This device template is compliant with the UPnP Device Architecture version 1.0. It defines a device typereferred to herein as MediaRenderer:1.The MediaRenderer template defines a general-purpose device template that can be used to instantiate anyConsumer Electronic (CE) device that is capable of rendering AV content from the home network. It exposes aset of rendering controls in which a Control Point can control how the specified AV content is rendered. Thisincludes controlling various rendering features such as brightness, contrast, volume, etc.Example instances of a MediaRenderer include traditional devices such as TVs and stereo systems. Some morecontemporary examples include digital devices such as MP3 players and Electronic Picture Frames (EPFs). Althoughmost of these examples typically render one specific type of content (e.g. a TV typically renders videocontent), a MediaRenderer is able to support a number of different data formats and transfer protocols. Forexample, a sophisticated implementation of a TV MediaRenderer could also support MP3 data so that itsspeakers could be used to play MP3 audio content.The MediaRenderer device template is very lightweight and is easy to implement on low-resource devices such asan MP3 player. However, it can also be used to expose the high-end capabilities of such device as a PC.A full-featured MediaRenderer exposes the following capabilities:? Control various rendering characteristics? Expose the supported transfer protocols and data formats? Control the flow of the content (e.g. FF, REW, etc), if appropriate depending on the transfer protocol.The MediaRenderer DOES NOT enable Control Points to:? Send AV content to another device? Retrieve any type of meta-data associated with the content
