Ake siqale ukukhuluma nge-HDMI, isifinyezo sonke esizijwayele namuhla, ngokuyisisekelo ngoba ukuxhumana okujwayelekile kwevidiyo yedijithali nomsindo onekhwalithi engcono. Kepha kusengenye yezintambo okuzofanele sibhekane nazo, noma ukuzama ukuyifihla noma ukufinyelela lapho iya khona. Kepha… Kungani uqhubeka usebenzisa izintambo lapho i-bluetooth noma i-WiFi manje seyijwayelekile kunoma yiliphi ikhaya? Ngekhwalithi eliyigcinayo, iphakeme kakhulu kunanoma iyiphi enye indlela yokudlulisa ividiyo.
Kepha akusikho konke okulahlekile, ngoba eminyakeni embalwa kube nokunye, i I-HDMI engenantambo, into ekhona kepha cishe akekho owaziyo, ukuhlanganisa ikhwalithi elisinikeza yona nenduduzo yokungasebenzisi ikhebula ukuxhuma isilawuli sethu noma ithelevishini ne-hardware. Njengoba inkinga enkulu lapho sixhuma noma sinqamula ikhonsoli yethu noma ikhompyutha kuthelevishini isebenza ngaleyo ntambo yezintambo ebonakala ingapheli, ikakhulukazi lapho ibanga phakathi kwalaba bobabili likhulu kakhulu. Hlala wazi kabanzi ngalobu buchwepheshe nokuthi kungani bungathandwa.
I-HDMI engenantambo, enkulu engaziwa
Kunezinhlobonhlobo zamadivayisi asekela i-HDMI engenantambo, Ngokungafani nezinye izinketho ezifana ne-AirPlay noma i-Chromecast, lena ayidingi ukuxhumana kwe-WiFi ukuze isebenzeNgakho-ke, asixhomekile ekusetshenzisweni komzila noma ukusondela kwawo ukuthola ikhwalithi ehloniphekile. Isidlulisi sisebenzisa ibhendi ye-5 GHz (egcwele kakhulu kune-2,4 GHz ejwayelekile) ibanga lokwamukela liphakathi kwamamitha ayi-10 nengama-30, ngakho-ke ububanzi bubanzi impela.
Kumele sikhumbule ukuthi izindonga ezingahle zibe khona phakathi komamukeli nophumile kufanele zengezwe kuleli banga, ngoba lezi zinganciphisa ububanzi kakhulu. Eminyakeni edlule, bebelokhu bebaningi abakhiqizi abethule imikhiqizo esebenzisa i-HDMI engenantambo esebenza ku-60 no-190GHz, ngamabhendi angenayo ilayisense ethile.
Akuzona zonke izinzuzo ezine-HDMI engenantambo
Ububi obubaluleke kakhulu balobu buchwepheshe ngaphandle kwentambo yintengo. Yize kungeyona yodwa, ngoba isignali yedijithali edlula kwi-HDMI kufanele ifakwe ikhodi, idluliswe, yamukelwe futhi ikhishwe ikhodi. Kwenzekani ngendlela engenantambo ukulibaziseka okwesabekayo noma ukubambezeleka phakathi kokuphuma nokwamukela. Lokhu kuyinto esingeke siyibone ngezinga elikhulu lapho sibuka ama-movie noma uchungechunge, kepha kuyinto ezocasula futhi ibuye akubekezeleleki lapho udlala imidlalo yevidiyo.
Kunezinketho ezithembisa i-0 imput lag, kepha lokhu kungenzeka kuphela uma ibanga phakathi kwe-emitter kanye nomamukeli lifushane kakhulu, hhayi ngaphezu kwamamitha ayi-5 futhi inqobo nje uma kungekho zinkinga zokuphazamiseka namanye amadivayisi angenantambo. Kulokhu azithinti kuphela amadivayisi esinawo ekhaya, kepha futhi nalawo omakhelwane bethu abangaba nawo. Isincomo sami kungaba ukuthenga lolu hlobo lwento ezitolo lapho bemukela khona ukubuya, okufana ne-Amazon.
Uyakhanga kepha umile, ngani?
Lobu buchwepheshe bubukeka bunengqondo kunazo zonke kepha abuqedi ukuqala, isizathu esibaluleke kunazo zonke ukuthi ukuntuleka kwesivumelwano phakathi kwabakhiqizi ukwakha indinganiso. Ukuthengiswa okuphansi kwalolu hlobo lokuxhumana kube nomthelela kulokhu, ngakho-ke abakhuthazwa ukuthi batshale imali.
Ingabe lolu hlelo luyadingeka ngempela futhi luyasebenziseka, noma ukusikwa kwentambo okulula?
Ekusebenziseni kwasekhaya, akunconywa ezimweni ezijwayelekile, lapho imishini ivame ukusondela kuthelevishini noma ukuqapha, ngakho-ke kungakuhle ukusebenzisa ikhebula elihle le-HDMI, ngoba ngisho nentambo ukusebenza kungaba kubi, uma ikhwalithi akwanele. Ezimweni ezithile kuphela njengokusebenzisa i-decoder yevidiyo eyodwa yamakamelo amaningi, lapho ukusebenzisa i-HDMI engenantambo kungenza umqondo omkhulu.
Noma kunjalo, kunconywa kakhulu ukwenza ukufakwa kwentambo okuqondayo ngama-regattas noma ama-gutters, ngoba ikhwalithi yokugcina yesithombe izoba phezulu kakhulu, futhi intengo yalobu buchwepheshe isephezulu. Kunezindlela eziningi zokwenza ukufakwa okuhlanzekile ngezintambo ezifihlwe kakhulu.
Noma kunalezi zingqinamba, kuyinto ezogcina ifikile, uma kungeyona nge-HDMI engenantambo kuzoba nolunye uhlobo lokuxhuma, kepha izintambo zalolu hlobo lokudlulisela zizozinikezwa ngokuphelele kungekudala. Njenge-WiFi noma i-bluetooth, indinganiso ethatha isikhundla soxhumano lwe-HDMI ingaphuma maduze. Ukushiya lokhu kuphela futhi kumacala athile afana nemidlalo yevidiyo.
Ezinye izindlela emakethe
Uma sibheka into efanayo emakethe, sithola ifayela le- WHDI. Isebenza ngokusebenzisa ibhendi ye-5 GHz futhi ingafinyelela ukulungiswa kwamaphikseli we-1920 x 1080. Ngakho-ke isinqumo se-4K sizokhishwa ngokuphelele ngalolu hlelo. Ngaphezu kwalokho, ijwayele ukunika izinkinga eziningi ngama-routers amasha asebenzisa ibhendi ye-5 GHz ukuhlinzekwa nge-WiFi Ac esheshayo.
Kukhona ezinye izixazululo ezinjenge I-WiGig lokho kungasebenza ezinqumweni 4K noma i I-WirelessHD lokho kuzonqoba ukulinganiselwa okukhulunywe ngenhla. Kepha imikhiqizo esebenzisa lobu buchwepheshe cishe ayikho futhi okumbalwa esingakuthola kunezindleko ezinkulu.
I-HDMI yendabuko ayiyeki ukuvela kodwa inembangi enzima
Ngenkathi i-HDMI engenantambo imile kwaze kwaba seqophelweni lokuba yizinsalela ezithile, ikhebula lendabuko aliyeki ukuthuthuka, linikeza amanani angcono futhi angcono wokuvuselela kanye nezinqumo ezikhula ngokwengeziwe, njengamanje sithola I-HDMI i-2.1 njengokuthuthukile kunakho konke, kangangoba amathelevishini awahambelani.
Umncintiswano onzima ufikile futhi angazi omunye ngaphandle kwakhe I-USB C, indinganiso ekwaziyo ukwenza izinto eziningi, kufaka phakathi ukushaja amadivayisi wethu, ukudlulisa idatha, ividiyo noma umsindo. Okwamanje iyasetshenziswa, ikakhulukazi ukukhokhisa ama-smartphones ethu nge-Android, kepha i-Apple iyifakile njengejwayelekile kuwo wonke amakhompyutha ayo, ifinyelela ngokuxhuma kwayo I-Thunderbolt 3 40GBps / s namandla omthwalo afinyelela ku-100w.
Yize ukuthambekela kudonsela lapha, ngenxa yobulula bokuxhumeka kwayo nokukhanya kwekhebula, namanje akusona isincomo sokudlala, ngoba Amazinga e-USB-C ngeke asasekela i-Adaptive-Sync kuze imodi ye-DP Alt ithuthukiselwe kunguqulo engu-1.4, ngakho-ke ngeke ukwazi ukusebenzisa i-FreeSync noma i-G-Sync.
