1. A method comprising:
- analyzing a plurality of frame subsets of a content signal by a processor to detect existence of an isolated change in a measurable parameter within a plurality of frames of a content signal, a particular frame subset including a plurality of subset frames;
designating a change in measurable parameter (CMP) frame and a comparison frame among the plurality of subset frames by the processor based on the existence of the isolated change, the CMP frame having the isolated change in the measurable parameter;
selecting a plurality of selected frames of the content signal at a frame offset of zero or more frames from the CMP frame by the processor as a particular frameset of a plurality of framesets;
designating one or more line designation patterns for the plurality of frames of the plurality of framesets by the processor, a particular line designation pattern of the one or more line designation patterns including a designation of a particular content line of a plurality of content lines of a particular field as a normal line or an inverse, the particular field being of a particular frame of the plurality of frames; and
modulating the plurality of content lines of the particular field of at least two of the plurality of selected framesets by the processor in accordance with the one or more line designation patterns toembed a rights assertion mark within an active portion the content signal.

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.

14. A computer-readable medium comprising computer executable instructions, which when executed by one or more processors, cause the one or more processors to perform the following operations:
-
analyze a plurality of frame subsets of a content signal to detect existence of an isolated change in a measurable parameter within a plurality of frames of a content signal, a particular frame subset including a plurality of subset frames; designate a change in measurable parameter (CMP) frame and a comparison frame among the plurality of subset frames based on the existence of the isolated change, the CMP frame having the isolated change in the measurable parameter; select a plurality of selected frames of the content signal at a frame offset of zero or more frames from the CMP frame as a particular frameset of a plurality of framesets; designate one or more line designation patterns for the plurality of frames of the plurality of framesets by a processor, a particular line designation pattern of the one or more line designation patterns including a designation of a particular content line of a plurality of content lines of a particular field as a normal line or an inverse, the particular field being of a particular frame of the plurality of frames; and modulate the plurality of content lines of the particular field of at least two of the plurality of selected framesets in accordance with the one or more line designation patterns to embed a rights assertion mark within an active portion the content signal.
