Client-side Ad Insertion (CSAI) is a method of dynamically inserting advertisements into video content on a client device. Unlike traditional Server-side Ad Insertion (SSAI), CSAI does not require ad decision making to occur on a server. Instead, the video player on the client device performs the ad insertion, either by retrieving an ad from a local cache or by making a request to an ad server.
CSAI can provide several advantages over SSAI, including better ad targeting, lower latency, and a more seamless user experience. It also offers greater control and flexibility for content providers, as they can choose which ads to show and when to show them, without relying on a third-party server.
However, there are also some challenges associated with CSAI, such as the need for a high-performance video player and the potential for ad blockers to interfere with the ad insertion process. Nevertheless, as more and more video content is consumed on client devices, CSAI is becoming an increasingly popular choice for ad insertion in the streaming video industry.
