Zvikonzero nei Bluetooth inogona kuderedza Mhando yehutano
Bluetooth yakakurumidza kuva nzira yakajairika yekunakidzwa nemisidhoni isina mheya kuburikidza nevakurukuri uye headphones. Zvisinei, chimwe chinhu chinoshushikana kuti vamwe vane maonero eBluetooth uye zvakanyanya kuderedza kunaka kwehutano. Kune avo vanofunga kuti - kubva pane manzwiro ekutendeseka ekutenderera - iwe nguva dzose uri nani pakusarudza imwe ye Wi-Fi-based wireless technologies , zvakadai se AirPlay, DLNA, Play-Fi, kana Sonos.
Kunyange zvazvo kutenda kwakadaro kwakarurama, pane zvakawanda zvekushandisa Bluetooth pane iwe unogona kuziva.
Bluetooth yakatanga kusimbiswa kwete yevaraidzo yemutauro, asi kubatanidza makhesi efoni uye speakerphone. Yakanga yakagadzirwawo nebandwende rakatetepa, iyo inoisimudza kuti ishandise kudhinda kwedhidhiyo kune chiratidzo chekunzwa. Kunyange zvazvo izvi zvichigona kunge zvakanyatsonaka pakukurukurirana kwefoni, hazvisi zvakanaka kumimhanzi kubereka. Kwete chete izvozvo, asi bluetooth inogona kushandisa iri kudzvinyirira pamusoro pekunyorwa kwemashoko ingangodaro iripo, yakadai kubva kumadhidhi ehurukuro ehurukuro kana zvitubu zvinoparadzirwa kuburikidza neInternet. Asi chimwe chinhu chinokosha chokuyeuka ndechokuti bluetooth system haifaniri kushandisa iyi kuwedzera kuwedzera. Heino chikonzero nei:
Mafaira ose eBluetooth anofanira kutsigira SBC (inomirira Low Complexity Subband Coding). Zvisinei, mabhidhiyo eBluetooth anogonawo kutsigira codecs dzinosarudzwa, dzinogona kuwanikwa muBluetooth Advanced Audio Distribution Profile (A2DP) tsanangudzo.
Izvo zvinokonzerwa nekodecs zvakanyorwa ndezvi: MPEG 1 & 2 Audio (MP2 ne MP3), MPEG 3 & 4 (AAC), ATRAC, uye aptX. Kujekesa zvishoma zveizvi: Inowanzozivikanwa MP3 format ndeyechokwadi MPEG-1 Chitsauko 3, saka MP3 inoputirwa pasi pechirangaridzo sechinhu chakanaka chodec. ATRAC inonzi codec yakashandiswa zvikuru mumikhiqizo yaSon, kunyanya muD MiniDisc digital recording format.
Ngatitarisei mitsara miviri kubva kuA2DP spec sheet, iyo inogona kuwanikwa seyodhadhi yepa PDF paBluetooth.org.
4.2.2 Zvisarudzo zveCodecs
Chigadzirwa chacho chinogonawo kutsigira Optional codecs kuti kuwedzere kushandiswa kwayo. Apo zvose zviviri SRC neSNK zvinotsigira imwecheteyo codec inosarudzwa, iyi codec inogona kushandiswa panzvimbo yeIndaneti codec.
Muchirongwa ichi, SRC inoreva chigadziro chemhepo, uye SNK inoreva kunyura (kana kuenda kune imwe nzvimbo). Saka iyo inogona kuva iyo smartphone yako, tablet, kana kombiyuta, uye kunyura kwaizova yako hurukuri yeBluetooth, headphones, kana kugamuchira.
Izvi zvinoreva kuti Bluetooth haifaniri kunge ichiwedzera kuwedzerwa kwemashoko kune zvinhu zvatove zvakanyanyiswa. Kana zvose zviripo uye zvigadziri zvirongwa zvinotsigira codec inoshandiswa kuvhara chiratidzo chepakutanga, audio inogona kutumirwa uye kugamuchirwa pasina kuchinjwa . Saka, kana uchiteerera ma MP3 kana maAAC mafaira wawakachengeta pa smartphone yako, piritsi, kana kombiyuta, bluetooth haifaniri kuderedza kunaka kwezwi kana zvipfeko zvose zviri kutsigira iyo fomu.
Murairo uyu unoshandawo kune internet inhare uye inotambira mimhanzi mimhanzi inowedzerwa mu MP3 kana AAC, inosanganisira zvakawanda zvezviripo nhasi. Zvisinei, mamwe mimhanzi mitsva ave achiongorora mamwe maitiro, zvakadai sekuti Spotify anoshandisa sei Ogg Vorbis codec .
Sezvo huwandu hwetaneti huwandu hwetachikwata huchiwedzera nekufamba kwenguva, tinogona kuona zviri nani uye zviri nani munguva pfupi iri mberi.
Asi maererano neBluetooth SIG, sangano rinobvumira bluetooth, kushandiswa kunoramba kuripo kwazvino. Ndiko kunyanya nokuti foni haikwanisi kuparidzira mimhanzi chete asiwo mabheti nezvimwe zviziviso zvine chokuita nefoni. Kunyange zvakadaro, hapana chikonzero chokuti mugadziri aisagona kuchinja kubva kuSBC kusvika ku MP3 kana kuAAC kushandiswa kana chipikisi cheBluetooth chinowitsigira. Nokudaro zviziviso zvingadai zvakave nokushandiswa kwacho, asi chizvarwa che MP3 kana maAAC zvingadarika zvisina kuiswa.
Zvakadini neAptX?
Unhu hwe stereo audio kuburikidza neBluetooth yakavandudzwa nekufamba kwenguva. Chero ani anoziva zviri kuitika muBluetooth akanzwa nezvekodhi codec , iyo inotengeswa sechikwidziro kusvika kune chinonzi SBC codec. Kutaura kuti mukurumbira weAptX ndiko kukwanisa kwayo kuburitsa "CD-like" yehutano hwepamusoro pamusoro peBluetooth wireless. Ingoyeuka kuti zvose zviri mukati maBluetooth uye zvinogadzirisa zvigadzirwa zvinofanira kusimbisa codec aptX kuitira kuti ibatsirwe. Asi kana iwe uri kutamba MP3 kana maAAC zvinhu, muumbi anogona kunge ari nani kushandisa shanduko yemutauro wepakutanga faira redio kunze kwekuwedzerwa zvakare ku-encoding kuburikidza neAptX kana SBC.
Yakawanda yeBluetooth audio mishonga haisiwe nekambani iyo vashandi varo vanopfeka marashi avo, asi neODM (yakagadzirwa nemuumbi wekutanga) iwe hauna kumbonzwa. Uye mutambi weBluetooth akashandisa mune chigadzirwa chemhanzi zvichida hachina kuumbwa neODM, asi nemumwe mugadziri. Vaya vanga vari mumabhizimisi vanodzidza kuti zvakanyanya kuoma chigadzirwa chemagetsi, uye kana pane vamwe vanjiniya vanoshanda pazviri, zvinowanzove kuti hakuna munhu anoziva zvose pamusoro pezviri kuitika mukati memutambo. Chimwe chimiro chinogona kutorwa nyore nyore kune chimwe, uye iwe hauzombozvizivi nokuti hazvive nehutachiona hwekugamuchira Bluetooth huchakuudza kuti iyo inopinda mafaira chii.
CSR, iyo kambani inoshandisa cptec aptX, inotaura kuti signal yeAptX yakave yakagadzirirwa inonzwika zviri pachena pamusoro peBluetooth link. Kunyange zvazvo aptX iri rudzi rwekumanikidzika, inofanirwa kushanda nenzira isinganyanyi kukosha kutendeseka kwevhangeri (zvichienderana nemamwe nzira yekunyanya).
AptX codec inoshandisa purogiramu yakaderera yekuderedza nzira iyo inodzokorora huwandu hwehuwandu hwehurukuro iyo ichibvumira kuti data ienderane kuburikidza neBluetooth "pipe" pasina wire. Nhamba ye data inofananidzwa neyomumhanzi CD (16-bit / 44 kHz), saka nei boka racho richienzanisa aptX ne "CD-like" inzwi.
Asi zvakakosha kuzive kuti nhanho imwe neimwe mumaketani ehurukuro inobata kubuda kwezwi. I-aptX codec haikwanise kubhadhara mitero yepamusoro-soro / vatauriri, mafaira e-audio-resolved audio / sources, kana hutsika dzakasiyana dzevashanduri ve -digital-to-analog (DACs) inowanikwa mumagetsi. Inzvimbo yekuteerera inofanirwa kuongororwawo zvakare. Chero kutendeseka kunowanikwa kuburikidza neBluetooth neAptX kunogona kuvharwa neruzha, zvakadai sekushandisa midziyo / HVAC, motokari yemotokari, kana kuti kukurukurirana kwepedyo. Nezvo mupfungwa, zvingave zvakakosha kusarudza maBlue speakers zvichienderana nezvinhu uye headphones zvichibva mukunyaradza panzvimbo yekodec inoenderana.
Zvakakosha kuziva kuti nepo bluetooth (sezvinowanzoshandiswa) inoderedza hutano hwehutano (kune zvidimbu zvakasiyana), haifaniri. Zvinonyanya kusvika kune vashandi vekushandisa kushandisa Bluetooth nenzira inobata mararamiro ehurukuro zvishoma - kana zvichida, kwete zvachose. Zvino unofanirwa kufungidzira kuti kusiyana kwepachivande pakati pemakodhi ehurukuro kunogona kuva kwakaoma kunzwa, kunyange pane imwe nzira yakanaka chaizvo. Mune mamiriro ezvinhu akawanda, bluetooth harizove nechinonyanya kukosha pahutano hwehutano hwekombiyuta. Asi kana iwe uchinge wakagadzikana uye uchida kubvisa kusava nechokwadi kwose, iwe unogona kugara uchinakidzwa nemimhanzi nekubatanidza zvinyorwa uchishandisa tambo yekuridza .
