    摘要： The invention relates to an embedder for embedding a watermark in a representation of input information, comprising an information inserter that is designed to provide the representation of input information with the watermark and additional information that is to be inserted in order to obtain a representation of input information that is provided with a watermark and the additional information. The additional information that is to be inserted comprises descriptive information describing the embedding of the watermark or watermarks in the representation of input information.

    摘要： A watermark generator for providing a watermark signal as a sequence of subsequent watermark coefficients based on a stream of subsequent stream values representing discrete valued data comprises a differential encoder. The differential encoder is configured to apply a phase rotation to a current stream value of the stream values representing the discrete valued data or to a current watermark symbol, the current watermark symbol corresponding to a current stream value of the stream values representing the discrete valued data, to obtain a current watermark coefficient of the watermark signal. The differential encoder is configured to derive a phase of a previous spectral coefficient of a watermarked signal which is a combination of the host signal and the watermark signal. The differential encoder is further configured to provide the watermark signal such that a phase angle of the phase rotation applied to the current stream value or the current watermark symbol is dependent on the phase of the previous spectral coefficient of the watermarked signal.

    摘要： An apparatus (10) for determining a position for an object (5) in relation to a presentation of an image (3) that is to be presented comprises a position pattern generator (12) for generating a position pattern (13) which is divided into a multiplicity of pattern sections, wherein each of the pattern sections has a unique bit pattern comprising a multiplicity of bit patterns and wherein the bit patterns are Gray-coded in a generalized manner. The apparatus (10) also comprises a combination unit (14) for combining the position pattern (13) with the at least one image (3) that is to be presented and for providing a corresponding combined image, and an optical sensor (15) for optically sensing an image detail from the combined image, wherein the image detail correlates to the position of the object (5). In addition, the apparatus (10) comprises a filter (16) for extracting at least one bit pattern, which corresponds to a pattern section from the position pattern (13), from the image detail and for providing at least one corresponding extracted pattern section, and also a determination device for determining the position of the object (5) on the basis of the at least one extracted bit pattern. A method for determining the position of an object (5) is likewise disclosed.
