# Ross Video Server (Tria)

> Play clips from a Ross Tria video server — cue, play, stop and eject per channel, seek and jog, set repeat mode, and select an ISO camera angle.

The **Tria** device controls [Ross Video Tria](https://www.rossvideo.com/) video servers, so a rundown item can cue a clip on a channel and roll it exactly when the item goes on air.

## Connection

Provide the server's **host** and **TCP port**.

## Commands

| Command | What it does                                                             |
| ------- | ------------------------------------------------------------------------ |
| Cue     | Loads a clip into a channel without playing it, optionally at a timecode |
| Play    | Plays the loaded clip, or loads and plays one when a clip is supplied    |
| Stop    | Stops the clip playing in a channel                                      |
| Eject   | Unloads the clip in a channel                                            |
| Go to   | Seeks to a timecode in the loaded clip                                   |
| Jog     | Jogs the loaded clip by a number of frames, forwards or backwards        |
| Loop    | Sets the repeat mode for a channel                                       |
| Angle   | Selects the ISO camera angle for the loaded clip                         |

Every command targets a **channel**, so one configured server can drive all of its outputs from different rules.

<Tip>
  Cue on the rundown item's cue and play on its take. The clip is already loaded when the item goes on air, so playback starts without the load delay.

## State and triggers

The device reports its connection state and raises a trigger when the connection changes.
