Dolby Digital, unlike “matrixed”
systems (such as Dolby Pro

sound from a two-channel
source, is capable of delivering

In the encoding process, the
DTS algorithm encrypts six
channels of 20-bit digital audio
imformation in the space
previously allotted for ouly two
channels of 16-bit linear PCM.
Then during playback, the DTS
decoder reconstructs the
original six channels of 20-bit
digital audio.
