Abstract
Video coding technology has evolved in the past years into a variety of different and complex algorithms So far the specifications of such standard algorithms have been done case by case providing monolithic textual and reference software specifications but without paying any attention to the possibility of further improvements of such monolithic standards The MPEG Reconfigurable Video Coding RVC framework is a new ISO/IEC standard currently under its final stage of development aiming at providing video codec specifications at the level of coding tools instead of monolithic descriptions The possibility to select a subset of standard video coding algorithms to specify a decoder that satisfies application specific constraints is very attractive However such possibility to reconfigure codecs requires systematic procedures and tools capable of describing the new bitstream syntaxes of such new codecs Moreover it becomes also necessary to generate the associated parsers capable of parsing the new bitstreams This paper further explains the problem and describes the technologies used to describe new bitstream syntaxes Additionally the paper describes the methodologies and the tools for the validation of bitstream syntaxes descriptions as well as a systematic procedure for automatically synthesizing parsers from the bitstream descriptions
