Abstract
An apparatus including a transformer for transforming transform domain data into time domain data and a combiner for receiving material and combining said time domain data with said material to form data embedded material. Hence, the material is not subject any transformation at all.
Claims29
An apparatus comprising:
- an inverse transformer configured to perform an inverse transformation of watermark data from a transform domain into watermark data in a time domain, wherein said transform domain is a domain other than the time domain, the transform domain watermark data comprising a plurality of transform domain coefficients and the time domain watermark data comprising a plurality of time domain samples which represent the watermark data in the time domain;
- and
- a combiner configured to receive material into which no watermark data has been embedded, the material being in the time domain, the material comprising a plurality of time domain samples, and to combine the samples of said time domain watermark data with the time domain samples of said material in the time domain to form watermark data embedded material.
A method comprising the steps of:
- inverse transforming watermark data from a transform domain into watermark data in the time domain, wherein said transform domain is other than the time domain, the transform domain watermark data comprising a plurality of transform domain coefficients and the time domain watermark data comprising a plurality of time domain samples which represent the watermark data in the time domain;
- receiving material into which no watermark data has been embedded, the material being in the time domain, and the material comprising a plurality of time domain samples;
- and
- combining the samples of said time domain watermark data with the time domain samples of material to form watermark data embedded material.
