Konke Mayelana neDolby TrueHD I-Sound Sound Sound
I-Dolby TrueHD ingenye yefomethi ezenzakalelayo zomsindo ezakhiwe yi-Dolby Labs ukuze zisetshenziswe kwiseyimu yasekhaya.
Ngokuqondile, i-Dolby TrueHD ingaba yinxenye yomsindo we- Blu-ray Disc ne-HD-DVD yokuhlela okuqukethwe. Nakuba i-HD-DVD ivaliwe ngo-2008, i-Dolby TrueHD igcine ubukhona bayo kwifomethi ye-Blu-ray, kodwa umncintiswano wayo ovela ku-DTS obizwa nge- DTS-HD Master Audio , uvame ukusetshenziswa kakhulu.
I-Dolby TrueHD ingakwazi ukusekela kuze kube yiziteshi ezingu-8 zomsindo kuma-96Khz / 24 bits (okuyinto evame ukusetshenziswa kakhulu), noma iziteshi ezingu-6 zomsindo kuma-192kHz / 24 bits (96 noma 192kHz limelela izinga lokulinganisa , kanti ama-bits angu-24 amelela umsindo kancane kancane). Ama-Blu-ray Discs afaka i-Dolby TrueHD angafaka lezo zindlela njengendlela yokudlala yomsakazo we-5.1 noma we-7.1, ekuhlakanipheni kwe-studio ye-movie.
I-Dolby TrueHD ibuye isekele isivinini sokudlulisa idatha kuze kufike ku-18mbps (ukubeka lokhu kube ngombono - wokulalelwayo, okusheshayo!).
I-Lossless Factor
I-Dolby TrueHD (kanye ne-DTS-HD Master Audio), ibizwa ngokuthi amafomethi okungenalutho okulalelwayo. Okushiwo lokhu kungukuthi okungafani ne- Dolby Digital, i-Dolby Digital EX, noma i-Dolby Digital Plus , namanye amafomethi omsindo we-digital, njenge-MP3, uhlobo lokucindezela oluqashiwe oluholela ekulahlekelweni kwekhwalithi yomsindo phakathi komthombo wokuqala, njengoba kubhaliwe, nokuthi yini oyizwayo lapho udlala okuqukethwe emuva.
Ngamanye amazwi, akukho ulwazi olusuka ekurekhodweni kokuqala oluxoshwa ngesikhathi senqubo yokufaka ikhodi Okuzwayo yilokho umdali wokuqukethwe, noma injini ekwazi ukuzwa umsindo kwi-Blu-ray disc, ufuna ukuthi uzwe (Yebo, ikhwalithi uhlelo lwakho lwamahhala yendawo yaseshashalazini lubuye lube nengxenye).
Idokhumenti ye-Dolby TrueHD ifaka phakathi kokusebenza okuzenzakalelayo kwe-Dialog ukusiza ukulinganisa umzila wesiteshi nendawo yonke yokusetha isikhulumi sakho (akusebenzi njalo ngaso sonke isikhathi ukuze usadinga ukwenza ukulungiswa kwezinga lomzila wesiteshi uma kungabonakali kahle ).
Ukufinyelela ku-Dolby TrueHD
Izimpawu ze-Dolby TrueHD zingadluliswa kusuka kumdlali we-Blu-ray Disc ngezindlela ezimbili.
Enye indlela ukudlulisa i-Dolst TrueHD encoded bitstream, ephoqelelwe, nge- HDMI (u-1.3 noma kamuva ) exhunywe kumamukeli womdlalo womdlalo onesidlali se-Dolby TrueHD esakhelwe ngaphakathi. Uma isibonakaliso sinqatshelwe, sidluliselwa kumaphikisi omamukeli kuya kuzikhulumi ezifanele.
Indlela yesibili yokudlulisa isignali ye-Dolby TrueHD ngokusebenzisa isidlali se-Blu-ray Disc ukucacisa isignali ngaphakathi (uma umdlali unikeza le nketho) bese udlulisela isignali ekhethiwe ngokuqondile receiver yaseshashalazini njenge signal PCM nge HDMI, noma, ngokusebenzisa isethi ye- 5.1 / 7.1 yomsakazo we-analog audio audio , uma lokho kutholakala kumdlali. Uma usebenzisa inketho ye-analog ka-5.1 / 7.1, umamukeli akudingeki enze noma yikuphi ukucubungula okunye noma ukucubungula - nje kudlulisela isignali kuma-amplifiers nezikhulumi.
Akuwona wonke abadlali be-Blu-ray Disc abahlinzeka ngokukhetha okukhethwa kukho kwe-Dolby TrueHD yangaphakathi - abanye banganikeza kuphela ukucaciswa kwangaphakathi kwesiteshi, kunokuba kugcwaliswe amandla okukhipha isiteshi okugcwele 5.1 noma 7.1.
Ngokungafani namafomu azungeze i-Dolby Digital ne-Digital EX, i-Dolby TrueHD (engabhalwanga noma engahlehlisiwe) ayikwazi ukudluliswa nge- Digital Optical noma i-Digital Coaxial audio connections ejwayele ukusetshenziselwa ukufinyelela umsindo we-Dolby no-DTS kusuka kuma-DVD nakwezinye okuqukethwe kokusakaza ividiyo. Isizathu salokhu ukuthi kunolwazi oluningi kakhulu, ngisho nangenkathi ecindezelekile, kulabo ongakhetha kukho uxhumano ukuze uthole i-Dolby TrueHD.
Okuningi ku-Dolby TrueHD Ukuqaliswa
I-Dolby TrueHD isetshenziswe ngendlela yokuthi uma isamukeli sekhaya yaseshashalazini singasisekeli, noma uma usebenzisa uxhumano lwe-digital optical / coaxial esikhundleni se-HDMI yomsindo, umsindo we-Dolby Digital 5.1 ozenzakalelayo udlala ngokuzenzakalelayo.
Futhi, kuma-disc-Blu-ray ane-soundtracks ama- Dolby Atmos , uma ungenayo i-receiver yasekhaya ehambisana ne-Dolby Atmos, noma i-Dolby TrueHD noma i-Dolby Digital soundtrack ingafinyelelwa. Uma lokhu kungenziwanga ngokuzenzekela, kungabuye kukhethwe ngemenyu yokudlala ye-Blu-ray Disc ethintekile. Eqinisweni, kuyathakazelisa ukuphawula ukuthi imethadatha ye-Dolby Atmos empeleni ifakwa ngaphakathi kwesignali ye-Dolby TrueHD ukuze ukuhambisana okubuyela emuva kutholakale kalula.
Kuzo zonke imininingwane zobuchwepheshe ezibandakanya ukudalwa nokuqaliswa kwe-Dolby TrueHD, hlola amaphepha amabili amhlophe kusuka ku-Dolby Labs Dolby TrueHD Lossless Audio Performance kanye neDolby TrueHD Audio Coding For Formats Formats .
