Taw qhia rau DisplayPort, HDMI thiab Hom-C Interfaces
Thaum Lub Kaum Ib Hlis 29, 2017, HDMI Forum, Inc. tshaj tawm qhov tso tawm ntawm HDMI 2.1, 48Gbps HDMI, thiab 8K HDMI specifications, ua rau lawv muaj rau txhua tus neeg siv HDMI 2.0. Tus qauv tshiab txhawb nqa 10K daws teeb meem @ 120Hz (10K HDMI, 144Hz HDMI), nrog cov bandwidth tau nce mus rau 48Gbps, thiab qhia txog dynamic HDR thiab hloov pauv hloov tshiab (VRR) thev naus laus zis.
Thaum Lub Xya Hli 26, 2017, USB 3.0 Promoter Group alliance, suav nrog cov tuam txhab thev naus laus zis xws li Apple, HP, Intel, thiab Microsoft, tshaj tawm USB 3.2 tus qauv (USB 3.1 C TO C, USB C 10Gbps, Hom C Txiv neej TO Txiv neej), uas txhawb nqa dual-channel 20GbpsC kis tau tus mob raws li cov lus pom zoo.
Thaum Lub Peb Hlis 3, 2016, VESA (Video Electronics Standards Association) tau tshaj tawm cov qauv tshiab ntawm tus qauv xa tawm suab, DisplayPort 1.4. Cov qauv no txhawb nqa 8K @ 60Hz thiab 4K @ 120Hz, thiab thawj zaug sib koom ua ke cov duab kwj compression technology (DSC 1.2).

Cia siab tias yuav tso tawm cov qauv tshiab
DisplayPort 1.4 tus qauv tso tawm! Txhawb 60Hz 8K video
Thaum Lub Peb Hlis 1st, VESA (Video Electronics Standards Association) tau tshaj tawm cov qauv tshiab ntawm tus qauv xa tawm suab-visual DisplayPort 1.4. Tus txheej txheem tshiab ntxiv txhim kho lub peev xwm xa cov yeeb yaj kiab thiab cov ntaub ntawv los ntawm Hom-C (USB C 10Gbps, 5A 100W USB C Cable), thaum txhawb nqa HDR metadata kis tau tus mob thiab txuas ntxiv cov lus tshwj xeeb. Tus qauv tshiab tau suav tias yog thawj qhov hloov tshiab loj tom qab tso tawm ntawm DisplayPort 1.3 thaum lub Cuaj Hlis 2014.
Tib lub sijhawm, qhov no kuj yog thawj DP tus qauv uas txhawb nqa DSC 1.2 (Display Stream Compression) thev naus laus zis. Hauv DSC 1.2 version, 3: 1 lossless video kwj compression tuaj yeem tso cai.
Qhov "Lwm Hom (Alt Mode)" muab los ntawm DP 1.3 tus qauv twb tau txhawb nqa kev sib kis ntawm cov yeeb yaj kiab thiab cov ntaub ntawv ntws los ntawm USB Hom-C thiab Thunderbolt interfaces. Thaum DP 1.4 siv nws ib kauj ruam ntxiv, tso cai rau tib lub sijhawm sib kis ntawm cov yeeb yaj kiab siab txhais thaum SuperUSB (USB 3.0) siv rau cov ntaub ntawv xa mus.
Ntxiv rau, DP 1.4 yuav txhawb nqa 60Hz 8K daws teeb meem (7680 x 4320) HDR video nrog rau 120Hz 4K HDR video.
Lwm qhov hloov tshiab ntawm DP 1.4 yog raws li hauv qab no:
1. Forward Error Correction (FEC): Ib feem ntawm DSC 1.2 thev naus laus zis, nws hais txog qhov kev ua txhaum cai tsim nyog thaum compressing video rau cov zis tawm sab nraud.
2. HDR Metadata Transmission: Los ntawm kev siv "cov ntaub ntawv thib ob pob ntawv" hauv DP tus qauv, nws muab kev txhawb nqa rau CTA 861.3 tus qauv tam sim no, uas muaj txiaj ntsig zoo rau DP-HDMI 2.0a kev hloov pauv raws tu qauv. Tsis tas li ntawd, nws muab cov ntaub ntawv hloov pauv tau yooj yim dua metadata packet kis tau tus mob, txhawb nqa HDR dynamic yav tom ntej.
3. Kev xa tawm suab nthuav dav: Qhov kev qhia tshwj xeeb no tuaj yeem suav nrog 32-ntsis audio channels, 1536kHz sampling rate, thiab tag nrho cov suab nrov uas paub tam sim no.
VESA hais tias DP 1.4 yuav dhau los ua tus qauv zoo tshaj plaws interface kom tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob high-end.
Lub hom phiaj ntawm qhov yug ntawm Displayport yog qhov tseeb heev - kom tshem tawm HDMI. Yog li ntawd, piv rau HDMI, nws tsis muaj ntawv pov thawj interface lossis tus nqi cai, thiab tau sau ntau lub tuam txhab loj hauv kev lag luam zaub los tsim lub koom haum VISA los sib tw nrog HDMI koom haum. Cov npe suav nrog ntau lub tuam txhab high-end chip thiab cov khoom siv hluav taws xob, xws li Intel, NVIDIA, AMD, Apple, Lenovo, HP, thiab lwm yam. Yog li, nws tuaj yeem pom tias lub zog ntawm Displayport hnyav npaum li cas. Qhov kawg tshwm sim ntawm qhov kev ua si yog paub rau txhua tus! Rau Displayport interface, vim yog qhov kev txav mus los ntawm HDMI interface, cov txiaj ntsig nrov ntawm Displayport interface hauv ntau lub teb tsis tau zoo. Txawm li cas los xij, tus ntsuj plig tsis tu ncua ntawm Displayport interface kuj tseem ceeb rau HDMI kom txhim kho. Kev ua si ntawm ob leeg yuav txuas ntxiv mus rau yav tom ntej.
Thaum Lub Kaum Ib Hlis 28th, tus thawj coj ntawm HDMI Lub Rooj Sib Tham tau tshaj tawm qhov kev tshaj tawm ntawm HDMI 2.1 cov qauv kev tshaj lij.
Piv nrog rau ua ntej, qhov kev hloov pauv tseem ceeb tshaj plaws yog qhov kev nce qib hauv bandwidth, uas tam sim no tuaj yeem txhawb nqa 10K cov yeeb yaj kiab ntawm qib siab tshaj plaws. Qhov bandwidth tam sim no ntawm HDMI 2.0b yog 18 Gbps, thaum HDMI 2.1 yuav nce mus rau 48 Gbps, uas tuaj yeem txhawb nqa cov yeeb yaj kiab tsis zoo nrog cov kev daws teeb meem thiab cov nqi tshiab xws li 4K / 120Hz, 8K / 60Hz, thiab 10K, thiab tseem txhawb nqa HDR dynamic. Vim li no, tus qauv tshiab tau txais ib qho tshiab ultra-high-speed data cable (Ultra High Speed HDMI Cable).
