Systems and methods of managing online streaming content are contemplated in this application. A new data structure is discussed. The new data structure is useful for the organization and delivery of streaming content—especially live content. Systems and methods make it possible for a broadcast manager to determine when advertisements can be played during a live broadcast (e.g., during a time out in a basketball game). Episode containers (the new data structure) include different segments, including both video-segments and advertisement-segments, where segments can be used to broadcast video from different sources. This can be particularly useful for broadcasting of content online where advertisement videos can be hosted elsewhere from where the broadcast content is hosted, allowing users to seamlessly watch a program with advertisements without experiencing interruption when they are transitioned to an advertisement from the broadcast.
