UHuawei wethule ubuchwepheshe obusha be-HWA Bluetooth HD transmission protocol, enekhwalithi yomsindo engcono kune-LDAC
i-codec evamile yokudlulisa umculo ye-Bluetooth
Abathandi bomculo abathanda ukulalela umculo futhi abanezidingo eziphezulu zekhwalithi yomsindo, kufanele bazi ukuthi i-codec evamile yamanje yokudlulisa umculo ye-Bluetooth ine-SBC, i-Qualcomm's aptX/ aptX HD, i-Apple's AAC ne-LDAC yakwaSony.
I-SBC iyona esekelwa kabanzi; I-Apple AAC iyisivumelwano esizishintshayo, umculo wesitolo se-iTunes kanye nefomethi yokudlulisela ye-Bluetooth ye-iOS cishe izinga lekhodi elingu-320kbps (i-iPhone/iPad isekele i-AAC ne-SBC kuphela); I-Qualcomm aptX inenani eliphakeme kakhulu lekhodi (idinga i-aptX HD) futhi ingafinyelela ku-576kbps. Nokho, izinga eliphezulu kakhulu lekhodi lekhodekhi engenhla alikwazi ukufinyelela imfuneko yesilinganiso sebhithi esincane esingu-44.1 kHz/16 bit yokucindezelwa okungalahleki (isibonelo, ifomethi ye-FLAC icishe ibe ngu-700 kbps). I-Sony LDAC ingakhuphula izinga lebhithi libe ngu-909kbps (elihambisana nesilinganiso samasampula esingu-44.1kHz noma esingu-88.2kHz) noma esingu-990kbps (okuhambisana nesilinganiso esingu-48kHz noma esingu-96kHz). Ngokombono, kungenzeka ukudlulisa umsindo ocishe ungalahleki ngoxhumo lwe-Bluetooth, oluqhathaniseka nekhwalithi yomsindo wekhwalithi ye-CD. Ngakho-ke, ikhwalithi yomsindo yokudlulisa nge-Bluetooth ukusuka phezulu ukuya phansi ithi: LDAC> aptX> AAC> SBC.
Iyini i-HWA bluetooth transmission protocol
Igama eligcwele le-HWA i-Hi-Res Wireless Audio. Izinga eliphelele elisuselwe kokuhlangenwe nakho kokulalela kwabathengi alihlanganisi nje kuphela izidingo zokusebenza ezifana ne-codec, ukuhanjiswa okungenantambo, ukubambezeleka, ukulwa nokuphazamiseka, Ukulawulwa komsindo okusebenzayo, ukudluliswa okusobala, nokubekezela, kodwa futhi icabangela izinkomba ze-electroacoustic ezihlosiwe kanye nekhwalithi yomsindo ozimele, hhayi i-codec ye-Bluetooth Audio.Izinga lokulalelwayo lokuchazwa okuphezulu kwe-wireless elithuthukiswe ngokuhlanganyela yi-Huawei, i-China Audio Association, kanye ne-China Electronics Technology Standardization Research Institute, ngokubambisana namabhizinisi angu-30 asekhaya nawangaphandle. Futhi iyindinganiso yokuqala eyenziwe abakhiqizi basekhaya ukuthuthukisa ukusebenza kwekhwalithi yomsindo we-Bluetooth. Isekelwe kukhodekhi ye-LDHC, engcono kancane kune-Qualcomm aptxHD ne-Sony LDAC. Laba bobathathu ekuqaleni bekungabezinga lekhwalithi yomsindo, kodwa ikhwalithi yomsindo yayingcono ngemva kokulungiswa kukaHuawei.
inzuzo yobuchwepheshe be-HWA
Inzuzo enkulu yobuchwepheshe be-HWA ukuthi ayiqinisekisi kuphela ukulungiswa okuphezulu kokudluliswa komsindo okungenantambo, iqinisekisa ukuhlanzeka okuphezulu kwekhwalithi yomsindo, kodwa futhi igcina ibanga elizinzile lokusebenzisa okuvamile kanye nolwazi ngaphansi kwamazinga aphezulu ekhwalithi yomsindo. Ngaphambilini, ama-headphone angenantambo awakwazanga ukuqinisekisa ikhwalithi yomsindo. Kuzoba yinto yesikhathi esidlule. Ngaphezu kwalokho, njengomuntu ofike sekwephuzile, i-HWA iyilayisensi yamahhala; lokhu futhi kubasize kakhulu abakhiqizi basekhaya ukuthi benze intuthuko enkulu esikhathini esizayo ikhwalithi yomsindo engenazintambo yamaselula.
Ngenxa ye-Huawei ngokunikeza lobu buchwepheshe bamahhala, abakhiqizi be-Bluetooth bazonciphisa izindleko zamalungelo obunikazi, futhi banikeze amamojula omsindo we-Bluetooth angcono ezinkampanini zemikhiqizo ye-Bluetooth, banikeze abathengi umculo wekhwalithi engcono. Ngokuzayo, i-Feasycom izokonga izindleko kumakhasimende kuyilapho inikeza amamojula e-Bluetooth angcono kumakhasimende, isebenzisa ubuchwepheshe be-HWA.
