    Abstract: In one embodiment, a first content item having synchronization information, the first content item being a first instance of a reference content item, a candidate content item, which is a second instance of the reference content item, having synchronization information, a synchronizing processor which determines a synchronization point between the first content item and the candidate content item, on the basis of matching the synchronization information of the first content item and the candidate content item, a timeline metadata transmitter, which transmits stored timeline metadata to a device on which the first content item is playing, the transmission of the stored timeline metadata beginning from the synchronization point, wherein the stored timeline metadata includes timeline metadata that has been previously aggregated from earlier broadcasts of instances of the reference content item. Related systems, apparatus, and methods are also described.
