IPMX


IPMX is a suite of open standards and specifications that provide an interoperable way to transport compressed and uncompressed video, audio, and related metadata over data networks within a multi-vendor IP audiovisual system. IPMX is based on the SMPTE 2110 and AES67 suite of standards, the related AMWA Networked Media Open Specifications and Video Services Forum's Technical Recommendations which add specific capabilities for Pro AV workflows.

Overview

IPMX is designed to transport and control media, including 4Kp60 video with 4:4:4 color, over standard Ethernet networks, with very low latency. IPMX, similar to other AV over IP standards and technologies, supports applications of high-performance media signals over packetized IP Networks instead of using traditional point-to-point cables such as HDMI, DisplayPort, and SDI. IPMX can be used in professional media environments such as broadcasting, live events, corporate communications, event space Pro AV, and educational facilities.
IPMX supports SD resolutions, Full HD, 4K Ultra HD and is ready for 8K resolutions and beyond. Additional capabilities beyond ST 2110 include HDMI InfoFrame packet transport, NMOS discovery and registration, I/O management, compressed media using the JPEG XS video coding system as well as new key exchange protocols for handing encrypted content between different products from different providers. IPMX can be used on a network with synchronous sources locked with Precision Time Protocol or with asynchronous sources.

History

In 2019 the Alliance for IP Media Solutions launched the IPMX roadmap. In 2022 and 2023, products from many manufacturers were showing IPMX working in live production and presentation workflows, and were also interoperating with synchronized SMPTE ST 2110 systems. In February 2024, the VSF's TR-10 was ratified.
