Background of the Developm ent e-Japan Project （ （ （ Super-Fast Netw ork ） （ ） ） ） e-Japan Project （ （ Super-Fast Netw ork ） （ （ ） ） ） It is necessary to develop ultra HIGH-SPEED Internet with the optical fiber networking The TV conference is the only application of w hich adm itted by regional I ntranet The TV conference is the only application of w hich adm itted by regional I ntranet The net of running own business effective is used by DVTS TV conference system. The DVTS TV conferencing system is the best solution for the m unicipality. 2

W hat is DVoverI P? DV DV The image deterioration of the DV (Digital Video) is less than MPEG2 DVoverIP DVoverIP DVoverIP is the technology which developed to exchange high-quality DV data on the IP network. The signal of the digital video can be delivered as it is without deterioration. Comparison DV and MPEG-2 DVTS was born by WIDE Project Comparison DV MPEG-2 Bandwidth 30Mbps 2 ～ 30Mbps WIDE is a project of research in Japan. It's organized in 1988, Compression Rate 1 /5 1 /50 and being pulled by Prof. Murai of Keio University.

Multi Broadcasting ： ： ： Case Study ： The image conversation that synthesizes the reserved image of four terminals and delivers it can be offered by the reservation function in the Web base from among the terminal of two or more bases. Terminal Terminal WIDE Band Network Terminal Terminal Multi broadcasting server • A remote class and an interscholastic exchange are achieved with a high-quality two way comm unication. • The Movie is displayed on a large-scale display 8
