Figure 1-2 SCOPIA XT1009/XT1209
The figure illustrates how the embedded MCU performs media processing for connected terminals
regardless of their location and handle multiple conferences simultaneously.
We recommend enabling the High Bandwidth Option (12Mbps) when using the embedded MCU. If
the High Bandwidth option is not enabled, the MCU will send out a lower resolution according to
the standard 4Mbps total bandwidth.
The embedded MCU can host Standard Definition (SD) and HD endpoints simultaneously. The
presence of SD endpoints does not affect the quality received by HD endpoints. SD endpoints will
receive SD video streams and HD endpoints will receive HD video streams. In the same way 4:3
and 16:9 video formats are included in the best possible way into the CP mosaic.
