Katatu Kubudirira kweHDMI 2.2 muULTRA96 Certification

HDMI 2.2 tambo dzinofanirwa kumakwa nemazwi ekuti "ULTRA96", izvo zvinoratidza kuti dzinotsigira bandwidth inosvika 96Gbps.

Ichi chinyorwa chinovimbisa kuti mutengi anotenga chigadzirwa chinosangana nezvavanoda, sezvo ikozvino HDMI 2.1 tambo ine bandwidth yakakura ye48 Gbps chete. Iyo HDMI Forum inoedza hurefu hwega hwega tambo kuti ive nechokwadi chekutevedzera, uye iyo label inofanirwa kunamirwa kune tambo.
HDMI 2.2 inokwanisa kufambisa zvirimo pakugadziriswa kukuru kwe12K pa120fps kana 16K pa60fps kumidziyo inotsigirwa, uye inotsigirawo asina kurasikirwa akazara-mavara mafomati, akadai se8K HDMI resolution pa60 fps / 4:4:4 uye 4K resolution pa240 fps / 4:4:4, ine 1-bit 10-bit kudzika uye kudzika kwe10-bit.
Pamusoro pezvo, HDMI 2.2 inoshongedzerwa nechinhu chitsva chinodaidzwa kuti Delay Indication Protocol (LIP), inogona kuvandudza kuwiriranisa kwevhidhiyo-vhidhiyo. Izvi zvichanyanya kubatsira kune zvakanyanya kuomarara masisitimu anosanganisira odhiyo-vhidhiyo vanogamuchira kana vakakomberedza vatauri.

Iine HDMI Forum ichiburitsa zviri pamutemo zvirevo zveHDMI vhezheni 2.2, tambo dzakasimbiswa dzakasimbiswa uye zvishandiso zvinoenderana zvinotarisirwa kutangwa munguva pfupi iri kutevera.
Dudziro yeHDMI 2.2 Zvinotsanangurwa uye Zvinetso zvekuedza uye Certification
Mumunda wedhijitari odhiyo uye vhidhiyo kutapurirana, HDMI (High-Definition Multimedia Interface) inobata chinzvimbo chinotungamira. Zvinoenderana nedhata yakaburitswa neHDMI Licensing Administrator (HDMI LA) pamusangano weCES 2025, huwandu hwemidziyo inotsigira HDMI yakapfuura mazana mapfumbamwe emamiriyoni emamiriyoni muna 900, uye huwandu hwehuwandu hwekutakura hwasvika mabhiriyoni zana nemazana mana. Sezvo misika inoda zvigadziriso zvepamusoro, mareti ekuzorodza akakwira, uye zviitiko zvinonyudza zviri kuramba zvichikwira, sekuzivikanwa kwechizvarwa chinotevera maTV emitambo ane 4K@240Hz uye AR/VR maapplication, HDMI Forum yakazivisa zviri pamutemo HDMI 2.2 yakatarwa. Izvi zvinotevera dudziro yeatatu epakati tekinoroji magadzirirwo eHDMI 2.2. Izvo zvitatu zvakakosha zvetekinoroji zvigadzirwa zveHDMI 2.2 Maererano nekuburitswa neHDMI Forum, kukwidziridzwa kweHDMI 2.2 kunonyanya kutarisisa mabasa matatu akakosha, nechinangwa chekuzadzisa zvinodiwa zvekusimudzira tekinoroji-inotaridzika mumakore gumi anotevera: 1. Bandwidth kaviri: Kuenda ku96Gbps FRL tekinoroji. Kukwidziridzwa kunonyanya kuzivikanwa ndiko kupetwa kaviri kweyepamusoro bandwidth kubva kuHDMI 2.1's 48Gbps kusvika 96Gbps. Kusvetuka uku kunowanikwa kuburikidza neitsva "Fixed Rate Link (FRL) tekinoroji". Uku kunoshamisa kwekuwedzera kwebhanwidth kuchavhura kusati kwamboitika kweaudio-kuona kugona, kusanganisira: (1) Kutsigira mifananidzo yakasarudzika pasina kudzvanywa: Inokwanisa kutsigira natively 4K@240Hz, 8K HDMI@120Hz, uye mamwe emhando yepamusoro-yepamusoro-yepamusoro-yepamusoro-mwero mafomati emifananidzo. (2) Kuchengetera nzvimbo yeramangwana: Kuburikidza nevhidhiyo compression tekinoroji (DSC), inogona kutsigira zvinokatyamadza zvakatemwa se8K HDMI@240Hz, 10K@120Hz, uye kunyange 12K@120Hz. (3) Kusangana kwehunyanzvi uye zvekutengesa zvikumbiro: Kupa hwaro hwakasimba hwezvikumbiro zvinoda kutumira data hombe, seAR/VR/MR, imaging yekurapa, uye mapaneru makuru edhijitari. 2. New Ultra96 HDMI® Cable uye Certification Chirongwa; Kutakura traffic yakakura inosvika 96Gbps, iyo HDMI 2.2 yakatarwa inosanganisira itsva "Ultra96 HDMI® Cable". Tambo iyi ichave chikamu cheHDMI Ultra Certification Chirongwa, zvichireva kuti imwe neimwe yakasiyana modhi uye kureba kwetambo (seSlim HDMI, OD 3.0mm HDMI, Right Angle HDMI) inofanirwa kuongororwa kwakasimba uye chitupa isati yawanikwa kutengeswa. HDMI LA yakasimbisa pamusangano kukosha kwekutevedzwa kweketani, kusanganisira kuparara kwezvinhu zvisingabvumirwi uye zvisingaenderani. Izvi zvinoreva kuti certification yepamutemo ichave yakakosha kupfuura nakare kose. Iyi nhanho inovimbisa kuti vatengi vanokwanisa kutenga zvigadzirwa zvinoenderana nezvinodiwa uye zvinogona kufamba zvakasununguka mumusika wepasi rose. 3. Muponesi weaudio-visual synchronization: The Latency Indication Protocol (LIP) inoita kuti kufamba kwemiromo kusaenderane neruzha, chinova chinotyisa kuvazhinji vedzimba dzemitambo kana kuti maodhiyo-visual system vashandisi. Kunyanya mumamiriro ezvinhu apo chiratidzo chinopfuura nepakati pemidziyo yakawanda (senge game console -> AVR -> TV) nenzira ye "multiple-hop", dambudziko rekunonoka rinotonyanya kuoma. HDMI 2.2 inounza brand-itsva Latency Indication Protocol (LIP), iyo inogonesa sosi mudziyo uye mudziyo wekuratidzira kutaurirana mamiriro avo ekunonoka, zvichibvumira sisitimu kuwiriranisa odhiyo nevhidhiyo zvine hungwaru uye zvine hungwaru, zvakanyanya kuvandudza ruzivo rwemushandisi. HDMI 1.4 vs 2.1 vs.

Matambudziko eHDMI 2.2 Kuedzwa uye Certification Kuburitswa kweHDMI 2.2 kuchaunza akati wandei matambudziko pamatanho akasiyana:

1. Physical Layer (PHY) Testing: Dambudziko rakanyanyisa riri muchiratidzo chekuvimbika (Chiratidzo cheKutendeseka). Iine bandwidth ye96 Gbps, iyo yekupedzisira-yepamusoro bandwidth inoisa zvisati zvamboitika zvakaomesesa zvinodiwa pachiratidzo chekuvimbika. Munguva yekuyedza, isu tinoda zvimwe chaizvo zviridzwa zvekuongorora zvakakosha zviratidzo senge dhayagiramu yeziso, jitter, kurasikirwa kwekuisa, uye crosstalk kuti ive nechokwadi chekugadzikana kwechiratidzo panguva yekumhanyisa-kumhanya. Matambo uye zvinobatanidza: Iwo matsva eUltra96 tambo (kusanganisira Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) inofanirwa kupfuura yakaomesesa kuyerwa zviyero, uye kuita kwavo pamafafitera epamusoro kuchave kutarisisa kwechitupa. Iyo yepamutemo mvumo yekuyedza nzvimbo (ATC) ichanyatso shanda pamwe neHDMI Foramu kuti igadzire yakakwana yekuyedza mhinduro.
2. Protocol Layer (Protocol) Testing: Kuoma kwekuongorora kweprotocol kwakawedzera zvakanyanya. LIP protocol verification: Iyo Delay Indication Protocol (LIP) chinhu chitsva chinoda hunyanzvi hwekuyedza zviridzwa kuteedzera akasiyana-siyana akawanda-hop mudziyo mamiriro uye kuona chokwadi chekutaura kweprotocol pakati pezvinobva, zvinodzosera, uye zvigadziriso zvekuratidzira. Musanganiswa wemafomati makuru: HDMI 2.2 inotsigira musanganiswa wakakura kwazvo wezvisarudzo, mitengo yekuvandudza, chroma sampling, uye kudzika kwemavara. Panguva yekuyedzwa, zvinodikanwa kuve nechokwadi chekuti chigadzirwa chinogona kutaurirana nemazvo uye kuratidza mumisanganiswa yakasiyana-siyana (senge 144Hz HDMI, 8K HDMI), kunyanya kana DSC compression yakagoneswa, iyo inowedzera zvakanyanya kuoma uye nguva yekuyedzwa.
Kuburitswa kweHDMI 2.2's Kunoratidza Chinhu Chinokosha muAudio-Visual Interface Technology Development. Haisi kungowedzera bandwidth, asi zvakare inomiririra kutanga kweiyo ecosystem itsva inogona kurarama nehupamhi hwepamusoro uye zvimwe zvinodyidzana zviitiko mumakore gumi anotevera. Kunyangwe kutorwa kwakapararira kweHDMI 2.2 zvigadzirwa kuchiri imwe nguva kure, iyo yekuvandudza tekinoroji haina kumbomira. Ultra96 cables (kusanganisira Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) inotarisirwa kupinda mumusika muchikamu chechitatu kana chechina chegore ra 2025. Ngatigamuchirei pamwe chete kusvika kwenguva itsva yemhando yepamusoro yemifananidzo yepamusoro neHDMI 2.2.
