Abstract
An apparatusfor generating wartermark signals to be embedded as a digital watermark in real-time contents includes: input meansfor inputting the real-time contents; an input bufferfor storing the real-time contents; generation means for generating wartermark signals corresponding to predicted intensities of the real-time contents from divided real-time contents; and an output bufferfor storing the generated wartermark signals to be outputted. The generation means is configured by including prediction meansfor predicting intensities of the wartermark signals; control meansfor controlling embedding by use of a message to be embedded as the digital watermark in the divided real-time contents; and meansfor generating the wartermark signals to be outputted.
