# Instructor unable to play HD video purchased from iTunes

# Scenario

An instructor has their laptop connected to a projector in a classroom, and tried to play an HD video that they purchased in iTunes. iTunes displays an error saying it cannot play the video.

# Why

The video purchased in iTunes is subject to <span class="caps">HDCP</span> – High-bandwidth Digital Content Protection. Basically it’s an encrypted signal to prevent copying, and *every* piece of of equipment in the signal chain must support <span class="caps">HDCP</span> for it to work. If iTunes and the OS detect that you are using a non-digital (eg. <span class="caps">VGA</span> connection) or non-compatible equipment, it won’t play the video.

# Solutions

**Download the SD version**  
Although HD is usually downloaded first, the individual should be able to look back at their purchase history and download the SD version. Instructions on accessing your purchase history: [support.apple.com/kb/HT2727](http://support.apple.com/kb/HT2727)  
Similarly, a <span class="caps">DVD</span>-ripped copy will also be playable.

**Purchase an HD Fury dongle**  
While expensive ($250+), this piece of equipment will convert a digital signal into analog (<span class="caps">HDMI</span> to <span class="caps">VGA</span>) and allow the video to play. It simply needs to be connected between the computer and the video cable.

**Upgrade your room**  
Buy new equipment and redesign your space to be all-digital so that all pieces of the signal chain support <span class="caps">HDCP</span>.
