To enable Macrovision APS
1 Open the Disc Inspector by selecting the disc in the Outline tab or clicking an empty area
in the Graphical tab.
2 Click the Region/Copyright tab.
3 Select the Copyright Management checkbox.
4 Choose No Copy Permitted from the Copy Generation pop-up menu.
5 Choose the type of Macrovision protection to use (Type 1, Type 2, or Type 3) from the
Macrovision pop-up menu.
Note: The Format for CSS checkbox has no bearing on the Macrovision setting.
The Macrovision coding is applied to the entire disc. Once you have chosen No Copy
Permitted from the Copy Generation pop-up menu, you can also apply or change
Macrovision coding on specific tracks and markers using the Other tab in each track’s
Inspector and the General tab in each marker’s Inspector.
Note: If you configure Macrovision on a track or marker before you configure it for the
disc in the Disc Inspector, the settings in the Disc Inspector automatically update to match
the track or marker settings.
Three Macrovision types are supported by the DVD-Video specification:
• Type 1: Uses the Automatic Gain Control (AGC) process. The AGC process places pulses
in the vertical interval of the video stream that televisions do not detect. When a copy
is attempted, these pulses confuse a VCR’s AGC circuitry, causing copies to exhibit
characteristics such as dim and noisy pictures, loss of color, loss of video, and picture
tearing.
• Type 2: Uses both the AGC process and a two-line colorstripe. The colorstripe process,
which is only effective with NTSC video streams, consists of changes to colorburst
information that are transparent on original viewing, but that produce horizontal lines
across the picture when playing an unauthorized copy. The 2-line version of colorstripe
has bands of altered chrominance 2 horizontal lines long.
• Type 3: Uses both the AGC process and a four-line colorstripe. The 4-line version of the
colorstripe process has bands of altered chrominance 4 horizontal lines long. This is
also only effective with NTSC video streams.
About Jacket Pictures

allow a DVD player to display a graphic representing a DVD. Jacket pictures are most
commonly displayed on multi-disc players.
