Abstract: Digital display method for displaying digital contents in a coordinated manner by digital display devices (2) belonging to a group (G), the digital contents being defined in playlists stored by each of the digital display devices, the method including: electing 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.

Abstract: A digital display device comprising: a digital screen; a first receiver able to receive a first content via a first communication channel; a second receiver able to receive a message via a second communication channel; a first player able to play on the digital screen the first content received via the first communication channel; a switch configured for deactivating playing of the first content by the first player, upon receiving the message via the second receiver.

Abstract: Method implemented by at least one server which controls the display of digital content items by digital display devices, comprising: a) generating playlists, each playlist being intended to be played by one or more of said digital display devices, the generation of a playlist according to a display campaign comprising: a2) calculating a minimum number of occurrences of playing each content item that allows compliance with the share of total playing time allocated to each content item; a3) reducing the number of occurrences of at least one content item; a4) inserting identifiers of digital content items to be played into the list; e) sending at least one of said playlists to one or more of said digital display devices for which at least one of said playlists is intended.

Abstract: A sanitary facility comprising: a waste detection device; a central unit receiving information from the waste detection device, and determining in which preset zone(s) of the floor the waste is located; and a washing device for the floor (7), the washing device comprising: at least one nozzle able to spray a fluid; means for rotating the at least one nozzle; and means for detection of angular positions of the at least one nozzle, the rotating means being driven by the central unit for selectively washing the preset zones of the floor on which the waste is present.

Abstract: A display method comprising: generating by a platform for generating playlists, playlists intended for digital display devices, the playlists having free time slots; synchronizing digital display devices with the playlist generation platform; for each free time slot of each playlist, corresponding to a digital display device, sending a content request by the platform for generating playlists, to a programmatic platform for selling advertising space, the programmatic platform being adapted to emit a corresponding bid and to send back to the platform for generating playlists, information corresponding to content having won the bid; informing of the content having won the bid, by said platform for generating playlists, the at least one digital display device corresponding to the free time slot.
