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] [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.

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]

The TR-10 specifications for Pro AV workflows are the following:

The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP is used in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications including WebRTC, television services and web-based push-to-talk features.

The Session Announcement Protocol (SAP) is an experimental protocol for advertising multicast session information. SAP typically uses Session Description Protocol (SDP) as the format for Real-time Transport Protocol (RTP) session descriptions. Announcement data is sent using IP multicast and the User Datagram Protocol (UDP).

Material Exchange Format (MXF) is a container format for professional digital video and audio media defined by a set of SMPTE standards. A typical example of its use is for delivering advertisements to TV stations and tapeless archiving of broadcast TV programs. It is also used as part of the Digital Cinema Package for delivering movies to commercial theaters.

Professional video over IP systems use some existing standard video codec to reduce the program material to a bitstream, and then use an Internet Protocol (IP) network to carry that bitstream encapsulated in a stream of IP packets. This is typically accomplished using some variant of the RTP protocol.

The Technology and Engineering Emmy Awards, or Technology and Engineering Emmys, are one of two sets of Emmy Awards that are presented for outstanding achievement in engineering development in the television industry. The Technology and Engineering Emmy Awards are presented by the National Academy of Television Arts and Sciences (NATAS), while the separate Primetime Engineering Emmy Awards are given by its sister organization the Academy of Television Arts & Sciences (ATAS).

In audio and broadcast engineering, audio over Ethernet (AoE) is the use of an Ethernet-based network to distribute real-time digital audio. AoE replaces bulky snake cables or audio-specific installed low-voltage wiring with standard network structured cabling in a facility. AoE provides a reliable backbone for any audio application, such as for large-scale sound reinforcement in stadiums, airports and convention centers, multiple studios or stages.

Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices, and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI. Standards also exist for the carriage of uncompressed video over computer networks.

HDBaseT is a consumer electronic (CE) and commercial connectivity standard for transmission of uncompressed ultra-high-definition video, digital audio, DC power, Ethernet, USB 2.0, and other control communication over a single category cable up to 100 m (328 ft) in length, terminated using 8P8C modular connectors. The conductors, cable, and connectors are as used in Ethernet networks, but are not otherwise exchangeable. HDBaseT technology is promoted and advanced by the HDBaseT Alliance.

SMPTE ST 2071 is a suite of standards published by the Society of Motion Picture and Television Engineers (SMPTE) that define a framework, protocol, and method of service discovery for the control of objects within an Internet of Things. The standards focus on the interoperability and discoverability of objects within the network, and treat media as first-class citizen. The standard also describes a programming methodology that allows objects to describe their behaviors (features) to other objects over the network and allows objects to change their behavior dynamically at runtime. Application developers developing to the SMPTE ST 2071 standards focus on writing their applications to the behaviors they wish to support and not the object or class of object that implements those behaviors.
