Graphics — basic mode, intended for normal graphics
Hi-res Graphics (AVC Only) — a higher bit rate intended for high
resolution graphic display

Content Protocol
H.263 (AVC only)
Content is shared using the H.263 protocol.
Use this option when most of the endpoints support H.263 and
some endpoints support H.264.
H.263 & H.264 Auto Selection (Default)
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)
Ensures high quality Content when most endpoints support
H.264 and HD Resolutions.
