Frequently a renderer is the final device in the UPnP AV chain turning music from streamed content into something audiophiles can hear. A renderer can convert network based audio into another form of digital audio such as S/PDIF and pass this audio along to another non-UPnP AV device or a renderer can convert the network audio into analog for playback. Computer audiophiles are likely most familiar with renderers as several HiFi companies manufacturer components that render (convert and/or reproduce) audio. Other UPnP AV devices can then see information about what it contains, what communication protocols it supports, what type of music it can serve, and details such as album, artist, track, etc…Ī Media Renderer is a device that either converts and/or reproduces audio. The Synology NAS simply broadcasts on the network that it's available. When enabled this application advertises the NAS as a UPnP AV Media Server and allows control points to browse music and stream it from the NAS directly to a UPnP AV playback device. Synology NAS units ship with a Media Server application. AV Transport Service is used by a control point for actions including Play, Pause, Stop, Seek, etc… This service also duplicates itself on the Media Server to enable streaming to multiple playback devices simultaneously.Įxample - A very common Media Server for computer audiophiles is a network attached storage (NAS) unit. Through this service a control point instructs a Media Server for its next content delivery to a renderer.Ĭ.

Connection Manager Service is what manages Media Server connections to playback devices (renderers). Using this information a control point can determine if the playback divide (renderer) is capable of handling the content.ī. This service also identifies the data formats supported by the server for its content. Content Directory Service enables a control point to browse the Media Server and view information about available music such as metadata (album title, artist, track name, etc…). Most UPnP AV Media Servers contain three services, a ContentDirectory Service, a ConnectionManager Service, and an AVTransport Service.Ī. Media Servers can stream content to multiple devices and be controlled by multiple control points simultaneously. The UPnP AV architecture specifies three important devices, each with its own services, for audio playback, the Media Server, Media Renderer, and Control Point.Ī Media Server is a device that stores content, advertises the availability of this content for streaming across the network, and enables browsing/searching this content from control points. The descriptions below are tailored for computer audiophiles by referencing audio and music rather than all the media types (video, photos, etc…) UPnP AV can accommodate. For example enabling audio to flow from a NAS to an audio playback device without intervention from a controller. A main goal of UPnP AV is interoperability between controllers and AV devices. UPnP AV is a refinement of the general UPnP protocols. UPnP can be seen as a high level framework that has been refined by the UPnP AV architecture for increased performance in audio and video environments. Through use of common protocols UPnP devices automatically advertise their services or capabilities enabling auto discovery of devices on a network. UPnP devices don't use device drivers, like USB printers and other hardware, for communication and interoperability.

Universal Plug and Play consists of several protocols or rules that enable networked hardware devices and software applications to communicate and work together without end user configuration. I hope it will provide all the information computer audiophiles need to understand and enjoy UPnP based audio playback. This guide will not turn a novice into an expert. The more one digs into the UPnP protocols the more divergent information with common frustration one finds. Ironically UPnP is extremely simple for end users and a bear for product producers. It's used in both two channel single room systems and whole house network audio distribution.

UPnP is the most common network audio protocol in use today.

Network based audio can be delivered using several different protocols and technologies such as UPnP, DAAP (Apple), and Ravenna among others.

The guide describes UPnP based home audio reproduction, provides use pro and cons of UPnP, examples, and recommendations for successful UPnP audio implementations. The following guide was designed for audiophiles.
