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

The invention relates to a method for generating a marked data flow from an encoded data flow. According to said method, encoded multimedia information is contained in a first data flow section of the 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. The invention also relates to a method for inserting watermarks into the marked data flow, and devices for generating the marked data flow and for inserting watermarks into the marked data flow.
