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

Device, program and storage medium can generate improved tolerance and quality WM signals and the digital television for digital watermarking, including the function of digital watermark. Device (10) digitally be embedded in for generating a WM signal and is used as watermark to be embedded into real time content include reception device (12), for receiving real time content; Input buffer (14), wherein real-time content is to keep; It is corresponding with the predicted intensity of real time content from segmentation real time content to generate WM signals; And output buffer (18), the WM signals for that will generate. Generation means include the WM signals of prediction meanss (16) predicted intensity; Controller (20) is used to control embediment and uses message to being embedded in the real time content for being embedded into as watermark division; With input unit (22), WM signals are exported for generating.
