S902

S902

4K Multi-Source Composition Processor

Create flexible UHD layouts from up to four HDMI sources with free window positioning, seamless switching, layering and dual 4K outputs.

S902 combines independent video sources into a controlled multi-window canvas before the signal reaches a large display, LED controller, projection processor, recorder or monitoring system.

What S902 Does

S902 turns up to four independent UHD sources into a configurable display canvas. Each source can be assigned to a window, resized, cropped, positioned and layered independently, allowing operators to create different presentation modes without rebuilding the source content.

Flexible Multi-Window Composition

Position Each Source Where It Is Needed

Display up to four windows simultaneously and freely control their size, position, cropping and aspect ratio.

Each window can select any HDMI input, and the same source can also be assigned to multiple windows when required.

Layering & Alpha Blending

Build Layered Visual Compositions

Windows can overlap with independently defined layer priority, allowing video, graphics and live information to be arranged as part of one visual composition.

Alpha blending adds adjustable transparency where content needs to remain visible through overlapping layers.

S902 also supports a programmable background using a solid colour, captured image or uploaded graphic.

Seamless Layout Switching

Change Presentation Modes Without Rebuilding the Content

Move between single-source, multi-window and customized layouts using saved profiles instead of reconfiguring the source devices.

S902 includes system layout presets and supports up to 20 custom profiles, allowing complete presentation modes to be recalled through the front panel, remote control, PC tool or external control system.

Transition effects including seamless switching, fade, dissolve and wipe can be applied when changing sources or presentation modes.

Dual UHD Output Routing

Send the Composition to Two 4K Destinations

Two HDMI 2.0 outputs allow the processed content to be sent simultaneously to the main display and a secondary destination such as a confidence monitor, recorder or downstream display processor.

Windows can be assigned to Output 1, Output 2 or both, providing additional routing flexibility within the system.

Video Performance

S902 is designed for professional UHD signal workflows, preserving image detail while processing several sources simultaneously through dedicated hardware.

4K60

UHD Input & Output

Four HDMI 2.0 inputs and two HDMI 2.0 outputs support video formats up to 4096 × 2160 @ 60 Hz.

4:4:4

Full-Chroma Processing

Support for RGB / YUV 4:4:4 preserves text, interface graphics and fine visual detail in professional presentation and visualization applications.

10-bit

High-Quality Processing

Internal 10-bit video processing provides high-quality scaling and image adjustment throughout the multi-window composition pipeline.

1–2 FRAMES

Low-Latency Hardware Processing

Dedicated hardware processing keeps latency to approximately 1–2 frames, depending on system configuration and video format.

Engineering Features

System-level functions make S902 suitable for fixed AV installations where layouts need to remain repeatable and controllable independently from the source computers.

20 Profile Presets

Save complete window layouts, source assignments and related settings for fast recall during operation.

Independent Picture & Color Adjustment

Adjust picture and color settings independently by input source and window, making it easier to visually match content from different cameras, PCs and media players within the same multi-window composition.

Flexible Audio Routing

Embedded HDMI audio can be selected for the HDMI outputs, with additional SPDIF and analogue audio outputs for system integration.

External Control

Integrate GeoBox functions with third-party control systems for remote operation, preset recall and system automation.

Live & Edit

Prepare or modify another profile through the SCT control environment while the current profile remains on screen.

SCT PC Tool & WebUI

Configure source assignment, window geometry, priority, background and system settings from a PC for faster commissioning and operation.

Typical System Architecture

Separate the Source Canvas from the Display Layout

S902 is normally positioned after the source devices and before the physical display-processing stage. Its responsibility is to create the multi-source canvas; downstream equipment then adapts that canvas to the final display system when required.

Choose S902 When

  • You need several independent HDMI sources to appear within one controlled UHD presentation canvas.
  • You want windows to be freely positioned, resized, cropped and layered rather than restricted to fixed quad-view layouts.
  • Seamless source switching, transition effects or alpha-blended visual layers are required.
  • Different presentation modes need to be saved and recalled without rebuilding layouts on the source computers.
  • A second HDMI destination is useful for monitoring, recording or downstream processing.
  • The physical display processing can be handled separately by the LED controller, projector system or another GeoBox processor.

When to Use G901

Need ultra wide or custom output resolution instead of Free Multi-Source Composition?

Choose G901

Choose G901 when the system does not require flexible four-source multi-window composition, but instead needs image cropping, scaling, rotation, output timing control or adaptation of a source to a specific display configuration.

Best for: image cropping and scaling, portrait display rotation, custom output timing and display-side signal processing.

SYSTEM EXTENSION

Extend S902 for Larger Display Systems

S902 creates the multi-source canvas. When the final display system requires additional display-side processing, a downstream GeoBox processor can adapt that canvas to the physical display system.

LED WALL

Need Multi-Source Layouts on a Non-Standard LED Canvas?

Combine S902 + G901

Use S902 to build the multi-source presentation layout, then add G901 downstream when the LED system requires further cropping, scaling or custom output timing.

S902 manages source selection, window positioning, layering and profile recall, while G901 adapts the completed canvas to the LED controller and final LED wall format.

EDGE-BLENDED PROJECTION

Need Multi-Source Layouts on Edge-Blended Projectors?

Combine S902 + M810 / UD100

Use S902 upstream to create the multi-source presentation canvas, then use M810 or UD100 downstream to distribute that canvas across multiple projectors.

S902 remains responsible for the content layout, while the downstream processor handles projector-side cropping, geometry correction, edge blending and output synchronization.
