Abstract: An architecture is presented that synchronizes digital television content with IP network content. A content management system is provided that comprises a computing system that includes an input component and an application component. The input component of the computing system receives digital television content of a broadcast network. The application component receives IP network content of an IP network. The application component then synchronizes the IP network content and the digital television content via DSM-CC stream events. The DSM-CC stream events are markers that comprise an event identifier and a time reference. Based on the event identifier and the time reference, the broadcasted digital television content can be synchronized with the IP network content to deliver additional content media and commercials tailored to specific groups of viewers based on demographics, geography and/or individual profiles.
