Systems and methods are described herein for synchronizing playback of media assets from multiple sources. For example, if a media asset is being delivered from two sources, a media guidance application may compare features in the media asset from the two sources and determine the amount of time that the two sources are out of synchronization. If the amount of time is greater than a threshold amount of time, the media guidance application may transmit supplemental content to a device receiving the media asset from the source that is ahead, such that the two sources are synchronized after the supplemental content is finished. If the amount of time is less than a threshold amount of time, the media guidance application may instruct the device receiving the media asset from the source that is ahead to pause the media asset until the two sources are synchronized.
