Tekinoroji Overview yeHDMI 2.1b Tsanangudzo
Kune vanoda maodhiyo nemavhidhiyo, iyo inonyanya kuzivikanwa midziyo pasina mubvunzo ndeye HDMI tambo uye mainterface. Kubva pakaburitswa iyo 1.0 vhezheni yeHDMI yakatarwa muna 2002, yave nemakore anopfuura makumi maviri. Kwemakore makumi maviri-pamwe nemakore apfuura, HDMI yakave inonyanya kushandiswa kushandiswa kwemaitiro mumavhidhiyo nemavhidhiyo madivayiri. Zvinoenderana nerekodhi rekodhi, huwandu hwekutumira hweHDMI zvishandiso hwasvika 11 bhiriyoni zvikamu, izvo zvakaenzana neanoda kusvika maviri eHDMI zvishandiso pamunhu pasi rose. Kubatsira kukuru kweHDMI ndiko kufanana kwechiyero chayo. Kwemakore makumi maviri apfuura, saizi yemuviri yeyakajairwa HDMI interface yakaramba isina kuchinjika, uye software protocol yakawana kuseri kunoenderana. Izvi zvinonyanya kukodzera kumidziyo mikuru yemumba ine inononoka kugadzirisa hardware, kunyanya terevhizheni. Kunyangwe iyo TV kumba iri modhi yekare kubva pamakore gumi apfuura, inogona kubatana zvakananga kune ichangoburwa-chizvarwa mutambo consoles pasina kudiwa kwemaadapter. Naizvozvo, mumakore achangopfuura, HDMI yakakurumidza kutsiva iyo yapfuura chikamu vhidhiyo, AV, odhiyo, uye mamwe mainterfaces paterevhizheni uye yave inonyanya kuzivikanwa interface paterevhizheni. Zvinoenderana nenhamba, zvese zvigadzirwa zveterevhizheni pamusika muna 2024 zvinoshandisa HDMI tekinoroji, uye HDMI yakave zvakare inotakura yakanakisa yemhando yepamusoro-tsanangudzo mafomati akadai se4K, 8K, uye HDR. Iyo HDMI 2.1a yakajairwa yakakwidziridzwa zvakare: ichawedzera masimba ekupa masimba kumatambo uye inoda kuisirwa machipisi mumidziyo yekushandisa.
Iyo HDMI® Specification 2.1b ndiyo yazvino vhezheni yeHDMI® Kutsanangurwa, inotsigira huwandu hwepamusoro mavhidhiyo resolution uye mitengo yekuvandudza, kusanganisira 8K60 uye 4K120, pamwe nekugadziriswa kusvika ku10K. Iyo zvakare inotsigira ane simba HDR mafomati, ane bandwidth simba rinowedzera kusvika ku48Gbps HDMI. Iyo itsva Ultra High Speed HDMI tambo dzinotsigira 48Gbps bandwidth. Aya tambo anovimbisa kupihwa kweyekupedzisira-yepamusoro bandwidth yakazvimirira maficha, kusanganisira isina kudzvanywa 8K vhidhiyo ine HDR rutsigiro. Ivo vane Ultra-yakaderera EMI (electromagnetic interference), inoderedza kukanganiswa nemidziyo isina waya iri pedyo. Iwo matambo ari kumashure anowirirana uye anogona zvakare kushandiswa nearipo HDMI zvishandiso.
Zvimiro zveHDMI 2.1b zvinosanganisira:
Kugadziriswa kwevhidhiyo yepamusoro: Inogona kutsigira huwandu hwezvisarudzo zvepamusoro uye nekukurumidza kuzorodza mitengo (kusanganisira 8K60Hz uye 4K120Hz), ichipa inonyudza yekuona ruzivo uye yakatsetseka inokurumidza kufamba-famba. Iyo inotsigira kugadziriswa kwekusvika ku10K, kusangana nezvinodiwa zvekutengesa AV, maindasitiri, uye hunyanzvi kunyorera.
Dynamic HDR inova nechokwadi chekuti chiitiko chega chega uye chero furemu yevhidhiyo inoratidza akakodzera kukosha kwekudzika, ruzivo, kupenya, kusiyanisa, uye yakafara ruvara gamut.
Source-based tone mepu (SBTM) chinhu chitsva cheHDR. Kunze kwemepu yeHDR inopedzwa nemudziyo wekuratidzira, zvakare inogonesa sosi mudziyo kuita chikamu chemepu yeHDR. SBTM inonyanya kubatsira pakubatanidza mavhidhiyo eHDR uye SDR kana mifananidzo mumufananidzo mumwe chete, semufananidzo-mu-pikicha kana mapurogiramu epurogiramu ane mahwindo evhidhiyo akabatanidzwa. SBTM inobvumirawo PC nemidziyo yemitambo kuti igadzire otomatiki masaini eHDR kuti aite zvakanyanya kugona kweHDR kwechiratidziro pasina kudikanwa kwekugadziriswa kwemanyorero kweiyo sosi mudziyo.
Ultra-high-speed HDMI tambo dzinogona kutsigira isina kudzvanywa HDMI 2.1b basa uye 48G bandwidth yainotsigira. Iyo EMI yakaburitswa kubva kumatambo yakadzikira. Iwo zvakare ari kumashure anoenderana neakare mavhezheni eHDMI chiyero uye anogona kushandiswa nearipo HDMI zvishandiso.
Iyo HDMI 2.1b yakatarwa inotsiva 2.0b, nepo 2.1a yakatarwa ichiramba ichireva uye kuvimba neHDMI 1.4b yakatarwa. HDMI®
Nzira yekuzivikanwa yeHDMI 2.1b zvigadzirwa
Iyo HDMI 2.1b yakatarwa inosanganisira tambo nyowani - Ultra High-Speed HDMI® Cable. Ndiyo chete tambo inoenderana nezvakatemwa zvakatemwa, ichivavarira kuve nechokwadi cherutsigiro rwese HDMI 2.1b mabasa, kusanganisira isina kudzvanywa 8k@60 uye 4K@120. Iyo yakawedzerwa bandwidth kugona kwetambo iyi inotsigira kusvika ku48Gbps. Ese tambo dzakasimbiswa dzehurefu hupi zvadzo dzinofanirwa kupasa zvitupa bvunzo dzeHDMI Forum Authorized Testing Center (Forum ATC). Kana yapihwa chitupa, tambo ichada kuve neiyo Ultra High-Speed HDMI certification label yakanamirwa pasuru yega yega kana yekutengesa unit, kuitira kuti vatengi vaone mamiriro echitupa chechigadzirwa. Kuti uone tambo, ita shuwa kuti inodiwa Ultra High-Speed HDMI certification label sezvaratidzwa pamusoro inoratidzwa pakapeji. Ziva kuti iyo official cable zita logo yakadhindwa pane iyo label. Iri zita rinodawo kuoneka pane rekunze sheath yetambo. Kuti uone kana tambo yakayedzwa uye yakasimbiswa uye inoenderana neHDMI 2.1b yakatarwa, unogona kutarisisa kodhi yeQR pane iyo label uchishandisa HDMI cable certification application inowanikwa muApple App Store, Google Play Store, uye zvimwe Android application zvitoro.
Iyo yakajairwa HDMI 2.1b version data cable ine 5 pairs dzewaya dzakamonyoroka mukati metambo, nekunze kweruvara kutevedzana kuri yeyero, orenji, chena, tsvuku, uye kune 2 mapoka ekubatanidza kune yakazara 6 waya, ichiita huwandu hwe21 waya. Parizvino, mhando yeHDMI tambo dzinosiyana zvakanyanya uye kune misiyano yakakura. Kusagadzikana kwacho kunopfuura fungidziro. Vamwe vagadziri vanogona kugadzira 3-mita yakapera zvigadzirwa ne30AWG waya dzinosangana neEMI miyero uye dzine bandwidth ye18G, nepo vamwe vagadziri 'waya dzakabviswa dzine bandwidth ye13.5G chete, vamwe vane bandwidth ye10.2G chete, uye vamwe vanotova nebandwidth ye5G chete. Neraki, iyo HDMI Association ine yakadzama yakatarwa, uye nekuienzanisa, munhu anogona kuona kunaka kwetambo. Iyo yazvino tambo dhizaini tsananguro: iyo aluminium foil waya mu5P package inoshandiswa kufambisa data uye rimwe boka reDDC masiginecha ekutaurirana protocol. Mabasa ewaya 7 dzemhangura ndeaya: imwe yemagetsi, imwe yeCEC basa, maviri ekudzoreredza odhiyo (ARC), rimwe boka rezviratidzo zveDDC (waya mbiri dzepakati dzine furo uye imwe pasi waya ine aluminium foil shielding) yekutaurirana protocol. Sarudzo dzezvinhu zvakasiyana-siyana uye musanganiswa webasa zvinoita kuti tambo yezvinhu zvetambo uye dhizaini dhizaini iite mutsauko wakakura wemitengo uye mutengo wakakura. Ehe, iyo inoenderana netambo performance zvakare inosiyana zvakanyanya. Pazasi pane kuparara kwemaitiro ezvimwe zvigadziriso zvetambo zvigadzirwa.
HDMI yakajairwa vhezheni
Waya yemhangura yekunze yakarukwa. Iwo maviri maviri akagadzirwa neMylar zvinhu uye aluminium foil layer.
Mukati wacho wakanyatsoputirwa nesimbi yekudzivirira chivharo kubva kumusoro kusvika pasi. Kana chivharo chesimbi chiri pamusoro chabviswa, pane yero yakakwirira-tembiricha yekunamatira tepi inovhara mukati. Nekubvisa chibatanidza, zvinogona kuonekwa kuti tambo imwe neimwe mukati yakabatanidzwa ne data data, iyo inozivikanwawo se "pini yakazara". Kunyanya, pamusoro pechigunwe chegoridhe chepamusoro chine dhizaini yegoridhe, uye mutsauko wemutengo wezvigadzirwa zvechokwadi uri mune izvi zvinhu.
Mazuva ano, kune zvakasiyana-siyana zveHDMI 2.1b cable zvakasiyana-siyana zvinosangana nemamiriro akasiyana ekushandiswa pamusika, zvakadai seSlim HDMI uye OD 3.0mm HDMI cables, iyo inonyanya kukodzera nzvimbo dzakabatanidzwa uye wiring yakavanzwa;
Right Angle HDMI (90-degree golbow) uye 90 L/T HDMI Cable, zviri nyore kubatanidza zvishandiso munzvimbo nhete;
MINI HDMI Cable (C-type) uye MICRO HDMI Cable (D-type), yakakodzera michina inotakurika yakadai semakamera uye mahwendefa;
Tambo dzepamusoro-soro dzakadai se8K HDMI, 48Gbps Spring HDMI, nezvimwewo, inovimbisa kugadzikana kwe-ultra-high bandwidth transmission;
Flexible HDMI uye Chitubu HDMI zvinhu zvine kuramba kwakanaka kwekukotama uye kusimba;
Iyo Slim 8K HDMI, MINI uye MICRO modhi ine simbi kesi shells inowedzera kuwedzera kudzivirira uye kusimba kweiyo interface, kunyanya yakakodzera kune yakakwirira-inopindira nharaunda kana maindasitiri maapplication.
Kana vatengi vachitenga, mukuwedzera pakuziva iyo yepamusoro-yekukurumidza HDMI certification label, ivo vanofanirwawo kusanganisa yavo yedhizaina yemhando yemhando (senge mini HDMI kuHDMI kana micro HDMI kuHDMI inodiwa) uye mamiriro ekushandisa (akadai sekuti kona yekurudyi kana dhizaini inodiwa) kusarudza yakanyatsokodzera HDMI 2.1b tambo kuti ive nechokwadi chekushanda kwakanyanya uye tambo.
