Presentation Processing Support for Adaptive Multimedia Applications

This paper describes the design of and implementation of Presentation Processing Engines (PPEs) that provide flexible control over QoS to manage heterogeneity in networks, end-systems and compression formats. Development of PPEs is facilitated by a framework that provides the modular architecture, data types, and transformations common to most codecs, filters, transcoders etc. to facilitate the implementation of emerging compression standards and their integration into media processing applications. By allowing fine-grained composition of compression and image processing modules, the framework facilitates the development of extensible presentation processing engines that can be dynamically configured to adapt to changes in resource availability and user preferences.
