A process in which ads are inserted into video content by the viewer’s device after the content has been downloaded. This is different from server-side ad insertion (SSAI), where ads are inserted by a server before the content is delivered to the viewer’s device.
With CSAI, the ad insertion process happens on the client side, which can provide more flexibility and customization options for ad delivery. CSAI can also enable more interactive and engaging ad formats, such as interactive overlays and clickable ads.
CSAI is commonly used in digital video advertising across various platforms, such as desktop and mobile devices, as well as connected TV and over-the-top (OTT) streaming services.
