Unifying conflicting media identifiers

A server for use in a system that receives primary content from a plurality of sources, and delivers content to a plurality of subscribers for further distribution to end users, the server comprising:

• processing circuitry configured to receive a message indicating that a content item is being transmitted to at least one end user by a first media station, the message including an alias identifier associated with the content item, and a station identifier associated with the first media station;
• processing circuitry configured to match the content item associated with the alias identifier to a primary content item associated with a master identifier;
• processing circuitry configured to determine a station override status associated with the first media station;
• and
• processing circuitry configured to provide enrichment data associated with the master identifier in accordance with the station override status.

A media delivery system that receives primary content from a plurality of sources, and delivers content to a plurality of subscribers for further distribution to end users, the media delivery system comprising:

• a server machine configured to implement a push-now-playing (PNP) service, the PNP service configured to:
• receive a PNP message indicating that a content item is being transmitted to at least one end user by a first subscriber, the PNP message including an alias identifier associated with the content item, and a station identifier associated with the first media station;
• match the content item associated with the alias identifier to a primary content item associated with a master identifier;
• the server machine further configured to determine a station override status associated with the first media station;
• and
• the PNP service further configured to providing enrichment data associated with the master identifier in accordance with the station override status.
