Advanced MP3/WMA/JPEG and audio CD features
The DV78 DVD player has the ability to handle MP3, WMA and
JPEG les, when these are burned on to a CD-R or CD-RW disc.
Picture/Photo CDs are also playable. These le types may be
mixed together, if desired.
This section explains the more sophisticated CD-based features,
for audio CDs and for CD-ROM discs containing MP3, WMA and
JPEG les. The operation for audio-CDs and other CD-ROMs is
very similar, except that CD-ROMs can have directories and sub-
directories, while audio-CDs do not have a directory structure.
In this section of the document, we use the term ‘CD-ROM’ to
refer to a CD-R or CD-RW disc containing MP3, WMA or JPEG
les, and including Picture/Photo CDs.
All of these advanced features use on-screen menus, so a TV
monitor is required.
Screen layout
When an audio-CD or CD-ROM is detected by the DVD player,
the disc navigator screen is displayed.
The screen shown above is the disc navigator screen, in this
example showing a CD-R containing MP3 les. The following
items can be identied:
1
The user command indicator.
2
The mode of the player. This is described in more detail
below.
3
The current track number and the total number of tracks
in this directory (for CD-ROMs), or on the whole disc (for
audio-CDs).
4
The playback time of the current track, and the total
playback time.
5
For CD-ROMs, this area shows the current directory.
6
‘Up’ – for CD-ROMs, selecting this button changes
directory to one level above the current one. This button
is not shown for audio-CDs, or if the current directory is at
the top level.
7
‘PAF’ – Play All Files on the disc. Starting from the rst
valid le/track, all valid les/tracks on the disc are played,
in the order found.
8
‘PD’ – Play Directory. (CD-ROMs only). Starting from the
rst valid le in the current directory, all the (valid) les in
the current directory are played.
9
The names of the tracks in this directory. For audio-CDs,
the text ‘Track 1’, etc., is shown here. For CD-ROMs, the
text shown here is based on the le name of the track.
bk
When playing CD-ROMs, the full name of the le being
played is displayed here (subject to screen space).
bl
When playing CD-ROMs, tag information from MP3 and
WMA les is displayed here, if present on the disc.
bm
Helpful messages to the user are displayed here. When
the disc is loaded, the PAF button (
7
) is highlighted. This
means that loading the disc and pressing PLAY or OK is
enough to set the disc playing.
Player mode
When playing audio-CDs or CD-ROMs, the player can be in one
of three modes:
Browse mode: the user is free to navigate around the disc
directory structure (while playback is stopped). Valid les/tracks
in each directory (audio-CD tracks or les that can be played) are
displayed on the screen. Pressing PLAY while the cursor is on a
valid le/track will start playback from that point, continuing to the
end of the disc. Alternatively, the ‘PD’ or ‘PAF’ buttons can be used
to start playback.
Programme mode: Press PROG on the remote control to enter
‘Programme’ mode to choose the order in which the les/tracks
are played. Playback must be stopped rst. ‘Programme’ mode
operates differently for audio-CDs and MP3 discs, and is explained
on page 19.
Playlist mode: The player is in this mode when a programmed
sequence of les/tracks is being played. No navigation of the
disc may be performed in this mode; the player starts at the
beginning of the programmed playlist and plays through to the
end.
Browsing the disc (Browse mode)
By default, the disc navigator is in ‘Browse’ mode. In this mode,
the user can navigate around the disc (using the cursor pad
for direction and ‘OK’ to select an option). When a le/track
is highlighted, the tag information for that le (if available)
is displayed in the lower portion of the screen. Use the ‘Up’
button to move to a higher-level directory; to enter a lower-level
directory, press OK when the directory name is highlighted.
At any time, press PLAY or OK to begin playback from the
le/track highlighted currently. Navigation around the current
directory is possible during playback, but playback stops
automatically if you attempt to navigate out of the current
directory. Please note the following:
Fast forward and fast rewind do not work with MP3 or
WMA playback.
Skipping forward past the end of a directory with
CD-ROMs causes playback to continue from the next
directory containing valid les. Skip-back can be
performed only as far as the beginning of the current
directory.
Directory trees may be up to 10 directories deep.
Long le names, of up to 64 characters (Joliet standard),
are supported.
Only sample rates of 44.1kHz and 48kHz are supported
for MP3 and WMA les.
For MP3 playback, the following constant bit rates are
supported: 32, 64, 80, 96, 112, 128, 160, 192, 256
and 320 kilobits per second. Variable bit rate (VBR)
between 96kb/s and 320kb/s is also supported.
For WMA playback, the following constant bit rates are
supported: 48, 64, 80, 96, 128, 160 and 192kb/s.
CD-ROM discs may contain les other than MP3, WMA or
JPEGs, but these are not displayed on the screen.
