I'm looking for a way to create a streaming environment within my home network. I figured out DLNA or Airplay are probably the way to go but now I have a problem figuring out with which device I'm able to create a stream which is then consumed by different clients (speakers, ...) I know how to access files (especially music) through the network. I have a Synology NAS / Raspberry Pi / Home server ready to be configured. The stream producer should be running all the time (probably on the nas / homeserver) and the consumer should be able to consume the stream whenever they are turned on. Any ideas?
If you the streaming device eg: mobile / iPod is in a Bluetooth range then probably you can make use if NFC which should be available on all the latest devices or you can take advantage of UPnP technology.
