Abstract in Undetermined

Video coding technology in the last 20 years

has evolved producing a variety of different and com-

plex algorithms and coding standards. So far the speci-

fication of such standards, and of the algorithms that

build them, has been done case by case providing

monolithic textual and reference software specifica-

tions in different forms and programming languages.

However, very little attention has been given to pro-

vide a specification formalism that explicitly presents

common components between standards, and the incre-

mental modifications of such monolithic standards. The

MPEG Reconfigurable Video Coding (RVC) frame-

work is a new ISO standard currently under its final stage of standardization, aiming at providing video

codec specifications at the level of library components

instead of monolithic algorithms. The new concept is to

be able to specify a decoder of an existing standard or

a completely new configuration that may better satisfy

application-specific constraints by selecting standard

components from a library of standard coding algo-

rithms. The possibility of dynamic configuration and

reconfiguration of codecs also requires new method-

ologies and new tools for describing the new bitstream

syntaxes and the parsers of such new codecs. The

RVC framework is based on the usage of a new actor/

dataflow oriented language called Cal for the specifi-

cation of the standard library and instantiation of the

RVC decoder model. This language has been specifi-

cally designed for modeling complex signal processing

systems. Cal dataflow models expose the intrinsic con-

currency of the algorithms by employing the notions

of actor programming and dataflow. The paper gives

an overview of the concepts and technologies building

the standard RVC framework and the non standard

tools supporting the RVC model from the instantiation

and simulation of the Cal model to software and/or

hardware code synthesis. (Less)
