DVI-xira: description ee ujeedada, sifooyinka qalabka

DVI-xira loo isticmaalo in telefishin oo casri ah (plasma, LCD), kaararka garaafyada LCD-monitor iyo kumbiyuutarada. Magaca "DVI" waxaa laga soo gaabiyay Ingiriisi ah ee Digital VisualInterface, kaas oo tarjumayaa "interface muuqaal digital". DVI-xira waxaa la sameeyey iyo ugu horeysay soo bandhigay sanadkii 1999 by Group Working Display Digital. Waxaa ka mid ah kooxda caalamiga ah wax soo saarka ee kombiyuutarada iyo kormeerayaasha, sida Intel, Compaq, Fujitsu, Silicon Image, Hewlett Packard iyo NEC. DVI-xira badalay ee VGA-interface iyo taariikhda dhow si buuxda u bedelay.

Description DVI-technology

Habka of gudbinta xogta loo isticmaalo in interface this, ee ay Silicon Image. Waxaa iska leh nooc ka mid ah qalabka la isugu gudbiyo xogta serial. DVI-cable ayaa lagu dhisay on mabda'a ah ee labada qaloocin. Saddex lammaane oo silig ka dhigeen waxaa lagu kala qaado midabka (casaan, cagaar iyo buluug), iyo kii afraad - calaamadaha saacba. DVI-xira u ogolaanaya in ay gudbiyaan labada analog signalada digital. Waxaa jira saddex nooc hoosaad interface hoostiisa tixgelin:

• DVI-A - waxaa loo isticmaalaa in gudbiyaan kaliya calaamadaha analog ;
• DVI-I - xira universal loo isticmaalo gudbinta analog iyo signalada digital labadaba;
• DVI-D - si ay u bixiyaan signalada digital oo kaliya.

Intaa waxaa dheer, technology ee ku qalabeysan yahay nidaamka macluumaadka digital ah DVI ilaalinta gaarka ah HDCP in la horumariyo by Intel.

Qasaaraha DVI-interface

Faa'iida ugu weyn ee gudbinta macluumaadka via isku xira waa in la xaddido dhererka cable ka, iyo sidoo kale ku xiran tahay nooca dhimaya ah ayaa sheegay in signal la isugu gudbiyo. Tusaale ahaan, u-ekaanta kordhin 1920x1200 pixels la soo noqnoqoshada ah 60 Hz lagu faafin karaa cable, oo dhererkiisu dhan yahay 5 mitir, iyo cable pyatnadtsatimetrovomu gudbiyaan laga yaabaa in signal ah kaas oo noqon doona tayada ugu badnaan kaliya 1280x1024 pixel at inta jeer ee isku mid ah. Sidaa darteed, marka baahida loo qabo in fiilooyinka dheer u leeyihiin in ay isticmaalaan qalab dheeraad ah - Sammeecado signal gaar ah (repeaters), kuwaas oo kaalinta fogfog qaarkood. Iyada oo cillado kuwaas oo xiriir la leh muuqaalka kore ee dhibcood on kormeeraha iyadoo la isticmaalayo cable tayo liita. Si aad u baabi'iyo saamayn this, waxaa lagama maarmaan ah in la beddelo ama xadhig, ama hoos tayada signal la gelin ah.

DVI-HDMI isku xira

isku xira waxaa loo isticmaalaa gudbinta digital ah calaamadaha HDTV. Waxaan loogu talagalay interface this xiriirayo TV in ay ilaha talooyinka ah. isku xira peculiarity ku xusan waa in ay u gudbin karaan video ma aha oo kaliya, laakiin sidoo kale audio digital. Waxa ay u ogolaataa in ay baahin channels audio 8, la yara ee 24 gelinno. Waxaa jira caddaymaha kala duwan ee interface ku yidhi iyo adabtarada, mahad taas oo ay suurogal tahay in wali noocyada kala duwan ee Xidhiidhiyayaasha. Sidoo kale, HDMI-xira waxaa loo isticmaali karaa in lagu xiro ee PC iyo TV-ga. Waa in la xusuusnaado in interface HDMI-DVI wuxuu kaalmeeyaa hab maamuuska gaar ah loogu talagalay in lagu ilaaliyo content ruqsada ka overwriting aan la ogalayn.

gunaanad

Inkastoo-technology DVI ku dhowaad gebi ahaanba bedelay VGA-interfaces, taariikhda, noocan ah waxaa si balaadhan looga isticmaalaa on Kombuutarada ka weyn. Haddii kaarka video aad jirto DVI-xira, laakiin aad rabto in aad ku xidhi monitor ah in ay taageertaa technology this, markaas waxaad isticmaali kartaa adabtarada gaar ah - DVI-VGA-xira.
