Ongororo yehunyanzvi yeHDMI 2.1b Specification
Kune vanoda maaudio nemavhidhiyo, michina inozivikanwa zvikuru ndeye HDMI cables uye interfaces. Kubva pakaburitswa 1.0 version yeHDMI specification muna 2002, yave nemakore anopfuura makumi maviri. Mumakore anopfuura makumi maviri apfuura, HDMI yave ndiyo standard interface inoshandiswa zvakanyanya mumidziyo yeaudio nemavhidhiyo. Sekureva kwezvinyorwa zvepamutemo, huwandu hwemidziyo yeHDMI yasvika mabhiriyoni gumi nerimwe, iyo yakaenzana nemidziyo yeHDMI inosvika miviri pamunhu pasi rose. Chinhu chikuru cheHDMI ndechekuti yakaenzana ne standard yayo. Mumakore makumi maviri apfuura, saizi ye physical ye standard HDMI interface yakaramba isina kuchinja, uye software protocol yakawana compatibility yakakwana yekudzokera shure. Izvi zvinonyanya kukodzera midziyo mikuru yemumba ine hardware updates inononoka, kunyanya materevhizheni. Kunyangwe kana TV iri kumba iri modhi yekare kubva makore anopfuura gumi apfuura, inogona kubatanidzwa zvakananga kuma consoles emitambo echizvarwa chinotevera pasina kuda ma adapter. Saka, mumakore achangopfuura, HDMI yakakurumidza kutsiva vhidhiyo, AV, audio, nezvimwe interfaces paterevhizheni uye yave interface yakajairika paterevhizheni. Zvichienderana nehuwandu, zvigadzirwa zvese zveterevhizheni zviri pamusika muna 2024 zvinoshandisa tekinoroji yeHDMI, uye HDMI yavewo kambani yakanakisa yemhando yepamusoro senge 4K, 8K, uye HDR. Mwero weHDMI 2.1a wakagadziridzwa zvakare: uchawedzera kugona kwemagetsi kutambo uye unoda kuiswa kwemachipisi mumidziyo yemagetsi.
HDMI® Specification 2.1b ndiyo vhezheni yazvino yeHDMI® Specification, inotsigira akasiyana-siyana maresolution evhidhiyo akakwira uye refresh rates, anosanganisira 8K60 ne4K120, pamwe nemaresolution anosvika 10K. Inotsigirawo mafomati e dynamic HDR, ine bandwidth capacity inowedzera kusvika ku48Gbps HDMI. Matambo matsva eUltra High Speed HDMI anotsigira bandwidth ye48Gbps. Matambo aya anovimbisa kupa maficha e ultra-high bandwidth independent, anosanganisira uncompressed 8K video ne HDR support. Ane ultra-low EMI (electromagnetic interference), anoderedza kukanganiswa nemidziyo isina waya iri pedyo. Matambo aya anoenderana nekumashure uye anogonawo kushandiswa nemidziyo yeHDMI iripo.
Zvinhu zviri muHDMI 2.1b zvinosanganisira:
Kukwanisa kwevhidhiyo kwakakwira: Inogona kutsigira akasiyana-siyana ma resolutions akakwira uye nekukurumidza kugadziridza (kusanganisira 8K60Hz uye 4K120Hz), ichipa ruzivo rwekuona rwakadzikama uye ruzivo rwakanaka rwekufamba nekukurumidza. Inotsigira resolution inosvika 10K, ichizadzisa zvinodiwa neAV yebhizinesi, maindasitiri, uye maapplication ehunyanzvi.
Dynamic HDR inoita kuti chiitiko chega chega uye kunyange furemu yega yega yevhidhiyo iratidze hunhu hwakakodzera hwekudzika, ruzivo rwakadzama, kupenya, kusiyana, uye ruvara rwakafara.
Kugadzira mapikicha emhando ye source-based tone mapping (SBTM) chinhu chitsva cheHDR. Kunze kwekushandisa HDR mapping inopedzwa ne display device, inogonesawo source device kuita chikamu che HDR mapping. SBTM inonyanya kubatsira pakubatanidza mavhidhiyo eHDR neSDR kana mifananidzo mumufananidzo mumwe chete, senge mifananidzo-mu-mufananidzo kana mapurogiramu epurogiramu ane mahwindo evhidhiyo akabatanidzwa. SBTM inobvumirawo PC nemidziyo yemitambo kugadzira otomatiki masaini eHDR akagadziridzwa kuti ishandise HDR kugona kwe display pasina kudikanwa kwekugadzirisa nemaoko mudziyo we source.
Tambo dzeHDMI dzinomhanya zvakanyanya dzinogona kutsigira basa reHDMI 2.1b risina kudzvanywa uye bandwidth ye48G yarinotsigira. EMI inoburitswa kubva patambo yakaderera zvikuru. Dzinoshandawo kumashure neshanduro dzekare dzeHDMI standard uye dzinogona kushandiswa nemidziyo yeHDMI iripo.
Chinongedzo cheHDMI 2.1b chinotsiva 2.0b, nepo chinongedzo che2.1a chichiramba chichireva uye chichivimba nechinongedzo cheHDMI 1.4b. HDMI®
Nzira yekuziva zvigadzirwa zveHDMI 2.1b
Matanho eHDMI 2.1b anosanganisira tambo itsva - Ultra High-Speed HDMI® Cable. Ndiyo chete tambo inotevedzera zvirevo zvakasimba, ichivavarira kuona kuti mabasa ese eHDMI 2.1b anotsigirwa, kusanganisira 8k@60 uye 4K@120 asina kudzvanywa. Kukwanisa kwakawedzerwa kwebandwidth yetambo iyi kunotsigira kusvika ku48Gbps. Matambo ese ane certification ekureba chero kupi anofanirwa kupasa bvunzo dzecertification dzeHDMI Forum Authorized Testing Center (Forum ATC). Kana yangobvumidzwa, tambo yacho inofanira kunge yakanamirwa papakeji yega yega kana unit yekutengesa, kuitira kuti vatengi vagone kuona mamiriro ecertification yechigadzirwa. Kuti uone tambo, iva nechokwadi chekuti label yecertification yeUltra High-Speed HDMI inodiwa sezvakaratidzwa pamusoro apa yaratidzwa papakeji. Ziva kuti logo yezita retambo yakadhindwa palabel. Zita iri rinofanirawo kuoneka pasheya yekunze yetambo. Kuti uone kana tambo yakaedzwa uye yakasimbiswa uye inoenderana nezvinodiwa neHDMI 2.1b, unogona kuskena kodhi yeQR pane label uchishandisa application yekubvumidza tambo yeHDMI inowanikwa muApple App Store, Google Play Store, nedzimwe nzvimbo dzekushandisa Android.
Waya yedhijitari yeHDMI 2.1b ine waya dzakakombama shanu mukati mewaya, ine ruvara rwekunze rwuri yero, orenji, chena, tsvuku, uye kune mapoka maviri ekubatanidza waya 6, zvichiita kuti waya 21 dzikwane. Parizvino, mhando yewaya dzeHDMI inosiyana zvikuru uye pane misiyano yakakura. Kusarongeka kwacho hakuna fungidziro. Vamwe vagadziri vanogona kugadzira zvigadzirwa zve3-meter zvakapedzwa newaya dze30AWG dzinosangana neEMI standards uye dzine bandwidth ye18G, nepo dzimwe waya dzakaburitswa nevagadziri dzine bandwidth ye13.5G chete, dzimwe dzine bandwidth ye10.2G chete, uye dzimwe dzine bandwidth ye5G chete. Nerombo rakanaka, HDMI Association ine zvirevo zvakadzama, uye nekuenzanisa, munhu anogona kuona mhando yewaya. Tsananguro yechimiro chewaya yetambo iripo: waya yealuminium foil iri mupakeji ye5P inoshandiswa kutumira data uye boka rimwe remasaini eDDC ekutaurirana. Mabasa ewaya dzemhangura nomwe ndeanoti: imwe yemagetsi, imwe yeCEC function, mbiri dzeaudio return (ARC), boka rimwe remasaini eDDC (waya mbiri dzepakati dzine furo uye imwe yevhu ine aluminium foil shielding) yekutaurirana. Sarudzo dzakasiyana dzezvinhu uye kusanganiswa kwebasa kunoita kuti chimiro chemidziyo yetambo uye dhizaini yekushanda kwayo zviite kuti pave nekusiyana kukuru kwemitengo uye mitengo yakakura. Ehe, mashandiro etambo anoenderana anosiyanawo zvikuru. Pazasi pane kuora kwechimiro chezvimwe zvigadzirwa zvetambo zvine hunyanzvi.
HDMI yakajairika
Waya yemhangura yekunze yakarukwa. Peya imwe chete yakagadzirwa nezvinhu zveMylar uye jira realuminium foil.
Mukati mayo makaputirwa zvakasimba nesimbi inovhara kubva kumusoro kusvika pasi. Kana chifukidziro chesimbi chiri pamusoro chabviswa, pane tepi yero inonamira inodziya zvakanyanya inofukidza mukati. Nekubvisa chinongedzo, zvinoonekwa kuti waya yega yega iri mukati yakabatana netambo yedata, inozivikanwawo se "full pins". Kunyanya, pamusoro pechigunwe chegoridhe pane jira regoridhe, uye musiyano wemitengo wezvigadzirwa zvechokwadi uri muzvinhu izvi.
Mazuva ano, kune mhando dzakasiyana dzetambo dzeHDMI 2.1b dzinoenderana nemamiriro akasiyana ekushandiswa pamusika, dzakadai seSlim HDMI neOD 3.0mm HDMI cables, dzakakodzera nzvimbo dzakamanikana uye waya dzakavanzwa;
HDMI yeAngle Yekurudyi (90-degree gokora) uye 90 L/T HDMI Cable, zviri nyore kubatanidza zvishandiso munzvimbo dzakamanikana;
Cable yeMINI HDMI (C-type) uye Cable yeMICRO HDMI (D-type), yakakodzera midziyo inotakurika yakaita semakamera nemapiritsi;
Tambo dzinoshanda zvakanyanya dzakadai se8K HDMI, 48Gbps Spring HDMI, nezvimwewo, dzinoita kuti bandwidth transmission irambe yakasimba;
Zvishandiso zveHDMI zvinochinjika uye zveSpring HDMI zvine simba rakanaka pakukombama uye kugara kwenguva refu;
Mamodheru eSlim 8K HDMI, MINI uye MICRO ane magoko esimbi anowedzera kuchengetedza uye kugara kwenguva refu kweinterface, kunyanya yakakodzera nzvimbo dzinokanganisa zvakanyanya kana mashandisirwo emaindasitiri.
Kana vatengi vakatenga, pamusoro pekuziva label yekusimbisa HDMI inokurumidza, vanofanirawo kusanganisa rudzi rwechishandiso chavo (sekuti kana HDMI diki kuenda kuHDMI kana micro HDMI kuenda kuHDMI ichidikanwa here) uye mamiriro ekushandisa (sekuti kana angle yekurudyi kana dhizaini diki ichidiwa) kuti vasarudze tambo yeHDMI 2.1b yakakodzera kwazvo kuti ive nechokwadi chekuti inoshanda zvakanaka uye inoenderana.
