Jcdufourd is a Wikipedia pseudonym for Jean-Claude Dufourd, former Founder and Chief Scientist of Streamezzo, former Professor at Ecole Nationale Supérieure des Télécommunications (now called TELECOM ParisTech), ISO MPEG delegate since 1995, former MPEG Chairman of the Integration subgroup, editor of multiple MPEG documents such as MPEG-4 Conformance, MPEG-4 Reference Software and MPEG-4 LASeR. I contributed to the LASeR page, obviously.
My personal interests include singing, which is why I started the Alfred Wolfsohn and Roy Hart pages, at the request of some of the managers of the estate of these two people.
