Manish Dutta, Institute of Liver and Biliary Sciences Tele Conference Cart ‐ Solution We have developed a cart with following key components: 1. HD Video Conferencing: Vidyo Codec HD220 and router at Kyushu University is being used for multi party conference with remote participants. 2. Scalar: To convert video inputs from virtually all sources into format compatible with Vidyo for transmission. Key component of this general purpose cart. 3. Audio Mixer: To auto mix audio from multiple mics and Vidyo along with functionality of acoustic echo cancellation (AEC). Since complete Institute has centralised UPS supply, a dedicated UPS for cart was not provisioned.
