Impinduka eshatu za HDMI 2.2 mu kwemeza ULTRA96

Insinga za HDMI 2.2 zigomba kuba zanditseho amagambo "ULTRA96", bigaragaza ko zishyigikira umuvuduko wa interineti ugera kuri 96Gbps.

Iki kirango cyemeza ko umuguzi agura ibicuruzwa byujuje ibisabwa, kuko insinga ya HDMI 2.1 iriho ubu ifite umuvuduko ntarengwa wa 48 Gbps gusa. HDMI Forum izagerageza buri burebure bwa insinga kugira ngo irebe ko yujuje ibisabwa, kandi icyangombwa kigomba gushyirwa kuri insinga.
HDMI 2.2 ishobora kohereza ibintu ku rugero ntarengwa rwa 12K kuri 120 fps cyangwa 16K kuri 60 fps ku bikoresho bishyigikiwe, kandi inashyigikira imiterere y'amabara yuzuye idatakaza, nka 8K HDMI resolution kuri 60 fps / 4:4:4 na 4K resolution kuri 240 fps / 4:4:4, ifite ubujyakuzimu bw'amabara ya 10-bit na 12-bit.
Byongeye kandi, HDMI 2.2 ifite imikorere mishya yitwa Delay Indication Protocol (LIP), ishobora kunoza guhuza amajwi n'amashusho. Ibi bizaba ingirakamaro cyane cyane ku miterere y'imikorere igoye ya sisitemu harimo n'ibikoresho byakira amajwi n'amashusho cyangwa indangururamajwi zikikije.

Kubera ko HDMI Forum ishyize ahagaragara ku mugaragaro ibisabwa byose bya HDMI verisiyo ya 2.2, insinga zemewe n'ibikoresho bihuye nabyo biteganijwe ko bizashyirwa ahagaragara vuba.
Gusobanura Ibisobanuro bya HDMI 2.2 n'imbogamizi zo gupima no kwemeza
Mu rwego rwo kohereza amajwi n'amashusho mu buryo bwa digitale, HDMI (High-Definition Multimedia Interface) ifite umwanya wa mbere. Dukurikije amakuru yashyizwe ahagaragara n'Umuyobozi ushinzwe gutanga impushya za HDMI (HDMI LA) mu nama ya CES 2025, umubare w'ibikoresho bifasha HDMI warenze miliyoni 900 mu 2024, kandi umubare w'ibikoresho byose hamwe wageze kuri miliyari 1.4. Uko isoko risaba ubushobozi bwo kongera ubushobozi, kuvugurura ibishya, n'uburambe bwinshi bukomeje kwiyongera, nko gukurura televiziyo z'imikino zo mu gisekuru gitaha zifite porogaramu za 4K@240Hz na AR/VR, HDMI Forum yatangaje ku mugaragaro ibisobanuro bya HDMI 2.2. Ibi bikurikira ni ibisobanuro by'udushya dutatu tw'ingenzi twa HDMI 2.2. Udushya dutatu tw'ingenzi twa HDMI 2.2 Dukurikije ibyatangajwe n'Ihuriro rya HDMI, kuvugurura HDMI 2.2 byibanda ahanini ku mirimo itatu y'ingenzi, igamije guhaza ibyifuzo by'iterambere ry'ikoranabuhanga ry'amajwi n'amashusho mu myaka icumi iri imbere: 1. Gukuba kabiri bandwidth: Kugana ikoranabuhanga rya 96Gbps FRL. Iterambere rigaragara cyane ni ukwikuba kabiri kw'umurongo ntarengwa wa HDMI kuva kuri 48Gbps ya HDMI 2.1 kugeza kuri 96Gbps. Iri terambere rigerwaho binyuze mu ikoranabuhanga rishya rya "Fixed Rate Link (FRL). Iri terambere ritangaje rya bandwidth rizafungura ubushobozi budasanzwe bw'amajwi n'amashusho, harimo: (1) Gushyigikira amashusho yo hejuru nta gukanda: Ishobora gushyigikira 4K@240Hz, 8K HDMI@120Hz, n'izindi format z'amashusho nziza cyane kandi zinoze. (2) Kubika umwanya w'ejo hazaza: Binyuze mu ikoranabuhanga ryo gukanda videwo (DSC), ishobora gushyigikira ibisobanuro bitangaje nka 8K HDMI@240Hz, 10K@120Hz, ndetse na 12K@120Hz. (3) Guhura na porogaramu z'umwuga n'iz'ubucuruzi: Gutanga ishingiro rikomeye rya porogaramu zisaba kohereza amakuru menshi, nka AR/VR/MR, amashusho y'ubuvuzi, n'ibikoresho binini bya digitale. 2. Gahunda nshya ya Ultra96 HDMI® Cable and Certification; Kugira ngo umuvuduko munini w’itumanaho ugere kuri 96Gbps ugere kuri 96Gbps, ibisobanuro bya HDMI 2.2 birimo "Insinga nshya ya Ultra96 HDMI®". Iyi nsinga izaba igice cya Gahunda ya HDMI Ultra Certification, bivuze ko buri bwoko butandukanye n’uburebure bw’insinga (nka Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) bigomba kugeragezwa cyane no kwemezwa mbere yo kugurishwa. HDMI LA yashimangiye muri iyi nama akamaro ko kubahiriza amategeko agenga imiyoboro y’itumanaho, harimo no kurwanya ibicuruzwa bitemewe n’ibitemewe. Ibi bivuze ko kwemezwa kwemewe bizaba ingenzi kurusha mbere hose. Iyi ntambwe iremeza ko abaguzi bashobora kugura ibicuruzwa byujuje ibisabwa kandi bishobora kugenda mu bwisanzure ku isoko ry’isi. 3. Umucunguzi wo guhuza amajwi n’amashusho: Protocol y’ibipimo bya Latency (LIP) ituma iminwa idahuza n’amajwi, ibi bikaba ari ikibazo gikomeye ku bakoresha sinema zo mu rugo cyangwa sisitemu ikomeye y’amajwi n’amashusho. Cyane cyane mu bihe aho ikimenyetso kinyura mu bikoresho byinshi (nka konsole y’imikino -> AVR -> TV) mu buryo bwa "multiple-hop", ikibazo cyo gutinda kirushaho gukomera. HDMI 2.2 izana Protocole nshya y’ikimenyetso cya Latency (LIP), ituma igikoresho gikomokaho n’igikoresho cyo kwerekana amashusho bishobora kugaragaza imiterere yabyo yo gutinda, bigatuma sisitemu ihuza amajwi na videwo mu buryo bw’ubwenge kandi bunoze, binongera cyane ubunararibonye bw’umukoresha. HDMI 1.4 vs 2.1 vs 2.2 Igereranya ry’ibisobanuro Kugira ngo usobanukirwe neza udushya mu ikoranabuhanga rya HDMI 2.2, imbonerahamwe ikurikira yo kugereranya yakusanyijwe by’umwihariko:

Imbogamizi zo Gupima no Kwemeza HDMI 2.2 Isohoka rya HDMI 2.2 rizazana imbogamizi nshya nyinshi ku nzego zitandukanye:

1. Isuzuma ry’Icyiciro cy’Uburyo (PHY): Ikibazo gikomeye kiri mu buziranenge bw’ikimenyetso (Ubuziranenge bw’Ikimenyetso). Hamwe n’ubushobozi bwa bandwidth bwa 96 Gbps, uburebure bwa bandwidth buri hejuru cyane bushyiraho ibisabwa bikomeye cyane ku buziranenge bw’ikimenyetso. Mu gihe cyo gupima, dukeneye ibikoresho binonosoye byo gusesengura ibimenyetso by’ingenzi nka eye diagram, jitter, insertion loss, na crosstalk kugira ngo hamenyekane ko ikimenyetso gihamye mu gihe cyo kohereza umuvuduko mwinshi. Insinga n’ibihuza: Insinga nshya za Ultra96 (zirimo Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) zigomba kunyura mu bipimo bihamye byo gupima, kandi imikorere yazo ku murongo wo hejuru ni yo izaba yibandwaho mu kwemeza. Ikigo cyemewe cyo gupima (ATC) kizakorana bya hafi n’ihuriro rya HDMI kugira ngo gishyireho igisubizo cyuzuye cyo gupima.
2. Isuzuma rya Protocol Layer (Protocol): Ingano y'igerageza rya protocole yariyongereye cyane. Igenzura rya protocole ya LIP: Protocol ya Delay Indication (LIP) ni ikintu gishya gisaba ibikoresho byihariye byo gupima protocole kugira ngo byigane ibintu bitandukanye byo gukoresha ikoranabuhanga rya multi-hop no kugenzura ukuri kw'itumanaho rya protocole hagati y'amasoko, relays, n'ibikoresho byo kwerekana. Ihuriro rikomeye ry'imiterere: HDMI 2.2 ishyigikira uruvange runini cyane rw'ibisubizo, igipimo cyo kuvugurura, isuzuma rya chroma, n'ubujyakuzimu bw'amabara. Mu gihe cyo gupima, ni ngombwa kwemeza ko ibicuruzwa bishobora kuvugana neza no kwerekana mu buryo bunyuranye (nka 144Hz HDMI, 8K HDMI), cyane cyane iyo DSC ifunguye, ibyo bizongera cyane uburemere n'igihe cyo gupima.
Gusohora HDMI 2.2 ni ikimenyetso cy'ingenzi mu iterambere ry'ikoranabuhanga rya Audio-Visual Interface. Ntabwo ari ukwiyongera kwa bandwidth gusa, ahubwo ni n'intangiriro y'urusobe rw'ibinyabuzima rushya rushobora guhangana n'ubwiza bwo hejuru n'uburambe bwo gushyikirana mu myaka icumi iri imbere. Nubwo gukoresha ibikoresho bya HDMI 2.2 bikiri hafi igihe, kuvugurura ikoranabuhanga ntibyigeze bihagarara. Insinga za Ultra96 (zirimo Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) ziteganijwe kwinjira ku isoko mu gihembwe cya gatatu cyangwa icya kane cya 2025. Reka dufatanye kwakira igihe gishya cy'ubwiza bw'amashusho yo hejuru cyane hamwe na HDMI 2.2.
