Abstract: In some aspects, a method includes executing a streaming application configured to stream a media content item on a display of a television device, and receiving, from the streaming application, a request to generate a token. The method includes, in response to the request, obtaining a user identifier of a user account of a media platform, obtaining a plurality of signals used to select promoted content for the user account, generating the token to include the user identifier and the plurality of signals, and encrypting the token to generate an encrypted token. The encrypted token is configured to be included in a fetch request to retrieve a promoted content item, personalized to the user account, from a promoted content server associated with the media platform. The promoted content item is configured to be inserted into playback of the media content item by the streaming application.

Abstract: The present disclosure discusses systems and methods to mitigate traffic spikes in retrieving secondary content items for display in concurrently streamed content streams. The system can pre-fetch secondary content items for the upcoming secondary content slots. To retrieve an appropriate content item, the system can predict the length of the secondary content slot. The system can use the predicted length of the secondary content slot to distribute the traffic spike over a larger span of time to mitigate the spike.
