1.4 Main Applications
TheDP570canbesuccessfullydeployedwhereverthereisaneedtomonitorthequalityof
digitalaudio,andtoreviewexistingmetadata.Itiscurrentlymostcommonintwo
applications:
•DVDmastering
• CreationandbroadcastofDTVcontent
1.4.1 Use in DVD Mastering
ADVDauthoristypicallypreparingmixedaudioforwritingtotheDVD:generating
metadata,verifyinglevels,andauditioningdownmixes.Thisprocessisdescribedindetail
inUsingtheDP570inDVDMasteringonpage 43.
1.4.2 Use in Digital Television

DP570inLiveRemoteBroadcastonpage 47.
Atthereceivingendofthistransmission,theDolbyEstreamisdecodedbacktobaseband
audioandmetadata.Theaudioprogramandthemetadataaremonitored,altered,or

postproductionstudioandpassesthroughthetelevisionstationtoMasterControl,where
manyincomingDolbyEstreamsareonceagaindecodedbacktotheirindividualbaseband
digitalaudio/metadataprograms.Theaudioprogram/metadatapairthatisselectedtoair
issenttothetransmissionDolbyDigitalencoder,whichencodestheincomingaudio
programaccordingtothemetadatastreamassociatedwithit,therebysimplifyingthe

Finally,theDolbyDigitalsignalisdecodedintheconsumer’shome,withmetadata
