From the player’s side, a live dealer table looks simple: a dealer, a table, a few cards or a wheel, and a video window on a phone or laptop. Behind that window sits a small broadcast operation that has more in common with a television studio than with a typical web app, and it is a useful case study in how physical events become reliable digital information.
The setup has been part of the Ontario market for a while. When Evolution went live with the Ontario Lottery and Gaming Corporation in October 2021, its press release said Evolution’s Vancouver studio produced live casino services for OLG’s online site, with blackjack, roulette, and baccarat alongside RNG-based versions. In other words, a table running in British Columbia was being delivered to players in another province in real time. For players comparing real money casinos in Ontario, it is a useful reminder that what looks like a local game room is really a networked production.
Inside the studio
Evolution’s live casino history describes a shift from a single grainy webcam to multiple high-definition cameras, full-screen video, and studio features such as blue-screen (chroma key) technology and autocue systems that help dealers keep eye contact with players. Cards are barcoded, and dealers shuffle and change shoes in view, so players can see the process is open and the system can machine-read what was dealt. Camera angles are chosen so players can see the action from several perspectives, including close-up “squeeze” views of cards.
The key engineering idea is that the video and the game data travel together but are not the same thing. The video shows the dealer; the data says which card or number actually came up, so the player’s screen can update bets, results and balances accurately. In engineering terms, a control system sits between the table and the player and keeps the two in step, and that synchronisation is as important as picture quality. Evolution notes that latency, sound and video synchronisation became standard parts of the process.
Getting video to a browser
Once the table has produced video, it has to reach thousands of screens with as little delay as possible. Two technologies come up most often in discussions of low-delay streaming. WebRTC, as Mozilla’s developer documentation describes it, lets web applications capture and stream audio and video, and exchange arbitrary data, between browsers without needing plug-ins, and often without intermediary servers.
HTTP Live Streaming (HLS), defined in RFC 8216, takes a different approach: the stream is cut into media segments that a playlist describes, and the player downloads and plays them one after another while reloading the playlist to find new ones. Because HLS works in segments, the delay depends partly on their length, which is why interactive products tend to favour lower-delay approaches. Which combination a given provider uses is rarely published, so it is safest to treat these as the available tools rather than a description of any one live casino.
The resilience layer matters too. Evolution says its systems include an emergency mode that keeps games running when bandwidth drops by shrinking the video and enlarging the interface, and that HTML5 conversion improved performance across devices. Those details line up with what any streaming engineer would expect: adaptive quality, graceful degradation, and a lightweight front end.
Live versus RNG
It also helps to clarify the difference between the two kinds of casino games. A live table is a physical event, captured on camera and verified by equipment, with outcomes that come from real cards and a real wheel. An RNG game is software in which a random number generator determines the result and the visuals are computer-generated.
What Ontario regulators look at
The technology sits inside a regulated framework. The Alcohol and Gaming Commission of Ontario regulates the province’s igaming market, develops the Registrar’s Standards for Internet Gaming and monitors operators and games for compliance, while iGaming Ontario conducts and manages igaming offered through private operators.
The Registrar’s Standards set specific game integrity requirements for live dealer games: access to live dealer gaming supplies must be restricted to people with a business need, and operators must have controls to prevent game presenters from compromising game integrity. Equipment used in live dealer games that contains electronic components must also be certified by an independent testing laboratory registered with the Registrar. The regulator publishes its own breakdown of how responsibilities are split; see the AGCO’s explanation of how its role differs from iGaming Ontario’s, and players must be 19 or older to take part.
Where to go next
For developers, the most transferable lesson is how much work it takes to make a physical event trustworthy as data. If that interests you, the same mindset applies to parsing and validating messy feeds, which is the subject of terabytelabs’ guide to data softout4.v6 Python for developers.
For players, the takeaway is a little more practical. Live tables are entertainment, outcomes are never guaranteed, and it makes sense to set time and spending limits before you start and to use only operators on AGCO’s list of registered operators. If gambling stops feeling like fun, iGaming Ontario’s site has a Find Help section, and taking a break is always a fair option.
