Isingeniso ku-DisplayPort, i-HDMI nezixhumi ezibonakalayo zohlobo C
Ngomhla zingama-29 kuNovemba 2017, i-HDMI Forum, Inc. imemezele ukukhishwa kwe-HDMI 2.1, 48Gbps HDMI, kanye nokucaciswa kwe-8K HDMI, okwenza kutholakale kubo bonke abamukeli be-HDMI 2.0. Izinga elisha lisekela ukulungiswa kwe-10K @ 120Hz (10K HDMI, 144Hz HDMI), nomkhawulokudonsa okhushulelwe ku-48Gbps, futhi wethula ubuchwepheshe be-HDR obuguquguqukayo kanye nesilinganiso sokuvuselela (VRR).
Ngomhla zingama-26 kuJulayi 2017, umfelandawonye we-USB 3.0 Promoter Group, ohlanganisa izinkampani zobuchwepheshe ezifana ne-Apple, HP, Intel, ne-Microsoft, umemezele izinga le-USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), esekela i-dual-channel 20Gbps-C interface njengesixhumi esibonakalayo esingaguquki.
NgoMashi 3, 2016, i-VESA (Video Electronics Standards Association) ikhiphe ngokusemthethweni inguqulo entsha yezinga lokudlulisa umsindo nokubukwayo, i-DisplayPort 1.4. Le nguqulo isekela i-8K@60Hz kanye ne-4K@120Hz, futhi ngokokuqala ngqa ihlanganisa ubuchwepheshe bokucindezela ukusakaza kokusakaza (DSC 1.2).

Ukukhishwa okusemthethweni okulindelekile kwamazinga abuyekeziwe
I-DisplayPort 1.4 ejwayelekile ikhishwe ngokusemthethweni! Isekela ividiyo engu-60Hz 8K
NgoMashi 1st, i-VESA (I-Video Electronics Standards Association) yamemezela ngokusemthethweni inguqulo entsha ye-DisplayPort 1.4 ejwayelekile yokudlulisa umsindo nokubukwayo. Izinga elisha lithuthukisa futhi amandla okudlulisa ividiyo nedatha ngo-Type-C (USB C 10Gbps, 5A 100W USB C Cable), kuyilapho isekela ukudluliswa kwemethadatha ye-HDR kanye nokucaciswa komsindo okunwetshiwe. Izinga elisha lithathwa njengesibuyekezo sokuqala esikhulu ngemuva kokukhishwa kwe-DisplayPort 1.3 ngoSepthemba 2014.
Ngesikhathi esifanayo, leli futhi izinga lokuqala le-DP elisekela ubuchwepheshe be-DSC 1.2 (Display Stream Compression). Kunguqulo ye-DSC 1.2, ukucindezela kokusakaza kwevidiyo okungu-3:1 okungalahleki kungavunyelwa.
“Enye Imodi (Imodi Ye-Alt)” ehlinzekwa ngezinga le-DP 1.3 isivele isekela ukudluliswa kanyekanye kwevidiyo nokusakaza kwedatha nge-USB Type-C ne-Thunderbolt interface. Nakuba i-DP 1.4 ithatha igxathu eliya phambili, ivumela ukudluliswa ngesikhathi esisodwa kwevidiyo enencazelo ephezulu kuyilapho i-SuperUSB (USB 3.0) isetshenziselwa ukudluliswa kwedatha.
Ngaphezu kwalokho, i-DP 1.4 izosekela ukulungiswa kwe-60Hz 8K (7680 x 4320) ividiyo ye-HDR kanye nevidiyo engu-120Hz 4K HDR.
Ezinye izibuyekezo ze-DP 1.4 zimi kanje:
1. Ukulungiswa Kwephutha Langaphambili (i-FEC): Ingxenye yobuchwepheshe be-DSC 1.2, ibhekana nokubekezelela iphutha okufanele lapho ucindezela ividiyo ukuze ikhishwe ezibukweni zangaphandle.
2. Ukudluliselwa Kwemethadatha ye-HDR: Ngokusebenzisa “iphakethe ledatha lesibili” ezingeni le-DP, linikeza ukusekelwa kwezinga lamanje le-CTA 861.3, eliwusizo kakhulu kuphrothokholi yokuguqulwa kwe-DP-HDMI 2.0a. Ukwengeza, ihlinzeka ngokudluliswa kwephakethe lemethadatha evumelana nezimo, isekela i-HDR eguquguqukayo yesikhathi esizayo.
3. Ukudluliswa Komsindo Okunwetshiwe: Lokhu kucaciswa kungafaka izici ezifana namashaneli omsindo angama-32-bit, izinga lamasampula angu-1536kHz, nawo wonke amafomethi omsindo aziwayo okwamanje.
I-VESA ithi i-DP 1.4 izoba indinganiso yesixhumi esibonakalayo efanelekile kakhulu ukuze ihlangabezane nezidingo zokudlulisa umsindo nevidiyo ezisezingeni eliphezulu zemishini kagesi esezingeni eliphezulu.
Inhloso yokuzalwa kwe-Displayport yayicacile - ukuqeda i-HDMI. Ngakho-ke, uma kuqhathaniswa ne-HDMI, ayinaso isitifiketi sokusebenzisana noma izimali ze-copyright, futhi iqoqe inombolo enkulu yezinkampani ezinkulu embonini yokubonisa ukuze zenze inhlangano ye-VISA ukuncintisana ngokumelene nenhlangano ye-HDMI. Uhlu luhlanganisa abakhiqizi abaningi be-chip abasezingeni eliphezulu nabakhiqizi bemishini kagesi, njenge-Intel, NVIDIA, AMD, Apple, Lenovo, HP, njalonjalo. Ngakho-ke, kuyabonakala ukuthi umfutho we-Displayport ushube kangakanani. Umphumela wokugcina womdlalo waziwa yibo bonke! Ku-interface ye-Displayport, ngenxa yomnyakazo wokuqala wesixhumi esibonakalayo se-HDMI, umthelela wodumo wesixhumi esibonakalayo se-Displayport emikhakheni eminingi awuzange ulunge. Kodwa-ke, umoya wokuthuthuka oqhubekayo wesixhumi esibonakalayo se-Displayport uphinde ukhumbuze i-HDMI ukuthi iqhubeke nokuthuthuka. Umdlalo phakathi kwalaba ababili uzoqhubeka esikhathini esizayo.
Ngomhla zingama-28 kuNovemba, isikhulu se-HDMI Forum simemezele ukwethulwa okusemthethweni kwezinga lobuchwepheshe lakamuva le-HDMI 2.1.
Uma kuqhathaniswa nangaphambili, ushintsho olubaluleke kakhulu ukwanda okumangalisayo komkhawulokudonsa, manje ongasekela amavidiyo angu-10K ezingeni eliphezulu kakhulu. Umkhawulokudonsa wamanje we-HDMI 2.0b ngu-18 Gbps, kuyilapho i-HDMI 2.1 izokhuphuka ibe ngu-48 Gbps, engasekela ngokugcwele amavidiyo angalahleki anesinqumo namazinga okuvuselela afana no-4K/120Hz, 8K/60Hz, kanye no-10K, futhi isekela i-HDR enamandla. Ngalesi sizathu, izinga elisha lamukele ikhebuli yedatha ye-ultra-high-speed (Ikhebula le-Ultra High Speed HDMI).
Isikhathi sokuthumela: Jul-28-2025
