Abstract: Some implementations include methods for replacing advertisements that have been inserted into a manifest associated with live streaming and may include receiving a request for a manifest from a player to enable a user to watch a live stream of an event. The request may be received at a first time when the live stream is already in progress. The manifest may be generated to include content fragments associated with the live event and advertisements based on first set of selection criteria. The manifest may be sent to the player to enable the user to watch the live stream. A seek back request may be received from the player to enable the user to watch the live stream at a second time earlier than the first time. The manifest may be updated to replace at least one advertisement with a replacement advertisement selected based on second set of selection criteria.
