Ukuthuthukiswa Okuthathu kwe-HDMI 2.2 ku-ULTRA96 Certification

Ukuthuthukiswa Okuthathu kwe-HDMI 2.2 ku-ULTRA96 Certification

Izintambo ze-HDMI 2.2 kumele zimakwe ngamagama athi “ULTRA96″, okubonisa ukuthi zisekela i-bandwidth efinyelela ku-96Gbps.

Le lebula iqinisekisa ukuthi umthengi uthenga umkhiqizo ohlangabezana nezidingo zakhe, njengoba ikhebula lamanje le-HDMI 2.1 linomkhawulokudonsa ophezulu ongu-48 Gbps kuphela. Iforamu ye-HDMI izohlola ubude bekhebula ngalinye ukuqinisekisa ukuhambisana, futhi ilebula kumele linamathiselwe kukhebula.
I-HDMI 2.2 ingadlulisela okuqukethwe ngesisombululo esiphezulu se-12K ku-120 fps noma i-16K ku-60 fps kumadivayisi asekelwayo, futhi isekela namafomethi agcwele angenakulahlekelwa, njengesisombululo se-HDMI esingu-8K ku-60 fps / 4:4:4 kanye nesinqumo se-4K ku-240 fps / 4:4:4, ngobubanzi bombala obungu-10-bit kanye no-12-bit.
Ngaphezu kwalokho, i-HDMI 2.2 ifakwe isici esisha esibizwa ngokuthi i-Delay Indication Protocol (LIP), esingathuthukisa ukuvumelanisa umsindo nevidiyo. Lokhu kuzoba usizo ikakhulukazi ekucushweni kwesistimu okuyinkimbinkimbi okuhlanganisa izamukeli zomsindo nevidiyo noma izipikha ezizungezile.

Njengoba i-HDMI Forum ikhipha ngokusemthethweni imininingwane ephelele ye-HDMI version 2.2, izintambo eziqinisekisiwe ezihlobene namadivayisi ahambisanayo kulindeleke ukuthi zethulwe maduze.
Ukuhunyushwa Kwezincazelo ze-HDMI 2.2 kanye Nezinselele Zokuhlola Nokuqinisekisa
Emkhakheni wokudlulisa umsindo nevidiyo yedijithali, i-HDMI (High-Definition Multimedia Interface) iphethe isikhundla esiphambili. Ngokusho kwedatha ekhishwe yi-HDMI Licensing Administrator (HDMI LA) engqungqutheleni ye-CES 2025, inani lamadivayisi asekela i-HDMI lidlule amayunithi ayizigidi ezingu-900 ngo-2024, kanti inani eliphelele lokuthunyelwa selifinyelele kumayunithi ayizigidi eziyi-1.4. Njengoba izidingo zemakethe zezinqumo eziphakeme, amazinga aphezulu okuvuselela, kanye nokuhlangenwe nakho okujulile kuqhubeka nokukhula, njengokwanda kwama-TV okudlala esizukulwane esilandelayo anezinhlelo zokusebenza ze-4K@240Hz kanye ne-AR/VR, i-HDMI Forum imemezele ngokusemthethweni imininingwane ye-HDMI 2.2. Okulandelayo ukuhunyushwa kwezinto ezintathu zobuchwepheshe eziyinhloko ze-HDMI 2.2. Izinto ezintathu zobuchwepheshe eziyinhloko ze-HDMI 2.2 Ngokusho kokukhishwa yi-HDMI Forum, ukuthuthukiswa kwe-HDMI 2.2 kugxile kakhulu emisebenzini emithathu eyinhloko, okuhlose ukuhlangabezana nezidingo zokuthuthukiswa kobuchwepheshe bomsindo nokubukwayo eminyakeni eyishumi ezayo: 1. Ukuphindaphinda kwe-bandwidth: Ukuqhubekela phambili kubuchwepheshe be-FRL obuyi-96Gbps. Ukuthuthukiswa okuphawuleka kakhulu ukuphindaphindwa okuqondile kwe-bandwidth ephezulu kusuka ku-HDMI 2.1's 48Gbps kuya ku-96Gbps. Lokhu kukhuphuka kufezwa ngobuchwepheshe obusha be-“Fixed Rate Link (FRL)”. Lokhu kwanda kwe-bandwidth okumangalisayo kuzovula amakhono angakaze abonwe ngaphambili omsindo nokubukwayo, okuhlanganisa: (1) Ukusekela izithombe ezicacisiwe kakhulu ngaphandle kokucindezelwa: Iyakwazi ukusekela ngokwemvelo i-4K@240Hz, i-8K HDMI@120Hz, kanye nezinye izinhlobo zezithombe ezisezingeni eliphezulu kakhulu neziqabulayo. (2) Ukubhukha isikhala sesikhathi esizayo: Ngobuchwepheshe bokucindezela ividiyo (i-DSC), ingasekela izici ezimangalisayo njenge-8K HDMI@240Hz, 10K@120Hz, ngisho ne-12K@120Hz. (3) Ukuhlangabezana nezinhlelo zokusebenza zobungcweti nezentengiselwano: Ukuhlinzeka ngesisekelo esiqinile sezinhlelo zokusebenza ezidinga ukudluliswa kwedatha enkulu, njenge-AR/VR/MR, izithombe zezokwelapha, kanye namaphaneli amakhulu edijithali. 2. Uhlelo Olusha Lwekhebula Nesitifiketi se-Ultra96 HDMI®; Ukuze kuthwalwe ithrafikhi enkulu efinyelela ku-96Gbps, imininingwane ye-HDMI 2.2 ifaka phakathi i-“Ultra96 HDMI® Cable” entsha. Le khebula izoba yingxenye yoHlelo Lokuqinisekisa lwe-HDMI Ultra, okusho ukuthi imodeli ngayinye ehlukile nobude bekhebula (njenge-Slim HDMI, i-OD 3.0mm HDMI, i-Right Angle HDMI) kumele ihlolwe futhi iqinisekiswe ngaphambi kokuba itholakale ukuze ithengiswe. I-HDMI LA igcizelele engqungqutheleni ukubaluleka kokuhambisana nochungechunge lokuhlinzekwa, okuhlanganisa nokucindezelwa kwemikhiqizo engagunyaziwe nengahambisani nayo. Lokhu kusho ukuthi isitifiketi esisemthethweni sizoba sibaluleke kakhulu kunanini ngaphambili. Lesi sinyathelo siqinisekisa ukuthi abathengi bangathenga imikhiqizo ehlangabezana nezimfuneko futhi engahamba ngokukhululeka emakethe yomhlaba wonke. 3. Umsindisi wokuvumelanisa umsindo nokubukwayo: I-Latency Indication Protocol (LIP) ibangela ukunyakaza kwezindebe kungafani nomsindo, okuyiphupho elibi kakhulu kubasebenzisi abaningi bemidlalo yaseshashalazini yasekhaya noma abasebenzisi besistimu yomsindo nokubukwayo eyinkimbinkimbi. Ikakhulukazi ezimweni lapho isignali idlula kumadivayisi amaningi (njenge-game console -> AVR -> TV) ngendlela "yokugxuma okuningi", inkinga yokulibaziseka iba nkulu kakhulu. I-HDMI 2.2 yethula i-Latency Indication Protocol entsha sha (LIP), evumela idivayisi yomthombo kanye nedivayisi yokubonisa ukuthi ixhumane nezimo zayo zokulibaziseka, okuvumela uhlelo ukuthi luvumelanise umsindo nevidiyo ngokuhlakanipha nangendlela ephumelelayo, okuthuthukisa kakhulu ulwazi lomsebenzisi. Ukuqhathanisa Imininingwane ye-HDMI 1.4 vs 2.1 vs 2.2 Ukuze uqonde kangcono ubuchwepheshe be-HDMI 2.2, ithebula lokuqhathanisa elilandelayo lihlanganiswe ngokukhethekile:

Izinselele Zokuhlolwa Nokuqinisekiswa kwe-HDMI 2.2 Ukukhishwa kwe-HDMI 2.2 kuzoletha izinselele eziningana ezintsha emazingeni ahlukene:

1. Ukuhlolwa Kwezingqimba Eziphathekayo (PHY): Inselele enkulu isekuthembekeni kwesignali (Ubuqotho Besignali). Ngobubanzi be-bandwidth obungu-96 Gbps, ububanzi be-bandwidth obuphezulu kakhulu bubeka izidingo eziqinile kakhulu ekuthembekeni kwesignali. Ngesikhathi senqubo yokuhlola, sidinga amathuluzi anembe kakhulu ukuhlaziya izinkomba ezibalulekile njengemidwebo yamehlo, i-jitter, ukulahlekelwa kokufakwa, kanye nokukhuluma okuphambene ukuqinisekisa ukuzinza kwesignali ngesikhathi sokudlulisa ngesivinini esikhulu. Izintambo nezixhumi: Izintambo ezintsha ze-Ultra96 (kufaka phakathi i-Flexible HDMI, i-MINI HDMI Cable, i-MICRO HDMI Cable) kumele zidlule amazinga okuhlola aqinile, futhi ukusebenza kwazo kumaza aphezulu kuzoba yinto ebalulekile yesitifiketi. Isikhungo sokuhlola esigunyaziwe esisemthethweni (i-ATC) sizobambisana eduze ne-HDMI Forum ukuze sisungule ikhambi lokuhlola eliphelele.
2. Ukuhlolwa Kwe-Protocol Layer (Protocol): Ubunzima bokuhlolwa kwe-protocol bukhule kakhulu. Ukuqinisekiswa kwe-LIP protocol: I-Delay Indication Protocol (LIP) iyisici esisha esidinga amathuluzi okuhlola i-protocol akhethekile ukuze kulingiswe izimo ezahlukene zamadivayisi e-multi-hop futhi kuqinisekiswe ukunemba kokuxhumana kwe-protocol phakathi kwemithombo, ama-relay, namadivayisi okubonisa. Ukuhlanganiswa okukhulu kwefomethi: I-HDMI 2.2 isekela inhlanganisela enkulu kakhulu yezinqumo, amazinga okuvuselela, isampula ye-chroma, kanye nokujula kombala. Ngesikhathi sokuhlola, kubalulekile ukuqinisekisa ukuthi umkhiqizo ungaxoxisana kahle futhi uboniswe ezinhlanganisweni ezahlukene (njenge-144Hz HDMI, i-8K HDMI), ikakhulukazi lapho kuvunyelwe ukucindezelwa kwe-DSC, okuzokwandisa kakhulu ubunzima nesikhathi sokuhlola.
Ukukhishwa kwe-HDMI 2.2 Kuphawula Ingqophamlando Ebalulekile Ekuthuthukisweni Kobuchwepheshe Be-Audio-Visual Interface. Akukona nje ukwanda kwe-bandwidth, kodwa futhi kumelela ukuqala kwendalo entsha engabhekana nekhwalithi ephezulu kanye nokuhlangenwe nakho okusebenzisana kakhulu eminyakeni eyishumi ezayo. Nakuba ukwamukelwa kabanzi kwemikhiqizo ye-HDMI 2.2 kusesekude, ukuvuselelwa kobuchwepheshe akukaze kume. Izintambo ze-Ultra96 (kufaka phakathi i-Slim HDMI, i-Right Angle HDMI, i-MICRO HDMI Cable) kulindeleke ukuthi zingene emakethe kwikota yesithathu noma yesine ka-2025. Masikwamukele ngokubambisana ukufika kwenkathi entsha yekhwalithi yesithombe ephezulu kakhulu nge-HDMI 2.2.
