English
On a JPEG disc, each still picture is recorded as a file. Files
are usually grouped into a folder. Folders can also include
other folders, creating hierarchical folder layers.
This unit simplifies the hierarchical construction of a disc and
manages folders by “groups.”
• This unit can recognize and play back up to 150 files per
group and up to 99 groups per disc. Files whose numbers
exceed 150 and groups whose numbers exceed 99 cannot
be played back.
7 Playback Control function (PBC)—VCD and
SVCD only
The Playback Control function enables menu-driven operation.
Menu-driven playback
A selection menu is displayed when you start playing a VCD
and SVCD with the Playback Control feature. The selection
menu shows a list of numbers for selection. Some discs may
show moving pictures or a divided screen.
You can interact with the screen using a menu display to
select and play an entry.
See the example illustration below about basic feature of
menu-driven playback (for details about the operation
through the menu, see also page 38).
Note:
• While operating a VCD or SVCD using the menu, some of the
functions such as repeat play may not work.
7 Disc structure
DVD VIDEO consists of “titles,” and each title may be
divided into some “chapters.”
For example, if a DVD VIDEO contains some movies, each
movie may have its own title number and it may be further
divided into some chapters. In a DVD VIDEO Karaoke, each
song may have its own title number, but it may not be further
divided into chapters.
DVD AUDIO consists of “groups,” and each group may be
divided into some “tracks.”
Some DVD AUDIOs also contain a “bonus group” that can be
played back by entering the “key number” (a kind of
password). Usually the contents of “bonus group” are not
open to the public.
Note that most DVD AUDIOs include much information in
addition to audio, such as still pictures, movies, and text.
VCD, SVCD, and CD consist of “tracks.”
In general, each track has its own track number. (On some
discs, each track may also be divided by Indexes. This unit is
not compatible with Index function.)
On an MP3 disc, each song is recorded as a file. Files are
usually grouped into a folder. Folders can also include other
folders, creating hierarchical folder layers.
This unit simplifies the hierarchical construction of a disc and
manages files and folders by “tracks” and “groups.”
• This unit can recognize and play back up to 150 tracks per
group and up to 99 groups per disc. Tracks whose
numbers exceed 150 and groups whose numbers exceed
99 cannot be played back.
