Jacket cover images (generally referred to as Jacket_P images) are used by some
DVD players to give a visual indication of what disc is available.
Jacket_P images are most often utilized by players that can hold more than
one DVD at a time (such as a Sony DVD jukebox).
Adding Jacket_P info to a disc is pretty simple. You will need to create one image that will be scaled to three different sizes (or, you could create a separate image for each size if you want to provide simplified graphics at lower resolutions). The three sizes are made available so that the DVD player can select the appropriate one for its display context (menus, details, etc.) The sizes are as follows:
Note that your menu aspect ratio should be 4:3 and that there are three underscores in a row in the filenames. As indicated by the filenames above, the images should be saved as MPEG2 encoded images. Once you've made the files, create a Jacket_P folder, store the images
in it, and include the folder as DVD-ROM data in your DSP project.
