UPnP Services Used:

AV Architecture

The UPnP reference standard used by the network devices is the AV Architecture in its version '1'. It specifies the two classes of UPnP devices used as network server and playback audio device; they are in particular:

Associated with these classes there are four UPnP services:

  1. ContentDirectory:1 (implemented by NAS)
  2. AVTransport:1 (implemented by Smart Speaker)
  3. RenderingControl:1 (implemented by Smart Speaker)
  4. ConnectionManager:1 (not implemented)
