“…Indeed, as network representations are modular, they support any kind of coding tools and they facilitate the reconfiguration of a decoder by only modifying the topology of the network. This RVC decoding approach opens the way to new decoder functionalities which can change its decoding computation during the decoding process, as presented in [25].…”

International audienceThis paper demonstrates that it is possible to produce automatic, reconfigurable, and portable implementations of multimedia decoders onto platforms with the help of the MPEG Reconfigurable Video Coding (RVC) standard. MPEG RVC is a new formalism standardized by the MPEGconsortium used to specify multimedia decoders. It produces visual representations of decoder reference software, with the help of graphs that connect several coding tools from MPEG standards. The approach developed in this paper draws on Dataflow Process Networks to produce a Minimal and Canonical Representation (MCR) of \MPEG\ \RVC\ specifications. The \MCR\ makes it possible to form automatic and reconfigurable implementations of decoders which can match any actual platforms. The contribution is demonstrated on one case study where a generic decoder needs to process a multimedia content with the help of the \RVC\ specification of the decoder required to process it. The overall approach is tested on two decoders from MPEG, namely MPEG-4 part 2 Simple Profile and MPEG-4 part 10 Constrained Baseline Profile. The results validate the following benefits on the \MCR\ of decoders: compact representation, low overhead induced by its compilation, reconfiguration and multi-core abilities

“…An arbitrary decoder can be constructed at the receiver by selecting and interconnecting FU's from a tool library as specified by the encoder. Fully Configurable Video Coding (FCVC) concept [6] goes further by eliminating the need for a pre-defined library of tools at the receiver by transmitting the functionality of the tools themselves to the decoder using a Decoder Description syntax (DDS). Figure 1 shows the overview of the FCVC framework for implementing video decoders that can reconfigure, on-the-fly, to decisions made by an encoding engine about video coding format or algorithm.…”

“…Although many of these codecs share common and/or similar coding tools, there is currently no explicit way to exploit such commonalities at the level of the specification nor at the level of implementation. This problem grows as new standards are released and legacy formats continue to be supported, resulting in complex systems that are composed of multiformat algorithms and protocols with virtually unbounded complexities [1], [2]. Ideally, designers of video coding systems should be able to select arbitrary combinations of the available coding tools in a way that the combinations best match the requirements of each application but at the same time such customized applications remain into a standard framework that guarantees interoperability [3].…”

Reconfigurable Video Coding on Multicore T he current monolithic and lengthy scheme behind the standardization and the design of new video coding standards is becoming inappropriate to satisfy the dynamism and changing needs of the video coding community. Such scheme and specification formalism does not allow the clear commonalities between the different codecs to be shown, at the level of the specification nor at the level of the implementation. Such a problem is one of the main reasons for the typically long interval elapsing between the time a new idea is validated until it is implemented in consumer products as part of a worldwide standard. The analysis of this problem originated a new standard initiative within the International Organization for Standardization (ISO)/ International Electrotechnical Commission (IEC) Moving Pictures Experts Group (MPEG) committee, namely Reconfigurable Video Coding (RVC). The main idea is to develop a video coding standard that overcomes many shortcomings of the current standardization and specification process by updating and progressively incrementing a modular library of components. As the name implies, flexibility and reconfigurability are new attractive features of the RVC standard. Besides allowing for the definition of new codec algorithms, such features, as well as the dataflow-based specification formalism, open the way to define video coding standards that expressly target implementations on platforms with multiple cores. This article provides an overview of the main objectives of the new RVC standard, with an emphasis on the features that enable efficient implementation on platforms with multiple cores. A brief introduction to the methodologies that efficiently map RVC codec specifications to multicore platforms is accompanied with an example of the possible breakthroughs that are expected to occur in the design and deployment of multimedia services on multicore platforms.
