An example method includes detecting over a particular time-period and at a periodic interval, match data indicating whether reference fingerprints representing content transmitted by a non-local content-distribution system on a particular channel matches query fingerprints representing content received by a content-presentation device on the particular channel. The method also includes based on the match data, identifying three time-periods within the particular time-period, the middle of which being a time-period (i) in which there is a threshold consistent lack of matching for a threshold duration and (ii) that corresponds to a detected portion of the received content that serves as a placeholder for local content to be inserted by a local content-distribution system. The method also includes based on the three identified time-periods, detecting, that the local content-distribution system inserted local content into the content received on the particular channel in connection with the detected portion, and responsively performing an action.

An example method includes determining, over a particular time-period and at a periodic interval, a viewer count of content-presentation devices receiving content on a channel from a non-local content-distribution system and, based on the viewer count, identifying, within the particular time-period: (i) a first time-period having a threshold consistent viewer count for a first threshold duration, (ii) a second time-period where there is a drop in the viewer count by a threshold amount and the drop lasts for a second threshold duration, and (iii) a third time-period where the viewer count returns to an amount within a threshold range of the threshold consistent viewer count for a third threshold duration. The method also includes based on the identified time-periods, detecting a portion of the content that serves as a placeholder for local content to be inserted by a local content-distribution system, and performing an action associated with the detected portion.
