IPMX Activity Group Marks Major Interoperability Milestone Ahead of 2025 NAB Show

The Alliance for IP Media Solutions (AIMS) and the Video Services Forum (VSF) have successfully completed the IPMX Tested Event 2025, marking a key step in making IPMX (Internet Protocol Media Experience) ready for real-world AV-over-IP applications. Held at Evertz in California, this event brought together 12 top companies to test their IPMX gear for video, audio, and system interoperability. The results showed strong compatibility and highlighted IPMX’s potential as a scalable and open AV-over-IP solution built on familiar standards like SMPTE ST 2110 and AMWA NMOS — but with tweaks to better fit Pro AV needs.

This successful test not only confirms IPMX’s readiness but also helps refine the test process and technical specs for broader industry adoption. With more companies earning IPMX Early Adopter badges, IPMX will be a big focus at the 2025 NAB Show in Las Vegas, where visitors can see live demos, attend training sessions, and learn how this open standard is shaping the future of AV systems over IP networks.

The Alliance for IP Media Solutions (AIMS) and the Video Services Forum (VSF) today announced the successful completion of the IPMX Tested Event 2025, a significant milestone in the development and validation of the Internet Protocol Media Experience (IPMX) set of specifications.

Held at Evertz in Burbank, California, from March 24 to 28, this multivendor interoperability event brought together 12 leading companies to put IPMX devices and systems through a comprehensive series of tests based on the IPMX Tested Test Plan and key IPMX technical documents. The event confirmed successful interoperability across all tested profiles for video, audio, and system behavior — laying critical groundwork as the IPMX project advances toward its next phase.

IPMX is an open, interoperable set of specifications designed to bring Pro AV systems into the world of IP-based media transport. Built on the proven foundations of SMPTE ST 2110 for media transport and the AMWA NMOS suite for discovery, registration, and control, IPMX adds essential features tailored for Pro AV workflows, including support for compressed video, simplified system timing, HDCP, and system profiles to make deployment more practical and scalable.

Importantly, IPMX is not a departure from ST 2110 and NMOS — it is an adaptation, designed for compatibility while reducing the complexity often associated with broadcast-centric deployments. The goal is to make ST 2110 and NMOS technologies more accessible and interoperable for manufacturers and integrators serving the larger Pro AV market.

Strong Results Signal Readiness
“The results of this year’s testing event are a testament to the dedication and collaboration of the companies participating in IPMX,” said Jack Douglass, chair of the IPMX Activity Group. “We are progressing rapidly and steadily toward delivering IPMX to the industry, and these successful results show that IPMX will provide the interoperable, scalable, and open AV-over-IP solution that the professional AV market needs.”

Building on the momentum from prior testing events, the IPMX Tested Event 2025 not only validated the strength of the specifications but also provided valuable insights for refining the IPMX Tested Test Plan. Enhancements to NMOS testing, clearer infrastructure guidelines, and expanded automation are all being prioritized to ensure a smooth and trusted certification process.

Participating companies earned IPMX Early Adopter and IPMX Supporter badges, which will be proudly displayed on their products and at their 2025 NAB Show booths, highlighting their leadership and commitment to advancing open standards.
