Glossary
Bitstream
The digital form of multi-channel data (e.g.
5.1 channel) before decoding.
Decoder
A decoder restores coded audio signals on DVDs
to normal.
Dolby Digital
This is a method of coding digital signals
developed by Dolby Laboratories. Apart from
stereo (2-channel) audio, these signals can also
be multi-channel audio. A large amount of audio
information can be recorded on one disc using
this method.
Dolby Pro Logic
A surround system where a 4-channel audio
track is recorded as 2 channels and then is
restored to 4 channels for play. The surround
channel is monaural and can reproduce up to 7
kHz.

DTS (Digital Theater Systems)
This surround system is used in many movie
theaters around the world. There is good
separation between the channels, so realistic
sound effects are possible.
Dynamic range
Dynamic range is the difference between the
lowest level of sound that can be heard above
the noise of the equipment and the highest level
of sound before distortion occurs.
Film and video
DVD-Videos are recorded using either film or
video. Usually, film is recorded at 24 frames per
second, the rate movies are filmed at, while
video is recorded at 30 frames per second.
Frame still and field still
Frames are the still pictures that make moving
pictures. About thirty are shown each second. A
frame still may appear blurred but overall quality
is high.
Two fields appear alternately to make up one
frame. A field still is not blurred but picture quality
is lower.

Interlace and progressive output
NTSC, the video signal standard, has 480
interlaced (I) scan lines, whereas progressive
scanning uses twice the number of scan lines.
This is called 480P.
I/P/B
MPEG 2, the video compression standard
adopted for use with DVD-Video, codes frames
using these 3 picture types.
I: Intra coded picture
This picture has the best quality and is the
best to use when adjusting the picture.
P: Predictive coded picture
This picture is calculated based on past I or
P-pictures.
B: Bidirectionally-predictive coded picture
This picture is calculated by comparing past
and future I and P-pictures so it has the
lowest volume of information.
Linear PCM (pulse code modulation)
These are uncompressed digital signals, similar
to those found on CDs.
