So instead of the Control Point stacking up multiple URI’s and feeding them to the player one by one, it will trigger actions on the player for it to add and remove URI’s to its playlist. Furthermore, in addition to playing one certain URI at a time, Sonos players are capable of managing their own now playing queue.

The Control Point uses UPnP to discover both the server and renderer capabilities in a Sonos player and establishes communication to use these services in order to browse and play content. So instead of browsing a UPnP enabled NAS, the Control Point (for example the Sonos Software on your PC) browses the Sonos player itself. Any Sonos player allows you to add shared folders of content from anywhere on your network and will present these folders as a UPnP MediaServer. Basically, you browse the Media Server for the URI of you track and then tell the MediaRenderer to play that URI.Ī Sonos player actually performs both the tasks of a MediaServer and MediaRenderer. The user interacts with the Control Point’s UI to locate and select the desired content on the MediaServer and to select the target MediaRenderer. display or listen to) on the MediaRenderer. In this scenario, the MediaServer contains (entertainment) content that the user wants to render (e.g. These three components (each with a well-defined role) work together to accomplish the task. play) individual items of content on a specific rendering device. A content playback scenario involves three distinct UPnP components: a MediaServer, a MediaRenderer, and a UPnP Control Point.

The most common use for UPnP is to render (i.e. Sonos uses standard UPnP, which allows you to discover the device and communicate with it to establish functional network services. Here are some things we came across that should answer all three questions.įirst of all, let’s look at the Sonos product itself. “When will the module support Spotify?”.“Why doesn’t the module support Spotify?”.Ever since we finished our Sonos module for Crestron the same questions always come up:
