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

It is necessary to develop ultra HIGH-SPEED Internet with the optical fiber networking 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.

DVoverIP DVoverIP

DVoverIP is the technology which developed to exchange high-quality DV data

  • n the IP network. The signal of the digital video can be delivered as it is

without deterioration.

DVTS was born by WIDE Project

WIDE is a project of research in Japan. It's organized in 1988, and being pulled by Prof. Murai of Keio University. URL: http://www.wide.ad.jp/
