Whakawhiti whatu
Mai i te 2000, me te whakawhanaketanga o te hangarau whakawhitiwhiti, kua puta mai te whakawhitiwhiti korero muka whatu ki te hangarau whakawhiti waahanga, a, i muri i te 2002, kua puta ano nga hua ororongo HDMI me nga tohu tohu ataata i roto i te waahi o te hikohiko kaihoko.I te Paenga-whāwhā 2002, ko Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba e whitu nga kamupene i hanga tahi i te whakahaere atanga atanga rongorau whakamarama teitei HDMI, ka wehea te tuku HDMI ki te tuku tohu tere-tere me te tuku tohu iti-tere e rua nga waahanga. : 1-12 waewae o 12 4 takirua o nga taura ka whakawhiti i nga tohu tere-tere, ma te whakamahi i te hangarau tohu tohu rerekee TMDS (TMDS (Wai Whakaitihia) i hangaia e Silicon Image Differential Signal) ka whakaiti i te whakawhiti i te hangarau whakawhiti tohu rereke, ko te TMDS he tohu tohu rereke, ma te whakamahi aratau tuku rereke, koinei te kaupapa matua o te hangarau HDMI, i roto i te whakawhiti muka whatu HDMI: enei takirua 4 o 12 TMDS taura e tukuna ana e 4 VCSEL + 4 multimode muka whatu, e taea te whakaoti i te raruraru o te tuku tere tere.I roto i te hongere whakawhiti tere tere HDMI, ko nga 13-19 pine i roto i te HDMI he 7 nga taura hiko: 5V te mana hiko, HPD wera-whakahohe CEC, ipurangi, SDA, SCA, DDC.Ko te taumira whakaatu tino nui ka panui i te hongere DDC: ko te whakahau a te atanga I2C i te puna HDMI hei panui i te E-EDID i te mutunga o te whiwhinga.Ko te I2C, he poto mo te Integrated Circuit Bus, he pahi korero rangatū e whakamahi ana i te hoahoanga rangatira-pononga maha.Ko te kaiwhakaara o I2C tetahi o nga kaihanga o te whakahaere HDMI: Philips Semiconductors.
Ko te nuinga o nga wa e whakamahia ana nga taura HDMI hei hono i nga taputapu ororongo ki nga pouaka whakaata me nga kaitirotiro, no reira ko te nuinga o enei he tuku tawhiti poto, ko te tikanga he 3 mita te roa;Me aha nga kaiwhakamahi ki te hiahia nui ake i te 3 mita?Mena ka whakamahi tonu koe i te waea parahi, ka nui ake te diameter o te waea parahi, ka uaua te piko, ka nui te utu.Na reira, ko te huarahi pai ko te whakamahi i nga muka whatu.Ko te hua o te HDMI AOC optical hybrid cable he hua o te whakaraerae hangarau, ko te kaupapa tuatahi i roto i te whanaketanga kia ko nga taura HDMI 19 katoa he tuku muka whatu, ko te tino tuku muka whatu HDMI, engari na te mea ko nga taura 7 o te iti- whakamahi hongere tere VCSEL+ multimode muka iti-tere tohu whakawaehere me te wetewete he uaua ake, noa te kaiwhakawhanake anake te tohu tere-tere i roto i te 4 takirua o TMDS takere ki VCSEL + multimode tuku muka, te toe 7 waea hiko kei te hono tika tonu e te parahi waeaI kitea i muri i te tukunga o te tohu tere-tere e te muka whatu, na te toronga o te tawhiti tuku tohu TMDS, ka taea te whakawhiti te muka whatu HDMI AOC ki te 100 mita neke atu ranei.Optical fiber HDMI AOC hybrid cable no te mea kei te whakamahi tonu te tohu iti-tere te tuku waea parahi, kua whakatauhia te raru o te tohu tere tere, a kaore ano kia whakatauhia te raru o te tuku tohu konukura iti-tere, na reira he pai ki nga momo hototahi. raruraru i roto i te tuku tawhiti.A ko enei katoa ka taea te whakaoti mena ka whakamahia e te HDMI nga otinga hangarau-a-whatu.Ka whakamahia e te HDMI katoa-whatu nga muka whatu 6, te 4 ki te tuku i nga tohu hongere TMDS tere-tere, 2 ki te tuku tohu HDMI iti-tere, a ka hiahiatia he hiko 5V o waho i te mutunga whakaatu RX hei ngaohiko whakaihiihi mo te whakapiri wera HPD.Whai muri i te tango i te otinga-a-whatu katoa, ka huri te HDMI, te hongere TMDS tere-tere me te hongere DDC iti-tere ki te tuku muka whatu, a ka tino pai ake te tawhiti tuku.
Tautoko mo nga whakaritenga kawa
Ahakoa kua whakaarahia e te raina kakano parahi whatu te tuku ngaronga o nga tohu tawhiti-tawhiti ki te teitei teitei, kei reira tonu te hangarau e whakaoti katoa ana te noho o te waea parahi hei kaikawe whakawhiti, ara, te muka whatu parakore HDMI 2.1 raina, Ko te HDMI 2.1 pure optical active optical cable (AOC) e tino rite ana ki te paerewa HDMI 2.1, ko te tuku tohu kei te whakamahi katoa i te muka whatu, kaore he waea parahi, ko te tuku muka whatu kaore i raro i te pokanoa hiko.Ko te tohu tuku AOC kaore i te kopaki, ko te 48Gbps te nui o te bandwidth, ka taea te tuku whakaahua 8K ultra-tiketike-whakamaramatanga, ko te tawhiti tuku roa ka tae ki te 500m.Ina whakaritea ki nga waea parahi tawhito, he roa ake tenei taura muka, he ngawari, he maamaa, he pai ake te tohu tohu me nga ahuatanga hototahi hiko hiko.I te timatanga o te tau, ko te HDMI Association mo te HDMI Cable tohu tohu tohu tohu mo te whakahou nui, he mahere whakamatautau tohu tohu DMI Passive Adapter hou, i nga wa o mua i raro i nga tohu whakamatautauranga Whakamatau Whakamatau Whakataunga Whakataunga Whakaaturanga Whakaaturanga Whakaaturanga Whakaaturanga Whakaaturanga Whakaaturanga Whakaaturanga, hei taapiri me te tautoko i te mahi HEAC, Ko te taura e whakamahia ana ki te tuku HEAC me whakamahi tonu i te waea parahi kia whakamanahia, mena kei te whakamahi i te muka whatu katoa, kaore e taea te whakamana, a ko te mahi Premium High Speed HDMI HEAC i raro i te tohu taura he tautoko whiriwhiri, i muri i tenei whakahōunga whakahōunga. Ko te whiringa tuatahi mo te kaupapa whakamatautau o te taura AOC muka-katoa i tenei waahanga, ko te HDMI muka parakore kua tino mohiohia, inaianei e kiia ana ko te tuku muka HDMI i roto i te taura hybrid optical (AOC) me te tuku-katoa he pai ake, i roto i te meka, te nuinga tei runga i te mahi utu me te mākete tono ki te whakatau, ia he ona ake painga
