''UPnP AV architecture'' is an audio and video extension of the UPnP, supporting a variety of devices such as TVs, VCRs, CD/DVD players/jukeboxes, settop boxes, stereos systems, MP3 players, still image cameras, camcorders, electronic picture frames (EPFs), and personal computers.  The UPnP AV architecture allows devices to support different types of formats for the entertainment content, including MPEG2, MPEG4, JPEG, MP3, Windows Media Audio (WMA), bitmaps (BMP), and NTSC, PAL or ATSC formats.  Multiple types of transfer protocols are supported, including IEEE 1394, HTTP, RTP and TCP/IP.<ref name="UPnP-av-AVArchitecture-v2">{{cite web |title=UPnP AV Architecture |url=http://upnp.org/specs/av/UPnP-av-AVArchitecture-v2.pdf |date=31 March 2013 |access-date=11 September 2014 |publisher=[[UPnP Forum]] }}</ref>

On 12 July 2006, the UPnP Forum announced the release of version 2 of the UPnP Audio and Video specifications,<ref>{{cite web |url=http://www.upnp.org/news/documents/AV2_PR20060712.pdf |title=UPnP Forum Releases Enhanced AV Specifications Taking Home Network to the Next Level |date=12 July 2006 |access-date=11 September 2014 |publisher=[[UPnP Forum]] }}</ref> with new ''MediaServer'' (MS) version 2.0 and ''MediaRenderer'' (MR) version 2.0 classes.  These enhancements are created by adding capabilities to the MediaServer and MediaRenderer device classes, allowing a higher level of interoperability between products made by different manufacturers.  Some of the early devices complying with these standards were marketed by [[Philips]] under the [[Streamium]] brand name.

Since 2006, versions 3 and 4 of the UPnP audio and video device control protocols have been published.<ref>{{cite web
