Dolby Digital
This is a method of coding digital signals devel-
oped 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 the disc using
this method.

Dolby Pro Logic
A surround system where a 4-channel audio
track is recorded as 2 channels and then is re-
stored to 4 channels for play. The surround chan-
nel is monaural and can reproduce up to 7 kHz.

DTS (Digital Theater Systems)
This surround system is used in many movie the-
aters around the world. There is good separation
between the channels, so realistic sound effects
are possible.

Frame still and field still
A still is shown when you pause a moving
picture. A frame still is made up of 2 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.
