Advantage of Airplay?

[Jean-Marie]

Not sure about EQ but Apple AirPlay is only for Apple products AFAIK. It's wifi based so it's automatically detected once the device is on the same wifi network. One advantage is there is no manual Bluetooth hunting to get connected. It's just present at all times to be selected. Another advantage is there is no need to use Spark. So I guess the feature would only benefit Apple users.

There is one potential additional advantage: If correctly implemented, Airplay sends back latency information so that the computer delays the video to keep audio and video in sync.

At least it was the case between my iPad, iPhone and Macs when I was using it.

VERY interesting. When you say correctly implemented, I take it you mean if Devialet correctly implements AirPlay? And Airfoil for Windows?

Otherwise it sounds like the Apple Airplay shares latency info so audio and video are sync'd....impressive. Is this documented in a white paper or other document I can read more on?

I don't have any privileged access to the airplay protocol, so I don't know for sure, but I have been using several times watching video on my mac, my iPad or my iPhone while streaming the audio via airplay to a airport express access point itself connected via a Toslink to a DAC and amplifier. (That we before my Devialet time)
Synchronization was good even when using different network topologies (different number of hops and load). This is not possible without network latency compensation.
