MUNICH– ARRI has unveiled SMPTE ST 2110 support for the ALEXA 35 Live multicam system, opening the system to fully IP-based broadcast studios, stadiums, high-end flypacks, and remote productions and will exhibit the development as well as its other enhancements for live entertainment workflows during IBC2026, Sept. 11-14, at the RAI Amsterdam Convention Center.
Delivered through Software Update Package (SUP) 1.5.0 for the Live Production System LPS-1, the new support brings ALEXA 35 Live directly into modern ST 2110 infrastructures through a permanent software license.
By combining ARRI’s cinematic image quality with open IP standards and proven live-production reliability, the update strengthens ALEXA 35 Live as a platform for the next generation of high-end media and entertainment workflows.
The ST 2110 implementation enables independent routing and control of uncompressed video, multichannel audio, and time-sensitive metadata over a 25GbE full-duplex connection. It can simultaneously transport two uncompressed UHD camera feeds alongside multiple HD or UHD return-video and return-AUX channels. Multiple HD streams also support HFR slow-motion acquisition over IP.
For resilient live production, the implementation includes seamless SMPTE ST 2022-7 redundancy. With two third-party SFP28 25GbE fiber-optic transceiver modules installed at the rear of the LPS-1, the unit maintains dual active network paths for automatic, glitch-free failover. Recommended transceiver modules are listed in the LPS-1 SUP 1.5.0 user manual.
Proven in demanding live-production environments
The LPS-1 ST 2110 architecture is designed for interoperability with broadcast ecosystems, including Riedel Communications infrastructure and SimplyLive production environments. Comprehensive AMWA NMOS support (IS-04, IS-05, IS-08, IS-09, BCP-003-01 and BCP-003-03) and Precision Time Protocol (PTP) enable automated discovery, connection management, audio-channel mapping, synchronization and secure operation across the media network.
Supported standards and protocols include:
- 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)
- AMWA NMOS Suite: IS-04 discovery and registration, IS-05 connection management, IS-08 audio channel mapping, IS-09 system parameters, BCP-003-01 secure communication and BCP-003-03 authorization.
LPS-1 SUP 1.5.0 can be downloaded from the ARRI website. The LPS-1 ST 2110 license is available from the ARRI License Shop. It is priced at $8,735 (U.S.) or €7,500.
