Abstract
A system for delivering digital content to user devices. The system includes a content delivery server for establishing respective sessions with the user devices and for delivering streams of content to the user devices during the sessions according to a streaming protocol. An asset server is communicatively coupled to the content delivery server through an asset protocol for maintaining an asset scheduling table including asset entries, each asset entry including an asset identifier identifying a given asset in association with a starting time parameter, user identifiers identifying at least one target user device, and a set of session identifiers each identifying a session established with a target user device identified by the user identifiers. The content delivery server inserts, for each asset entry in the asset scheduling table, and for each session identified by a session identifier in the asset entry, the asset identified by the asset identifier of the asset entry into the stream of content delivered during the session, at a predefined insertion time.
