Connecting a second screen

This section describes how to connect a second screen to your DeltaQuad Controller.

Introduction

The second screen function can stream the video feed to a local device.

The DeltaQuad Controller provides an RTSP-based video stream. The second screen will connect to the DeltaQuad Controller, not directly to the UAV. This is to prevent the UAV from having to use double the amount of bandwidth.

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

Using a WiFi hotspot

If your controller is connected to a 5GHz WiFi network or hotspot, a second device can connect to the same network. For information on how to connect the DeltaQuad Controller to a WiFi network or hotspot, please see the DeltaQuad Controller section.

In order to stream the video feed locally to a second screen you need:

• The "IP address" of the DeltaQuad Controller.

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

• In order to ground-test the setup and check the video feed it is necessary to power the DeltaQuad Evo and establish a radio connection between the Evo and the DeltaQuad Controller.

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.

Once the DeltaQuad Controller is connected to the Wi-Fi network or hotspot you can determine the "Wi-Fi IP address" that was assigned to the DeltaQuad Controller by opening the Evo Control Panel.

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

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

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

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

Go to the "Network" tab.

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.

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

Click "Next" in the "Source" window.

Click "Next" in the "Destination Setup" window.

Click "Next" in the "Transcoding Options" window.

Click "Stream" in the "Option Setup" window.

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