What technologies are used in Live-Casino
1) Studio and production: hardware in front of the camera
Cameras. PTZ cameras with remote control, global shutter and autofocus; separate 4K/HD angles: general plan, close-up of the table, macro on the wheel/cards.
Optics. Fast zooms for clean close-ups; polarizing filters against glare on chips and lacquered field.
Light. Permanent CRI 95 + (panels/softboxes), emphasis on desk surface and dealer face; anti-flicker for frame rate.
Sound. Shotgan microphones and noise canceling loops; automatic mix without echo.
Scene. Real scenery or chromakey (chroma key) with virtual halls; acoustic panels to drown out adjacent tables.
2) Gaming table: sensors and smart peripherals
Roulette. Industrial wheels with balance calibration; inductive/optical sensors for fixing a winning pocket, speed encoders.
Maps. Auto-scaffolds, protected card dispensers, marks for machine reading of denominations.
Betting fields. Tags/anchors to accurately match clicks to the actual layout.
Anti-tamper. Seals, equipment integrity control, tamper-evident logging.
3) Computer Vision и OCR
Recognition. OCR reads card values; CV determines the position of the ball, tokens, dealer gestures.
Models. Convolutional networks/transformers, GPU/Edge TPU optimization, INT8 quantization for latency.
Fusion circuit. The result is confirmed via two channels - video + sensor; in case of discrepancy → automatic void and return of bets.
Anticollection. Tracking abnormal patterns, "ghost" chips, belated movements.
4) Game server and round logic
Orchestration. Bet Open → Bet Close → Event → Settlement → Next Round.
Juxtaposition. Client clicks (coordinates/denomination) are mapped to field zones; all operations are signed by transaction IDs.
Settlement. Coefficient tables, multipliers, side rates; idempotency of payments.
Timing. Unified timeline (NTP/PTP) for video stream and game server events.
5) Video stack and delivery
Codecs. H.264/AVC as base profile HEVC/VP9 - to save bitrate; cylinders of bitrates under coronavirus.
Protocols.
WebRTC - ultra-low latency (≈0. 5–2. 0 c) for live bets.
LL-HLS/DASH - scalable backup delivery under high load.
SRT/RTMP - as an internal link "studio → head station."
CDN/Edge. Distribution of flows to near nodes; geo-pinning to shorten RTT.
ABR и FEC. Adaptive bitrate + Forward Error Correction and ARQ repeats for robustness.
DRM/Protection. SRTP/DTLS/TLS, segment signatures, access tokens, stream protection.
6) Client (web/app) and UI
Betting interface. Canvas/WebGL overlays, large clickable zones, fast chip presets, repeat/double/clear.
Synchronization. Local timers are synchronized with the server; "Guard time" cuts off late clicks.
Accessibility. Contrasting themes, large elements, hotkeys, status scoring.
Chat. Moderation, toxicity filters, preset tempo cues.
7) Reliability and redundancy
N+1. Duplicates of cameras, encoders, network paths and power supply (UPS/generators).
Failover. Auto-switch source, hold round status; when criticized - correct void.
Observability. Metrics and logs: Prometheus/Grafana dashboards, tracing, delay alerts, jitter, dropped frames.
Chaos tests. Injection of network/hardware failures out of prime time, on-call training.
8) Safety and anti-fraud
Network. Segmentation of studio/production networks, Zero-Trust to services, MFA/SSO for staff.
Client signals. Device fingerprint, behavioral biometrics, analysis of frequent IP shifts and VPN/proxy pools.
Payments. BIN-geo, 3-D Secure/OOB-confirmations, behavioral scoring before withdrawal.
Chat/community. Antispam, stop list of words, rate-limit cues.
9) Regulatory and reporting
Certification. Labs check equipment, processes and mathematics; periodic inspections.
Logs/WORM. Non-rewritable storage of rounds, hash chains, storage of video archives according to the regulator's deadlines.
API gateways. Machine-readable reporting on GGR/rounds/incidents; RG events (self-exclusion, limits).
Privacy. PII minimization, on-disk and in-channel encryption, data subject rights (GDPR and analogs).
10) Scaling and DevOps
Containers. Kubernetes/Service Mesh for game server autoscaling and WebRTC signaling.
Caching. Edge cache for static assets and UI; hot pay tables in memory.
Traffic figure. Automatic prime time dilution, room limits, CDN preheating.
Canary/Blue-Green. Non-stop client and server updates without the risk of "interrupting the round."
11) Key Quality Metrics (QoE/QoS)
Average/95th delay percentile (target is sub-2s on WebRTC).
Betting Window Conversion.
Dropped Frames/Rebuffer Rate (picture stability).
Reconnect Rate и Time-to-First-Frame.
Dispute Rate (percentage of disputed rounds, target → ~ 0).
First-Time Withdrawal Success (indirectly - trust and correct KYC).
12) What does it give the player and business
Player: visible honesty (physical result + sensor confirmation), understandable timers, instant calculation and stable picture even on a mobile network.
Operator: higher retention, less disputes, predicted SLAs, rich telemetry for improvements, compliance with regulator requirements.
Player checklist
1. Check that the stream starts quickly and without friezes (preferably 10-15 Mbps).
2. Check the timer delay and video (bet close should be ahead of event).
3. Read the void/returns policy and table limits.
4. Pass KYC early; Use the same I/O method.
Operator/Studio Checklist
1. WebRTC signaling with LL-HLS reserve; edge-CDNs in target regions.
2. Double result fixation (CV/OCR + sensor), automatic conflict-resolver.
3. Real-time latency monitoring and Betting Window Conversion.
4. N + 1 on cameras/encoders/power, regular failover drills.
5. Transparent RG policies, WORM log storage and ready-made incident reports.
Live-Casino works at the junction of TV production, real hardware of the table and fintech infrastructure. Cameras and light give a readable picture, sensors and CV give a verifiable result, WebRTC/LL-HLS and CDN give a low latency, and the game server and reporting give transparent payments and compliance with the law. A strong technology stack translates directly into player confidence, less controversy, and a sustainable product economy.
