Description (to be revised)The Access Grid, as a communication channel for users from remote sites, can give researc
hers and scientists in both Korea and Japan a seamless and immersive collaboration environment. With this project, we want to explore the potential of Access Grid in supporting collaborative research between two countries. To realize it, we will collaborate to research ways to build low-cost Access Grid system (e.g. mini-AG or PIG) and to promote its deployment. Also, we will conduct a joint research to improve current AG systems to better support enhanced video/audio quality, interaction, security, and inter-operablity.
Expected Results (to be revised) - Provide a seamless colloaboration channel for researchers and scientists. - Promote the adoption of multicast technology over H-G link.
Required bandwidth - Dependent on the number of site, camera per site, video rates (normally full access node requires bandwidth around 1.5Mbps) - Multicast support

Immersiveness Enhancement for Access Grid via Stereo Immersiveness Enhancement for Access Grid via Stereo Video DeliveryVideo Delivery
For providing the immersiveness, we include the stereo video delivery functionality to EAG
Developing 3D video delivery module enables the reliable and real-time The developed system supports
o Reliable networking of real-time media with reliable transport via ARQ, FEC, and their hybrid
o Versatile display of stereo video in Left, Interlaced, Left & Right, and Above & Below views.

For the graphics side of 3D, EAG is being enhanced by supporting CG-based sharing in various communication architectures.
Combination of push repository in server memory and file repository method is implemented to support multi-user collaborative environment.
UIC EVL’s QUANTA is adopted as a baseline networking and data management module
VR software tools such as CAVELib or VR Juggler are also selected and utilized to build immersive 3D display.

Description We are planning to build a prototype version of ubiquitous environment utilizing Mobile IP and IEEE 802.11a/b (and other L2 media) connecting Fukuoka, JAPAN and Gw
angju, KOREA. On top of the built ubiquitous environment we will explore example applications such as u
ser tracking and IP mobile video streaming.
Expected Result In our joint effort, instead of trying to build hot spots, we will focus on building real ubiqui
tous environement with mobility and security support. We hope to let people in both countries to better locate each other and communicate ubiquitously.
Bandwidth Peak 100 Mbps / Average 10 Mbps
