Macrovision

Macrovision is supported by the last device handling the video data before leaving the computer. In the case of a video port connection to a video card, the video card and the DVD navigator/splitter handle all Macrovision processing. The decoder is not involved.

If the decoder has an NTSC output, Macrovision encoding and Macrovision compliance is the responsibility of the decoder card. The KS_COPY_MACROVISION property indicates the level of Macrovision encoding on the media (levels 0 to 3). The decoder may use this information to enable or disable Macrovision encoding on the NTSC output.
