Intshayelelo kwi-DisplayPort, i-HDMI kunye ne-Type-C Interfaces

Ngomhla wama-29 kweyeNkanga, ngo-2017, i-HDMI Forum, Inc. yabhengeza ukukhutshwa kweenkcukacha ze-HDMI 2.1, i-48Gbps HDMI, kunye ne-8K HDMI, nto leyo eyenza ukuba zifumaneke kubo bonke abasebenzisa i-HDMI 2.0. Lo mgangatho mtsha uxhasa isisombululo se-10K @ 120Hz (10K HDMI, 144Hz HDMI), kunye ne-bandwidth eyandisiweyo ukuya kwi-48Gbps, kwaye yazisa ubuchwepheshe be-HDR eguquguqukayo kunye ne-variable refresh rate (VRR).

Ngomhla wama-26 kuJulayi, ngo-2017, i-USB 3.0 Promoter Group alliance, equka iinkampani zobuchwepheshe ezifana ne-Apple, i-HP, i-Intel, kunye ne-Microsoft, yabhengeza umgangatho we-USB 3.2 (i-USB 3.1 C TO C, i-USB C 10Gbps, i-Type C Male TO Male), exhasa ukuhanjiswa kwe-20Gbps ye-dual-channel kwaye icebisa i-Type-C njengonxibelelwano oludibeneyo.

Ngomhla wesi-3 kweyoKwindla, ngo-2016, iVESA (Video Electronics Standards Association) ikhuphe ngokusesikweni inguqulelo entsha yomgangatho wokusasazwa kwesandi nomboniso, iDisplayPort 1.4. Le nguqulelo ixhasa i-8K@60Hz kunye ne-4K@120Hz, kwaye okokuqala idibanisa itekhnoloji yokucinezela umlambo wokubonisa (DSC 1.2).

Ukukhutshwa okusemthethweni okulindelweyo kwemigangatho ehlaziyiweyo
I-DisplayPort 1.4 esemgangathweni ikhutshwe ngokusesikweni! Ixhasa ividiyo ye-60Hz 8K
Ngomhla woku-1 kweyoKwindla, iVESA (iVideo Electronics Standards Association) yabhengeza ngokusesikweni inguqulelo entsha yomgangatho wokudlulisa isandi-nembonakalo iDisplayPort 1.4. Lo mgangatho mtsha uphucula ngakumbi amandla okudlulisa ividiyo kunye nedatha ngeType-C (USB C 10Gbps, 5A 100W USB C Cable), ngelixa ixhasa ukuhanjiswa kwemetadata ye-HDR kunye neenkcukacha zomsindo ezandisiweyo. Lo mgangatho mtsha uthathwa njengohlaziyo lokuqala olukhulu emva kokukhutshwa kweDisplayPort 1.3 ngoSeptemba 2014.
Kwangaxeshanye, le ikwangumgangatho wokuqala we-DP oxhasa itekhnoloji ye-DSC 1.2 (Display Stream Compression). Kwinguqulelo ye-DSC 1.2, ukucinezelwa kwevidiyo engenalahleko ye-3:1 kunokuvunyelwa.

I-“Alternate Mode (Alt Mode)” enikezelwa ngumgangatho we-DP 1.3 sele ixhasa ukuhanjiswa kwevidiyo kunye nedatha ngaxeshanye nge-USB Type-C kunye ne-Thunderbolt interfaces. Ngelixa i-DP 1.4 ithatha inyathelo eliya phambili, ivumela ukuhanjiswa kwevidiyo ephezulu ngaxeshanye ngelixa i-SuperUSB (USB 3.0) isetyenziselwa ukuhanjiswa kwedatha.
Ukongeza, i-DP 1.4 iya kuxhasa ividiyo ye-60Hz yesisombululo se-8K (7680 x 4320) se-HDR kunye nevidiyo ye-120Hz ye-4K HDR.
Olunye uhlaziyo lwe-DP 1.4 lulandelayo:
1. Ukulungiswa Kwempazamo Eyaphambili (FEC): Inxalenye yetekhnoloji ye-DSC 1.2, ijongana nokunyamezela iimpazamo ezifanelekileyo xa ucinezela ividiyo ukuze iphume kwiimboniso zangaphandle.
2. Ukuhanjiswa kweMetadata ye-HDR: Ngokusebenzisa "iphakheji yedatha yesibini" kumgangatho we-DP, inika inkxaso kumgangatho wangoku we-CTA 861.3, oluncedo kakhulu kwiprotocol yokuguqulwa kwe-DP-HDMI 2.0a. Ukongeza, inika ukuhanjiswa kwepakethi yemetadata eguquguqukayo ngakumbi, ixhasa i-HDR enamandla yexesha elizayo.
3. Ukuhanjiswa kwesandi okwandisiweyo: Olu lwazi lunokugubungela iinkalo ezifana neetshaneli zesandi ezingama-32-bit, izinga lokuvavanya isampuli le-1536kHz, kunye nazo zonke iifomathi zesandi ezaziwayo okwangoku.
I-VESA ithi i-DP 1.4 iya kuba yeyona ndlela ifanelekileyo yokufikelela kwiimfuno zokusasazwa kwesandi nevidiyo ezikumgangatho ophezulu kwizixhobo ze-elektroniki eziphezulu.

Injongo yokuzalwa kweDisplayport yayicacile – ukuphelisa i-HDMI. Ke ngoko, xa ithelekiswa ne-HDMI, ayinayo isiqinisekiso se-interface okanye iifizi ze-copyright, kwaye iqokelele inani elikhulu leenkampani ezinkulu kushishino lokubonisa ukuze zenze umbutho we-VISA ukuze zikhuphisane nombutho we-HDMI. Olu luhlu luquka abavelisi abaninzi beetships eziphezulu kunye nabavelisi bezixhobo ze-elektroniki, njenge-Intel, i-NVIDIA, i-AMD, i-Apple, i-Lenovo, i-HP, njalo njalo. Ngoko ke, kunokubonwa ukuba isantya seDisplayport sinamandla kangakanani. Isiphumo sokugqibela somdlalo saziwa ngumntu wonke! Kwi-Displayport interface, ngenxa yentshukumo yokulungiselela ye-HDMI interface, isiphumo sokwazisa se-Displayport interface kwiindawo ezininzi asizange sibe sihle. Nangona kunjalo, umoya wenkqubela phambili oqhubekayo we-Displayport interface ukwakhumbuza i-HDMI ukuba iqhubeke ikhula. Umdlalo phakathi kwezi zimbini uya kuqhubeka kwixesha elizayo.

Ngomhla wama-28 kweyeNkanga, igosa le-HDMI Forum libhengeze ukuqaliswa ngokusesikweni komgangatho wamva nje wobugcisa we-HDMI 2.1.

Xa kuthelekiswa nangaphambili, utshintsho olubalulekileyo kukwanda okukhulu kwe-bandwidth, ngoku enokuxhasa iividiyo ze-10K kwinqanaba eliphezulu. I-bandwidth yangoku ye-HDMI 2.0b yi-18 Gbps, ngelixa i-HDMI 2.1 iza kunyuka iye kwi-48 Gbps, enokuxhasa ngokupheleleyo iividiyo ezingenalahleko ezinezisombululo kunye namazinga okuhlaziya afana ne-4K/120Hz, 8K/60Hz, kunye ne-10K, kwaye ixhasa i-dynamic HDR. Ngenxa yesi sizathu, umgangatho omtsha wamkele intambo entsha yedatha yesantya esiphezulu (i-Ultra High Speed ​​​​HDMI Cable).
