Kuyamba kwa DisplayPort, HDMI ndi Type-C Interfaces

Kuyamba kwa DisplayPort, HDMI ndi Type-C Interfaces

Pa November 29, 2017, HDMI Forum, Inc. inalengeza kutulutsidwa kwa HDMI 2.1, 48Gbps HDMI, ndi 8K HDMI mafotokozedwe, kuwapangitsa kuti apezeke kwa onse otengera HDMI 2.0. Muyezo watsopano umathandizira 10K resolution @ 120Hz (10K HDMI, 144Hz HDMI), ndi bandwidth yowonjezereka mpaka 48Gbps, ndikuyambitsa matekinoloje amphamvu a HDR ndi ma refresh rate (VRR).

Pa Julayi 26, 2017, mgwirizano wa USB 3.0 Promoter Group, wopangidwa ndi makampani aukadaulo monga Apple, HP, Intel, ndi Microsoft, adalengeza mulingo wa USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), yomwe imathandizira panjira ziwiri za 20Gbps ngati mawonekedwe osasinthika a Type-C.

Pa Marichi 3, 2016, VESA (Video Electronics Standards Association) idatulutsa mwalamulo mtundu watsopano wamtundu wotumizira ma audio-visual, DisplayPort 1.4. Mtunduwu umathandizira 8K@60Hz ndi 4K@120Hz, ndipo kwa nthawi yoyamba imaphatikiza ukadaulo wowonetsera mtsinje (DSC 1.2).

Kutulutsidwa kovomerezeka kwazomwe zasinthidwa
DisplayPort 1.4 muyezo watulutsidwa mwalamulo! Imathandizira kanema wa 60Hz 8K
Pa Marichi 1, VESA (Video Electronics Standards Association) idalengeza mwalamulo mtundu watsopano wa mawonekedwe omvera omvera a DisplayPort 1.4. Muyezo watsopanowu umakulitsanso kuthekera kotumiza makanema ndi data kudzera mu Type-C (USB C 10Gbps, 5A 100W USB C Cable), pomwe imathandizira kutumiza kwa metadata ya HDR ndikuwonjezera mawu. Muyezo watsopanowu umawonedwa ngati woyamba kusintha kwakukulu pambuyo pa kutulutsidwa kwa DisplayPort 1.3 mu Seputembara 2014.
Panthawi imodzimodziyo, iyinso ndiyeso yoyamba ya DP yomwe imathandizira teknoloji ya DSC 1.2 (Display Stream Compression). Mu mtundu wa DSC 1.2, 3: 1 kukakamiza kwamavidiyo osataya kumatha kuloledwa.

"Alternate Mode (Alt Mode)" yoperekedwa ndi DP 1.3 standard imathandizira kale kufalitsa mavidiyo ndi ma data munthawi yomweyo kudzera pa USB Type-C ndi Bingu. Pamene DP 1.4 ikupita patsogolo, kulola kuti mavidiyo odziwika bwino azitha kutumizidwa nthawi imodzi pamene SuperUSB (USB 3.0) imagwiritsidwa ntchito potumiza deta.
Kuphatikiza apo, DP 1.4 imathandizira 60Hz 8K resolution (7680 x 4320) kanema wa HDR komanso kanema wa 120Hz 4K HDR.
Zosintha zina za DP 1.4 ndi izi:
1. Forward Error Correction (FEC): Mbali ya teknoloji ya DSC 1.2, imayang'anira kulekerera koyenera kolakwika pamene mukukakamiza kanema kuti atuluke ku mawonedwe akunja.
2. Kutumiza kwa Metadata ya HDR: Pogwiritsa ntchito "paketi yachiwiri ya data" muyeso ya DP, imapereka chithandizo chamakono a CTA 861.3, omwe ndi othandiza kwambiri pa DP-HDMI 2.0a kutembenuka kwa protocol. Kuphatikiza apo, imapereka kutumiza kwa paketi ya metadata yosinthika, yothandizira tsogolo la HDR.
3. Kutumiza Kwamawu Kwawonjezeke: Izi zitha kukhudza mbali monga ma 32-bit audio channels, 1536kHz sampling rate, ndi makulidwe onse odziwika pakali pano.
VESA ikunena kuti DP 1.4 ikhala njira yabwino kwambiri yolumikizirana kuti ikwaniritse zofunikira zotumizira ma audio ndi makanema pazida zamagetsi zapamwamba kwambiri.

Cholinga cha kubadwa kwa Displayport chinali chomveka bwino - kuthetsa HDMI. Choncho, poyerekeza ndi HDMI, ilibe mawonekedwe a certification kapena malipiro a chilolezo, ndipo yasonkhanitsa makampani ambiri akuluakulu mu makampani owonetserako kuti apange bungwe la VISA kuti lipikisane ndi mgwirizano wa HDMI. Mndandandawu umaphatikizapo opanga ma chip apamwamba kwambiri komanso opanga zida zamagetsi, monga Intel, NVIDIA, AMD, Apple, Lenovo, HP, ndi zina zotero. Chifukwa chake, zitha kuwoneka momwe chiwonetsero cha Displayport chilili chowopsa. Chotsatira chomaliza cha masewerawa chimadziwika kwa onse! Kwa mawonekedwe a Displayport, chifukwa cha kusuntha koyambirira kwa mawonekedwe a HDMI, kutchuka kwa mawonekedwe a Displayport m'magawo ambiri sikunakhale koyenera. Komabe, mzimu wopitilira patsogolo wa mawonekedwe a Displayport umakumbutsanso HDMI kuti ipitilize kukula. Masewera apakati pa awiriwa apitilira mtsogolo.

Pa Novembara 28th, mkulu wa HDMI Forum adalengeza kukhazikitsidwa kwaukadaulo kwaposachedwa kwa HDMI 2.1.

Poyerekeza ndi kale, kusintha kwakukulu ndi kuwonjezeka kwakukulu kwa bandwidth, zomwe tsopano zingathe kuthandizira mavidiyo a 10K pamlingo wapamwamba kwambiri. Bandiwifi yamakono ya HDMI 2.0b ndi 18 Gbps, pamene HDMI 2.1 idzawonjezeka kufika ku 48 Gbps, yomwe ingathe kuthandizira mavidiyo osatayika ndi malingaliro ndi mitengo yotsitsimula monga 4K/120Hz, 8K/60Hz, ndi 10K, komanso imathandizira HDR yamphamvu. Pazifukwa izi, mulingo watsopanowu watengera chingwe chatsopano cha Ultra-high-speed data (Ultra High Speed HDMI Cable).
