This document describes the overall UPnP AV Architecture, which forms the foundation for
the UPnP AV Device and Service templates. The AV Architecture defines the general
interaction between UPnP control points and UPnP AV devices. It is independent of any
particular device type, content format, and transfer protocol. It supports 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 the PC. The AV
Architecture allows devices to support different types of formats for the entertainment content
(such as MPEG2, MPEG4, JPEG, MP3, Windows Media Architecture (WMA), bitmaps (BMP),
NTSC, PAL, ATSC, etc.) and multiple types of transfer protocols (such as IEC-61883/IEEE-
1394, HTTP GET, RTP, HTTP PUT/POST, TCP/IP, etc.). The following clauses describe the
AV Architecture and how the various UPnP AV devices and services work together to enable
various end-user scenarios.All current amendments available at time of purchase are included with the purchase of this document.
