Abstract
Se provee un aparato (100) para proveer información de dirección en base a una señal de audio reproducida con una marca de agua incrustada. El aparato (100) comprende un procesador de señal (110), el cual está adaptado para procesar por lo menos dos señales de audio con marca de agua recibidas registradas por al menos dos receptores de audio en diferentes posiciones espaciales. El procesador de señal (110) está adaptado para procesar las señales de audio con marca de agua para obtener una información específica de receptor para cada señal de audio con marca de agua recibida. La información específica de receptor depende de las marcas de agua incrustadas, incrustadas en las señales de audio con marca de agua recibidas. El aparato comprende un proveedor de información de dirección (120) para proveer información de dirección en base a la información específica de receptor para cada señal de audio con marca de agua recibida.
