Use of watermarking to control abandonment of dynamic content modification
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.
1. A method comprising:
detecting 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, wherein detecting the trigger event comprises detecting a change of channel represented by the media stream being delivered to the content presentation device; and
responsive to detecting the occurrence of the trigger event, encoding an abandonment-watermark into the media stream being delivered to the content presentation device, wherein the abandonment-watermark is interpretable by the content presentation device to cause the content presentation device to abandon the dynamic content modification.
2. The method of claim 1 , wherein the method is carried out between a time when the content presentation device has received a directive to carry out the dynamic content modification and a time when the content presentation device would start applying the dynamic content modification, and wherein abandoning the dynamic content modification comprises forgoing the dynamic content modification.
3. The method of claim 1 , wherein the method is carried out while the content presentation device is applying the dynamic content modification, and wherein abandoning the dynamic content modification comprises discontinuing the dynamic content modification.
4. The method of claim 1 , wherein the dynamic content modification comprises dynamic ad insertion.
5. The method of claim 1 , wherein the dynamic content modification is responsive to fingerprint-based automatic content recognition.
6. The method of claim 1 , wherein the trigger event comprises a content-related trigger event.
7. The method of claim 1 , wherein detecting the trigger event is carried out by at least one entity involved with delivering the media stream to the content presentation device.
8. The method of claim 1 , wherein encoding the abandonment-watermark into the media stream is carried out by at least one entity involved with delivering the media stream to the content presentation device.
9. A method comprising:
detecting by a content presentation device an abandonment-watermark encoded in a media stream being received by the content presentation device, wherein the abandonment-watermark is encoded into the media stream responsive to detection of a change of channel represented by the media stream; and
responsive to detecting the abandonment-watermark encoded in the media stream, abandoning by the content presentation device a dynamic content modification of the media stream.
10. The method of claim 9 , wherein the method is carried out between a time when the content presentation device has received a directive to carry out the dynamic content modification and a time when the content presentation device would start applying the dynamic content modification, and wherein abandoning the dynamic content modification comprises forgoing the dynamic content modification.
11. The method of claim 9 , wherein the method is carried out while the content presentation device is applying the dynamic content modification, and wherein abandoning the dynamic content modification comprises discontinuing the dynamic content modification.
12. The method of claim 9 , wherein the dynamic content modification comprises dynamic ad insertion.
13. The method of claim 9 , wherein the dynamic content modification is responsive to fingerprint-based automatic content recognition.
14. The method of claim 9 , wherein detecting the abandonment-watermark encoded in the media stream being received by the content presentation device comprises detecting in the media stream a watermark and determining that the detected watermark encodes a value interpretable by the content presentation device to cause the content presentation device to abandon the dynamic content modification.
15. A system comprising:
a network communication interface;
a processing unit;
non-transitory data storage; and
program instructions stored in the non-transitory data storage and executable by the processing unit to carry out operations including:
detecting 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, wherein detecting the trigger event comprises detecting a change of channel represented by the media stream being delivered to the content presentation device, and
responsive to detecting the occurrence of the trigger event, encoding an abandonment-watermark into the media stream being delivered to the content presentation device, wherein the abandonment-watermark is interpretable by the content presentation device to cause the content presentation device to abandon the dynamic content modification.
16. The system of claim 15 , wherein the dynamic content modification comprises dynamic ad insertion.
