High-Definition Multimedia Interface (interface rau high-txhais Multimedia) tuaj yeem pom muaj ntau yam khoom siv. Lub npe ntawm lub npe no yog paub zoo thiab ntau. HDMI, uas yog lub ntsiab lus tseeb rau kev sib txuas cov multimedia khoom uas txhawb nqa cov zauv ntau tshaj tawm (ntawm FullHD thiab siab dua). Lub connector rau nws yuav ntsia tau rau hauv ib daim video, saib, SmartTV thiab lwm yam khoom muaj peev xwm ntawm tso duab rau ntawm koj qhov screen.
Cov kab mob HDMI yog dab tsi?
HDMI feem ntau yog siv los txuas rau cov khoom siv hauv tsev: cov high-resolution panels, televisions, video cards thiab laptops - tag nrho cov cuab yeej no yuav muaj qhov chaw nres nkoj hauv HDMI. Xws li cov koob npe thiab kev txhawb pab yog muab los ntawm cov ntaub ntawv xa mus rau siab, thiab tsis tuaj yeem cuam tshuam thiab suab nrov. Nyob rau hauv tsab xov xwm no, peb yuav tham txog hom HDMI cables, hom kev sib txuas, thiab nyob rau lub sijhawm zoo li cas los siv ib los yog lwm hom lawv.
Hom kev connectors
Hnub no, tsuas muaj tsib hom HDMI cable connectors xwb. Lawv tau cim nrog Latin cov tsiaj ntawv ntawm A rau E (A, B, C, D, E). Peb feem ntau yog siv: Puv loj (A), Mini loj (C), Micro loj (D). Xav txog txhua yam uas tau muaj nyob rau hauv ntau dua:
- Hom A yog qhov ntau tshaj plaws, txuas rau nws tuaj yeem nyob rau hauv phaib, laptops, TVs, game consoles thiab lwm yam khoom siv ntau hom.
- Hom C tsuas yog ib qho me me ntawm hom A. Nws tau nruab rau hauv cov khoom me me - cov xov tooj, ntsiav tshuaj, PDAs.
- Hom D yog qhov tsawg tshaj plaws ntawm HDMI. Kuj tseem siv me me, tab sis ntau zaus tsawg dua.
- Hom B yog tsim los ua haujlwm nrog cov qauv loj loj (3840 x 2400 pixels, uas yog plaub zaug ntau tshaj tag nrho HD), tiam sis tseem tsis tau thov - tos hauv tis nyob rau yav tom ntej.
- Ntau yam hauv qab ntawm E cim yog siv los txuas rau multimedia devices rau tsheb xov xwm chaw.
Cov connectors tsis sib xws.
Cov hom ciav hlau
Yog ib tus biggest confusions nrog HDMI interface yog cov coob ntawm nws cov specifications. Tam sim no muaj 5 ntawm lawv, qhov kawg ntawm lawv - HDMI 2.1 tau pib thaum xaus rau lub Kaum Ib Hlis 2017. Tag nrho cov specifications yog sib npaug, tab sis cov connectors hauv lub cable tsis. Pib ntawm cov lus qhia 1.3 lawv tau muab faib ua ob pawg: Txuj thiab Kev kub ceev. Lawv txawv hauv lub teeb liab zoo thiab bandwidth.
Xav tias muaj ntau ntau cov qauv qhia uas tau khaws tseg thiab tswj xyuas - qhov no yog ib qho kev tshwm sim zoo tiag tiag, thaum ib lub tshuab muaj ntau xyoo, muaj kev txhim kho thiab txais kev ua haujlwm tshiab. Tab sis nws yog qhov tseem ceeb kom nco ntsoov qhov tseeb uas ntxiv rau qhov no muaj 4 hom kab txuas, uas yog sharpened rau kev khiav hauj lwm ua tej yam dej num. Yog hais tias lub HDMI cable tsis haum rau cov haujlwm uas nws tau yuav, ces qhov no yuav fraught nrog failures thiab cov tsos ntawm artifacts thaum hloov ntawm cov duab, desynchronization suab thiab duab.
Hom HDMI cables:
- Txheem HDMI Cable - kev xaiv nyiaj siv, tsim rau kev sib kis video hauv HD thiab FullHD zoo (nws cov zaus yog 75 MHz, bandwidth yog 2.25 Gbit / s, uas sib raug raws li cov kev cai no). Siv cov DVD players, satellite receivers, plasmas thiab televisions. Zoo meej rau cov neeg uas tsis xav tau cov duab zoo thiab muaj suab zoo.
- Txheem HDMI Cable nrog Ethernet - yog tsis sib txawv ntawm tus qauv kab, tshwj tsis yog tias muaj cov ntaub ntawv qhia txog cov ntaub ntawv hloov channel Channel Ethernet HDMI, cov ntaub ntawv txauv ntawm cov ntaub ntawv uas muaj peev xwm ncav cuag 100 Mb / s. Cov kab no muaj kev sib txuas hauv high-speed Internet thiab muab lub peev xwm los faib cov ntsiab lus tau txais los ntawm lub network mus rau lwm cov khoom txuas nrog ntawm HDMI. Kev Rov Rov Qab yog txhawb, uas tso cai rau cov ntaub ntawv tawm suab tsis tau siv cov cables ntxiv (S / PDIF). Txheem kab ntawv tsis txhawb cov tshuab no.
- Kev kub ceev HDMI Cable - muab ib txoj kab dav dav rau kev xa xov xwm. Nrog nws, koj tuaj yeem hloov tau ib daim duab nrog kev daws teeb meem txog li 4K. Txhawb txhua video ntaub ntawv tawm tswv yim, zoo li 3D thiab sib sib zog nqus xim. Siv hauv Blu-duab tshav ntuj, HDD-players. Nws muaj qhov siab tshaj plaws tshiab ntawm 24 Hz thiab ib tug bandwidth ntawm 10.2 Gbit / s - qhov no yuav txaus rau saib cov tsos, tab sis, yog tias koj xa ntas los ntawm kev siv computer nrog kev siab tus nqi hla lub cable, nws yuav tsis zoo heev, vim hais tias cov duab yuav zoo li ragged thiab qeeb heev.
- Kev kub ceev HDMI Cable nrog Ethernet - tib yam li High Speed HDMI Cable, tab sis kuj qhia high-speed Internet access HDMI Ethernet - txog li 100 Mb / s.
Tag nrho cov specifications, tshwj Standard HDMI Cable, txhawb ARC, uas tshem tawm qhov xav tau rau ib lub suab ntxiv.
Cable ntev
Hauv khw muag khoom feem ntau muag cables mus txog 10 meters. Ib tus neeg siv yuav zoo dua li txaus kom muaj 20-meter, qhov kev lag luam uas yuav tsum tsis yooj yim. Hauv cov lag luam loj, raws li hom databases, IT-centers, koj yuav tsum tau cords li 100 meters ntev, thiaj li hais tias "nrog ib tug ntug". Siv HDMI hauv tsev yog li 5 los sis 8 meters.
Cov kab txawv tsim rau kev muag khoom mus rau cov neeg siv tau yooj yim yog ua los ntawm kev qhia tshwj xeeb uas tau npaj tooj liab, uas tuaj yeem kis tau cov ntaub ntawv ntawm cov sijhawm tsis muaj kev cuam tshuam thiab cuam tshuam. Txawm li cas los, qhov zoo ntawm cov ntaub ntawv uas tau siv rau hauv kev tsim, thiab nws cov thickness yuav zoo heev rau kev ua tau zoo ntawm kev ua hauj lwm tag nrho.
Ntev cables ntawm no interface yuav ua tau siv:
- Twisted khub - xws li ib tug hlau yog peev xwm kis tau ib lub teeb liab dhau 90 m ntsuas yam tsis tau ua kom muaj kev cuam tshuam lossis cuam tshuam. Nws yog zoo dua tsis yuav xws li ib tug cable ntau tshaj li 90 meters nyob rau hauv ntev, vim hais tias qhov zaus thiab zoo ntawm cov ntaub ntawv xa mus tau ua tau zoo heev distorted.
- Coaxial cable - muaj nyob rau hauv nws tsim sab nraud thiab central conductor, uas yog sib cais los ntawm ib tug txheej ntawm rwb thaiv tsev. Cwj pwm ua tau zoo ntawm tooj liab. Muab cov teeb meem zoo tshaj plaws hauv kev xa xov mus txog rau 100 meters.
- Fibre - qhov tseem kim tshaj plaws thiab txuag ntawm cov kev xaiv saum toj no. Nrhiav kev lag luam no yuav tsis yooj yim, vim tsis muaj qhov kev thov zoo tshaj plaws rau nws. Transmits ib lub teeb liab mus rau ib tug deb ntawm ntau tshaj 100 meters.
Xaus
Cov khoom no tshuaj xyuas cov khoom ntawm cov kab mob HDMI, xws li hom txuas, kab hom thiab nws qhov ntev. Cov ntaub ntawv kuj tau muab rau ntawm bandwidth, qhov zaus ntawm cov ntaub ntawv xa mus rau cable thiab nws lub hom phiaj. Peb cia siab tias qhov tsab xov xwm no yog qhov tseem ceeb thiab ua rau nws muaj peev xwm kawm tau ib yam tshiab rau koj tus kheej.
