Abstract: A time difference between an occurrence of a first event and an occurrence of a second event is estimated. A first time marker indicating the occurrence of the first event and a second time marker indicating the occurrence of the second event are received, wherein at least one event is one of playing a media frame or receiving a beacon. A plurality of delayed versions of the first time marker are provided, each being delayed by a different amount of delay to the other delayed versions. Each of the delayed versions of the first time marker are compared with the second time marker to identify which of the delayed versions of the first time marker is the closest temporally matching time marker to the second time marker. The time difference between the first and second time markers is estimated in dependence on the identified delayed version.
