Abstract: A method and system for encoding a content signal having one or more content segments. The one or more content segments of the content signal are identifying or obtained. One or more encoded patterns are superimposed or inserted in a segment portion of at least one of the one or more content segments by use of an insertion method that renders the one or more encoded patterns substantially invisible within the content signal.
