Video Protocol | H264* - H.264* incorporates DCT (H.263) |
(con’t) | compression principles, but is provided at half the |
| bit rate. H.264* provides CIF/4CIF video using low |
| bit rates and implements a fixed video rate when |
| the video stream of the endpoint becomes active |
| ("people"). The endpoint that supports H.264* is |
| iPower. |
| H264 - The H.264 standard provides better |
| compression of video images in lower line rate |
| connections and is part of the Highest Common |
| mechanism in Video Switching conferences. |
| When the conference line rate is up to 384 Kbps, |
| and the Video Protocol is set to Auto (in both VSW |
| and CP conferences) the system tries to connect |
| the participant using H.264 video protocol first. |
| Only if the endpoint does not support H.264, the |
| system tries to connect the participant using H.263 |
| or H.261. |
| When H.264 is selected, the Video Format is |
| disabled and set to Auto. |
| Notes: |
| • When selecting the H.261 or H.263, the system |
| regards it as a fixed format and disables the |
| dynamic adjustment of the highest common |
| video. |
| • The dynamic adjustment of the video protocol |
| applies only to H.320 (ISDN) participants. |
| The dynamic adjustment of the video protocol |
| supports only 30 frames per second in CIF format. |
| All other H.263 capabilities are disabled. |
