Iki gice gisobanura insinga ya DisplayPort

Insinga za DisplayPort
Ni uburyo bwo kwerekana amashusho bwa digitale bugezweho bushobora guhuzwa na mudasobwa na monitors, ndetse na mudasobwa na sinema zo mu rugo. Ku bijyanye n'imikorere, DisplayPort 2.0 ishyigikira uburyo bwo kohereza amakuru bwa 80Gb/S ntarengwa. Kuva ku ya 26 Kamena 2019, ikigo gisanzwe cya VESA cyatangaje ku mugaragaro uburyo bushya bwo kohereza amakuru bwa DisplayPort 2.0, buhujwe cyane na Thunder 3 na USB-C. Bushobora guhaza ibyifuzo bya 8K n'ibipimo byo hejuru. Ni yo vugurura rya mbere rikomeye kuva aho protocole ya DisplayPort 1.4 ibereye.
Mbere y’ibyo, uburyo bwo gukoresha interineti bwa DP 1.1, 1.2 na 1.3/1.4 bwari 10.8Gbps, 21.6Gbps na 32.4Gbps uko bikurikirana, ariko igipimo cyiza cyari 80% gusa (kode ya 8/10b), byari bigoye kuzuza ibisabwa na resolution yo hejuru ya 6K na 8K, ubujyakuzimu bw'amabara menshi n'igipimo cyo kuvugurura cyane.
DP 2.0 yongera umuvuduko w’ikoranabuhanga kugeza kuri 80Gbps, kandi ikoresha uburyo bushya bwo gusimbuza, 128/132b, byongera imikorere kugeza kuri 97%. Umuvuduko w’ikoranabuhanga ukoreshwa ni 77.4Gbps, bingana n’inshuro eshatu za DP 1.3/1.4, kandi urenze kure umuvuduko w’ikoranabuhanga wa HDMI 2.1 wa 48Gbps.
Kubera iyo mpamvu, DP 2.0 ishobora gushyigikira byoroshye 8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz n'izindi format zo gusohora. Ntabwo ishobora gushyigikira gusa moniteur iyo ari yo yose ya 8K idakandamijwe, ahubwo ishobora no gushyigikira uburebure bw'amabara ya 30-bit (amabara arenga miliyari). Shyira mu bikorwa 8K HDR.


DisplayPort 2.0: Thunderbolt 3, UHBR, na passive data cable
Ku bijyanye n'imirongo y'amakuru, DP 2.0 ishyiraho uburyo butatu butandukanye, buri bandwidth y'umuyoboro ishyirwa kuri 10Gbps, 13.5Gbps na 20Gbps uko bikurikirana. VESA ibyita "UHBR/Ultra High Bit Rate". Dukurikije bandwidth yitwa UHBR 10, UHBR 13.5, UHBR 20.
Umuyoboro w’ibanze wa UHBR 10 ni 40Gbps, naho umuyoboro w’ibanze ni 38.69Gbps. Insinga z’umuringa zitagira umugozi zishobora gukoreshwa. Umushinga wo kwemeza insinga za DP 8K ubanza urimo, ni ukuvuga ko insinga z’amakuru za DP zinyura mu cyemezo cya 8K zujuje ibisabwa nk’uko UHBR 10 ibyifuza.
UHBR 13.5 na UHBR 20 biratandukanye. Imbibi z'ibanze ni 54Gbps na 80Gbps, naho imbibi z'ingenzi ni 52.22Gbps na 77.37Gbps. Insinga zitagira umuvuduko zishobora gukoreshwa gusa mu kohereza ubutumwa bugufi cyane, nko gufunga mudasobwa.
