Content Protection (Windows Embedded CE 6.0)
1/6/2010
The DVD standard allows for two types of content protection.
- First, there is the Content Scrambling System (CSS). This is the data encryption process used to protect the contents of a DVD-Video disc from being copied digitally.
- Second, there is an analog protection system (APS). Once the player decodes the digital data stored on a DVD, the APS prevents the resulting analog video signal from being copied to videotape.
These content protection schemes are completely transparent to the DVD-Video API. All of the data and signal processing to implement these schemes takes place at a low level between the DVD drive, the DVD renderer, and internal portions of the DVD-Video API middleware that are inaccessible to the DVD-Video API interfaces.
