A Digital display method for displaying digital contents in a coordinated manner by digital display devices belonging to a group, the digital contents being defined in playlists stored by each of the digital display devices, the method including:
- electing by the digital display devices of the group, a leader among said digital display devices of the group, using a consensus algorithm;
- determining from synchronization messages sent by the leader to the other digital display devices of the group, a display starting time for each digital content defined by the playlist of each device of digital display of the group.
A digital display system comprising digital display devices, at least some of said digital display devices belonging to a group, the digital contents being defined in playlists memorized by each of the digital display devices, the digital display devices of the group being adapted to:
- elect a leader among said digital display devices of the group, using a consensus algorithm, said leader being adapted to send synchronization messages to the other digital display devices of the group;
- determine from the synchronization messages, a display starting time for each digital content defined by the playlist of each digital display device of the group.
