Mwamba-Definition Multimedia Interface (mawonekedwe a multimedia yapamwamba) angapezeke muzinthu zosiyanasiyana. Tsatanetsatane wa dzina ili ndidziwika bwino komanso yodziwika bwino. HDMI, yomwe ndi yoyenera kugwirizanitsa zipangizo zamagetsi zomwe zimathandiza kwambiri kutanthauzira chithunzi chithunzi (kuchokera ku FullHD ndi apamwamba). Chojambulira cha izo chikhoza kukhazikitsidwa mu khadi la kanema, kufuula, SmartTV ndi zipangizo zina zomwe zingathe kusonyeza chithunzi pazenera lanu.
Kodi ndi zingati za HDMI?
HDMI imagwiritsidwa ntchito makamaka kugwirizanitsa zipangizo zamakono: mapangidwe apamwamba, makanema, makhadi a kanema ndi laptops - zipangizo zonsezi zingakhale ndi khomo la HDMI. Kutchuka ndi kufalikira kotereku kumaperekedwa ndi kuchuluka kwa mlingo wa deta, komanso kusowa kwa kupotoka ndi phokoso. M'nkhaniyi, tikambirana za mitundu ya ma CDMI, mitundu yothandizira, ndipo ndi nthawi ziti zomwe zingakhale bwino kugwiritsa ntchito mtundu umodzi kapena wina.
Mitundu yolumikizana
Masiku ano, pali mitundu isanu yokha ya ojambulira chingwe cha HDMI. Amadziwika ndi zilembo zachilatini kuchokera ku A mpaka E (A, B, C, D, E). Zitatu zimagwiritsidwa ntchito: Kukula Kwambiri (A), Mini Size (C), Micro Size (D). Ganizirani chilichonse chomwe chilipo mwatsatanetsatane:
- Lembani A ndilo lofala kwambiri, zolumikizira zake zingapezeke pa makadi a kanema, laptops, ma TV, masewera a masewera ndi zipangizo zina zamagetsi.
- Mtundu C ndi mtundu wochepa chabe wa mtundu A. Umayikidwa mu zipangizo zazing'ono zazikulu - mafoni, mapiritsi, PDAs.
- Mtundu D ndi mitundu yochepa kwambiri ya HDMI. Amagwiritsidwanso ntchito mu zipangizo zing'onozing'ono, koma mocheperapo.
- Mtundu B unakonzedwa kugwira ntchito ndi ziganizo zazikulu (3840 x 2400 pixels, zomwe nthawi zinayi kuposa HD Full), koma sizinagwiritsidwe ntchito - kuyembekezera m'mapiko mu tsogolo losangalatsa.
- Zosiyanasiyana pansi pa zolemba za E zimagwiritsidwa ntchito kugwirizanitsa zipangizo zamagetsi kuzipangizo zamagalimoto.
Zogwirizana sizigwirizana.
Mitundu yachitsulo
Chimodzi mwazovuta kwambiri ndi HDMI mawonekedwe ndi chiwerengero chake chachikulu. Tsopano pali asanu mwa iwo, omalizira awo - HDMI 2.1 adayambitsidwa kumapeto kwa November 2017. Mafotokozedwe onse ali ovomerezana wina ndi mzake, koma ogwirizana mu chingwe alibe. Kuyambira pazokambirana 1.3 iwo anagawa m'magulu awiri: Standart ndi Kuthamanga kwakukulu. Zimasiyana ndi khalidwe la chizindikiro ndi chiwongolero.
Tiyerekeze kuti pali mfundo zambiri zomwe zimasungidwa ndi kusungidwa - izi ndizodabwitsa, pamene teknoloji imodzi yakhalapo kwa zaka zambiri, ikukula ndikupeza ntchito zatsopano. Koma nkofunika kukumbukira mfundo kuti kuwonjezera pa izi pali mitundu 4 ya chingwe, zomwe zimalowedwera kuti zigwire ntchito zina. Ngati chingwe cha HDMI sichigwirizana ndi ntchito yomwe idagulidwa, ndiye kuti izi zingakhale zolephereka ndi maonekedwe a zojambula panthawi yosamutsa zithunzi, kutulutsa mawu ndi chithunzi.
Mitundu ya zipangizo za HDMI:
- Wowonjezera HDMI Cable - njira yopangira bajeti, yokonzekera mavidiyo pa HD ndi FullHD quality (maulendo ake ndi 75 MHz, bandwidth ndi 2.25 Gbit / s, zomwe zikugwirizana ndi zisankho izi). Zimagwiritsidwa ntchito pa osewera DVD, ma TV, satema ndi ma TV. Zokwanira kwa iwo omwe safunikira chithunzi chokwanira ndi phokoso lapamwamba.
- Wowonjezera HDMI Cable ndi Ethernet - sali wosiyana ndi chingwe chophatikizira, kupatulapo kukhalapo kwa njira yodutsa deta Ethernet HDMI, mlingo wa kusinthana kwa deta womwe ukhoza kufika pa Mbali 100 Mb / s. Chingwechi chimapereka ma intaneti mofulumira kwambiri ndipo chimapereka mphamvu yogawira zomwe zilipo kuchokera ku intaneti kupita ku zipangizo zina zogwirizana ndi HDMI. Pulogalamu ya Audio Return imathandizidwa, yomwe imalola kuti ma CD amvetsere popanda kugwiritsa ntchito zingwe zina (S / PDIF). Kawuni yapamwamba sichirikiza tekinoloje iyi.
- Kuthamanga Kwambiri HDMI Cable - amapereka njira yowonjezera yotumizira uthenga. Ndicho, mutha kusintha fano ndi chisankho cha 4K. Imathandizira mafayilo onse ojambula mavidiyo, komanso 3D ndi Deep Color. Amagwiritsa ntchito Blu-ray, HDD-osewera. Ili ndi mlingo wokwanira wotsitsimutsa wa Hz 24 ndi bandwidth wa 10.2 Gbit / s - izi zikwanira kuwonera mafilimu, koma ngati mutumiza mafelemu kuchokera ku masewera a pakompyuta ndi mlingo wapamwamba pa chingwe, siziwoneka bwino, chifukwa chithunzicho chidzakhala zimawoneka ngati zowopsya komanso zochedwa kwambiri.
- Kuthamanga Kwambiri HDMI Cable ndi Ethernet - mofanana ndi High Speed HDMI Cable, komanso imapereka Intaneti mofulumira kwambiri HDMI Ethernet - mpaka 100 Mb / s.
Zonse zofotokozera, kupatula pa Cable HDMI Cable, support ARC, zomwe zimathetsa kufunikira kwa chingwe chowonjezera audio.
Kutalika kwa waya
M'misika nthawi zambiri zimagulitsidwa zingwe mpaka mamita 10. Wogwiritsa ntchito wamba adzakhala wochuluka kwambiri kuti akhale ndi mamita 20, zomwe siziyenera kukhala zovuta kupeza. Pa mabungwe akuluakulu, malingana ndi mtundu wa zolemba, IT-malo, mungafunikire zingwe mpaka mamita 100 m'litali, kotero kuti "pambali". Kugwiritsa ntchito HDMI kunyumba nthawi zambiri kumakhala mamita 5 kapena 8.
Zosintha zomwe zimagulitsidwa kwa ogwiritsa ntchito wamba zimapangidwa ndi mkuwa wokhazikika, womwe ungatumize uthenga paulendo wautali popanda kusokoneza ndi kusokoneza. Komabe, ubwino wa zipangizo zomwe zinagwiritsidwa ntchito m'chilengedwe, ndi makulidwe ake zingakhudze momwe ntchitoyo ikugwirira ntchito.
Zingwe zamkati za mawonekedwe awa zingapangidwe pogwiritsa ntchito:
- Gulu lopotoka - waya wotere amatha kutumiza chizindikiro pamtunda wa mamita 90 popanda kuwonetsa kapena kusokoneza. Ndibwino kuti musagule chingwe chotere kuposa mamita 90 m'litali, chifukwa maulendo ndi maulendo a deta yopatsirana akhoza kusokonezedwa kwambiri.
- Chingwe cha Coaxial - chili ndi kapangidwe kamene kali kunja ndi pakati, kamene kamasiyanitsidwa ndi kapangidwe ka kusungunula. Otsogolera amapangidwa ndi mkuwa wapamwamba. Amapereka mauthenga abwino kwambiri pa chingwe mpaka mamita 100.
- Zitsulo - zokwera mtengo komanso zogwira mtima zomwe mungasankhe pamwambapa. Pezani kugulitsa koteroko sikudzakhala kophweka, chifukwa palibe chofunika kwambiri. Kutumiza chizindikiro kwa mtunda wa mamita oposa 100.
Kutsiliza
Nkhaniyi idasanthula zipangizo za HDMI, monga mtundu wa chojambulira, mtundu wa chingwe ndi kutalika kwake. Chidziwitso chinaperekedwanso pamtunduwu, kutuluka kwa deta pa chingwe ndi cholinga chake. Tikukhulupirira kuti nkhaniyi inali yothandiza ndipo inachititsa kuti muphunzire zina zatsopano.
