Zusammenfassung:	A method for preventing the copying of useable video content is disclosed. The method includes identifying the video signal content of a video signal that is suitable to be extracted, extracting video content from the video signal to transmit to a receiver, and replacing the extracted video content with marred video content in the video signal. The method further includes placing the extracted video content in a user data channel of a program stream for transmission to a receiver. In addition, the method includes transmitting portions of the video signal that contains the marred video content in a first channel of the program stream, and transmitting the extracted video content in a second channel of the program stream to the receiver. The signals transmitted in the program stream are synchronized for presentation in the display of the receiver. Only the program stream components that contain the marred video content may be recorded by a VCR or DVD recorder and the marred video is unsuitable for piracy or rebroadcast.
