This format comprises of stereo rear channels 
and a discrete subwoofer channel. DTS provides

a worldwide standard of digital compression 
technology. The picture data is compressed to 
about 1/40 of its original size. DVD also uses 
variable rate coding technology that processes 
allocated data according to the status of the 
picture.
The audio data is recorded in Dolby Digital as 
well as in PCM, allowing you to enjoy more 
realistic audio presence.
