This document uses the following terms:
device description document (DDD): A document used to specify device information and its capabilities, as described in the UPnP standard [UPnP].
digital item declaration language (DIDL-Lite): A subset of the Digital Item Declaration Language (DIDL), which is an XML dialect developed within ISO/MPEG21.
Digital Living Network Alliance (DLNA): A cross-industry organization of leading consumer electronics, computing industry, and mobile device companies, which are focused on delivering interoperability guidelines to allow entertainment devices in the home to operate with each other. DLNA has embraced WMM for its QoS strategy.
Digital Media Player (DMP): A device class defined in the DLNA Guidelines. A DMP is an UPnP control point, which means that it invokes UPnP actions on UPnP devices. The DMP is not itself a UPnP Device.
Digital Media Renderer (DMR): A Device Class defined in the DLNA Guidelines. A DMR is UPnP Device that implements the UPnP MediaRenderer Device type.
Digital Media Server (DMS): A device class defined in the DLNA Guidelines. A DMS is an UPnP device that implements the UPnP MediaServer device type.
DLNA guidelines: The DLNA Networked Device Interoperability Guidelines [DLNA] consist of three volumes that provide vendors with the information required to build interoperable networked platforms and devices for the digital home, including architecture and protocols, profiles for media formats, and link protection.
Hypertext Transfer Protocol (HTTP): An application-level protocol for distributed, collaborative, hypermedia information systems (text, graphic images, sound, video, and other multimedia files) on the World Wide Web.
Microsoft Compatibility Extension Flags (MCEF): Flags provided by DMRs and DMPs to filter specific res elements exposed to these devices.
Microsoft Media Property Extensions (MMPE): Additional metadata properties that describe a media item that further enriches the metadata properties defined by [UPnP].
Microsoft Power Management Extensions (MPME): XML tags used to communicate the devices support of magic packets.
Microsoft ProtocolInfo Extensions: Extensions to the ProtocolInfo syntax, defined by Microsoft.
ProtocolInfo: As specified in [UPNPCNMGR] section 2.5.2.
Real-Time Streaming Protocol (RTSP): A protocol used for transferring real-time multimedia data (for example, audio and video) between a server and a client, as specified in [RFC2326]. It is a streaming protocol; this means that RTSP attempts to facilitate scenarios in which the multimedia data is being simultaneously transferred and rendered (that is, video is displayed and audio is played).
res: Identifies a resource. A resource is typically some type of a binary asset, such as a photo, song, video, etc. A res element contains an URI that identifies the resource.
Universal Plug and Play (UPnP): A set of computer network protocols, published by the UPnP Forum [UPnP], that allow devices to connect seamlessly and that simplify the implementation of networks in home (data sharing, communications, and entertainment) and corporate environments. UPnP achieves this by defining and publishing UPnP device control protocols built upon open, Internet-based communication standards.
UTF-8: A byte-oriented standard for encoding Unicode characters, defined in the Unicode standard. Unless specified otherwise, this term refers to the UTF-8 encoding form specified in [UNICODE5.0.0/2007] section 3.9.
XML: The Extensible Markup Language, as described in [XML1.0].
MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
