There are 3 stages of communication between a venue and Vistar’s ad server: the ad request from the venue, an ad response from Vistar, and the proof of play from the venue.
On average, those messages are the following sizes:
- Request - 900 B
- Response
- 1.25 KB if there is an ad to play
- 300 B if there is no ad to play, almost entirely headers
- Proof of Play - 400 - 800 B, depending on headers
For a venue requesting 1 :15s spot to Vistar in an 8 spot loop, operating 24 hours a day, and receiving an ad to play on every request, that would equate to 1.7 - 2 MB per day and 50-60 MB per month.
