WM signal generation device, wm signal generation method, computer-executable program for executing wm signal generation method and computer readable recording medium ON WHICH the program IS RECORDED, digital watermarking device, and digital TV set including the digital watermarking device

摘要

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.
