What Is the IPMX AV-over-IP Standard?

The IPMX AV-over-IP standard — short for Internet Protocol Media Experience — is an open set of specifications designed to move professional audio, video, and data across standard IP networks. It was created by the AIMS Alliance, the Video Services Forum (VSF), and AMWA to give the Pro AV industry a single, vendor-neutral platform.

Built on top of SMPTE ST 2110, the IPMX AV-over-IP standard adds features that broadcast-focused SMPTE ST 2110 does not cover on its own — including HDMI signal transport, HDCP content protection, and USB connectivity. This makes IPMX interoperability possible across a wide range of devices from different manufacturers.

Unlike proprietary AVoIP protocols that lock you into one vendor’s ecosystem, the IPMX open standard lets you mix and match certified equipment. Typical deployments include corporate meeting rooms, university campuses, live event production, LED video walls, and digital signage networks.

How the IPMX AV-over-IP Standard Works: TR-10 Specifications

The technical backbone of the IPMX AV-over-IP standard is a set of documents called the TR-10 specifications, published by the Video Services Forum (VSF). Each TR-10 document covers a specific part of the system. Together, they define how devices discover each other, transport media, and protect content — all over standard IP networks.

Here is what each IPMX specification covers:

• TR-10-0: General Organization — Introduces the overall IPMX framework and how the other specs relate to each other.
• TR-10-1: System Timing and Definitions — Defines clock synchronization and timing, including support for environments without PTP (Precision Time Protocol).
• TR-10-2: Uncompressed Active Video — Covers IPMX uncompressed video transport, aligned with SMPTE ST 2110-20.
• TR-10-3: PCM Digital Audio — Specifies audio transport over IP using uncompressed PCM audio, aligned with SMPTE ST 2110-30.
• TR-10-4: SMPTE ST 291-1 Ancillary Data — Handles ancillary data such as captions and timecode over IP.
• TR-10-5: HDCP Key Exchange Protocol — Enables HDCP content protection, a requirement for consumer and professional display ecosystems.
• TR-10-6: Forward Error Correction — Adds reliability to media streams across lossy or congested IP networks.
• TR-10-7: Compressed Video — Defines IPMX compressed video transport, supporting variable bit-rate codecs for bandwidth-efficient delivery.
• TR-10-8: NMOS Requirements — Specifies how devices use NMOS (Networked Media Open Specifications) for discovery, registration, and connection management via the control plane.
• TR-10-9: System Environments and Device Behavior — Sets baseline requirements for network infrastructure and device behavior in an IPMX deployment.
• TR-10-10: HDMI InfoFrame Packet Transport — Ensures HDMI metadata, such as HDR signaling and audio descriptions, travels correctly over IP.
• TR-10-11: Constant Bit-Rate Compressed Video — Covers CBR compressed video for applications where predictable bandwidth is critical, such as live production.
• TR-10-12: AES3 Transparent Transport — Allows legacy AES3 digital audio signals to travel transparently across an IPMX network.
• TR-10-13: Privacy Encryption Protocol (PEP) — Provides end-to-end encryption for media streams to protect sensitive content.
• TR-10-14: IPMX USB — Extends the IPMX AV-over-IP standard to include USB peripheral transport, enabling keyboard, mouse, and other USB device sharing over IP.

IPMX vs. Proprietary AV-over-IP Protocols

One of the biggest advantages of the IPMX AV-over-IP standard is that it replaces closed, vendor-specific systems with a single open framework. Proprietary AVoIP protocols — such as SDVoE, HDBaseT, and NDI — each work well within their own ecosystems but cannot interoperate with each other without gateways or converters.

With the IPMX open standard, a display from one manufacturer can receive a signal from an encoder made by a completely different company — as long as both are IPMX-certified. This is the same promise that SMPTE ST 2110 delivered for broadcast, now extended to Pro AV environments.

The IPMX AIMS Alliance — the Alliance for IP Media Solutions — actively promotes the IPMX standard and works with manufacturers including Matrox Video, Barco, Nextera Video, and PlexusAV to develop IPMX-ready products. As of 2026, the number of certified devices is growing rapidly, and interoperability demonstrations are regularly held at events like the NAB Show and IBC.

Key Benefits of the IPMX AV-over-IP Standard for Pro AV Deployments

Choosing the IPMX AV-over-IP standard for your next project delivers several practical advantages:

• Vendor flexibility: Mix certified products from multiple manufacturers without compatibility concerns.
• Scalability: IP-based AV distribution scales from a single meeting room to a campus-wide or multi-site network using standard IT infrastructure.
• Unified media transport: A single IPMX network carries uncompressed video, IPMX compressed video, audio transport over IP, data, and control signals simultaneously.
• Built-in security: HDCP and the Privacy Encryption Protocol (PEP) protect content at the network level.
• Simplified management: NMOS integration gives IT and AV teams a standardized way to discover and manage all devices on the network through the control plane.
• Future-proof investment: Because IPMX is an open standard, it evolves through industry consensus rather than a single vendor’s roadmap.

Frequently Asked Questions About the IPMX AV-over-IP Standard

What does IPMX stand for?

IPMX stands for Internet Protocol Media Experience. The IPMX AV-over-IP standard is an open collection of specifications that defines how professional audio, video, and data are transported over standard IP networks in Pro AV environments.

Is IPMX an open standard?

Yes. The IPMX open standard is developed and maintained collaboratively by the AIMS Alliance, the Video Services Forum (VSF), and AMWA. Any manufacturer can build IPMX-compliant products without paying licensing fees to a single company, which is the core difference between IPMX and proprietary AVoIP protocols.

What is the difference between IPMX and SMPTE ST 2110?

SMPTE ST 2110 was designed for broadcast and live production environments. The IPMX AV-over-IP standard extends SMPTE ST 2110 with Pro AV-specific features including HDMI signal transport, HDCP content protection, USB connectivity, and support for networks that do not use PTP clock synchronization. Think of IPMX as SMPTE ST 2110 plus the extra capabilities the Pro AV world needs.

What is the IPMX TR-10 specification?

IPMX TR-10 is the family of technical documents that define every aspect of the IPMX AV-over-IP standard — from system timing and uncompressed video to compressed video transport, HDCP, NMOS, USB, and encryption. Each TR-10 document covers one specific area so manufacturers can implement only the parts relevant to their product.

Which organizations support the IPMX standard?

The IPMX AIMS Alliance (Alliance for IP Media Solutions) is the primary industry body promoting the standard. The Video Services Forum publishes the TR-10 specifications, and AMWA develops the NMOS APIs used for device discovery and control. Equipment manufacturers including Matrox Video, Barco, Nextera Video, and PlexusAV have all announced or shipped IPMX-ready products.

What are the real-world use cases for the IPMX AV-over-IP standard?

The IPMX AV-over-IP standard is well-suited for IPMX live production environments, corporate AV installations, university campuses, digital signage networks, houses of worship, and broadcast facilities that also handle Pro AV signals. Because IPMX supports both compressed and uncompressed media over standard IP infrastructure, it fits a wide range of bandwidth and latency requirements.
