Now operators (sitting at home) can speak directly to players at the table. It functions just like a telephone or Skype. The voice is fully encypted. But the communication is one-way. It could be made two-way, but there isn’t much point to players speaking to the operator anyway, because a player talking to themselves at the table is rather suspicious. The communication is more so the players know accuracy and whatever is needed. Also if an operator is used, the player never needs to leave the table for anything.
Although the Hybrid can be used by single players, it is much better to have an operator watching the live video feed, and checking accuracy data from the comfort of home.
