sizes of a displayed image. The horizontal vs. vertical
ratio of conventional TVs. is 4:3, and that of widescreens
is 16:9.
AUDIO OUT Jacks: Jacks on the back of the DVD
System that send audio to another system (TV, Stereo,

Bit Rate: The amount of data used to hold a given
length of music; measured in kilobits per seconds, 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.
