Watch the IP25-R in Action
Learn how the IP25-R delivers low-latency, broadcast quality SMPTE ST 2110 IP-to-SDI/HDMI conversion. See real workflows, system integration examples, and more.

Rugged, Rack Ready Design with Flexible Configuration
The IP25-R is housed in a durable aluminum enclosure, ideal for both portable “throw-down” use and high-density rackmount installations. Up to three units can be mounted side-by-side in a single 1RU shelf—perfect for space-constrained environments. With AJA’s DRM2-Plus 3RU rackmount frame, redundant power can be provided for up to six IP25-Rs!

For fast setup, the front-facing USB-C port supports AJA’s free eMini-Setup application for easy initial network configuration. Multicast setup, internal routing, and output specific functions are accessed via the WebUI. Designed with active front-to-back cooling, the IP25-R ensures reliable, long-term performance in demanding broadcast and production locations.

Intuitive Web-Based Control
The IP25-R features a built-in web server that hosts a user-friendly, browser-based interface (WebUI) for easy configuration and control. Through the intuitive WebUI, users can quickly set up IP parameters, manage PTP synchronization, configure external control options, and monitor the video being fed to the outputs.

The interface also allows for flexible signal routing, enabling you to assign any of the six ST 2110 Rx inputs to specific SDI or HDMI outputs. You can also assign any of the 4 Tx inputs to specific 2110 streams. Additionally, users can fine-tune HDR metadata and colorimetry settings, as well as replicate output routing internally, making the IP25-R a powerful tool for IP-to-baseband monitoring and signal management.

New Tx Mode
The IP25-R now supports SDI to ST 2110 (Tx) signal conversion. You can convert up to 4x SDI signals into ST 2110 with support up to 12G-SDI, making this device the most flexible converter on the market. To ensure the signal integrity of the baseband to IP conversion, each ST 2110 and HDMI output has an optional Frame Sync with delay capability to ensure signals arrive when they are supposed to. When the ‘Timing’ slider is enabled, Frame Sync is activated and when the ‘Timing' button is selected, the Configure tab on the right will show the status and functions. ‘Input To Output Delay’ shows the input routed to the selected output pipeline. It also shows the input timing offset, relative to PTP. This is presented as H+V time, Frame Time, and Total Time (in ms).

Audio Tools
The IP25-R is not only a standout performer when it comes to video processing and configuration but also includes powerful audio capabilities to ensure maximum flexibility in production situations.

Audio Mapping:

New in v2.0 firmware is the ability to provide multi-audio stream mapping per video channel, supporting options between 1x16, 2x8, and 4x4 for interoperability with industry standard audio configurations. Also, ‘Audio Follows Video’ is now enabled by default for ease of use.

Audio Delay:

The IP25-R provides adjustment of audio timing in ms. When video is delayed, the same delay is applied to audio and presented as 0ms. 0ms delay is in relation to the video.

SMPTE ST 2110 Configuration and Diagnostic Tools
Beyond conversions, the IP25-R includes a robust set of tools for configuring and troubleshooting SMPTE ST 2110 networks. IP25-R helps you deploy, verify, and troubleshoot ST 2110 faster — often without needing a separate probe just to answer basic setup and maintenance questions.

Test Signal Generators
Each ST 2110 output can have an individual test signal enabled and set. This provides the capability to generate up to 4 individual ST 2110 test signals (bars, flat field, black, etc) with the option to enable a 1KHz tone as well. These signal generators are important tools for setting up and checking ST 2110 signal paths. The test pattern includes an optional on-screen overlay with the device hostname, time-of-day, and RJ45 control IP address, so the video output becomes a live “label” for the unit. If the WebUI isn’t reachable, and you need to start your network setup or troubleshooting, you can double-press the reset button to toggle the test pattern on, then double-press again to return to normal output.

ST 2110 Tools
Network Validation – Ping: • Ping a target IP directly from IP25-R per interface (control, media 1, media 2). Quickly confirm reachability when discovery and control aren’t behaving as expected — especially critical in multi-network facilities.
PCAP – Packet Capture File: • PCAP provides capability to capture stream (Ethernet/IP packets) data on all network interfaces at once for troubleshooting. Once captured, the file can be downloaded to your computer and opened with Wireshark.
SDP (Session Description Protocol) File Override: • Temporarily ignore specific SDP fields to prove whether media is present and isolate where the issue is — then restore standard behavior once resolved.
NMOS Flexible Discovery Modes: • Control how IP25-R searches for and connects to NMOS services across control vs media networks. Support for DNS-SD + mDNS and static registry IP options to align with your facility configuration.
Operational Statics: • Visibility into Rx/Tx bitrate, corrupt packets, and FEC errors, with counter resets for before/after validation.

HDR Support
High Dynamic Range (HDR) dramatically improves image quality by delivering richer colors, brighter highlights, and deeper blacks compared to standard dynamic range (SDR) signals. This results in more vibrant, true-to-life visuals, ensuring your audience experiences content as it was intended.

The IP25-R supports advanced HDR metadata handling, including SDI VPID and HDMI Infoframe signaling, making it ideal for modern HDR workflows. It simplifies the complexities of HDR integration by allowing HDR passthrough with metadata override to accurately map HDR metadata to all outputs.

This functionality ensures your IP-baseband conversion meets today’s HDR delivery requirements, whether for live production, broadcast, or postproduction environments.
