The Rise of Server-Side Ad Insertion

If you’re in the OTT or VOD space, you’ve likely heard about Server-Side Ad Insertion (SSAI) — one of the most effective ways to monetize video content without frustrating your audience.

Unlike traditional ad delivery methods, SSAI provides a more seamless and user-friendly experience. It helps you insert ads into your streams smoothly, without buffering, black screens, or ad blockers getting in the way.

What is Server-Side Ad Insertion (SSAI)?

Server-Side Ad Insertion (also known as dynamic ad insertion) is the process of stitching ads directly into the video stream on the server side, instead of on the viewer’s device.

In simpler terms:

• The ads are blended into the video before it reaches the viewer.

• The viewer experiences the ads as part of the stream, just like regular content.

• There are no separate ad calls made by the player on the device, reducing ad-blocker effectiveness.

How Does SSAI Work?

Step 1: Content + Ad Request

When a viewer starts a video, the server sends a request for ads from an ad server or SSP (Supply-Side Platform).

Step 2: Ad Stitching

The ad creatives are stitched directly into the video content stream on the server.

Step 3: Smooth Playback

The stitched stream — now containing both the content and ads — is delivered to the viewer without noticeable transitions or buffering.

Since the ads are already part of the video stream, there’s:

• No need for separate ad loading

• Less chance of buffering or errors

• Higher compatibility across devices
