I-Bitstream Audio iyinto ebalulekileyo kwikhaya lezemidlalo - fumana isizathu
Sithatha ukhululo apho siphulaphule umsindo ovulekile, kodwa ukufumana umculo, intetho, kunye nemisindo evela kumthombo kwiindlebe zakho kudinga ubuchwepheshe obunokubonakala bufana nomlingo.
Enye iteknoloji eqeshwe ekuhambiseni isandi ibizwa ngokuba yi- Bitstream (aka Bitstream Audio, Bit Bit, i-Bitstream Digital, okanye i-Bitstream Audio).
Bitstream Defined
I-Bitstream ibinzana leenkcukacha zobuninzi (1 kunye ne-0) ezingadluliselwa ukusuka kwisixhobo esinye ukuya kwesinye. I-Bitstreams isetyenziswe kwi-PC, inethiwekhi kunye nezicelo zomsindo.
Kwi-audio, i-bitstream ibandakanya ukuguqula umsindo kwiibitshi zedijithali zolwazi (1 kunye ne-0) uze uthumele loo nkcazelo kwisixhobo somthombo kummkeli, kwaye, ekugqibeleni, ezindlebeni zakho.
Ngokomzekelo, i- PCM kunye ne- Hi-Res yomsindo yimimiselo yomsindo osebenzisa izibhengezo zokudlulisa iimpawu zomculo zedijithali.
Indlela I-Bitstream Eyasetyenziselwa Kwimidlalo Yasekhaya
Kwiimfuno zesekhaya, i-bitstream ichazwe ngokucacileyo njengendlela yokudlulisa iimpawu zomsindo ezifakwe kwiikhomputha zomsindo ojikelezayo ezivela kumthombo ukuya kumkeli ohambelana nesekhaya okanye i- AV preamp / proxy / Power amplifier inhlanganisela.
I-home receiver receiver okanye i-processor ye-AV ifumanisa ifomathi yeenxa zonke ezithunyelwe kuso. Umproceiver okanye i-AV processor ke uqhubeka ukuhlaziya ulwazi olusekelwe kwimimiselo enikezelwe kwisigxina soxinzelelo, ungeze nayiphi na enye eyongezelelweyo yokupasa, kwaye ekugqibeleni uyaguqulela kwifomu ye-analog ukuze ikhutshwe kwaye ithunyelwe kwiithethi ukuze uva .
Inkqubo yokuqalisa iqala ngomqambi womxholo kunye / okanye ingunjineli / umxube wezandi. Ukuze i-bitstream isebenze, umqambi womxholo / unjiniyela wezandi uqala isigqibo malunga nefomathi ephilileyo esetyenziswayo ukuze urekhode umsindo okanye uhanjiso oluphilayo. Umdali (injini yomsindo, umxubeki) uya kuqhubeka ukufaka i-audio njengama-digital bits kwifomati ekhethiweyo ngokwemiqathango yesakhiwo.
Emva kokuba le nkqubo isigqityiwe, ii-bits zibekwe kwiDiski (iDVD, Blu-ray, Ultra HD Blu-ray), ikhebula okanye isevisi ye-satellite, umthombo wokusasazwa, okanye udibaniswe kwi-TV ehambayo.
Imimiselo yeefomathi ezizungezile ezisebenzise inkqubo yokudlulisa i- Dollar Digital, i-EX, i- TrueHD , i- Atmos , i- DTS , i- DTS-ES , i- DTS 96/24 , i- DTS HD-Master Audio , kunye ne-DTS: X.
I-bitstream efunekayo ingathunyelwa ukusuka kumthombo ngqo kwi-host receiver (okanye i-AV Preamp / iProducer) ngokusebenzisa uxhumano lomzimba (i- digital optical, i-digital coaxial , okanye i- HDMI interface) ukusuka kumdlali wediski, i-mediaerer okanye i-cable / satellite ibhokisi. I-bitstream ingathunyelwa nge-wireless nge-antenna okanye kwinethiwekhi yasekhaya.
Imizekelo yoLawulo lwe-Bitstream
Nazi izibonelo zendlela ukuhanjiswa kwe-audio edityanisiweyo kusebenza kwindawo yokusekwa kwetater:
- I-DVD, i-Blu-ray, okanye i-Ultra HD iqulethe i-Dolby Digital okanye i-DTS soundtrack ekhowudiweyo njenge-digital bits. Umdlali ohambelanayo kufuneka afunde le khowudi ye-disc, uthumele isalathisi ekhowudiweyo kwifom ye-bitstream ngokusebenzisa i-digital optical, digital coaxial, okanye i-HDMI uxhumano kwi-Home Receiver Receiver / AV Preamp Processor eneDolby Digital okanye iDododer Decoder. kwakhona, idibanisa i-Dolby Digital okanye i-DTS kwi-assignments yayo yesiganeko esifanelekileyo kwaye ithumela iimpawu zesebe ezinikeziweyo ngokusebenzisa izikhululo ezifanelekileyo, ukwenzela ukuba ivezwe ngumphulaphuli ngokusebenzisa i-loudspeakers.
- Ukongezelela kwindlela ekhankanywe apha ngasentla yokulawula i-bitstream, i-DVD Blu-ray, okanye i-Ultra HD player idlala nayo inokunika amandla ukucacisa ukuhamba okuvela kwidiski ngaphakathi kwifom yePMM. Oku kuthetha ukuba esikhundleni sokuxhomekeka kummkeli ukucacisa umgangatho ovela kumdlali, kwezinye iimeko unako ukukhetha ukuba umdlali athumele isalathisi eselungele ikhowudi kwifom ye-PCM kwidilesi yecala lasekhaya nge-HDMI okanye kwifom ye-analog ngokusebenzisa ukudibanisa kwe- analog ye-analog .
- Kule meko, i-decoders ye-receiver iyagqitywa kwaye isignali yomsindo idluliselwa ngqo ngokufumana i-receiver ukuya kuma-amplifiers kunye nakwizithethi ngaphandle kokuqhutyelwa phambili ngaphandle kokuba umphulaphuli enze isebenze nayiphi na inkqubo eyongezelelweyo kwi-home receiver reception okanye AV preamp / processor.
- Isitishi seTV sisithumela isalathisi phezu kwesitya sayo esabelwe iquka iDolby Digital-encoded bitstream. Umabonwakude ohambelanayo ufumana loo mqondiso, ngoko uthumela umgca wecala kwi-barbar yesixhobo, i-receiver home receiver, okanye i-pre preamp / protocolor usebenzisa i-digital optical output okanye i- HDMI Audio Return Channel . Ibha yomgca, i-home receiver receiver, okanye ipro preamp / proseror ke idibanise i-bitstream kwaye idlale isignali ekhethiweyo. Ngokuxhomekeka kwibharki ye-sound, umkeli, i-pre preamp / iprosesor, umsebenzisi unokukhetha kwakhona ukudibanisa isiphumo seDolby Digital ngokuchithwa komsindo.
- Ukuthungelwano lwe-intanethi, inkonzo, njenge-Netflix, inikeza inkqubo okanye i-movie efakwe kwiDolby Digital okanye ifomathi ehambelana nesandi. Ukuba ufumana loo mxholo usebenzisa umgcini weendaba, kwaye ixhunyiwe kumkeli womdlalo wekhamera usebenzisa uxhulumaniso lwamadivaysi yedijithali (i-optical, coaxial, i-HDMI), i-surroundstream audio sound surrounds isithunyelwe kummkeli, ichongiwe, kwaye ithunyelwe nge-amplifier kunye nezithethi. Ngokufanayo, ukuba umsakazo weendaba udibene ngqo kwi-TV nge-HDMI, kwaye iTV ixhunyiwe kwibha yomsindo ohambelanayo okanye i-home receiver receptor ngokusebenzisa i-digital audio output okanye nge-HDMI Audio Return Channel, i-TV iya kudlula isignali ehamba phambili ngeTV kwaye uphume kwi-barbar yesixhobo / indlu yaseshashalazini yokucoca kunye nokukhulisa.
- Kwimeko ethile yokusasazwa kwe-intanethi, unokufumana iNetflix okanye ezinye iinkonzo ngokuthe ngqo kwi- Smart TV . Ukuba kunjalo, i-TV inokwazi ukudlula isalathisi seDolby Digital encoded kwi-barbar, i-home receiver receiver, okanye i-pre preamp / protocolor isebenzisa iindlela ezifanayo njengokuba i-TV ithola ukusasazwa kwesitishi-nge-digital optical okanye i-HDMI Audio Return Channel. ukucacisa kunye nayiphi na inkqubo eyongezelelweyo yomsebenzisi okhethwe yintando yokuphulaphula.
Ngaphantsi
I-Bitstream encoding yi-teknoloji ephambili esetyenziswe kwi-home audio theater. Inika indlela yokudlulisa ulwazi oluneenkcukacha ezizungezile zedatha phakathi kweso sixhobo kunye nesipredishithi se-AV okanye iprojekti ngaphakathi kwindlela yokunciphisa iqhosha ngokusebenzisa iindlela ezahlukeneyo zonxibelelwano.
