Classroom lecture with 2 way participation between the lecturer and the students

My use case is as follows:

Stream a training video. Take questions from students thru a video feed. Take questions from students thru chat also.

It’s important to note that our hardware devices are streaming devices. This means that the content is streamed in a single direction. If your use case would require two-way communication and video, it would not be done native to streaming devices and would require conferencing type equipment to establish the communication(s)
