In a mixed CP and SVC conference, video resources are used according to the amount of
both AVC and SVC participants in the conference. The ratio of resources in a mixed
conference is one AVC HD (720p30) video resource to three SVC video resources, meaning
for each AVC HD video resource, three SVC video resources can be allocated.
For example, in a mixed AVC/SVC conference, 10 HD AVC ports and 30 SVC ports can be
used, maintaining ratio of one HD port to three SVC ports.
The following diagram illustrates the amount of AVC to SVC port resources that are used in
a mixed AVC/SVC conference:

During a SVC conference, each SVC-endpoint uses one video port. One SVC resource is
equivalent to one AVC CIF resource. When sharing content an additional video resource is
used.
