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.
