Overview
SL NEO Compressed Video Playout, Recording & Local Insertions is a high-performance solution for ingesting, recording, and playing out pre-encoded video streams without unnecessary decoding or re-encoding. Designed for IP-centric broadcast, IPTV, and OTT workflows, it enables fast turnaround, precise control, and seamless SCTE-based local insertions.
The system supports live pass-through, file-based playout, and hybrid workflows, allowing broadcasters to mix live streams with pre-compressed content while maintaining minimal latency and maximum efficiency.
Built as part of the SL NEO Media Platform, the solution integrates seamlessly with graphics, delay, QC, and automation modules.

Workflow
End-to-end channel processing in compressed domain — enabling low latency, high efficiency, and cost-effective operation for telecom and broadcast workflows.
The system ingests compressed video streams from multiple sources:
▶ IP: UDP, RTP, SRT, RIST, Zixi
▶ OTT: HLS, MPEG-DASH
▶ DVB / ASI and file-based MPEG-TS
All signals are accepted without decoding or transcoding.
Processing is performed directly in the transport stream:
▶ SCTE-35 / SCTE-104 cue handling
▶ PID filtering and remapping
▶ PSI/SI processing
▶ PCR correction and timing alignment
Ensures low latency and full signal integrity.
Flexible playout control for linear channels:
▶ File and live stream playback
▶ Scheduled and event-driven switching
▶ SCTE-based automation
▶ Unified control via Air Manager
Precise content replacement in compressed streams:
▶ Local ad insertion and regionalization
▶ Blackout and content substitution
▶ Frame-accurate TS splicing
Simultaneous recording of streams:
▶ Native MPEG-TS recording
▶ Time-shift and catch-up TV
▶ Multi-channel recording
Delivery to broadcast and OTT environments:
▶ IP outputs: UDP, RTP, SRT, RIST, Zixi
▶ OTT: HLS, MPEG-DASH
▶ ASI output and CDN delivery
Integrated Ecosystem
The SL NEO Compressed Video Playout, Recording & Local Insertions 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 Program Player, Stream Capture, Transfer manager and other workflow components — can be integrated to create a fully tailored broadcast solution:
