Explanation:
The integrated video conferencing services use the same DSP resources on PVDM3s that are used for
widely deployed ISR G2 voice capabilities. These modules, in conjunction with Cisco IOS Software,
perform audio and video mixing, video transcoding for certain resolutions, and other functions for
video endpoints. PVDM3 modules support flexible media resources and conference profile
management to maximize capacity with predictable end-user experiences. Both homogenous and
heterogonous video conferences are supported. A homogenous conference refers to one in which
participants connect to the ISR G2 with devices that support the same video format attributes (for
example, the same codec, resolution, frame rate, and bit rate). A heterogeneous conference refers
to one in which participants can connect to a conference bridge with devices that support different
video format attributes. Each conference allows 4-, 8-, or 16-party participants.
