Intangiriro kuri DisplayPort, HDMI na Interfaces za Type-C

Intangiriro kuri DisplayPort, HDMI na Interfaces za Type-C

Ku ya 29 Ugushyingo 2017, HDMI Forum, Inc. yatangaje ko hasohotse HDMI 2.1, 48Gbps HDMI, na 8K HDMI, bituma ziboneka ku bakoresha HDMI 2.0 bose. Iyi gahunda nshya ishyigikira ubushobozi bwa 10K kuri 120Hz (10K HDMI, 144Hz HDMI), aho bandwidth yongerewe igera kuri 48Gbps, kandi izana ikoranabuhanga rya HDR rihindagurika na ikoranabuhanga rya VRR.

Ku ya 26 Nyakanga 2017, itsinda rya USB 3.0 Promoter Group, rigizwe n’ibigo by’ikoranabuhanga nka Apple, HP, Intel, na Microsoft, ryatangaje uburyo bwa USB 3.2 busanzwe (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), bushyigikira uburyo bwo kohereza ubutumwa bwa 20Gbps mu buryo bubiri kandi bugasaba Type-C nk'uburyo buhuriweho.

Ku ya 3 Werurwe 2016, VESA (Ishyirahamwe ry’Ibipimo by’Ikoranabuhanga rya Video Electronics) ryashyize ahagaragara ku mugaragaro verisiyo nshya y’uburyo bwo kohereza amajwi n’amashusho, DisplayPort 1.4. Iyi verisiyo ishyigikira 8K@60Hz na 4K@120Hz, kandi ku nshuro ya mbere ihuza ikoranabuhanga ryo gukanda imirasire y’amajwi (DSC 1.2).

Itangazo ryemewe ry’amahame mashya riteganijwe
DisplayPort 1.4 isanzwe yasohotse ku mugaragaro! Ifite ubushobozi bwo gukoresha videwo ya 60Hz 8K
Ku ya 1 Werurwe, VESA (Ishyirahamwe ry’Ibipimo by’Ikoranabuhanga rya Video) ryatangaje ku mugaragaro verisiyo nshya y’uburyo bwo kohereza amajwi n’amashusho bwa DisplayPort 1.4. Ubu buryo bushya bwo kohereza amashusho n’amakuru binyuze mu bwoko bwa Type-C (USB C 10Gbps, 5A 100W USB C Cable), mu gihe bushyigikira uburyo bwo kohereza amakuru ya HDR n’uburyo bwo kongera amajwi. Ubu buryo bushya bufatwa nk’ivugurura rya mbere rikomeye nyuma yo gusohora DisplayPort 1.3 muri Nzeri 2014.
Muri icyo gihe, iyi ni yo DP ya mbere ikoreshwa mu ikoranabuhanga rya DSC 1.2 (Display Stream Compression). Muri verisiyo ya DSC 1.2, gukanda amashusho ya videwo nta gutakaza 3:1 birashobora kwemerwa.

"Uburyo Bunyuranye (Alt Mode)" butangwa n'urwego rwa DP 1.3 busanzwe bufasha kohereza amashusho n'amakuru icyarimwe binyuze kuri USB Type-C na Thunderbolt interfaces. Mu gihe DP 1.4 itera intambwe irenga, ituma kohereza amashusho mu buryo bworoshye icyarimwe mu gihe SuperUSB (USB 3.0) ikoreshwa mu kohereza amakuru.
Byongeye kandi, DP 1.4 izashyigikira videwo ya HDR ya 60Hz ifite ubushobozi bwo kureba 8K (7680 x 4320) ndetse na videwo ya HDR ya 120Hz ifite ubushobozi bwo kureba 4K.
Izindi nyandiko nshya za DP 1.4 ni izi zikurikira:
1. Gukosora amakosa yo mu gihe cyo gusohora amashusho (FEC): Ni igice cy'ikoranabuhanga rya DSC 1.2, rikemura ikibazo cyo kwihanganira amakosa mu gihe cyo gukanda videwo kugira ngo ijye ahagaragara amashusho yo hanze.
2. Kohereza amakuru kuri HDR: Ikoresheje "paketi y'amakuru y'inyongera" mu gipimo cya DP, itanga inkunga ku gipimo cya CTA 861.3 kiriho ubu, bikaba ingirakamaro cyane kuri protocole yo guhindura amakuru ya DP-HDMI 2.0a. Byongeye kandi, itanga uburyo bworoshye bwo kohereza amakuru kuri pakiti ya metadata, ishyigikira HDR ihinduka mu gihe kizaza.
3. Kwagura Amajwi: Ibi bisobanuro bishobora gukubiyemo ibintu nka chaneli z'amajwi za biti 32, igipimo cyo gupima 1536kHz, n'imiterere yose y'amajwi izwi muri iki gihe.
VESA ivuga ko DP 1.4 izaba ari yo ikoreshwa neza cyane mu guhuza amajwi n'amashusho kugira ngo ihuze n'ibisabwa mu buryo bwiza bwo kohereza amajwi n'amashusho ku bikoresho by'ikoranabuhanga bigezweho.

Intego y'ivuka rya Displayport yari isobanutse neza - gukuraho HDMI. Kubwibyo, ugereranije na HDMI, nta cyemezo cya interface cyangwa amafaranga y'uburenganzira bw'umwanditsi ifite, kandi yakusanyije umubare munini w'amasosiyete akomeye mu nganda zo kwerekana amashusho kugira ngo ashinge ishyirahamwe rya VISA kugira ngo ahangane n'ishyirahamwe rya HDMI. Urutonde rurimo abakora chips nyinshi zo ku rwego rwo hejuru n'inganda zikora ibikoresho by'ikoranabuhanga, nka Intel, NVIDIA, AMD, Apple, Lenovo, HP, n'abandi. Bityo, biragaragara ukuntu Displayport ikomeye cyane. Umusaruro wa nyuma w'umukino uzwi na bose! Ku bijyanye na Displayport, bitewe n'impinduka za HDMI, ingaruka zo kwamamaza za Displayport mu nzego nyinshi ntizari nziza. Ariko, umwuka wo gukomeza iterambere wa Displayport unakwibutsa HDMI gukomeza gutera imbere. Umukino hagati y'izo ebyiri uzakomeza mu gihe kizaza.

Ku itariki ya 28 Ugushyingo, umukozi wa HDMI Forum yatangaje ko yatangije ku mugaragaro uburyo bushya bwa tekiniki bwa HDMI 2.1.

Ugereranyije na mbere, impinduka ikomeye cyane ni ukwiyongera gukomeye kwa bandwidth, ubu ishobora gushyigikira videwo 10K ku rwego rwo hejuru. HDMI 2.0b ubu ni 18 Gbps, mu gihe HDMI 2.1 iziyongera ikagera kuri 48 Gbps, ishobora gushyigikira videwo zidafite igihombo hamwe n’ibipimo byo kuvugurura nka 4K/120Hz, 8K/60Hz, na 10K, ndetse inashyigikira HDR ihindagurika. Kubera iyo mpamvu, ubu buryo bushya bwakoresheje insinga nshya y’amakuru yihuta cyane (Ultra High Speed ​​HDMI Cable).
