Structured Scalable Meta-formats (SSM) for Digital Item Adaptation
This paper motivates and develops an end-to-end methodology for representation and adaptation of arbitrary scalable content in a fully content non-specific manner. Scalable bit-streams are naturally organized in a symmetric multi-dimensional logical structure, and any adaptation is essentially a downward manipulation of this structure. Higher logical constructs are defined on top of this multi-...
متن کاملStructured Content Independent Scalable Meta-formats (SCISM) for Media Type Agnostic Transcoding
This paper develops a universal meta-format (SCISM) and methodology for representation and transcoding of arbitrary scalable content. The abstractions in the meta-format are generic enough to be applicable to any type of media with only a loose restriction on the encoding structure. Scalable bit-streams are naturally organized in a manner such that representation in compliance with the meta-for...

متن کاملDynamic and Distributed Adaptation of Scalable Multimedia Content in a Context-Aware Environment
The seamless access to rich multimedia content on any device and over any network, usually known as Universal Multimedia Access, requires interoperable description tools and adaptation techniques to be developed. To address this, MPEG-21 introduces an adaptation framework, which provides several mechanisms for making adaptation decisions according to usage environment and adapting multimedia co...
متن کاملMultichannel Distribution for Universal Multimedia Access in Home Media Gateways
Today, people collect their personal multimedia content on home media servers. In addition to consuming their content on TV sets, people are using mobile multimedia players, PCs and even mobile phones. Since those terminals have various capabilities, it is necessary to adapt the content to a more device specific version. For audio, video, and graphics scalable codecs exist which realize this go...
