Glossary

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.

Film and video

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.

WMA, MP3, and CD text information

¡Discs must conform to ISO9660 level 1 or 2 (except for extended formats).

¡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.

¡The order tracks appear in the menus may differ to the order

shown on your computer.

WMA

¡Noise may occur when playing WMA files.

¡You cannot play WMA files that are copy protected.

MP3

¡This unit is not compatible with ID3 tags.

¡If you play an MP3 track that includes still picture data, it will take some time before the music itself starts playing and the elapsed time will not be displayed during this time. Even after the track starts, the correct play time will not be displayed.

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.

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.

Give folders and files names

3-digit number prefixes in the order you want to play them.

Extension

004track.wma (or .WMA)

The extension for MP3 is

“.mp3” or “.MP3”.

	NTSC, the video signal standard, has 480 interlaced (I) scan lines,
	whereas progressive scanning uses twice the number of scan lines.
Reference	This is called 480P. The video signals output from this unit’s
	COMPONENT VIDEO OUT terminals (Y, PB, PR) allow you to enjoy
	higher quality pictures than if the signals were output from the
	VIDEO OUT 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.

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.

CD (CD text only)

When making your own CD text discs

The unit plays the tracks in the order you record them so you do not have to give titles number prefixes.

TM

WMA is a compression format developed

by Microsoft Corporation. It achieves the Windows

same sound quality as MP3 with a file size that is smaller than that of MP3.
