S4M Asset Scheduling

We have implemented a custom S4M asset scheduling process that reads data from the S4M data source and applies it to an Asset Schedule in Chameleon.

The main pieces are

  1. Read S4M data

  2. Create required assets

  3. Schedule assets repeatedly and evenly through a 24 hour period.

    1. but not during blackouts (scheduled in Flow)

S4M Data Source

The S4M data is stored in a SQL Server Database.

There are a couple tables that provide the data:

  • [COP_Uci].[uci].[available_s4m_spot_media]

  • [S4M_Schedule].[s4m].[dlevent]

We have built an ASP.Net Core minimal web API to access this data. This app is running in IIS. It has it’s own Application Pool and an Application in the Default Web Site. By using this type of access we can either pull the data live as json or use BLADE Runner to pull the data and post it somewhere else for access.

The published code is simply copied into the website folder to update it.

API Endpoints

Example endpoint to get the BC1 station’s data for Jan 6, 2023:

http://localhost/S4M/schedule/event/BC1?startDate=2023-01-06

To get to the details for a material:

http://localhost/S4M/material/00032512

All materials in Ad Zones

http://localhost/s4m/material/

False pulls data from the alt Url

Alternate Url

Alternate location where a data file has been made available to use instead - same json format as the live URL (saved output)

Alternate Material Url

Processing Steps

  1. Make a connection to the Chameleon database.

  2. Pull the S4M data for the given date

  3. Find the given content group, channel, and media bin items each by name

  4. Find or create assets based on the S4M Id

    1. Looks for an asset whose name matches the S4M Id in the given content group

    2. If not found

      1. Creates a new asset with a template named Ad Zone 1-4 based on the S4M data in the given project (if it can find it)

      2. Attaches the media with the name of the S4M Id to the media.media field (if it can find it)

  5. Reads the blackout schedule for the channel

  6. Calculates the total blackout time

  7. Determines the amount of time between assets that is left

  8. Loops through all the S4M assets, evenly adding each to the schedule in turn over the 24 hours minus the blackout times
