Kupambana Kutatu kwa HDMI 2.2 mu ULTRA96 Certification

Kupambana Kutatu kwa HDMI 2.2 mu ULTRA96 Certification

Zingwe za HDMI 2.2 ziyenera kulembedwa mawu oti "ULTRA96", zomwe zikuwonetsa kuti zimathandizira bandwidth mpaka 96Gbps.

Chizindikirochi chimatsimikizira kuti wogula amagula chinthu chomwe chimakwaniritsa zofunikira zawo, monga chingwe cha HDMI 2.1 chamakono chili ndi bandwidth yaikulu ya 48 Gbps yokha. Msonkhano wa HDMI udzayesa kutalika kwa chingwe kuti zitsimikizire kuti zikutsatira, ndipo chizindikirocho chiyenera kuikidwa pa chingwe.
HDMI 2.2 imatha kutumiza zomwe zili pamlingo waukulu wa 12K pa 120 fps kapena 16K pa 60 fps kupita ku zida zothandizira, komanso imathandizira mawonekedwe osatayika amitundu yonse, monga 8K HDMI resolution pa 60 fps / 4: 4: 4 ndi 4K resolution pa 240 fps / 4: 4: 4, ndi kuya kwa 10-bit 12-bit ndi kuya kwa 12-bit.
Kuphatikiza apo, HDMI 2.2 ili ndi chinthu chatsopano chotchedwa Delay Indication Protocol (LIP), chomwe chingathandizire kulumikizana kwamavidiyo ndi makanema. Izi zitha kukhala zothandiza makamaka pamasinthidwe ovuta kwambiri kuphatikiza olandila mavidiyo kapena olankhula mozungulira.

Ndi HDMI Forum ikutulutsa mwalamulo zonse zamtundu wa HDMI 2.2, zingwe zovomerezeka zofananira ndi zida zofananira zikuyembekezeka kukhazikitsidwa posachedwa.
Kutanthauzira kwa HDMI 2.2 Mafotokozedwe ndi Zovuta Zakuyesa ndi Chitsimikizo
Pankhani yotumizira mauthenga a digito ndi makanema, HDMI (High-Definition Multimedia Interface) ili ndi udindo wotsogola. Malinga ndi zomwe zidatulutsidwa ndi HDMI Licensing Administrator (HDMI LA) pamsonkhano wa CES 2025, kuchuluka kwa zida zothandizira HDMI zidapitilira mayunitsi 900 miliyoni mu 2024, ndipo kuchuluka kwazinthu zonse zomwe zidatumizidwa zayandikira mayunitsi 1.4 biliyoni. Monga momwe msika ukufunira zisankho zapamwamba, mitengo yotsitsimula kwambiri, komanso zokumana nazo zambiri zikupitilira kukwera, monga kutchuka kwa ma TV am'badwo wotsatira omwe ali ndi 4K@240Hz ndi mapulogalamu a AR/VR, HDMI Forum yalengeza movomerezeka za HDMI 2.2. Zotsatirazi ndikutanthauzira kwazinthu zitatu zamakono zamakono za HDMI 2.2. Zida zitatu zamakono zamakono za HDMI 2.2 Malingana ndi kutulutsidwa ndi HDMI Forum, kukweza kwa HDMI 2.2 makamaka kumakhudza ntchito zitatu zazikuluzikulu, pofuna kukwaniritsa zosowa za chitukuko cha teknoloji yamakono m'zaka khumi zikubwerazi: 1. Bandwidth kuwirikiza kawiri: Kusunthira ku teknoloji ya 96Gbps FRL. Kusintha kochititsa chidwi kwambiri ndi kuwirikiza kwachindunji kwa bandwidth yayikulu kuchokera ku HDMI 2.1's 48Gbps mpaka 96Gbps. Kudumphaku kumatheka kudzera muukadaulo watsopano wa "Fixed Rate Link (FRL)". Kuwonjezeka kodabwitsa kwa bandiwifi kudzatsegula mawonekedwe omvera omwe anali asanakhalepo kale, kuphatikiza: (1) Kuthandizira zithunzi zodziwika bwino popanda kukanikizidwa: Kutha kuthandizira 4K@240Hz, 8K HDMI@120Hz, ndi mawonekedwe ena apamwamba kwambiri komanso otsitsimula kwambiri. (2) Kusunga malo amtsogolo: Kupyolera muukadaulo waukadaulo wamakanema (DSC), imatha kuthandizira modabwitsa monga 8K HDMI@240Hz, 10K@120Hz, komanso 12K@120Hz. (3) Kukumana ndi ntchito zamaluso ndi zamalonda: Kupereka maziko olimba a mapulogalamu omwe amafunikira kutumiza deta yayikulu, monga AR/VR/MR, kujambula kwachipatala, ndi mapanelo akulu a digito. 2. Pulogalamu Yatsopano ya Ultra96 HDMI® Cable ndi Certification; Kuti munyamule kuchuluka kwa magalimoto mpaka 96Gbps, mawonekedwe a HDMI 2.2 akuphatikizapo "Ultra96 HDMI® Cable" yatsopano. Chingwe ichi chidzakhala gawo la HDMI Ultra Certification Program, kutanthauza kuti mtundu uliwonse wosiyana ndi kutalika kwa chingwe (monga Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) ayenera kuyesedwa kotheratu ndi kutsimikiziridwa asanagulitsidwe. HDMI LA inagogomezera pamsonkhanowu kufunikira kwa kutsatiridwa kwa chain chain, kuphatikizapo kuwonongeka kwa zinthu zosaloleka komanso zosavomerezeka. Izi zikutanthauza kuti chiphaso chovomerezeka chikhala chofunikira kwambiri kuposa kale. Kusunthaku kumatsimikizira kuti ogula amatha kugula zinthu zomwe zimakwaniritsa zofunikira ndipo zimatha kuyenda momasuka pamsika wapadziko lonse lapansi. 3. Mpulumutsi wamalumikizidwe a audio-visual synchronization: The Latency Indication Protocol (LIP) imapangitsa kusuntha kwa milomo kusafanane ndi phokoso, zomwe zimakhala zoopsa kwa ambiri ogwiritsa ntchito zisudzo zapanyumba kapena makina ovuta a audio-visual system. Makamaka muzochitika zomwe chizindikirocho chimadutsa pazida zingapo (monga kontrakitala yamasewera -> AVR -> TV) munjira ya "multiple-hop", vuto lochedwa limakula kwambiri. HDMI 2.2 imabweretsa pulogalamu yatsopano ya Latency Indication Protocol (LIP), yomwe imathandizira chipangizo choyambira ndi chipangizo chowonetsera kuti chizitha kufotokozera momwe akuchedwera, kulola kuti dongosololi ligwirizanitse zomvera ndi makanema mwanzeru komanso mwaluso, kuwongolera kwambiri zomwe ogwiritsa ntchito akukumana nazo. HDMI 1.4 vs 2.1 vs 2.2 Kufananitsa Kwatsatanetsatane Kuti mumvetse bwino zaukadaulo wa HDMI 2.2, tebulo lofananizira lotsatirali lapangidwa mwapadera:

Zovuta za Kuyesa ndi Chitsimikizo cha HDMI 2.2 Kutulutsidwa kwa HDMI 2.2 kudzabweretsa zovuta zingapo zatsopano pamagawo osiyanasiyana:

1. Physical Layer (PHY) Kuyesa: Vuto lalikulu liri mu kukhulupirika kwa chizindikiro (Signal Integrity). Ndi bandwidth ya 96 Gbps, bandwidth yapamwamba kwambiri imayika zofunikira zomwe sizinachitikepo pa kukhulupirika kwa chizindikiro. Panthawi yoyesera, timafunikira zida zolondola kwambiri zowunikira zizindikiro zazikulu monga zojambula zamaso, jitter, kutayika kwa kuika, ndi crosstalk kuti zitsimikizire kukhazikika kwa chizindikiro panthawi yotumiza mofulumira. Zingwe ndi zolumikizira: Zingwe zatsopano za Ultra96 (kuphatikiza Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) ziyenera kudutsa miyezo yoyezetsa kwambiri, ndipo magwiridwe antchito ake pama frequency apamwamba ndiye cholinga cha certification. Malo ovomerezeka ovomerezeka ovomerezeka (ATC) adzagwirizana kwambiri ndi HDMI Forum kuti akhazikitse yankho lathunthu loyesa.
2. Mayeso a Protocol Layer (Protocol): Kuvuta kwa kuyesa kwa protocol kwawonjezeka kwambiri. Kutsimikizika kwa protocol ya LIP: Delay Indication Protocol (LIP) ndi chinthu chatsopano chomwe chimafunikira zida zapadera zoyezera ma protocol kuti ayesere zochitika zosiyanasiyana za zida zamitundu yambiri ndikuwonetsetsa kulondola kwa kulumikizana kwa protocol pakati pa magwero, ma relay, ndi zida zowonetsera. Kuphatikizika kwamitundu yayikulu: HDMI 2.2 imathandizira kuphatikiza kwakukulu kwamalingaliro, mitengo yotsitsimutsa, sampuli za chroma, ndi kuya kwamitundu. Pakuyesa, ndikofunikira kuwonetsetsa kuti mankhwalawa amatha kukambirana moyenera ndikuwonetsa pazophatikizira zosiyanasiyana (monga 144Hz HDMI, 8K HDMI), makamaka pamene kupsinjika kwa DSC kumathandizira, zomwe zidzakulitsa kwambiri zovuta komanso nthawi yoyesera.
Kutulutsidwa kwa HDMI 2.2's Kumawonetsa Mwala Wofunika Kwambiri pa Kukula kwaukadaulo wa Audio-Visual Interface. Sikungowonjezereka kwa bandwidth, komanso kuyimira chiyambi cha chilengedwe chatsopano chomwe chingathe kulimbana ndi khalidwe lapamwamba komanso zochitika zowonjezereka m'zaka khumi zikubwerazi. Ngakhale kufalikira kwa zinthu za HDMI 2.2 kudakali nthawi yayitali, kusinthika kwaukadaulo sikunayime. Zingwe za Ultra96 (kuphatikizapo Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) zikuyembekezeka kulowa msika mu gawo lachitatu kapena lachinayi la 2025. Tiyeni tilandire pamodzi kufika kwa nyengo yatsopano ya khalidwe lapamwamba kwambiri la zithunzi ndi HDMI 2.2.
