Keynote Speakers

Yoichiro Kawaguchi

Artist / Professor of The University of Tokyo.

Born in Tanegashima Island, Kagoshima Prefecture Japan in 1952. Kawaguchi major in 3D Computer Animation and graduated from Kyushu Institute of Design (current Kyushu University) in 1976. He received his Master of Fine Arts from Tokyo University of Education (current University of Tsukuba) in 1978. After teaching at University of Tsukuba as an associate professor until spring of 1998, he was promoted to a professor of The University of Tokyo in 1998. He has been working on Computer Graphics since 1975, and has been recognized as a pioneer and a world-wide authority of CG art by unique style using his ‘GROWTH Model’. ‘GROWTH Model’ is a Self-Organizing method to develop one’s formative algorithm of a complex life form.
Concurrently with development of CG which express nature’s beauty based on physical fundamentals, his recent interests are ‘The EGGY’ project 8K, Ultra HDTV project, creation of new tradition project, creation of artistic and primitive robot for planet explore, development of ‘Gemotion’(Gene, Growth + emotion) display, 3D Bumpy display which react emotion like living beings.

8K Ultra High Definition TV for Art

Prof. Kawaguchi will explore in his presentation the new paradigms of the 8k Ultra High Definition TV and its new possibilities for art. The Ultra HDTV system is very marvelous for Art. This system consists of an 8k horizontal spatial resolution and 60 frames per second temporal resolution. From the viewpoint of Art, this advanced development of 8K Ultra HDTV enable us to verify a wide variety of new possibilities.


Hideichi Tamegaya

Hideichi Tamegaya began introducing computer graphics (CG) technology in broadcasting program production in 1981. He has developed CG systems through many advanced program production. He designed a new production methodology concept, “Electronic Palette”, to integrate HDTV and digital technologies for the movie production. The concept has been presented to Hollywood and other motion picture industries. Joining Media International Corporation (MICO) in 1991, he has been providing technical consultation and support on domestic and international HDTV, CG and digital media technologies to NHK and other production teams filming HD programs. He made it possible to mount a HDTV camera on a space shuttle for the first time in the world in 1998. He has served on various research committees and councils of the Ministry of Internal Affairs and Communications, the Ministry of Economy, Trade and Industry, and the Ministry of Education, Culture, Sports, Science and Technology, and he is currently working for promotion and development of the digital content industry.

Tamegaya is a member of the following associations: the Association for Computing Machinery’ Special Interest Group on Computer Graphics (ACM-SIGGRARH), the Japan Society of Image Arts and Sciences, the Motion Picture and Television Engineering Society of Japan, the Institute of Image Information and Television Engineers and the Japan Virtual Reality Society

New image expression brought by the evolutions in media technology

Dr. Tamegaya will discuss in his presentation the extended media and the future of the digital content. In 1998, the world’s first HDTV camera was installed in the space shuttle. This camera made it possible for us to extend the production platform in space, 550km above sea level. The images through the HDTV camera could make us experience the same feeling as astronauts feel in space.

This “virtual presence in space” brings the same “Impression” as what people would get from the artistic expression. The evolution of the technologies extends the traditional media. The “Impression” is derived from new contents, which is created by this extended media. The people of the next generation, who grow up in the new media environment, can see the future media lifestyle in their imaginations.

Development of the High Frame Rate 3D System

Mr. Kuroki will explore on his presentation the advances in 240 fps single lens 3D camera, 240fps 4Kx2K projector and 240fps LCD display prototypes. These high frame rate equipments bring extremely high quality of motion. And the camera has advantages mainly as follows: 1) comfortable 3D image by no vergence-accommodation conflict, 2) simple and accurate control on zoom / focus of single lens, 3) with no polarized glasses, normal 2D image can be seen.

Cognitive Radios in TV Bands

The switchover to digital TV allied to the inefficiency inherent to fixed spectrum allocation characteristic of licensed regimen has urged authorities to reconsider traditional spectrum management policies. The Federal Communications Commission (FCC), in USA, and the Office of Communications (OfCom), in UK, responded by investigating the feasibility of having unlicensed cognitive radios accessing the licensed spectrum in an opportunistic way. Other regulatory bodies in european countries as well as the japanese Ministry of Internal Affairs and Communications (MIC) are following the same path and considering utilization of unlicensed cognitive radios in the licensed TV spectrum. In one hand, this approach takes advantage of a vast amount of under utilized TV spectrum that can bring tremendous benefits to our modern society by creating new services without the need to set aside new frequency bands. Needless to say, wireless equipment manufacturers and wireless service providers are, fiercely, supporting the new technology. On the other hand, the access of unlicensed devices to the TV spectrum, however, must be regulated. These devices must be restricted to access only unused TV spectrum in a given location and time, i.e., restricted to the TV White Space (TVWS), in order to prevent interference to digital TV users. Obviously, this move towards unlicensed use of licensed bands has faced strong opposition from broadcasters, therefore, making communications in TVWS even more challenging. This talk will address the issue of wireless communications in the TVWS. Introduction to cognitive radio technology, ongoing research topics in TVWS, standardization activities, benefits and challenges of the technology as well as regulations will be covered.

Seeking Optimal Granularity: Are We There Yet?

Computer architects have been seeking many kinds of parallelism. From SIMD to multi processors, there are many degree of granularity. However, it seems that many media processing algorithms do not completely match to multi-<stream|core|processor> architecture. This presentation considers the usage of multi-* architectures and proposes new architectural direction for media processing.
