DS Technical Architecture FAQ
This page is intended for the technically inclined who wish to understand the technology the DS uses.
Technically, what is a DS?
The DS offers a service to the network; the service of turning data into music at the highest possible quality. It exposes this service to the network over an open standard protocol called UPnP.
What is UPnP?
UPnP is a suite of protocols providing discovery, control, and eventing.
- Discovery allows control points to find devices offering particular services on the network without any prior knowledge of their existence or location.
- Control allows control points to request a service from a device.
- Eventing allows devices to notify control points of changes in their state.
It is an open, published standard requiring no fee to obtain the specification.
What is UPnP AV?
The UPnP audio visual standard defines a common way for various parts of a audio visual home network to interact. One of the key insights of this specification was the indentification of the following three parts of the network:
- Media Servers
- Media Renderers
- Control Points
