Game Control Unit (GCU)

A small device attached to each live table that encodes the video feed and manages the game data, often described as the heart of a live table.

Definition

The Game Control Unit (GCU) is a compact hardware device fitted to every live-casino table whose job is to encode the table's video and to gather and transmit its game data — working with the cameras, wheel sensors, and OCR so that video and results are captured and broadcast together. It is frequently described as the most important piece of equipment on a live table, because without it the table's feed and data cannot reach the platform. Originally developed to run roulette tables, the concept now underpins the whole studio: each table's GCU digitises its physical events and streams them, letting one studio broadcast hundreds of tables reliably. It is core infrastructure — invisible to players but essential to fairness and delivery.

Worked example

Beneath a live blackjack table sits a small GCU wired to the cameras and card sensors; it encodes the video and packages each dealt card's data, sending both to the streaming platform so every player sees the game and has their bets settled from the same synchronised source.

Why it matters

The GCU is the piece of kit that literally makes a live table broadcastable, so it is central to any technical understanding of live casino. For professionals it is a key consideration in studio design, redundancy, and integrity — a table's fairness and uptime depend on this device working reliably.
