Abstract: Master computing device and method for determining an actual number of impressions provided by a synchronized group of devices comprising the master and one or more slave computing device. The master device transmits a synchronization request to the slave device(s) and determines a number of negative responses received from the slave device(s) in response to the synchronization request. A negative response indicates that one slave device is not capable of displaying digital content. The master device determines a number of displays D capable of displaying digital content based on the number of negative responses received. The master device determines a metric representative of the actual number of impressions provided by the master device and the slave device(s). The metric is calculated based on the number of displays D. The master device transmits the metric to a server and the server calculates the actual number of impressions using the metric.

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.
