Isixhumanisi se-High-Definition Multimedia (isikhombimsebenzisi se-multimedia ephezulu) singatholwa emadivayisini ahlukahlukene. Isifinyezo saleli gama liyaziwa futhi livamile. I-HDMI, okuyinto ejwayelekile yokuxhuma imishini ye-multimedia esekela okuphezulu okushicilelwe kwesithombe (kusuka ku-FullHD nangaphezulu). Isixhumi salo singasetshenziswa ekhadini levidiyo, ukuqapha, i-SmartTV namanye amadivayisi afanele ukubonisa isithombe esikrinini sakho.
Yiziphi izintambo ze-HDMI
I-HDMI isetshenziswe ngokuyinhloko ukuxhuma imishini yasendlini: amaphakheji aphezulu okuxazulula, amathelevishini, amakhadi wevidiyo nama-laptops - wonke lawa madivayisi angase abe ne-HDMI port. Ukudumala okunjalo nokusabalalisa kunikezwa izinga eliphezulu lokudlulisa idatha, kanye nokungabikho kokuphazamiseka nomsindo. Kulesi sihloko, sizokhuluma ngezinhlobo zezintambo ze-HDMI, izinhlobo zezixhumi, futhi yiziphi izimo okungcono ukusebenzisa zona noma ezinye izinhlobo zazo.
Izinhlobo zezixhumi
Namuhla, kunezinhlobo ezinhlanu kuphela zezingxube zekhebula ze-HDMI. Amakwe ngamagama aseLatini avela ku-A kuya ku-E (A, B, C, D, E). Amatsatfu asetshenziswa kakhulu: Usayizi ogcwele (A), Usayizi wamancane (C), Micro Size (D). Cabanga ngalunye lwezinto ezikhona ngokuningiliziwe:
- Thayipha A yiyona evame kakhulu, izixhumi zayo zingatholakala kumakhadi wevidiyo, ama-laptops, ama-TV, ama-console ezemidlalo namanye amadivayisi we-multimedia.
- Uhlobo C luyinguqulo encane nje yohlobo A. Lufakwe emadivaysi amancane amancane - amafoni, amaphilisi, ama-PDA.
- Thayipha D yizinhlobonhlobo ezincane kakhulu ze-HDMI. Futhi isetshenziswe kumadivayisi amancane, kodwa kaningi kakhulu.
- Uhlobo B lwaklanyelwe ukusebenza ngezinqumo ezinkulu (ama-pixel angu-3840 x 2400, okuphindwe izikhathi ezine ngaphezu kwe-HD Full), kodwa engakafakwa - ukulinda emaphikweni esikhathini esizayo.
- Izinhlobonhlobo ngaphansi kokumaka kwe-E zisetshenziselwa ukuxhuma amadivaysi e-multimedia kumaziko wemidiya yemidiya.
Izixhumi azihambisani.
Izinhlobo zekhebula
Enye yezingxabano ezinkulu nge-HDMI isikhombikubona yinani elikhulu lezincazelo zalo. Manje kukhona okungu-5 kubo, okugcina kwabo - i-HDMI 2.1 eyethulwa ekupheleni kukaNovemba 2017. Zonke izinkomba zihambisana nomunye nomunye, kodwa izixhumi ku-ikhebula azikho. Kusukela ekushicileleni 1.3 bahlukaniswe ngezigaba ezimbili: Standart futhi Isivinini esikhulu. Ihlukahluka kukhwalithi yesignali nokuhamba komkhawulokudonsa.
Ake sithi kunezincazelo eziningana ezijwayelekile ezigcinwa futhi zigcinwe - lokhu kuyinto evamile kakhulu, lapho ubuchwepheshe obukhona bukhona iminyaka eminingi, buyathuthuka futhi buzuza imisebenzi emisha. Kodwa kubalulekile ukukhumbula engqondweni ukuthi ngaphezu kwalokhu kunezinhlobo ezine zekhebula, ezibukhali ukuze zisebenze ukwenza imisebenzi ethile. Uma ikhebula le-HDMI lingavumelani nomsebenzi owathengiwe ngawo, lokhu kungase kuphelelwe ukuhluleka nokubukeka kwempahla ngesikhathi sokudluliswa kwezithombe, ukuchithwa kwemisindo nesithombe.
Izinhlobo zezintambo ze-HDMI:
- Ikhebula le-HDMI elijwayelekile - inketho yebhajethi, eyenzelwe ukuhanjiswa kwevidiyo ku-HD ne-FullHD ikhwalithi (imvamisa yayo ingu-75 MHz, umkhawulokudonsa u-2.25 Gbit / s, ohambisana nalezi zinqumo). Isetshenziselwa abadlali be-DVD, abamukeli be-satellite satellite, ama-plasma namathelevishini. Ilungele kulabo abangadingi isithombe esicacisiwe kanye nekhwalithi ephezulu.
- Ikhebula le-HDMI elijwayelekile ne-Ethernet - ayifani nekhebula elijwayelekile, ngaphandle kokuthi kube khona isiteshi sokudlulisa idatha se-bi-direction Ethernet HDMI, isilinganiso sokushintshaniswa kwedatha esingasifinyelela ku-100 Mb / s. Le cord inikeza uxhumano lwe-intanethi oluphezulu futhi lunikeza ikhono lokusabalalisa okuqukethwe okutholiwe kusuka kwinethiwekhi kuya kwamanye amadivayisi axhunyiwe nge-HDMI. I-Back Return Channel isekelwe, evumela ukuthi idatha yomsindo idluliswe ngaphandle kokusetshenziswa kwezintambo ezengeziwe (S / PDIF). Ikhebula elijwayelekile alisekeli lobu buchwepheshe.
- Ikhebula eliphezulu le-HDMI - inikeza isiteshi esikhulu sokwedlulisa ulwazi. Ngalo, ungadlulisela isithombe ngesinqumo se-4K. Usekela wonke amafomethi wefayela levidiyo, kanye ne-3D ne-Deep Color. Isetshenziswa kuma-Blu-ray, abadlali be-HDD. Inesilinganiso esiphezulu sokuvuselela ama-Hz angu-24 no-bandwidth we-10.2 Gbit / s - lokhu kuzokwanela ukubukela ama-movie, kodwa uma uthumela amafomu kusuka kumdlalo wekhompyutha enezinga eliphezulu lohlaka phezu kwekhebula, ngeke libukeke kahle, ngoba isithombe sizobe kubonakala sengathi idlwengulwe futhi iphuza kakhulu.
- Ikhebula eliphezulu le-HDMI le-Ethernet - kufana nekhredithi ye-High Speed HDMI, kodwa futhi inikeza ukufinyelela kwe-intanethi ye-HDMI Ethernet ngesivinini esikhulu-kufika ku-100 Mb / s.
Konke okucacisiwe, ngaphandle kwekhaneli ejwayelekile ye-HDMI, i-ARC yokusekela, okuqeda isidingo sekhebula elilalelwayo.
Ubude bekhamera
Ezitolo ezithengiswa kakhulu izintambo ezifika kumamitha angu-10. Umsebenzisi ojwayelekile uzoba ngaphezu kokwanele ukuba abe nemitha engama-20, okungekho okumele kube nzima. Emabhizinisini amakhulu, ngokusho kohlobo lwama-database, izikhungo ze-IT, ungadinga izintambo kuze kube ngamamitha ayi-100 ngobude, ngakho-ke uthi "nge-margin". Ukusebenzisa i-HDMI ekhaya ngokuvamile kuvame ama-5 noma amamitha ayi-8.
Izinhlobonhlobo ezidalwe ukudayiswa kubasebenzisi abajwayelekile zenziwe ngethusi elilungiselelwe ngokukhethekile, elingadlulisa ulwazi emadolobheni amancane ngaphandle kokuphazanyiswa nokuphazamiseka. Noma kunjalo, izinga lezinto ezisetshenziselwa ukudalwa, futhi ukuqina kwalo kungathinta kakhulu ukusebenza komsebenzi wonkana.
Amakhodi amakhulu ale interface angenziwa ngokusebenzisa:
- Umbhangqwana ophikisiwe - ucingo olunjalo luyakwazi ukudlulisela isignali ngaphezu kwamamitha angu 90 ngaphandle kokwenza noma yikuphi ukuphazamiseka noma ukuphazanyiswa. Kungcono ukuthi ungathengi ikhebula elinjalo ngaphezu kwamamitha angu-90 ubude, ngoba imvamisa kanye nekhwalithi yedatha ehanjisiwe ingaphazamiseka kakhulu.
- Ikhamera yeCoaxial - iqukethe umklamo wayo wangaphandle nomphakathi, ohlukaniswa ngendwangu yokugxila. Abaqhubi benziwa ngethusi eliphakeme kakhulu. Inikeza ukudluliswa kwesignali ezinhle kakhulu ku-cable kuze kube ngamamitha ayi-100.
- I-Fiber - eyona ebiza kakhulu futhi ephumelelayo yezinketho ezingenhla. Thola ukuthengiswa okunjalo ngeke kube lula, ngoba akukho isidingo esikhulu. Idlulisela isignali ebangeni lamamitha angaphezu kuka-100.
Isiphetho
Lezi zinto zihlolisise izindawo zezintambo ze-HDMI, ezifana nohlobo lwenethiwekhi, uhlobo lwekhebula nobude balo. Ulwazi lunikezwe futhi kumkhawulokudonsa, imvamisa yokudluliswa kwedatha phezu kwekhebula nenhloso yalo. Sithemba ukuthi lesi sihloko sasiwusizo futhi senze sikwazi ukufunda okuthile okusha.
