Reference
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 (I-picture)
This is the standard picture and is a complete picture in itself.
This means it has the best picture quality and is the best to use
when adjusting the picture.
P:
Predictive coded picture (P-picture)
This picture is calculated based on past I or P-pictures.
B:
Bidirectionally-predictive coded picture (B-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.
MP3
A method of compressing audio, MPEG Audio Layer 3 (MP3) allows
audio to be reduced to up to one tenth its original size without overtly
hurting audio quality.
When creating MP3 files to play on this unit
≥
Disc formats: ISO9660 level 1 and level 2 (except for extended for-
mats)
≥
Files: MP3 files with the suffix “.mp3” or “.MP3”
≥
This unit is compatible with multi-session but if there are a lot of
sessions it takes more time for play to start. Keep the number of
sessions to a minimum to avoid this.
≥
This unit is not compatible with ID3 tags.
≥
This unit is not compatible with files with a sampling rate of 32 kHz.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and infor-
mation with menus.
Bitstream
This is the digital form of multiple channel audio data (e.g., 5.1 chan-
nel) 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 Labo-
ratories. Apart from stereo (2-channel) audio, these signals can also
be 5.1-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.
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 pic-
ture. 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.
