Method and Device for Generating a Marked Data Flow, Method and Device for Inserting a Watermark Into a Marked Data Flow, and Marked Data Flow

摘要

A method generates a marked data flow from an encoded data flow; at least one first data flow section of the encoded data flow is marked as a marked data flow section; and the marking of the marked data flow section indicates that the marked data flow section is suitable to be mixed with a watermark. A method inserts watermarks into the marked data flow, and devices generate the marked data flow and insert watermarks into the marked data flow.
