q Dolby Digital
Dolby Digital is the multi-channel digital signal format
developed by Dolby Laboratories.
Dolby Digital consists of up to “5.1” channels – front left,
front right, center, surround left, surround right, and an
additional channel exclusively reserved for additional deep
bass sound effects (the Low Frequency Effects – LFE
channel, also called the “.1” channel, containing bass
frequencies of up to 120 Hz).
Unlike the analog Dolby Pro Logic format, Dolby Digital’s main
channels can all contain full range sound information, from the
lowest bass, up to the highest frequencies – 22 kHz. The
signals within each channel are distinct from the others,
allowing pinpoint sound imaging, and Dolby Digital offers
tremendous dynamic range from the most powerful sound
effects to the quietest, softest sounds, free from noise and
distortion.

w Dolby Pro Logic II
Dolby Pro Logic II is a new multi-channel playback format
developed by Dolby Laboratories using feedback logic steering
technology and offering improvements over conventional Dolby
Pro Logic circuits.
Dolby Pro Logic II can be used to decode not only sources
recorded in Dolby Surround ( ) but also regular stereo sources
into five channels (front left, front right, center, surround left
and surround right) to achieve surround sound.
Whereas with conventional Dolby Pro Logic the surround
channel playback frequency band was limited, Dolby Pro Logic
II offers a wider band range (20 Hz to 20 kHz or greater). In
addition, the surround channels were monaural (the surround
left and right channels were the same) with previous Dolby Pro
Logic, but Dolby Pro Logic II they are played as stereo signals.
Sources recorded in Dolby Surround
These are sources in which three or more channels of surround
have been recorded as two channels of signals using Dolby
Surround encoding technology.
Dolby Surround is used for the sound tracks of movies recorded
on DVDs, LDs and Video cassettes to be played on stereo
VCRs, as well as for the stereo broadcast signals of FM radio,
TV, satellite broadcasts and cable TV.
Decoding these signals with Dolby Pro Logic II makes it
possible to achieve multi-channel surround playback. The
signals can also be played on ordinary stereo equipment, in
which case they provide normal stereo sound.
There are two types of DVD Dolby surround recording signals.
