To ensure that the Proof of Play data transfer between your players and Signagelive is kept low, only the minimum of data is sent to and from players. Players with this feature enabled will upload their logs at set intervals, which is defined by the network that they are registered upon. At the moment this interval is set by default to be every 24 hours.
There is also a maximum file size and minimum disk space setting for each player type that supports Proof of Play. If either of these settings are reached by a player then the corresponding Proof of Play log is uploaded to our server straight away. These logs are checked each and every time an impression is logged.
Please refer to the following information to gain a better understanding of how impressions over time can impact the Proof of Play data file sizes:
