Cishe wonke umuntu enkathini ye-HD uyayazi i-HDMI, ngenxa yokuthi lesi isixhumi esibonakalayo esisakazwa kakhulu sevidiyo ye-HD, futhi incazelo yakamuva ye-2.1A ingasekela nokucaciswa kwevidiyo kwe-8K Ultra HD.Izinto eziyinhloko zomugqa we-HDMI wendabuko ikakhulukazi ithusi, kodwa umugqa wethusi we-HDMI unenkinga, ngoba ukumelana nocingo lwethusi kunokunciphisa okukhulu kwesignali, futhi ukuzinza kokudluliselwa kwesignali ngesivinini esikhulu kuzoba nokukhulu. umthelela ekudluliselweni kwebanga elide.
Uma sithatha isibonelo se-HDMI2.0 esetshenziswa kakhulu kanye ne-HDMI2.1 njengesibonelo, i-HDMI2.0 ingasekela ukuphuma kwevidiyo okufika ku-4K 60Hz, kodwa i-HDMI2.0 ayikusekeli ukuvula i-HDR esimweni se-4K 60Hz yesikhala sombala siyi-RGB, futhi isekela kuphela ukuvula i-HDR KUMODI YOMbala YE-YUV 4:2:2.Lokhu kusho ukudela inani elithile lezindawo ezinemibala ukuze uthole isilinganiso esiphezulu sokuvuselela.Futhi i-HDMI 2.0 ayikusekeli ukudluliswa kwevidiyo engu-8K.
I-HDMI2.1 ayikwazi ukusekela i-4K 120Hz kuphela, kodwa futhi ne-8K 60Hz.I-HDMI2.1 iphinde isekele i-VRR (Isilinganiso Sokuvuselela Okuguquguqukayo).Abadlali bamageyimu kufanele baqaphele ukuthi uma izinga lokuvuselela isikrini lokuphumayo kwekhadi lezithombe nezinga lokuvuselela kabusha lemonitha lingafani, lingase libangele ukudabuka kwesithombe.Indlela elula yokwenza lokhu ukuvula i-VSY, kodwa ukuvula i-VS kuzokhiya inombolo yozimele kokuthi 60FPS, kuthinte umuzwa wegeyimu.
Kulokhu, i-NVIDIA yethule ubuchwepheshe be-G-SYNC, obuxhumanisa ukuvumelanisa idatha phakathi kwesibonisi kanye nokuphumayo kwe-GPU nge-chip, ukuze ukubambezeleka kokuvuselela kwesibonisi kufane ncamashi nokubambezeleka kokuphuma kozimele we-GPU.Ngokufanayo, ubuchwepheshe be-freesync be-AMD.I-VRR (izinga lokuvuselela eliguquguqukayo) lingaqondwa njengokufana nobuchwepheshe be-G-SYNC nobuchwepheshe be-freesync, obusetshenziselwa ukuvimbela isikrini esinyakazayo ukuthi singadabuki noma singingiza, kuqinisekiswe ukuthi isikrini segeyimu sishelela futhi siphelele ngemininingwane. .
Ngesikhathi esifanayo, i-HDMI2.1 futhi iletha i-ALLM (Imodi Yokubambezeleka Okuphansi Okuzenzakalelayo).Abasebenzisi bama-smart TV kumodi yokubambezeleka okuphansi okuzenzakalelayo abashintsheli mathupha kumodi yokubambezeleka okuphansi ngokusekelwe kulokho i-TV edlalayo, kodwa bavumela ngokuzenzakalelayo noma bakhubaze imodi yokubambezeleka okuphansi ngokusekelwe kulokho okudlalwa i-TV.Ngaphezu kwalokho, i-HDMI2.1 iphinde isekele i-HDR enamandla, kuyilapho i-HDMI2.0 isekela kuphela i-HDR emile.
I-superposition yobuchwepheshe obusha obuningi, umphumela ukuqhuma kwedatha yokudlulisa, ngokuvamile, "umkhawulokudonsa wokudlulisa" we-HDMI 2.0 yi-18Gbps, engadlulisela i-3840 * 2160@60Hz (ukusekelwa kokubuka i-4K);ku-HDMI 2.1, umkhawulokudonsa wokudlulisela udinga ukuba ngu-48Gbps, ongadlulisela ku-7680 * 4320@60Hz.Izintambo ze-HDMI nazo zinezici ezibalulekile njengesixhumanisi phakathi kwamadivaysi namatheminali wokubonisa.Isidingo somkhawulokudonsa ophezulu senza izintambo ze-HDMI zefiber optic zizalwe, lapha sizoqhathanisa ukufana nomehluko phakathi kwemigqa evamile ye-HDMI nemigqa ye-optical FIBER HDMI:
(1) Umnyombo awufani
Intambo ye-HDMI ye-optical fiber isebenzisa i-optical fibre core, futhi impahla ngokuvamile i-glass fibre kanye ne-plastic fiber.Uma kuqhathaniswa nezinto ezimbili, ukulahlekelwa kwe-glass fiber kuncane, kodwa izindleko ze-plastic fiber ziphansi.Ukuze uqinisekise ukusebenza, ngokuvamile kuyanconywa ukusebenzisa i-plastic optical fiber ibanga elingaphansi kwamamitha angu-50 kanye ne-glass optical fiber ngaphezu kwamamitha angu-50.Intambo ye-HDMI evamile yenziwe ngocingo oluwumgogodla wethusi, vele, kunezinguqulo ezithuthukisiwe ezifana ne-silver plated copper kanye ne-sterling silver wire.Umehluko wezinto ezibonakalayo unquma umehluko omkhulu phakathi kwentambo ye-HDMI ye-optical fiber kanye nekhebula le-HDMI elivamile emikhakheni yazo.Isibonelo, izintambo ze-fiber optical zizoba mncane kakhulu, zilula futhi zithambe;kuyilapho izintambo ezivamile zethusi zizoba ziminyene kakhulu, zisinda, ziqine njalonjalo.
2) Isimiso sihlukile
Ulayini we-HDMI ye-fiber optical wamukela injini ye-photoelectric conversion chip, edinga ukudluliselwa ngokuguqulwa okubili kwe-photoelectric: enye iyisiginali kagesi ibe isignali yokubona, bese isignali ye-optical idluliselwa kulayini we-fiber optical, bese kuba isignali yokubona. iguqulwa ibe isignali kagesi, ukuze kubonakale ukudluliselwa okusebenzayo kwesiginali ukusuka ekugcineni kwe-SOURCE ukuya ekugcineni kwe-DISPLAY.Imigqa ye-HDMI evamile isebenzisa ukudluliswa kwesignali kagesi futhi ayidingi ukudlula ekuguquleni okubili kwe-photoelectric.
(3) Ukufaneleka kokudlulisela kuhlukile
Njengoba kushiwo ngenhla, uhlelo lwe-chip olusetshenziswa imigqa ye-HDMI ye-optical fiber kanye nemigqa ye-HDMI evamile ihlukile, ngakho-ke kukhona umehluko ekusebenzeni kokudlulisela.Ngokuvamile, ngenxa yokuthi i-photoelectric idinga ukuguqulwa kabili, umehluko ngesikhathi sokudlulisela phakathi komugqa we-fiber optical HDMI kanye nolayini we-HDMI ojwayelekile emgqeni omfushane phakathi kwamamitha angu-10 awumkhulu, ngakho-ke kunzima ukuba nokunqoba okuphelele noma ukunqotshwa. ekusebenzeni kokubili emgqeni omfushane.Imigqa ye-Fiber optic HDMI ingasekela ukudluliswa okungalahleki kwamasiginali ngaphezu kwamamitha ayi-150 ngaphandle kwesidingo seamplifier yesignali.Ngesikhathi esifanayo, ngenxa yokusetshenziswa kwe-fiber optical njengesithwali sokudlulisela, umphumela wokwethembeka okuphezulu kwesiginali ungcono futhi ungcono, futhi ngeke uthinteke emisebeni kagesi yemvelo yangaphandle, efaneleka kakhulu imidlalo kanye nezimboni ezidingeka kakhulu.
(4) Umehluko wamanani mkhulu
Njengamanje, ngenxa yomugqa we-HDMI ye-optical fiber njengento entsha, isikali semboni kanye neqembu lomsebenzisi lincane kakhulu.Ngakho-ke, isikali semigqa ye-HDMI ye-optical fiber sincane, ngakho-ke intengo isesezingeni eliphezulu, ngokuvamile ibiza ngokuphindwe kaningana kunemigqa ye-HDMI yomgogodla wethusi.Ngakho-ke, ulayini we-HDMI oyinhloko yethusi wamanje awukashintshwa ngokuya ngokusebenza kwezindleko.
