Reconfigurable Media Coding: A New Specification Model for Multimedia Coders

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 designer to produce the codec supporting any desired functionality as well as any desired trade-off between compression performance and implementation complexity. Currently, interoperability demands that this selection process be hard-wired into the normative descriptions of the codec, or… Show more

“…Reading a macroblock from the frame buffer takes 10 + (384/4) = 106 cycles, thus reading three macroblocks takes 318 cycles. 6 This has to be done once per macroblock of data, or once every 384 samples-consequently, we spend 318/384 = 0.83 cycles per sample reading data from the frame buffer, which conveniently meets our requirements. Note that reading the next set of macroblocks can be concurrent with the processing related to the current search window.…”

“…Adopting dataflow as the fundamental design methodology, they have decided to use the Cal actor language [3] for building the modules, which are composed using an XML format called FNL [4] (FU Network Language formerly DDL [5,6]). …”

“…The RVC initiative exploits the reuse of obvious commonalties among different MPEG standards and their possible extensions using appropriate higher level formalisms. Thus the objective of the RVC standard is to describe current and future codecs in a way that makes such commonalities explicit, reducing the implementation burden for device vendors [2]. In order to achieve this objective, RVC suggests simplifying the specification of new coding tools by reusing components of previous standards instead of defining new ones.…”
