Additional Information
Region number
DVD players and DVD discs feature region
numbers indicating the area in which they
were purchased. Playback of a DVD is not pos-
sible unless it features the same region num-
ber as the DVD player. This unit's region
number is displayed on the bottom of the unit.
Title
DVD video discs have high data capacity, en-
abling recording of multiple movies on a sin-
gle disc. If, for example, one disc contains
three separate movies, they are divided into
title 1, title 2 and title 3. This lets you enjoy the
convenience of title search and other func-
tions.
VBR
VBR is short for variable bit rate. Generally
speaking CBR (constant bit rate) is more
widely used. But by flexibly adjusting the bit
rate according to the needs of audio compres-
sion, it is possible to achieve compression-
priority sound quality.
WMA
WMA is short for Windows Media™ Audio
and refers to an audio compression technol-
ogy that is developed by Microsoft
Corporation. WMA data can be encoded by
using Windows Media Player version 7 or
later.
Windows Media and the Windows logo are tra-
demarks or registered trademarks of Microsoft
