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.
