Abstract
A system for presentation timeline synchronization across audio-video (AV) streams associated with a common event may include memory and a processor. The processor may be configured to receive metadata items from a user device during a live event, the metadata items corresponding to points-in-time marked by the user while being presented with an audio-video (AV) stream associated with the live event. The metadata items may include timing indicators that are indicative of the marked points-in-time relative to the start of the live event. The processor may be configured to provide to the user device with other AV streams associated with the live event that were available at one of the points-in-time marked by the user. The processor may be configured to provide the other AV streams to the user device beginning with a frame that corresponds to the one of the points-in-time marked by the user.
