Associate Professor Christian Ritz, Associate Dean International, faculty of Engineering and Information Sciences, University of Wollongong, Australia(UOW), Information processing specialist, delivered a keynote lecture entitled “Advanced Signal and Information Processing: An enabling technology for today’s multimedia world” on June 20,2017 at 301 seminar room of National Engineering Research Center for E-Learning(NERCEL). The lecture was presided over by Professor Yu Xinguo, the Dean of Central China Normal University Wollongong Joint Institute (JI).  

Associate professor Ruiz explained the foundation, principle, method and application of signal processing, and new progress in this field in the lecture.  

Associate professor Ruiz introduced his research interests, and many research institutions which conducted the computer science and communication engineering related research in UOW. Subsequently, he presented a variety of common signals, and the key issues facing signal processing. He illustrated the key technology in the multimedia world: multimedia signal processing, including digital signal processing, data compression and human perception of multimedia, and respectively described four kinds of encoding: "speech encoding", "audio encoding", "image encoding" and "video encoding". These basic knowledges laid the foundation of the important application field sound felid of advanced audio signal processing in the lecture, through the multizone spatial audio sound field theory. He also showed the new research direction in the field of information processing: how to create quiet zone in a room using loudspeakers based on multizone spatial audio ideas.
