The New AV over IP Open Standard for Pro AV

Brompton is working closely with AV-over-IP experts Nextera Video and Adeas, as well as Altera, the FPGA brand from Intel, to deliver products supporting AV-over-IP standards such as ST2110 and IPMX. We asked Jed Deame, CEO of Nextera Video, to tell us about IPMX, the new AV over IP Open standard for Pro AV.

Question: What is IPMX? 

IPMX (Internet Protocol Media Experience) is the only set of true open standards and specifications to enable the carriage of compressed and uncompressed video, audio, and data over IP networks for the Pro AV market. 

An essential goal of IPMX is to deliver the same type of pluggable video experience that users expect with HDMI or DisplayPort. It includes provisions for control (NMOS), copy protection (HDCP), connection management (EDID), and security. In addition, IPMX provides for USB virtualization and extension to enable interoperable KVM deployments. 

IPMX was created by AIMS (the Alliance for IP Media Solutions), a non-profit trade alliance that fosters the adoption of one set of common, ubiquitous, standards-based protocols for interoperability over IP in the media and entertainment (M&E) and professional audio/video industries. IPMX builds on foundational work from SMPTE, AWMA, and VSF. 

Question: What does IPMX consist of? 

Media Transport – IPMX builds upon the industry-proven SMPTE ST 2110 standard. ST 2110 is the de facto IP protocol adopted by the M&E industry for carriage of video, audio, and data over IP networks. Its support for both uncompressed and compressed video and audio makes it a strong foundation for Pro AV applications as well.  

Control and Security – IPMX leverages AMWA’s NMOS suite of specifications to provide the “plug and play” capabilities needed to easily add and integrate devices in an IP media workflow. When a device is powered up, its resources become available to all devices on the network, removing the need for time consuming manual configuration of I/O parameters. 

Compression – Currently, IPMX supports uncompressed but more commonly uses the JPEG-XS codec to provide visually lossless quality with low implementation complexity, low power, and extremely low latency (a few lines of video).  Support for other codecs such as NDI and H.264 are in the works. 

Timing – While IPMX supports ST 2059 PTP, enabling compatibility with broadcast systems, one of its biggest benefits is providing synchronous communication without PTP or any other sync reference. 

Key Features 

  • Standards based for guaranteed interoperability 
  • Visually lossless 4Kp60 over 1G networks 
  • Any resolution from SD to 8K and beyond 
  • All color modes, pixel formats, and frame rates 
  • Near zero latency 
  • Synchronous and asynchronous clocking 
  • Any network (1G, 2.5G, 5G, 10G, 25G+) 
  • Supports USB, HDCP, and Control Security 

Question: Why is IPMX Important? 

IPMX takes an open standards approach to ensure that accessibility, ease of use, and implementation are available to all. The developers of this specification come from organizations that represent the best interests of the Pro AV market as a whole, rather than the interests of just a few. This is in contrast to other solutions that, while calling themselves standards, are owned by a single entity who controls their intellectual property, and their underlying technologies are often ad hoc and not peer reviewed. 

Because IPMX comes from SMPTE, AMWA, VSF and AIMS, it is truly open and interoperable. Manufacturers will win by reducing the number of ad hoc IP formats they need to develop and support.  Integrators win by having the freedom to choose the best solutions to fit any installation and network with automatic device discovery, saving time and frustration on the job. End users will enjoy multi-vendor interoperable products with proven technologies and optimal performance. 

Brompton endorses open standards and is currently developing IPMX products. Brompton is proud to partner with Nextera for IPMX. 

Nextera Video offers IPMX and ST 2110 FPGA IP cores and NMOS control software to help OEMs IPMX-Enable their products quickly and easily. For more information on the Nextera IPMX solution, email sales@nexteravideo.com 

Brompton Technology is proud to be using the latest technology from Altera and grateful for their close support.
