Isingeniso ku-DisplayPort, i-HDMI kanye ne-Type-C Interfaces

Ngomhlaka-29 Novemba 2017, i-HDMI Forum, Inc. yamemezela ukukhishwa kwemininingwane ye-HDMI 2.1, 48Gbps HDMI, kanye ne-8K HDMI, okwenza ukuthi itholakale kubo bonke abasebenzisa i-HDMI 2.0. Indinganiso entsha isekela isinqumo se-10K @ 120Hz (10K HDMI, 144Hz HDMI), kanye ne-bandwidth ekhuliswe yaba yi-48Gbps, futhi yethula ubuchwepheshe be-HDR enamandla kanye ne-variable refresh rate (VRR).

Ngomhlaka-26 kuJulayi 2017, i-alliance ye-USB 3.0 Promoter Group, ehlanganisa izinkampani zobuchwepheshe ezifana ne-Apple, i-HP, i-Intel, ne-Microsoft, yamemezela indinganiso ye-USB 3.2 (i-USB 3.1 C TO C, i-USB C 10Gbps, i-Type C Male TO Male), esekela ukudluliswa kwe-20Gbps enamachaneli amabili futhi incoma i-Type-C njengesixhumi esihlanganisiwe.

NgoMashi 3, 2016, i-VESA (Video Electronics Standards Association) ikhiphe ngokusemthethweni inguqulo entsha yendinganiso yokudlulisa umsindo nokubukwayo, i-DisplayPort 1.4. Le nguqulo isekela i-8K@60Hz kanye ne-4K@120Hz, futhi okokuqala ihlanganisa ubuchwepheshe bokucindezela ukusakaza kokubonisa (DSC 1.2).

Ukukhishwa okusemthethweni okulindelekile kwezindinganiso ezibuyekeziwe
I-DisplayPort 1.4 ejwayelekile ikhishwe ngokusemthethweni! Isekela ividiyo engu-60Hz 8K
Ngomhlaka-1 kuNdasa, i-VESA (Video Electronics Standards Association) yamemezela ngokusemthethweni inguqulo entsha yendinganiso yokudlulisa umsindo nokubukwayo i-DisplayPort 1.4. Indinganiso entsha ithuthukisa ikhono lokudlulisa ividiyo nedatha nge-Type-C (USB C 10Gbps, 5A 100W USB C Cable), ngenkathi isekela ukudluliselwa kwe-metadata ye-HDR kanye nokucaciswa komsindo okweluliwe. Indinganiso entsha ibhekwa njengesibuyekezo sokuqala esikhulu ngemuva kokukhishwa kwe-DisplayPort 1.3 ngoSepthemba 2014.
Ngesikhathi esifanayo, lokhu futhi kuyindinganiso yokuqala ye-DP esekela ubuchwepheshe be-DSC 1.2 (Display Stream Compression). Kuhlobo lwe-DSC 1.2, ukucindezelwa kokusakaza kwevidiyo okungenalahleko okungu-3:1 kungavunyelwa.

I-“Alternate Mode (Alt Mode)” enikezwa yi-DP 1.3 standard isivele isekela ukudluliswa kwevidiyo kanye nedatha ngasikhathi sinye ngokusebenzisa i-USB Type-C kanye ne-Thunderbolt interfaces. Ngenkathi i-DP 1.4 ithatha isinyathelo esengeziwe, ivumela ukudluliswa kwevidiyo ephezulu ngasikhathi sinye kuyilapho i-SuperUSB (USB 3.0) isetshenziselwa ukudluliswa kwedatha.
Ngaphezu kwalokho, i-DP 1.4 izosekela ividiyo ye-HDR engu-60Hz enesisombululo esingu-8K (7680 x 4320) kanye nevidiyo ye-HDR engu-120Hz ene-4K.
Ezinye izibuyekezo ze-DP 1.4 zimi kanje:
1. Ukulungiswa Kwephutha Lokudlulisela (FEC): Ingxenye yobuchwepheshe be-DSC 1.2, ibhekana nokubekezelela amaphutha okufanele lapho icindezela ividiyo ukuze ikhishwe ezikrinini zangaphandle.
2. Ukudluliswa kwe-HDR Metadata: Ngokusebenzisa “iphakethe ledatha lesibili” ku-DP standard, inikeza ukwesekwa kwe-CTA 861.3 standard yamanje, okuwusizo kakhulu kuphrothokholi yokuguqulwa kwe-DP-HDMI 2.0a. Ngaphezu kwalokho, inikeza ukudluliswa kwephakethe le-metadata okuguquguqukayo kakhudlwana, okusekela i-HDR enamandla yesikhathi esizayo.
3. Ukudluliselwa Komsindo Okunwetshiwe: Le ncazelo ingahlanganisa izici ezifana neziteshi zomsindo ezingama-32-bit, izinga lokusampula elingu-1536kHz, kanye nazo zonke izinhlobo zomsindo ezaziwayo okwamanje.
I-VESA ithi i-DP 1.4 izoba yindinganiso yesixhumi esibonakalayo efanelekile kakhulu ukuhlangabezana nezidingo zokudlulisa umsindo nevidiyo ezisezingeni eliphezulu zamadivayisi kagesi asezingeni eliphezulu.

Inhloso yokuzalwa kweDisplayport yayicacile impela - ukuqeda i-HDMI. Ngakho-ke, uma iqhathaniswa ne-HDMI, ayinazo iziqinisekiso zesikhombimsebenzisi noma izimali ze-copyright, futhi iqoqe inani elikhulu lezinkampani ezinkulu embonini yokubonisa ukuze zakhe inhlangano ye-VISA ukuze incintisane nenhlangano ye-HDMI. Uhlu luhlanganisa abakhiqizi abaningi be-chip abasezingeni eliphezulu kanye nabakhiqizi bemishini kagesi, njenge-Intel, i-NVIDIA, i-AMD, i-Apple, i-Lenovo, i-HP, njalo njalo. Ngakho-ke, kungabonakala ukuthi umfutho weDisplayport unamandla kangakanani. Umphumela wokugcina womdlalo waziwa yibo bonke! Ngesikhombimsebenzisi seDisplayport, ngenxa yokunyakaza kokulungiselela kwesikhombimsebenzisi se-HDMI, umphumela wokwanda kwesikhombimsebenzisi seDisplayport emikhakheni eminingi awuzange ube muhle. Kodwa-ke, umoya wokuqhubeka okuqhubekayo wesikhombimsebenzisi seDisplayport uphinde ukhumbuze i-HDMI ukuthi iqhubeke nokukhula. Umdlalo phakathi kwalaba ababili uzoqhubeka esikhathini esizayo.

Ngomhlaka-28 Novemba, isikhulu se-HDMI Forum samemezela ukwethulwa ngokusemthethweni kwendinganiso yobuchwepheshe yakamuva ye-HDMI 2.1.

Uma kuqhathaniswa nangaphambili, ushintsho olubaluleke kakhulu ukwanda okukhulu komkhawulokudonsa, manje ongasekela amavidiyo angu-10K ezingeni eliphezulu kakhulu. Umkhawulokudonsa wamanje we-HDMI 2.0b ungu-18 Gbps, kanti i-HDMI 2.1 izokhuphuka ibe ngu-48 Gbps, engasekela ngokugcwele amavidiyo angenakulahlekelwa ngama-resolution kanye namazinga okuvuselela njenge-4K/120Hz, 8K/60Hz, kanye ne-10K, futhi isekele i-dynamic HDR. Ngenxa yalesi sizathu, indinganiso entsha isebenzise ikhebula elisha ledatha elisheshayo kakhulu (i-Ultra High Speed ​​​​HDMI Cable).
