S902
S902 Flexible Multi-Source Layout Processor
Combine multiple UHD HDMI sources into controlled layouts for professional teaching, dvLED demo walls, simulation spaces and monitoring workflows.
S902 is designed for source layout processing before a large display, recording system, LED controller or GeoBox display processor.
Where S902 Fits in the Display Workflow
S902 sits before the display-processing layer.
It arranges multiple HDMI sources into a controlled layout before the signal is sent to a dvLED wall, projection system, display processor, recording device or monitoring display.

Application Workflows
When One Large Display Needs More Than One Source
S902 is most useful when several HDMI sources need to be arranged into repeatable layouts before the signal reaches the main display, recording system or downstream display processor.
It is designed for rooms where the same layout patterns are used repeatedly, and where a dedicated hardware processor is preferred over PC-based software composition.
Professional Teaching & Training Rooms
Workflow problem
Professional teaching and training rooms often need more than one source on the display. An instructor may need to show live camera, simulation output, reference material, software interface or remote input while recording the same teaching layout.
S902 role
S902 combines selected HDMI sources into repeatable teaching layouts and sends the result to the main display and recording, streaming or monitoring system.
dvLED Demo & Review Walls
Workflow problem
A dvLED wall is often large enough to show more than one source, but the system still needs a controlled way to arrange live sources. Software window management can make demonstrations, reviews and briefings less repeatable.
S902 role
S902 arranges multiple HDMI sources into fixed layouts before the signal is sent to the LED controller or downstream display processor.
Technical Monitoring & Control Stations
Workflow problem
Technical rooms, engineering stations or small production areas may need to compare or monitor several HDMI sources without installing multiple displays or a full broadcast multiviewer.
S902 role
S902 combines up to four HDMI sources into a monitoring layout and sends the result to an operator display and, when needed, to a secondary monitor or capture system.
S902 or G901?
Choose S902 when source layout flexibility is the main requirement.
Choose G901 when output format control is the main requirement.
| Requirement | Choose S902 | Choose G901 |
|---|---|---|
| Main need | Flexible source layout | Custom output format |
| Window layout | Free window editing | Preset / limited layout |
| Sources | Up to 4 HDMI sources | Fewer sources, stronger output control |
| Output | Dual HDMI output | Single programmable output |
| Custom resolution | No | Yes |
| Ultra-wide / special format | No | Yes |
| 90° / 270° rotation | No | Yes |
| 3D conversion | No | Yes |

What S902 Does Not Do
S902 is NOT designed for:
Output and display format
- no custom output resolution
- no 90° / 270° image rotation
- no 3D conversion
- no two fully independent output layouts
- Display processing
- no projector warping
- no edge blending
- no LED mapping
- no media-server playback
- System workflow
- no AV-over-IP routing
- no SDI broadcast multiviewing
- no tally, genlock, waveform or vectorscope functions
If your project requires these functions, the G900, M-series, UD-series or another system architecture may be more suitable.
Typical System Diagrams
S902 is placed before the downstream display-processing stage. It prepares the multi-source HDMI layout, while the following display system handles the physical display tasks such as LED mapping, projector alignment, edge blending, output distribution or custom resolution.
These diagrams show typical ways to use S902 as the source layout layer before a dvLED wall or projection system.

FAQ
Q1. Can S902 outputs show two completely different layouts?
No. S902 should not be treated as two fully independent layout processors. It is designed to send the processed layout to one or two HDMI destinations. If two fully independent layouts are required, the system architecture should be reviewed.
Q2. When should I choose S902 instead of G901?
Choose S902 when flexible multi-source window layout is the main requirement. Choose G901 when custom output resolution, ultra-wide output, rotation or 3D conversion is required.
Q3. Can S902 control an LED wall?
No. S902 does not replace an LED controller. It can be used before the LED controller to arrange multiple HDMI sources into a controlled layout.
Q4. Can S902 perform edge blending?
No. For projector warping and edge blending, use GeoBox M-series or UD-series processors.
Q5. Is S902 a broadcast multiviewer?
No. S902 is an HDMI multi-window processor. It does not provide SDI, tally, genlock, waveform, vectorscope or broadcast monitoring functions.
