ARRI Adds SMPTE ST 2110 IP Support to ALEXA 35 Live

On September 9, 2026, ARRI announced the release of SMPTE ST 2110 support for the ALEXA 35 Live – Multicam System via Software Update Package (SUP) 1.5.0 for the Live Production System LPS-1. Available through a permanent software license, the update integrates cinematic camera workflows directly into IP-based broadcast studios, stadiums, and remote productions.

Engineering the IP Transition for Broadcast Infrastructure

By adding SMPTE ST 2110 natively to the LPS-1 base station, the system bridges high-end digital cinematography with the demanding real-time requirements of modern IP facilities.

Furthermore, multiple HD streams support HFR slow-motion acquisition over IP, ensuring that high-frame-rate replay directors don’t lose their preferred capture formats when cutting over to a packet-switched network layer.

Redundancy and Reliability in Live Touring Environments

To prevent dropped frames and dropped audio packets during mission-critical events, ARRI built seamless SMPTE ST 2022-7 redundancy directly into the LPS-1 architecture. By installing two third-party SFP28 25GbE fiber-optic transceiver modules at the rear of the base station, operators establish dual active network paths. If the primary line suffers disruption, the system executes an automatic, glitch-free failover.

Adlib, a UK-based live production and systems integration specialist, put this exact failover mechanism through its paces during field testing. Ashley Ball, Video Technical Manager at Adlib, evaluated a pre-release version of the LPS-1 ST 2110 License within a high-end video production platform built for a major arena tour.

Open Standards and Interoperability Across Ecosystems

ARRI designed the LPS-1 ST 2110 architecture to integrate cleanly with established broadcast ecosystems, including Riedel Communications infrastructure and SimplyLive production environments.

To achieve this level of plug-and-play harmony, the software relies on an extensive suite of AMWA NMOS protocols alongside Precision Time Protocol (PTP). The implementation officially supports:

• SMPTE ST 2110-10: System timing and synchronization (PTP)
• SMPTE ST 2110-20: Uncompressed active video transport
• SMPTE ST 2110-21: Traffic shaping and packet timing
• SMPTE ST 2110-30: PCM audio transport (AES67 compatible)
• SMPTE ST 2110-40: Ancillary data transport (captions, VITC, timecode)
• SMPTE ST 2022-7: Seamless protection switching (hitless redundancy)

This guarantees automated discovery and secure operation across complex enterprise media networks.

Deployment and Availability

LPS-1 SUP 1.5.0 is available for download directly from the ARRI website. Facilities and systems integrators looking to light up the new functionality can acquire the permanent LPS-1 ST 2110 License via the ARRI License Shop. With the update rolling out globally, ARRI is showcasing live entertainment workflows and the updated hardware stack at IBC, giving broadcast engineers an up-close look at how uncompressed cinematic sensors fit into the world of IP packet routing.
