DivX

Video is an encoder/decoder based on the MPEG-4 com-
pression system which is used to encrypt and display compressed
video data.
This enables the HDD DVD player to play back videos compressed
in the DivX

format. This results in playback quality with fewer arte-
facts and higher compression.

Video files have, for example, the suffix AVI. DivX

Video data
is packaged in the AVI file along with audio data compressed in
MP3 format. This means:

Video and MP3 audio form the AVI file.

MP3 CD features
MP3 stands for MPEG-1 Audio Layer 3 and comes from the Motion
Picture Expert Group (MPEG) standard, which was developed for
compressing film data.
The MP3 format enables audio files to be saved on a computer with
a sound quality similar to that of a CD. This only requires about
10 % of the original data quantity. The standard encoding bit rate
for MP3 files is 128 kbps. Generally, the higher the bit rate of an
MP3 file, the better the sound quality.
Most MP3 files on the Internet are encoded at 128 or 160 kbps.
160 kbps is considered CD quality.
MP3 files can be downloaded from the Internet and then burned
onto a CD-ROM. Your HDD DVD recorder can read the ID3 tag
from the file header, which contains information on the song and
the artist, and displays this in the info menu/status display.
MP3 CDs contain sound recordings. They can be played in the
normal manner on an audio system. The digital signals transmitted
during MP3 playback are PCM encoded, regardless of the audio
output setting. The signals are output with the same data rate as the
music source (possibilities are: 32 kbps – 320 kbps, usually:
128 kbps).
MP3 files can be organised into folders and subfolders similar to
files on a computer.
