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. A method for detecting an encoded message within an encoded content signal. A pattern format is identified in at least one of the content segments. One or more encoded patterns are extracted from the one or more pattern formatted identified content segments. The one or more encoded patterns are decoded. The encoded message decoded from the encoded content signal is utilized.
