Summary:MPEG reconfigurable video coding (RVC) is a new platform-independent specification methodology chosen by the MPEG community for describing coding standards. This methodology aims at producing abstract decoder models (ADMs) of MPEG decoders as programs described in a dataflow language namely “RVC-CAL Actor Language” (RVC-CAL). RVC-CAL naturally expresses potential parallelism between tasks of an application, which makes an ADM description suitable for implementation to a wide variety of platforms, from uniprocessor systems to FPGAs. MPEG RVC eases the development process of decoders by building decoders at a library-component level instead of using monolithic algorithms, and by providing a library of coding tools standardized in MPEG. This paper presents new mechanisms based on the low level virtual machine that allow the conception of a decoder able to dynamically instantiate several RVC decoder descriptions. This decoder, unlike static decoders generated by RVC tools, keeps de facto the features of an RVC description namely portability, scalability and reconfigurability.
