I-DTS-HD I-Master Audio iyinhlangano ephezulu yokufaka ikhodi ye-surround sound encoding eyakhiwe yi-DTS yokusetshenziswa kwendawo yaseshashalazini. Le fomethi isekela iziteshi ezingu-8 zomsindo ozungezayo ngezinga elinyukayo lokuphendula, impendulo ephindaphindiwe yemvamisa kanye nesilinganiso samphakamiso esiphakeme kunezinye izakhiwo ezizungezile ze-DTS . Umncintiswano osondelene kakhulu yi- Dolby TrueHD .
Ngokufanayo ne-Dolby TrueHD, i-Master Audio DTS-HD iqashwe ngokuyinhloko kumafomethi we-Blu-ray Disc ne- Ultra HD Blu-ray futhi isetshenziswe kufomethi ye-HD-ye-DVD ekhishwa manje.
Ukufinyelela i-DTS-HD Master Audio
Isignali ye-DTS-HD yomsindo ingadluliselwa emthonjeni ohambisanayo (njenge-Blu-ray / Ultra HD Blu-ray) ngezindlela ezimbili.
Enye indlela ukudlulisa i-bitstream encoded, ephoqelelwe, nge- HDMI (i-1.3 noma kamuva ) exhunywe kumamukeli wekhamera yasendlini ene-DVD-HD eyakhelwe i-Master Audio decoder. Uma i-decoded, i-receiver idlula isignali ngokusebenzisa izikhulisi, kuzikhulumi ezikhethiwe.
Ungathola futhi i-DTS-HD Master Audio ngokuchaza ukuthi isidlali se-Blu-ray Disc / Ultra HD Blu-ray sinquma isignali ngaphakathi (uma ngabe umdlali unikeza le ndlela). Isignali ekhonjisiwe idluliselwa ngqo kumamukeli wendawo yaseshashalazini njengesiginali se-PCM nge-HDMI, noma, nge-set of 5.1 / 7.1 ukuxhumana kwe-analog audio audio . Kulolu cala, umamukeli akudingeki enze noma iyiphi i-decoding eyengeziwe noma ukucutshungulwa - Ivele idlulisele isignali yomsindo esivele ivele kakade kuma-amplifiers nezikhulumi.
Kumele kuqashelwe ukuthi uma usebenzisa i-decoding yangaphakathi ku-optional uxhumano lokuxhumeka kwe-audio, ukuthi isidlali se-Blu-ray / Ultra HD kufanele sibe nesethi yemiphumela yomsakazo we-analog wesiteshi 5.1 / 7.1, futhi umamukeli womdlalo waseshashalazi kufanele Iqoqo lezinkomba zomsindo we-analog wesiteshi 5.1 / 7.1, zombili zazo manje ezingavamile.
Kubalulekile ukuthi uqaphele ukuthi akuzona zonke izidlali ze-Blu-ray Disc ezihlinzeka ngezinketho zokukhishwa ngaphakathi zangaphakathi ze-DTS-HD - ezinye zingase zinikeze ukucacisa kwangaphakathi kwesiteshi ezimbili, kunokuba zikwazi ukukhipha isiteshi se-5.1.1 noma i-7.1.
Ngaphezu kwalokho, ngokungafani ne-core DTS ifomethi yomsindo ozwakalayo, i-DTS-HD Master Audio (engabhalwanga noma ekhonjisiwe) ayikwazi ukudluliswa nge- Digital Optical noma Digital Coaxial audio connection . Isizathu salokhu ukuthi kunolwazi oluningi kakhulu, ngisho nangenkinga egxilile, kulabo ongakhetha kukho uxhumano ukuze uthole ulwazi lwe-DTS-HD Master Sign signal.
Ukumba I-Deep A Deeper
Uma i-DTS-HD Master i-encoding audio iqashwe, umsindo we-soundtrack u-bit-for-bit ufana nokurekhoda kokuqala okungeke kube khona. Ngenxa yalokho, i-DTS-HD Master Audio efakwe njengefomethi yokulalelwayo yomsindo we-digital "sound Lossless" (isimangalo futhi esenziwe yiDolby Labs ngefomethi yayo ehambisana neDolby TrueHD).
Ngokweqhinga lobuchwepheshe, imvamisa yesampula ye-DTS-HD Master Audio i- 96kHz ekujuleni kwe-24-bit , futhi ifomethi isekela amanani okudlulisa kuma-Blu-ray angu-24.5 mbps , naku-HD-DVD (kulabo abano-HD- Ama-disk e-DVD nabadlali), izinga lokudlulisa liyi-18mbps.
Ngakolunye uhlangothi, i-Dolby TrueHD isekela izinga lokudlulisa elingama-18mbps ku-Blu-ray noma i-HD-DVD.
Nakuba i-DTS-HD Master Audio encode ingakwazi ukuhlinzekela iziteshi ezingu-8 zomsindo (iziteshi ezigcwele ezingu-7 nesiteshi sesiteshi se-subwoofer, singanikezwa njengendlela yesiteshi esingu-5.1 noma isiteshi se-2 uma sikhethwe nguchwepheshe ohlanganisa umsindo (nakuba inketho engu-2 engavamile ukusetshenziswa).
Uma usebenza ngokubambisana nokuqukethwe kwi-Blu-ray Disc, i-disc ingaqukatha umsindo we-DTS-HD Master Audio noma i-soundtrack ye-Dolby TrueHD / Atmos , kodwa okungajwayelekile, uma ukhona, uzothola kokubili izinketho kwi-disc efanayo.
Kodwa-ke, into eyodwa ethakazelisayo ukukhomba ukuthi i-DTS inokuhlakanipha ukwenza i-DTS-HD Master Audio emuva emuva. Lokho kusho ukuthi ngisho noma une-Blu-ray noma i-Ultra HD Blu-ray Disc ekhokhelwe nge-soundtrack ye-DTS-HD ye-Master Audio, usengakwazi ukufinyelela umsindo ohambisanayo we-DTS Digital Surround uma umdlali wakho noma umamukeli wekhamera ekhaya hhayi i-DTS-HD I-Master Audio iyahambisana. Futhi, kulabo abamukelayo yaseshashalazini abangenawo i-HDMI, lokhu kusho ukuthi usengakwazi ukungena endaweni ejwayelekile ye-DTS yedijithali ngokusebenzisa izinketho zokuxhumanisa optical / coaxial.
Okubalulekile
Ungabe uzwa umehluko phakathi kweDTS-HD Master Audio neDolby TrueHD? Mhlawumbe, kodwa kulawo mazinga e-spec, kufanele ube nendlebe enhle ngempela, futhi-ke, amandla okwamukela iseshashalazi ekhaya, izikhulumi, ngisho ne-acoustics yakho yegumbi lizoqala ukudlala umphumela wokulalela wokugcina.
Kanti futhi, ukuthatha izinto ezenzelwe iskripthi, i-DTS iphinde ifake i-DTS: X ifomathi, efaka ukucwiliswa okungaphezulu kune-DTS-HD Master Audio. Ifomethi ingafinyelelwa kuma-Blu-ray / Ultra HD ama-Blu-ray Discs aqoshiwe kahle ne-DTS: Isamukeli semidlalo yaseshashalazini yasekhaya e-X. Ukuze uthole imininingwane eyengeziwe, funda Uhlolojikelele lwe-DTS: X Ifomethi Yomsindo Ephakathi .
