Sezvaungave uchiziva, ruzha rwemhando, latency yeakasiyana maBluetooth madivayiri anogona kuve akasiyana zvakanyanya. Chikonzero chii? Nhasi tichakupa mhinduro kumubvunzo uyu.
Bluetooth yepamusoro-mhando yekufambisa yekufambisa inonyanya kuenderana neiyo A2DP mbiri. A2DP inongotsanangura iyo protocol uye maitiro ekufambisa emhando yepamusoro ruzivo rwemono kana stereo pane asynchronous yekubatanidza isina chiteshi. Iyi protocol yakafanana neyeodhiyo data yekufambisa pombi. Iyo data inofambiswa kuburikidza neBluetooth yakakamurwa kuva anotevera marudzi zvichienderana neiyo encoding fomati:
chii chii SBC
Iyi ndiyo yakajairwa encoding fomati yeBluetooth odhiyo. A2DP (Advanced Audio Distribution Profile) protocol inosungirwa kukodha fomati. Iyo yakanyanya kubvumidzwa mwero ndeye 320kbit / s mune mono uye 512kbit / s mumatanho maviri. Ese maBluetooth audio machipi anozotsigirawo iyi odhiyo encoding fomati.
chii chii AAC
Iyo tekinoroji yakapihwa neDolby Laboratories, ndeye yakakwira compression ratio encoding algorithm. iPhone shandisa AAC fomati yeBluetooth kutapurirana. Parizvino, Apple's Bluetooth audio zvishandiso zvinoshandisa AAC encoding tekinoroji. Uye mazhinji anogashira maturusi akadai seBluetooth speaker / mahedhifoni pamusika anotsigirawo AAC decoding.
chii chii APTX
Ndiyo CSR's patented coding algorithm. Mushure mekunge yatorwa neQualcomm, yakava tekinoroji yayo huru yekukodha. Zvinonzi mune ruzhinji kuti inogona kuwana CD ruzha rwemhando. Mazhinji mafoni matsva eAroid ane APTX. Iyi tekinoroji yekukodha tekinoroji inoshanda kupfuura classical Bluetooth coding, uye kunzwa kwekuteerera kuri nani pane maviri apfuura. Zvishandiso zvinoshandisa tekinoroji yeAPTX zvinoda kunyorera mvumo kubva kuQualcomm uye kubhadhara mutengo wemvumo, uye zvinoda kutsigirwa nezvose zviri zviviri zvekutumira nekugamuchira.
chii chii APTX-HD
aptX HD ndeyepamusoro-tsanangudzo odhiyo, uye mhando yekurira yakada kufanana neLDAC. Iyo yakavakirwa pane yekare aptX, iyo inowedzera chiteshi kutsigira 24 bit 48KHz odhiyo fomati. Zvakanakira izvi zvakaderera chiratidzo-kune-ruzha reshiyo uye kushoma kukanganisa. Panguva imwecheteyo, mwero wekutapurirana unowedzera hongu.
chii chii APTX-LL
aptX LL yakaderera-latency, chinhu chikuru ndechekuti inogona kuwana latency isingasviki makumi mana. Isu tinoziva kuti latency muganho uyo vanhu vanogona kunzwa i40ms, uye kusvika 70ms zvinoreva kuti hatigone kunzwa kunonoka.
chii chii LDAC
Iyi tekinoroji yekukodha tekinoroji yakagadziridzwa neSONY, iyo inogona kufambisa yakakwirira-resolution (Hi-Res) yekuteerera yemukati. Iyi tekinoroji inogona kufambisa zvakapetwa katatu semamwe matekinoroji ekodhi kuburikidza nekodha inoshanda uye yakagadziridzwa sub-packaging Iyo data. Parizvino, tekinoroji iyi inoshandiswa chete muSONY's ega ekutumidzira nekugamuchira michina. Naizvozvo, iyo chete SONY seti yekutumira uye kugamuchira michina inotsigira LDAC odhiyo yekukodha tekinoroji inogona kutengwa kutsigira LDAC-encoded Bluetooth odhiyo data kutapurirana.
Feasycom yakaratidza akati wandei ma module mhinduro anotsigira APTX mafomati. Zvaunogona kuwana pazasi:
Unofungei nezve iyi 6 Yakakura Bluetooth Audio Formats Sumo? Inzwa wakasununguka kutumira kubvunza kune rumwe ruzivo. Ndinokutendai nekuverenga chinyorwa ichi.
