abstract = {Content delivery over the Internet, in order to allow
\emph{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 \emph{InfoPyramid} (2) A set of
\emph{transcoders} for converting modality or resolution, and (3) a
\emph{customizer} that selects the best content representation to meet
the client capabilities while delivering the most value.
The InfoPyramid provides a multi-modal, multi-resolution representation
hierarchy for multimedia. The raw content components, such as text,
audio, images, video, etc., are ingested by the system into
InfoPyramids. Next, the transcoder populates the Infopyramid structures
with multi-resolution, multi-modal versions of the content. The number
of possible renditions of the multimedia content is potentially
combinatorial in the number of content elements. The customization
module uses the client device characteristics as constraints to pick
the best content representation. Content value is computed on the basis
of publisher preference guidelines and the content transcoding. We
illustrate with a system that deliver news stories customized to
diverse clients such as workstations, PCs, PDAs, cellular phones,
pages, etc.},
