DVD Player Operations

English

7Disc 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.

	Title 1			Title 2
Chapter 1		Chapter 2	Chapter 3	Chapter 1	Chapter 2

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.

Group 1			Group 2
File 1		Group 3
	File 2			Group 4	Group 5

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.

	Group 1			Group 2
Track 1		Track 2	Track 3	Track 1	Track 2

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.)

Track 1 Track 2 Track 3 Track 4 Track 5

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.

7Playback 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.

Group 1			Group 2
Track 1		Group 3
	Track 2			Group 4	Group 5
