Live Casino Streaming: Uptime and Latency

Live dealer games are a large part of online casinos: real croupiers dealing blackjack, spinning roulette wheels and running game shows from a studio, streamed to players who bet from their phones. Behind the scenes, live casino is a demanding hosting problem, because the video, the betting window and the game result have to stay in step for thousands of players at once.

Why Latency Matters

Latency is the delay between something happening in the studio and the player seeing it. In ordinary streaming, a delay of twenty or thirty seconds is barely noticed. At a live roulette table it is a problem: the betting window has to close before the ball drops, and every player must see the same moment. Live casino providers therefore aim for a delay of a few seconds at most, which rules out the standard settings of many streaming tools.

How Low-Latency Streaming Works

Studios encode several video streams at different qualities and send them to a network of media servers close to players. Low-latency protocols, such as WebRTC or low-latency variants of HLS and DASH, keep the delay down, while the player’s app switches quality as the connection changes. The game data, including bets, timers and results, usually travels separately over a fast messaging connection, so that a video hiccup does not lose a bet.

Uptime: Minutes Matter

A table that goes dark in the middle of a round creates disputes and refunds. Live studios and the casinos that carry them build redundancy in at every step: backup encoders, two independent internet connections at the studio, several media server locations and automatic failover. Uptime targets are high, and a 99.9% figure that would satisfy a blog is not enough here.

Distance and Data Centres

Physics still applies: the further a player is from the media server, the longer the trip. Providers place servers near their main markets and, where a regulator requires it, inside particular countries. Distance also affects the betting platform itself, which is why operators think carefully about where their game servers and databases sit.

What Smaller Sites Can Learn

Most website owners will never stream a roulette table, but the same principles apply to any video on your site: use a specialist video host or CDN rather than serving large files from shared hosting, offer several quality levels, and keep the interactive parts of the page separate from the video so that one failure does not break everything. Our guide to types of web hosting explains where each option fits.
