Adding copy protection
If your project contains copyrighted material, you can use copy protection to protect the intellectual property rights of the material’s owner, as well as the rights of the disc’s publisher. The following copy protection schemes are available in DVDit Pro:
Copy Guard Management System (CGMS) limits the number of digital and analog copies that can be made.
Copy Scrambling System (CSS) encrypts the data to prevent digital copying.
Macrovision prevents analog copying.
CGMS is simply a “flag” that is added to the video stream when you burn a disc or write to DLT. However, many DVD players do not respect the CGMS flag. CSS and Macrovision are applied by the disc replicator. For that reason, you can only use CSS and Macrovision when writing to DLT.
You must obtain licensing rights to use Macrovision. For more information, contact your disc replicator or Macrovision (http://www.macrovision.com).
To add copy protection to the project:
- Choose File > Project Settings. The Project Settings dialog box appears.
- Click the Protection tab.
- Select the Enable Copy Protection checkbox.
- To use CGMS, choose an option from the CGMS list:
- To use CSS, choose No copies allowed from the CGMS list, then select the Format for CSS checkbox.
- To use Macrovision, choose No copies allowed from the CGMS list, then choose an option from the Macrovision list:
- Off: Provides no copy protection.
- Type 1: Prevents copying to analog videotape by using Automatic Gain Control (AGC). AGC confuses the video recorder by sending it a video signal that is stronger than it actually is, thereby creating a copy with very low levels and degraded quality. This option is compatible with both PAL and NTSC projects.
- Type 2: Imposes two-line color stripes on the recorded video signal in addition to using AGC. This option is only compatible with NTSC projects.
- Type 3: Imposes four-line color stripes on the recorded video signal in addition to using AGC. This option is only compatible with NTSC projects.
- Click the OK button.
Note: If you use copy protection, you cannot burn discs or write to disc images, and you cannot select the OpenDVD checkbox.
