Unifying conflicting media identifiers
View Patent ↗A unified system of unique identifiers is used to match enrichment content with primary content being delivered by subscribers, e.g. broadcasters, in different markets, market segments, etc. Songs, video, advertisements, or other content from multiple different content publishers or databases, each of which may be assigned identifiers using different identification systems, are assigned a unified, unique identifier. The unique identifiers are also mapped to content identifiers used by subscribers. When subscribers provide primary content, for example by broadcasting the content to end users, enrichment content is matched to the unified, unique identifier associated with the content, and appropriate enrichment data and content are sent to the subscriber for distribution along with the primary content. If subscribers or content publishers change their own identifiers associated with content, the content can be un-matched and re-matched with the same or a different unique identifier.
1. A method 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 method comprising:
receiving 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;
matching the content item associated with the alias identifier to a primary content item associated with a master identifier;
determining a station override status associated with the first media station; and
providing enrichment data associated with the master identifier in accordance with the station override status.
2. The method of claim 1 , wherein the matching comprises:
comparing the alias identifier to a database of master identifiers.
3. The method of claim 1 , wherein the matching comprises:
comparing the content item associated with the alias identifier to the primary content item associated with the master identifier to identify changed primary content.
4. The method of claim 1 , further comprising:
associating enrichment data preferences with the master identifier.
5. The method of claim 4 , further comprising:
providing different enrichment data to different media stations based at least in part on enrichment data preferences associated with the different media stations.
6. The method of claim 1 , wherein the message is a raw PNP message, and wherein the method further comprises:
enhancing the PNP message to generate an enhanced PNP message comprising the enrichment data.
7. The method of claim 1 , wherein determining a station override status comprises:
determining whether the first station is included in an override list associated with a master station.
8. 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.
9. The server of claim 8 , wherein processing circuitry configured to match is further configured to:
compare the alias identifier to a database of master identifiers.
10. The server of claim 8 , wherein the processing circuitry configured to provide enrichment data is further configured to:
automatically provide the enrichment data if the override status is inactive.
11. The server of claim 8 , wherein, in response to the override status being active, the processing circuitry is further configured to:
conditionally provide the enrichment data if the station identifier is included in an override list as a slave station.
12. The server of claim 11 , wherein, in response to the override status being active, the processing circuitry is further configured to:
determine whether the station identifier belongs to a master station;
in response to a determination that the station identifier belongs to a master station:
update the station identifier originally included in the message to refer to a slave station associated with the master station to generate an updated message; and
process the updated message as if the updated message were the message originally received.
13. The server of claim 8 , further comprising:
associating enrichment data preferences with the master identifier.
14. The server of claim 10 , further comprising:
providing different enrichment data to different media stations based at least in part on enrichment data preferences associated with the different media stations.
15. The server of claim 8 , wherein the message is a raw PNP message, and wherein the server further comprises:
a PNP service configured to add the enrichment data to the raw PNP message to generate an enhanced PNP message.
16. 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 a 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.
17. The media delivery system of claim 16 , further comprising:
a unified numbering system (UNS) database; and wherein
the PNP service is configured to match by at least comparing the alias identifier to a master identifiers included in the UNS database.
18. The media delivery system of claim 16 , further comprising:
an enhancement database including a relational entry linking the enrichment data to the master identifier.
19. The media delivery system of claim 16 , further comprising:
an enrichment cache configured to store enrichment information for upcoming media items identified in the PNP message.
20. The media delivery system of claim 19 , wherein the PNP message is a raw PNP message, and the PNP service is further configured to:
enhance the PNP message using information stored in the enrichment cache.
