A multimedia broker for ubiquitous and accessible rich media content transcoding

摘要

Entertainment multimedia applications based on synchronized continuous media are largely used on standard platforms and are becoming ubiquitous. To integrate rich and interactive multimedia in context aware applications, contents have to be produced and integrated by using mechanisms that choose and provide the richest version that meets user and device capabilities. In this context, we discuss on the design and implementation of an Internet application designed to support the development of multimedia applications for non standard devices by providing a media-brokering service. The media broker uses a SMIL-based description of the rich media and a CC/PP profile to adaptively compute the best version of the media content that can be delivered to a specific user and device.
