DOOHAd is designed to be a flexible scheduling system you can use to automatically create playlists for a number of different Out of Home scenarios.

At it's heart, one (or more) playlists are created by the system for your screens (interactive kiosks or digital signage screens) to download and play. Content for these playlists can be managed by teams of people, via invites to clients or by third parties. The content can be automatically checked to ensure it meets with a screen's requirements (resolution, orientation and length), and will automatically get transcoded to a compatible format if required. Content uploaded by outside organisations requires approval before use, whereas content by your team can be auto-approved for streamlined operation.

How?

It all starts with Campaign Types. Here you can setup all of the different output styles you are using and selling. A full-screen Digital Billboard will typically be 1080pixels x 1920pixels - a 16:9 aspect ratio. However you may find you have a mixture of screens in your portfolio - or even systems (typically interactive ones) which show advertising as only a small portion of the actual screen output (think advertising banners).

Here also, you can decide if you want to have freedom over the playlists - effectively selling the ability to advertise without restraint (no guaranteed number of impressions) - or if you want a fixed playlist length so that an advertiser can understand they will get a guaranteed number of impressions for the period the campaign operates.

To clarify this:

Using an unconstrained playlist... If for example you have a playlist with 2 items in it of 10 seconds each. This makes the content play 3 times in a minute. In an hour, this plays for (60 x 3) 180 times. In 24 hours, this plays each advert (24 x 60 x 3) = 4320 times. And if both adverts are to run for 10 days, they will shown (10 x 24 x 60 x 3) = 43,200 times.

Now, if another 10-second advert is added to this playlist, each advert will now only play **twice ****a minute. This means that all of the adverts will only play 28,800 times in their 10 day campaigns.

(note: the above assumes all campaigns start/stop on the same days, all players operate 24/7 and playout has no interruptions or delay between one item playing and the next - hence why most DOOH ad sales are an 'expected' number of impressions).

Obviously if an advertiser is expecting their adverts to play a guaranteed number of times (number of impressions), then we need to stop this number changing when other adverts are added/removed from the playlist. This is where the constrained playlists come in useful.

In the case of a constrained Campaign Type, a fixed number of saleable Inventory Items are pre-defined, together with a fixed slot length. This way, there will always be the same number of items in the playlist - no more and no less.
