Digital signage software used for advertising requires very specific features.
1. Ability to predefine a number of impressions that must be strictly enforced, whatever the number of ads to display.
2. Ads must be spaced out at regular intervals in order to maximise audience exposure.
3. Content tags and campaigns: End users must be able to create and manage tags (metadata) that are assigned to each player and ad content.
4. Secure proof of playback reports must be available so ad network operators and advertisers can validate what was actually shown on each player.
