Izixhobo ze-HDMI: injongo, inkcazo ye-interface

I-HDMI ngumgangatho wokudibanisa iindidi ze-multimedia eziphezulu. Esi sikhombiselwano sifakwe kuma-adapters evidiyo kwiikhompyutha zobuqu, abagadi kunye neTV. I-HDMI-standard inikezela ukudluliselwa kwanoma yimaphi umboniso wevidiyo ongezantsi, kunye nedatha ye-3D-TV. Ukongeza, i-interface iyakwazi ukuthumela izithuba ezisibhozo zolwazi lwamajoni edijithali. I-teknoloji ye-HDMI inomgaqo-nkqubo wokukhusela idatha ekukhupheni okungagunyazisiweyo. Esi sikhokelo sikwazi ukuxhasa uxhumano lwe-Ethernet, isantya esingu-100 Mbps.

I-HDMI iziseko kunye neentlobo zazo

Kukho iintlobo ezi-5 zababambisi:

Uhlobo oluqhelekileyo namhlanje luhlobo lwe-A, olwamkelwa ngo-2002 kwi-1.0. Ezi fowuni ze-HDMI zinama-19 oonxibelelwano, ziyakwazi ukuxhasa i-digital interface DVI-D ngokusebenzisa i-adapter. Le teknoloji inokudlulisela iimpawu zevidiyo njenge-HDTV (i-1920 × 1080 isombululo).

2. Uhlobo lwe-B lwamkelwe kanye kunye neyokuqala, kodwa okwangoku alusebenzi. Ezi ntengiso ze-HDMI ziqulethe oonxibelelwano abangama-29 kwaye banakho ukuxhasa uxhulumaniso lwe-DVI-D. Banegunya elinokuba kabini uhlobo lwe-A. Ukongeza, banokuxhuma amadivayisi apho ukwandiswa ngu-3840x2400 (WQUXGA).

3. Uhlobo lwe-C lwamkelwe ngo-2006 (lunegama lesibini - i-mini-HDMI) kwinqanaba 1.3. Ezi zixhumo zenzelwe izixhobo eziphathekayo. Abaxhasi be-C abanxibelelwano abangama-19, banokuxhumeka kuhlobo lwe-A ngokusebenzisa i-adapter.

Uhlobo lwe-D luyamkelwa ngo-2009 (igama lesibili li-micro-HDMI) kwi-1.4. Ezi mphulo zeHDMI nazo zinezikhonkwane ezingu-19. Olu hlobo lunxibelelwano lisetyenziswe kwiifowuni zeefowuni, iikhamera zevidiyo, iipilisi kunye nezinye izixhobo ezifanayo. Ubukhulu be-micro-HDMI bincinci kuncinci kune-micro-USB kunye nesiqingatha kangangoko njenge-HDMI encinane.

5. Uhlobo lwe-E-type, olwamkelwe ngowama-2009, lujoliswe ekunxibelelaneni kwangaphakathi kweemoto zomsindo kunye nevidiyo. Esi sibonakaliso sibonakaliswe ukunganyaniseki okwandayo kwiinguqu zokushisa kunye nokutshintsha.

Ukususela ngo-2006, iintambo ze-HDMI ziye zahlulwa zibe ziindidi zibini: i-speed-speed kunye nomgangatho. Olu xhasayo luxhasa uxhaso lwe-75 MHz kwaye lubonelela nge - 2.25 Gbit / s. Kwaye isantya esiphezulu sisebenza kwi-340 MHz (10.2 Gbit / s) kunye nenkxaso yanda ngokuphindaphindiweyo kunye nobunzulu bombala.

I-HDMI Outlet: Xhuma

Khawuqwalasele ukuxubusha kwezona zinto zidume kakhulu kwixesha le-HDMI-outlet (olu luhlobo lwe-A nohlobo lwe-C). Njengoko sele sele khankanywe ngasentla, zombini ezo zinto zidibeneyo zidibene no-19, kuphela indawo yazo eyahlukileyo. Kwi-A-hlobo, izigqibo zilungiselelwe ngemigangatho emibini, kunye nohlobo lwe-C, kwelinye. Injongo yoonxibelelwano iboniswa kwisithombe. Ukubalwa kwezikhonkwane kuhlobo lwe-C kuya kulandelelwano, kwaye ngohlobo lwe-A umgca ophezulu ungangqali, umgca ongaphantsi unjalo.

Isiphelo

Kukho ama-adapters amaninzi kwi-interface ye-HDMI. Kukho iindlela ezahlukeneyo zokudibanisa phakathi kweentlobo ze-HDMI (umzekelo, i-adapter-outlet-outlet-i-HDMI-outlet iboniswa kwisithombe esingentla). Kwakhona, kukho ama-adapters okudibanisa nezinye i-interfaces, umzekelo, nge-DVI-D, nabanye abaninzi. Nangona kunjalo, xa usebenzisa, khumbula ukuba lo mgangatho, nangona awuchazi ubude obude bekhebula, kodwa, njengoko kubonisa ukubonakalisa, akufanele kudlule kwiimitha ezili-15. Ukudluliselwa kwembonakalo kumgama omde, kucetyiswa ukuba kusetyenziswe abaphinda baphinda, ama- signal amplifiers, kunye neentambo ezisebenzayo kunye ne- fiber-optic.
