“…A MPEG-21 Bitstream Syntax Description Language (BSDL) schema describes the syntax of the bitstream. In [4,15], tools and methodologies for validation of BSDL syntaxes are described in full details as well as some examples of systematic procedures for the direct synthesis of syntax parsers in the CAL dataflow specification formalism.…”

With the rapid development of video coding technology, all kinds of video coding standards have been advanced in recent years with a variety of different and complex algorithms. They share common and/or similar coding tools, yet there is currently no explicit way to exploit such commonalities at the level of specifications or implementations. Reconfigurable video coding (RVC) is to develop a video coding standard that overcomes many shortcomings of current standardization and specification process by updating and progressively incrementing a modular library of components. In this paper, a hybrid decoder reconfiguration is instantiated in the RVC framework by grouping the coding tools from AVS-P7 and MPEG-4/AVC. Experimental results show that compared with MPEG-4/AVC baseline profile, the reconfigurable coding system reduces the computational complexity and guarantees the coding performance at low bit rate. Moreover, it enriches the RVC video tool library (VTL) by introducing the coding tools of AVS-P7, and also verifies the flexibility and re-configurability of RVC framework to meet the needs of different applications.

“…Nowadays, systems are required to be flexible and versatile, capable of supporting multiple codecs and profiles simultaneously, and to enable dynamic reconfiguration among them [13]. Fortunately, both standards and profiles, even migrating from one generation to another, tend to present commonalities that are exploitable both at specification level and at the implementation level to facilitate (re-)configurability.…”

Systems perception capabilities are fundamental to make modern interconnected systems smart and, in this context, video coding is certainly a key technology. Video coding standards have been traditionally based on monolithic specifications coupled to a fixed set of profiles, capable of implementing different sub-set of functionalities of the given reference standard. Standards and profiles typically offer different features and enable different trade-offs that make them suitable for different applications and scenarios. Nevertheless, keeping the pace with constantly evolving scenarios and user's needs, for example in terms of offered quality or consumed power, is not that simple, and has led to continuous releases/updates of standards and profiles.Ideally designers should be allowed, at design-time, to select and combine coding tools and profiles to optimally match the given requirements, while guaranteeing that customized applications are still interoperable. Nevertheless, monolithic specifications tend to hide parallelism and the dataflow nature of video coding algorithms that, on the contrary, can be successfully exploited to guarantee efficient implementations and to play with different trade-offs [8].To address these issues, related to codecs design and customization, designers have been called to conceive efficient design-time methodologies
