Intangiriro kuri DisplayPort, HDMI na Type-C Imigaragarire

Intangiriro kuri DisplayPort, HDMI na Type-C Imigaragarire

Ku ya 29 Ugushyingo 2017, Ihuriro rya HDMI, Inc. ryatangaje ko hasohotse HDMI 2.1, 48Gbps HDMI, na 8K HDMI, bigatuma abantu bose babakoresha HDMI 2.0. Igipimo gishya gishyigikira 10K imyanzuro @ 120Hz (10K HDMI, 144Hz HDMI), hamwe n'umuyoboro mugari wiyongereye kugera kuri 48Gbps, kandi utangiza imbaraga za HDR hamwe na tekinoroji yo kugarura ibintu (VRR).

Ku ya 26 Nyakanga 2017, ihuriro rya USB 3.0 Promoter Group, rigizwe n’amasosiyete y’ikoranabuhanga nka Apple, HP, Intel, na Microsoft, ryatangaje USB 3.2 isanzwe (USB 3.1 C TO C, USB C 10Gbps, Ubwoko C Umugabo kugeza ku mugabo), ishyigikira imiyoboro ibiri ya 20Gbps kandi ikanasaba Ubwoko-C nk'imikoranire ihuriweho.

Ku ya 3 Werurwe 2016, VESA (Video Electronics Standard Association Association) yasohoye kumugaragaro verisiyo nshya yuburyo bwo kohereza amajwi n'amashusho, DisplayPort 1.4. Iyi verisiyo ishyigikira 8K @ 60Hz na 4K @ 120Hz, kandi kunshuro yambere ihuza tekinoroji yo kwerekana amashanyarazi (DSC 1.2).

Biteganijwe ko hasohoka kumugaragaro ibipimo bigezweho
DisplayPort 1.4 isanzwe yasohotse kumugaragaro! Shyigikira amashusho ya 60Hz 8K
Ku ya 1 Werurwe, VESA (Video Electronics Standard Association Association) yatangaje ku mugaragaro verisiyo nshya yuburyo bwo kohereza amajwi n'amashusho DisplayPort 1.4. Ibipimo bishya birusheho kunoza ubushobozi bwo kohereza amashusho namakuru binyuze muri Type-C (USB C 10Gbps, 5A 100W USB C Cable), mugihe ushyigikiye HDR metadata no kwagura amajwi. Ibipimo bishya bifatwa nkibintu byambere byingenzi nyuma yo gusohora DisplayPort 1.3 muri Nzeri 2014.
Mugihe kimwe, iyi nayo niyo DP yambere yambere ishyigikira tekinoroji ya DSC 1.2 (Erekana Stream Compression). Muri verisiyo ya DSC 1.2, 3: 1 igabanuka rya videwo yerekana amashusho irashobora kwemerwa.

"Ubundi buryo (Alt Mode)" butangwa na DP 1.3 isanzwe ishyigikira icyarimwe icyarimwe cyohereza amashusho na data ukoresheje USB Type-C na Thunderbolt. Mugihe DP 1.4 itera indi ntera, yemerera kohereza icyarimwe amashusho asobanutse mugihe SuperUSB (USB 3.0) ikoreshwa mugutanga amakuru.
Mubyongeyeho, DP 1.4 izashyigikira amashusho ya 60Hz 8K (7680 x 4320) HDR hamwe na 120Hz 4K HDR.
Ibindi bishya bya DP 1.4 nibi bikurikira:
1. Gukosora Amakosa Yimbere (FEC): Igice cyubuhanga bwa DSC 1.2, gikemura ikibazo gikwiye cyo kwihanganira amakosa mugihe cyo gukuramo amashusho kugirango asohoke yerekanwe hanze.
2. Ikwirakwizwa rya HDR Metadata: Ukoresheje "data packet ya kabiri" murwego rwa DP, itanga inkunga kubisanzwe CTA 861.3 isanzwe, ifite akamaro kanini kuri protocole ya DP-HDMI 2.0a. Byongeye kandi, itanga uburyo bworoshye bwo guhinduranya paki ya metadata, igafasha HDR izaza.
3. Kwagura amajwi yagutse: Ibi bisobanuro birashobora gukubiyemo ibintu nkumuyoboro wamajwi 32-bit, igipimo cyicyitegererezo cya 1536kHz, nuburyo bwose buzwi bwamajwi.
VESA ivuga ko DP 1.4 izahinduka uburyo bwiza bwo guhuza ibipimo byujuje ubuziranenge bwogukwirakwiza amajwi n'amashusho y'ibikoresho bya elegitoroniki yo mu rwego rwo hejuru.

Intego yo kuvuka kwa Displayport yari isobanutse neza - gukuraho HDMI. Kubwibyo, ugereranije na HDMI, ntabwo ifite icyemezo cyimbere cyangwa amafaranga yuburenganzira, kandi yakusanyije umubare munini wibigo bikomeye mu nganda zerekana kwerekana ishyirahamwe VISA kugirango rihangane n’ishyirahamwe rya HDMI. Urutonde rurimo abakora chip nyinshi zo murwego rwohejuru hamwe nabakora ibikoresho bya elegitoronike, nka Intel, NVIDIA, AMD, Apple, Lenovo, HP, nibindi. Rero, birashobora kugaragara uburyo imbaraga za Displayport zikaze. Ibisubizo byanyuma byumukino birazwi na bose! Kuri Interineti ya Displayport, kubera kwimuka mbere yimbere ya HDMI, ingaruka zo kumenyekanisha interineti ya Displayport mubice byinshi ntabwo byari byiza. Ariko, umwuka uhoraho witerambere ryimikorere ya Displayport nayo yibutsa HDMI gukomeza gutera imbere. Umukino uzahuza bombi uzakomeza ejo hazaza.

Ku ya 28 Ugushyingo, umuyobozi w'ihuriro rya HDMI yatangaje ko hatangijwe ku mugaragaro ibipimo bya tekiniki bya HDMI 2.1 bigezweho.

Ugereranije na mbere, impinduka zikomeye nukwiyongera gutangaje kwagutse, ubu ishobora gushyigikira amashusho 10K kurwego rwo hejuru. Umuyoboro mugari wa HDMI 2.0b ni 18 Gbps, mugihe HDMI 2.1 iziyongera kugera kuri 48 Gbps, ishobora gushyigikira byimazeyo amashusho atagira igihombo hamwe nicyemezo no kugarura ibiciro nka 4K / 120Hz, 8K / 60Hz, na 10K, kandi ikanashyigikira HDR ifite imbaraga. Kubera iyo mpamvu, igipimo gishya cyakoresheje insinga nshya ya ultra-yihuta yihuta ya kabili (Ultra High Speed HDMI Cable).
