Anenge munhu wese ari muHD era anoziva HDMI, nekuti iyi ndiyo inonyanya kukosha HD vhidhiyo yekufambisa interface, uye yazvino 2.1A yakatarwa inogona kutsigira 8K Ultra HD mavhidhiyo.Chinhu chikuru chetsika yeHDMI mutsara kazhinji mhangura, asi mhangura yemhangura yeHDMI mutsara ine dambudziko, nokuti tambo yemhangura yemhangura ine kuderedzwa kukuru kwechiratidzo, uye kugadzikana kwekumhanya kwechiratidzo chepamusoro kuchavawo nehukuru hukuru. kukanganisa pakufambisa rwendo rurefu.
Kutora ikozvino inowanzo shandiswa HDMI2.0 uye HDMI2.1 semuenzaniso, HDMI2.0 inogona kutsigira kusvika 4K 60Hz vhidhiyo inobuda, asi HDMI2.0 haitsigire kubatidza HDR munyaya ye4K 60Hz nzvimbo yeruvara iRGB, uye inongo tsigira kubatidza HDR mu COLOR Mode yeYUV 4:2:2.Izvi zvinoreva kupira imwe huwandu hwemavara enzvimbo mukutsinhana nechiyero chepamusoro chekuzorodza.Uye HDMI 2.0 haitsigire kutapurirana kwe8K vhidhiyo.
HDMI2.1 haigone kutsigira 4K 120Hz chete, asiwo 8K 60Hz.HDMI2.1 inotsigirawo VRR (Variable Refresh Rate).MaGamers anofanirwa kuziva kuti kana iyo skrini yekuvandudza chiyero cheiyo giraidhi kadhi kubuda uye mwero wekuzorodza wemonitor usingaenderane, zvinogona kukonzera kuti mufananidzo ubve.Nzira iri nyore yekuita izvi ndeye kubatidza VSY, asi kubatidza VS kuchavhara huwandu hwemafuremu pa60FPS, zvichikanganisa chiitiko chemutambo.
Kuti izvi zviitike, NVIDIA yakaunza G-SYNC tekinoroji, iyo inoronga kuwiriranisa data pakati pechiratidziro neGPU inobuda kuburikidza nechip, kuitira kuti kunonoka kuzorodza kwechiratidziro kwakangofanana nekunonoka kweGPU kuburitsa.Saizvozvo, AMD's freesync tekinoroji.VRR (variable refresh rate) inogona kunzwisiswa yakafanana neG-SYNC tekinoroji uye freesync tekinoroji, iyo inoshandiswa kudzivirira iyo yepamusoro-yekukurumidza inofamba chidzitiro kubva kubvaruka kana kubhuroka kuita, kuve nechokwadi chekuti chidzitiro chemutambo chakatsetseka uye chakazara zvizere. .
Panguva imwecheteyo, HDMI2.1 inounzawo ALLM (Automatic Low Latency Mode).Vashandisi ve smart TVs mune otomatiki yakaderera-latency modhi havachinji nemaoko kune yakaderera-latency modhi zvichienderana nezvinotambwa neTV, asi inogonesa kana kudzima yakaderera-latency modhi zvichibva pane zvinotambwa neTV.Mukuwedzera, HDMI2.1 inotsigirawo dynamic HDR, nepo HDMI2.0 inongotsigira static HDR.
Iyo yepamusoro yehuzhinji hutsva matekinoroji, mhedzisiro ndeye kuputika kwe data data, kazhinji, iyo "transmission bandwidth" yeHDMI 2.0 ndeye 18Gbps, inogona kutumira 3840 * 2160@60Hz (rutsigiro rwekuona 4K);kuHDMI 2.1, iyo bandwidth yekufambisa inoda kuve 48Gbps, inogona kutumira 7680 * 4320@60Hz.Mahombekombe eHDMI anewo akakosha hunhu sechinongedzo pakati pezvishandiso uye zviteshi zvekuratidzira.Iko kudiwa kwepamusoro bandwidth kunoita HDMI fiber optic tambo kuberekwa, pano isu tichafananidza kufanana uye mutsauko pakati peyakajairwa HDMI mitsara uye yeOptical FIBER HDMI mitsara:
(1) Mwoyo wacho hauna kufanana
Iyo optical fiber HDMI tambo inoshandisa optical fiber core, uye zvinhu zvacho zvinowanzoita girazi faibha uye plastiki fiber.Kuenzaniswa nemidziyo miviri, kurasikirwa kwegirazi fiber idiki, asi mutengo wepurasitiki fiber wakaderera.Kuti uve nechokwadi chekuita, zvinowanzokurudzirwa kushandisa epurasitiki optical fiber kune madaro ari pasi pe50 metres uye girazi optical fiber kweanopfuura 50 metres.Iyo yakajairwa HDMI waya inogadzirwa nemhangura yepakati waya, hongu, kune akakwidziridzwa shanduro senge sirivheri yakaiswa mhangura uye sterling sirivheri waya.Musiyano wezvinhu unosarudza musiyano mukuru pakati peoptical fiber HDMI tambo uye yakajairwa HDMI tambo muminda yavo.Semuenzaniso, optical fiber tambo dzichava dzakatetepa kwazvo, dzakareruka uye dzakapfava;nepo dzakajairwa copper core waya dzichave dzakakora kwazvo, dzinorema, dzakaoma uye zvichingodaro.
2) Nheyo yacho yakasiyana
Iyo optical fiber HDMI mutsara inotora iyo photoelectric conversion chip injini, inoda kufambiswa neaviri mafotoelectric shanduko: imwe chiratidzo chemagetsi muchiratidzo chemaziso, uye ipapo chiratidzo chemaziso chinofambiswa mumutsara wefiber, uye ipapo chiratidzo chemagetsi. inoshandurwa kuita chiratidzo chemagetsi, kuitira kuti uone kufambiswa kunoshanda kwechiratidzo kubva kuSOURCE kumagumo kusvika kumagumo eDISPLAY.Yakajairika HDMI mitsetse inoshandisa magetsi chiratidzo chekufambisa uye haidi kupfuura nepakati pemafotoelectric shanduko.
(3) Iko kutapurirana kwechokwadi kwakasiyana
Sezvambotaurwa pamusoro apa, iyo chip chirongwa chinoshandiswa ne optical fiber HDMI mitsara uye yakajairwa HDMI mitsara yakasiyana, saka kunewo misiyano mukufambisa kwekufambisa.Kazhinji kutaura, nekuti iyo photoelectric inoda kushandurwa kaviri, mutsauko wenguva yekufambisa pakati peiyo optical fiber HDMI mutsara uye yakajairika HDMI mutsara pamutsara mupfupi mukati me10 metres haisi yakakura, saka zvakaoma kuve nekukunda kwakakwana kana kukundwa. mukuita kwevaviri pamutsara mupfupi.Fiber optic HDMI mitsetse inogona kutsigira kusarasikirwa kutapurirana kwemasaini pamusoro pe150 metres pasina kudiwa kwechiratidzo cheamplifier.Panguva imwecheteyo, nekuda kwekushandiswa kwefiber optical semutakuri wekutapurirana, kutendeseka kwepamusoro kwechiratidzo kuri nani uye kuri nani, uye hakuzokanganiswe nemwaranzi yemagetsi yenzvimbo yekunze, iyo yakakodzera kwazvo mitambo uye maindasitiri anodiwa zvakanyanya.
(4) Musiyano wemutengo wakakura
Parizvino, nekuda kweiyo optical fiber HDMI mutsara sechinhu chitsva, iyo indasitiri chiyero uye boka revashandisi idiki.Saka pazere, chiyero che optical fiber HDMI mitsetse idiki, saka mutengo uchiri padanho repamusoro, kazhinji kanoverengeka kudhura kupfuura copper core HDMI mitsetse.Naizvozvo, yazvino yakajairwa mhangura yepakati HDMI mutsara ichiri isingachinjike maererano nemutengo wekuita.
