Peb Kev Ua Haujlwm ntawm HDMI 2.2 hauv ULTRA96 Certification

Peb Kev Ua Haujlwm ntawm HDMI 2.2 hauv ULTRA96 Certification

HDMI 2.2 cables yuav tsum tau cim nrog cov lus "ULTRA96", uas qhia tias lawv txhawb nqa bandwidth txog li 96Gbps.

Daim ntawv lo no ua kom cov neeg yuav khoom yuav khoom raws li lawv cov kev xav tau, vim tam sim no HDMI 2.1 cable muaj qhov siab tshaj plaws bandwidth ntawm 48 Gbps. Lub Rooj Sab Laj HDMI yuav sim txhua qhov ntev ntawm cov kab hluav taws xob kom ntseeg tau tias kev ua raws cai, thiab daim ntawv lo yuav tsum tau muab tso rau hauv lub cable.
HDMI 2.2 tuaj yeem xa cov ntsiab lus ntawm qhov kev daws teeb meem siab tshaj plaws ntawm 12K ntawm 120 fps lossis 16K ntawm 60 fps rau cov khoom siv txhawb nqa, thiab nws kuj tseem txhawb nqa cov xim tsis muaj xim, xws li 8K HDMI daws teeb meem ntawm 60 fps / 4: 4: 4 thiab 4K daws teeb meem ntawm 240 fps / 4: 4: 10-ntsis xim thiab 2-ntsis qhov tob.
Tsis tas li ntawd, HDMI 2.2 tau nruab nrog cov yam ntxwv tshiab hu ua Delay Indication Protocol (LIP), uas tuaj yeem txhim kho audio-video synchronization. Qhov no yuav muaj txiaj ntsig tshwj xeeb rau ntau qhov kev teeb tsa kev teeb tsa nrog rau cov suab-video receivers lossis cov neeg hais lus ib puag ncig.

Nrog rau lub rooj sab laj HDMI tau tshaj tawm cov lus qhia ua tiav ntawm HDMI version 2.2, cov ntaub ntawv pov thawj cuam tshuam thiab cov khoom siv tau zoo yuav tsum tau pib sai sai.
Kev txhais lus ntawm HDMI 2.2 Specifications thiab cov kev sib tw ntawm kev xeem thiab ntawv pov thawj
Hauv kev xa xov digital audio thiab video, HDMI (High-Definition Multimedia Interface) tuav txoj haujlwm ua thawj coj. Raws li cov ntaub ntawv tso tawm los ntawm HDMI Licensing Administrator (HDMI LA) ntawm lub rooj sib tham CES 2025, tus naj npawb ntawm cov cuab yeej txhawb nqa HDMI tau tshaj 900 lab units hauv 2024, thiab cov khoom xa tuaj tag nrho tau nce mus txog 1.4 billion units. Raws li kev lag luam xav tau cov kev daws teeb meem siab dua, kev hloov tshiab siab dua, thiab cov kev paub dhau los txuas ntxiv nce ntxiv, xws li kev nyiam ntawm cov TV tshiab tom ntej nrog 4K @ 240Hz thiab AR / VR daim ntawv thov, HDMI Lub Rooj Sab Laj tau tshaj tawm txog HDMI 2.2 specification. Cov hauv qab no yog kev txhais ntawm peb qhov kev tsim kho tshiab ntawm HDMI 2.2. Peb qhov tseem ceeb thev naus laus zis tshiab ntawm HDMI 2.2 Raws li kev tso tawm los ntawm HDMI Lub Rooj Sab Laj, kev hloov kho ntawm HDMI 2.2 feem ntau tsom mus rau peb lub luag haujlwm tseem ceeb, txhawm rau ua kom tau raws li cov kev xav tau ntawm kev siv suab-visual technology hauv kaum xyoo tom ntej: 1. Bandwidth ob npaug: Tsiv mus rau 96Gbps FRL thev naus laus zis. Qhov kev hloov kho tseem ceeb tshaj plaws yog qhov ncaj qha ob npaug ntawm qhov siab tshaj plaws bandwidth ntawm HDMI 2.1′s 48Gbps rau 96Gbps. Qhov leap no tau ua tiav los ntawm qhov tshiab "Fixed Rate Link (FRL) technology". Qhov kev xav tsis thoob qhov kev nce qib no yuav qhib lub peev xwm uas tsis tau pom dua ua ntej, suav nrog: (1) Txhawb cov duab tshwj xeeb siab dua yam tsis muaj compression: Muaj peev xwm txhawb nqa 4K @ 240Hz, 8K HDMI @ 120Hz, thiab lwm yam ultra-high-quality thiab high-refresh-rate duab hom. (2) Txuag qhov chaw rau yav tom ntej: Los ntawm kev siv tshuab compression video (DSC), nws tuaj yeem txhawb kev xav tsis thoob xws li 8K HDMI @ 240Hz, 10K @ 120Hz, thiab txawm tias 12K @ 120Hz. (3) Kev sib tham txog kev tshaj lij thiab kev lag luam: muab lub hauv paus ruaj khov rau cov ntawv thov uas xav tau cov ntaub ntawv loj xa mus, xws li AR / VR / MR, kev kho mob duab, thiab cov vaj huam sib luag digital loj. 2. Tshiab Ultra96 HDMI® Cable thiab Certification Program; Txhawm rau nqa cov tsheb loj mus txog 96Gbps, HDMI 2.2 specification suav nrog "Ultra96 HDMI® Cable". Cov cable no yuav dhau los ua ib feem ntawm HDMI Ultra Certification Program, txhais tau hais tias txhua tus qauv sib txawv thiab ntev ntawm cable (xws li Slim HDMI, OD 3.0mm HDMI, Txoj Cai Lub Hwjchim HDMI) yuav tsum tau ua nruj me ntsis kuaj thiab ntawv pov thawj ua ntej muaj muag. HDMI LA tau hais tawm hauv lub rooj sib tham txog qhov tseem ceeb ntawm kev ua raws li cov saw hlau, suav nrog kev ua txhaum ntawm cov khoom tsis raug cai thiab tsis ua raws cai. Qhov no txhais tau hais tias daim ntawv pov thawj raug cai yuav tseem ceeb dua puas tau. Qhov kev txav no ua kom cov neeg siv khoom tuaj yeem yuav cov khoom lag luam uas ua tau raws li qhov tshwj xeeb thiab tuaj yeem txav mus los hauv kev lag luam thoob ntiaj teb. 3. Tus Cawm Seej ntawm audio-visual synchronization: Lub Latency Indication Protocol (LIP) ua rau lub di ncauj txav tsis zoo rau lub suab, uas yog npau suav phem rau ntau lub tsev ua yeeb yam lossis cov neeg siv suab-visual system complex. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas lub teeb liab dhau los ntawm ntau yam khoom siv (xws li game console -> AVR -> TV) nyob rau hauv "ntau-hop", qhov teeb meem qeeb yuav hnyav dua. HDMI 2.2 qhia txog lub npe tshiab Latency Indication Protocol (LIP), uas tso cai rau cov khoom siv thiab cov khoom siv los sib txuas lus lawv cov xwm txheej qeeb, tso cai rau lub kaw lus synchronize suab thiab yees duab ntau ntse thiab ua tau zoo, txhim kho cov neeg siv kev paub. HDMI 1.4 vs 2.1 vs 2.2 Specification Sib piv Kom nkag siab zoo dua cov kev tsim kho tshiab ntawm HDMI 2.2, cov lus sib piv hauv qab no tau muab tso ua ke tshwj xeeb:

Cov Kev Sib Tw ntawm HDMI 2.2 Kev Ntsuas thiab Ntawv Pov Thawj Kev tso tawm ntawm HDMI 2.2 yuav coj ntau yam kev sib tw tshiab ntawm ntau qib:

1. Kev Ntsuas Lub Cev Lub Cev (PHY) Kev Ntsuas: Qhov kev sib tw loj yog nyob rau hauv lub teeb liab kev ncaj ncees (Signal Integrity). Nrog ib tug bandwidth ntawm 96 Gbps, lub ultra-high bandwidth imposes unprecedentedly nruj kev cai ntawm lub teeb liab kev ncaj ncees. Thaum lub sij hawm xeem txheej txheem, peb xav tau cov cuab yeej meej ntxiv los txheeb xyuas cov cim tseem ceeb xws li daim duab qhia qhov muag, jitter, qhov poob, thiab crosstalk los xyuas kom meej qhov ruaj khov ntawm cov teeb liab thaum lub sij hawm kev sib kis ceev. Cables thiab connectors: Cov tshiab Ultra96 cables (xws li Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) yuav tsum dhau cov qauv nruj dua, thiab lawv cov kev ua tau zoo ntawm cov khoom siv siab yuav yog qhov tseem ceeb ntawm daim ntawv pov thawj. Lub chaw kuaj kev tso cai raug cai (ATC) yuav koom tes nrog HDMI Lub Rooj Sib Tham los tsim kom muaj kev sim ua tiav.
2. Cov Txheej Txheem Txheej Txheem (Txoj Cai) Kev Ntsuas: Qhov nyuaj ntawm kev sim raws tu qauv tau nce ntau. LIP raws tu qauv: Lub ncua sij hawm Indication Protocol (LIP) yog ib tug tshiab feature uas yuav tsum tau tshwj xeeb raws tu qauv kuaj cov cuab yeej los simulate ntau yam multi-hop ntaus ntawv scenarios thiab xyuas qhov tseeb ntawm raws tu qauv kev sib txuas lus ntawm qhov chaw, relays, thiab tso saib li. Kev sib xyaw ua ke loj heev: HDMI 2.2 txhawb nqa kev sib xyaw ua ke loj heev ntawm kev daws teeb meem, tus nqi refresh, chroma sampling, thiab xim tob. Thaum lub sij hawm sim, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom tuaj yeem sib tham tau thiab tso saib hauv ntau qhov sib txuas (xws li 144Hz HDMI, 8K HDMI), tshwj xeeb tshaj yog thaum DSC compression qhib, uas yuav ua rau kom qhov nyuaj thiab lub sijhawm ntawm kev sim.
HDMI 2.2′s tso tawm cim ib qho tseem ceeb Milestone nyob rau hauv Audio-Visual Interface Technology Development. Nws tsis yog tsuas yog nce hauv bandwidth xwb, tab sis kuj yog qhov pib ntawm lub ecosystem tshiab uas tuaj yeem tiv nrog kev ua tau zoo dua thiab muaj kev sib tham ntau dua hauv kaum xyoo tom ntej. Txawm hais tias kev siv dav dav ntawm HDMI 2.2 cov khoom lag luam tseem muaj qee lub sijhawm, qhov hloov tshiab ntawm thev naus laus zis tsis tau tso tseg. Ultra96 cables (xws li Slim HDMI, Txoj Cai Angle HDMI, MICRO HDMI Cable) yuav tsum nkag mus rau hauv kev lag luam hauv peb lossis plaub lub hlis twg ntawm 2025. Wb koom ua ke txais tos tuaj txog ntawm lub sijhawm tshiab ntawm cov duab zoo nrog HDMI 2.2.
