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.
