Screen mirroring with Apple TV

How to play a Digital Theatre+ video on a Television connected to an Apple TV device using Mac OS and AirPlay

Thursday 20 October 2022: Current versions of web browsers restrict the ability to screen mirror any content encrypted by DRM (Digital Rights Management). Therefore, given that Digital Theatre+ provides protected content, screen mirroring does not currently work on the latest version of web browsers (Chrome 105 and above, Firefox 106 and above and Safari 15.3 and above). When using these browsers, sound will be heard however video will not appear. We are actively working on a solution to allow our customers to use screen mirroring. 

If running current web browser versions, we would recommend using a physical HDMI connection to project our content. 

If users are running older versions of web browsers, then Digital Theatre+ videos might be able to be played on a Television, via an Apple TV device, using Apple Mac OS devices with Screen Mirroring. 

Screen Mirroring is a feature of Mac OS, sometimes called AirPlay or AirPlay Mirroring.  It lets you send what’s on your Mac to a HD Television wirelessly via an Apple TV device.

The following has been tested using:

  • Apple TV 4K (32GB) Model A2169 running tvOS 16.0 (20J373)
  • Mac OS Monterey 12.2
  • Microsoft Edge 106.0.1370.47
