Issue Description

During speed rate adaptation conference, sometimes, we can only see the image of the terminal that has the same speed, but can’t see other terminal that has different speed.

Alarm Information

None

Handling Process

We can view at the MCU side and find out that the MCU master only has 2 MVPA, in this conference, there have been 2 terminals which have different speed are seeing the video of conference place, so they are using two channels speed rate adaptation resource, so the MCU can’t provide more speed rate adaptation resource.

Root Cause

It’s not a fault, because MCU has the limited adaptation resource, it is determinate by how many adapted MVPA boards are there. The principle is: the device which gets the resource firstly can use it firstly; if the device can’t get the resource, it must wait until other device release the resource. This is the reason why we can’t see other terminal that has different speed.
