Ukuphumelela Okuthathu kwe-HDMI 2.2 kusitifiketi se-ULTRA96

Ukuphumelela Okuthathu kwe-HDMI 2.2 kusitifiketi se-ULTRA96

Izintambo ze-HDMI 2.2 kufanele zimakwe ngamagama athi “ULTRA96″, okubonisa ukuthi asekela umkhawulokudonsa ongafika ku-96Gbps.

Le lebula iqinisekisa ukuthi umthengi uthenga umkhiqizo ohlangabezana nezidingo zabo, njengoba ikhebula le-HDMI 2.1 lamanje linomkhawulokudonsa ongu-48 Gbps kuphela. Iforamu ye-HDMI izohlola ubude bekhebula ngabunye ukuze kuqinisekiswe ukuthobela umthetho, futhi ilebula kufanele inamathiselwe kukhebula.
I-HDMI 2.2 ingadlulisela okuqukethwe ngokulungiswa okuphezulu okungu-12K ku-120 fps noma i-16K ku-60 fps kumadivayisi asekelwayo, futhi futhi isekela amafomethi angalahleki anombala ogcwele, njengesixazululo se-8K HDMI ku-60 fps / 4:4:4 kanye nokulungiswa kwe-4K ku-240 fps / 4:4:4, enombala ongu-10-bit nokujula kwe-12-bit.
Ngaphezu kwalokho, i-HDMI 2.2 ifakwe isici esisha esibizwa ngokuthi i-Delay Indication Protocol (LIP), engathuthukisa ukuvumelanisa okulalelwayo nevidiyo. Lokhu kuzoba usizo ikakhulukazi ekucushweni kwesistimu okuyinkimbinkimbi okuhlanganisa izamukeli zomsindo nevidiyo noma izipikha ezizungezile.

Njengoba i-HDMI Forum ikhulula ngokusemthethweni ukucaciswa okuphelele kwenguqulo ye-HDMI engu-2.2, izintambo eziqinisekisiwe ezihlobene namadivayisi ahambisanayo kulindeleke ukuthi kwethulwe maduze.
Ukuhunyushwa kwe-HDMI 2.2 Ukucaciswa kanye Nezinselele Zokuhlola Nokuqinisekisa
Emkhakheni wokudlulisa umsindo wedijithali nevidiyo, i-HDMI (Isixhumi esibonakalayo esinencazelo ephezulu ye-Multimedia) ibambe isikhundla esiphambili. Ngokusho kwedatha ekhishwe i-HDMI Licensing Administrator (HDMI LA) engqungqutheleni ye-CES 2025, inani lamadivayisi asekela i-HDMI lidlule amayunithi ayizigidi ezingu-900 ngo-2024, futhi isamba esiphelele sokuthunyelwa sesifinyelele kumayunithi ayizigidi eziyizinkulungwane ezingu-1.4. Njengoba izimakethe zidinga izinqumo eziphakeme, amanani okuvuselela aphakeme, kanye nolwazi olujulile luqhubeka nokukhula, njengokuthandwa kwama-TV amageyimu esizukulwane esilandelayo anezinhlelo zokusebenza ze-4K@240Hz kanye ne-AR/VR, Iforamu ye-HDMI isimemezele ngokusemthethweni ukucaciswa kwe-HDMI 2.2. Okulandelayo ukuchazwa kokuqanjwa okusha okuyisisekelo kwe-HDMI 2.2. Izinqubo ezintathu eziyinhloko zobuchwepheshe ze-HDMI 2.2 Ngokokukhishwa kwe-HDMI Forum, ukuthuthukiswa kwe-HDMI 2.2 kugxile ikakhulukazi emisebenzini emithathu eyinhloko, okuhloswe ngayo ukuhlangabezana nezidingo zokuthuthukiswa kobuchwepheshe bomsindo nokubukwayo eminyakeni eyishumi ezayo: 1. Ukuphindwa kabili kwe-Bandwidth: Ukuqhubekela ku-96Gbps FRL ubuchwepheshe. Ukuthuthukiswa okuphawuleka kakhulu ukuphindwa kabili okuqondile komkhawulokudonsa omkhulu ukusuka ku-HDMI 2.1's 48Gbps ukuya ku-96Gbps. Lokhu kugxuma kufinyelelwa ngobuchwepheshe obusha be-“Fixed Rate Link (FRL)”. Lokhu kukhuphuka komkhawulokudonsa okumangalisayo kuzovula amandla omsindo okubukwayo angakaze abonwe ngaphambili, okuhlanganisa: (1) Ukusekelwa kwezithombe ezicaciswe kakhulu ngaphandle kokucindezelwa: Iyakwazi ukusekela ngokomdabu i-4K@240Hz, 8K HDMI@120Hz, namanye amafomethi esithombe sekhwalithi ephezulu kakhulu nesilinganiso sokuvuselela. (2) Ukugcina isikhala sesikhathi esizayo: Ngobuchwepheshe bokucindezela ividiyo (DSC), ingasekela ukucaciswa okumangazayo okufana no-8K HDMI@240Hz, 10K@120Hz, kanye no-12K@120Hz. (3) Izicelo zokuhlangana zobuchwepheshe nezohwebo: Ukunikeza isisekelo esiqinile sezinhlelo zokusebenza ezidinga ukudluliswa kwedatha okukhulu, njenge-AR/VR/MR, imaging yezokwelapha, namaphaneli amakhulu edijithali. 2. Ikhebuli entsha ye-Ultra96 HDMI® Cable kanye Nohlelo Lokunikeza Izitifiketi; Ukuthwala ithrafikhi enkulu efika ku-96Gbps, ukucaciswa kwe-HDMI 2.2 kufaka phakathi i-“Ultra96 HDMI® Cable” entsha. Le ntambo izoba yingxenye yoHlelo Lwezitifiketi ze-HDMI, okusho ukuthi imodeli ngayinye ehlukene nobude bekhebula (njenge-Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) kufanele ihlolwe ngokuqinile nesitifiketi ngaphambi kokuba itholakalele ukuthengiswa. I-HDMI LA igcizelele engqungqutheleni ukubaluleka kokuthotshelwa kwe-supply chain, okuhlanganisa nokuqiniswa kwemikhiqizo engagunyaziwe nengathobeli. Lokhu kusho ukuthi isitifiketi esisemthethweni sizobaluleka kakhulu kunangaphambili. Lesi sinyathelo siqinisekisa ukuthi abathengi bangathenga imikhiqizo ehlangabezana nokucaciswayo futhi bangahamba ngokukhululeka emakethe yomhlaba. 3. Umsindisi wokuvumelanisa okulalelwayo nokubukwayo: I-Latency Indication Protocol (LIP) ibangela ukunyakaza kwezindebe kungafani nomsindo, okuyiphupho elibi kubasebenzisi abaningi betiyetha yasekhaya noma abasebenzisi besistimu yokulalelwayo nokubukwayo. Ikakhulukazi ezimeni lapho isignali idlula kumadivayisi amaningi (njengekhonsoli yegeyimu -> AVR -> TV) ngendlela “ye-multiple-hop”, inkinga yokubambezeleka iba nzima nakakhulu. I-HDMI 2.2 yethula i-Latency Indication Protocol (LIP) entsha sha, eyenza idivayisi engumthombo kanye nedivayisi yokubonisa zixhumane nezimo zazo zokulibaziseka ezilandelanayo, okuvumela isistimu ukuthi ivumelanise umsindo nevidiyo ngokuhlakanipha nangempumelelo kakhudlwana, ithuthukise kakhulu umuzwa womsebenzisi. I-HDMI 1.4 vs 2.1 vs 2.2 Ukuqhathaniswa Kwezicaciso Ukuze uqonde kangcono izinto ezintsha zobuchwepheshe ze-HDMI 2.2, ithebula lokuqhathanisa elilandelayo lihlanganiswe ngokukhethekile:

Izinselelo Zokuhlolwa Nesitifiketi se-HDMI 2.2 Ukukhishwa kwe-HDMI 2.2 kuzoletha izinselelo ezintsha ezimbalwa emazingeni ahlukene:

1. Ukuhlola Ungqimba Lomzimba (i-PHY): Inselele enkulu ilele kubuqotho besignali (Signal Integrity). Ngomkhawulokudonsa ongu-96 Gbps, umkhawulokudonsa ophakeme kakhulu ubeka izidingo eziqine ngendlela engakaze ibonwe kubuqotho besignali. Phakathi nenqubo yokuhlola, sidinga amathuluzi anembe kakhudlwana ukuze sihlaziye izinkomba ezibalulekile njengemidwebo yamehlo, i-jitter, ukulahlekelwa kokufaka, kanye ne-crosstalk ukuze kuqinisekiswe ukuzinza kwesignali phakathi nokudluliswa kwesivinini esikhulu. Amakhebula nezixhumi: Izintambo ezintsha ze-Ultra96 (okuhlanganisa i-Flexible HDMI, Ikhebula le-MINI HDMI, Ikhebula le-MICRO HDMI) kufanele lidlule izindinganiso zokuhlola eziqine kakhudlwana, futhi ukusebenza kwazo kumafrikhwensi aphezulu kuzoba okugxilwe kukho kwesitifiketi. Isikhungo sokuhlola esigunyaziwe esisemthethweni (i-ATC) sizosebenzisana eduze ne-HDMI Forum ukusungula isisombululo sokuhlola esiphelele.
2. Ukuhlolwa Kwesendlalelo Sephrothokholi (Iphrothokholi): Ubunkimbinkimbi bokuhlolwa kwephrothokholi bukhule kakhulu. Ukuqinisekiswa kwephrothokholi ye-LIP: I-Delay Indication Protocol (LIP) isici esisha esidinga amathuluzi akhethekile okuhlola iphrothokholi ukuze alingise izimo ezihlukahlukene zedivayisi ye-multi-hop futhi aqinisekise ukunemba kokuxhumana kwephrothokholi phakathi kwemithombo, ama-relay, namadivayisi wokubonisa. Inhlanganisela yefomethi enkulu: I-HDMI 2.2 isekela inhlanganisela enkulu kakhulu yokuxazululwa, izilinganiso zokuvuselela, amasampula e-chroma, nokujula kombala. Ngesikhathi sokuhlolwa, kuyadingeka ukuqinisekisa ukuthi umkhiqizo ungaxoxisana ngendlela efanele futhi ubonise ngezinhlanganisela ezihlukahlukene (njenge-144Hz HDMI, 8K HDMI), ikakhulukazi uma ukucindezelwa kwe-DSC kunikwe amandla, okuzokwandisa kakhulu ubunzima kanye nesikhathi sokuhlola.
Ukukhishwa kwe-HDMI 2.2′s Kuphawula Ingqopha-mlando Ebalulekile Ekuthuthukisweni Kobuchwepheshe Be-Audio-Visual Interface. Akukhona nje kuphela ukwanda komkhawulokudonsa, kodwa futhi kumelela ukuqala kwe-ecosystem entsha engabhekana nekhwalithi ephezulu kanye nokuhlangenwe nakho okusebenzisanayo kule minyaka eyishumi ezayo. Nakuba ukwamukelwa okusabalele kwemikhiqizo ye-HDMI 2.2 kusenesikhathi eside, ukubuyekezwa kobuchwepheshe akukaze kume. Izintambo ze-Ultra96 (okuhlanganisa i-Slim HDMI, Right Angle HDMI, Ikhebula le-MICRO HDMI) kulindeleke ukuthi zingene emakethe engxenyeni yesithathu noma yesine ka-2025. Masikwamukele ngokuhlanganyela ukufika kwenkathi entsha yekhwalithi yesithombe esiphezulu kakhulu nge-HDMI 2.2.
