To detect at least one of a copy protection indicator and a redistribution control indicator in an analog video signal, the video format of the analog video signal is determined, e.g., by detecting the horizontal frequency and vertical frequency of the signal. Based at least on the determined video format, a region of the analog video signal that may contain the indicator is identified. The region may for example be one or more video lines in a vertical blanking interval. The region is examined until the indicator is detected. The indicator is confirmed, e.g., by re-detecting one or more occurrences of the same indicator value(s) later in the video signal. Once confirmed, the indicated copy protection and/or redistribution control may be effected by limiting either or both of copying and redistribution of the analog video signal. The indicator may for example be Copy Generation Management System Analog plus Redistribution Control (CGMS-A+RC) information.
