Njengoba kungenzeka wazi, ikhwalithi yomsindo, ukubambezeleka kwamadivayisi ahlukene e-Bluetooth kungahluka kakhulu. Siyini isizathu? Namuhla sizokunikeza impendulo yalo mbuzo.
Ukudluliswa komsindo kwekhwalithi ephezulu ye-Bluetooth kusekelwe ikakhulukazi kuphrofayela ye-A2DP. I-A2DP imane ichaze umthetho olandelwayo kanye nenqubo yokudlulisa ulwazi lomsindo wekhwalithi ephezulu njenge-mono noma isitiriyo esiteshini esingaxhunywanga se-asynchronous. Le phrothokholi iyafana nepayipi lokudlulisa idatha yomsindo. Idatha edluliswa nge-Bluetooth ihlukaniswe ngezinhlobo ezilandelayo ngokuya ngefomethi yayo yombhalo wekhodi:
yini I-SBC
Lena ifomethi ejwayelekile yombhalo wekhodi yomsindo we-Bluetooth. Ifomethi yekhodi yephrothokholi ye-A2DP (Advanced Audio Distribution Profile) Isilinganiso esiphezulu esivumelekile ngu-320kbit / s ku-mono kanye no-512kbit / s eziteshini ezimbili. Wonke ama-chip e-Bluetooth azophinde asekele le fomethi yombhalo wekhodi womsindo.
yini I-AAC
Ubuchwepheshe obunikezwe i-Dolby Laboratories, i-algorithm yombhalo wekhodi wokucindezelwa okuphezulu. I-iPhone isebenzisa ifomethi ye-AAC yokudluliswa kwe-Bluetooth. Njengamanje, amadivaysi omsindo e-Apple e-Bluetooth asebenzisa ubuchwepheshe bokufaka ikhodi be-AAC. Futhi amadivaysi amaningi atholayo njengezipikha / ama-headphone e-Bluetooth emakethe nawo asekela ukukhishwa kwekhodi kwe-AAC.
yini I-APTX
Kuyi-algorithm yekhodi yelungelo lobunikazi ye-CSR. Ngemuva kokuthi itholwe ngabakwaQualcomm, yaba ubuchwepheshe bayo obuphambili bokubhala amakhodi. Emphakathini kuthiwa ingafinyelela izinga lomsindo we-CD. Iningi lamafoni e-Android amasha afakwe i-APTX. Lobu buchwepheshe bokubhala amakhodi bomsindo busebenza kahle kakhulu kunokubhala ngekhodi kwe-Bluetooth yakudala, futhi umuzwa wokulalela ungcono kunalokhu okubili kwangaphambilini. Amadivayisi asebenzisa ubuchwepheshe be-APTX adinga ukufaka isicelo sokugunyazwa kwa-Qualcomm futhi akhokhe izindleko zokugunyazwa, futhi adinga ukusekelwa yizo zombili iziphetho zokudlulisa nokwamukela.
yini I-APTX-HD
I-aptX HD iwumsindo onencazelo ephezulu, futhi ikhwalithi yomsindo icishe ifane ne-LDAC. Isekelwe ku-aptX yakudala, enezela iziteshi ukusekela ifomethi yomsindo engu-24 bit 48KHz. Izinzuzo zalokhu isilinganiso esiphansi sesignali-kuya-nomsindo kanye nokuhlanekezela okuncane. Ngesikhathi esifanayo, izinga lokudlulisela likhuphuke kakhulu.
yini I-APTX-LL
I-aptX LL iphansi-latency, isici esiyinhloko ukuthi ingakwazi ukuzuza ukubambezeleka okungaphansi kuka-40ms. Siyazi ukuthi umkhawulo wokubambezeleka abantu abangawuzwa ngu-70ms, futhi ukufinyelela ku-40ms kusho ukuthi asikwazi ukuzwa ukubambezeleka.
yini I-LDAC
Lobu ubuchwepheshe bokubhala amakhodi okulalelwayo obuthuthukiswe yi-SONY, obungadlulisela okuqukethwe komsindo wokucaca okuphezulu (Hi-Res). Lobu buchwepheshe bungadlulisa okuningi ngokuphindwe kathathu kunobunye ubuchwepheshe bokubhala amakhodi ngokubhala amakhodi okuphumelelayo kanye nokupakishwa okuncane okulungiselelwe Idatha. Okwamanje, lobu buchwepheshe busetshenziswa kuphela kumishini ye-SONY yokudlulisa nokwamukela. Ngakho-ke, isethi ye-SONY kuphela yezinto ezisetshenziswayo zokudlulisa nokwamukela ezisekela ubuchwepheshe bokubhala ikhodi bomsindo we-LDAC engathengwa ukuze kusekelwe ukudluliswa kwedatha yomsindo ye-Bluetooth enekhodi ye-LDAC.
I-Feasycom yethule izixazululo ezimbalwa zemojuli ezisekela amafomethi we-APTX. Ongabathola ngezansi:
Ucabangani ngalesi Sethulo samafomethi womsindo we-Bluetooth angu-6 Amakhulu? Zizwe ukhululekile ukuthumela umbuzo ukuze uthole imininingwane eyengeziwe. Ngiyabonga ngokufunda lesi sihloko.
