Abstract
Master computing device and method for synchronizing display of a digital content (for example a digital signage content) on the master computing device and on one or more slave computing device. The master device transmits a synchronization request, comprising a digital content identifier for identifying the digital content, to the slave device(s). The master device determines a number of negative responses received from the slave device(s) in response to the synchronization request. Each negative response is indicative of one among the slave device(s) not being capable of displaying the digital content. The master device transmits a new synchronization request to the slave computing device(s) if the number of received negative responses reaches a threshold. The master computing device transmits a display command to the slave device(s) for displaying the digital content on their respective display(s) if the number of received negative responses does not reach the threshold.
