Kupambana Kutatu kwa HDMI 2.2 mu Chitsimikizo cha ULTRA96

Zingwe za HDMI 2.2 ziyenera kulembedwa ndi mawu akuti “ULTRA96″,” zomwe zikusonyeza kuti zimathandiza bandwidth yofika 96Gbps.

Chizindikiro ichi chimatsimikizira kuti wogula agula chinthu chomwe chikukwaniritsa zofunikira zake, popeza chingwe cha HDMI 2.1 chomwe chilipo chili ndi bandwidth yayikulu ya 48 Gbps yokha. HDMI Forum idzayesa kutalika kulikonse kwa chingwe kuti itsimikizire kuti chikugwirizana ndi zomwe zili, ndipo chizindikirocho chiyenera kumangiriridwa ku chingwecho.
HDMI 2.2 imatha kutumiza zomwe zili ndi resolution ya 12K pa 120 fps kapena 16K pa 60 fps kuzipangizo zothandizira, ndipo imathandiziranso mitundu yonse yamitundu yopanda kutayika, monga resolution ya 8K HDMI pa 60 fps / 4:4:4 ndi resolution ya 4K pa 240 fps / 4:4:4, yokhala ndi kuya kwa utoto wa 10-bit ndi 12-bit.
Kuphatikiza apo, HDMI 2.2 ili ndi chinthu chatsopano chotchedwa Delay Indication Protocol (LIP), chomwe chingathandize kusintha kulumikizana kwa mawu ndi kanema. Izi zidzakhala zothandiza makamaka pamakonzedwe ovuta kwambiri a makina kuphatikizapo zolandirira mawu ndi kanema kapena ma speaker ozungulira.

Popeza HDMI Forum yatulutsa mwalamulo zofunikira zonse za HDMI mtundu 2.2, zingwe zovomerezeka ndi zida zogwirizana nazo zikuyembekezeka kuyambitsidwa posachedwa.
Kutanthauzira kwa HDMI 2.2 Mafotokozedwe ndi Mavuto a Kuyesa ndi Chitsimikizo
Pankhani yofalitsa mawu ndi makanema pa digito, HDMI (High-Definition Multimedia Interface) ili ndi udindo wotsogola. Malinga ndi deta yomwe idatulutsidwa ndi HDMI Licensing Administrator (HDMI LA) pamsonkhano wa CES 2025, chiwerengero cha zipangizo zothandizira HDMI chinaposa mayunitsi 900 miliyoni mu 2024, ndipo kuchuluka kwa kutumiza konse kwafika pafupifupi mayunitsi 1.4 biliyoni. Pamene kufunikira kwa msika kwa ma resolution apamwamba, mitengo yotsitsimutsa kwambiri, komanso zokumana nazo zambiri zikupitirira kukwera, monga kufalikira kwa ma TV amasewera a m'badwo wotsatira okhala ndi mapulogalamu a 4K@240Hz ndi AR/VR, HDMI Forum yalengeza mwalamulo za HDMI 2.2 specification. Izi ndi kutanthauzira kwa zatsopano zitatu zazikulu zaukadaulo za HDMI 2.2. Zatsopano zitatu zazikulu zaukadaulo za HDMI 2.2 Malinga ndi zomwe zatulutsidwa ndi HDMI Forum, kukweza kwa HDMI 2.2 kumayang'ana kwambiri ntchito zitatu zazikulu, zomwe cholinga chake ndi kukwaniritsa zosowa za chitukuko cha ukadaulo wowonera mawu m'zaka khumi zikubwerazi: 1. Kuchulukitsa Bandwidth: Kupita ku ukadaulo wa 96Gbps FRL. Kusintha kodziwika bwino kwambiri ndi kuwirikiza kawiri kwa bandwidth yayikulu kwambiri kuchokera pa HDMI 2.1's 48Gbps mpaka 96Gbps. Kudumphaku kumachitika kudzera mu ukadaulo watsopano wa "Fixed Rate Link (FRL). Kuwonjezeka kodabwitsa kwa bandwidth kumeneku kudzatsegula luso losawoneka bwino la mawu ndi zithunzi, kuphatikiza: (1) Kuthandizira zithunzi zapamwamba popanda kukanikiza: Kutha kuthandizira 4K@240Hz, 8K HDMI@120Hz, ndi mitundu ina yazithunzi zapamwamba kwambiri komanso zotsitsimula kwambiri. (2) Kusunga malo mtsogolo: Kudzera muukadaulo wa compression wamavidiyo (DSC), imatha kuthandizira ma specification odabwitsa monga 8K HDMI@240Hz, 10K@120Hz, komanso 12K@120Hz. (3) Kukwaniritsa ntchito zaukadaulo ndi zamalonda: Kupereka maziko olimba a mapulogalamu omwe amafunikira kutumiza deta yayikulu, monga AR/VR/MR, kujambula zamankhwala, ndi mapanelo akuluakulu a digito. 2. Pulogalamu Yatsopano ya Chingwe ndi Chitsimikizo cha Ultra96 HDMI®; Kuti zinyamule magalimoto ambiri okwana 96Gbps, HDMI 2.2 ikuphatikizapo "Chingwe cha Ultra96 HDMI®" chatsopano. Chingwechi chidzakhala gawo la Pulogalamu Yotsimikizira ya HDMI Ultra, zomwe zikutanthauza kuti mtundu uliwonse wosiyana ndi kutalika kwa chingwe (monga Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) ziyenera kuyesedwa mwamphamvu ndi kutsimikiziridwa zisanagulitsidwe. HDMI LA idagogomezera pamsonkhanowo kufunika kotsatira malamulo a unyolo wogulira, kuphatikizapo kuletsa zinthu zosaloledwa komanso zosatsatira malamulo. Izi zikutanthauza kuti chitsimikizo chovomerezeka chidzakhala chofunikira kwambiri kuposa kale lonse. Izi zimatsimikizira kuti ogula amatha kugula zinthu zomwe zikugwirizana ndi zofunikira ndipo zimatha kuyenda momasuka pamsika wapadziko lonse lapansi. 3. Mpulumutsi wa kulumikizana kwa mawu ndi zithunzi: Latency Indication Protocol (LIP) imapangitsa kuti milomo isagwirizane ndi mawu, zomwe ndi zovuta kwa ogwiritsa ntchito ambiri owonera kunyumba kapena makina ovuta a mawu ndi zithunzi. Makamaka m'malo omwe chizindikiro chimadutsa pazida zingapo (monga console yamasewera -> AVR -> TV) mwanjira ya "multiple-hop", vuto lochedwa limakhala lalikulu kwambiri. HDMI 2.2 imabweretsa Latency Indication Protocol yatsopano (LIP), yomwe imalola chipangizo choyambira ndi chipangizo chowonetsera kuti chizilankhulana ndi momwe zinthu zikuchedwera, zomwe zimathandiza kuti dongosololi ligwirizanitse mawu ndi makanema mwanzeru komanso moyenera, zomwe zimapangitsa kuti ogwiritsa ntchito azisangalala kwambiri. HDMI 1.4 vs 2.1 vs 2.2 Kuyerekeza Mafotokozedwe Kuti mumvetse bwino zaukadaulo wa HDMI 2.2, tebulo loyerekeza lotsatirali lapangidwa mwapadera:

Mavuto a Kuyesa ndi Kupereka Chitsimikizo cha HDMI 2.2 Kutulutsidwa kwa HDMI 2.2 kudzabweretsa mavuto atsopano angapo pamlingo wosiyana:

1. Kuyesa kwa Physical Layer (PHY): Vuto lalikulu lili pa kukhulupirika kwa chizindikiro (Signal Integrity). Ndi bandwidth ya 96 Gbps, bandwidth yapamwamba kwambiri imapanga zofunikira kwambiri pa kukhulupirika kwa chizindikiro. Panthawi yoyesera, tikufunika zida zolondola kwambiri kuti tiwunike zizindikiro zazikulu monga ma diagram a maso, jitter, insertion loss, ndi crosstalk kuti tiwonetsetse kuti chizindikirocho chili chokhazikika panthawi yotumiza mwachangu. Zingwe ndi zolumikizira: Zingwe zatsopano za Ultra96 (kuphatikiza Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) ziyenera kudutsa miyezo yoyesera yokhwima kwambiri, ndipo magwiridwe antchito awo pama frequency apamwamba adzakhala cholinga cha satifiketi. Malo oyesera ovomerezeka (ATC) adzagwirizana kwambiri ndi HDMI Forum kuti akhazikitse yankho lathunthu loyesera.
2. Kuyesa kwa Protocol Layer (Protocol): Kuvuta kwa kuyesa kwa protocol kwawonjezeka kwambiri. Kutsimikizira kwa protocol ya LIP: Protocol ya Delay Indication (LIP) ndi chinthu chatsopano chomwe chimafuna zida zapadera zoyesera protocol kuti zitsanzire zochitika zosiyanasiyana za chipangizo cha multi-hop ndikutsimikizira kulondola kwa kulumikizana kwa protocol pakati pa magwero, ma relay, ndi zida zowonetsera. Kuphatikiza kwakukulu kwa mawonekedwe: HDMI 2.2 imathandizira kuphatikiza kwakukulu kwa ma resolution, kuchuluka kwa zotsitsimutsa, chroma sampling, ndi kuya kwa mitundu. Pakuyesa, ndikofunikira kuonetsetsa kuti chinthucho chikhoza kukambirana bwino ndikuwonetsa m'mitundu yosiyanasiyana (monga 144Hz HDMI, 8K HDMI), makamaka pamene kukanikiza kwa DSC kwayatsidwa, zomwe zidzawonjezera kwambiri zovuta ndi nthawi yoyesera.
Kutulutsidwa kwa HDMI 2.2 Kukuwonetsani Chitukuko Chofunika Kwambiri pa Kukonza Ukadaulo wa Audio-Visual Interface. Sikuti kungowonjezera kuchuluka kwa bandwidth, komanso kukuyimira chiyambi cha njira yatsopano yolumikizirana ndi zinthu zapamwamba komanso zokumana nazo zambiri m'zaka khumi zikubwerazi. Ngakhale kuti kugwiritsa ntchito zinthu za HDMI 2.2 kudakali kutali, kusintha kwa ukadaulo sikunayime. Zingwe za Ultra96 (kuphatikiza Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) zikuyembekezeka kulowa pamsika mu kotala lachitatu kapena lachinayi la 2025. Tiyeni tilandire limodzi kufika kwa nthawi yatsopano ya chithunzi chapamwamba kwambiri ndi HDMI 2.2.
