukuthatha i-HDMI2.0 esetyenziswa ngokuqhelekileyo ngoku kunye ne-HDMI2.1 njengomzekelo, i-HDMI2.0 inokuxhasa ukuya kuthi ga kwi-4K 60Hz imveliso yevidiyo, kodwa i-HDMI2.0 ayixhasi ukuvula i-HDR kwimeko ye-4K 60Hz indawo yombala yi-RGB, kwaye ixhasa kuphela ukulayita i-HDR KWIMODI YOMbala yeYUV 4:2:2.Oku kuthetha ukuncama ubungakanani obuthile bomphezulu wombala ukutshintshiselana ngezinga eliphezulu lokuhlaziya.Kwaye i-HDMI 2.0 ayikuxhasi ukuhanjiswa kwevidiyo ye-8K.
I-HDMI2.1 ayinakuxhasa kuphela i-4K 120Hz, kodwa kunye ne-8K 60Hz.I-HDMI2.1 iphinde ixhase i-VRR (i-Variable Refresh Rate).Abadlali kufuneka baqonde ukuba xa ireyithi yokuhlaziya isikrini sokuphuma kwekhadi lemizobo kunye nezinga lokuhlaziya i-monitor lingahambelani, kunokubangela ukuba umfanekiso ukrazuke.Eyona ndlela ilula yokwenza oku kukuvula i-VSY, kodwa ukuvula i-VS kuya kutshixa inani lezakhelo kwi-60FPS, echaphazela amava omdlalo.
Ukuza kuthi ga ngoku, i-NVIDIA yazisa itekhnoloji ye-G-SYNC, elungelelanisa ulungelelwaniso lwedatha phakathi komboniso kunye nemveliso ye-GPU ngechip, ukuze ukulibaziseka kokuhlaziya umboniso kufane kanye nokulibaziseka kwesakhelo se-GPU.Ngokufanayo, itekhnoloji ye-AMD ye-freesync.I-VRR (izinga lokuhlaziya eliguquguqukayo) linokuqondwa njengelinye itekhnoloji ye-G-SYNC kunye netekhnoloji ye-freesync, esetyenziselwa ukuthintela isikrini esishukumayo esinesantya esiphezulu ukuba sikrazule okanye sithintithe, siqinisekise ukuba isikrini somdlalo sigudileyo kwaye siphelele ngakumbi ngokweenkcukacha. .
Ngexesha elifanayo, i-HDMI2.1 izisa i-ALLM (iMode ye-Automatic Low Latency Mode).Abasebenzisi bee-TV ezihlakaniphile kwimowudi ye-latency ephantsi ngokuzenzekelayo abatshintsheli kwimowudi ye-latency ephantsi ngokusekwe kwinto edlalwa yiTV, kodwa ngokuzenzekelayo bavule okanye bavale imowudi ye-latency ephantsi ngokusekwe kwinto edlalwa yiTV.Ukongeza, i-HDMI2.1 iphinde ixhase i-HDR eguquguqukayo, ngelixa i-HDMI2.0 ixhasa kuphela i-HDR emileyo.
I-superposition yobuchwephesha obutsha obuninzi, umphumo kukuqhuma kwedatha yokudlulisa, ngokubanzi, "i-bandwidth yokudlulisa" ye-HDMI 2.0 yi-18Gbps, enokudlulisa i-3840 * 2160@60Hz (inkxaso yokujonga i-4K);ukuya kwi-HDMI 2.1, i-bandwidth yokudlulisa kufuneka ibe yi-48Gbps, enokudlulisa i-7680 * 4320@60Hz.Iintambo zeHDMI zineempawu eziyimfuneko njengekhonkco phakathi kwezixhobo kunye neetheminali zokubonisa.Isidingo se-bandwidth ephezulu yenza i-HDMI intambo ye-fiber optic izalwe, apha siza kuthelekisa ukufana kunye nomahluko phakathi kwemigca ye-HDMI eqhelekileyo kunye nemigca yeFIBER HDMI yokubona:
(1) Undoqo awufani
Intambo ye-HDMI ye-fiber optical isebenzisa i-fiber optical core, kwaye izinto eziphathekayo ziyi-fiber yeglasi kunye ne-plastic fiber.Xa kuthelekiswa nezinto ezimbini, ilahleko yefiber yeglasi incinci, kodwa ixabiso lefiber yeplastiki liphantsi.Ukuqinisekisa ukusebenza, kuyacetyiswa ngokubanzi ukuba kusetyenziswe iplastiki yefiber optical kumgama ongaphantsi kweemitha ezingama-50 kunye neglasi yefiber optical ngaphezu kweemitha ezingama-50.Ucingo oluqhelekileyo lwe-HDMI lwenziwe ngocingo oluphambili lwe-copper, ngokuqinisekileyo, kukho iinguqulelo eziphuculweyo ezifana nesilivere efakwe ubhedu kunye ne-sterling silver wire.Umahluko kwizinto eziphathekayo unquma umahluko omkhulu phakathi kwentambo ye-HDMI ye-optical fiber kunye nentambo ye-HDMI eqhelekileyo kwiindawo zabo.Ngokomzekelo, iintambo ze-fiber optical ziya kuba zincinci kakhulu, zilula kwaye zithambile;ngelixa iingcingo zobhedu eziqhelekileyo ziya kuba nzima kakhulu, zibe nzima, zibe nzima njalo njalo.
2) Umgaqo uhlukile
I-fiber optical HDMI umgca wamkela i-injini ye-photoelectric conversion chip, efuna ukuhanjiswa ngokuguqulwa kwe-photoelectric ezimbini: enye yisignali yombane kwi-signal optical, kwaye emva koko i-optical signal idluliselwa kumgca we-fiber optical, kwaye emva koko i-optical signal. iguqulwa ibe ngumqondiso wombane, ukwenzela ukuba uqaphele ukuhanjiswa okusebenzayo kwesignali ukusuka kwi-SOURCE ekupheleni ukuya ekupheleni kwe-DISPLAY.Imigca ye-HDMI eqhelekileyo isebenzisa ukuhanjiswa kwesignali yombane kwaye ayifuni ukudlula kwiinguqu ezimbini ze-photoelectric.
(3) Ukuqinisekiswa kokudluliselwa kuyahluka
Njengoko kukhankanyiwe ngasentla, i-chip scheme esetyenziswa yi-optical fiber imigca ye-HDMI kunye nemigca ye-HDMI eqhelekileyo iyahluka, ngoko ke kukho ukungafani ekusebenzeni kokuhanjiswa.Ngokuqhelekileyo, ngenxa yokuba i-photoelectric idinga ukuguqulwa kabini, umehluko kwixesha lokuhambisa phakathi kwe-fiber optical HDMI umgca kunye nomgca we-HDMI oqhelekileyo kumgca omfutshane ngaphakathi kweemitha ezili-10 awukho mkhulu, ngoko kunzima ukuphumelela ngokupheleleyo okanye ukunqotshwa. ekusebenzeni kwezi zibini kumgca omfutshane.Imigca ye-Fiber optic HDMI inokuxhasa ukuhanjiswa kweempawu ezilahlekileyo ngaphezulu kweemitha ezili-150 ngaphandle kwesidingo sesandisi-lizwi.Kwangaxeshanye, ngenxa yokusetyenziswa kwefiber optical njengomphathi wothumelo, isiphumo sokuthembeka okuphezulu kophawu singcono kwaye singcono, kwaye asiyi kuchaphazeleka yimitha ye-electromagnetic yendalo yangaphandle, eyilungele kakhulu. imidlalo kunye namashishini anemfuno ephezulu.
(4) Umahluko wamaxabiso mkhulu
Okwangoku, ngenxa yomgca we-fiber optical HDMI njengento entsha, isikali soshishino kunye neqela lomsebenzisi lincinci.Ngoko ke, umlinganiselo wemigca ye-HDMI ye-fiber optical incinci, ngoko ke ixabiso lisekwizinga eliphezulu, ngokuqhelekileyo amaxesha amaninzi abiza kakhulu kune-copper core HDMI imigca.Ngoko ke, umgca we-HDMI we-copper oqhelekileyo wangoku awukatshintshi ngokubhekiselele ekusebenzeni kweendleko.
