Intshayelelo kwi-DisplayPort, i-HDMI kunye ne-Type-C Interfaces
Ngomhla we-29 kaNovemba, i-2017, i-HDMI Forum, i-Inc. yazisa ukukhululwa kwe-HDMI 2.1, i-48Gbps HDMI, kunye neenkcukacha ze-8K HDMI, ezenza zifumaneke kubo bonke abamkeli be-HDMI 2.0. Umgangatho omtsha uxhasa isisombululo se-10K @ 120Hz (10K HDMI, 144Hz HDMI), kunye ne-bandwidth yanda ukuya kwi-48Gbps, kwaye yazisa i-HDR eguquguqukayo kunye nezinga lokuhlaziya (VRR) iteknoloji.
NgoJulayi 26, i-2017, i-USB 3.0 Promoter Group alliance, equka iinkampani zobuchwepheshe ezifana ne-Apple, i-HP, i-Intel, kunye ne-Microsoft, ibhengeze umgangatho we-USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), exhasa i-double-channel 20Gbps-transmission njenge-interface ye-unified-C.
Ngomhla we-3 ka-Matshi, i-2016, i-VESA (i-Video Electronics Standards Association) ikhuphe ngokusemthethweni inguqu entsha yomgangatho wokuhanjiswa kwe-audio-visual, i-DisplayPort 1.4. Le nguqulo ixhasa i-8K @ 60Hz kunye ne-4K @ 120Hz, kwaye okokuqala idibanisa iteknoloji yokunyanzeliswa komjelo wokubonisa (DSC 1.2).

Ukukhutshwa ngokusemthethweni kwemigangatho ehlaziyiweyo
I-DisplayPort 1.4 esemgangathweni ikhutshwe ngokusemthethweni! Ixhasa ividiyo ye-60Hz 8K
Ngomhla woku-1 kuMatshi, i-VESA (i-Video Electronics Standards Association) yazisa ngokusemthethweni inguqulelo entsha yomgangatho wokuhanjiswa kwe-audio-visual DisplayPort 1.4. Umgangatho omtsha ukhulisa ngakumbi ukukwazi ukuhambisa ividiyo kunye nedatha nge-Type-C (USB C 10Gbps, 5A 100W USB C Cable), ngelixa uxhasa ukuhanjiswa kwemethadatha ye-HDR kunye neenkcukacha zomsindo ezongeziweyo. Umgangatho omtsha uthathwa njengohlaziyo lokuqala oluphambili emva kokukhululwa kweDisplayPort 1.3 ngoSeptemba 2014.
Ngelo xesha, oku kwakhona umgangatho wokuqala we-DP oxhasa i-DSC 1.2 (i-Display Stream Compression) iteknoloji. Kwinguqulo ye-DSC 1.2, i-3: i-1 yokunyanzeliswa komjelo wevidiyo engalahlekiyo ingavunyelwa.
"Indlela engenye (i-Alt Mode)" enikezelwa ngumgangatho we-DP 1.3 sele ixhasa ukuhanjiswa kwangaxeshanye kwevidiyo kunye nemijelo yedatha nge-USB Type-C kunye ne-Thunderbolt interfaces. Ngelixa i-DP 1.4 ithatha inyathelo eliya phambili, ivumela ukuhanjiswa kwangaxeshanye kwevidiyo ephezulu yenkcazo ngelixa i-SuperUSB (i-USB 3.0) isetyenziselwa ukuhanjiswa kwedatha.
Ukongeza, i-DP 1.4 iya kuxhasa isisombululo se-60Hz 8K (7680 x 4320) ividiyo ye-HDR kunye nevidiyo ye-120Hz 4K HDR.
Olunye uhlaziyo lweDP 1.4 lulandelayo:
1. Ukulungiswa kwempazamo yokuPhambili (i-FEC): Inxalenye ye-DSC 1.2 iteknoloji, ijongana nokunyamezela impazamo efanelekileyo xa ucinezela ividiyo yokuphuma kwimiboniso yangaphandle.
2. Ukuhanjiswa kweMetadata ye-HDR: Ngokusebenzisa "ipakethi yedatha yesibini" kumgangatho we-DP, inika inkxaso kumgangatho weCTA 861.3 wangoku, oluncedo kakhulu kwi-DP-HDMI 2.0a yokuguqulwa kweprotocol. Ukongeza, ibonelela ngokuhanjiswa kwepakethe yemetadata eguquguqukayo ngakumbi, exhasa iHDR eguqukayo yexesha elizayo.
3. UHanjiso olwandisiweyo lweAudio: Le nkcazo inokugubungela imiba efana ne-32-bit yeziteshi zeaudio, ireyithi yesampulu ye-1536kHz, kunye nazo zonke iifomati zeaudio ezaziwayo ngoku.
I-VESA ithi i-DP 1.4 iya kuba ngowona mgangatho ufanelekileyo wojongano ukuhlangabezana nemigangatho ephezulu yeemfuno zeaudio kunye nevidiyo yokuhanjiswa kwezixhobo zombane eziphezulu.
Injongo yokuzalwa kweDisplayport yayicacile - ukuphelisa i-HDMI. Ngoko ke, xa kuthelekiswa ne-HDMI, ayinaso isatifikethi se-interface okanye imirhumo ye-copyright, kwaye iqokelele inani elikhulu leenkampani ezinkulu kwimboni yokubonisa ukwenza umbutho we-VISA ukukhuphisana nombutho we-HDMI. Uluhlu lubandakanya abaninzi abavelisi be-chip eziphezulu kunye nabavelisi bezixhobo zombane, ezifana ne-Intel, i-NVIDIA, i-AMD, i-Apple, i-Lenovo, i-HP, njalo njalo. Ke, kunokubonwa ukuba ubukhali kangakanani na umfutho weDisplayport. Isiphumo sokugqibela somdlalo saziwa ngabantu bonke! Kwi-interface yeDisplayport, ngenxa yokuhamba kwangaphambili kwe-HDMI ujongano, isiphumo sokuthandwa kwe-Displayport interface kwiinkalo ezininzi azizange zilunge. Nangona kunjalo, umoya oqhubekayo wenkqubela phambili ye-Displayport interface iphinda ikhumbuze i-HDMI ukuqhubeka nokuphuhlisa. Umdlalo phakathi kwezi zibini uya kuqhubeka kwixesha elizayo.
Ngomhla we-28 kaNovemba, igosa le-HDMI Forum libhengeze ukuqaliswa ngokusemthethweni kwe-HDMI 2.1 yomgangatho wobugcisa.
Xa kuthelekiswa nangaphambili, olona tshintsho lubalulekileyo kukunyuka okumangalisayo kwi-bandwidth, enokuthi ngoku ixhase iividiyo ze-10K kwinqanaba eliphezulu. I-bandwidth yangoku ye-HDMI 2.0b yi-18 Gbps, ngelixa i-HDMI 2.1 iya kunyuka ukuya kwi-48 Gbps, enokuxhasa ngokupheleleyo iividiyo ezilahlekileyo kunye nezigqibo kunye namazinga okuhlaziya afana ne-4K / 120Hz, 8K / 60Hz, kunye ne-10K, kunye nenkxaso ye-HDR enamandla. Ngenxa yesi sizathu, umgangatho omtsha uye wamkela intambo entsha yedatha ye-ultra-high-speed (i-Ultra High Speed HDMI Cable).
