Obscuring systems and methods are operable to obscure an intervening content segment that a user does not wish to view and/or listen to if that particular intervening content segment is again received at a later time. An exemplary embodiment includes at least a content segment obscuring system that samples the decoded stream of information corresponding to an initial portion of the intervening content segment, determines a vector signature of the sampled initial portion of the intervening content segment, wherein the vector signature corresponds to at least one location and an orientation of a vector in a multi-dimensional vector space, and compares the vector signature with a plurality of predefined reference vector signatures. In response to the vector signature substantially corresponding to at least one of the plurality of predefined reference vector signatures, the intervening content segment is obscured with replacement content.
