Glossary
Decoder
A decoder restores the coded audio signals on DVDs to normal.
This is called decoding.
DivX
A video compression format developed by DivXNetworks, Inc. that
compresses video files without any considerable loss of video quality.
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.
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. This unit can
determine which type has been used, then uses the most suitable
method of progressive output.
For PAL
Film is 25 frames per second.
Video is 50 fields per second (two fields making up one frame).
For NTSC
Film is 24 or 30 frames per second, with motion picture film generally
being 24 frames per second.
Video is 60 fields per second (two fields making up one frame).
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.
Progressive/Interlace
The PAL video signal standard has 625 interlaced (i) scan lines,
whereas progressive scanning, called 625p, uses twice the number of
scan lines. For the NTSC standard, these are called 525i and 525p
respectively.
Using progressive output, you can enjoy the high-resolution video
recorded on media such as DVD-Video.
Your television must be compatible to enjoy progressive video.
I/P/B
MPEG 2, the video compression standard adapted 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.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and
information with menus.
MPEG4
A compression system for use on mobile devices or a network, that
allows highly efficient recording at a low bit rate.
Sampling frequency
Sampling is the process of converting the heights of sound wave
(analog signal) samples taken at set periods into digits (digital encoding).
Sampling frequency is the number of samples taken per second, so
larger numbers mean more faithful reproduction of the original sound.
