    Abstract: The disclosure provides for use of watermarking as a basis control abandonment of dynamic content modification. Upon detecting of the occurrence of a trigger event for causing a content presentation device to abandon a dynamic content modification with respect to a media stream being delivered to the content presentation device, an entity encodes into the media stream an abandonment-watermark interpretable by the content presentation device to cause the content presentation device to abandon the dynamic content modification. The content presentation device then detects the abandonment-watermark in the media stream being received by the content presentation device and in response to the abandonment-watermark, abandons the dynamic content modification.
