- I-HDMI ARC kanye ne-eARC zikuvumela ukuthi uthumele umsindo kusuka ku-TV uye kudivayisi yangaphandle usebenzisa ikhebula elilodwa.
- Inguqulo ye-eARC inikeza i-bandwidth ephezulu, evumela amafomethi omsindo angenakulahlekelwa njenge-Dolby Atmos.
- Iphrothokholi ye-CEC ihambisana nalezi zobuchwepheshe, ikuvumela ukuthi ulawule amadivayisi amaningi ngesilawuli kude esisodwa.
Sekuphele amashumi eminyaka ambalwa kusukela izinga le-HDMI lifikile ukuze liguqule indlela esidla ngayo okuqukethwe emakamelweni ethu okuhlala, sishiya lawo makhebula e-analog ayebonakala sengathi avela eNkathini Yamatshe. Empeleni, lesi sikhombimsebenzisi se-multimedia esichazayo kakhulu sinesibopho sokudlulisa ividiyo nomsindo wedijithali ongacindezelwanga, okuvumela ikhwalithi yesithombe esicacile nomsindo ojulile, konke ngesixhumi esisodwa.
Kodwa-ke, ngokuhamba kwesikhathi, i-HDMI ishintshe ukwenza izimpilo zethu zibe lula. Kuvele ubuchwepheshe obufana ne-ARC kanye ne-eARC, obuqeda isidingo sokuxinana kwezintambo ngemuva kwe-TV, okwenza kube lula ukuxhumana phakathi kwethelevishini nezinhlelo zomsindo zangaphandle njengezinsimbi zomsindo noma ama-AV receiver.
Ukuqonda umqondo we-HDMI
Ukuze ugweme ukudukiswa, kuyasiza ukwazi kahle ukuthi kusho ukuthini i-HDMI. Igama elithi High-Definition libhekisela ekhonweni lokuphatha inani elikhulu ledatha ukuze isithombe singashintshi futhi umsindo ucace bha. Ingxenye ye-Multimedia ikhombisa ukuthi ayithwali ividiyo kuphela kodwa futhi nomsindo weziteshi eziningi, kanti igama elithi Interface lichaza indawo ebonakalayo lapho amadivayisi amabili exhumana khona.
Ngokwemvelo, isixhumi esivame kakhulu uhlobo lwe-A olunamaphini ayi-19. Imininingwane ebalulekile ukuthi, yize izintambo zingase zibukeke zifana kakhulu, kunezinguqulo ze -High Speed kanye ne-Ultra High Speed . Lezi zokugcina zibalulekile uma ufuna ukuthola okuningi kuma -smart TV anamuhla ane-HDMI 2.1, njengoba esekela amazinga okudlulisa asheshayo kakhulu. Kodwa-ke, ungakhathazeki ngokuhambisana, njengoba ikhebula lesimanje lizosebenza kahle namadivayisi amadala , yize kungeke kuthuthukise ikhwalithi yesithombe se-TV endala.
Iyini ngempela i-HDMI ARC?
Isifinyezo esithi ARC simele i-Audio Return Channel . Kalula nje: I-HDMI ivame ukuthumela umsindo ovela emthonjeni (njenge-game console) ku-TV. Kodwa i-ARC ivumela umsindo oqondene nezinhlangothi ezimbili; okungukuthi, i-TV ingathumela umsindo ngaphandle , ikakhulukazi kubha yomsindo noma ku-amplifier.
Ngaphambi kokuba lokhu kube khona, uma ufuna ukulalela umsindo ovela kuhlelo lokusebenza lwe-Netflix olufakwe ku-TV yakho ngesistimu yakho yomsindo, udinga ikhebula elengeziwe le-optical. Nge-ARC, siyayisusa leyo khebula yesithathu ngoba ikhebula le-HDMI elifanayo elithwala isignali yevidiyo lingaphatha nesignali yomsindo. Kuyisisombululo esiwusizo kakhulu esivele sihambisana ne-HDMI version 1.4 kanye neyakamuva.
Ukufinyelela ku-HDMI eARC
Yilapho izinto ziba zimbi khona. I-eARC, noma i-Enhanced Audio Return Channel , inguqulo ethuthukisiwe eza ne-HDMI 2.1 standard. Uma i-ARC isivele iwusizo, i-eARC iyisilo ngokusebenza ngoba ine -bandwidth ephezulu kakhulu.
Inzuzo enkulu ukuthi i-eARC ivumela ukudluliswa komsindo onesinqumo esiphezulu ngaphandle kokucindezelwa. Ngenkathi i-ARC ihluleka ngamafomethi adinga umzamo omkhulu, i-eARC ingaphatha i-Dolby Atmos ne-DTS:X engenakulahlekelwa isebenzisa i-Dolby TrueHD codec. Ukuze ikusize ngokugcwele lokhu, kubalulekile ukuthi kokubili ithelevishini yakho kanye nohlelo lwakho lomsindo kusekele i-eARC nokuthi usebenzise ikhebula elishesha kakhulu ukuze ugweme ukuyeka noma ukwehluleka kwesignali.
Isengezo esiphelele: i-HDMI CEC
Njengoba sikhuluma ngezintambo ezihlakaniphile, asikwazi ukukhohlwa i-CEC (Consumer Electronics Control). Lesi sici sivumela amadivayisi ukuthi "akhulume" ukuze ukwazi ukulawula yonke into nge-remote eyodwa. Isibonelo, uma uvula isidlali se-Blu-ray, i-TV ivula ngokuzenzakalelayo bese ivula isiteshi esifanele.
Inkinga ukuthi uhlobo ngalunye luyinika igama elihlukile: i-Samsung iyibiza ngokuthi i-Anynet+, i-LG Simplelink, i-Sony BRAVIA Sync, kanye ne-Philips EasyLink. Nakuba ngokobuchwepheshe kufana, ukusetshenziswa ngezinye izikhathi kuyahlukahluka phakathi kwabakhiqizi futhi kungase kungasebenzi kahle ngaso sonke isikhathi, kodwa kusalokhu kuyindlela elula kakhulu yokugwema isiphithiphithi sokuba nama-remote amahlanu etafuleni.
Umhlahlandlela osheshayo wokuxhumana okulungile
Uma ufuna ukusetha uhlelo lwakho ngaphandle kwezinkinga, into yokuqala okufanele uyenze ukubheka ngemuva kwe-TV yakho imbobo ebhalwe ngqo i-HDMI ARC noma i-eARC , njengoba kungewona wonke amambobo e-HDMI analo leli khono. Xhuma leyo mbobo kubha yakho yomsindo kanye neminye imithombo yakho (ikhonsoli, ibhokisi lokusetha phezulu) kwamanye amambobo atholakalayo.
Uma ihadiwe isixhunyiwe, ungakhohlwa ukuya kuzilungiselelo ze-TV yakho ukuze usebenzise i-ARC/eARC kanye nokulawula kwe-CEC . Futhi, qiniseka ukuthi ukhetha imbobo ye-HDMI ehambisanayo njengokukhipha umsindo. Khumbula ukuthi uma uxhuma idivayisi ye-eARC kuleyo esekela i-ARC kuphela, ikhwalithi izonqunyelwa yisixhumanisi esibuthakathaka kakhulu ku-chain.
Ukuba nesistimu yomsindo elungiselelwe kahle kuncike ekukhetheni ubuchwepheshe obufanele okuqukethwe kwakho. Ngenkathi i-ARC yanele ukusetshenziswa kwansuku zonke, i-eARC iyindlela okufanele ilandelwe abathandi bemidlalo yaseshashalazini yasekhaya abafuna ukwethembeka okuphezulu komsindo. Ngokuhlanganisa ikhebula eliqinisekisiwe, amachweba ahambisanayo, kanye nokusebenza kwezinqubo zokulawula, uthola ulwazi olujulile ngezintambo ezimbalwa kakhulu ezingaba khona.
