Abstract: A device, a program, and a storage medium for generating improved tolerance and quality WM signals and for digital watermarking and a digital TV set including the digital watermarking function. A device (10) for generating a WM signal to be digitally embedded as a watermark into a real-time content comprises receiving means (12) for receiving a real-time content; an input buffer (14) in which the real-time content is held; generation means for generating a WM signal, corresponding to the predicted intensity of the real-time content, from the divided real-time content; and an output buffer (18) for holding the generated WM signal. The generation means comprises prediction means (16) for predicting the intensity of the WM signal; control means (20) for controlling embediment using a message to be embedded as a watermark into the divided real-time content; and means (22) for generating an output WM signal.

Abstract: An apparatus 10 for generating wartermark signals to be embedded as a digital watermark in real-time contents includes: input means 12 for inputting the real-time contents; an input buffer 14 for 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 buffer 18 for storing the generated wartermark signals to be outputted. The generation means is configured by including prediction means 16 for predicting intensities of the wartermark signals; control means 20 for controlling embedding by use of a message to be embedded as the digital watermark in the divided real-time contents; and means 22 for generating the wartermark signals to be outputted.
