Izwi elizungezile liyingxenye ebalulekile yokuhlangenwe nakho kwendawo yaseshashalazini, futhi ngaleyo ndlela, kunamafomethi amaningi aphikisayo azungezile asetshenziswayo, ngokuya ngamakhono akho womsindo, isakhiwo sesikhulumi, nokuqukethwe.
Mhlawumbe okusetshenziselwa kakhulu amafomethi ayingxenye yomndeni weDolby Digital. Kulesi sihloko, sixoxisana ezintathu zazo: i-Dolby Digital, i-Dolby Digital EX, ne-Dolby Digital Plus, evame ukusetshenziswa kuma-DVD nokuqukethwe kokusakaza, futhi ikhona njengokukhethwa kokungeziwe kokuqukethwe kwe-Blu-ray Disc.
Yini i-Dolby Digital eyiyona
I-Dolby Digital iyisistimu yokufaka ikhodi ye-digital yedijithali yama-DVD, ama-Blu-ray Discs, futhi, kwezinye izimo, ngokusakazwa kwe-TV noma ukusakaza okuqukethwe, okuhlinzeka ngokudluliselwa okuphumelelayo kwamasignali alalelwayo angase akhiwe ngeyodwa, noma iziteshi ezingaphezulu ihlonishwa yisamukeli sekhaya yaseshashalazini noma i- AV Preamp / Processor nge-Dolby Digital futhi isakazwa kumakheli oyedwa noma ngaphezulu.
Cishe bonke abamukelayo yaseshashalazini abasetshenzisiwe basebenzisa i-Dolby Digital encoder encane futhi wonke ama- DVD ne- Blu-ray Disc abadlali banamakhono okudlula izibonakaliso zeDolby Digital kumamukeleki afanelekile wokucubungula.
I-Dolby Digital ivame ukubizwa ngokuthi isistimu ezungeza isiteshi esingu-5.1 . Nokho, kufanele kuqaphele ukuthi igama elithi "i-Dolby Digital" libhekisela kukhodidi yedijithali yesignali yomsindo, hhayi ukuthi zingaki iziteshi. Ngamanye amazwi, i-Dolby Digital ingaba:
- I-monophonic - Emele isikhulumi esisodwa noma ezimbili. Nokho, ngezikhulumi ezimbili, zombili ziveza okufanayo umsindo, ngakho umsindo uzovela ovela esikhaleni phakathi kwezipikha.
- I-2-Isiteshi - Emele izikhulumi ezimbili - enye ngakwesobunxele futhi ngakwesokudla kwesimo sokulalela.
- Isiteshi se-4 - esiboniswe yizikhulumi ezine - Amabili abekwe ngaphambili kwesokunxele nangakwesokudla sokulalela, futhi amabili ngakwesobunxele nangakwesokudla, futhi ngemuva kwesimo sokulalela.
- Iziteshi ezingu-5.1 - Ezimele izikhulumi ezinhlanu (ezansi kwesokunxele, phakathi, kwesokudla, kwesobunxele, kwesokudla), kanye ne-subwoofer ( .1 )
I-Dolby Digital EX
6.1 Iziteshi - I-Dolby Digital EX ineza isiteshi sesithathu esizungezile esabekwa ngqo ngemuva kokulaleli. Imelelwe izikhulumi eziyisithupha (kwesokunxele, isikhungo, kwesokudla, kwesokunxele esikuzungezile, esiphakathi ngemuva, okuzungezile kwesokudla), ne-subwoofer (.1.). Lokhu kuletha inani leziteshi ezifinyelela ku-6.1.
Ngamanye amazwi, umlaleli unomzila wesiteshi sangaphambili, futhi ngeDolby Digital EX, isiteshi sesiteshi sangemuva. Uma ulahlekelwa ukubalwa, iziteshi zibhalwe phansi: I-Front Front, Isikhungo, Ngakwesokudla, Esizungezile Ngakwesobunxele, Esizungezile Ngakwesokudla, I-Subwoofer, ne-Surround Back Center (6.1) noma i-Surround Back Left kanye ne-Surround Back Right (okungenzeka ibe yodwa isiteshi - ngokwe-decoding ye-Dolby Digital EX). Umamukeli wendawo yaseshashalazini ne-Dolby Digital EX isimemezelo esidingekayo ukuze athole isipiliyoni esigcwele sesiteshi se-6.1.
Kodwa-ke, uma unayo i-DVD, noma okunye okuqukethwe komthombo, okuqukethe i-encoding engu-6.1 yesiteshi EX futhi umamukeli wakho akanakho ukucaciswa kwe-EX, lowo owamukelayo uzozenzakalela ku-Dolby Digital 5.1 angakwazi ukuhlanganisa ulwazi oluthe xaxa ngaphakathi kwensimu yomsindo wesiteshi esingu-5.1.
I-Dolby Digital Plus
7.1 Amashaneli - I-Dolby Digital Plus iyinhlangano ephezulu ehambisana nedijithali ehambisana nendawo ehambisana nedijithali esekela iziteshi ezingu-8 zokumiswa kokuzungezile, kodwa ibuye iqukethe i-Dolst Digital 5.1 encane ehambisana ne-receiver standard-equipped equipped.
I-Dolby Digital Plus ingenye yamafomethi amaningi alalelwayo aklanyelwe futhi asetshenziswa ngefomethi ye-Blu-ray Disc. I-Dolby Digital Plus iyahambisana nengxenye yomsindo ye-interface ye- HDMI , futhi isetshenziselwa ukusakaza kanye nezinhlelo zokusebenza zomsindo weselula futhi iphinde ibe yesikhulumi se-Dolby Audio se-Windows 10 nesiphequluli se-Microsoft Edge.
