IPMX

Last updated

IPMX (Internet Protocol Media Experience) is a suite of open standards and specifications that provide an interoperable way to transport compressed and uncompressed video, audio, [1] and related metadata over data networks within a multi-vendor IP audiovisual system. [2] IPMX is based on the SMPTE 2110 [3] [ circular reference ] [4] and AES67 suite of standards, the related AMWA Networked Media Open Specifications (NMOS) and Video Services Forum's (VSF) Technical Recommendations (TR-10) which add specific capabilities for Pro AV (professional audio visual) workflows. [5] [6] [7] [8]

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. [9] IPMX, similar to other AV over IP (Audio Visual over Internet Protocol) 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. [10] [11] IPMX can be used in professional media environments such as broadcasting, live events, corporate communications, event space Pro AV, and educational facilities. [12]

IPMX supports SD (standard definition) resolutions, Full HD, 4K Ultra HD and is ready for 8K [13] resolutions and beyond. [14] Additional capabilities beyond ST 2110 include HDMI InfoFrame packet transport, NMOS discovery and registration, [15] I/O management, compressed media using the JPEG XS video coding system [16] as well as new key exchange protocols for handing encrypted content between different products from different providers. [17] [18] IPMX can be used on a network with synchronous sources locked with Precision Time Protocol (PTP) or with asynchronous sources. [19] [20]

History

In 2019 the Alliance for IP Media Solutions (AIMS) launched the IPMX roadmap. [21] [22] 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. [23] [24] In February 2024, the VSF's TR-10 was ratified. [25] [26] [27]

TR-10 Specifications [28]
