HDMI chiratidzo chakajairwa chiri kushandiswa muhuwandu hwezvinhu zvevatengi.HDMI inomirira High-Definition Multimedia Interface.HDMI chiyero chevaridzi chinoreva kutumira masaini kubva kune kwakabva, senge kamera, Blu-ray player, kana gaming console, kune imwe nzvimbo, senge cheki.Iyo inotsiva zvakananga zviyero zvekare zveanalog senge composite uye S-Vhidhiyo.HDMI yakatanga kuunzwa kumusika wevatengi muna 2004. Kwemakore apfuura, kwave kune akawanda mavhezheni matsva eHDMI, ese ari kushandisa imwechete yekubatanidza.Parizvino, yazvino vhezheni ndeye 2.1, inoenderana ne4K uye 8K resolution uye bandwidths kusvika ku42,6 Gbit/s.
HDMI yakatanga kuitirwa seyero yevatengi, nepo SDI yakasarudzwa seye indasitiri chiyero.Nekuda kweizvi, HDMI natively haitsigire kureba kwetambo refu, kunyanya kana zvigadziriso zvichipfuura 1080p.SDI inogona kumhanya kusvika ku100m mukureba kwetambo mu1080p50/60 (3 Gbit/s), nepo HDMI inogona kutambanudzira kusvika pagumi neshanu muhumwe bandwidth.Pane nzira dzinoverengeka dzekuwedzera HDMI kupfuura iyo 15m.Muchikamu chino, tichataura nezve nzira dzakajairika dzekuwedzera chiratidzo cheHDMI.
Cable Quality
Kana iwe ukapfuura mamita gumi, chiratidzo chinotanga kurasikirwa nemhando yayo.Iwe unogona kuona izvi zviri nyore nekuda kwechiratidzo kusasvika pachiratidziro chekuenda kana zvigadzirwa muchiratidzo chinoita kuti chiratidzo risaonekwe.HDMI inoshandisa tekinoroji inodaidzwa kuti TMDS, kana shanduko-yakaderedzwa kusiyanisa kusaina, kuve nechokwadi chekuti serial data inosvika zvakarongeka.Iyo transmitter inosanganisira yepamberi coding algorithm iyo inoderedza kukanganiswa kwemagetsi pamusoro petambo dzemhangura uye inogonesa kudzoreredza wachi paanogamuchira kuti iwane yakakwira skew kushivirira pakutyaira tambo refu uye mapfupi-anodhura tambo.
Kuti usvike tambo dzehurefu hunosvika 15m, unoda tambo dzemhando yepamusoro.Usarega mutengesi achikunyengedza kutenga tambo dzevatengi dzinodhura kunze uko nekuti nguva zhinji, dzakafanana nedzinodhura.Sezvo HDMI iri chiratidzo chakazara chedhijitari, hapana nzira yekuratidza kuve yemhando yakaderera pane chero imwe tambo.Chinhu chega chinoitika ndechekudonha-kwechiratidzo kana uchitumira masaini akakwira bandwidth pamusoro petambo refu-yakareba kana tambo isina kuverengerwa kune chaiyo HDMI chiyero.
Kana iwe uchida kusvika 15m netambo yenguva dzose, ndapota ona kuti tambo yauri kushandisa yakatemerwa HDMI 2.1.Nekuda kweTMDS, chiratidzo chinosvika zvakanaka kana kuti hachisviki zvachose.Chiratidzo chisina kururama cheHDMI chichava nechaiyo static pamusoro payo, inonzi sparkles.Izvi zvinopenya mapikseli asina kushandurirwa kumashure muchiratidzo chakakodzera uye anoratidzwa muchena.Iyi fomu yekukanganisa kwechiratidzo haiwanzo shongedzo, uye inozonyanya kukonzera dema skrini, pasina chiratidzo zvachose.
Kuwedzera HDMI
HDMI yakagamuchirwa nekukurumidza seyakanyanya interface yekutakura vhidhiyo uye odhiyo mumhando dzese dzezvigadzirwa zvevatengi.Nekuti HDMI inotakurawo odhiyo, yakakurumidza kuve chiyero chemapurojekita uye mahombe skrini mumakamuri emusangano.Uye nekuti DSLRs uye vatengi-giredhi makamera zvakare ane HDMI interfaces, nyanzvi dzevhidhiyo mhinduro dzakagamuchira HDMI zvakare.Sezvo ichigamuchirwa zvakanyanya senge interface uye ichiwanikwa pane yakaringana chero mutengi LCD pani, inodhura zvakanyanya-inoshanda kushandisa mukumisikidzwa kwevhidhiyo.Mukumisikidzwa kwevhidhiyo, vashandisi vakawira mudambudziko rekuti kureba kwetambo kwaigona kungove 15m.Pane nzira dzakawanda dzekupedza dambudziko iri:
Shandura HDMI kuSDI uye kumashure
Paunoshandura chiratidzo cheHDMI kuita SDI uye kudzoka kunzvimbo yekuenda, iwe unonyatso wedzera chiratidzo kusvika ku130m.Iyi nzira yakashandisa kureba kwetambo padivi rekutapurirana, yakashandurwa kuita SDI, yakashandisa iyo yakazara tambo urefu hwe100m, uye yakadzoserwa kumashure mushure mekushandisa yakazara-yakareba HDMI tambo zvakare.Iyi nzira inoda yemhando yepamusoro SDI tambo uye maviri anoshanda anoshandura uye haafarire nekuda kwemutengo.
+ SDI tekinoroji yakasimba kwazvo
+ Inotsigira anosvika 130m uye mberi kana uchishandisa mabheji matsvuku
- SDI mumhando yepamusoro yevhidhiyo ye4K haina kudhura zvakanyanya
- Active converters inogona kudhura
Shandura kuHDBaseT uye kumashure
Paunoshandura chiratidzo cheHDMI kuita HDBaseT, uye kumashure unogona kusvika kureba kwetambo pamusoro peinodhura-inoshanda CAT-6 kana nani tambo.Iyo chaiyo chaiyo kureba inosiyana pane iyo hardware yaunoshandisa, asi kazhinji yenguva, 50m + inogoneka.HDBaseT inogona zvakare kutumira simba kumudziyo wako kuti usade simba remunharaunda kune rimwe divi.Zvakare, izvi zvinoenderana nehardware inoshandiswa.
+ HDBaseT tekinoroji yakasimba kwazvo ine rutsigiro rwekusvika ku4K resolution
+ HDBaseT inoshandisa inodhura-inoshanda cabling muchimiro cheCAT-6 ethernet tambo
- Ethernet tambo yekubatanidza (RJ-45) inogona kusasimba
-Urefu hwetambo hwepamusoro zvichienderana nehardware inoshandiswa
Shandisa Active HDMI Cables
Active HDMI tambo tambo dzine yakavakirwa-mukati inoshandura kubva kumhangura yenguva dzose kuenda kune optical fiber.Nenzira iyi, tambo chaiyo ndeye skinny optical fiber murubha insulation.Iyi mhando yetambo yakakwana kana iwe uchida kuiisa mune yakagadziriswa yekuisa, senge chivako chehofisi.Tambo yacho haina kusimba uye haikwanise kukotama pane imwe radius, uye haifanirwe kutsikwa kana kufambiswa nengoro.Mhando iyi yekuwedzera inodhura kure asi yakavimbika zvakanyanya.Mune zvimwe zviitiko, imwe yetambo inopera haina simba kumusoro nekuda kwechishandiso chisiri kuburitsa voltage inodiwa kune vanoshandura.Aya mhinduro anokwira kusvika ku100 metres zviri nyore.
+ Active HDMI tambo natively inotsigira yakakwirira resolution kusvika ku4K
+ Yakaputsika uye yakareba cabling mhinduro yekumisikidza yakagadziriswa
-Optical fiber tambo haina kusimba pakukotama uye kupwanya
-Haasi ese anotaridza kana ma transmitters anoburitsa iyo chaiyo voltage yetambo
Shandisa Active HDMI Extenders
Active HDMI extenders inzira yakanaka yekuwedzera chiratidzo chinodhura-zvinobudirira.Imwe neimwe extender inowedzera imwe 15m kusvika pakureba kwepamusoro.Aya ekuwedzera haana kudhura zvakanyanya kana kunetsa kushandisa.Iyi ichave nzira inosarudzika kana iwe uchida tambo dzepakati-kureba mune yakamisikidzwa kuisirwa, senge OB Van kana tambo inoenda pamusoro pesirin'i kune purojekita.Aya ekuwedzera anoda simba remunharaunda kana bhatiri uye haakodzeri kumisikidzwa inoda nharembozha.
+ Inodhura-inoshanda mhinduro
+ Inogona kushandisa tambo dziripo kare
- Inoda simba remunharaunda kana bhatiri kureba kwetambo yega yega
- Haina kukodzera kumhanyisa tambo refu kana kuisirwa nhare
