Effect of ROM data and slideshows on the bit rate calculation
If you add ROM data to your DVD as described in “Adding ROM content to the DVD” on
page 34 , you must reduce the disc size in the bit rate calculation to account for the ROM
content. For example, if the ROM content is 500 MB, the disc size available for DVD-Video
is:
36,096 Mbits – 4,194 Mbits = 31,902 Mbits
(500 MB = 500 x 2
20
x 8 bits = 4,194 Mbits)
Slideshows generally use very little disc space. However, if you create an OpenDVD disc or
you choose to archive the slideshow images, the original image files are archived in the
same location as ROM data. If you use uncompressed high-resolution images in your
slideshows, the original files could require a significant amount of space.
To account for slideshow image files, add up the sizes of all the files and subtract from the
disc space as shown above.
