The ka khayr badan DVI HDMI? Egyihiin iyo khilaafaadka

Kormeer la xidhiidha qalabka kale adigoo isticmaalaya interfaces kala duwan, kuwaas oo hadda waa idiin badiyo. Iyadoo ku xiran xalka farsamada fursadaha isku xirnaanta ku yimaadaan laba nooc - analog iyo digital. Arintaan waxaa matala laba interfaces weyn - DVI D ama HDMI. Waa kuwee waa ka fiican, iyo waxa, dhab ahaantii, waa faraqa u dhexeeya teknoolajiyada kuwanu? In raalli ee isku xira ee loo baahan yahay in la sameeyo doorasho? Next laga wada hadli doonaa si faahfaahsan, HDMI fiican ka badan DVI.

Shuruudaha technology casri ah

Si loo go'aamiyo oo isku xira waa ugu fiican - DVI ama HDMI ah, waxay ka caawisaa in la fahmo sababta ay lagama maarmaan tahay oo kaliya in ay ka fiirsan labadan naadi, sababtoo ah waxaa jira interfaces kale, tusaale ahaan, DisplayPort ama VGA. Waa midda koowaade, DisplayPort waxaa inta badan loo isticmaalaa in lagu xiro monitor in ay PC ka, bixinta xiriir ka dhexeeya badan screens, laakiin interface this xaqiiqdii waa ma ku haboon yahay format HD. VGA iyo qaban waqti xaadirkaan waxaa durbaba loo arkaa xalka huriye, isticmaalka waxa ka mid ah in ay technology siiyey shirkado badan keentay. By habka, si ay u VGA mahad isugu gudbiyo signal analog.

Laakiin baahinta analog Sidoo kale waa hadda markuu tagayu galay asalka ay sabab u tahay xaqiiqda ah in inta badan si cad u muujinaysaa ayaa haddana ceebaha image ah. Qalabka wuxuu u horeysay badasha signalka digital in analog, ka dibna qeybsanaan. sawirada aan loo baahnayn beddelaad keenaysaa in waxa u muuqda on faragelinta shaashadda - dhibaato joogto ah u yihiin naf baxay, nuqulo ka mid ah walxaha, badhamada ama text. Gaalda Rajadu waa in waxyaalaha cad cad kuna sugan kormeerayaal LCD casriga ugu horeysay oo ay taageeraan oo kaliya la xidhiidha VGA ah.

Sida naadi ee, hadda saarayaasha ugu waxaa lagu dhejiyay on the technology dekedaha guddi danbe labada cable ee digital. Laakiin sida caadiga ah, waxaa kaliya adkaynaysaa dhibaato marka aad u baahan tahay in ay go'aan ka gaarto waxa ugu fiican cable - HDMI ama DVI.

Tilmaamo Common ee interface ah

Oo HDMI, iyo signal DVI video loo kala qaado iyadoo la isticmaalayo technology isla, oo la yidhaahdo TMDS ah. Warbixin daruuri ah in ay dhacdo tani waxaa la encoded si aad u hesho isku xigxiga ugu wada gelinno. Thanks to dambaysta ah, inta jeer ee aad u dheer iyo, sida natiijo ah, tayada image fiican.

Intaa waxaa dheer, waayo, mid, iyo cable ka mid ah oo keliya loo isticmaalo dekedda kale (inkastoo xaqiiqda ah in HDMI waa channel hal, laakiin DVI ah - xal multi-channel in la hoos looga hadli doonaa). Tani waa suurto gal ah iyadoo la adeegsanayo adapters gaar ah.

Otherness

Qaar badan oo dadka isticmaala PC ayaa ku dooranaya ay guushu ku -Qeexid Sare ee Isgaarsiinta Wajahadda. Maxaad sidaas tahay - fiican HDMI ah? DVI ma ku faani kartaa? Waxaa jira laba kala duwan oo waaweyn:

1. HDMI cable gudbin karaa oo keliya ma aha, laakiin sidoo kale video dhawaaqa. Waxay bixisaa tayo sare leh aan ka dhawaajiyaan oo keliya, laakiin sidoo kale images. Inta lagu daydo DVI shaqo this ma laha, in kastoo, dabcan, waxaa ka reeban in ay xukunka.
2. High-Qeexid Muuqaal Wajahadda xadhig waa hal channel ah, laakiin xawaaraha kala iibsiga xogta gaaro boqol megabits per labaad. Laakiin waxyaabaha shirkad tartan ka jira kanaallo badan, mid ka mid ah oo gudbiya signal ah analog. Waayo, qalabka ordaya on signal noocan oo kale ah, DVI xudunta - kaliya uubs. Sidaas darteed, shirkadda xajiya ula socdo jeer ah, laakiin ma iska indha baahida milkiilayaasha qalab ku faani karo cusub "walxahaas."

Si aad u go'aansato, si fiican HDMI ka badan DVI, waxaad u baahan tahay in la fahmo in tayada image ee inta badan ku xiran tahay qalabka aad rabto in aad ku xidhi. On image in muuqataa shaashadda xoog signal saameeyeen. Laakiin tayada xasiloonida iyo image of cable gudbinta waxaa hore loo siiyay.

Laakiin ha isku dayin in ay ku xidhmaan mid cable oo meel kale, waayo, taasu waxaa jira adapters gaar ah. Haddii kale, waxaad uun waayi kartaa dhawaaq. Labada interfaces kastoo la technology hal shaqeeyo, laakiin farqiga u isu dareemay.

High-Qeexid Muuqaal Wajahadda

Maxaa ka fiican tahay HDMI DVI, sidaas darteed tani waa dhab ahaan waxa High-Qeexid Muuqaal Wajahadda waxaa loo isticmaalaa by shirkado badan oo soo saara qalabka. Isagu waa interface si caadi ah, via hdmi la xidhi karaa ma aha oo kaliya in telefishinada iyo kormeerayaasha ee kombiyuutarada, laakiin sidoo kale laptops, kiniin iyo telefoonada smart, consoles'ka ciyaarta iyo ciyaartoyda.

cable A oo ka kooban hal channel oo keliya, weli waa widescreen kala duwan, jidaynayey ka qalabka warbaahinta kala duwan si ay u sameeyaan nidaam dhan. Recently, xaaladaha qaarkood, gaar ahaan loo baahan yahay.

versions of New cable u leedahay waafaqsan fiican iyo fududahay in la badalo model hore. HDMI ayaa bandwidth wanaagsan, taas oo muhiim u ah isagana ama kuwa isticmaala jecel xawaare sare iyo dhawaaqa hagaagtay. Isla mar ahaantaana, HDMI si buuxda cusub, kaliya taageeraa format digital. Taasi waa, wax kasta oo qalab model ka weyn iyadoo la isticmaalayo waxa aanu ku xirmaan.

Wajahadda Visual Digital

DVI-interface waxay leedahay saddex qeybood oo taageeraya qaabab kala duwan - digital, analog iyo analog-to-digital. Image isagoo ballaarinta sare, cable this gudbin karaan in ka badan ka fog oo ah wax ka badan shan mitir. gudbinta Signal in la sameeyo waxaa laga yaabaa in laba hababka. First - link hal (mode hal), labaad - link dual (dual mode). Arintaan waxay bixisaa shaqo ee mawjadaha sare. Tusaale ahaan, marka sawirka ay tayadiisu hoosayso marka la isticmaalayo hab keli ah waa dual link daawaynta xaaladda.

faa'iidada tartanka

HDMI kiis kasta, waa interfaces ka maskax. ku dhiirigelinayaan in uu raaco isbeddel oo tag la wakhtiyada. daydo Most of technology casriga ah ee la joogo iyo mustaqbalka dhow si xaqiiqo ah u isticmaali doonaa noocan ah cable.

HDMI ama DVI in computer ah, waxaa wanaagsan in la doorto waa? Xaaladdan oo kale, waxaad isticmaali kartaa mid ama interface kale. doorashada ugu dambaysaa waxay ku xiran tahay Ahaado. Haddii tayada codka muhiim ah, waxaa wanaagsan in la isticmaalo isku xira ugu horeysay, ay ka maqan yihiin lagama maarmaan this, DVI sidoo kale ku haboon yahay la xidhiidha a. Noocan ah interface waa gaar ahaan fiican, sababtoo ah horumarinta ay, in kastoo guuxayay technology, laakiin ha iloobin kuwa isticmaala qalabka ka weyn. Ka dib oo dhan, xataa wax badan oo dadka isticmaala leeyihiin kombiyuutarada iyo telefishanka, kaas oo ay leeyihiin "ma isbedel." Xaaladdan oo kale, si fiican si ay u joojiyaan on DVI ah.
