The invention relates to methods, devices, a system of devices and a signal where additional information is embedded in media content. The system includes a device (10) providing additional information (O, D) in a signal (y) having media content, comprising a first mapping unit (14) mapping the amplitude values of the media content onto first new values, and a multiplexing unit (16) inserting the additional information into the mapped media content. The system also includes a device (12) for receiving additional information (O, D) in a signal (y) having media content, comprising a demultiplexing unit (22) arranged to receive a signal including media content (xQ) the amplitude values of which have been mapped onto first new values together with additional embedded information (O, D), and remove the additional information from the mapped media content. The invention allows insertion of watermarks into media content such as audio.
Method of sending additional information in a signal (y) having media content comprising the steps of:
Method of receiving additional information in a signal having media content, comprising the steps of:
Device (10) providing additional information in a signal having media content, comprising:
Device (12) for receiving additional information (O, D) in a signal (y) having media content, comprising:
System of devices that can communicate with each other comprising:
Signal (y(n)) comprising media content (xQ(n)) with embedded additional information (O;D), where the amplitude values of the media content have been mapped onto first new values using a first mapping function (Cq), such that the additional information can be retrieved from the mapped media content.
