Bitstream Audio chinhu chinonyanya kukosha muimba yemitambo - tsvaga nei
Tinotora nguva yatinoteerera kutinhira zvisingabvumirwi, asi kuwana mimhanzi, kukurukurirana, uye manzwiro kubva kunzvimbo kune nzeve dzako zvinoda teknolojia inofanirwa kuita semashiripiti.
Imwe teknolojia inoshandiswa mukuendesa inzwi inonzi Bitstream (aka Bitstream Audio, Bit Stream, Digital Bitstream, kana Audio Bitstream).
Bitstream Defined
A Bitstream ibhenyari bits of information (1's uye 0's) iyo inogona kutamidzwa kubva pane chimwe chinhu kuenda kune imwe. Bitstreams inoshandiswa muPC, networking, uye audio applications.
Pamusoro pekutinhira, chinotyisa chinosanganisira kushandura inzwi mumadhita ejw.org (1 uye 0) uye zvino kutumira mashoko acho kubva kune imwe nzvimbo kubva kune imwe, uye, pakupedzisira, munzeve dzako.
Somuenzaniso, PCM neHi-Res mutinhimira mienzaniso yemutauro inoshandisa mabheji kutumira zviratidzo zvema digital.
Nzira Dzakadzama Inoshandiswa Sei MuItaly Theater
Muimba yemitambo inoshandiswa, chidiki chinonyatsotsanangurwa senzira yekuendesa zviratidzo zvekodhi dzekodha dzemhando dzakasvikidzika dzakapoteredza kubva kune imwe nzvimbo kuenda kumusha unofanirwa kugamuchira mvumo kana AV preamp / processor / Power amplifier combination.
Musha wemitambo yemusha kana AV processor inoona fomu yakapoteredzwa yakapoteredzwa kutumirwa kwairi. Munhu anogamuchira kana AV inogadziridza anobva awedzera kujekesa ruzivo runobva mumirayiridzo inowanikwa muchitinho chechidiki, anowedzera chero humwe humwe huwandu hwekugadziriswa kwemashure, uye pakupedzisira unohutora kuhuwandu hweanalogog kuitira kuti hugone kuwedzerwa uye kutumirwa kune vakurukuri kuitira kuti unzwe it.
Nzira iyo inotangira inotanga nemuumbi wezvakagadzirwa uye / kana injini yeinzwi / mixer. Kuti urongwa hushande hushande, zvakagadzirwa nomusiki / injini inonzwika inotanga kusarudza kuti chii chakakomberedza fomu yepamusoro kuti ishandise pakunyoresa kunyoresa kana kutapurirwa kurarama. Musiki (injini yezvinonzwika, musanganisi) ndiye anowedzera kuvhara mazwi semadhita e digital pane maitiro akasarudzwa maererano nemitemo yemafaira.
Kana imwe nguva yapera, bits iyo inobva yaiswa paDhi (DVD, Blu-ray, Ultra HD Blu-ray), kambani kana kuti sataneti, nzvimbo inotambira, kana kunyange yakaiswa mumutambo weTV unobuda.
Mienzaniso yemafomu akakomberedzwa anoshandiswa ayo anoshandisa nzira yekutambisa kunosanganisira Dolby Digital, EX, Plus , TrueHD , Atmos , DTS , DTS-ES , DTS 96/24 , DTS HD-Master Audio , uye DTS: X.
Izvo zvinenge zvichitsvaga zvinogona kutumirwa kubva kune imwe nzvimbo zvakananga kumusha wemitambo yakagadziriswa (kana AV Preamp / Processor) kuburikidza nehutano hwepanyama ( digital optical, digital coaxial , kana HDMI interface) kubva pane diski yakakodzera, media broader, kana tambo / satellite bhokisi. A bitstream inogonawo kutumirwa pasina wire antenna kana musha.
Mienzaniso yeBitstream Management
Heano mienzaniso yekuti kudengenyeka kwemafirimu kunogona kushanda sei pakusangana kwemitambo yemusha:
- I DVD, Blu-ray, kana Ultra HD disc ine Dolby Digital kana DTS soundtrack iyo inodhidzirwa sedhijititi. Mutambi anofambidzana anofanirwa kuverenga iyi encoding kubva pane disc, kuendesa chiratidzo chekodhi mumutambo wekambani kuburikidza ne digital digiti, digital coaxial, kana HDMI kushamwaridzana ne Home Theater Receiver / AV Preamp Processor ine dolby Digital kana DTS Decoder.Igamuchire, uyewo, inosarudza iyo Dolby Digital kana DTS ichienda mumigwagwa yayo yakakodzera uye inotumira zviratidzo zvinotumirwa kuburikidza nemakwikwi akakodzera, kuitira kuti inzwike nemuteereri kuburikidza nemashoko ekukurukura.
- Mukuwedzera kune nzira iri pamusoro apa yekugadzirisa zvishoma, DVD Blu-ray, kana Ultra HD Disc player inogonawo kupa simba rekuziva kudengenyeka kunobva kubhuku mukati kusvika kuPMM format . Izvi zvinoreva kuti panzvimbo yekutenderera kune anogamuchira kuti uone kutadza kunouya kubva mumutambi, pane dzimwe nguva unogona kusarudza kuti mutambi atume chiratidzo chekare chiri muPPM fomu digitally kumusha wemitambo yekugamuchira mafirimu neHDMI kana kuti mufananisi yeanalogog kuburikidza nehutano hwakasiyana-siyana hweanalogog audio .
- Muzviitiko izvi, vatori vemapurisa voga ndivo vanopfuurirwa uye zviratidzo zvepachena zvinopfuudzwa zvakananga kuburikidza nemupiki kune vanosimudzira uye kune avo vanotaura vasingashandisi kushandiswa kunze kwekuti mutereri ari kuita chero kushandiswa kwepamusoro mukati memusha wemitambo yemusha kana AV preamp / processor.
- Siteshi reTV rinotumira chiratidzo pamusoro pemugwagwa waunenge wapiwa unosanganisira Dolby Digital-encoded bitstream. Terevhizheni inobatana inogamuchira iyo chiratidzo, zvino inoshandura iyo inonzi bhabariti inonyatsopindirana, imba yemitambo yakagamuchirwa, kana pre preamp / protoresor iko kushandisa digital optical output kana HDMI Audio Return Channel . The barbar, imba yemitambo receiver, kana pre preamp / protooror ndiye anonyatsotarisa mhepo uye anotamba chiratidzo checodhodhi. Zvichienderana ne-soundbar, receiver, av preamp / protorer, mushandisi anogonawo kuva nesarudzo yekubatanidza chikwata cheDolby Digital chakatodzwa nehuwandu hwekushandurwa kwezwi.
- Nokushambadzira kwepaIndaneti, basa, rakafanana neNetflix, rinopa purogiramu kana mafirimu akachengetwa muDolby Digital kana yehupenyu hwehupenyu hwepakati. Kana iwe uchigamuchira zvinyorwa izvi uchishandisa media media, uye yakabatanidzwa kumusha wemitambo yemunharaunda uchishandisa digital audio connection (optical, coaxial, HDMI), izwi rinopoteredza audio bitstream rinotumirwa kumumiririri, rinodhindwa, uye rinotumirwa kuburikidza nemagetsi uye vatauri. Saizvozvowo, kana nhepfenyuro yevhidhiyo ichibatanidza zvakananga kuTV neHTMLMI, uye TV iri kushamwaridzana nebhadhiyo inonzwika kana yeimba yekugamuchira mafirimu kuburikidza nehurukuro yema digital kana HDMI Audio Return Channel, terevhizheni ichapfuura nharaunda inotyisa kuburikidza neTV uye kunze kune soundbar / home theater yekududzira uye kukura.
- Mune imwe mamiriro ekutengesa kwepaInternet, unogona kuwana Netflix kana mamwe mabasa zvakananga kuburikidza ne Smart TV . Kana zvakadaro, terevhizheni inogona kukwanisa kuvhara dhidhi yeDolby Digital kumusana webharuti, imba yemitambo yakagadziriswa, kana pre preamp / profanorori achishandisa nzira imwechete apo iyo TV inogamuchira kuparadzirwa kwemasitadhi - kuburikidza ne digital digital kana HDMI Audio Return Channel ye decoding uye chero imwezve yevashandisi nzira yakasarudzwa yekuwedzera kunakidzwa nekuteerera.
The Bottom Line
Bitstream encoding ndiyo teknolojia yakakosha iyo inoshandiswa mumusha wemitambo audio. Inopa nzira yekutsvaga deta-ine nzara yeruzivo rwakanaka rwepakati pakati pechigadziro chemutambo uye musha wemitambo yemuzinda kana AV preamp / protogeri mukati memuganhu wakamanikana uchishandisa nzira dzakasiyana-siyana dzekubatanidza.
