An open software architecture for structured data elaboration and transcoding

In this paper, we propose a software architecture model for the development of elaboration/transcoding modules for structured data. We define a flexible implementation approach which makes it easy to generate modules that deliver good performance. The solution has also the objective to foster high reusability and independent coding of processing and I/O modules. A set of modules developed using this approach have proved to deliver good performance and flexibility in processing MPEG2 video streams. This paper reports measurements and comparison results with a standard MPEG2 video decoder, that confirms the potential of the approach.
