Overview

Currently this technology is being evaluated for use on the desktop and to support the VCCS Commonwealth Conference Room. As the technology matures, Full Screen Desktop Video Conferencing (DVC) may become an alternative to the existing H.320 environment.

Full Screen (CIF) can operate at up to 30 fps. The video and audio quality depends on the available bandwidth within the LAN and Quality of Service (QOS) mechanism to ensure real-time delivery of the conference. The Client desktop should be dedicated to only used for DVC to ensure the best performance of the videoconference. This technology fits both the VCCS requirements for business quality and in the future classroom videoconferencing.

The Advanced Technology Unit is continuing the research and investigation of this technology and further improvements are needed before releasing this technology for general deployment. The technology is promising and progress is being made.

1. Pentium-class processor, 300 mhz or higher.
2. Windows 95/98 or NT (preferred).
3. One available PCI bus slot, must be bus mastered, for the codec board
4. 70mb+/- (estimated) of available hard disk for plug and play drivers, and application software.
5. 64mb (minimum) of RAM, 128 MB recommended.
6. SVGA or VGA monitor with mb video RAM.
7. PCI bus graphics subsystem, capable of displaying 16-bit high color mode.
8. Network Interface Card (10/100 Ethernet with 4mb cache).
9. Winsock 1.1 compliant TCP/IP protocol stack that supports Microsoft extensions.
