Glossary
Analog audio: Sound that has not been
turned into numbers. Analog sound is
available when you use the AUDIO LEFT/
RIGHT jacks. These red and white jacks send
audio through two channels, the left and
right.
Aspect ratio: Aspect ratio refers to the
length to height ratio of TV. The ratio of a
standard TV is 4:3, while the ratio of a high-
defi nition or wide TV is 16:9. The letter box
allows you to enjoy a picture with a wider
perspective on a standard 4:3 screen.
Bit Rate: The amount of data used to hold
a given length of music; measured in kilobits
per second, or kbps. Or, the speed at which
you record. Generally, the higher the bit
rate, or the higher the recording speed, the
better the sound quality. However, higher bit
rates use more space on a disc.
Chapter: Sections of a picture or a music
piece on a DVD that are smaller than titles.
A title is composed of several chapters. Each
chapter is assigned a chapter number
enabling you to locate the chapter you want.
