Video Session Select the appropriate Video Session:
Video Switching - To set a conference in which all
the participants use the same video and audio
formats, by setting the communication parameters to
the common capabilities. Whenever a participant
starts to speak, he/she appears on all screens as the
conference is a voice activated video switching
conference. All participants view the participant who
is the speaker. Up to 16 or 30 participants (if at least
one Audio Bridge is set to 1/30) can take part in a
Video Switching conference using the standard
Audio card. Up to 100 participants at 128Kbps can
take part in a conference running on the Audio+
card.
Transcoding - To set a conference in which
participants use different video, audio and data
formats, maintaining the highest video and audio
capability each participant can achieve with his/her
codec. Like Video Switching, the current speaker is
displayed on all terminals.
Transcoding is performed on the following:
• Line rate
• Audio algorithm
• Video format
• Frame rate
• Restricted/non-restricted
• Bonding/non-bonding
• Different data rates
Continuous Presence (CP) - A Continuous
Presence conference is a conference in which
several participants can be viewed simultaneously.
Each participant uses their own codec capabilities,
thus maintaining the highest video, audio and data
capability that can be achieved.
