The document summarizes improvements made to the Video Conferencing (VIC) tool to support high definition video for access grids. Key points: 1) The updated VIC tool leverages existing open source resources like FFmpeg to incorporate modern video codecs like MPEG-4 and H.264, allowing for higher quality video streaming in HD resolutions. 2) It adds features for error resilience, efficient color conversion, scaling viewing windows, and full-screen snapshots not previously supported by VIC. 3) Performance tests show the MPEG-4 codec can achieve television quality at 1Mbps for 720x480 video streams, using less bandwidth than older codecs like H.261.
