Ukuphumelela okuThathu kwe-HDMI 2.2 kwi-ULTRA96 Certification

Ukuphumelela okuThathu kwe-HDMI 2.2 kwi-ULTRA96 Certification

Iintambo ze-HDMI 2.2 kufuneka ziphawulwe ngamagama athi "ULTRA96", ebonisa ukuba baxhasa i-bandwidth ukuya kwi-96Gbps.

Le ilebula iqinisekisa ukuba umthengi uthenge imveliso ehlangabezana neemfuno zabo, njengoko ikhebula le-HDMI 2.1 yangoku ine-bandwidth ephezulu ye-48 Gbps kuphela. Iforamu ye-HDMI iya kuvavanya ubude bentambo nganye ukuqinisekisa ukuthotyelwa, kwaye ilebula kufuneka ifakwe kwikhebula.
I-HDMI 2.2 inokudlulisa umxholo kwisisombululo esiphezulu se-12K kwi-120 fps okanye i-16K kwi-60 fps kwizixhobo ezixhaswayo, kwaye iphinde ixhase iifomathi ezilahlekileyo ezigcwele umbala, njengesisombululo se-8K HDMI kwi-60 fps / 4: 4: 4 kunye nesisombululo se-4K kwi-240 fps / 4: 4: 4, kunye nombala we-10-bit kunye nobunzulu be-10.
Ukongeza, i-HDMI 2.2 ixhotyiswe ngento entsha ebizwa ngokuba yi-Delay Indication Protocol (LIP), enokuphucula ukuvumelanisa kwe-audio-video. Oku kuya kuba luncedo ngakumbi kuqwalaselo lwenkqubo entsonkothileyo kubandakanya abamkeli bevidiyo yeaudio okanye izithethi ezingqongileyo.

NgeForam ye-HDMI ikhulula ngokusemthethweni iinkcukacha ezipheleleyo ze-HDMI inguqulo ye-2.2, iintambo eziqinisekisiweyo ezinxulumeneyo kunye nezixhobo ezihambelanayo kulindeleke ukuba ziqaliswe ngokukhawuleza.
Ukutolikwa kwe-HDMI 2.2 Iinkcukacha kunye neMingeni yoVavanyo kunye neSiqinisekiso
Kwintsimi yokuhanjiswa kwedijithali kunye nevidiyo, i-HDMI (i-High-Definition Multimedia Interface) ibambe indawo ehamba phambili. Ngokutsho kwedatha ekhutshwe nguMlawuli weLayisensi ye-HDMI (i-HDMI LA) kwinkomfa ye-CES 2025, inani lezixhobo ezixhasa i-HDMI ligqithise iiyunithi ze-900 zezigidi kwi-2024, kwaye i-cumulative total volume shipment volume ifike kwi-1.4 yeebhiliyoni zeeyunithi. Njengoko imarike ifuna izisombululo eziphezulu, amazinga aphezulu okuhlaziya, kunye namava amaninzi antywilayo aqhubeka ekhula, njengokuthandwa kweTV yesizukulwana esilandelayo kunye ne-4K @ 240Hz kunye nezicelo ze-AR / VR, i-HDMI Forum iye yazisa ngokusemthethweni i-HDMI 2.2 inkcazo. Oku kulandelayo kukutolikwa kwezinto ezintathu eziphambili zeteknoloji ye-HDMI 2.2. Izinto ezintathu ezisisiseko zeteknoloji ye-HDMI 2.2 Ngokokukhululwa kwe-HDMI Forum, ukuphuculwa kwe-HDMI 2.2 kugxininise kakhulu kwimisebenzi emithathu engundoqo, ejolise ekuhlangabezaneni neemfuno zophuhliso lweteknoloji ye-audio-visual kwiminyaka elishumi ezayo: 1. I-Bandwidth ephindwe kabini: Ukufudukela kwi-96Gbps iteknoloji ye-FRL. Ukuphuculwa okuphawulekayo kukuphindaphinda ngokuthe ngqo kwe-bandwidth ephezulu ukusuka kwi-HDMI 2.1's 48Gbps ukuya kwi-96Gbps. Lo mtsi uphunyezwa ngobuchwepheshe obutsha be-“Fixed Rate Link (FRL)”. Olu lwando lumangalisayo lwebhanwidth luya kuvula izakhono zomsindo-ezibonakalayo ezingazange zibonwe ngaphambili, kubandakanywa: (1) Ukuxhasa imifanekiso ecacileyo ephezulu ngaphandle koxinzelelo: Ukwazi ukuxhasa ngokwemveli i-4K @ 240Hz, 8K HDMI@120Hz, kunye nezinye iifomathi ze-ultra-high-high-high-refresh-refresh-rate image. (2) Ukugcina indawo yexesha elizayo: Ngokusebenzisa itekhnoloji yoxinzelelo lwevidiyo (i-DSC), inokuxhasa iinkcukacha ezimangalisayo ezifana ne-8K HDMI@240Hz, 10K@120Hz, kunye ne-12K@120Hz. (3) Intlanganiso yezicelo zeengcali kunye nezorhwebo: Ukubonelela ngesiseko esiluqilima kwizicelo ezifuna ukuhanjiswa kwedatha enkulu, njenge-AR / VR / MR, i-imaging yonyango, kunye neepaneli ezinkulu zedijithali. 2. INkqubo entsha ye-Ultra96 HDMI® Cable kunye neSiqinisekiso; Ukuthwala itrafikhi enkulu ukuya kuthi ga kwi-96Gbps, inkcazo ye-HDMI 2.2 iquka "i-Ultra96 HDMI® Cable" entsha. Le ntambo iya kuba yinxalenye yeNkqubo ye-HDMI yeSitifiketi se-Ultra, oku kuthetha ukuba imodeli nganye eyahlukileyo kunye nobude bekhebula (njenge-Slim HDMI, i-OD 3.0mm HDMI, i-Right Angle HDMI) kufuneka ihlolwe ngokungqongqo kunye nesitifiketi ngaphambi kokuba ifumaneke ukuthengiswa. I-HDMI LA igxininise kwinkomfa ukubaluleka kokuthotyelwa kwe-supply chain, kubandakanywa ukuchithwa kweemveliso ezingagunyaziswanga kunye nezingahambelaniyo. Oku kuthetha ukuba isatifikethi esisemthethweni siya kubaluleka ngakumbi kunangaphambili. Eli nyathelo liqinisekisa ukuba abathengi banokuthenga iimveliso ezihambelana neenkcukacha kwaye banokuhamba ngokukhululekileyo kwimarike yehlabathi. 3. Umsindisi we-audio-visual synchronization: I-Latency Indication Protocol (LIP) ibangela ukuba intshukumo yomlomo ihambelane nesandi, nto leyo eyingozi kuninzi lwabasebenzisi bethiyetha yasekhaya okanye abasebenzisi benkqubo ye-audio-visual entsonkothileyo. Ngokukodwa kwiimeko apho umqondiso udlula kwizixhobo ezininzi (ezifana nekhonsoli yomdlalo -> AVR -> iTV) ngendlela "ye-hop ezininzi", ingxaki yokulibaziseka iba mbi ngakumbi. I-HDMI 2.2 yazisa iProtocol yeLatency Indication (LIP) entsha, eyenza ukuba isixhobo somthombo kunye nesixhobo sokubonisa sinxibelelane neemeko zabo zokulibaziseka, ukuvumela inkqubo ukuba ivumelanise iaudio kunye nevidiyo ngobuchule nangempumelelo, iphucula kakhulu amava omsebenzisi. I-HDMI 1.4 vs 2.1 vs 2.2 Uthelekiso lweNgcaciso Ukuze uqonde ngcono izinto ezintsha zobuchwepheshe ze-HDMI 2.2, itheyibhile elandelayo yokuthelekisa iqulunqwe ngokukodwa:

Imingeni ye-HDMI 2.2 yoVavanyo kunye neSiqinisekiso Ukukhutshwa kwe-HDMI 2.2 kuya kuzisa imingeni emitsha emininzi kumanqanaba ahlukeneyo:

1. Uvavanyo lwePhysical Layer (PHY): Umceli mngeni ogqithisileyo ulele kwingqibelelo yomqondiso (Ukunyaniseka kweSiginali). Nge-bandwidth ye-96 Gbps, i-ultra-high bandwidth ibeka iimfuno ezingqongqo ngendlela engazange ibonwe ngaphambili kwimfezeko yesignali. Ngethuba lenkqubo yokuvavanya, sifuna izixhobo ezichanekileyo zokuhlalutya izikhombisi eziphambili ezifana nemizobo yamehlo, i-jitter, ilahleko yokufaka, kunye ne-crosstalk ukuqinisekisa ukuzinza kwesignali ngexesha lokudluliselwa kwesantya esiphezulu. Iintambo kunye neziqhagamshelo: Iintambo ze-Ultra96 ezintsha (kubandakanywa i-Flexible HDMI, i-MINI HDMI Cable, i-MICRO HDMI Cable) kufuneka idlule imigangatho yovavanyo engqongqo, kwaye ukusebenza kwabo kwiifrikhwensi eziphezulu kuya kuba yingqwalasela yesatifikethi. Iziko lokuvavanya eligunyazisiweyo elisemthethweni (ATC) liya kusebenzisana ngokusondeleyo ne-HDMI Forum ukuseka isisombululo esipheleleyo sokuvavanya.
2. Uvavanyo lweProtocol Layer (Protocol): Ubunzima bovavanyo lweprothokholi bunyuke kakhulu. Ukuqinisekiswa kweprothokholi ye-LIP: I-Delay Indication Protocol (LIP) luphawu olutsha olufuna izixhobo ezikhethekileyo zovavanyo lweprothokholi ukulinganisa iimeko ezahlukeneyo zesixhobo se-hop kunye nokuqinisekisa ukuchaneka konxibelelwano lweprotocol phakathi kwemithombo, iireyiyi kunye nezixhobo zokubonisa. Indibaniselwano yefomathi enkulu: I-HDMI 2.2 ixhasa indibaniselwano enkulu kakhulu yezisombululo, amaxabiso okuhlaziya, isampulu yechroma, kunye nobunzulu bombala. Ngexesha lokuvavanya, kuyimfuneko ukuqinisekisa ukuba umkhiqizo unokuxoxisana ngokuchanekileyo kwaye ubonise kwiintlobo ezahlukeneyo (ezifana ne-144Hz HDMI, i-8K HDMI), ngakumbi xa ukunyanzeliswa kwe-DSC kunikwe amandla, okuya kwandisa kakhulu ubunzima kunye nexesha lokuvavanya.
Ukukhutshwa kwe-HDMI 2.2's kuphawula iNqanaba eliBalulekileyo kuPhuhliso lweTekhnoloji ye-Audio-Visual Interface. Ayikokwanda kwe-bandwidth kuphela, kodwa ikwamele ukuqala kwenkqubo entsha yendalo enokuhlangabezana nomgangatho ophezulu kunye namava asebenzisanayo ngakumbi kwishumi leminyaka elizayo. Nangona ukwamkelwa ngokubanzi kweemveliso ze-HDMI ze-2.2 kusekho ixesha elide, ukuhlaziywa kweteknoloji akuzange kume. Iintambo ze-Ultra96 (kubandakanywa i-Slim HDMI, i-Right Angle HDMI, i-MICRO HDMI Cable) kulindeleke ukuba ingene kwimarike kwikota yesithathu okanye yesine ye-2025. Masikwamkele ngokudibeneyo ukufika kwexesha elitsha lomgangatho we-ultra-high kunye ne-HDMI 2.2.
