Overview
SL NEO Digital Signage is a high-performance digital signage and video wall platform for synchronized delivery of video, graphics, information, and dynamic content across single displays, multi-screen installations, and large-format visual environments.
The platform supports up to eight independent 4K@60fps HDMI/DisplayPort outputs on a single server, with synchronized playback, configurable layouts, multi-layer compositions, real-time alpha blending, transitions, and free-form output transformations. Multiple screens can be controlled from a single playlist or operated independently.
SL NEO Digital Signage supports HAP, HAP Alpha/Q, H.264, HEVC, VP9, and AV1 media, together with dynamic text and real-time data from RSS feeds, files, databases, and external systems. Edge blending and geometric correction enable seamless projector and video-wall installations without requiring content to be pre-composed for every display configuration.
Designed for continuous 24/7 operation, the platform can be controlled locally or remotely through desktop and web interfaces and integrated with external applications through API-based workflows.
As part of the SL NEO Media Platform, Digital Signage integrates with media management, graphics, playlist control, and automation modules to support broadcast studios, corporate spaces, transportation hubs, retail environments, event venues, and other professional visual-display applications.

Workflow
In this mode, the Program module plays a single clip that internally contains images intended for output to multiple displays. The image is played back as a whole and then arbitrarily split before output.
A common use case is a setup where content for four HD screens is pre-composed into a single UHD file. During playback, this UHD image is split and processed as four independent HD signals.
The illustration shows an example of cutting two regions from one playing file and outputting them to two studio screens.
In this mode, all media files are prepared separately as multi-camera clips and are then played back synchronously by the Program module. The key advantage of this approach is that no pre-compositing into a higher-resolution format is required during preproduction.
The illustration shows an example of synchronized playback of two multi-camera clips and their output to two studio screens.
In this mode enables output image adjustments for seamless projector stitching. Supported capabilities include: Distortion compensation - geometric correction of the output image. It enables distortion compensation when a projector cannot be aligned with the
screen's center.
The image illustrates an ideal centered setup, a misaligned projector
When images from multiple projectors overlap, a zone of increased brightness appears. The Edge Blending option applies a smooth brightness gradient along the image edges, resulting in a seamless stitched picture with no visible joins.
Integrated Ecosystem
SL NEO Digital Signage is fully integrated into the SL NEO Media Platform — a modular, software-defined environment where media management, graphics, playlist control, automation, and output modules work together in real time.
Additional modules — including iMAM, Broadcast Graphics, Program Player, and the SL NEO Base Module — can be combined to build centralized digital signage, video wall, and multi-screen content-delivery workflows.
