Could someone help me understand exactly how Airplay will work? As you will soon see, I'm not a techno-genius. So let's say I'm sitting on my couch in front of my home stereo and I want to "airplay" something from my PC. I can use my iPhone and pick what I want to listen to and my PC will then send the music to my stereo. *Is my computer sending the signal through my wireless router to my stereo receiver (or perhaps they are wire networked) or is it sending the signal through some other source kind of like bluetooth does? *If the signal is passed through a wireless router, does the stereo receiver that receives it then become a networked peripheral on my PC? *Is my computer sending the digital signal directly to my receiver which then uses it's own digital to analog converter to pass it on to the speakers? Or does the computer decode it the files and send the receiver a signal of what it should sound like?
