Overview
SL NEO Digital Signage is a high-performance, multi-output system for managing, scheduling, and delivering stunning visual content across public displays, video walls, and commercial environments.
Built on the same robust engine powering broadcast operations, it handles high-bitrate 4K playback, complex layered compositions, and real-time content updates — all with the reliability you expect from a professional playout server.
From retail spaces to transportation hubs and corporate lobbies, SL NEO brings television-grade performance to digital signage.
As part of the SL NEO Media Platform, Digital Signage integrates seamlessly with graphics, ingest, playlist management, and automation modules — enabling a unified media workflow across one or many hardware platforms.
Optimized for 24/7 unattended operation, SL NEO Digital Signage ensures predictable, synchronized, and visually flawless playback on any scale.

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 specialized modules operate together in real time across one or more hardware platforms.
Additional modules — including Graphics, Program Player, and Base Module — can be combined to create a fully tailored solution:
