Izixazululo ezinamasondo nezintambo zokukhulisa i-HDMI ibanga lokuxhumana
Yithande noma uyayizonda - I- HDMI manje isilinganiso esizenzakalelayo sokuxhuma izingxenye zendawo yaseshashalazini.
I-HDMI - Isibusiso Nesiqalekiso
Into enhle nge-HDMI ukuthi ungadlulisa kokubili umsindo nevidiyo kusuka emthonjeni (njenge-Blu-ray Disc player) ukuya endaweni ethile (njengokwamukela isithandwa sekhaya noma i-TV) usebenzisa ikhebula elilodwa. Kodwa-ke, i-HDMI inezinkinga zayo, njengezinkinga ezithile ngezikhathi ezithile ezivela "ekuthintweni" kokubambisana kwayo nokuthi kukhona izinguqulo eziningana ze-HDMI ezinquma ukuthi yiziphi izici ezingatholakala, kanye nokwahlukana kulokho abakhiqizi banquma ukunikeza noma ukunganikezeli ngokuqondile version.
Kodwa-ke, inkinga eyodwa eyengeziwe nge-HDMI yukuthi akuhlali njalo isebenza emadolobheni amade. Kunconywa ukuthi amadivaysi omthombo we-HDMI nezindawo zokungena azungeze ngaphezulu kwamamitha angu-15 ukuze abe nomphumela omuhle kakhulu, kodwa kunezintambo ze-HDMI ezitholakalayo ezingakwazi ukunweba lokhu ngokuthembekile kuya kumamitha angu-30 - futhi, uma zakhiwe kahle kusho ukuthi kubiza ama-ultra), kunezintambo ze-HDMI ezingakwazi ukunweba ubuqotho besignali kuze kufike kumamitha angu-50.
Noma kunjalo, lokhu kungaba yinto ekhohlisayo njengoba ungase uqale ukubona umphumela owaziwa ngokuthi "u-sparkles" futhi ungase ubhekane nezinkinga ezithintekayo zokubamba ngesandla. Ngakolunye uhlangothi, ungase uhlangabezane nalezi zinkinga ngisho nangama-cable emfushane we-HDMI.
Ngakho-ke, wenzenjani uma ufuna ukwandisa lelo banga ukuya ezingaphezu kwamamitha angama-50 noma kude nje njengamamitha angu-100 ukuya kwangu-300, noma ngisho ucingo yonke indlu yakho ukuze amadivaysi e-HDMI angabonwa futhi afakwe ezindaweni eziningi?
I-HDMI Ngaphezulu Kwenkambu
Isixazululo esisodwa ukusebenzisa izintambo ze-Ethernet njengengxenye yesisombululo. Uhlobo olufanayo lwezintambo ze-Ethernet Cat5, 5e, 6, kanye ne-Cat7 ezisetshenziselwa ukuxhuma amadivaysi kwi-intanethi router noma i-home / office network ingasetshenziselwa ukudlulisela amasignali alalelwayo / amavidiyo asetshenziselwa ukusethwa kweshashalazi yasekhaya.
Indlela okwenziwa ngayo usebenzisa izintambo ze-ethernet ngokusebenzisa i-converter HDMI-to-Cat5 (5e, 6,7). Ukuze uthole kabanzi mayelana nalesi sxazululo sokuxhumeka kwe-HDMI, funda izibuyekezo ezimbili zangaphambilini ngibhale ngemikhiqizo emibili eguquguqukayo ye-HDMI-to-Cat evela ku- Accell ne-Atlona enikeza izibonelo zohlu olulodwa lomkhiqizo ongasetshenziselwa ukuxhuma ukugijima kwekhebula le-HDMI.
Ngaphezu kokukhethwa kokuguqula i-HDMI ku-Cat5e, 6, noma ku-7 ukuze uthumele izimpawu ngaphezu kwamabanga amade, ezinye izixazululo zifaka i-HDMI ngaphezu kwe-Fiber ne-HDMI phezu kwe-Coax. Ukuhlelwa komzimba okufanayo, umthombo we-HDMI uxhunywe "kumthumeli, oguqula isignali ye-HDMI ku-Fiber noma i-Coax, ebuye ixhunywe" kumamukeli "oguqula isignali ezayo ngaphezu kweFiber noma Coax emuva ku-HDMI.
Izixazululo ezingenantambo - i-HDMI engenamakhebuli
Enye indlela yokuxhuma amadivaysi e-HDMI uyayenza ngaphandle kwentambo. Nakuba le ndlela ayinamandla noma ingakwazi ukusingatha amabanga amade kakhulu - ingakwazi ukuqeda isidingo sekhebula elide le-HDMI ngaphakathi ekamelweni elikhulu, ngokuvamile lide lingamamitha angu-30 ukuya kwangu-60, kodwa amanye amayunithi anganikela kuze kube ngu-100 Ukufakwa kokungena.
Indlela yokuxhumeka kwe-HDMI engenantambo isebenza ukuthi uxhuma ikhebula elifushane le-HDMI ekukhishwe kwe-HDMI yedivayisi yomthombo (Blu-ray Player, Media Streamer, Cable / Satellite Box) kumthumeli wangaphandle othumela isignali yomsindo / yevidiyo ngokungenawo i-receiver, ukuthi, futhi, ixhunywe ku-TV noma iprojekti yevidiyo isebenzisa ikhebula elifushane le-HDMI.
Kunezinhlobo ezimbili ze-HDMI "ezingenantambo" ezinomncintiswano, ngamunye osekela iqembu lawo lemikhiqizo: WHDI ne-Wireless HD (WiHD).
Zombili lezi zikhetho zenzelwe ukwenza kube lula kakhulu ukuxhuma imithombo ye-HDMI kanye nokubukwa ngaphandle kwekhebula elingabonakali (ikakhulukazi uma i-TV yakho noma iphrojekti yevidiyo ingena egumbini).
Kodwa-ke, njengoba nje nokuxhumeka kwe-HDMI wendabuko, kungaba khona "ama-quirks" njengokungathi ibanga, izinkinga zomzila, kanye nokuphazamiseka okutholakala eduze nomzila ongenazintambo noma idivayisi efanayo (kuye ngokuthi usebenzisa i-WHDI noma i-WiHD).
Futhi, kukhona umehluko wokuthi izindlela zombili zombili zingase zisetshenziswe kanjani ngezinga lemikhiqizo kanye neyomodeli, njengokuthi ezinye izakhiwo ezizungezile zomsindo kanye ne-3D zingahle zigcinwe, futhi, eziningi zokudlulisa / ukumukelika "i-HDMI" ezingenalo i-4K zihambisana, kodwa, ukuqala ngo-2015, i-4K isetshenziswe kumayunithi akhethiwe. Uma udinga ukuhambisana okungu-4K, nakanjani hlola izici zomkhiqizo nama-specs ukuze uqiniseke ukuthi unikeziwe.
Izibonelo zezingcingo zokuxhumeka kwe-HDMI ezingenantambo zifaka:
I-Actiontec MWTV2KIT01 yami engenantambo
IOGEAR I-5x2 ye-HDMI ye-Matrix PRO Switcher engenantambo
Nyrius WS54
Okubalulekile
Njengawo noma cha i-HDMI yizinga eliyinhloko lokuxhumeka kwezinto ezisetshenziselwa yaseshashalazini yasendlini, futhi aluhambi noma nini nanini.
Ehlangothini elihle lezinto, i-HDMI inikeza ikhono lokudlulisa ividiyo ye-HD (futhi manje engu-4K), kanye namafomethi alalelwayo adingekayo avela kumakhi womthombo kuya kumamukeli wekhamera nemiboniso yevidiyo. Ngisho nezwe le-PC lifikile ebhodini lokuxhumana ne-HDMI manje isici esimisiwe kuma-desktops nama-laptops.
Kodwa-ke, naphezu kokwamukelwa kwayo, i-HDMI ayizinkinga futhi enye yobuthakathaka bayo ukungakwazi ukudlulisela izimpawu zevidiyo emadolobheni amade ngaphandle kokusekelwa okwengeziwe.
Izinketho ezisuselwe kuzintambo zizinzile kakhulu, kungakhathaliseki ukuthi zisebenzisa i-HDMI ngokuhambisana ne-Ethernet, iFiber noma i-Coax. Noma kunjalo, ama-wireless anganeliseka ngaphansi kwezimo ezithile.
Uma usungula uhlelo lwezemidlalo yaseshashalazini lapho kukhona ibanga elide phakathi kwezingxenye zakho ze-HDMI ezixhumekile, futhi uthola ukuthi azisebenzi nje, nakanjani ucabangele izinketho ezixoxwe ngazo ngenhla njengezixazululo ezingenzeka.
