How does airplay work when streaming content from an online service.
Does the content stream directly to the player (e.g. an ATV) or is it routed through the device starting the stream (e.g. iOS device)?
Too veuge of a question. There are a lot of factors that control. That. It could work either way depending on the setup of your network, where the service provider is from, if you are using Airplay or AirPlay mirroring, etc.
