Abstract
One or more servers in an IP network receive, from a user device, a selection of live streaming content and assemble an index file including links to chunks of the selected live streaming content and links to advertising files for insertion within the selected live streaming content. The one or more severs send, to the user device, a link to the index file associated with the selected live streaming content and receive, from the user device, a streaming request for the selected live streaming content. The one or more servers send, to the user device, the index file including the links to chunks of the selected live streaming content and the links to advertising files for insertion within the selected live streaming content. The user device may use the links to combine the chunks of the selected live streaming content and the advertising files into a single linear presentation. A standards-based client for the user device is used with the server side implementation. Multiple groupings of index files, based on various location and business criteria, allow for reduction in media stream creation, and granularity of addressing each subscriber.
