  • Method for processing an analog signal
    Publication number: 20060075238
    Abstract: The present invention relates to a method for processing an analog signal. The method involves hiding a digital watermark signal in the analog signal by combining the watermark signal with the analog signal (103). The watermark signal may be detected and extracted by a device (108) receiving the analog signal. The method includes embedding a key in the watermark signal, such that the key may be extracted and used by an encoding device (108) for encrypting digital content that is based on the analog signal. The invention also relates to an encoding device, which is arranged to perform such encryption.
