Publication Date:  2013-09-30 Views:  175 Downloads:  0

Issue Description

 Meeting up at RMCC on the terminal after the chairman and watch multi-screen applications of the various venues in the multi-screen display position specification is good, when viewing multi-screen applications, multi-screen display is always the same screen image, and all of are the first multi-screen multi-screen sub-picture

Alarm Information


Handling Process

  Because many meetings did not understand the cascade picture of the implementation process, so this phenomenon is normal, need to clear the following two questions:
1 For a cascaded conference subordinate MCU MCU can send all the way to the superior image, whether it is a single or multi-screen display can only be sent all the way to the image, if the subordinate is selected multi-screen multi-screen list is sent to the first meeting screen;
(2) lower the MCU multi-screen functionality is implemented on the superior MCU, MCU sent all the way to lower the image if it is a multi-screen in the master MCU to achieve superior multi-screen, because the lower the MCU only way to pass a multi-screen image so the image images are the same venue.

Root Cause

President through the terminal application and select multi-screen, multi-screen, you need to specify the location of each venue show is good, but the actual display of the multi-screen multi-screen images are the same, choose a different venue into a multi-screen display the first screen , the multi-screen display are the first screen through a list of IDO venue View venue belongs to a different MCU determines that the conference is cascaded meeting and the conference venue is only a MCU in the next meeting, while the MCU is subordinate MCU, when a meeting was held level even lower MCU only way to transfer images to a higher level MCU, while the multi-screen implementations are implemented on the main MCU, so the lower level all the way up the MCU transmitted image is divided into multi-screen, for lower compared to multi-screen venue to see the same image.
