Konke Odinga Ukukwazi Nge-LE Audio

Yini i-LE Audio?

I-LE Audio iyizinga elisha lobuchwepheshe bomsindo elethulwa yi-Bluetooth Special Interest Group (SIG) ngo-2020. Isekelwe ku-Bluetooth low-energy 5.2 futhi isebenzisa izakhiwo ze-ISOC (isochronous). I-LE Audio yethula i-LC3 audio codec algorithm, enikeza ukubambezeleka okuphansi kanye nekhwalithi yokudlulisela ephezulu. Iphinde isekele izici ezinjengokuxhumana kwamadivayisi amaningi kanye nokwabelana komsindo, ukunikeza abathengi umuzwa ophakeme womsindo.

Izinzuzo zomsindo we-LE uma ziqhathaniswa ne-Bluetooth Yakudala

I-LC3 Codec

I-LC3, njengekhodekhi eyisibopho esekelwa yi-LE Audio, ilingana ne-SBC kumsindo we-Bluetooth wakudala. Ilungele ukuba yikhodekhi evamile yomsindo we-Bluetooth wesikhathi esizayo. Uma kuqhathaniswa ne-SBC, i-LC3 inikeza:

• I-Higher Compression Ratio (Ukubambezeleka okuphansi): I-LC3 inikeza isilinganiso esiphezulu sokucindezela uma kuqhathaniswa ne-SBC kumsindo we-Bluetooth wakudala, okuholela ekubambezelekeni okuphansi. Ngedatha ye-stereo ku-48K/16bit, i-LC3 ifinyelela isilinganiso sokucindezelwa okuphezulu kokuthembeka okungu-8:1 (96kbps), kuyilapho i-SBC ngokuvamile isebenza ku-328kbps kudatha efanayo.
• Ikhwalithi Yomsindo Engcono: Ku-bitrate efanayo, i-LC3 idlula i-SBC ngekhwalithi yomsindo, ikakhulukazi ekuphatheni amaza aphakathi nokuya kokuphansi.
• Ukusekelwa kwamafomethi omsindo ahlukahlukene: I-LC3 isekela izikhawu zozimele ezingu-10ms no-7.5ms, 16-bit, 24-bit, kanye namasampula omsindo angama-32-bit, inombolo engenamkhawulo yamashaneli omsindo, namaza esampula angu-8kHz, 16kHz, 24kHz, 32kHz, 44.1, 48kHz kanye no-XNUMXkHz.

I-Multi-Stream Audio

• Ukusekela Okuningi Okuzimele, Ukusakazwa Komsindo Okuvumelanisiwe: Umsindo osakazwa kaningi uvumela ukudluliswa kokusakazwa komsindo okuzimele okuningi, okuvumelanisiwe phakathi kwedivayisi yomthombo womsindo (isb, i-smartphone) kanye nedivaysi eyodwa noma ngaphezulu yokwamukela umsindo. Imodi ye-Continuous Isochronous Stream (CIS) isungula ukuxhumeka kwe-Bluetooth ACL okunamandla aphansi phakathi kwamadivayisi, iqinisekisa ukuvumelanisa okungcono kwe-True Wireless Stereo (TWS) nokubambezeleka okuphansi, okuvunyelanisiwe komsindo wokusakaza okuningi.

Sakaza Isici Somsindo

• Ukusakaza Umsindo Kumadivayisi Angenamkhawulo: Imodi yokusakaza ye-Isochronous Stream (BIS) ku-LE Audio ivumela idivayisi yomthombo womsindo ukuthi isakaze ukusakaza okulalelwayo okukodwa noma okuningi enanini elingenamkhawulo lamadivayisi amukela umsindo. I-BIS yakhelwe izimo zokusakaza okulalelwayo zomphakathi, njengokulalela i-TV buthule ezindaweni zokudlela noma izimemezelo zomphakathi ezikhumulweni zezindiza. Isekela ukudlalwa komsindo okuvumelanisiwe kudivayisi ngayinye eyamukelayo futhi inike amandla ukukhethwa kokusakaza okuthile, njengokukhetha ithrekhi yolimi kusilungiselelo setiyetha ye-movie. I-BIS ayiqondile, ilondoloza ukushintshaniswa kwedatha, inciphisa ukusetshenziswa kwamandla, futhi ivula amathuba amasha abengafinyelelwa ngaphambilini ngokusetshenziswa kwe-Bluetooth yakudala.

Imikhawulo ye-LE Audio

I-LE Audio inezinzuzo ezifana nekhwalithi yomsindo ephezulu, ukusetshenziswa kwamandla okuphansi, ukubambezeleka okuphansi, ukusebenzisana okuqinile, nokusekelwa kokuxhumana okuningi. Kodwa-ke, njengobuchwepheshe obusha, nayo inemikhawulo yayo:

• Izinkinga Zokuhambelana Kwedivayisi: Ngenxa yobuningi bezinkampani embonini, ukumiswa kanye nokwamukelwa kwe-LE Audio kubhekana nezinselelo, okuholela ezinkingeni zokuhambisana phakathi kwemikhiqizo ehlukene ye-LE Audio.
• Amabhodlela Okusebenza: Ubunkimbinkimbi obuphezulu be-LC3 kanye ne-LC3 kanye ne-codec algorithms bubeka izimfuno ezithile emandleni okucubungula ama-chip. Amanye ama-chips angase asekele iphrothokholi kodwa alwele ukuphatha izinqubo zokufaka ikhodi nokuqopha kahle.
• Amadivayisi Asekelwe Okukhawulelwe: Njengamanje, kunamadivayisi ambalwa uma kuqhathaniswa asekela i-LE Audio. Yize imikhiqizo ye-Flagship evela kumadivayisi eselula kanye nabakhiqizi bama-headphone sebeqalile ukwethula i-LE Audio, ukushintshwa okuphelele kusazodinga isikhathi. Ukubhekana naleli phuzu lobuhlungu, i-Feasycom yethule ngendlela entsha imojuli yokuqala ye-Bluetooth emhlabeni esekela kokubili i-LE Audio kanye ne-Classic Audio ngesikhathi esisodwa, okuvumela ukuthuthukiswa kokusha kokusebenza komsindo we-LE ngaphandle kokufaka engozini ulwazi lomsebenzisi Lomsindo Wakudala.

Izicelo ze-LE Audio

Ngokusekelwe ezinhlelweni ezihlukahlukene ze-LE Audio, ikakhulukazi i-Auracast (ngokusekelwe kumodi ye-BIS), ingasetshenziswa ezimweni eziningi zomsindo ukuthuthukisa umuzwa wabasebenzisi womsindo:

• Ukwabelana Komsindo Womuntu Siqu: I-Broadcast Isochronous Stream (BIS) ivumela ukusakazwa komsindo okukodwa noma ngaphezulu ukuthi kwabelwane ngenani elingenamkhawulo lamadivayisi, okuvumela abasebenzisi ukuthi babelane ngomsindo wabo nama-headphones abasebenzisi abaseduze besebenzisa ama-smartphone noma amathebulethi abo.
• Ukulalela Okuthuthukisiwe/Okusizayo Ezikhaleni Zomphakathi: I-Auracast ayisizi nje kuphela ukuhlinzeka ngokuphakelwa okubanzi kwabantu abangezwa futhi ithuthukise ukutholakala kwezinsizakalo zokulalela ezisizayo kodwa futhi yandisa ukusebenza kwalezi zinhlelo kubathengi abanamazinga ahlukahlukene empilo yokuzwa.
• Ukusekelwa Kwezilimi Eziningi: Ezindaweni lapho abantu bezilimi ezahlukene bebuthana khona, njengezikhungo zenkomfa noma amasinema, i-Auracast inganikeza ukuhumusha ngesikhathi esisodwa ngolimi lwangempela lomsebenzisi.
• Amasistimu Womhlahlandlela Wokuvakasha: Ezindaweni ezifana namamyuziyamu, izinkundla zemidlalo, nezindawo eziheha izivakashi, abasebenzisi bangasebenzisa ama-earbud noma ama-headphone ukuze balalele ukusakazwa komsindo wokuvakasha, banikeze umuzwa ogxile kakhulu.
• Izikrini ze-TV ezithule: I-Auracast ivumela abasebenzisi ukuthi balalele umsindo ovela ku-TV uma ungekho umsindo noma lapho ivolumu iphansi kakhulu ukuthi bangayizwa, ithuthukisa umuzwa wezivakashi ezindaweni ezifana nezindawo zokuzivocavoca namabha ezemidlalo.

Amathrendi Azayo E-LE Audio

Ngokwezibikezelo ze-ABI Research, ngo-2028, umthamo wonyaka wokuthunyelwa kwamadivayisi asekelwa yi-LE Audio uzofinyelela ezigidini ezi-3, futhi ngo-2027, u-90% wama-smartphones athunyelwa minyaka yonke azosekela i-LE Audio. Ngokungangabazeki, i-LE Audio izothuthukisa uguquko kuyo yonke inkambu yomsindo we-Bluetooth, idlulele ngale kokudluliswa komsindo okujwayelekile kuzinhlelo zokusebenza eziku-inthanethi Yezinto (IoT), amakhaya ahlakaniphile, nezinye izindawo.
