A live media content switching system inserts, based on one or more events in a first live input stream manifest, information related to a plurality of first media segments and the one or more events from the first live input stream manifest into a first disparate live media output stream manifest, based on a programming schedule. Based on a switching between a first live input stream indicated in the first live input stream manifest from a first regional network and a second live input stream indicated in a second live input stream manifest from a second regional network at scheduled time stamps, an updated first disparate live media output stream manifest is generated. The first live input stream and the second live input stream are switched based on a type of the one or more events.
