Biography

Prof. Dr. Susanto Rahardja

 

Susanto Rahardja received his B.Eng. degree from the National University of Singapore, and M.Eng. and Ph.D. degrees from the Nanyang Technological University (NTU, Singapore), all in Electrical & Electronic Engineering. In 1996, he joined the Centre for Signal Processing (NTU) as a research engineer and was appointed Assistant Director of the Centre for Signal Processing in 2001. Dr Rahardja is now the Director of Media Division at the Institute for Infocomm Research (since 2002), where he currently oversees and leads more than 100 full-time researchers in a broad range of media related research that cover areas in Signal Processing (audio coding, video/image processing), Media Analysis (text/speech, image, video), Media Security (biometrics, computer vision and surveillance) and Sensor Networks. His research interests are in Audio/Video Signal Processing, Spread Spectrum and Multi-user Detection Techniques for CDMA Applications, Digital Signal Processing Algorithms and Implementations, Logic Synthesis, of which he has more than 180 publications in internationally refereed journals and conferences.
Dr Rahardja is also an Associate Professor at the School of Electrical and Electronic Engineering in NTU and a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE). He was the recipient of the IEE Hartree Premium Award for the best journal paper published in IEE Proceedings in 2002. This is an annual award by the Council of IEE which recognizes outstanding papers published in IEE Proceedings on Computers and Digital Techniques. In 2003, Dr Rahardja received the prestigious Tan Kah Kee Young Inventors’ Gold award in the Open Category, for his contributions on scalable to lossless audio compression technology.
In 2002, Dr Rahardja actively participated in the international ISO/IEC JTC1/SC29/WG11 (Moving Picture Expert Group, or MPEG). He is an invited council member of the Information Technology Standards Committee (ITSC) since 2004. He is known for leading his team in propagating their innovative brainchild, Advanced Audio Zip, to MPEG international standards, where it was adopted as Reference Model 0 (RM0) in MPEG-4 Scalable to Lossless System (SLS), in July 2003. This was subsequently published as an international standard in June 2006 (ISO/IEC 14496-3:2005/Amd.3:2006). This is the first and only lossless audio technology with scalable capabilities and backward compatibility that was standardized in the world. At the same time, he led the team to develop an adaptive predictor technology for the audio lossless codec which was incorporated in the MPEG-4 Audio Lossless System (ALS) under the high performance profile (ISO/IEC 14496-3:2005/Amd.2:2006). In recognition of his significant contributions to the national standardization program, Dr Rahardja was awarded the Standards Council Merit Award by SPRING Singapore in 2006.
Dr Rahardja has served in several boards, advisory and technical committees in various IEEE and SPIE related professional activities in the areas of multimedia. He is elected members of the Technical Committee of the Visual Signal Processing and Communications, Circuits and Systems for Communications and Multimedia Systems and Applications of the IEEE Circuits & Systems Society. He is currently serving as Associate Editor for IEEE Transactions on Audio, Speech and Language Processing and the Journal of Visual Communication and Image Representation. He serves as the Conference Chair of Multimedia Systems and Applications at SPIE OpticsEast Symposium from 2006 to 2007 as well as Symposium Co-chair of the IEEE International Symposium on Multiple-Valued Logic in 2006.
Back in Indonesia, Dr Rahardja co-founded the AMIK and STMIK Raharja Informatika (www.raharja.ac.id), a coeducational institute of higher learning located in Tangerang, which is the leading private research institution with an average student population of 2000. He is currently the honorary director of Raharja Research Centre. 

 

Abstract
High Definition–Advanced Audio Coding
 

The advancement of network access and storage technologies has gradually made traditional high-compression technologies less and less attractive. At the same time, users are requesting better and better service quality. This trend is also reflected in the area of audio coding where the lossless audio compression technology has attracted more and more attention recently. It is observed that many digital audio entertainment applications such as Internet music downloads and DVD audio, depends on media technology that enables the reduction or compression of audio data to a fraction of its original size while losing little or none of its fidelity. At one end, there is a sustained demand of audio compression technology that provides near transparent quality. At the other end, there is an increasing demand for a state-of-the-art technology that provides ultimate lossless compression for application such as digital archiving. In addition, a solution that provides audio fidelity continuity in varying bandwidth condition while optimizing the available traffic is necessary.

In this talk, I will introduce the MPEG-4 High Definition Advanced Audio Coding (HD-AAC) which includes a scalable audio coding solution that integrates state-of-the-art lossless audio coding, perceptual audio coding and fine granular scalable audio coding into a single coder framework. In addition to the above functionalities, the HD-AAC provides convenience of backward compatibility to MPEG Advanced Audio Coding (AAC). Unlike the current lossy and lossless audio compression technologies, the SLS is a one-stop solution that provides lossy compression technology that can be enhanced in very fine layers that achieves final lossless state. A ubiquitous solution that offers interoperability among those two technologies is provided which is ideal to serve both lossy and lossless compression marketplaces and that is envisaged to replace the current existing isolated and separate solutions.
