Abstract
A method for modulating mark (20) within content signal (18) that has frames, where each of the frames has content lines and one or more measurable parameters, where each of the content lines has pixels, and where each of the pixels has a value, the method comprising selecting framesets from among the frames of the content signal; modulating at least two of the framesets; and causing mark (20) to be present within content signal (18) by at least modulating at least two of the framesets.
Claims17
A method comprising:
- detecting on an encoder a scene change between a first frame and a second frame of a content signal;
- and
- modulating on the encoder a particular frame of the content signal based on detecting the scene change.
A computer readable storage medium comprising instructions, which when executed by a processor, cause the processor to:
- detect a scene change between a first frame and a second frame of a content signal;
- and
- modulate a particular frame of the content signal based on detecting the scene change.
A system comprising:
- an encoder to detect a scene change between a first frame and a second frame of a content signal and modulate a particular frame of the content signal based on detecting the scene change.
