VAST is a contract between an ad-serving response and a video player. It describes creatives, tracking and additional demand hops, but it does not guarantee successful playback.

01

VAST response

A response may contain an inline creative or a wrapper that points to another VAST document. Each hop adds dependencies, tracking and potential latency.

  • Inline creative
  • Wrapper URI
  • Media files
  • Tracking events
02

Delivery environments

Web, mobile applications and connected TV devices have different player capabilities and inventory context. Environment policy should be explicit.

03

Nexus operating model

Nexus connects VAST service endpoints, tenant modules, delivery diagnostics and commercial visibility inside the same control plane.

Product accuracy

This guide describes Nexus product architecture and general AdTech operating concepts. Exact enforcement and integration behavior depends on the enabled revenue engine and agreed deployment configuration.
