摘要：
The present invention relates to digital watermarking. In a preferred embodiment, a multi-channel media signal is embedded with first and second digital watermark components. The first component is embedded in a first of the channels and a second component is embedded in a second of the channels. The second component is registered with the first component so as to reduce visible attributes that are attributable to the first component.
