Digital Video Signal Processor for Video Walls, Scaling and Multi-Display Control
Inconsistent resolutions, incompatible signal formats, and fragmented source management routinely compromise multi-display installations in professional environments. A digital video signal processor resolves this by handling signal conversion, routing, scaling, and layout management within a single processing unit.
With our digital video signal processor, we deliver smooth video walls, multi-view layouts, 4K down-conversion, scaling, and reliable AV control for pro setups. The range spans video wall controllers, scalers, multiviewers, matrix switcher processors, and modular card-frame systems across compact 1RU to expandable 4RU form factors.
At Dutco Tennant LLC, we source digital video processing solutions from proven global manufacturers, supplying system integrators, consultants, contractors, and project developers across the UAE and GCC.
Precise Processing, Every Format, Every Layout
- A digital video processor accepts HDMI 2.0, DisplayPort, SDI, VGA, and IP stream inputs simultaneously, handling mixed signal formats from legacy and current-generation sources in one unit
- Bezel compensation calculates and corrects image alignment across tiled display arrays, compensating precisely for the physical border width of each panel
- FPGA-based processing delivers zero-latency seamless switching with no black screen or freeze frame across any source change
- Stored layout presets are recalled in a single command, allowing operators to switch content configurations during live events without disrupting active outputs
- Ultra-wide output resolution support covering 3840x600 and 5400x1920 feeds panoramic stretched-display installations without cropping or aspect ratio distortion
Core Technical Capabilities
- Signal Input Range: Accepts HDMI 2.0, HDBaseT, DisplayPort 1.2, SDI, DVI, VGA, and IP stream inputs with HDCP 2.2 compliance across all digital inputs
- Output Resolution: Per-output independent scaling from 640x480 up to 4K at 60Hz 4:4:4, supporting mixed-resolution display arrays from one central unit
- Multiview Layouts: Up to 16 configurable layout modes including PIP, PBP, quad split, and fully custom grid arrangements on a single output
- Audio Processing: De-embeds LPCM, Dolby TrueHD, and DTS-HD Master Audio to analogue or optical outputs with per-zone audio routing control
- Cascade Expansion: Units cascade to build video walls up to 6x6 (36 screens) without replacing core processing hardware as the installation grows
Types
Video Wall Controller
The video wall controller splits one or multiple video sources across a tiled screen array, delivering a unified large-format image with independent per-output scaling.
- Supports 2x2, 3x3, 4x1, 1x4, and custom m x n grid layouts with adjustable bezel correction applied per screen
- Image rotation at 90, 180, and 270 degrees accommodates portrait and landscape display orientations within the same wall array
- Dual redundant hot-swappable power supplies maintain continuous output in mission-critical installations where downtime is not acceptable
4K Scaler and Down-Converter
A 4K scaler and down-converter processes incoming 4K signals and outputs them at the correct resolution for any connected display, including legacy 1080p panels.
- Auto-scaling detects each display's native resolution via EDID and adjusts output automatically without manual configuration at each endpoint
- 4K to 1080p down-conversion allows 4K source content to feed existing HD displays without replacing installed hardware
- Up-conversion from 1080p to 4K maintains a consistent output resolution across arrays where panel generations are mixed
Multiviewer Processor
A multiviewer processor combines multiple independent video sources onto a single display, allowing operators to monitor all feeds simultaneously from one screen.
- On-screen labels, audio meter overlays, tally indicators, and timecode burn-in help broadcast and control room operators identify and assess each source feed
- Auto-switching triggers a full-screen cut to any source window based on user-defined input priority rules without manual intervention
- Supports PIP, PBP, quad-view, and up to 16-source grid layouts with fully customisable window sizes and positions across the output
Matrix Switcher Processor
A matrix switcher processor combines full matrix routing with video wall processing and multiview functionality in a single 3-in-1 unit.
- Routes any of up to 16 inputs independently to any of up to 16 outputs while enabling video wall and multiview modes on selected outputs simultaneously
- Web GUI, RS-232, TCP/IP, IR, and front panel control options allow the unit to integrate with any third-party room control or building automation system
- Write-protected firmware prevents unauthorised modification to system configuration, meeting the security requirements of government and critical infrastructure installations
Modular Card-Frame Processor
A modular card-frame processor uses an interchangeable card-slot chassis, allowing the system to be configured and expanded by slot rather than replaced as a whole unit.
- Supports up to 56 inputs and 56 outputs in a single 4RU chassis with field-replaceable input and output cards covering HDMI, SDI, DisplayPort, and IP formats
- Input and output cards are replaced during live operation without powering down the chassis, maintaining continuous signal output throughout
- Single chassis consolidates signal format conversion, routing, scaling, and wall processing, removing the need for separate conversion hardware at each input type
Standout Features & Benefits
Independent Window and Layer Control
- Any input is windowed, scaled, and positioned anywhere on the output canvas independently with full overlap and layering support across all active windows
- Graphic and text overlays including logos, scrolling tickers, and data burn-ins are applied on top of video windows without a separate overlay device
- Crop and zoom functions allow operators to select and magnify a specific region of any source input, displaying it full screen or within a defined window area
Broad Signal Format Compatibility
- Mixed input environments combining HDMI, SDI, VGA, IP streams, and analogue sources are managed within a single chassis without external format converters
- Universal input cards accept legacy analogue formats through DVI adaptors, extending the useful life of existing source equipment within a new processing infrastructure
- HDCP 2.2 compliance across all inputs and outputs ensures content-protected 4K sources play without handshake failures on any connected display
Mission-Critical Reliability
- Automated front panel LED and remote monitoring alerts notify operators of signal loss, fan failure, power supply status, and unauthorised module substitution immediately
- Maximum two-frame video latency is maintained regardless of the number of active sources, inputs, or simultaneous output modes running on the processor
- Proprietary frame synchronisation ensures pixel-accurate positioning across all active output windows with no tearing or frame drop during source transitions
Centralised Remote Management
- Full system configuration, layout management, source routing, and preset recall are accessible through a browser-based web GUI from any networked device
- REST API and SNMP support allow the AV video processing solution to integrate with enterprise monitoring platforms and custom automation workflows without proprietary software
- Multi-operator access lets different users manage separate zones or outputs concurrently from independent control terminals on the same processing unit
Application Area
Broadcast and Production Control Rooms
