Multimedia content customization for universal access

Content delivery over the Internet, in order to allow universal access, needs to address both the multimedia nature of the content and the capabilities of the diverse client platforms the content is being delivered to. We present a system that tailors multimedia content to optimally match the capabilities of the client device requesting it. This system has three key components: (1) a representation scheme called the InfoPyramid, (2) a set of transcoders for converting modality or resolution, and (3) a customizer that selects the best content representation to meet the client capabilities while delivering the most value.
