Abstract
A radio frequency (RF) receives a media broadcast including media items and embedded watermarks. A watermark detection module included in the RF receiver operates in a low-power state, during which the watermark detection module does not attempt to detect the embedded watermarks. The watermark detection circuitry is activated, thereby transitioning from the low-power state to an active state, in response to receiving an attention marker. during the active state the watermark detection circuitry attempts to detect the embedded watermarks in the media broadcast, and continues to do so until an indication that watermark detection is to be discontinued is received. In response to receiving the indication that the watermark detection is to be discontinued, the watermark detection module is again placed in the low-power state.
