It is discoverable, exposes an UPnP description document and UPnP services like AVTransport and ConnectionManager or RenderingControl. Because it is not discoverable, you cannot control it with PlayTo.Ī DMR (aka Digital Media Renders) is a device that can accept commands received from the network. A DMP is not discoverable on the network, it just discovers and consumes content. So any UPnP device is able to talk with a DLNA device so to a Win7 machine.ĭLNA specifies 4 type of devices: DMP, DMR, DMC and DMS.Ī DMP (aka Digital Media Player) is a device, that is capable of finding and browsing remote servers (DMS=Digital Media Servers) and consume content (or pull content). DLNA is just a layer of standardization on top of UPnP. I'm wondering if you need to be a member of the DNLA to actually get access to the spec? Alternatively, I know DLNA is built on UPnP, it wouldn't exactly do what I want, but it would be a step in the right direction, so, to revise my question does anybody know of any open-source C/C++ or Java (preferable) libraries that would help me implement UPnP or DLNA? However, I'm having a really difficult time finding any sort of documentation on DLNA. If you have any documentation from MS or otherwise that would be awesome although not the crux of the question.Įdit: I discovered that the Windows 7 Play-to functionality is based on DLNA and any device supporting DLNA (I think) can be used as a destination for the Play-To context menu.

Does anybody have experience working with this API? Is this do able over a couple of weeks (prototype, just proof of concept, not end-user ready) or is it too much for a project of this scope? Note: I'm not looking for code samples, just an assessment of the feasibility of this project. For a semester project, I had the idea to implement Windows 7's Play to infrastructure to either use a phone as the end point (the player) or to stream stuff from the phone to a Windows 7 machine.
