Okwu Mmalite maka DisplayPort, HDMI na Type-C Interfaces
Na Nọvemba 29, 2017, HDMI Forum, Inc. kwupụtara mwepụta nke nkọwapụta HDMI 2.1, 48Gbps HDMI, na 8K HDMI, nke mere ka ha dịrị ndị niile na-anabata HDMI 2.0 mfe. Ọkọlọtọ ọhụrụ a na-akwado mkpebi 10K @ 120Hz (10K HDMI, 144Hz HDMI), ebe bandwidth mụbara ruo 48Gbps, ma webata teknụzụ HDR na mgbanwe mgbanwe ọnụego (VRR).
Na Julaị 26, 2017, njikọ aka nke USB 3.0 Promoter Group, nke mejupụtara ụlọ ọrụ teknụzụ dịka Apple, HP, Intel, na Microsoft, kwupụtara ọkọlọtọ USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), nke na-akwado nnyefe 20Gbps nke ọwa abụọ ma na-akwado Type-C dị ka njikọ ejikọtara ọnụ.
Na Machị 3, 2016, VESA (Video Electronics Standards Association) wepụtara ụdị ọhụrụ nke ọkọlọtọ nnyefe ọdịyo na onyonyo, DisplayPort 1.4. Ụdị a na-akwado 8K@60Hz na 4K@120Hz, ma nke mbụ ya jikọtara teknụzụ mkpakọ iyi ngosi (DSC 1.2).

A na-atụ anya mwepụta gọọmentị nke ụkpụrụ emelitere
E wepụtara ọkọlọtọ DisplayPort 1.4 n'ihu ọha! Na-akwado vidiyo 60Hz 8K
Na Machị 1, VESA (Video Electronics Standards Association) kwupụtara ụdị ọhụrụ nke ọkọlọtọ nnyefe ọdịyo na onyonyo DisplayPort 1.4. Ụkpụrụ ọhụrụ a na-eme ka ikike izipu vidiyo na data dịkwuo mma site na Type-C (USB C 10Gbps, 5A 100W USB C Cable), ebe ọ na-akwado nnyefe metadata HDR na nkọwapụta ọdịyo agbatịkwuru. A na-ewere ọkọlọtọ ọhụrụ a dị ka mmelite mbụ dị mkpa mgbe ewepụtachara DisplayPort 1.3 na Septemba 2014.
N'otu oge ahụ, nke a bụkwa ọkọlọtọ DP mbụ nke na-akwado teknụzụ DSC 1.2 (Display Stream Compression). Na ụdị DSC 1.2, enwere ike ikwe ka mkpakọ vidiyo na-enweghị ihe efu nke 3: 1.
"Ụdị Alternate (Ụdị Alt)" nke ọkọlọtọ DP 1.3 nyere na-akwado mbufe vidiyo na iyi data n'otu oge site na njikọ USB Type-C na Thunderbolt. Ọ bụ ezie na DP 1.4 na-eme ya otu nzọụkwụ ọzọ, na-enye ohere maka mbufe vidiyo dị elu n'otu oge ebe a na-eji SuperUSB (USB 3.0) maka nnyefe data.
Tinyere nke ahụ, DP 1.4 ga-akwado vidiyo HDR nke 60Hz 8K (7680 x 4320) yana vidiyo HDR nke 120Hz 4K.
Mmelite ndị ọzọ nke DP 1.4 bụ ndị a:
1. Mmezi Njehie N'ihu (FEC): Dịka akụkụ nke teknụzụ DSC 1.2, ọ na-edozi ndidi njehie kwesịrị ekwesị mgbe a na-apịachi vidiyo maka mmepụta na ngosipụta mpụga.
2. Nzipu Metadata HDR: Site na iji "packet data nke abụọ" na ọkọlọtọ DP, ọ na-enye nkwado maka ọkọlọtọ CTA 861.3 dị ugbu a, nke bara uru nke ukwuu maka usoro mgbanwe DP-HDMI 2.0a. Na mgbakwunye, ọ na-enye nnyefe ngwugwu metadata dị mfe karị, na-akwado HDR na-agbanwe agbanwe n'ọdịnihu.
3. Mgbasa Ozi Ọdịyo Gbasara: Nkọwapụta a nwere ike ikpuchi akụkụ dịka ọwa ọdịyo 32-bit, ọnụego nlele 1536kHz, na usoro ọdịyo niile a maara ugbu a.
VESA na-ekwu na DP 1.4 ga-aghọ ọkọlọtọ interface kachasị mma iji mezuo ihe achọrọ maka nnyefe ọdịyo na vidiyo dị elu nke ngwaọrụ eletrọnịkị dị elu.
Ebumnuche e ji mụọ Displayport doro anya nke ọma - iwepụ HDMI. Ya mere, ma e jiri ya tụnyere HDMI, ọ nweghị asambodo interface ma ọ bụ ụgwọ nwebisiinka, ọ chịkọtakwala ọtụtụ ụlọ ọrụ dị mkpa na ụlọ ọrụ ngosi iji mepụta njikọ VISA iji lụso njikọ HDMI ọgụ. Ndepụta a gụnyere ọtụtụ ndị na-emepụta chip dị elu na ndị na-emepụta ngwa eletrọnịkị, dị ka Intel, NVIDIA, AMD, Apple, Lenovo, HP, na ndị ọzọ. Ya mere, a pụrụ ịhụ otú ike Displayport si dị ike. Ihe ikpeazụ a rụpụtara bụ ihe a maara nye mmadụ niile! Maka interface Displayport, n'ihi mmegharị HDMI tupu oge eruo, mmetụta mgbasa ozi nke interface Displayport n'ọtụtụ ubi adịchaghị mma. Agbanyeghị, mmụọ ọganihu na-aga n'ihu nke interface Displayport na-echetara HDMI ka ọ nọgide na-etolite. Egwuregwu dị n'etiti ha abụọ ga-aga n'ihu n'ọdịnihu.
Na Nọvemba 28, onye ọrụ HDMI Forum kwupụtara mmalite nke ọkọlọtọ teknụzụ HDMI 2.1 kachasị ọhụrụ.
Ma e jiri ya tụnyere nke mbụ, mgbanwe kachasị mkpa bụ mmụba dị egwu na bandwit, nke nwere ike ịkwado vidiyo 10K ugbu a na ọkwa kachasị elu. Bandwit HDMI 2.0b dị ugbu a bụ 18 Gbps, ebe HDMI 2.1 ga-abawanye ruo 48 Gbps, nke nwere ike ịkwado vidiyo na-enweghị ihe efu nke ọma na mkpebi na ọnụego mmelite dị ka 4K/120Hz, 8K/60Hz, na 10K, ma kwadokwa HDR na-agbanwe agbanwe. N'ihi nke a, ọkọlọtọ ọhụrụ ewerela eriri data ọhụrụ dị oke ọsọ (Ultra High Speed HDMI Cable).
