Regarding CloudMCU multi-stream conferencing, the following description is incorrect?

Multi-stream hybrid conferencing supports AVC and SVC terminal access, supports cascading with fully adaptable conferences, and also supports cascading with multi-stream hybrid conferencing.

Pure SVC conferencing consumes more resources than AVC conferencing.

Compared to AVC conferencing, the codec is done by the terminal side in the SVC conferencing, and the NCU is only responsible for forwarding.

Multi-stream meetings do not support multi-screen broadcasting.
