Okwu mmalite na DisplayPort, HDMI na Ụdị-C Interfaces
Na Nọvemba 29, 2017, HDMI Forum, Inc. kwupụtara mwepụta nke HDMI 2.1, 48Gbps HDMI, na nkọwa 8K HDMI, na-eme ka ha dị maka ndị na-akwado HDMI 2.0 niile. Ọkọlọtọ ọhụrụ ahụ na-akwado mkpebi 10K @ 120Hz (10K HDMI, 144Hz HDMI), yana bandwidth mụbara ruo 48Gbps, wee webata HDR ike na teknụzụ ume ọhụrụ (VRR).
Na July 26, 2017, njikọ njikọ USB 3.0 Promoter Group, nke gụnyere ụlọ ọrụ teknụzụ dị ka Apple, HP, Intel na Microsoft, kwupụtara ọkọlọtọ USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Ụdị C Nwoke TO Nwoke), nke na-akwado dual-channel 20Gbps.
Na Maachị 3, 2016, VESA (Video Electronics Standards Association) weputara ọkwa ọhụrụ nke ọkọlọtọ mgbasa ozi ọdịyo-visual, DisplayPort 1.4. Ụdị a na-akwado 8K@60Hz na 4K@120Hz, na nke mbụ na-ejikọta teknụzụ mkpakọ iyi egwu (DSC 1.2).

Atụrụ anya mwepụta ọkwa ọkwa emelitere
A tọhapụrụ ọkọlọtọ DisplayPort 1.4! Na-akwado vidiyo 60Hz 8K
Na Maachị 1st, VESA (Video Electronics Standards Association) kwuputara ọkwa ọhụrụ nke ọkọlọtọ mgbasa ozi ọdịyo-visual DisplayPort 1.4. Ọkọlọtọ ọhụrụ ahụ na-ebuli ikike ibufe vidiyo na data site na ụdị-C (USB C 10Gbps, 5A 100W USB Cable), ebe na-akwado nnyefe metadata HDR yana nkọwapụta ọdịyo agbatị. A na-ahụta ọkọlọtọ ọhụrụ ahụ dị ka mmelite izizi izizi ka ahapụchara DisplayPort 1.3 na Septemba 2014.
N'otu oge ahụ, nke a bụkwa ọkọlọtọ DP nke mbụ na-akwado teknụzụ DSC 1.2 (Display Stream Compression). Na ụdị DSC 1.2, enwere ike ikwe ka mkpakọ iyi vidiyo na-enweghị atụ 3:1.
"Ụdị Nhọrọ ọzọ (Alt Mode)" nyere site na ọkọlọtọ DP 1.3 na-akwado nkwado n'otu oge nke vidiyo na iyi data site na USB Type-C na Thunderbolt interfaces. Ọ bụ ezie na DP 1.4 na-ewega ya n'ihu, na-enye ohere maka ịnyefe vidiyo dị elu n'otu oge mgbe SuperUSB (USB 3.0) na-eji maka nnyefe data.
Na mgbakwunye, DP 1.4 ga-akwado 60Hz 8K mkpebi (7680 x 4320) HDR vidiyo yana vidiyo 120Hz 4K HDR.
Mmelite ndị ọzọ nke DP 1.4 bụ ndị a:
1. Mmezi njehie na-aga n'ihu (FEC): Akụkụ nke teknụzụ DSC 1.2, ọ na-ekwu maka nnabata mmejọ kwesịrị ekwesị mgbe ị na-akpakọ vidiyo maka mmepụta na ngosipụta mpụga.
2. HDR Metadata Nyefee: Site na iji "ngwugwu 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 ntụgharị DP-HDMI 2.0a. Na mgbakwunye, ọ na-enye nnyefe ngwugwu metadata ọzọ na-agbanwe agbanwe, na-akwado HDR ike ike n'ọdịnihu.
3. Mgbasawanye Audio Transmission: Nke a nkọwapụta nwere ike kpuchie akụkụ ndị dị ka 32-bit audio ọwa, 1536kHz sampling ọnụego, na niile mara audio formats ugbu a.
VESA na-ekwu na DP 1.4 ga-abụ ọkọlọtọ interface kachasị mma iji zute ihe dị elu chọrọ ọdịyo na nnyefe vidiyo nke ngwaọrụ eletrọnịkị dị elu.
Ebumnuche nke ọmụmụ nke Displayport doro anya - iji kpochapụ HDMI. Ya mere, atụnyere HDMI, ọ nweghị interface interface ma ọ bụ ụgwọ nwebisiinka, na-achịkọtala ọnụ ọgụgụ buru ibu nke isi ụlọ ọrụ na ngosi ụlọ ọrụ na-etolite VISA mkpakọrịta na-asọmpi megide HDMI mkpakọrịta. Ndepụta a gụnyere ọtụtụ ndị na-emepụta mgbawa dị elu na ndị na-emepụta ngwá electronic, dị ka Intel, NVIDIA, AMD, Apple, Lenovo, HP, na ndị ọzọ. Ya mere, enwere ike ịhụ ka ọkụ nke Displayport siri dị. Ihe ikpeazụ nke egwuregwu a maara nke ọma! Maka ihe ngosi Displayport, n'ihi mbugharị mbugharị nke interface HDMI, mmetụta mgbasa ozi nke Displayport interface n'ọtụtụ mpaghara adịghị mma. Agbanyeghị, mmụọ ọganihu na-aga n'ihu nke interface Displayport na-echetakwa HDMI ka ọ nọgide na-etolite. Egwuregwu dị n'etiti abụọ ahụ ga-aga n'ihu n'ọdịnihu.
Na Nọvemba 28th, onye ọrụ gọọmentị HDMI Forum kwupụtara mwepụta gọọmentị nke ọkọlọtọ teknụzụ HDMI 2.1 kachasị ọhụrụ.
Tụnyere na mbụ, mgbanwe kachasị dị ịrịba ama bụ mmụba dị egwu na bandwit, nke nwere ike ịkwado vidiyo 10K ugbu a na ọkwa kachasị elu. bandwidth ugbu a nke HDMI 2.0b bụ 18 Gbps, ebe HDMI 2.1 ga-abawanye ruo 48 Gbps, nke nwere ike kwado vidiyo na-enweghị atụ na mkpebi yana ọnụego ume ọhụrụ dị ka 4K/120Hz, 8K/60Hz, na 10K, ma na-akwado HDR ike. N'ihi nke a, ọkọlọtọ ọhụrụ a nakweere eriri data ultra-speed ọhụrụ (Ultra High Speed HDMI Cable).
