Impumelelo Ezintathu ze-HDMI 2.2 kwiSatifikethi se-ULTRA96

Impumelelo Ezintathu ze-HDMI 2.2 kwiSatifikethi se-ULTRA96

Iintambo ze-HDMI 2.2 maziphawulwe ngamagama athi “ULTRA96″, nto leyo ebonisa ukuba zixhasa i-bandwidth efikelela kwi-96Gbps.

Le lebheli iqinisekisa ukuba umthengi uthenga imveliso ehlangabezana neemfuno zakhe, njengoko intambo yangoku ye-HDMI 2.1 inomlinganiselo ophezulu we-48 Gbps kuphela. Iforam ye-HDMI iya kuvavanya ubude bentambo nganye ukuqinisekisa ukuba iyahambelana, kwaye ilebheli kufuneka incamathiselwe kwintambo.
I-HDMI 2.2 inokudlulisa umxholo ngesisombululo esiphezulu se-12K kwi-120 fps okanye i-16K kwi-60 fps kwizixhobo ezixhaswayo, kwaye ikwaxhasa iifomathi ezipheleleyo ezingenanto yokulahleka, ezifana nesisombululo se-HDMI se-8K kwi-60 fps / 4:4:4 kunye nesisombululo se-4K kwi-240 fps / 4:4:4, kunye nobunzulu bombala we-10-bit kunye ne-12-bit.
Ukongeza, i-HDMI 2.2 ixhotyiswe ngesici esitsha esibizwa ngokuba yiDelay Indication Protocol (LIP), esinokuphucula ulungelelwaniso lwe-audio-video. Oku kuya kuba luncedo ngakumbi kwiindlela ezintsonkothileyo zokumisela inkqubo kuquka izamkeli ze-audio-video okanye izithethi ezijikelezileyo.

Njengoko iForam yeHDMI ikhupha ngokusesikweni iinkcukacha ezipheleleyo ze-HDMI version 2.2, iintambo ezinxulumene nazo eziqinisekisiweyo kunye nezixhobo ezihambelanayo kulindeleke ukuba ziqaliswe kungekudala.
Ukutolikwa kweenkcukacha ze-HDMI 2.2 kunye nemingeni yovavanyo kunye nesiqinisekiso
Kwicandelo lokusasazwa kweaudio kunye nevidiyo yedijithali, i-HDMI (i-High-Definition Multimedia Interface) ibambe isikhundla esiphambili. Ngokwedatha ekhutshwe yi-HDMI Licensing Administrator (HDMI LA) kwinkomfa ye-CES 2025, inani lezixhobo ezixhasa i-HDMI lidlule kwiiyunithi ezingama-900 ezigidi ngo-2024, kwaye umthamo wokuthunyelwa uwonke ufikelele kwiiyunithi ezili-1.4 zeebhiliyoni. Njengoko iimfuno zemarike zezisombululo eziphezulu, amazinga aphezulu okuhlaziya, kunye namava anzulu aqhubeka enyuka, njengokwanda kweeTV zemidlalo zesizukulwana esilandelayo ezinezicelo ze-4K@240Hz kunye ne-AR/VR, iForam ye-HDMI ibhengeze ngokusesikweni iinkcukacha ze-HDMI 2.2. Oku kulandelayo kukutolikwa kwezinto ezintathu eziphambili zobuchwepheshe ze-HDMI 2.2. Izinto ezintathu eziphambili zobuchwepheshe ze-HDMI 2.2 Ngokwengxelo ekhutshwe yiForam ye-HDMI, ukuphuculwa kwe-HDMI 2.2 kugxile kakhulu kwimisebenzi emithathu ephambili, ejolise ekuhlangabezaneni neemfuno zophuhliso zobuchwepheshe bomsindo-nokubukwa kwiminyaka elishumi ezayo: 1. Ukuphinda kabini kwe-bandwidth: Ukuya kwi-96Gbps FRL technology. Eyona nto iphawulekayo kukuphinda kabini ngokuthe ngqo kwe-bandwidth ephezulu ukusuka kwi-HDMI 2.1's 48Gbps ukuya kwi-96Gbps. Olu tshintsho lufezekiswa ngetekhnoloji entsha ethi "Fixed Rate Link (FRL)". Olu nyuko olumangalisayo lwe-bandwidth luya kuvula amandla angaqhelekanga okuvakalayo nokubonakalayo, kuquka: (1) Ukuxhasa imifanekiso eneenkcukacha eziphezulu ngaphandle kokucinezela: Iyakwazi ukuxhasa ngokwendalo i-4K@240Hz, 8K HDMI@120Hz, kunye nezinye iifomathi zemifanekiso ezikumgangatho ophezulu kakhulu nezihlaziyayo. (2) Ukubhukisha indawo yexesha elizayo: Ngokusebenzisa itekhnoloji yoxinzelelo lwevidiyo (DSC), inokuxhasa iinkcukacha ezimangalisayo ezifana ne-8K HDMI@240Hz, 10K@120Hz, kwane-12K@120Hz. (3) Ukuhlangabezana nezicelo zobungcali nezezorhwebo: Ukubonelela ngesiseko esiqinileyo sezicelo ezifuna ukuhanjiswa kwedatha enkulu, njenge-AR/VR/MR, imifanekiso yezonyango, kunye neephaneli ezinkulu zedijithali. 2. Inkqubo entsha yeCable kunye neSatifikethi se-Ultra96 HDMI®; Ukuze ithwale ithrafikhi enkulu ukuya kuthi ga kwi-96Gbps, iinkcukacha ze-HDMI 2.2 ziquka "iCable ye-Ultra96 HDMI®" entsha. Le ntambo iya kuba yinxalenye yeNkqubo yeSatifikethi se-HDMI Ultra, oko kuthetha ukuba imodeli nganye eyahlukileyo kunye nobude bentambo (njengeSlim HDMI, i-OD 3.0mm HDMI, i-Right Angle HDMI) kufuneka ivavanywe ngokungqongqo kwaye iqinisekiswe ngaphambi kokuba ifumaneke ukuze ithengiswe. I-HDMI LA igxininise kwingqungquthela ukubaluleka kokuthobela ukuhanjiswa kweenkonzo, kubandakanya nokulwa iimveliso ezingagunyaziswanga nezingathobeliyo. Oku kuthetha ukuba isatifikethi esisemthethweni siya kuba sibaluleke ngakumbi kunangaphambili. Eli nyathelo liqinisekisa ukuba abathengi banokuthenga iimveliso ezihlangabezana neemfuno kwaye zinokuhamba ngokukhululekileyo kwimarike yehlabathi. 3. Umsindisi wokuvumelanisa isandi nomboniso: I-Latency Indication Protocol (LIP) ibangela ukuba intshukumo yemilebe ingahambelani nesandi, nto leyo ebuhlungu kakhulu kubasebenzisi abaninzi bemidlalo yasekhaya okanye kwiinkqubo zesandi nomboniso ezintsonkothileyo. Ingakumbi kwiimeko apho isignali idlula kwizixhobo ezininzi (ezifana ne-game console -> AVR -> TV) ngendlela "yokutsiba okuninzi", ingxaki yokulibaziseka iba nkulu ngakumbi. I-HDMI 2.2 yazisa i-Latency Indication Protocol entsha (LIP), evumela isixhobo somthombo kunye nesixhobo sokubonisa ukuba sikwazi ukunxibelelana ngeemeko zazo zokulibaziseka, ivumela inkqubo ukuba ivumelanise iaudio kunye nevidiyo ngobulumko nangokufanelekileyo, nto leyo ephucula kakhulu amava omsebenzisi. Uthelekiso lweenkcukacha ze-HDMI 1.4 vs 2.1 vs 2.2 Ukuze uqonde ngcono izinto ezintsha zobuchwepheshe ze-HDMI 2.2, le theyibhile yokuthelekisa ilandelayo iqulunqwe ngokukodwa:

Imingeni yoVavanyo kunye neSatifikethi se-HDMI 2.2 Ukukhutshwa kwe-HDMI 2.2 kuza kuzisa imingeni emitsha emininzi kumanqanaba ahlukeneyo:

1. Uvavanyo lweLayer Physical (PHY): Umngeni omkhulu usekwe kukuthembeka kwesignali (Signal Integrity). Nge-bandwidth ye-96 Gbps, i-bandwidth ephezulu kakhulu ibeka iimfuno ezingqongqo kakhulu kukuthembeka kwesignali. Ngexesha lenkqubo yovavanyo, sidinga izixhobo ezichanekileyo zokuhlalutya izalathisi eziphambili ezifana needayagram zamehlo, i-jitter, ilahleko yokufakwa, kunye ne-crosstalk ukuqinisekisa uzinzo lwesignali ngexesha lokudluliselwa ngesantya esiphezulu. Iintambo kunye nezihlanganisi: Iintambo ezintsha ze-Ultra96 (kubandakanya i-Flexible HDMI, i-MINI HDMI Cable, i-MICRO HDMI Cable) kufuneka zidlule kwimigangatho yovavanyo engqongqo ngakumbi, kwaye ukusebenza kwazo kumaza aphezulu kuya kuba yeyona nto iphambili kwisatifikethi. Iziko lovavanyo eligunyazisiweyo elisemthethweni (i-ATC) liya kusebenzisana ngokusondeleyo ne-HDMI Forum ukuseka isisombululo sovavanyo esipheleleyo.
2. Uvavanyo lweProtocol Layer (Protocol): Ubunzima bovavanyo lweprotocol bunyuke kakhulu. Ukuqinisekiswa kweprotocol ye-LIP: I-Delay Indication Protocol (LIP) luphawu olutsha olufuna izixhobo ezizodwa zovavanyo lweprotocol ukulinganisa iimeko ezahlukeneyo zesixhobo se-multi-hop kunye nokuqinisekisa ukuchaneka konxibelelwano lweprotocol phakathi kwemithombo, ii-relay, kunye nezixhobo zokubonisa. Iindidi zefomathi ezinkulu: I-HDMI 2.2 ixhasa indibaniselwano enkulu kakhulu yezisombululo, amazinga okuhlaziya, isampuli ye-chroma, kunye nobunzulu bombala. Ngexesha lovavanyo, kuyimfuneko ukuqinisekisa ukuba imveliso inokuthetha ngokuchanekileyo kwaye ibonise kwiindidi ezahlukeneyo (ezifana ne-144Hz HDMI, 8K HDMI), ngakumbi xa ucinezelo lwe-DSC luvuliwe, oluya kwandisa kakhulu ubunzima kunye nexesha lovavanyo.
Ukukhutshwa kwe-HDMI 2.2 Kuphawula Isiganeko Esibalulekileyo Kuphuhliso Lweteknoloji Yonxibelelwano Lwesandi Nokubonwayo. Asikuko nje ukwanda kwe-bandwidth, kodwa kukwamele ukuqala kwenkqubo entsha enokuhlangabezana namava asemgangathweni ophezulu kunye namava asebenzisanayo kwiminyaka elishumi ezayo. Nangona ukwamkelwa ngokubanzi kweemveliso ze-HDMI 2.2 kusekude, ukuhlaziywa kwetekhnoloji akukaze kume. Iintambo ze-Ultra96 (kuquka i-Slim HDMI, i-Right Angle HDMI, i-MICRO HDMI Cable) kulindeleke ukuba zingene kwimarike kwikota yesithathu okanye yesine ka-2025. Masikwamkele kunye ukufika kwexesha elitsha lomgangatho wemifanekiso ophezulu kakhulu nge-HDMI 2.2.
