Advanced MP3/WMA/JPEG and audio CD features
The DV27 DVD player has the ability to handle MP3, WMA and JPEG
files, when these are burned on to a CD-R or CD-RW disc. Picture/
Photo CDs are also playable. These file 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
files. 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 files, 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 files. The following items can be
identified:
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 first valid
file/track, all valid files/tracks on the disc are played, in the order
found.
8
‘PD’ – Play Directory. (CD-ROMs only). Starting from the first
valid file in the current directory, all the (valid) files 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 file name of the track.
bk
When playing CD-ROMs, the full name of the file being played is
displayed here (subject to screen space).
bl
When playing CD-ROMs, tag information from MP3 and WMA
files 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 files/tracks in each directory
(audio-CD tracks or files that can be played) are displayed on the
screen. Pressing PLAY while the cursor is on a valid file/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 files/tracks are
played. Playback must be stopped first. ‘Programme’ mode operates
differently for audio-CDs and MP3 discs, and is explained on page 15.
Playlist mode: The player is in this mode when a programmed
sequence of files/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 file/track is highlighted, the tag
information for that file (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 file/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 files. 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 file names, of up to 64 characters (Joliet standard), are
supported.
Only sample rates of 44.1kHz and 48kHz are supported for MP3
and WMA files.
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 files other than MP3, WMA or
JPEGs, but these are not displayed on the screen.
