Frames are the still pictures that go together to make a moving
picture.
There are about thirty 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.

MPEG 2, the video compression standard adopted for use with
DVD, codes frames using these three 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 and 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.

A decoder restores the coded audio signals on DVDs to normal.
This is called decoding.

This is a method of coding digital signals developed by Dolby
Laboratories. The signals are highly compressed, enabling a large
amount of information to be recorded on one disc.

This is a method of coding digital signals developed by Digital
Theater Systems. The signals are compressed at a low ratio to
maintain sound quality.

This is the number of samples of sound taken per second during
conversion to a digital signal. Sampling frequency is expressed in
kilohertz (kHz). A high sampling frequency results in a sound close
to the original when played back.

PCM is the usual digital method used for music CDs. DVDs have a
greater volume so they use linear PCM, which has a higher
sampling rate.
The compressed version of this is called Packed PCM (PPCM).

This is the digital form of multiple channel audio data (e.g., 
5.1 channel) before it is decoded into its various channels.

This is the smallest division on DVD-Audio, CDs and Video CDs
and usually equates to a single song.

This is the smallest division on DVD-Video and is roughly equivalent
to a track.

The tracks on DVD-Audio are divided up into groups. The method of
grouping depends on the disc.

This is the largest division on DVD-Video.

This method of controlling disc play is included on version 2.0 Video
CDs. You are able to interact with the disc through menus.

MP3 refers to the type of music file that is compressed using MPEG
1 audio layer 3.
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.
