Issue Description

Alarm Information
None
Handling Process
 Because we don’t fully understand the realization of multi screen, so this is normal phenomenon, we need to clarify two questions:
1. Junior MCU in cascade mode can send only one image channel to superior MCU, no mater single image or multi screen. If the junior select multi screen, it will transmit the first meeting place in the multi screen list.
2. The multi screen function of junior MCU is realized on superior MCU, because junior MCU only transmit one channel, so the multi screen show only one image.
Root Cause
After convene the conference on RMCC, terminal applies to be chairman and watch multi screen. Appoint each meeting place’s position on multi screen, and watch the screen, find out that multi screen still shows only one image, all other multi screen shows the first image. Find out that the MCUs of meeting places are different by checking IDO conference list, so, judge this conference is cascade conference, and there is only one meeting place under the MCU is in the conference, that MCU is junior MCU, there is only one image channel sent to superior MCU, and the multi image is realized on Main MCU, so the one channel image sent by junior is split to multi screen, junior meeting place will see the one image in multi screen.
