About

The Trace Universal Control Hub (UCH) is a reference implementation of the Universal Remote Console (URC) standard by the Trace R&D Center at the University of Wisconsin-Madison, USA. The UCH software is available in two versions:

UCHj (Java implementation, based on JDK 1.5 or later)
UCHe (C/C++ implementation for desktop or embedded systems)

Note: The UCH reference implementation supersedes the previous "Trace URC Software Development Kit (SDK)". The code of the URC SDK has been subsumed under the UCH project.

Standards

The UCH reference implementation is based on the following standards:

ISO/IEC 24752-1:2008, Information Technology - User Interfaces - Universal Remote Console - Part 1: Framework
ISO/IEC 24752-2:2008, Information Technology - User Interfaces - Universal Remote Console - Part 2: User Interface Socket Description
ISO/IEC 24752-4:2008, Information Technology - User Interfaces - Universal Remote Console - Part 4: Target Description
ISO/IEC 24752-5:2008, Information Technology - User Interfaces - Universal Remote Console - Part 5: Resource Description
URC Consortium: Universal Control Hub Specification. Working draft 2008-06-25.
URC Consortium: URC-HTTP Protocol Specification. Working draft 2008-06-25 .

Features

The UCH reference implementation in a nutshell:

Light-weight Universal Control Hub implementation
Partial conformance with ISO/IEC 24752 (see individual release notes for a list of supported and unsupported features)
Supports the following targets:
- Trace Satellite Box Applet (UPnP enabled demo target)
- UPnP AV 1.0 media servers and media renderers
- Generic target: Simulation of any target based on scripts (only for UCHj)
Supports the following controllers:
- any controller/application that uses the URC-HTTP protocol
- PlayIt - Flash controller for PDAs and smart phones (code already included in UCH software package)
- DragIt - DHTML controller for Internet Explorer (code already included in UCH software package)
- "Webclient" Javascript code library for building DHTML-based controllers (code already included in UCH software package)

Intended Users

The following users should be interested in the UCH reference implementations:

Device manufacturers: to make their devices remotely controllable via the URC standard
UCH manufacturers: to provide a control hub based on the URC standard
Controller manufacturers: to make their remote control software work with any UCH or URC-compliant target
Researchers: to investigate and use existing URC-compliant solutions in their research and prototype projects
