HDMI ni ikimenyetso gisanzwe gikoreshwa mubintu byinshi byabaguzi.HDMI isobanura High-Definition Multimedia Interface.HDMI ni igipimo cyihariye kigamije kohereza ibimenyetso biva ahantu, nka kamera, imashini ya Blu-ray, cyangwa imashini ikinira, aho igana, nka monitor.Irasimbuza mu buryo butaziguye ibipimo bishaje nka compte na S-Video.HDMI yatangijwe bwa mbere ku isoko ryabaguzi mu 2004. Mu myaka yashize, habaye verisiyo nshya za HDMI, zose zikoresha umuhuza umwe.Kugeza ubu, verisiyo iheruka ni 2.1, ihujwe na 4K na 8K imyanzuro hamwe nubunini bugera kuri 42,6 Gbit / s.
HDMI yabanje kugenerwa nk'umuguzi, mugihe SDI yagenwe nk'inganda.Kubera iyo mpamvu, HDMI kavukire ntabwo ishyigikira uburebure bwa kabili ndende, cyane cyane iyo imyanzuro irenze 1080p.SDI irashobora kugera kuri 100m muburebure bwa 1080p50 / 60 (3 Gbit / s), mugihe HDMI ishobora kurambura kugeza kuri 15m murwego rumwe.Hariho uburyo bwinshi bwo kwagura HDMI kurenza iyo 15m.Muri iki kiganiro, tuzaganira kuburyo busanzwe bwo kwagura ikimenyetso cya HDMI.
Umugozi mwiza
Niba urenze metero 10, ikimenyetso gitangira gutakaza ubuziranenge.Urashobora kubona byoroshye ibi bitewe nikimenyetso kitageze kuri ecran ya ecran cyangwa ibihangano mubimenyetso bituma ibimenyetso bitagaragara.HDMI ikoresha ikoranabuhanga ryitwa TMDS, cyangwa inzibacyuho-yagabanijwe gutandukanya ibimenyetso, kugirango amakuru yuruhererekane agende neza.Ikwirakwiza ryinjizamo algorithm ya coding igezweho igabanya kwivanga kwa electromagnetiki hejuru yumuringa wumuringa kandi igafasha kugarura isaha ikomeye kubakira kugirango igere ku kwihanganira skew ndende yo gutwara insinga ndende hamwe ninsinga ngufi zihenze.
Kugirango ugere ku nsinga z'uburebure bwa 15m, ukeneye insinga nziza.Ntukemere ko umucuruzi agushuka ngo ugure insinga zihenze zumuguzi hanze kuko umwanya munini, zimeze nkizihendutse.Kubera ko HDMI ari ikimenyetso cyuzuye cya digitale, ntaburyo bwo kwerekana ibimenyetso byujuje ubuziranenge kuruta ubundi buryo.Gusa ikintu kibaho nikimenyetso cyo kumanura mugihe wohereje ibimenyetso byumuvuduko mwinshi hejuru ya kabili ndende cyane cyangwa umugozi udashyizwe kumurongo wihariye wa HDMI.
Niba ushaka kugera kuri 15m ukoresheje umugozi usanzwe, nyamuneka reba neza ko umugozi ukoresha wapimwe kuri HDMI 2.1.Bitewe na TMDS, ibimenyetso bizagera neza neza cyangwa ntibigere na gato.Ikimenyetso cya HDMI kitari cyo kizaba gifite static hejuru yacyo, cyitwa sparkles.Imirabyo ni pigiseli idasobanuwe inyuma mubimenyetso bikwiye kandi byerekanwe mweru.Ubu buryo bwo kwerekana ibimenyetso ni gake cyane, kandi birashoboka cyane ko bivamo umukara, nta kimenyetso na kimwe.
Kwagura HDMI
HDMI yahise yemerwa nkibice byambere byo gutwara amashusho n'amajwi muburyo bwose bwibicuruzwa.Kuberako HDMI nayo itwara amajwi, byahise bihinduka igipimo cya projeteri na ecran nini mubyumba byinama.Kandi kubera ko DSLRs na kamera yo murwego rwabaguzi nayo ifite interineti ya HDMI, ibisubizo byamashusho byumwuga byakiriye HDMI.Kubera ko byemewe cyane nkimikorere kandi iboneka kumurongo wose wumuguzi LCD, birahenze cyane gukoresha mugushiraho amashusho.Mugushiraho amashusho, abayikoresha bahuye nikibazo ko uburebure bwa kabili bushobora kuba 15m gusa.Hariho uburyo bwinshi bwo gutsinda iki kibazo:
Hindura HDMI kuri SDI ninyuma
Iyo uhinduye ibimenyetso bya HDMI muri SDI hanyuma ukagaruka aho ujya, wagura neza ibimenyetso bigera kuri 130m.Ubu buryo bwakoresheje uburebure bwa kabili ntarengwa kuruhande rwoherejwe, buhinduka muri SDI, bukoresha umugozi wuzuye wa 100m, hanyuma buhinduka nyuma yo gukoresha umugozi wuzuye wa HDMI.Ubu buryo busaba insinga nziza ya SDI hamwe na enterineti ebyiri zikora kandi ntabwo ari byiza kubera ikiguzi.
+ SDI ni tekinoroji ikomeye
+ Shyigikira kugeza kuri 130m nibindi mugihe ukoresheje utukingirizo dutukura
- SDI murwego rwohejuru kuri videwo ya 4K ntabwo ihenze cyane
- Guhindura ibikorwa birashobora kuba bihenze
Hindura kuri HDBaseT hanyuma
Iyo uhinduye ikimenyetso cya HDMI kuri HDBaseT, kandi inyuma urashobora kugera kuburebure burebure hejuru ya CAT-6 cyangwa igiciro cyiza cyane.Uburebure ntarengwa burahinduka kubikoresho ukoresha, ariko umwanya munini, 50m + birashoboka rwose.HDBaseT irashobora kandi kohereza imbaraga kubikoresho byawe kugirango bidakenera ingufu zaho kuruhande rumwe.Na none, ibi biterwa nibikoresho byakoreshejwe.
+ HDBaseT ni tekinoroji ikomeye cyane ishyigikiwe na 4K ikemurwa
+ HDBaseT ikoresha cabling ihenze cyane muburyo bwa CAT-6 ya ethernet
- Umuyoboro wa Ethernet uhuza (RJ-45) urashobora kuba woroshye
- Uburebure bwa kabili ntarengwa bitewe nibikoresho byakoreshejwe
Koresha insinga zikora HDMI
Umugozi wa HDMI ukora ni insinga zifite ibyuma byubatswe kuva mumuringa usanzwe kugeza kuri fibre optique.Ubu buryo, umugozi nyirizina ni fibre optique ya fibre muri insulasiyo.Ubu bwoko bwa kabili buratunganye niba ukeneye kubushiraho mugihe cyagenwe, nk'inyubako y'ibiro.Umugozi uroroshye kandi ntushobora kugororwa kuri radiyo runaka, kandi ntugomba gukandagira cyangwa gutwarwa nigare.Ubu bwoko bwo kwagura buhenze ariko bwizewe cyane.Rimwe na rimwe, imwe mu nsinga irangira ntishobora gukomera bitewe nigikoresho kidasohora ingufu zisabwa kubahindura.Ibi bisubizo bizamuka kuri metero 100 byoroshye.
+ Imiyoboro ya HDMI ikora kavukire ishyigikira imyanzuro ihanitse kugeza 4K
+ Fragile kandi ndende ya cabling igisubizo kubikorwa byashizweho
- Umugozi wa fibre optique uroroshye kunama no kumenagura
- Ntabwo ibyerekanwa byose cyangwa ibyuma bisohora ibintu bisohora voltage ikwiye
Koresha ibikorwa bya HDMI Byagutse
Kwagura ibikorwa bya HDMI ni inzira nziza yo kwagura ibimenyetso neza.Buri mugari wongeyeho 15m kuburebure ntarengwa.Iyagura ntabwo ihenze cyane cyangwa igoye gukoresha.Ubu ni bwo buryo bwatoranijwe niba ukeneye insinga ndende-ndende mugushiraho kugenekereje, nka OB Van cyangwa umugozi ujya hejuru yinzu hejuru ya umushinga.Iyagura isaba ingufu zaho cyangwa bateri kandi ntibikwiranye nubushakashatsi bugomba kuba mobile.
+ Igisubizo cyiza
+ Urashobora gukoresha insinga ziboneka
- Ukeneye ingufu zaho cyangwa bateri buri burebure
- Ntabwo bikwiranye nigihe kirekire cyogukoresha cyangwa kwishyiriraho mobile
