You can now configure ad break personalization for live streams with DVR-like time-shift windows using the Ad Break Suppression feature in AWS Elemental MediaTailor. For long-running events, or linear streams that have time-shift features enabled, viewers can start watching at the live edge, or at the start of the event or time-shift window. Using this feature, you can optimize the personalization of the time-shift window to increase the chance that only ad breaks that are viewed are personalized. For viewers joining live, you can choose to only insert personalized ads after the live point. For those joining from the start of the event, you can personalize all the ads within the manifest.
