Abstract: The “color stripe” process is well known in the video field for preventing copying by analog video tape recorders of video content, and operates by altering the phase of a portion of the video signal color burst. Here, a weakened version of the color stripe process is employed in a video signal whereby the color burst phase alterations are reduced or attenuated so there is no copy prevention effect on a typical video tape recorder. However the weakened color stripe process is still sufficient to be detectable by a suitable detector located in a compliant device, so the detected presence of the color stripe serves as an encoded indication of copy control or other content control for the video signal by the compliant device.
