Content Video Definition
Content Settings Select the transmission mode for the Content channel:
• Graphics — basic mode, intended for normal graphics
• Hi-res Graphics (AVC Only) — a higher bit rate intended for high
resolution graphic display
• Live Video (AVC Only) — Content channel displays live video
• Customized Content Rate (AVC Only) - manual definition of the
Conference Content Rate, mainly for cascading conferences.
Selection of a higher bit rate for the Content results in a lower bit rate
for the people channel.
For a detailed description of each of these options, see "Content
Settings” on page 4-7.

some endpoints support H.264.

• Content is shared using H.263 if a mix of H.263-supporting
and H.264-supporting endpoints are connected.
• Content is shared using H.264 if all connected endpoints have
H.264 capability.
• H.264 Cascade and SVC Optimized
• All Content is shared using the H.264 content protocol and is
optimized for use in Cascaded Conferences.
• H.264 HD (AVC only)

H.264 and HD Resolutions.
