40 MP3 Playback
MP3 is a compression technology. MP3 compresses large digital music files, making
them up to 10 times smaller without losing significant sound quality. MP3 has become a
standard audio compression format on the world wide web, allowing quick and easy
transfer of audio or music files on the Internet. As a file storage solution, it allows you
to store tracks on your computer's hard disk without using too much space. You can
then transfer your Tracks from your computer onto a CD Recordable or CD
Rewritable disc, then play that Disc on this DVD Player.
Tracks that are compressed or recorded with MP3 technology will have a computer
file name that ends in .mp3.
You may either purchase MP3 recordings (digital) or record your own MP3 music
(analog) using your personal computer. (You will need MP3 recording software.
Materials and equipment with which to make MP3 recordings are not supplied with
this DVD Player. Check with your retailer for details about MP3, or visit the Philips
web site at www.philips.com.)
This chart compares the sound quality of MP3 recordings based on the speed, or bit
rate, at which they were recorded. Keep these characteristics in mind when making
Discs that you intend to play on the DVD Player.

Comments
Slow Bit Rates let you compress
more and use less space, but sound
quality is significantly affected.
The Bit Rates and used space are
acceptable. The sound quality is good.
Fast Bit Rates provide quality recordings,
but use a lot of disc space.
