Abstract
A system is provided for enabling correlating timeline information between a first media stream and a second media stream, with the first media stream and the second media stream being both associated with a common play-out timeline. The system comprises at least two content monitors, each arranged for providing a persistent identification of one or more media samples of a media stream. The system further comprises a correlation subsystem arranged for receiving a first persistent identification related in time with a second persistent identification, receiving a first timestamp value of the first media stream related in time with a second timestamp value of the second media stream, matching the first persistent identification to a first play-out time on the common play-out timeline and the second persistent identification to a second play-out time, and generating correlation information based on a comparison of the first play-out time with the second play-out time for enabling correlating the first timestamp value with the second timestamp value and thereby correlating the first timeline information with the second timeline information.
