OpenHome (aka UPnP with Linn extensions) and standard UPnP/DLNA are actually closely related (but incompatible) streaming technologies rather than 'formats'. The main difference is that with OpenHome it's the streamer (aka renderer) that owns the current playlist; whereas with standard UPnP/DLNA it's the controller (aka control point) that owns the current playlist.

 

This gives the OpenHome renderer the advantage of being autonomous with regards to playing the tracks in the playlist once playback has started. It means the OpenHome renderer can sort out gapless playback for itself, allow multiple OpenHome control points on the network to interact with it without any side effects and even continue to play the entire playlist with all associated OpenHome control points switched off.

 

Contrast that with the standard UPnP/DLNA renderer which is completely reliant on the standard UPnP/DLNA control point for playback. So, the UPnP/DLNA renderer requires the standard UPnP/DLNA control point to tell it what the next track is and where to fetch it from every time the next track needs to be played. This forces gapless playback support to be an interaction between both control point & renderer and restricts the number control points that can interact with the renderer at any one time to one (otherwise you can get strange playback side effects with the various control points competing with each other to gain control over the renderer).

 

 

Note:

- Gapless playback is always supported in OpenHome and optional in standard UPnP/DLNA;

 

- OpenHome renderers cannot be controlled by standard UPnP/DLNA control points and standard UPnP/DLNA renderers cannot be controlled by OpenHome control points.

However, there are some controller applications that contain both types of control point, so can be used to control both types of renderer: eg, the BubbleUPnP Android app and Linn's older Kinsky controller (but not the newer Linn Kazoo, which is an OpenHome only controller). You can also get streamers with both types of renderer built-in: eg, Linn DS streamers and Lumin streamers;

 

- Both OpenHome control points and standard UPnP/DLNA control points can access UPnP/DLNA media servers (eg, MinimServer), to get their associated renderers to stream audio files from;

 

- OpenHome comes with optional built-in support for various extra services such as internet radio, online music streaming (currently only Qobuz & TIDAL) and synchronised multiple device playback (known as Songcast).

The main difference is gapless playback. In general I found Openhome more pleasing to use than plain vanilla UPNP but it is important that

the endpoint device support Openhome natively or you will get quirky behavior  when trying to manipulate whats playing. Used with

the linux version of Minimserver, it will get you to the limits of what UPNP protocol can do for SQ.

Thank you for the link as well as the explanation.
