DVD VIDEO

Typically, DVD VIDEO discs are made up of larger units called

AtitlesB. Each title has a number (title number) that can be used to select desired titles. Titles are further divided into units called AchaptersB. 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 (a single chapter). However, 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. (A pg. 27)

When you record a program on a DVD-R/RW (Video mode) disc

A single recording session results in a single title (a single chapter). However, chapter marks are automatically inserted when recording is paused, or audio changes due to commercial breaks, etc. It is also possible to insert chapter marks at desired locations during either recording or playback. Once the disc has been finalized, these chapter marks are deleted and new chapter marks are assigned automatically approximately every 5 minutes.

DirectoryMP3 fileJPEG fileFile 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 250 files 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. (A pg. 28)

●Regarding the contents recorded on discs

Some files may not be played back depending on the file types and other factors.
