1.1 Glossary

  • Article

This document uses the following terms:

Advanced Systems Format (ASF): An extensible file format that is designed to facilitate streaming digital media data over a network. This file format is used by Windows Media.

content: Multimedia data. content is always in ASF, for example, a single ASF music file or a single ASF video file.  Data in general. A file that an application accesses. Examples of content include web pages and documents stored on either web servers or SMB file servers.

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 Controller (DMC): A Device Class defined in the DLNA Guidelines. A DMC is a UPnP Control Point, which means that it invokes UPnP actions on UPnP Devices. The DMC is not itself a UPnP Device. The DMC invokes UPnP actions on a DMR, requesting the DMR to start streaming from a DMS.

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.

little-endian: Multiple-byte values that are byte-ordered with the least significant byte stored in the memory location with the lowest address.

SOAP: A lightweight protocol for exchanging structured information in a decentralized, distributed environment. SOAP uses XML technologies to define an extensible messaging framework, which provides a message construct that can be exchanged over a variety of underlying protocols. The framework has been designed to be independent of any particular programming model and other implementation-specific semantics. SOAP 1.2 supersedes SOAP 1.1. See [SOAP1.2-1/2003].

streaming: The act of transferring content from a sender to a receiver.

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.

universally unique identifier (UUID): A 128-bit value. UUIDs can be used for multiple purposes, from tagging objects with an extremely short lifetime, to reliably identifying very persistent objects in cross-process communication such as client and server interfaces, manager entry-point vectors, and RPC objects. UUIDs are highly likely to be unique. UUIDs are also known as globally unique identifiers (GUIDs) and these terms are used interchangeably in the Microsoft protocol technical documents (TDs). Interchanging the usage of these terms does not imply or require a specific algorithm or mechanism to generate the UUID. Specifically, the use of this term does not imply or require that the algorithms described in [RFC4122] or [C706] must be used for generating the UUID.

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.

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.
