We describe the high quality collaborative environment that uses High Definition (HD) video to achieve near realistic perception of remote sites. The capture part, consisting of a HD camera, HD-SDI capture Centaurus card and UltraGrid software produces a 1.5\,Gbps UDP data stream of uncompressed HD video that is transferred over the 10GE network interface to the high speed IP network. The display part uses UltraGrid to down-sample the color depth and de-interlace the video, using either software solution or another Centaurus card to display the HD stream. Distribution to individual participants of the videoconference is achieved through user controlled UDP packet reflector based on the Active Element idea. The viability of this system has been demonstrated at the iGrid2005 conference for a three-way high quality videoconference among sites in Czech Republic, Louisiana and California.
