What are Menu and
Navigation?
Interactivity on a DVD-Video disc is provided
as menus, which allow the user to select particular sequences or functions
. Each menu comprises a still image or video loop as background plus up to
36 rectangular buttons, which use subpictures for highlighting. Different
versions of the menu are required for widescreen, letterbox, and pan &
scan mode. In this case only 12 buttons are available for each, making 36
in total. The user selects buttons (instead of moving a cursor) and use
the Up/Down/Left/Right arrow keys on a remote control. The three available
subpicture colors (the fourth is transparent) can be used to indicate what
state the button is in: unselected, highlighted or selected. This provides
the necessary feedback to the user. This user interface may be a bit
cumbersome but generally makes it easier to use from a remote control
device.
By using DVD-CLONER, you can select
whether you will save the movies of DVDs only, without keeping menus or
not. |
