Playing of first and second content streams delivered to respective first and second receiving devices is achieved following a seek command to one of the devices, by a synchronization controller which receives information identifying the segment in the first stream in which the start point is located, and the duration of time between the start point and the beginning of the next segment, and transmits a command to the second receiving device identifying a segment in a second stream, at which to resume play, and a time at which to start displaying, allowing the display controlled by the second receiving device to be resynchronized with the display controlled by the first receiving device after operation of the seek command on the first device.
