VNS Video-Over-IP Guidelines

Using H.264 H.264 is an improved video compression algorithm.  The H.264 encoding technique significantly improves the quality of video to allow for lower bandwidth usage.  Typically we have seen that using the H.264 standard at 128 Kbps provides a video quality that approaches the quality of an H.263 call at 384 Kbps.  The ITS Video bridge is capable of providing H.264 service with release 7.0.  To reduce bandwidth usage a client may choose to purchase a video system capable of H.264 and launch a conference that consumes less bandwidth.  This will reduce the overall traffic on your network allowing more bandwidth to data traffic.  H.264 may be used at 384 Kbps to improve the overall video quality. Most major manufacturers of video conferencing systems have employed H.264 in some form.  ITS Video Network Services has tested both Polycom and Tandberg endpoints using H.264. Some issues have been discovered and documented in a matrix.  Specific call setup procedures when launching H.264 videoconferences may be required for each make and model.  Call ITS Video Network Services if issues arise while using H.264.
