When transmitting keyboard, video, and mouse data, the most important component is video. That’s why, at G&D, we place special emphasis on developing the method our systems use to transmit visual content. Especially in mission-critical environments, where video information is essential for safety, monitoring, and rapid decision-making, reliability is indispensable. For this reason, we’ve developed our own video compression technology: bluedec™.
Challenge: Real-Time Video Data Without Quality Loss
KVM systems must operate reliably in control rooms:
- Safety: Any loss of images can affect critical decisions.
- Performance: Videos must be transmitted with zero latency, even with large data volumes.
- Resources: Bandwidth and infrastructure costs should remain as low as possible.
Balancing uncompressed transmission (best quality, high bandwidth) with compressed transmission (efficient, flexible, cost-effective) has always been a challenge.
The Solution: bluedec™ Video Compression
With bluedec™, G&D has developed a proprietary, multi-stage compression logic that transmits visual content efficiently and reliably.
How it works:
- Cross-frame analysis: Multiple frames are analyzed simultaneously to prevent image loss.
- Lower bandwidth requirements: Stable transmission starting at 3 Gbit/s, 1 Gbit/s, or even less.
- Pixel-perfect: Exact image representation for precise decision-making.
Compressed vs. Uncompressed Video Transmission
Compression refers to reducing data size by condensing or limiting information. This reduces the required bandwidth and shortens data transmission time.
Uncompressed systems transmit information transparently, pixel-perfect, and in real-time. Incoming data is output at the other end exactly as it was received. Uncompressed systems offer high bandwidth to forward video transparently from the computer’s graphics card to the monitor.
Compressed KVM systems can also provide very high video quality but offer numerous additional benefits. By compressing the video signal, these systems require less bandwidth and provide significant cost advantages for users. Their typically simpler cabling also often allows for greater flexibility in use.
Benefits at a Glance
With the new generation of bluedec™, users benefit from:
- Up to 30% higher efficiency with dynamic image content.
- 5–15% average bandwidth savings without compromising image quality.
- Compatibility: All existing and new G&D devices remain fully compatible.
- Flexibility: Simplified cabling and reduced infrastructure costs.
- Safety: Pixel-perfect, lossless transmission – essential for ATC environments and other mission-critical applications.
For product families VisionXS and VisionXS-IP, improvements can be applied with the latest firmware update.
The Perfect Solution for Control Room Applications in ATC
Pixel-perfect, lossless video compression is ideal for control room applications, where safety considerations often play a key role. Pixel-perfect video transmission ensures that what the air traffic controller sees on their monitor exactly matches the information output at the remote computer. In mission-critical environments like air traffic control, this is a very important aspect.
Conclusion: Smart Compression
Whether compressed or uncompressed, KVM systems must ensure the highest image quality. With bluedec™, we combine both: efficiency and top-notch visuals. The new generation proves that it can be even better – smoother, clearer, and more stable video transmission you can rely on in any situation.
