To make it easy and safe for everyone because the hall (auditorium) in most of the building is not big enough for everyone to be inside. I suggest, it good to have video and audio with different channels at restaurants or most of the safety place so people have an option to listen live speech or live audio. Also safety concern, over allowable capacity in the hall (auditorium) incase of emergency.
