Konke malunga neDolby TrueHD I-Sound Sound Sound
I-Dolby TrueHD yenye yeefomathi ezizungezile zeefomathi eziphuhliswe yiDolby Labs ukusetyenziswa kwiseyaterari yasekhaya.
Ngokukodwa, i-Dolby TrueHD inokuba yinxenye yomsindo we- Blu-ray Disc ne-HD-DVD yokuqulunqwa komxholo. Nangona i-HD-DVD yaphela ngo-2008, i-Dolby TrueHD igcine ubukho bayo kwifomathi ye-Blu-ray, kodwa umncintiswano wayo othe ngqo kwi-DTS obizwa ngokuba yi- DTS-HD Master Audio , isetyenziswa ngokuqhelekileyo.
I-Dolby TrueHD inokuxhasa ukufikelela kumaziko angama-8 we-audio kwi-96Khz / 24 bits (eqhelekileyo isetyenziswe), okanye kwii-6 iziteshi zomsindo kuma-192kHz / 24 bits (96 okanye i-192kHz ibonisa izinga lesampulu , ngelixa ii-bits ezingama-24 zimela i-audio bunzulu). I-Blu-ray Discs ezibandakanya i-Dolby TrueHD inokufaka ezo zikhetho njenge-soundtrack ye-5.1 okanye 7.1, kwi-studio ye-studio.
I-Dolby TrueHD iphinde ixhase ukuhamba kwedatha ukuya kwi-18mbps (ukubeka oku ngqiqo - kwi-audio, ekhawulezayo!).
I-Lossless Factor
I-Dolby TrueHD (kunye ne-DTS-HD Master Audio), zibhekiswa njengezakhiwo ezingenasiphelo zomsindo. Oko kuthetha ntoni ukuba ngokungafani neDolby Digital, i-Dolby Digital EX, okanye i-Dolby Digital Plus , kunye nezinye iifomati zomsindo zedijithali, ezifana ne-MP3, uhlobo lokuxinwa luqeshwe oluphumela ekulahlekelweni kwexabiso lokulahla phakathi komthombo wokuqala, njengoko kubhaliweyo, kunye noko uvelayo xa udlala umxholo kwakhona.
Ngamanye amazwi, akukho lwazi oluvela kwirekhodi lokuqala lukhutshwe ngexesha lekhowudi yokudibanisa Oko uvelayo yintoni umdali womxholo, okanye injiniya eyayiqonda i-soundtrack kwi-Blu-ray disc, ufuna ukuba uyive (Kakade, umgangatho isimiso sakho somsindo esisekhaya sikwenza inxaxheba).
I-Dolby TrueHD encoding iquka ukuzenzekela ngokuzenzekelayo Ukudibanisa i-Dialog Normalization ukuncedisa ukulinganisa igalaji yeziko kunye nayo yonke isethaphu sakho sokuseta (akusebenzi ngaso sonke isikhathi usebenza kakuhle ukuze usenokufuna ukwenza olunye ulungelelaniso lwezinga lezithuthi ukuba ingxoxo ingabonakali kakuhle ).
Ukufikelela kwiDolby TrueHD
Izibonakaliso zeDolby TrueHD zingadluliselwa kwi-Blu-ray Disc player ngeendlela ezimbini.
Enye indlela ukuhambisa i-Dolby TrueHD encoded bitstream, eneenkomfa, nge- HDMI (enoba 1.3 okanye kamva ) ixhunywe kumkeli womncedisi wekhaya onokwakheka kweDolby TrueHD eyakhelwe. Emva kokuba uphawu luchongiwe, luyadluliselwa ukusuka kumamkeli owamkela kwisithethi ezichanekileyo.
Indlela yesibini yokuthumela uphawu lweDolby TrueHD kukusebenzisa umdlali we-Blu-ray Disc ukuba ahlaziye uphawu ngaphakathi (ukuba umdlali unika oku khetho) kwaye udlulisele isignali echongiwe ngqo kwi-host receiver njenge-PCM isignali nge-HDMI, okanye, ngokusebenzisa isethi ye- 5.1 / 7.1 yesalathisi ye-analog audio audio , ukuba loo khetho ifumaneka kumdlali. Xa usebenzisa i-5.1 / 7.1 ye-analog inketho, umamukeli akadingi ukwenza nayiphi na i-decoding eyongezelelweyo okanye ukucubungula - iphela idlulisela isignali kwi-amplifiers and speakers.
Akunabo bonke abadlali be-Blu-ray Disc enikela iinketho zangaphakathi zeDolby TrueHD zangaphakathi - ezinye ziza kunika i-decoding yangaphakathi-yesibini, ngaphandle kwe-5.1 epheleleyo okanye ye-7.1.
Ngokungafani ne-Dolby Digital kunye ne-Digital EX ifom ezandiwayo, i-Dolby TrueHD (ingahlawulwanga okanye ingeniswa) ayikwazi ukudluliselwa nge- Digital Optical okanye iDock Digital Coaxial ekhompyutheni eziqhelekileyo zisetyenziselwa ukufikelela kwisandi seDolby ne-DTS esivela kwiiDVD kunye nokunye okuqukethwe kwevidiyo. Isizathu salokhu kukuba kukho ulwazi oluninzi, kwimeko exinyiweyo, kulezo zixhobo zokuxhamla ukuhlala kwiDolby TrueHD.
Ngaphezu kweDolby TrueHD Ukuphunyezwa
I-Dolby TrueHD isetyenziswe ngendlela yokuba ukuba i-receiver yakho yasekhaya iyakwakuxhasi, okanye ukuba usebenzisa i-digital optical / coaxial uxhumano endaweni ye-HDMI yomsindo, i-Dolby Digital 5.1 idlala ngokuzenzekelayo.
Kwakhona, kwi-Blu-ray disks ezinee- soundtracks zentetho ye-Dolby Atmos , ukuba awunayo i-receiver ye-Dolby Realmos yemiboniso yekhaya, okanye i-Dolby TrueHD okanye i-Dolby Digital soundtrack ingafumaneka. Ukuba oku kungenziwa ngokuzenzekelayo, kunokukhethwa kwakhona kwimenyu yokudlala ye-Blu-ray Disc affected. Enyanisweni, kuyathakazelisa ukuqaphela ukuba imetadata yaseDolby Atmos imiselwe ukuba ibekwe kwisalathisi seDolby TrueHD ukwenzela ukuba ukuhambelana ngokulandelelana kubonakala lula.
Kuzo zonke iinkcukacha zobugcisa ezibandakanya indalo kunye nokuphunyezwa kweDolby TrueHD, khangela amaphepha amabini amhlophe avela kwiDolby Labs Dolby TrueHD Ukusebenza okungenasiphelo komsindo kunye neDolby TrueHD UkuCodesha kweeNkcukacha zeeFomathi zoLonwabo ezizayo .
