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...
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...
This paper explores user-centered metadata delivery through the example of hierarchically organized meeting audio metadata. Audio annotations that describe meeting scenarios can vary from low-level signal-based descriptors to high-level semantics. Users of meeting metadata also have widely varying requirements and hence want metadata at varying levels and detail. Thus, for efficient metadata access,...
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...
