What is AVOD?

Advertising-based video on demand, or AVOD, provides programming whenever viewers request it and funds access wholly or partly through advertising. Ads may appear before, during, or after the content.

How AVOD works

AVOD is a distribution and revenue model layered over on-demand playback rather than a media codec or streaming protocol. A session must combine requested programming with selected ad opportunities, tracking, policy, and entitlement decisions. Ads can be stitched into the stream by the service or scheduled separately by the player, with different implications for seeking and measurement. Packaging workflows preserve cue points and create compatible renditions for both content and creatives.

Key facts

  1. Ad decisioning and media delivery are separate concerns: a decision service selects a creative, while the player or packager must still present compatible encoded segments.
  2. Server-side insertion can make program and advertising appear as one stream, but accurate reporting still depends on event signaling and cannot be inferred from file delivery alone.
  3. Creative duration, codec, resolution, audio layout, and segment boundaries need alignment with the program path; mismatches can cause discontinuities or playback failure.

When AVOD matters

An AVOD service must coordinate playback with ad selection, insertion markers, and measurement. Client-side insertion is simpler to separate, while server-side insertion can reduce visible transitions.
