Tele Conference Cart ‐ Solution
We have developed a cart with following keycomponents:
1. HD Video Conferencing: Vidyo Codec HD220 androuter at Kyushu University is being used formulti party conference with remote participants.
2. Scalar: To convert video inputs from virtually allsources into format compatible with Vidyo fortransmission. Key component of this generalpurpose cart.
3. Audio Mixer: To auto mix audio from multiplemics and Vidyo along with functionality ofacoustic echo cancellation (AEC).
Since complete Institute has centralised UPS supply, a dedicated UPS for cart was not provisioned.
