Connecting a Second Screen

This section describes how to connect a second screen to the GCS.

Introduction

The second screen function streams the video feed to a local device via an RTSP-based video stream from the GCS.

The second screen connects to the GCS, not directly to the UAV, to avoid doubling the UAV's bandwidth usage.

The video feed displayed on the second screen is the direct feed from the camera.

Using a WiFi hotspot

A second device can connect to the same network if your GCS is connected to a WiFi network or hotspot.

To stream the video feed locally to a second screen, you need the following:

• The IP address of the GCS.

• VLC Media Player (recommended software) for viewing the video stream on the second screen device. The VLC Media Player is cross-platform compatible and can be installed on many devices.

• The GCS and the second screen device need to be connected to the same Wi-Fi network or hotspot.

• The DeltaQuad Evo and the GCS need to be powered on and connected.

When ground-testing the video feed with an infrared-capable camera it is important to provide active cooling. We recommend a USB fan pointed directly towards the camera.

1. Once the GCS is connected to the Wi-Fi network or hotspot, you can determine the Wi-Fi IP address assigned to the GCS by opening the Evo Control Panel.

1. Here you will find the Wi-Fi IP address which shows the values for the IP address assigned by the Wi-Fi network or hotspot. The value required is the sequence of 4 numbers separated by a dot, in our example: 192.168.2.68

1. Make sure that the second screen device is connected to the same Wi-Fi network or hotspot as the GCS and open the VLC Media Player.

The VLC user interface might look different depending on the platform in use.

1. Go to Media and open the Stream... function.

1. Go to the Network tab.

1. In the network URL field enter the following address:

rtsp://[IP-ADDRESS]:8553/stream1

In our example, it is rtsp://192.168.2.68:8553/stream1.

1. Check Show more options and set the value for Caching to 100ms. Click on Stream in the lower right corner of the window.

1. Click Next in the Source window.

1. Click Next in the Destination Setup window.

1. Click Next in the Transcoding Options window.

1. Click Stream in the Option Setup window.

1. After a few seconds, the video feed should appear in the VLC Media Player.
