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 the Players. Players will this feature enable 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 support Proof of Play. If either of these settings are reached by the 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.
As an example of file size, if a Player is logging impressions every 10 seconds for 24 hours then then CSV file size will be roughly 800kb's.
