Overview
SL NEO Time Delay provides reliable control over live broadcasts, enabling operators to delay, review, and manage content before it goes to air. The system supports flexible delay configurations from minutes up to 24 hours, ensuring protection against unwanted content and enabling time-shifted workflows.
Designed for multi-channel operations and compliance with local regulations, the platform offers an intuitive NLE-style timeline of the delayed signal. Operators can review content in advance, mark unwanted segments with In/Out points, and apply real-time processing such as blur, blackout, freeze, or overlays to both video and audio.
AI-assisted content detection allows automatic monitoring of multiple channels based on predefined rules, highlighting suspicious segments for operator validation. Final decisions always remain under full operator control.
The system also supports seamless replacement of advertising or other content blocks with localized inserts. With support for SD to UHD across SDI and IP streams, SL NEO Time Delay fits seamlessly into modern broadcast workflows.

Integrated Ecosystem
The SL NEO Time Delay is fully integrated into the SL NEO media services platform — a modular, software-defined environment where specialized modules operate together in real time across one or more hardware platforms.
Additional modules — including graphics, ad-insertion, and other workflow components — can be integrated to create a fully tailored broadcast solution:
SL NEO TS Multiplexer
For stream preparation and validation.
SL NEO Playout
For localization, commercial block insertion, and channel branding.
SL NEO Device Control
Automates source switching and responses to signal faults.
Control Systems Integration
Communicates via SCTE-104/35, GPIO, and REST API for AIdriven workflows and third-party automation systems.
Use Cases
Regional Insertion and Compliance
Use buffer segments for content switching, regional ad or program replacement, graphics overlays, or age gating based on jurisdiction or time zone.
Events Broadcast
Manage sensitive advertisement embedded in the content such as gambling ads by blurring the overlays.
Turnaround Channel & OTT Preparation
Validate TS and SDI content, replace or remove ads and inappropriate material, and insert binge markers to generate clean VOD exports.
