    • The implementations of digital watermarks can be optimally suited to particular transmission, distribution and storage mediums given the nature of digitally-sampled audio, video and other multimedia works. Watermark application parameters can be adapted to the individual characteristics of a given digital sample stream. Watermark information can be either carried in individual samples or in relationships between multiple samples, such as in a waveform shape. More optimal models may be obtained to design watermark systems that are tamper-resistant given the number and breadth of existent digitized sample options with different frequency and time components. The highest quality of a given content signal may be maintained as it is mastered, with the watermark suitably hidden, taking into account usage of digital filters and error correction. The quality of the underlying content signals can be used to identify and highlight advantageous locations for the insertion of digital watermarks. The watermark is integrated as closely as possible to the content signal, at a maximum level to force degradation of the content signal when attempts are made to remove the watermarks.
    • 考虑到数字采样音频,视频和其他多媒体作品的性质,数字水印的实现可以最适合于特定的传输,分发和存储介质。 水印应用参数可以适应给定数字样本流的各个特征。 水印信息可以在单个样本中携带,也可以在多个样本之间的关系中携带,例如波形形状。 鉴于具有不同频率和时间分量的现有数字化样本选项的数量和广度,可以获得更好的模型来设计防篡改的水印系统。 考虑到数字滤波器的使用和误差校正,可以保持给定内容信号的最高质量,因为它被掌握,水印被适当地隐藏。 底层内容信号的质量可用于识别和突出显示用于插入数字水印的有利位置。 尽可能地将内容信号尽可能地集成到内容信号上,以在尝试去除水印时强制内容信号的劣化。
