CHROMA KEY PRODUCTION SOLUTION

For Hardware Encoder–Based Real-Time Background Replacement

1. Overview

A hardware-driven chroma key pipeline engineered for professional environments where reliability, latency, and visual precision are mission-critical.
This solution transforms any shooting space into an operational virtual studio without increasing operator workload or relying on PC-based compositing.

1. What This Solution Solves

Most organizations using green screen setups face these problems:

• Background reflections causing poor edges

• Noise from low-end software keying

• Frame delay caused by GPU-rendered pipelines

• PC-based instability in 24/7 production

• Inconsistent results due to operator variations
   

2. Solution Architecture

Layer 1 — Acquisition

• SDI/HDMI cameras

• Controlled lighting on subject

• Non-reflective green/blue matte background
   

Layer 2 — Hardware Key Processing

The embedded chroma key module performs:

• Signal analysis

• Real-time color isolation

• Edge contour mapping

• Spill-suppression rewriting

• Sub-pixel soft blending

• Temporal noise filtering

Layer 3 — Background Composition

Supports:

• Static virtual sets

• Branded corporate backdrops

• Animated loops

• Multi-layer overlays (logo, lower-third, titles)

Layer 4 — Delivery

• SDI/HDMI out

• RTMP/RTSP/SRT/NDI streaming

• Local or network storage recording

• Integration with switchers / lecture capture systems
   

3. Why Hardware Keying Wins

(1) Deterministic Performance

Processing is performed on a dedicated silicon path —
no frame drops, no FPS fluctuations, no CPU/GPU bottlenecks, ideal for hospitals, universities, and broadcast studios.
 

(2) Consistent Color Math

Hardware always produces the same result →
no “today’s key looks different than yesterday's.”
 

(3) No Operator Skill Required

Once calibrated, even non-technical staff can go live.
This is extremely valuable for medical teaching, government livestreams, enterprise townhalls, and education centers.
 

(4) 24/7 Stability

PC-based VFX tools crash.
Hardware pipelines won't.

 

4. Application Scenarios

Education / Lecture Capture

Replace backgrounds with slides, lab diagrams, or campus-branded sets; produce clean, consistent teaching content regardless of the environment.

Corporate Virtual Studio

Executives appear in front of branded environments, analyst reports, animated corporate assets — with broadcast clarity.

Medical Training

Operate in controlled OR rooms while presenting procedure notes, imaging, or diagrams directly behind instructors.

Live Streaming & Event Production

Instant studio setup anywhere; deliver virtual sets without PC rendering.
