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.

The Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3 (ISR G2 PVDM3) can support video conferencing using the Cisco Unified Communications Manager (CUCM) or Cisco Unified Communications Manager Express (CUCME). The number of per-session video conference participants that can be supported depends on the number of digital signal processor (DSP) resources available on the router. The DSP resources are used for video codec processing, which is required for video conferencing.
The DSP resources on the ISR G2 PVDM3 are available in different densities, depending on the type of PVDM3 module installed in the router. The PVDM3 modules are inserted into the PVDM slots on the router, and each module contains a certain number of DSPs.
The valid per-session video conference participants supported on the ISR G2 PVDM3 with different PVDM3 module densities are as follows:
PVDM3-16: This module contains 16 DSPs and can support up to 3 per-session video conference participants.
PVDM3-32: This module contains 32 DSPs and can support up to 4 per-session video conference participants.
PVDM3-64: This module contains 64 DSPs and can support up to 6 per-session video conference participants.
PVDM3-128: This module contains 128 DSPs and can support up to 8 per-session video conference participants.
PVDM3-192: This module contains 192 DSPs and can support up to 9 per-session video conference participants.
PVDM3-256: This module contains 256 DSPs and can support up to 12 per-session video conference participants.
PVDM3-512: This module contains 512 DSPs and can support up to 16 per-session video conference participants.
Therefore, the valid per-session video conference participants supported on the ISR G2 PVDM3 with packet voice and video digital signal processor 3 are options A (3), B (4), and C (6).
