Terminology
Dolby Digital
Dolby Digital is a digital audio compression technology
developed by Dolby Laboratories that allows large quantities of
audio data to be efficiently recorded on discs. It is compatible
with audio signals from mono (1 channel) all the way up to 5.1-
channel surround sound. The signals for the different channels
are completely independent, and since the sound is high quality
digital there is no loss of sound quality.
DTS
This is a home-use digital sound format of the DTS Sound
System. This is a high quality sound system, developed by
Digital Theater Systems Corp for use in movie theaters.
DTS has six independent sound tracks. The theater presentation
is fully realized in the home and other settings. DTS is the
abbreviation for Digital Theater Systems
Dolby Pro Logic II
Dolby Pro Logic II provides multichannel surround sound from
any 2 channel source. It reproduces extended bandwidth
playback with 5.1 channels.
This is made possible by an advanced matrix surround decoder.
This new decoder is able to draw out spatial characteristics of
the recording without adding tonal coloration or artificial delays
that did not exist in the original.
Linear PCM audio
LPCM is a signal recording format used for music CDs. Whereas
music CDs are recorded at 44.1 kHz/ 16 bits, DVDs are recorded
at 48 kHz/16 bits to 96 kHz/24 bits, thereby achieving higher
sound quality than music CDs.
