Overview
SL NEO Easy Muxer is a high-density transport stream processing solution designed for broadcast, IPTV, and IP delivery workflows. Supporting up to 64 inputs and 64 outputs, it enables flexible aggregation, remapping, and pass-through of MPTS and SPTS streams across DVB and ATSC environments, with an additional Time Shift capability for transport streams.
With native support for both IP and ASI interfaces — including UDP, RTP, SRT, RIST, and Zixi — the system seamlessly bridges legacy broadcast infrastructure and modern IP-based networks. Built-in monitoring, alarm handling, and redundancy mechanisms ensure reliable 24/7 operation in demanding broadcast environments.
SL NEO Easy Muxer integrates tightly into the SL NEO media platform, providing centralized control, automation, and scalability for headends, contribution networks, and playout systems.

Workflow
Easy Muxer goes beyond simple remultiplexing by enabling broadcast-safe pass-through from IP sources to ASI or satellite transmitters. Many IP transport streams are generated by standard servers, where timing and bitrate are driven by software clocks rather than precise hardware references. When such streams are fed directly into ASI or satellite equipment, timing instability can cause buffer overflows, underflows, and transmission errors.
Easy Muxer automatically stabilizes the stream in real time, regenerating PCR timing and managing stuffing packets to ensure a constant, transmitter-friendly bitrate. This allows IP-generated transport streams to be safely retransmitted over ASI or satellite links without modifications to the source encoder.
The result is a clean, compliant output that bridges IT-based encoding workflows with traditional broadcast transmission infrastructure — reliably and transparently.
Easy Muxer supports statistical multiplexing in conjunction with Playout modules, enabling the generation of MPTS streams with a fixed overall bitrate. This is essential in scenarios with strict output bitrate constraints, such as terrestrial multiplexes or satellite transponders. Available bitrate is dynamically allocated to the services that need it most, while maintaining a constant group bitrate and delivering the best overall picture quality.
Integrated Ecosystem
The SL NEO Easy Muxer 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 changeover, QC, and other workflow components — can be integrated to create a fully tailored broadcast solution:
