There are none that I would call standard from an officiating point of view. We go over this with the TV guys before the game and they are usually very simple. Usually they are on the field when they want you to wait and they are giving a signal and getting off the field when they are back from commercial. I would not worry about it as you have a head set and will know what the director wants and make that clear with the crew. But no signals that are in the rules that I am aware of.
