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] 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.[4][5][6][7]
Overview
[edit]IPMX is designed to transport and control media, including 4Kp60 video with 4:4:4 color, over standard Ethernet networks, with very low latency.[8] 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.[9][10] IPMX can be used in professional media environments such as broadcasting, live events, corporate communications, event space Pro AV, and educational facilities.[11]
IPMX supports SD (standard definition) resolutions, Full HD, 4K Ultra HD and is ready for 8K[12] resolutions and beyond.[13] Additional capabilities beyond ST 2110 include HDMI InfoFrame packet transport, NMOS discovery and registration,[14] I/O management, compressed media using the JPEG XS video coding system[15] as well as new key exchange protocols for handing encrypted content between different products from different providers.[16][17] IPMX can be used on a network with synchronous sources locked with Precision Time Protocol (PTP) or with asynchronous sources.[18][19]
History
[edit]In 2019 the Alliance for IP Media Solutions (AIMS) launched the IPMX roadmap.[20][21] 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.[22][23] In February 2024, the VSF's TR-10 was ratified.[24][25][26]
