Full title and description

Information technology — UPnP Device Architecture — Part 3-13: Audio Video Device Control Protocol - Rendering Control Service (ISO/IEC 29341-3-13:2008). This part of the ISO/IEC 29341 series defines the Rendering Control Service (service type RenderingControl:1) used by UPnP AV renderers to expose and manage rendering attributes such as volume, mute, brightness, contrast, color controls and keystone, together with the service description, state variables, actions and eventing behavior required for network control points to query and adjust those attributes.

Abstract

ISO/IEC 29341-3-13:2008 specifies a UPnP Rendering Control Service template compliant with the UPnP Device Architecture v1.0. It defines the service model, state variables (for example Mute, Volume, VolumeDB, Loudness, Brightness, Contrast, Sharpness, ColorTemperature, RGB gains, Keystone, PresetNameList and LastChange), the actions used to read and set those variables, XML service description semantics and eventing semantics used by control points and renderers in home and small‑business AV networks.

Scope

This standard provides a formal service template for a Rendering Control Service to be implemented by UPnP AV Media Renderer devices. It covers the service type and namespace, state variables describing renderer capabilities and current rendering attributes, action signatures (SOAP-based) to get and set attributes, eventing semantics (including the LastChange mechanism for efficient event notifications), and test criteria for conformance. It is intended for use in unmanaged or ad-hoc networks such as home and small-business AV environments.

Key topics and requirements

• Definition of the RenderingControl:1 service type and its XML service description.
• State variables for audio and video rendering attributes (Mute, Volume, VolumeDB, Loudness, Brightness, Contrast, Sharpness, ColorTemperature, RGB gains/black levels, Horizontal/VerticalKeystone, PresetNameList, LastChange, etc.).
• Action set (SOAP interfaces) for getting and setting rendering attributes and presets.
• Eventing and update model, including use of the LastChange semantic for compact change notifications.
• Conformance and test criteria for implementers and test labs to validate correct behavior of renderers and control points.

These requirements enable interoperable control of renderer characteristics across UPnP control points and rendering devices.

Typical use and users

Primary users are device and firmware developers of networked AV renderers (e.g., networked speakers, TVs, set-top boxes, media players), developers of UPnP control point applications (mobile/desktop apps and gateways), conformance test houses and integrators building UPnP‑based home AV systems. The standard is used to ensure interoperable control of rendering attributes (volume, mute, video picture settings, etc.) across devices and control software.

Related standards

FAQ

Q: What is this standard?

A: ISO/IEC 29341-3-13:2008 is the UPnP Rendering Control Service specification that defines how networked AV renderers expose and allow remote control of rendering attributes (audio and video) to UPnP control points.

Q: What does it cover?

A: It covers the service type and XML description, state variables for renderer attributes (e.g., Volume, Mute, Brightness, Contrast, Color controls, Keystone), the SOAP actions to read and modify those attributes, eventing semantics (including LastChange) and conformance test criteria.

Q: Who typically uses it?

A: Device manufacturers (firmware/hardware teams), application developers building UPnP control points, system integrators and testing laboratories use this standard to implement and validate interoperable rendering control functionality.

Q: Is it current or superseded?

A: The published edition is from 28 November 2008 (Edition 1.0). Implementers should check the ISO/IEC catalogue or national standards bodies for any later revisions, Level 2 extensions or confirmations that might affect implementation decisions. Standards in the 29341 series have had later Level‑2 and additional part publications; verify the latest status before assuming this is the most current applicable text.

Q: Is it part of a series?

A: Yes — ISO/IEC 29341 is a multipart series specifying UPnP Device Architecture and device control protocols for AV, security cameras, device security, QoS, remote user interface and other device classes. Part 3 covers Audio/Video Device Control Protocols and Part 3-13 is the Rendering Control Service within that part.

Q: What are the key keywords?

A: UPnP, RenderingControl, Media Renderer, Volume, Mute, Brightness, Contrast, ColorTemperature, Keystone, LastChange, SOAP, XML.
