Unsold time goes to the auction, not to house ads

CS Play publishes a screen to CS Context when all of the following hold:

• the player behind it is active and in the Active state;
• the screen is active and not archived;
• the screen has a GID;
• Available for programmatic is on for that screen.

That is the whole gate. Nothing else is enforced — a screen with no size, no address and no photos is published exactly like a complete one, and is simply never chosen. Turning Available for programmatic off drops the screen from the next inventory update.

It is also recommended to provide the Address, Side (A/B in Latin letters), and upload Images of the screen — inventory buyers see these when choosing placements.

OTS (Opportunity to See) is an audience measurement metric that estimates how many people had the opportunity to see an ad during playback. Unlike a simple ad play count (which records screen events), OTS measures actual audience presence near the screen.

On the Targeting tab, click Change targeting and select the frames this policy applies to. Each frame with an assigned policy reports OTS for every ad play on it.

Each ad play row on the Ad Play Statistics page includes an OTS column showing the audience count for that specific playback event.

The summary bar at the top displays the Total OTS — the sum of all audience contacts across filtered ad plays.

All export formats include the OTS value per ad play. The pivot-by-day format sums OTS values into daily totals.

If a screen does not have an audience measurement sensor installed, the OTS column shows no value for ad plays on that screen. Ad plays are still recorded normally — only the audience metric is absent.
