Glossary
Bitstream
This is the digital form of multi-channel audio data {e.g., 5.1 channel)
before it is decoded into its various channels.
Decoder
A decoder restores the coded audio signals on DVDs to normal. This is
called decoding.
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.
Frame still and field still
Frames are the still pictures that go together to make a moving picture.
There are about 30 frames shown each second.
One frame is made up of two fields, A regular television shows these fields
one after the other to create frames.
A still is shown when you pause a moving picture. A frame still is made up
of two alternating fields, so the picture may appear blurred, but overall
quality is high. A field still is not blurred, but it has only half the information
of a frame still so picture quality is lower.
Interlace and progressive output
NTSC, the video signal standard, has 480 interlaced (t) scan lines,
whereas progressive scanning uses twice the number of scan lines. This is
called 480p. The video signals output from this unit’s COMPONENT
VIDEO OUT terminals (Y, P
b , P r ) allow you to enjoy higher quality pictures
than if the signals were output from the VIDEO OUTPUT terminal or S
VIDEO OUT terminal.
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.
Pi 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.
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.
Linear PCM (pulse code modulation)
These are uncompressed digital signals, similar to those found on CDs. ^

Playback control (PBC) 5
If a Video CD has playback control, you can select scenes and information ^
with menus (called menu play in these instructions). ■
