Video Protocol  | Select the Video compression standard:  | 
  | Auto - Select this option to use the conference’s  | 
  | Video Protocol settings and enable the dynamic  | 
  | adjustment of the Video Protocol in Video Switching  | 
  | conferences.  | 
  | H261 – The video compression standard mandatory  | 
  | to all codecs.  | 
  | H263 - A compression standard that provides  | 
  | improved video quality at a line rate lower than 384  | 
  | Kbps. This standard is not supported by all codecs.  | 
  | H264 - By default, the Video Protocol is set to Auto.  | 
  | When H.264 is selected as the Video Protocol, the  | 
  | participants are “forced” to use the H.264 video  | 
  | protocol. Endpoints that do not have H.264 video  | 
  | protocol capabilities connect as Secondary.  | 
  | Notes:  | 
  | • When the Video Protocol field in the Conference  | 
  | Properties – Settings is set to Auto it overrides  | 
  | the Video Protocol settings in the Participant  | 
  | Properties – Advanced window as the dynamic  | 
  | mode is enabled and the video settings are forced  | 
  | by the MCU.  | 
  | • If the Video Protocol is set to H.263 and the  | 
  | endpoint does not support it, the participant will  | 
  | be connected as Secondary (Audio only).  |
