SMPTE ST 2110 is the broadcast industry standard that defines how uncompressed professional media is transported over IP networks as separate elementary streams. Unlike SDI, which multiplexes video, audio, and ancillary data together on a single coaxial cable, ST 2110 separates each essence into its own independent IP stream:

ST 2110-20  Uncompressed video  ·  ST 2110-30  Audio  ·  ST 2110-40  Ancillary data

Each stream can take a different route through the IP network and is synchronised at the destination using IEEE 1588 PTP timing. This separation gives broadcast facilities far greater flexibility in routing, monitoring, and processing individual signal components.

NMOS (Networked Media Open Specifications) is a set of open API standards from the Advanced Media Workflow Association (AMWA) that defines how IP-based media devices are discovered, registered, and connected in a broadcast network. It is the control layer that makes ST 2110 infrastructure manageable at scale.

Without NMOS, operators would need to manually configure IP endpoints and connections across every device on the network. With NMOS, devices register themselves automatically on startup and connections are managed through a common software interface. NMOS is mandated by the European Broadcasting Union (EBU) as part of their minimum requirements for building and managing an IP-based media facility.

NBOSS is Utah Scientific's software-based NMOS control solution, designed to streamline management of NMOS-compliant devices in hybrid SDI/IP environments. It solves the core operational challenge of hybrid workflows: managing SDI routing and ST 2110 IP flows from one control interface instead of two separate environments.

NBOSS sits between operator interfaces and the physical device layer, providing:

IS-04  Device discovery  ·  IS-05  Connection management  ·  IS-09  System parameters  ·  IEEE 1588 PTP  Timing awareness

All accessible from Utah Scientific's SC-4 hardware panels, Soft-LC panels, Web Panel, or any third-party NMOS controller. NBOSS is designed for use with Series 2 routers and On-Ramp devices.

IS-04 handles device discovery and registration — when a device comes online, IS-04 automatically registers it with the NMOS registry so the control system can see all available inputs, outputs, and devices on the network without manual configuration.

IS-05 handles connection management — once devices are registered, IS-05 defines how flows are routed and switched between them.

A simple way to think about it: IS-04 answers "what devices are available?" and IS-05 answers "how do I connect them?" Utah Scientific's NBOSS implements both, along with IS-09 for global system parameters, giving operators a complete NMOS control stack within a single Utah Scientific interface.

No. Utah Scientific's PassThrough cards and Gateway Router are PTP compliant with clocking not required — meaning the system can synchronise ST 2110 streams without a dedicated external PTP grandmaster clock device.

Additionally, the system supports simultaneous management of ST 2110 IEEE 1588 PTP timing alongside legacy analog Black Burst references for SDI infrastructure still in the signal chain. Facilities in the middle of an IP transition can run both timing domains without replacing existing timing infrastructure first.

Yes — this is one of the core operational advantages of Utah Scientific's approach. NBOSS enables operators to switch ST 2110 flows using the same SC-4 hardware panels, Soft-LC panels, and Web Panel interfaces already used for SDI routing. Operators do not need to learn a separate NMOS management interface or work in parallel control environments for different signal types — SDI crosspoints and ST 2110 IP flows are managed from the same familiar interface, on the same panel, in the same workflow.

Both products add SMPTE ST 2110 capability to Utah Scientific router installations, but they serve different infrastructure scenarios.

PassThrough card — slots directly into standard I/O positions inside an existing UTAH-400 Series 2 chassis, embedding ST 2110 encapsulation within the router frame without adding rack units. Supports ST 2022-6/8 and ST 2110, VLAN tagging, IGMP, and AMWA IS-04, IS-05, IS-06, with four 25Gb SFP+ ports per card.

On-Ramp — a standalone 1RU device that connects to any Utah Scientific router including UDS Compact and UHD-12G lines, with five hot-swappable card slots and 16 SFP cages. Also supports optional signal processing.

Use PassThrough cards for existing Series 2 installations. Use On-Ramp for UDS or UHD-12G installations, or when standalone gateway capability is needed.

SDI signals remain live automatically through the dedicated SDI path inside the chassis — no operator intervention required. The UTAH-400 Series 2 Gateway Router maintains a physical SDI connection for continuous signal flow that operates independently of the IP fabric.

If the NMOS controller crashes, the IP network loses connectivity, or NBOSS encounters any disruption, critical feeds continue routing via the SDI crosspoint matrix. This is a hardware-level failsafe — the SDI path is always live regardless of the state of the IP network or control software. This is the fundamental difference between Utah Scientific's embedded gateway architecture and the traditional approach of placing an external gateway between the SDI router and the IP network.

Yes. NMOS is an open specification standard, and Utah Scientific's NBOSS control solution is built on AMWA NMOS IS-04, IS-05, and IS-09 — the same open APIs used by all NMOS-compliant devices regardless of manufacturer.

This means NBOSS can discover and manage NMOS-compliant devices from other vendors on the same network, and third-party NMOS controllers can manage Utah Scientific devices. Broadcast facilities can build ST 2110 infrastructure using best-of-breed components from multiple manufacturers without being locked into a single vendor's proprietary control ecosystem.
