Chiyambi cha DisplayPort, HDMI ndi Type-C Interfaces

Chiyambi cha DisplayPort, HDMI ndi Type-C Interfaces

Pa Novembala 29, 2017, HDMI Forum, Inc. idalengeza kutulutsidwa kwa ma HDMI 2.1, 48Gbps HDMI, ndi 8K HDMI, zomwe zimapangitsa kuti zigwiritsidwe ntchito ndi onse ogwiritsa ntchito HDMI 2.0. Muyezo watsopanowu umathandizira 10K resolution @ 120Hz (10K HDMI, 144Hz HDMI), pomwe bandwidth yawonjezeka kufika pa 48Gbps, ndipo imayambitsa ukadaulo wa dynamic HDR ndi variable refresh rate (VRR).

Pa Julayi 26, 2017, mgwirizano wa USB 3.0 Promoter Group, womwe umapangidwa ndi makampani aukadaulo monga Apple, HP, Intel, ndi Microsoft, udalengeza muyezo wa USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), womwe umathandizira kutumiza kwa ma 20Gbps awiri ndipo umalimbikitsa Type-C ngati mawonekedwe ogwirizana.

Pa 3 Marichi, 2016, VESA (Video Electronics Standards Association) idatulutsa mwalamulo mtundu watsopano wa muyezo wotumizira mawu ndi zithunzi, DisplayPort 1.4. Mtundu uwu umathandizira 8K@60Hz ndi 4K@120Hz, ndipo kwa nthawi yoyamba ikuphatikiza ukadaulo wochepetsera kufalikira kwa chiwonetsero (DSC 1.2).

Kutulutsidwa kovomerezeka kwa miyezo yatsopano kukuyembekezeka
Muyezo wa DisplayPort 1.4 watulutsidwa mwalamulo! Umathandizira kanema wa 60Hz 8K
Pa 1 Marichi, VESA (Video Electronics Standards Association) idalengeza mwalamulo mtundu watsopano wa muyezo wotumizira mawu ndi zithunzi wa DisplayPort 1.4. Muyezo watsopanowu ukuwonjezeranso kuthekera kotumizira makanema ndi deta kudzera mu Type-C (USB C 10Gbps, 5A 100W USB C Cable), pomwe ikuthandizira kutumiza metadata ya HDR ndi ma specifications owonjezera a mawu. Muyezo watsopanowu umaonedwa ngati kusintha koyamba kwakukulu pambuyo pa kutulutsidwa kwa DisplayPort 1.3 mu Seputembala 2014.
Nthawi yomweyo, iyi ndi muyezo woyamba wa DP womwe umathandizira ukadaulo wa DSC 1.2 (Display Stream Compression). Mu mtundu wa DSC 1.2, kukanikiza makanema opanda kutayika kwa 3:1 kungaloledwe.

"Njira Yosinthira (Alt Mode)" yoperekedwa ndi muyezo wa DP 1.3 imathandizira kale kutumiza makanema ndi deta nthawi imodzi kudzera pa USB Type-C ndi Thunderbolt interfaces. Ngakhale DP 1.4 ikupita patsogolo, kulola kutumiza makanema apamwamba nthawi imodzi pomwe SuperUSB (USB 3.0) imagwiritsidwa ntchito potumiza deta.
Kuphatikiza apo, DP 1.4 ithandizira kanema wa 60Hz 8K resolution (7680 x 4320) HDR komanso kanema wa 120Hz 4K HDR.
Zosintha zina za DP 1.4 ndi izi:
1. Kukonza Zolakwika Patsogolo (FEC): Ndi gawo la ukadaulo wa DSC 1.2, umathandiza kuthana ndi vuto poika kanema kuti atulutse zowonetsera zakunja.
2. Kutumiza kwa HDR Metadata: Pogwiritsa ntchito "paketi yachiwiri ya data" mu muyezo wa DP, imapereka chithandizo cha muyezo wa CTA 861.3 womwe ulipo, womwe ndi wothandiza kwambiri pa protocol ya kusintha kwa DP-HDMI 2.0a. Kuphatikiza apo, imapereka kutumiza kwa metadata pack yosinthika kwambiri, kuthandizira HDR yosinthika yamtsogolo.
3. Kutumiza Kwamawu Kowonjezereka: Izi zitha kuphimba zinthu monga njira zamawu za 32-bit, kuchuluka kwa zitsanzo za 1536kHz, ndi mitundu yonse yamawu yodziwika pakadali pano.
VESA ikunena kuti DP 1.4 idzakhala muyezo woyenera kwambiri wolumikizirana kuti ikwaniritse zofunikira zapamwamba kwambiri zotumizira mawu ndi makanema pazida zamagetsi zapamwamba.

Cholinga cha kubadwa kwa Displayport chinali chodziwikiratu - kuchotsa HDMI. Chifukwa chake, poyerekeza ndi HDMI, ilibe satifiketi ya interface kapena ndalama zolipirira ufulu wa olemba, ndipo yasonkhanitsa makampani ambiri akuluakulu mumakampani owonetsera kuti apange bungwe la VISA kuti lipikisane ndi bungwe la HDMI. Mndandandawu ukuphatikizapo opanga ma chip apamwamba ambiri ndi opanga zida zamagetsi, monga Intel, NVIDIA, AMD, Apple, Lenovo, HP, ndi ena otero. Chifukwa chake, zitha kuwoneka momwe Displayport ilili yolimba. Zotsatira zomaliza zamasewerawa zimadziwika ndi aliyense! Pa mawonekedwe a Displayport, chifukwa cha kusuntha koyambirira kwa mawonekedwe a HDMI, mphamvu yodziwika bwino ya mawonekedwe a Displayport m'magawo ambiri sinali yabwino. Komabe, mzimu wopitilira patsogolo wa mawonekedwe a Displayport umakumbutsanso HDMI kuti ipitirire kukula. Masewera pakati pa awiriwa apitiliza mtsogolo.

Pa 28 Novembala, mkulu wa HDMI Forum adalengeza kukhazikitsidwa mwalamulo kwa muyezo waposachedwa waukadaulo wa HDMI 2.1.

Poyerekeza ndi kale, kusintha kwakukulu kwambiri ndi kuwonjezeka kwakukulu kwa bandwidth, komwe tsopano kungathe kuthandizira makanema a 10K pamlingo wapamwamba kwambiri. HDMI 2.0b yomwe ilipo pano ndi 18 Gbps, pomwe HDMI 2.1 idzakwera kufika pa 48 Gbps, yomwe ingathe kuthandizira makanema opanda kutayika okhala ndi ma resolution ndi ma refresh rate monga 4K/120Hz, 8K/60Hz, ndi 10K, komanso kuthandizira dynamic HDR. Pachifukwa ichi, muyezo watsopano wagwiritsa ntchito chingwe chatsopano cha data chothamanga kwambiri (Ultra High Speed ​​​​HDMI Cable).
