# Trigger-based Blackouts

You can use cue points to trigger a blackout during which your stream will play a **silent audio file**. End the blackout by sending another cue point. This is useful when you need to silence your stream for a specific period of time, such as during a sporting event blackout. Ideally, you should send this cue point at regular intervals, to protect against the unlikely event of a complete stream restart.

If the silent audio file is unavailable for some reason, the listener is disconnected. (This is a fallback measure only, and is largely moot since listeners will likely disconnect themselves when they connect to a silent stream.)

| Attribute | Description | Type | Required |
| --- | --- | --- | --- |
| **blackout_state** | Blackout period state. Valid values: - **start** - **end** | String | **Yes** |

Set the `blackout_state` attribute to `start` when the blackout period begins. Set the `blackout_state` attribute to `end` when the blackout period ends.

> [!NOTE]
> **Ad injection** for your mounts must be enabled in order to trigger a blackout via cue points. If it is not currently enabled and you would like to use ad injection, please [contact Customer Support](/user/docs/contact-support). Note that ad injection is a paid service.
