Huawei adayambitsa ukadaulo watsopano wa HWA Bluetooth HD audio transmission protocol, Yokhala Ndi Phokoso Labwinoko Kuposa LDAC
mainstream Bluetooth nyimbo kufala codec
Okonda nyimbo omwe amakonda kumvera nyimbo komanso kukhala ndi zofunika kwambiri pamawu omveka, ayenera kudziwa kuti ma codec apano a Bluetooth otumizira nyimbo ali ndi SBC, Qualcomm's aptX/ aptX HD, Apple's AAC ndi Sony's LDAC.
SBC ndiyomwe imathandizidwa kwambiri; Apple AAC ndi kudzikonda kusasinthasintha mgwirizano, iTunes sitolo nyimbo ndi iOS Bluetooth kufala mtundu ndi za 320kbps code mlingo (iPhone / iPad kokha anathandiza AAC & SBC); Qualcomm aptX ili ndi ma code apamwamba kwambiri (imafuna aptX HD) ndipo imatha kufikira 576kbps. Komabe, ma codec apamwamba kwambiri a codec pamwambapa sangathe kufika pamlingo wocheperako wofunikira wa 44.1 kHz/16 bit lossless compression (mwachitsanzo, mawonekedwe a FLAC ndi pafupifupi 700 kbps). Sony LDAC ikhoza kuonjezera mlingo wa biti kufika pa 909kbps (zogwirizana ndi 44.1kHz kapena 88.2kHz mlingo wa zitsanzo) kapena 990kbps (zogwirizana ndi 48kHz kapena 96kHz mlingo wa zitsanzo). Mwachidziwitso, ndizotheka kufalitsa ma audio pafupifupi osatayika kudzera pa intaneti ya Bluetooth, yomwe ikufanana ndi mtundu wamtundu wa CD. Chifukwa chake, mtundu wamawu wotumiza ndi Bluetooth kuchokera pamwamba mpaka pansi ndi: LDAC> aptX> AAC> SBC.
Kodi HWA bluetooth transmission protocol ndi chiyani
HWA dzina lonse ndi Hi-Res Wireless Audio. Mulingo wokwanira wotengera kumvetsera kwa ogula sikuti umangokhudza zofunikira pakuchita monga ma codec, kutumiza opanda zingwe, kuchedwa, kusokoneza, Kuwongolera phokoso, kutulutsa mowonekera, komanso kupirira, komanso kumaganiziranso zowunikira zama electroacoustic komanso mtundu wamawu omvera, osati Bluetooth Audio codec.Mulingo womveka bwino wopanda zingwe wopangidwa molumikizana ndi Huawei, China Audio Association, ndi China Electronics Technology Standardization Research Institute, mogwirizana ndi mabizinesi 30 apakhomo ndi akunja. Ndiwonso muyeso woyamba wopangidwa ndi opanga kunyumba kuti apititse patsogolo magwiridwe antchito amtundu wa Bluetooth. Zimatengera LDHC codec, yomwe ili bwinoko pang'ono kuposa Qualcomm aptxHD ndi Sony LDAC. Atatuwo anali amtundu wamtundu wamawu, koma mtundu wamawu udali wabwinoko pambuyo pa kusintha kwa Huawei.
mwayi waukadaulo wa HWA
Ubwino waukulu waukadaulo wa HWA ndikuti sikuti umangotsimikizira kusamvana kopitilira muyeso wamawu opanda zingwe, kumatsimikizira kuyera kwamtundu wamawu, komanso kumasunga mtunda wokhazikika wogwiritsidwa ntchito komanso chidziwitso pansi pamiyezo yapamwamba yamawu. M'mbuyomu, mahedifoni opanda zingwe sakanatsimikizira mtundu wa mawu. Zidzakhala zinthu zakale. Komanso, monga wochedwa, HWA ndi chilolezo chaulere; izi zathandizanso kwambiri opanga zoweta kupanga chojambula chachikulu tsogolo opanda zingwe phokoso khalidwe la mafoni.
Chifukwa cha Huawei popereka ukadaulo waulere uwu, opanga ma Bluetooth achepetsa mtengo wa ma patent, ndikupereka ma module abwinoko a Bluetooth kumakampani opanga ma Bluetooth, opatsa ogula nyimbo zabwino kwambiri. M'tsogolomu, Feasycom idzapulumutsa ndalama kwa makasitomala pamene ikupereka ma modules abwino a Bluetooth kwa makasitomala, pogwiritsa ntchito luso la HWA.
