In 2004, Apple introduced what was then a revolutionary technology that let you play music from iTunes on your Mac or Windows PC on speakers that could have been in the next room or anywhere else within your network. This technology was called AirTunes, and the speakers you wanted to play the music over had to be connected to an AirPort Express or Apple TV device. Yes, we are talking about the first generation Apple TVs here.
AirPlay is a natural evolution of AirTunes as it moves beyond sound to encompass video as well. It is only now with the launch of newer iPads and iPhones — and also with the new features in iOS 5 that AirPlay provides ample solutions for you to present your entire presentation. Essentially, if you want to present from your iPad 2 (or even an iPad 1), this is what you need:
That’s all you need to have in place — and frankly Apple TV 2 is even smaller than an iPad — so, that does not hamper your portability. It is a good idea to ensure though that the venue where you will present has projectors equipped with HDMI inputs. If the projector at the venue you will present has been suspended from the ceiling or has been fitted somewhere else, then you may only get a VGA cable to attach your Apple TV 2 to — and that will not work well for you to provide a professional and predictable presentation.
Everything we discussed so far in this post was relevant only to presenting with an iPad, and not necessarily for other AirPlay scenarios. The rest of this post will look at these other scenarios — feel free to ignore this section if this is not something you want to explore.
AirPlay lets you transmit data such as audio and video content wirelessly from:
Using AirPlay, you can send these audio and video signals to an AirPlay receiving device, such as:
In addition, Wikipedia’s AirPlay page provides a historical look at this technology along with some discussions about AirPlay alternatives.
