Cishe uke wabhekana nalokhu: lapho uhlela indawo yakho yokuzijabulisa egumbini lokuphumula, uke wabhekana nochungechunge lwezintambo nama-acronym abukeka sengathi abhalwe ngesiShayina. I-HDMI yafika esikhathini esithile esidlule ukuze isindise izimpilo zethu, isuse lezo zixhumi ezindala ze-analog kanye ne-DVI enzima, yaba indinganiso ephelele yokudlulisa isithombe nomsindo ngentambo eyodwa. Kodwa-ke, ubuchwepheshe abumi ndawonye, ​​​​futhi kuye kwavela izici ezengeziwe, nakuba zizwakala ziyinkimbinkimbi, zenzelwe ukwenza izimpilo zethu zibe lula kakhulu.
Ngaphakathi kwalolu hlelo lokusebenza, ubuchwepheshe obubili buvame ukudala ukudideka okukhulu: i-ARC kanye nomfowabo othuthuke kakhulu, i-eARC. Empeleni, sikhuluma ngamakhono okuxhumana aqondiswe kabili avumela amadivayisi akho ukuthi angagcini nje ngokuthola idatha kodwa futhi axhumane. Uma ufuna ukuyeka ukuhlushwa yizilawuli ezikude futhi uthole umsindo we-cinematic kusuka ku-Smart TV yakho, ukuqonda le mibono kubalulekile ukuze ugweme ukuchitha imali ezintanjeni ezingadingekile noma ekusethweni okungasebenzi kahle.
Ukuqonda i-HDMI ARC: Indlela yokubuya komsindo
Ukuze uqale ngezinto eziyisisekelo, i-HDMI imele i-High-Definition Multimedia Interface, futhi yilokho esikusebenzisayo ukuthwala ividiyo nomsindo kusuka ku-console noma ebhokisini le-set-top kuya esikrinini. Kodwa-ke, i-ARC (Audio Return Channel) , eyethulwe kunguqulo 1.4, ishintsha umdlalo. Esikhundleni solwazi olugeleza ohlangothini olulodwa kuphela, ivumela i-TV ukuthi ithumele umsindo emuva ku-AV receiver noma ku-soundbar.
Lokhu kuyimpumuzo yangempela ngoba, ngaphambi kokuba kube khona i-ARC, uma ufuna umsindo ovela kuhlelo lokusebenza lwe-Netflix olufakwe ku-TV yakho ukuthi udlale ngezipikha zakho zangaphandle, kwakudingeka wengeze ikhebula le-fiber optic elengeziwe (i-Toslink) . Nge-ARC, lelo khebula liyanyamalala, njengoba isixhumanisi esifanayo se-HDMI esithwala isignali yevidiyo singaphatha umsindo ngokuphambene, okuholela ekufakweni okuhlanzekile kakhulu ngezintambo ezingaxabene kakhulu ngemuva kwefenisha.
Isebenza kanjani ngobuchwepheshe futhi yiziphi izinzuzo ezinikezayo?
Ukuze lokhu kwenzeke, i-HDMI isebenzisa iziteshi ezimbili eziyinhloko. Eyokuqala yi-TMDS, enesibopho sokudlulisa idatha ngesivinini esikhulu ngenkathi inciphisa ukuphazamiseka, kanti enye yi-CEC (Consumer Electronics Control). Eyokugcina iyigugu eliyinhloko ukuze kube lula kumsebenzisi, njengoba ikuvumela ukulawula amadivayisi amaningi ngesilawuli kude esisodwa . Isibonelo, ungalungisa ivolumu yebha yakho yomsindo usebenzisa isilawuli kude se-TV ngaphandle kokushintsha njalo phakathi kwamadivayisi.
Ngokuphathelene nekhwalithi, i-ARC ingcono kakhulu kunokuxhumeka okudala kwe-optical. Ingaphatha amafomethi amaningi ajulile njenge-Dolby Digital ne-DTS, asetshenziswa yizinsizakalo eziningi zokusakaza. Kodwa-ke, yize kuyisisombululo esisebenzayo nesanele emindenini eminingi, inomkhawulo wezobuchwepheshe: ayikwazi ukuphatha amafomethi omsindo angacindezelwanga noma amazinga e-Blu-ray disc adinga kakhulu.
Ukugxumela ku-eARC: Amandla kanye nesisombululo esiphezulu
Yilapho i-eARC ingena khona, okuyisiteshi sokubuyisa umsindo esithuthukisiwe ( i-ARC ), esihlanganiswe ne-HDMI 2.1 standard. Uma i-ARC yayiwumgwaqo ogandayiwe, i-eARC iwumgwaqo ohamba ngesivinini esikhulu. Inzuzo yayo eyinhloko i -bandwidth yayo enkulu (efika ku-48 GB/s ku-HDMI 2.1), evumela umsindo wesinqumo esigcwele ukuthi udluliselwe ngaphandle kokucindezelwa kwesiginali.
Lokhu kubalulekile kubantu abathanda imisindo kanye nabathandi bemidlalo yaseshashalazini yasekhaya, njengoba i-eARC isekela amafomethi aphezulu njenge- Dolby Atmos kanye ne-DTS:X engenakulahlekelwa . Ngenkathi i-ARC ingakwazi ukuphatha kuphela inguqulo ecindezelwe ye-Atmos (njenge-Netflix's), i-eARC ikuvumela ukuthi ujabulele ikhwalithi eluhlaza yediski ye-4K Blu-ray. Ngaphezu kwalokho, ifaka ukulungiswa kokuvumelanisa okuphoqelekile , isusa leyo nkinga yokuvumelanisa izindebe lapho ukunyakaza kwezindebe kungafani nomsindo.
Ukuqhathanisa okuqondile: i-ARC vs i-eARC
- Ububanzi: I-ARC inqunyelwe (cishe i-1 Mbps), kuyilapho i-eARC ikhulisa umthamo wayo cishe ifike ku-37 Mbps.
- Ikhwalithi yomsindo: I-ARC ihlala kunguqulo ecindezelwe engu-5.1, kuyilapho i-eARC ivumela umsindo we-7.1 ongacindezelwanga kanye namafomethi anesinqumo esiphezulu.
- Ukuhambisana: I-ARC yazalwa ngo-2009 ine-HDMI 1.4; i-eARC yafika ngo-2017 inenguqulo 2.1.
- Ukuvumelanisa: Ku-ARC, ukulungiswa kwezindebe kuyinto yokuzikhethela; ku-eARC, kuyimpoqo. isici esiyimpoqo.
Amathiphu awusizo okufaka kanye nezintambo
Uma ufuna lokhu kusebenze, into yokuqala okufanele uyenze ukubheka ngemuva kwe-TV yakho. Akuwona wonke ama-port e-HDMI afanayo; udinga ukubheka lawo abhalwe ukuthi i-HDMI (ARC) noma i-(eARC) . Uma uxhuma i-soundbar kunoma iyiphi i-port, isiteshi esibuyayo ngeke sisebenze, futhi umsindo uzokhawulelwa ezipikheni zangaphakathi ze-TV.
Kunokudideka okukhulu mayelana nezintambo. Nge-ARC eyisisekelo, cishe noma iyiphi ikhebula le-HDMI lesimanje lizosebenza. Kodwa ukuze uthole okuningi ku-eARC kanye namafomethi anesinqumo esiphezulu, kunconywa kakhulu ukusebenzisa ikhebula lesivinini esiphezulu eliqinisekisiwe . Lokhu kuvimbela ukuphuma komsindo ngezikhathi ezithile futhi kuqinisekisa ukugeleza kwesignali yedatha okubushelelezi. Futhi, khumbula ukuya kumenyu yezilungiselelo ze-Smart TV yakho ukuze unike amandla ukuphuma komsindo kwe-CEC kanye ne-ARC/eARC, njengoba lokhu ngezinye izikhathi kukhutshazwa ngokuzenzakalelayo.
Ukuba nesistimu ehlanganisa i-HDMI 2.1 kanye ne-eARC kuqinisekisa ukuthi noma yimuphi umthombo oxhunywe ku-TV, kungaba yi-console yesizukulwane esilandelayo noma uhlelo lokusebenza lokusakaza, uthumela umsindo ongcono kakhulu ohlelweni lwakho lomsindo. Ekugcineni, kumayelana nokwenza lula ukuxhumana ngokuqeda izintambo ezingadingekile nokuqinisekisa ukuthi ulwazi lomsindo luhambisana nekhwalithi yesithombe samanje, kufezwe ukucwiliswa okuphelele kokuqukethwe ngaphandle kwezinkinga zobuchwepheshe.
