Overview
SL NEO Multiscreen is a software-based broadcast multiviewer and monitoring platform for centralized supervision of multiple video, audio, metadata, and signal sources across broadcast, production, master control, and IP environments.
The platform allows operators to build configurable mosaic layouts with multiple video windows, audio meters, clocks, logos, labels, alarms, and technical indicators on one or more displays. Layouts can be adapted for different operator roles, control rooms, channels, or monitoring tasks.
Multiscreen continuously monitors incoming signals and can visualize video and audio status, signal loss, freeze or black frames, audio levels, loudness, metadata, and other operational parameters. Configurable alarms and visual indicators help operators quickly identify problems and react before they affect transmission.
The platform supports SDI and IP-based workflows and can be used for master control rooms, production control rooms, network operations centers, contribution monitoring, and distributed broadcast facilities.
As part of the SL NEO Media Platform, Multiscreen integrates with ingest, playout, routing, redundancy, and monitoring workflows to provide centralized real-time supervision across broadcast infrastructure.

Workflow
Multiscreen analyzes video and audio signals in real time and generates alerts based on detected issues.
Usage: events, email notifications, automatic failover switching
Detection: Usage: events, email notifications, automatic failover switching
Detection:
Video Frozen, Video Black, Audio Silence, Audio Overload, No Signal
No Signal: instant detection without decoding, low CPU usage, works even for unavailable or remote streamsVideo Frozen, Video Black, Audio Silence, Audio Overload, No Signal
No Signal: instant detection without decoding, low CPU usage, works even for unavailable or remote streams
Multiscreen records all triggered alerts, providing a clear history of detected signal issues for monitoring and analysis.
Multiscreen allows saving configurations to files for backup and easy transfer between systems.
This tool enables users to create, edit, save, copy, and load all configurations — including PIPs and multiviewer layouts — both locally and remotely from any computer in the network.
Multiscreen can receive information from playlists in the Program Channel and Recorder modules and display it in the corresponding channel window (e.g., current clip, next clip).
It is possible to create separate PIPs with clocks, dates, and text using the built-in SL NEO Platform graphic designer.
Integrated Ecosystem
SL NEO Multiscreen is fully integrated into the SL NEO Media Platform — a modular, software-defined environment where signal monitoring, quality control, routing, redundancy, and transport-stream processing modules work together in real time.
Additional modules — including Easy Muxer, Media QC, Changeover, and SDI Router Controller — can be combined to build centralized monitoring, fault detection, and signal-control workflows across broadcast and IP infrastructures.
