Yintoni i-LDAC?
I-LDAC yitekhnoloji yekhowudi yomsindo engenazingcingo ephuhliswe nguSony. Yathi yatyhilwa okokuqala kwi-CES Consumer Electronics Show ka-2015. Ngelo xesha, u-Sony wathi iteknoloji ye-LDAC yayisebenza ngokuphindwe kathathu kune-encoding ye-Bluetooth kunye nenkqubo yoxinzelelo. Ngale ndlela, ezo fayile zomsindo ezinesisombululo esiphezulu aziyi kuxinzelelwa ngaphezulu xa zithunyelwa ngaphandle kwamacingo, okuya kuphucula kakhulu umgangatho wesandi.
Xa uhambisa i-LPCM yomsindo we-high-resolution, iteknoloji ye-LDAC igcina ubunzulu bayo obuphezulu kunye noluhlu lokuphendula rhoqo, ivumela ukuhanjiswa kwekhwalithi ephezulu nakwi-96kHz / 24bit yomsindo. Ngokwahlukileyo, itekhnoloji yeBluetooth yendabuko yokuhambisa iaudio, ngaphambi kokuhambisa i-LPCM yomsindo, xa uhambisa idatha yeaudiyo, into yokuqala ekufuneka uyenzile "kukuthoba" ividiyo enesisombululo esiphezulu kumgangatho weCD we-44.1 kHz / 16 bit, kwaye emva koko uyidlulisele. ngokusebenzisa 328 kbps, nto leyo eya kubangela isixa esikhulu ilahleko ulwazi, ngenxa KABINI. Okunokukhokelela kwesi siphelo: umgangatho wokugqibela wesandi umbi kakhulu kunomgangatho wokuqala weCD.
KODWA, obu buchwephesha bunokusetyenziswa kuphela kwizixhobo zikaSony.
Yintoni iAptX?
I-AptX ngumgangatho we-codec yomsindo. Umgangatho udityaniswe neBluetooth A2DP stereo transmission protocol protocol. Umgangatho wekhowudi yomsindo weBluetooth westereo yile: I-SBC, eyaziwa ngokuba yi-narrowband coding, kunye ne-aptX ngumgangatho omtsha wekhowudi owaziswa yiCSR. Ngaphantsi kwemeko ye-SBC encoding, ixesha lokulibaziseka lokuhanjiswa kwe-Bluetooth stereo lingaphezu kwe-120ms, ngelixa i-aptX encoding standard inokunceda ukunciphisa i-latency ukuya kwi-40ms. Ukulibaziseka abantu abaninzi banokuziva xa i-latency ingaphezulu kwe-70ms. Ke ngoko, ukuba umgangatho we-aptX wamkelwe, umsebenzisi akayi kuziva ukulibaziseka kokwenene kokusetyenziswa, njengamava okubukela iTV ngokuthe ngqo ngeendlebe ezingenanto.
I-Feasycom, njengomnye wababoneleli besisombululo seBluetooth, iphuhlise iimodyuli ezintathu ezithandwayo zeBluetooth nge-aptX, iteknoloji ye-aptX-HD. Kwaye bona:
Ngexesha elizayo xa ukhangela isisombululo seprojekthi yakho yomsindo engenazingcingo, ungalibali CELA UNCEDO ku-FEASYCOM!
