HDMI cables feem ntau siv thiab tseem ceeb. Qhov twg zoo dua?

 

 

Cov phooj ywg uas feem ntau ua si cov cuab yeej siv video siab paub tias HDMI yog qhov sib cuam tshuam rau cov teeb liab tshaj tawm xov xwm, tab sis HDMI muaj ob peb version HDMI1.4, HDMI2.0, HDMI2.0a, thiab lwm yam, raws li tus neeg tsis nkag siab cov lus qhia cov neeg siv, nws yog qhov nyuaj los xaiv.

 

HDMIyog ib txoj hauv kev tseem ceeb los txuas cov lus txhais multimedia thiab TV. Nov yog qhov digital video / audio interface thev naus laus zis uas tuaj yeem xa cov cim video thiab audio audio tib lub sijhawm tsis muaj digital-rau-analog hloov dua siab tshiab, thiab nws yooj yim heev rau kis cov video thiab audio Signal; video decoding tso zis ntaus ntawv, los ntawm HDMI tuaj yeem xa cov video thiab audio mus rau qhov khoom xa nrog kev ua hauj lwm siab heev, nws tuaj yeem ua haujlwm ntau yam siv hauv cov tshuab multimedia xws li cov TV ntse, cov npov saum txheej, teeb ua haujlwm, thiab lwm yam

 

Hauv ob peb lo lus, Kuv xav qhia keeb kwm ntawm kab no; thawj cov thev naus laus zis uas tau tshwm sim hauv qhov kev hloov xov xwm digital yog DVI siv DHMI. Nrog rau kev tsim cov thev naus laus zis high-txhais audio-visual technology, muaj cov teeb meem ntau dua thiab ntau dua nrog DVI interface, yog li nws koom nrog ntau cov chaw tsim khoom hauv lub tshav kub ntxhov sai xav tau zoo dua cov ntsiab lus video interface technology, uas ua rau kev yug tus qauv HDMI ; nws tuaj yeem pom tau tias qhov kev sib txuas vis dis aus siab txuas ntxiv no tseem yuav ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov khoom siv multimedia yav tom ntej.

 

 

 

HDMI interface yam

 

 

HDMI interfaces tau muab faib ua plaub yam: A, B, C, thiab D.

 

Ntawm lawv, Hom A (Hom A) yog qhov muaj ntau tshaj plaws. Feem ntau lub tiaj tiaj vaj huam sib luag TVs lossis khoom siv yeeb yaj kiab muab cov kev cuam tshuam ntawm qhov loj me no. Hom A muaj 19 pins, qhov dav yog 13.9 hli, thiab tuab ntawm 4.45 hli. Cov cuab yeej siv uas tuaj yeem pom tam sim no 99% yog HDMI cuam tshuam ntawm qhov loj me no.

 

Hom B (Hom B) yog muaj tsawg heev. Nws muaj 29 rab koob thiab dav 21 hli. Qhov xa xov bandwidth yog yuav luag ob zaug loj npaum li cov hom A. Nws yog kiag li "muaj zog" rau kev thov hauv tsev, thiab nws tsuas yog siv nyob rau qee lub sijhawm tshaj lij.

 

Hom C (Hom C) yog tsim rau cov khoom me me. Nws qhov loj me yog 10.42×2.4 hli, uas yog ze li 1/3 me dua ntawm Hom A, thiab nws cov ntawv thov ntau yog tsawg heev.

 

 

 

Hom D (Hom D) yog hom tshiab interface. Qhov loj me me ntxiv txuas ntxiv. Nws adopts ob-kab tus pin tsim. Qhov loj yog zoo li miniUSB interface, uas yog ntau dua haum rau portable thiab hauv tsheb cov khoom siv.

 

 

 

Txawm hais tias qhov cuam tshuam hauv HDMI yuav txawv, cov haujlwm zoo ib yam. Feem ntau, qhov zoo ntawm HDMI interface tsis yog tsawg dua 5000 zaug ntawm ntsaws thiab tshem. Nws tuaj yeem siv rau 10 xyoo thaum ntsaws thiab tshem tawm txhua hnub. Nws yuav tsum tau hais tias nws yog ntau ruaj khov. Nws kuj tseem tsim nyog teev tias HDMI tuaj yeem thim rov qab tau tshaj rau DVI interface. Qee cov khoom qub DVI tuaj yeem txuas los ntawm kev ua lag luam muaj HDMI-DVI cov hloov kho, vim tias DVI kuj tseem siv TMDS txujci. Tom qab cov khoom siv tau txuas nrog, DVI cov khoom siv yuav pom. Tsis muaj CEC (kev tswj hwm cov khoom siv hluav taws xob), nws tsis tuaj yeem lees txais cov cim qhia suab, tab sis nws cia li tsis cuam tshuam qhov kis ntawm cov paib video (grey hloov kho yuav tsum tau), yog li qee tus saib nrog tsuas yog DVI interface kuj tuaj yeem txuas nrog HDMI pab kiag li lawm.

 

 

 

HDMI muaj nuj nqi

 

 

Ntxiv nrog rau ntau hom, tusHDMIinterface kuj sib raug rau cov haujlwm sib txawv.

 

 

Thawj: HDCP 2.2, lub thev naus laus zis no tuaj yeem tiv thaiv cov yeeb yaj kiab digital nqi, TV qhia thiab audio audio los ntawm kev tub sab nyiag txhaum cai thiab luam tawm.

 

Qhov thib ob: HDMI-ARC (Audio Return Channel, suab rov qab) muaj nuj nqi, siv rau kev tsim tawm ntawm TV digital audio, koj tuaj yeem txuas lub amplifier uas tseem pab txhawb ARC muaj nuj nqi, thiab xa cov suab ntawm TV mus rau lub suab txuas ntxiv.

 

Qhov thib peb ib: me ntsis hais txog xim qhov tob. Cov ntsuas phoo dav dav yog 6bit, lub siab 8bit, thiab qhov tshwj xeeb tshaj lij 10bit, uas tuaj yeem nkag siab raws li qhov xim xim tob ntawm 2 txog rau lub zog thib 10, thiab 10bit tshwj xeeb yog hais txog kev siv video coding tshuab uas tuaj yeem muab cov video zoo heev. , muaj peev xwm ntawm kev qhia tshwj xeeb delicacy hauv kev maj mam thiab hloov xim, tab sis cov tseev kom muaj rau kev teeb tsa los ua si 10 ntsis yeej tseem muaj ntau.

 

Thib plaub: MHL thev naus laus zis tsuas siv tsib kab hluav taws xob xa mus txog 4K ultra-siab-txhais tau yooj yim tsis yees duab nrog yim-channel digital audio, thaum tseem them lub xov tooj txawb.

 

 

 
Qhov zoo ntawm HDMI

 

 

1. Ua tau zoo: Lub interface hluav taws xob tsis muaj ib qho poob ntawm analog-rau-digital hloov dua siab tshiab thiab tuaj yeem muab cov video zoo tshaj plaws. Nws yog qhov tshwj xeeb tshaj yog pom ntawm cov kev daws teeb meem siab, xws li 1080p lossis txawm 4K.

 

2. Yooj yim siv: Ib kab sib txuas ua ke ntawm cov cim video thiab ntau lub vev xaib audio audio, uas yog ntau qhov ua tau zoo dua li qhov xwm txheej uas muaj ntau txoj kab sib txuas yav dhau los.

 

3. Kev txawj ntse:HDMItxhawb kev sib txuas lus ntawm ob txoj kev sib txuas ntawm cov khoom siv video thiab cov khoom siv tso tawm tshiab, paub qhov haujlwm tshiab, xws li tsis siv neeg configuration thiab rov ua dua ib zaug. Los ntawm kev siv HDMI, lub cuab yeej cia li xa cov qauv zoo tshaj plaws rau cov khoom sib txuas nrog (piv txwv li, TV txhawb nqa txog 4k30P, HDMI yuav xa cov ntaub ntawv rov qab, thiab lub thawv yuav muab qhov kev daws teeb meem mus rau 4k30P), yog li tus neeg siv tau tsis tas yuav sim teeb tsa nws los ntawm nws tus kheej Txoj Kev Txiav Txim Siab.
