LED UHD signage box with LED HDR picture technology


Streamlined UHD Content Delivery

Samsung’s LED UHD Signage Box (S-Box) condenses the delivery of content to a single, centralized device. The S-Box transmits UHD content across multiple LED displays without requiring external boxes or a splitter. By streaming content output, the S-Box helps businesses enjoy a faster activation.

A Brilliant and Realistic Picture

During content transmission, the S-Box applies LED HDR technology for more detailed text and imagery. The S-Box elevates peak brightness to nearly 2X higher than the standard LED specifications and optimizes gradation and brightness within each individual scene to prevent visual inconsistency.

Integrated Content and Device Management

The S-Box is compatible with Samsung’s MagicINFO platform, enabling businesses to create, schedule and deploy content across an entire display network. Beyond content management, users also can manage a range of displays simultaneously through MagicINFO, reducing costs and operational burden.

Live Events in Real Time

The S-Box provides a Live Mode option and it is suitable where livestream events are required, such as indoor sports. When in Live Mode, the S-Box enables the LED displays to deliver content in real time, minimizing a signal delay.

Brightness Optimized for Any Environment

The S-Box automatically adjusts LED brightness levels by detecting the quantity of external light via dimming sensor. This in turn enables LED signage to display content with optimal brightness, while reducing display operating expenses and power consumption.

Sounds and Video Synchronized Flawlessly

Digital Audio Out support is included in the S-Box. Video and audio signals are seamlessly coordinated for a smooth and fantastic viewing experience. With no need for other processing devices, the S-Box will save time and money.
