The video reaches the player a few seconds after it happens in the studio, and the delay grows on a slow connection or a crowded network. Betting windows are timed from the studio clock, so a bet placed at the last visible second can arrive after the window has closed and be rejected. Lowering the stream quality in the game settings usually shortens the delay, and a wired connection helps more than any setting inside the game.
Studios run many tables at once, each with its own dealer, cameras and a floor manager watching the room. Dealers work in shifts, so the face at a table changes every half hour or so without the game stopping. Several operators often share one studio and show the same table under their own branding, which is why two different sites can display an identical dealer and card shoe at once.
A dropped connection does not cancel a bet that the studio has already accepted. The round plays out without the player, and the result is settled as usual, so a winning hand is paid and a losing one is lost. In games that need decisions, such as blackjack, the rules set a default action for a player who does not respond in time. The help panel lists that default, and it is worth knowing before the first hand.
