Streaming a LIVE ONLINE QUIZ;

 I am doing an ONLINE quiz in acouple of days,

Only the participants( Teams) (about 6 teams of 2 each .) and  Scorer and Quiz master  will be visible on screen

However I would like the supporters of the respective teams to be able to view the quiz.

1) How  can this be done? Can we do a Live Streaming?

2) If  i add in NON PARTICIPANTS   Can I  mute their audio and turn of their cameras ..

please respond
