abstract

Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a codec designer to produce any desired trade-off between compression performance and implementation complexity. Currently, two obstacles prevent such possibility: 1) the monolithic specification of standard technology based on imperative reference SW models, 2) interoperability that demands that this selection process be "hard-wired" into the normative description of the codec, or at best, a number of choices codified within the media syntax (i.e MPEG profiles). This talk presents an alternative paradigm for codec deployment that has been recently standardized by MPEG, known as Reconfigurable Video Coding (RVC). The new paradigm is based on high level CAL dataflow formalism and provides interesting features for the development of implementations for the next generation of multicore and heterogeneous platforms.
