DEFINITION OF STANDARD:
Desktop video conferencing allows individuals at separate locations to see and hear each other, conduct meetings, and work together using interactive video and audio technology using a desktop computer. Images of documents can also be exchanged and users may work together on documents or projects. Desktop conferencing enables many of the functions available for enterprise systems (see 1000), without the sophisticated features. Desktop systems may operate in a LAN environment at the network speed or via data lines and ISDN (128 KBPS or 384 KBPS).

RATIONALE:
The selection of the VTEL product line for desktop video conferencing is consistent with the KTLN statewide video conferencing network. SmartStation is compatible with other VTEL systems through the H.320 standards for audio and video conferencing.

REVIEW CYCLE: 6 months
REVISION DATE: July1, 2003
EFFECTIVE DATE: December 11, 2001

Recommended Standard(s):
H.320
T.120 standard for data collaboration
Video Decoding: minimum 15 fps (frames per second)

Recommended Product(s):
VTel Galaxy PL
Polycom ViaVideo
Accord H.323 MGC-100

Justification:
At this time, desktop video conferencing is being tested in pilot applications using ISDN lines and the data network.

Technical Considerations:
Because of LAN bandwidth considerations, departments considering desktop video should consider ISDN with a 384 Kbps connection. ISDN requires an ISDN modem for dialup networking at 384 Kbps.
