ABSTRACT:
The invention relates to the synchronized playback of video and/or audio recordings in terminals of a communications network. A server stores recordings including timing markers, each of which indicates an internal position within the recording. The system comprises groups of user terminals, at least one channel being assigned to each group. A recording is transmitted to the terminals belonging to the same group and stored there. In response to a start command, the playback of the recording is started at each terminal. Status information indicating at least the playback position of the recording is maintained, and the playback is controlled by transmitting new status information to the terminals of the group. The playback status is changed at each terminal according to said new status information.
