Live dealing is enabled by video streaming. The site packs software on its platform that allows video to be transmitted in real-time. On their end, players looking to play a live dealer session select it from the site menu.
A good internet connection is required to enable the player to move at the speed of the game. Many sites allow players to chat with the house via text.
This software also takes into consideration occurrences like interruption during gameplay. In such an event, most houses treat a player as if they did not take part in that round unless bets had already been placed.
