Set Your Multimedia Application Free with BRisa Framework: An Open Source UPnP Implementation for Resource Limited Devices

This paper presents the BRisa UPnP A/V framework. BRisa is a framework that allows users to discover multimedia devices, share, search and render multimedia content over the local networks or remotely through the Internet. It has been developed using UPnP specifications, which makes use of standard Internet protocols and services, such as HTTP, UDP and SOAP. BRisa is composed of three main applications: the BRisa Media Server, the BRisa Media Renderer and the BRisa Control Point, each of them plays a specific role in our entire UPnP solution. In this paper we briefly describe our UPnP implementation and discuss a set of features implemented to share audio/video/image in a computer network. We also explain the application of our approach to resource limited devices, more specifically for the N800 Nokia Internet Tablet.
