Overview

Following a few simple rules and best practices will go a long way toward ensuring a positive experience when using the Apple TV in our environment.

The chart below shows some suggestions for when to plug in and when you should be able to mirror to the Apple TV wirelessly.

You may think "I have an Apple TV at home and I can stream a movie wirelessly without any hassle.  Why doesn't it work here?"  The answer mostly has to do with wireless network density.  In a classroom, there are often 30 or more wireless signals talking to one access point.  Imagine an intersection with 30 lanes converging on it and one traffic cop directing all of the traffic.  That's the wireless access point.  How quickly does that traffic move?  Now imagine that all 30 of those lanes have cars backed up for 10 miles.  Your signal - your lane - each car is one frame of the movie clip you are trying to show.  

Picture it that way, and our advice against trying to stream wirelessly in our environment should make sense.  We have optimized things as much as we can, and continue to do so as Apple offers new suggestions or we get ideas from the community of schools using Apple TVs this way.  Everyone trying to do what we are doing runs into the same issues.

The steps below offer a few more suggestions.

Step-by-step Guide

Apple TV physical placement

If the Apple TV device is hidden behind a TV (or other furnishings), let us know and we will place it elsewhere to get a less obstructed signal.

We will also be reviewing all rooms for placement too close to digital projectors, as that can also compromise the signal.


AirPlay in Safari

In the Safari browser, when streaming from a site such as YouTube, look for an option to stream using AirPlay.

Click the AirPlay icon to stream the content directly from the Apple TV rather than from the MacBook.

Note that while the video window will appear blank on the MacBook while streaming, you can still control (pause and play) the video from the MacBook.

Don't use Chrome for streaming

Chrome uses more system memory than Safari.  Every tab open in Chrome uses additional system memory.  This compounds the wireless traffic issue, and cause stutter or lag even when using a wired connection.

Chrome is the biggest offender, but if you have many programs open that can also be a problem.  Try closing some programs (you will need to Quit, not just close the program.  Usually there is a quit option in the named menu of the program).
