Universal Plug'n Play (UPnP) Reference

Introduction

This section discusses devices compliant to UPnP (Universal Plug'n Play) architecture. This architecture has been developed over +10 years by member companies of the UPnP Forum. Although this section focuses on UPnP device models defined for AV (Audio-Visual) devices, UPnP defines a number of other standard device models for Home Network Gateways, Telephony, Remote Access, and Home Automation applications.

Further information concerning membership in the UPnP Forum may be obtained at: http://www.upnp.org

UPnP AV Architecture

UPnP AV (Audio-Visual) Architecture provides an informative overview of the UPnP model for media serving and media rendering devices. It is a good starting point for readers becomming familiar with UPnP architecture related to audio-video device support.

UPnP Device Architecture

UPnP Device Architecture provides the basic mechanisms for discovering, advertising, and commanding of UPnP devices. All UPnP Devices implement and comply with the requirements in this specification.

  • UPnP AVTransport Service
    The UPnP AVTransport specification defines actions and variables which control connection to and playback of AV content on a standard UPnP MediaRenderer device. Examples may include: setting a playback URL, issuing Play, Stop, Seek, and Pause operations, determining the current state of a rendering device (Playing, Stopped, Paused, etc).

  • UPnP Connection Manager
    The UPnP ConnectionManager service defines actions and variables to allocate and control multiple sessions on a standard UPnP MediaRenderer device. Examples may include allocating a Picture-in-Picture window on a rendering device, or allocating an additional audio player instance on a rendering device.

• The following references define services provided by a standard UPnP MediaServer device:
  
  
  • UPnP Content Directory Service
    The UPnP ContentDirectory service publishes metadata for stored content, broadcast content, channel lineup(s) and electronic programming guide(s). A UPnP MediaServer device may optionally serve content described by ContentDirectory service metadata or the ContentDirectory service may provide metadata referring to content residing on other home network servers.

  • UPnP Connection Manager Service
    The UPnP ConnectionManager service defines actions and variables controlling multiple sessions allocated on a standard UPnP server device. The ConnectionManager service runs on both standard UPnP MediaRender and UPnP MediaServer devices.

  • UPnP Scheduled Recording Service
    The UPnP ScheduledRecording service defines actions and variables which control creating and tracking of recording requests for a recording device. Examples may include: creating a recording request based time or electronic programming guide metadata, displaying programs already recorded and displaying and controlling pending recording activities. The ScheduledRecording service supports recording from both network (URLs) and non-network sources (such as analog and digital tuners).
