Peb Qhov Kev Tshawb Fawb Tshiab ntawm HDMI 2.2 hauv ULTRA96 Daim Ntawv Pov Thawj

Peb Qhov Kev Tshawb Fawb Tshiab ntawm HDMI 2.2 hauv ULTRA96 Daim Ntawv Pov Thawj

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

Daim ntawv lo no ua kom tus neeg yuav khoom yuav cov khoom uas ua tau raws li lawv xav tau, vim tias tam sim no HDMI 2.1 cable muaj qhov siab tshaj plaws tsuas yog 48 Gbps xwb. Lub Rooj Sab Laj HDMI yuav sim txhua qhov ntev ntawm cable kom paub tseeb tias ua raws li txoj cai, thiab daim ntawv lo yuav tsum tau lo rau ntawm cable.
HDMI 2.2 tuaj yeem xa cov ntsiab lus ntawm qhov siab tshaj plaws ntawm 12K ntawm 120 fps lossis 16K ntawm 60 fps rau cov khoom siv txhawb nqa, thiab nws kuj txhawb nqa cov hom ntawv xim puv npo tsis poob, xws li 8K HDMI daws teeb meem ntawm 60 fps / 4:4:4 thiab 4K daws teeb meem ntawm 240 fps / 4:4:4, nrog rau qhov tob xim ntawm 10-ntsis thiab 12-ntsis.
Ntxiv rau, HDMI 2.2 muaj ib qho tshiab hu ua Delay Indication Protocol (LIP), uas tuaj yeem txhim kho kev sib dhos suab-yeeb yaj kiab. Qhov no yuav pab tau tshwj xeeb rau cov kev teeb tsa system nyuaj dua suav nrog cov receivers suab-yeeb yaj kiab lossis cov neeg hais lus puag ncig.

Nrog rau HDMI Forum tshaj tawm cov lus qhia tag nrho ntawm HDMI version 2.2, cov cables tau ntawv pov thawj thiab cov khoom siv sib xws yuav tsum tau tso tawm sai sai no.
Kev Txhais Lus ntawm HDMI 2.2 Cov Lus Qhia thiab Cov Kev Cov Nyom ntawm Kev Ntsuas thiab Daim Ntawv Pov Thawj
Hauv kev xa xov tooj cua thiab video digital, HDMI (High-Definition Multimedia Interface) yog ib qho tseem ceeb tshaj plaws. Raws li cov ntaub ntawv tshaj tawm los ntawm HDMI Licensing Administrator (HDMI LA) ntawm lub rooj sib tham CES 2025, tus naj npawb ntawm cov khoom siv txhawb nqa HDMI tau tshaj 900 lab units hauv xyoo 2024, thiab tag nrho cov khoom xa tuaj tau mus txog 1.4 billion units. Raws li kev thov ntawm kev ua lag luam rau kev daws teeb meem siab dua, cov nqi refresh siab dua, thiab kev paub ntau dua txuas ntxiv mus, xws li kev nrov npe ntawm cov TV gaming tiam tom ntej nrog 4K @ 240Hz thiab AR / VR daim ntawv thov, HDMI Forum tau tshaj tawm HDMI 2.2 specification. Cov hauv qab no yog kev txhais lus ntawm peb lub hauv paus tseem ceeb ntawm HDMI 2.2. Peb lub hauv paus tseem ceeb ntawm HDMI 2.2 Raws li kev tshaj tawm los ntawm HDMI Forum, kev hloov kho ntawm HDMI 2.2 feem ntau tsom mus rau peb lub hauv paus tseem ceeb, lub hom phiaj los ua kom tau raws li qhov xav tau kev txhim kho ntawm cov thev naus laus zis audio-visual hauv kaum xyoo tom ntej: 1. Bandwidth ob npaug: Txav mus rau 96Gbps FRL thev naus laus zis. Qhov kev hloov kho tshiab tshaj plaws yog qhov ncaj qha ob npaug ntawm qhov siab tshaj plaws bandwidth los ntawm HDMI 2.1's 48Gbps mus rau 96Gbps. Qhov kev dhia no tau ua tiav los ntawm cov thev naus laus zis tshiab "Fixed Rate Link (FRL)". Qhov kev nce bandwidth zoo kawg no yuav qhib cov peev xwm suab-pom tsis tau muaj dua, suav nrog: (1) Txhawb nqa cov duab siab dua yam tsis muaj kev sib sau ua ke: Muaj peev xwm txhawb nqa 4K@240Hz, 8K HDMI@120Hz, thiab lwm yam duab zoo heev thiab siab-refresh-rate. (2) Tseg qhov chaw rau yav tom ntej: Los ntawm kev siv tshuab video compression (DSC), nws tuaj yeem txhawb nqa cov lus qhia zoo kawg li xws li 8K HDMI@240Hz, 10K@120Hz, thiab txawm tias 12K@120Hz. (3) Ua raws li cov ntawv thov kev tshaj lij thiab kev lag luam: Muab lub hauv paus ruaj khov rau cov ntawv thov uas xav tau kev xa cov ntaub ntawv loj, xws li AR/VR/MR, kev thaij duab kho mob, thiab cov vaj huam sib luag digital loj. 2. Ultra96 HDMI® Cable thiab Certification Program tshiab; Yuav kom nqa tau cov tsheb khiav loj txog li 96Gbps, HDMI 2.2 specification suav nrog "Ultra96 HDMI® Cable" tshiab. Lub cable no yuav dhau los ua ib feem ntawm HDMI Ultra Certification Program, txhais tau tias txhua tus qauv sib txawv thiab ntev ntawm cable (xws li Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) yuav tsum tau dhau los ntawm kev kuaj xyuas thiab ntawv pov thawj nruj ua ntej muaj rau kev muag khoom. HDMI LA tau hais txog ntawm lub rooj sib tham qhov tseem ceeb ntawm kev ua raws li cov khoom xa tuaj, suav nrog kev tawm tsam cov khoom tsis raug cai thiab tsis ua raws li. Qhov no txhais tau tias daim ntawv pov thawj raug cai yuav tseem ceeb dua puas tau. Qhov kev txav no ua kom ntseeg tau tias cov neeg siv khoom tuaj yeem yuav cov khoom uas ua tau raws li cov lus qhia thiab tuaj yeem txav mus los tau yooj yim hauv kev lag luam thoob ntiaj teb. 3. Tus cawm seej ntawm kev sib dhos suab-pom: Latency Indication Protocol (LIP) ua rau lub suab txav tsis phim lub suab, uas yog qhov phem rau ntau tus neeg ua yeeb yam hauv tsev lossis cov neeg siv suab-pom nyuaj. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas lub teeb liab hla ntau lub cuab yeej (xws li lub tshuab ua si -> AVR -> TV) hauv "ntau-hop", qhov teeb meem qeeb zuj zus tuaj. HDMI 2.2 qhia txog Latency Indication Protocol (LIP) tshiab, uas ua rau lub cuab yeej qhov chaw thiab lub cuab yeej tso saib sib txuas lus lawv cov xwm txheej qeeb, tso cai rau lub kaw lus los sib dhos suab thiab video kom ntse dua thiab ua haujlwm tau zoo, txhim kho qhov kev paub ntawm tus neeg siv. HDMI 1.4 vs 2.1 vs 2.2 Kev Sib Piv Cov Lus Qhia Txhawm rau kom nkag siab zoo dua txog kev tsim kho tshiab ntawm HDMI 2.2, cov lus sib piv hauv qab no tau muab sau tshwj xeeb:

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

1. Kev Ntsuas Txheej Txheem Lub Cev (PHY): Qhov kev sib tw loj tshaj plaws yog kev ncaj ncees ntawm lub teeb liab (Kev Ncaj Ncees ntawm Lub Teeb Liab). Nrog rau bandwidth ntawm 96 Gbps, qhov bandwidth siab heev ua rau muaj kev cai nruj heev rau kev ncaj ncees ntawm lub teeb liab. Thaum lub sijhawm sim, peb xav tau cov cuab yeej kom meej dua los tshuaj xyuas cov cim qhia tseem ceeb xws li daim duab qhov muag, jitter, kev poob ntawm kev ntxig, thiab crosstalk kom ntseeg tau tias lub teeb liab ruaj khov thaum lub sijhawm xa xov ceev. Cov cables thiab cov connectors: Cov cables Ultra96 tshiab (suav nrog Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) yuav tsum dhau cov qauv kev sim nruj dua, thiab lawv cov kev ua tau zoo ntawm cov zaus siab yuav yog qhov tseem ceeb ntawm daim ntawv pov thawj. Lub chaw sim uas tau tso cai (ATC) yuav koom tes nrog HDMI Forum los tsim kom muaj kev daws teeb meem kev sim tiav.
2. Kev Ntsuas Txheej Txheem (Protocol): Qhov nyuaj ntawm kev sim txheej txheem tau nce ntxiv ntau heev. Kev txheeb xyuas txheej txheem LIP: Lub Delay Indication Protocol (LIP) yog ib qho tshiab uas xav tau cov cuab yeej kuaj txheej txheem tshwj xeeb los ua qauv ntau yam xwm txheej ntawm ntau lub cuab yeej thiab txheeb xyuas qhov tseeb ntawm kev sib txuas lus txheej txheem ntawm cov chaw, relays, thiab cov khoom siv tso saib. Kev sib xyaw ua ke ntawm hom ntawv loj: HDMI 2.2 txhawb nqa kev sib xyaw ua ke loj heev ntawm kev daws teeb meem, tus nqi refresh, chroma sampling, thiab qhov tob xim. Thaum lub sijhawm sim, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom tuaj yeem sib tham thiab tso saib hauv ntau yam kev sib xyaw ua ke (xws li 144Hz HDMI, 8K HDMI), tshwj xeeb tshaj yog thaum DSC compression qhib, uas yuav ua rau qhov nyuaj thiab lub sijhawm ntawm kev sim ntau ntxiv.
Kev Tso Tawm HDMI 2.2 Qhia Txog Lub Caij Nyoog Tseem Ceeb Hauv Kev Tsim Kho Tshuab Audio-Visual Interface. Nws tsis yog tsuas yog kev nce bandwidth xwb, tab sis kuj yog qhov pib ntawm lub ecosystem tshiab uas tuaj yeem daws tau qhov zoo dua thiab kev sib tham ntau dua hauv kaum xyoo tom ntej. Txawm hais tias kev siv dav dav ntawm cov khoom HDMI 2.2 tseem nyob deb me ntsis, kev hloov kho tshiab ntawm thev naus laus zis yeej tsis tau tso tseg. Ultra96 cables (suav nrog Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) yuav nkag mus rau hauv kev ua lag luam hauv peb lub hlis twg lossis plaub ntawm xyoo 2025. Cia peb ua ke txais tos lub sijhawm tshiab ntawm cov duab zoo ultra-high nrog HDMI 2.2.
