Short answer
Server-side ad insertion (SSAI) is a method of stitching ads directly into a video or audio stream on the server, so content and ads play back as one continuous stream. Also called dynamic ad insertion, it reduces buffering and makes ads harder to block. It is widely used in connected TV, live streaming and podcasts.
