What is the best way to organize the display of advertisements, info blocks, RTSP streams via PC to TV?

Question

VLC

Colleagues, help! How to set up live streaming from multiple cameras in playlist mode in VLC? So that they are broadcast, say, for 30 seconds and move to the next position?
Or maybe someone knows a simpler and more ingenious solution for such a task? (broadcast on TV in the sports center - image from IP cameras via RTSP, videos, images, possibly PP presentations and all in one "playlist".
