Ukudluliswa kwe-Optical
Kusukela ngo-2000, ngokuthuthukiswa kobuchwepheshe bokuxhumana, ukuxhumana kwe-fiber optical kuye kwavela ubuchwepheshe bokudlulisa i-optical module, futhi ngemva kwe-2002, ukuhanjiswa kwedijithali kwe-HDMI imikhiqizo yesignali yomsindo nevidiyo nayo ivele emkhakheni we-electronics yabathengi.Ngo-April 2002, i-Hitachi, i-Panasonic, i-Philips, i-Silicon Image, i-Sony, i-Thomson, i-Toshiba izinkampani eziyisikhombisa zasungula ngokuhlanganyela inhlangano ye-HDMI ye-multimedia interface ye-multimedia, ukuhanjiswa kwe-HDMI kuhlukaniswe ngokudluliswa kwesignali ngesivinini esikhulu kanye nokudlulisa isignali yesivinini esiphansi izingxenye ezimbili. : Izinyawo ezingu-1-12 zamapheya angu-12 4 amakhebuli adlulisa amasignali anesivinini esikhulu, kusetshenziswa ubuchwepheshe bokusayina i-TMDS (i-TMDS (Isikhathi Esincishisiwe) esungulwe i-Silicon Image Differential Signal) kunciphisa ubuchwepheshe bokudlulisa isignali ehlukile, i-TMDS iyindlela yesiginali ehlukile, isebenzisa imodi yokudlulisa ehlukile, okuyisimiso esiyisisekelo sobuchwepheshe be-HDMI, ku-HDMI ye-optical fiber transmission: lezi zipheya ze-4 zezintambo ze-12 TMDS zihanjiswa yi-4 VCSEL + 4 multimode optical fibers, engakwazi ukuxazulula kalula inkinga yokudluliselwa kwesivinini esikhulu.
Esiteshini se-HDMI esinesivinini esiphansi, izikhonkwane ezingu-13-19 ku-HDMI zinezintambo ze-elekthronikhi ezingu-7: ukunikezwa kwamandla angu-5V, ukushintshashintsha okushisayo kwe-HPD kusebenze i-CEC, i-inthanethi, i-SDA, i-SCA, iziteshi ze-DDC.Ukulungiswa kokubonisa okubaluleke kakhulu kufunda isiteshi se-DDC: kungumyalo wesixhumi esibonakalayo se-I2C emthonjeni we-HDMI ukufunda i-E-EDID ekugcineni kokwamukela.I-I2C, emfushane ye-Integrated Circuit Bus, ibhasi lokuxhumana elilandelanayo elisebenzisa i-multi-master-slave architecture.Umsunguli we-I2C futhi ungomunye wabasunguli benhlangano ye-HDMI: Philips Semiconductors.
Izintambo ze-HDMI zivame ukusetshenziselwa ukuxhuma imishini ye-audiovisual kuma-TV nama-monitor, ngakho-ke iningi lazo lidlulisela amabanga amafushane, ngokuvamile amamitha angu-3 kuphela ubude;Yini okufanele abasebenzisi bayenze uma bedinga ngaphezu kwamamitha angu-3?Uma uqhubeka nokusebenzisa ucingo lwethusi, ububanzi bocingo lwethusi buyoba bukhulu, kuzoba nzima ukugoba, futhi izindleko zizoba phezulu.Ngakho-ke, indlela engcono kakhulu ukusebenzisa imicu optical.Umkhiqizo wekhebula le-HDMI AOC optical hybrid empeleni ungumkhiqizo wokuyekethisa kwezobuchwepheshe, inhloso yokuqala ekuthuthukisweni kufanele kube ukuthi zonke izintambo ze-HDMI 19 ziyi-optical fibre transmission, okuyi-HDMI yangempela ye-fiber optical, kodwa ngenxa yokuthi izintambo ezingu-7 ze-low-. Ishaneli esheshayo isebenzisa i-VCSEL+ i-multimode fiber enesivinini esiphansi ukubhala ikhodi kanye nokukhipha ikhodi kunzima kakhulu, umane nje umthuthukisi kuphela isignali enesivinini esiphezulu kumapheya angu-4 weziteshi ze-TMDS kuya ku-VCSEL+ multimode fiber transmission, izintambo zikagesi ezingu-7 ezisele zisaxhunywe ngokuqondile ngethusi. ucingoKwatholakala ukuthi ngemva kokuba isignali yesivinini esiphezulu idluliselwe nge-fiber optical, ngenxa yokwandiswa kwebanga lokudlulisa isignali ye-TMDS, i-fiber optical HDMI AOC ingadluliselwa kumamitha angu-100 noma ngisho nangaphezulu.
Intambo ye-hybrid ye-Optical fiber HDMI AOC ngoba isignali yesivinini esiphansi isasebenzisa ukudluliswa kwentambo yethusi, inkinga yesiginali yesivinini esikhulu iyaxazululwa, futhi inkinga yokudluliselwa kwethusi yesiginali ephansi ayikaxazululwa, ngakho-ke ijwayele ukuhambisana okuhlukahlukene. izinkinga ekudluliselweni kwebanga elide.Futhi konke lokhu kungaxazululwa ngokuphelele uma i-HDMI isebenzisa izixazululo zobuchwepheshe bokubona konke.I-All-optical HDMI isebenzisa imicu yokubona engu-6, engu-4 ukuze idlulise amasiginali wesiteshi se-TMDS enesivinini esikhulu, i-2 ukuze idlulisele amasiginali we-HDMI esivinini esiphansi, kanye nogesi wangaphandle we-5V uyadingeka ekugcineni kwesibonisi se-RX njenge-voltage evusa amadlingozi ye-HPD yokuxhuma.Ngemuva kokwamukela isisombululo se-all-optical, i-HDMI, isiteshi se-TMDS esinesivinini esikhulu kanye nesiteshi se-DDC esinesivinini esiphansi siguqulwa sibe yi-optical fiber transmission, futhi ibanga lokudlulisela lithuthukiswa kakhulu.
Ukusekela ukucaciswa kwephrothokholi
Nakuba umugqa we-hybrid yethusi optical uye waphakamisa ukudluliswa okungalahleki kwezimpawu zebanga elide ukuya ekuphakameni okuphezulu kakhulu, kusekhona ubuchwepheshe obuxazulula ngokuphelele ukuba khona kocingo lwethusi njengomqhubi wokudlulisa, okungukuthi, i-fiber optical ehlanzekile ye-HDMI 2.1 umugqa, Ikhebula le-HDMI 2.1 elihlanzekile optical active optical (AOC) lithobelana ngokugcwele nezinga le-HDMI 2.1, ukudluliswa kwesignali konke kusebenzisa i-fiber optical, ayiqukethe intambo yethusi, ukudluliswa kwe-fiber optical akukho ngaphansi kokuphazanyiswa yi-electromagnetic.Isiginali yokudlulisa ye-AOC ayicindezelwanga, umkhawulokudonsa omkhulu ungu-48Gbps, ungadlulisa ngokuphelele izithombe ze-8K ze-ultra-high-definition, ibanga elide kakhulu lokudlulisela lingafinyelela ku-500m.Uma kuqhathaniswa nezintambo zethusi ezivamile, le ntambo ye-fiber optic yinde, ithambile, ilula, inekhwalithi yesiginali engcono kanye nezici ezihambisana kahle nozibuthe kagesi.Ekuqaleni konyaka, i-HDMI Association for HDMI Cable test specsification test isibuyekezo esikhulu, uhlelo olusha lokuhlola isitifiketi se-DMI Passive Adapter, esikhathini esidlule ngaphansi kokucaciswa kokuhlolwa kwe-Ultra High Speed HDMI Cable, ngaphezu kwalokho kumele kusekele umsebenzi we-HEAC, ikhebuli esetshenziselwa ukudlulisa i-HEAC isadinga ukusebenzisa intambo yethusi ukuze iqinisekiswe, uma isebenzisa i-fiber optical egcwele, ayikwazi ukuqinisekiswa, futhi umsebenzi we-Premium High Speed HDMI HEAC ngaphansi kokucaciswa kwekhebula uwukusekela kokuzithandela, ngemva kokuba lesi sibuyekezo sesicaciso senziwe. inketho yokuqala yohlelo lokuhlola lwekhebula le-AOC yonke le-fiber kulesi sigaba, i-HDMI ehlanzekile ye-fiber ekugcineni isiye yaqashelwa ngokusemthethweni, manje kuthiwa i-HDMI fiber transmission in optical hybrid cable (AOC) kanye nokudluliselwa kwe-optical konke okungcono, empeleni, ikakhulukazi kuncike ekusebenzeni kwezindleko kanye nemakethe yesicelo ukunquma, ngayinye inezinzuzo zayo
