# Dolby OptiView Ads Introduction

OptiView Ads is an ad insertion service for LIVE content (VOD support coming soon), utilizing Server-Guided Ad Insertion (SGAI) as well as Server-Side Ad Insertion (SSAI). On these pages, you'll learn how to get started with OptiView Ads, model your live streams, schedule ad breaks, and configure the OptiView Ads SDK — the recommended integration approach.

By logically redistributing responsibilities in the advertisement workflow, OptiView Ads:

* Creates a seamless viewer experience across platforms.
* Simplifies the workflow by reducing complexity, which results in easier implementation and lower operational risk.
* Introduces innovative ad formats, creating more diverse and less intrusive ad opportunities.
* Maximizes workflow efficiency by reducing prefetching and over-allocation of inventory.
* Enables more relevant ads through a high degree of personalization.

OptiView Ads models each live stream as a **channel**. A channel monitors one or more **origins**, detects or schedules **breaks**, and can use reusable **templates** for consistent ad experiences. It generates a **Break Manifest** for the OptiView Ads SDK to poll and render.

OptiView Ads supports both **Dynamic Ad Replacement (DAR)** — replacing ad breaks that are already present in your stream, detected through markers — and **Dynamic Ad Insertion (DAI)** — inserting new ad breaks that you schedule yourself.

OptiView Ads provides [integrations](https://docs-preview.optiview.dolby.com/pr-860/ads/integrations.md) with different ad servers for ad decisioning, transcoding, and serving, where [Google Ad Manager](https://docs-preview.optiview.dolby.com/pr-860/ads/integrations/google.md) is one of them.

For an end-to-end walkthrough, see [Getting started with OptiView Ads](https://docs-preview.optiview.dolby.com/pr-860/ads/getting-started.md). For the channel model, origins, breaks, and templates, see the [Channels concept](https://docs-preview.optiview.dolby.com/pr-860/ads/concepts/channels.md).

OptiView Ads enables innovative ad formats through the OptiView Ads SDK, providing new ways to monetize content in a less intrusive manner. The out-of-the-box [layouts](https://docs-preview.optiview.dolby.com/pr-860/ads/concepts/breaks.md#layouts) include:

* **Single**: Replaces the content with a full-screen advertisement.
* **Double Box**: Allows content to continue playing side-by-side with an advertisement and its companion background.
* **L-Shape Ad**: Plays the advertisement in the main window alongside a companion backdrop.
* **L-Shape Content**: Keeps the content playing in a scaled window alongside an ad backdrop.
* **Overlay**: Renders a non-linear advertisement on top of the content, which keeps playing.

Besides mid-roll breaks on the live timeline, breaks can also be [triggered by player events](https://docs-preview.optiview.dolby.com/pr-860/ads/concepts/breaks.md#event-based-triggers): **pre-roll** (when playback starts), **pause** (while the viewer is paused), and **post-roll** (when playback ends) — each with an optional delay.
