This paper describes a system that is able to take arbitrary semantic metadata, and utilize it in the multimedia delivery decision-making process. Format independence is achieved using schema languages to describe the details of any given content or metadata, so that declarative mapping rules can be specified for translating from format-specific data points to format-independent concepts that are...
Several recent standards address virtual containers for rich multimedia content: collections of media with metadata describing the relationships between them and providing an immersive user experience. While these standards - which include MPEG-21 and TVAnytime - provide numerous tools for interacting with rich media objects, they do not provide a framework for streaming or delivery of such content...
Intelligent multimedia delivery uses semantic information about content to enhance the delivery process. This paper proposes a model for intelligent multimedia delivery that advances the state of the art by incorporating a concept of semantic distortion into the delivery optimization process. Furthermore, the model combines format-independence with rate-distortion optimization to provide a flexible...
The Bitstream Binding Language (BBL) is a new technology developed by the authors and being standardized by MPEG, which describes how multimedia content and metadata can be mapped onto streaming formats. This paper describes how BBL can be used to enhance the interoperability of multimedia content by providing a generic mechanism for the translation of content between formats. As new content formats...
The bitstream binding language (BBL) is a new technology developed by the authors and being standardized by MPEG, which describes how multimedia content and metadata can be mapped onto streaming formats. This paper describes a particular application of BBL-format-independent multimedia streaming. This means that streaming servers no longer require additional software modules in order to support new...
Bitstream binding language (BBL) provides an abstraction layer between XML multimedia containers and the way their resources and metadata are published in a bitstream. It allows multiple bindings from a single source document to facilitate interoperability and applicability of the multimedia content to a wide range of terminals and users. BBL introduces a number of features not found in other XML...
