MediaTailor, which offers channel assembly and personalized ad insertion, incorporated support for LL-HLS utilizing HLS Interstitials, allowing video providers to insert advertisements into live streaming content without sacrificing the reduced latency viewers expect. This design references ads as separate cacheable playlists, which helps sustain low latency at scale by cutting ad decision server calls from the manifest request path.
The solution has been independently proven in production during large-scale sporting events with millions of viewers and is suitable for applications requiring minimal latency such as live sports, news, betting, and interactive formats. AWS offers Low-Latency HLS ad insertion in all Regions where MediaTailor operates.
