Nhanganyaya yeDisplayPort, HDMI uye Type-C Interfaces
Musi waNovember 29, 2017, HDMI Forum, Inc. yakazivisa kuburitswa kweHDMI 2.1, 48Gbps HDMI, uye 8K HDMI zvakatemwa, zvichiita kuti zviwanikwe kune vese HDMI 2.0 adopters. Iyo chiyero chitsva inotsigira 10K resolution @ 120Hz (10K HDMI, 144Hz HDMI), ine bandwidth yakawedzera kusvika 48Gbps, uye inouisa ine simba HDR uye inosiyana yekuzorodza mwero (VRR) matekinoroji.
Musi waChikunguru 26, 2017, mubatanidzwa we USB 3.0 Promoter Group, unosanganisira makambani ehunyanzvi akadai seApple, HP, Intel, neMicrosoft, akazivisa USB 3.2 standard (USB 3.1 C TO C, USB C 10Gbps, Type C Rurume KUMurume), inotsigira maviri-channel 20Gbps kutapurirana uye kurudziro isina kufambiswa Type-C.
Musi waKurume 3, 2016, VESA (Vhidhiyo Electronics Standards Association) yakaburitsa zviri pamutemo vhezheni itsva yeaodhiyo-yekuona yekufambisa standard, DisplayPort 1.4. Iyi vhezheni inotsigira 8K@60Hz uye 4K@120Hz, uye kekutanga inobatanidza tekinoroji yekumanikidza tekinoroji (DSC 1.2).

Zvinotarisirwa kuburitswa zviri pamutemo kwezviyero zvakagadziridzwa
DisplayPort 1.4 yakajairwa yakaburitswa zviri pamutemo! Inotsigira 60Hz 8K vhidhiyo
Musi waKurume 1st, VESA (Vhidhiyo Electronics Standards Association) yakazivisa zviri pamutemo vhezheni itsva yeaodhiyo-yekuona yekufambisa standard DisplayPort 1.4. Iyo chiyero chitsva inowedzera kugona kufambisa vhidhiyo uye data kuburikidza neType-C (USB C 10Gbps, 5A 100W USB C Cable), uku ichitsigira HDR metadata kutapurirana uye yakawedzera kutaurwa. Iyo chiyero chitsva inoonekwa seyekutanga huru yekuvandudza mushure mekuburitswa kweDisplayPort 1.3 munaGunyana 2014.
Panguva imwecheteyo, iyi zvakare yekutanga DP chiyero inotsigira DSC 1.2 (Display Stream Compression) tekinoroji. Muiyo DSC 1.2 vhezheni, 3: 1 isingarasikike vhidhiyo yekumanikidza compression inogona kubvumidzwa.
Iyo "Alternate Mode (Alt Mode)" yakapihwa neDP 1.3 standard inototsigira kufambisa panguva imwe chete yevhidhiyo uye data hova kuburikidza ne USB Type-C uye Thunderbolt nzvimbo. Nepo DP 1.4 ichiitora danho rinoenderera mberi, ichibvumira kufambisa panguva imwe chete kweyepamusoro-tsanangudzo vhidhiyo nepo SuperUSB (USB 3.0) ichishandiswa kufambisa data.
Pamusoro pezvo, DP 1.4 ichatsigira 60Hz 8K resolution (7680 x 4320) HDR vhidhiyo pamwe ne120Hz 4K HDR vhidhiyo.
Zvimwe zvigadziriso zveDP 1.4 ndezvizvi:
1. Forward Error Correction (FEC): Chimwe chikamu cheDSC 1.2 tekinoroji, inogadzirisa yakakodzera kukanganisa kushivirira paunenge uchimanikidza vhidhiyo yekubuda kune ekunze kuratidzwa.
2. HDR Metadata Transmission: Nokushandisa "secondary data packet" muchirongwa cheDP, inopa rubatsiro rwezvino CTA 861.3 chiyero, iyo inobatsira zvikuru DP-HDMI 2.0a yekushandura protocol. Pamusoro pezvo, inopa yakanyanya kuchinjika metadata packet kutapurirana, inotsigira remangwana rine simba HDR.
3. Yakawedzerwa Kufambiswa Kwemaodhiyo: Iyi dhairekitori inogona kuvhara zvinhu zvakaita se32-bit audio channels, 1536kHz sampling rate, uye ese anozivikanwa maodhiyo mafomati parizvino.
VESA inotaura kuti DP 1.4 ichava yakanyanya kunaka interface chiyero kusangana nemhando yepamusoro yekuteerera uye vhidhiyo yekufambisa zvinodiwa zvemagetsi ekupedzisira emagetsi.
Chinangwa chekuzvarwa kweDisplayport chaive chakajeka - kubvisa HDMI. Nokudaro, kana ichienzaniswa neHDMI, haina interface certification kana copyright fees, uye yakaunganidza nhamba huru yemakambani makuru muindasitiri yekuratidzira kuti aumbe VISA association kukwikwidzana neHDMI association. Rondedzero iyi inosanganisira akawanda epamusoro-yekupedzisira chip vanogadzira uye emagetsi ekugadzira zvigadzirwa, seIntel, NVIDIA, AMD, Apple, Lenovo, HP, zvichingodaro. Nekudaro, zvinogona kuoneka kuti kutyisa kweDisplayport kunotyisa sei. Mhedzisiro yekupedzisira yemutambo inozivikanwa kune vese! YeDisplayport interface, nekuda kwekutanga kufamba kweHDMI interface, iyo yekuzivikanwa mhedzisiro yeDisplayport interface muminda yakawanda yanga isina kunaka. Nekudaro, mweya unoenderera mberi weDisplayport interface unoyeuchidzawo HDMI kuti irambe ichikura. Mutambo pakati pevaviri uchaenderera mberi mune ramangwana.
Musi wa28 Mbudzi, mukuru weHDMI Forum akazivisa kuvhurwa zviri pamutemo kweyazvino HDMI 2.1 technical standard.
Kuenzaniswa nekare, shanduko yakakosha ndeyekuwedzera kunoshamisa kwebandwidth, iyo ikozvino inogona kutsigira 10K mavhidhiyo padanho repamusoro. Ikozvino bandwidth yeHDMI 2.0b ndeye 18 Gbps, nepo HDMI 2.1 ichikwira kusvika ku48 Gbps, iyo inogona kutsigira zvizere mavhidhiyo asina kurasikirwa ane zvigadziriso uye mitengo yekuzorodza yakadai se4K/120Hz, 8K/60Hz, uye 10K, uyewo inotsigira dynamic HDR. Nechikonzero ichi, chiyero chitsva chatora tambo nyowani-yepamusoro-yekukurumidza data (Ultra High Speed HDMI Cable).
