File Structure Of Discs
DVD VIDEO
Typically, DVDVIDEO discs are made up of larger units called
“titles”. Each title has a number (title number) that can be used to
select desired titles. Titles are further divided into units called
“chapters”. Each chapter has a number (chapter number) that can
also be used to select desired chapters. Note that some discs are
not divided into titles and chapters.
When you record a program on a DVD-RAM/RW (VR mode)
disc
A single recording session results in a single title. In addition,
chapter marks are automatically inserted when recording is
paused, or audio changes from monaural to stereo due to
commercial breaks, etc. It is also possible to insert chapter marks
at desired locations during playback. (Apg. 25)
When you record a program on a DVD-R/RW (Video mode)
disc
A single recording session results in a single title. Marks are
assigned automatically approximately every 5 minutes during
recording. In addition, chapter marks are automatically inserted
when recording is paused, or audio changes from monaural to
stereo due to commercial breaks, etc. It is possible to insert
chapter marks at desired locations during playback. Once the disc
has been finalized, these chapter marks are deleted and new
chapter marks are assigned automatically approximately every
5minutes.
●In Video mode, even before finalizing, it is impossible to perform
editing operations other than changing the disc name and/or title
names and deleting programs and/or titles.
●After finalizing, it is impossible to perform editing operations.
Audio CD/Video CD/SVCD
Typically, Audio CD discs are divided into separate tracks each
containing one song. Each track is assigned a number. For
example, the third track is Track3. The same is true for Video CD/
SVCD discs.
However, some discs are not divided into tracks.
JPEG/MP3 Disc (CD-R/RW/ROM)
MP3/JPEG files put in directories nested in several levels on a disc
will be organized as if they were put in single level directories
(groups) by the MP3/JPEG Navigation of this unit. (Apg. 52)
File structure of a disc before starting the MP3/JPEG
Navigation
File structure of the disc after starting the MP3/JPEG
Navigation
Files are automatically grouped as follows and displayed on the
MP3/JPEG Navigation screen. Data is displayed in the
alphabetical order of file name. Files are grouped based on roots.
●This unit can recognize up to 9 hierarchies including directories
and files.
Also, it can recognize up to 250files in each group, and up to
99 groups on a disc.
NOTES:
●Video CD/SVCD discs that support Playback Control (PBC)
The contents of a disc are recorded into several hierarchies, and
played back according to the instructions on the screen while
navigating through the hierarchies. It is also possible to playback
recorded tracks consecutively without activating the PBC function
even when playing a PBC-compatible disc. (Apg.26)
●Regarding the contents recorded on discs
Some files may not be played back depending on the file types
and other factors.
