Masiqale ukuthetha nge-HDMI, isifinyezo esiqhelene naso namhlanje, ikakhulu kuba sisinxibelelaniso esiqhelekileyo sevidiyo yedijithali kunye nesandi esinomgangatho ongcono. Kodwa iseyenye intambo ekuya kufuneka sijongane nayo, nokuba kukuzama ukuyifihla okanye ukufikelela kwindawo esiya kuyo. Kodwa… Kutheni uqhubeka usebenzisa iintambo xa ibluetooth okanye iWiFi ngoku zikumgangatho kulo naliphi na ikhaya? Kumgangatho oxabisekileyo, ungaphezulu kwayo nayiphi na enye indlela yokuhambisa ividiyo.
Kodwa ayisiyiyo yonke into elahlekileyo, kwiminyaka embalwa bekukho enye indlela, i I-HDMI engenazingcingo, into ekhoyo kodwa akukho mntu uyaziyo, Ukudibanisa umgangatho osinika wona kunye nentuthuzelo yokungasebenzisi ikhebula ukuqhagamshela iliso lethu okanye umabonwakude nezixhobo zekhompyutha. Kuba eyona ngxaki inkulu xa uqhagamshela okanye unqamla ikhonkco lethu okanye ikhompyuter kumabonwakude ijongana nolo tangle lweentambo ezibonakala zingenasiphelo, ngakumbi xa umgama phakathi kwezi zimbini ukhulu kakhulu. Hlala ukuze ufunde ngakumbi ngale teknoloji kwaye kutheni ingathandwa.
I-HDMI engenazingcingo, engaziwayo
Kukho izixhobo ezahlukeneyo ezixhasa i-HDMI engenazingcingo, Ngokungafaniyo nezinye iindlela ezinje nge-AirPlay okanye iChromecast, le ayifuni uxhumano lweWiFi ukuze isebenzeKe ngoko, asixhomekekanga kukugubungela umzila okanye ukusondela kwendlela ukuze ufumane umgangatho ophucukileyo. Umthumeli usebenzisa ibhendi ye-5 GHz (ngokungaphantsi kakhulu kune-2,4 GHz) umgama wolwamkelo uphakathi kwe-10 ukuya kwi-30 yeemitha, ke uluhlu lubanzi kakhulu.
Kuya kufuneka siyiqonde into yokuba iindonga ezinokubakho phakathi komamkeli kunye nommisi kufuneka zongezwe kulo mgama, kuba ezi ziya kunciphisa uluhlu kakhulu. Kule minyaka, bezininzi abavelisi abasungule iimveliso ezisebenzisa i-HDMI engenazingcingo esebenza kwi-60 kunye ne-190GHz, ngokwamaqela angenaphepha mvume elithile.
Ayizizo zonke izibonelelo nge-HDMI engenazingcingo
Eyona nto ibaluleke kakhulu kule teknoloji ngaphandle kwamathandabuzo lixabiso. Nangona ayisiyiyo kuphela, kuba isiginali yedijithali edlula kwi-HDMI kufuneka ibhalwe ngekhowudi, idluliselwe, ifunyanwe kwaye ikhishwe ikhowudi. Kwenzeka ntoni ngendlela engenazingcingo kulibaziseko oloyikisayo okanye kwi-latency phakathi kokukhupha nokwamkela. Le yinto esingazukuyibona kwinqanaba elikhulu xa sibukele iimovie okanye uthotho, kodwa iya kuba yinto enomsindo kwaye ayinyamezeleki xa idlala imidlalo yevidiyo.
Kukho iinketho ezithembisa i-lag ye-0, kodwa oku kuya kwenzeka kuphela ukuba umgama phakathi kwe-emitter kunye nomamkeli mfutshane kakhulu, hayi ngaphezulu kwe-5 yeemitha kwaye okoko nje kungekho ngxaki ziphazamisayo nezinye izixhobo ezingenazingcingo. Kule nto ayichaphazeli kuphela izixhobo esinazo ekhaya, kodwa nazo ezo banokuba nazo abamelwane bethu. Ingcebiso yam iya kuba kukuthenga olu hlobo lwezinto kwiivenkile apho zamkela khona imbuyekezo, ezinje ngeAmazon.
Umtsalane kodwa umile, ngoba?
Obu buchwephesha bubonakala bunengqiqo kodwa abugqibi ukuthatha, esona sizathu sibalulekileyo kukuba ukunqongophala kwesivumelwano phakathi kwabavelisi ukwenza umgangatho. Ukuthengisa okuncinci kolu hlobo lonxibelelwano kube negalelo koku, ngenxa yoko abakhuthazwa ukuba batyale imali.
Ngaba le nkqubo iyimfuneko kwaye iluncedo, okanye ukusikwa kweentambo ngokulula?
Kusetyenziso lwasekhaya, ayikhuthazwa imeko eqhelekileyo, apho izixhobo zihlala zisondele kumabonwakude okanye ekubekweni esweni, ke kuyacetyiswa ukuba kusetyenziswe intambo ye-HDMI elungileyo, kuba nentambo intsebenzo inokuba mbi, ukuba umgangatho ayonelanga. Kwimeko ezithile kuphela njengokusebenzisa idikhowuda yevidiyo enye kumagumbi amaninzi, apho ukusebenzisa i-HDMI engenazingcingo kuya kwenza ingqiqo enkulu.
Nangona kunjalo, kucetyiswa ngakumbi ukuba kwenziwe ukufakelwa kweentambo ngokufihlakeleyo ngeeRegattas okanye iigatha, kuba umgangatho wokugqibela womfanekiso uya kuba phezulu kakhulu, kwaye nexabiso lale teknoloji lisephezulu. Zininzi iindlela zokwenza ufakelo olucocekileyo ngentambo efihliweyo.
Ngaphandle kwezi ngxaki, yinto eya kuthi ekugqibeleni ifike, ukuba ayenziwanga nge-HDMI engenazingcingo iya kuba nolunye uhlobo lonxibelelwano, kodwa iintambo zolu hlobo losasazo ziya kubakho ngokupheleleyo kungekudala okanye kamva. NjengeWiFi okanye ibluetooth, umgangatho othatha indawo yoqhagamshelo lwe-HDMI unokukhawuleza uphume. Ukushiya oku wedwa kwaye kuphela iimeko ezithile ezinjengemidlalo yevidiyo.
Olunye uhlobo kwintengiso
Ukuba sijonga into efanayo kwintengiso, sifumana WHDI. Isebenza usebenzisa ibhendi ye-5 GHz kwaye inokufikelela kwisisombululo seepikseli ze-1920 x 1080. Ke isisombululo se-4K siya kugwetywa ngaphandle ngale nkqubo. Ukongeza, ihlala inika iingxaki ezininzi kwiirouters ezintsha ezisebenzisa ibhendi ye-5 GHz ukubonelela nge-WiFi Ac yesantya esiphezulu.
Kukho ezinye izisombululo ezinje I-WiGig inokusebenza kwizisombululo 4K okanye I-WirelessHD oko kungoyisa ukusikelwa umda okuxoxwe ngasentla. Kodwa iimveliso ezisebenzisa obu buchwephesha ziphantse azikho kwaye ezimbalwa esinokuzifumana zinendleko eziphezulu.
I-HDMI yemveli iyaqhubeka nokuvela kodwa inokhuphiswano olunzima
Ngelixa i-HDMI engenazingcingo ime endaweni yokuba ibe yintsalela, intambo yesiko ayiyeki ukuvela, inikezela ngcono kunye nokuhlaziya amaxabiso kunye nezigqibo eziphakamileyo, ngoku sifumana HDMI 2.1 njengeyona iphambili kunayo yonke, kangangokuba iithelevishini azihambelani.
Umntu okhuphisana naye onzima ufikile kwaye akukho mntu ndimaziyo ngaphandle kwakhe USB C, umgangatho okwazi ukwenza izinto ezininzi, kubandakanya ukutshaja izixhobo zethu, ukudlulisa idatha, ividiyo okanye isandi. Okwangoku iyasetyenziswa, ngakumbi ukubiza ii-smartphones zethu nge-Android, kodwa iApple iyifakile njengomgangatho kuzo zonke iikhompyuter zayo, ifikelela kunxibelelwano lwayo Iindudumo 3 40GBps / s kunye nomthwalo wamandla ukuya kwi-100w.
Nangona imeko itsalela apha, ngenxa yokulula konxibelelwano lwayo kunye nokukhanya kwentambo, ayisiyiyo eyona ikhuthazwayo ekudlaleni, kuba Imigangatho ye-USB-C ayisayi kuxhasa iAdaptive-Sync de imowudi ye-DP Alt inyuselwe kuhlobo lwe-1.4, ke ngekhe ukwazi ukusebenzisa iFreeSync okanye iG-Sync.
