Abstract
The invention relates to methods, devices and systems for reconfiguring a watermark detector. In many applications, it is useful to be able to change the operation of a watermark detector. Such changes may include changing how the watermark detector decodes or interprets a watermark embedded in a signal of a given media type, such as audio, video or still images.
