Zero Latency Loop Through with Overlay
The EMS XtremeRT-XD2 provides two 4K capable zero latency loop through ports, each with alpha-blended overlay capability.


Today’s most popular 4K video standards are inherently point-to-point in nature, yet systems are required to split video pipelines whenever capture and monitoring is required simultaneously. Duplicating frames in software adds latency and uses system resource, whilst external signal splitters are often too cumbersome and unreliable for many professional applications.

The EMS XtremeRT-XD2 provides two 4K capable zero latency loop through ports, each with alpha-blended overlay capability. When connected in series between the video source and the local monitor, the XtremeRT-XD2 is capable of capturing video at full quality whilst mixing in overlay data into the live monitoring path without adding latency.

The XtremeRT-XD2 offers a unique solution for the operator who needs both live video and overlay data to be displayed on a single monitor, whilst recording the stream in the background. Whether in a Medical Operating Room overlaying patient data onto surgical camera inputs, or whether adding overlays in Augmented Reality (AR) based applications, the XtremeRT-XD2 offers a uniquely unparalleled and professional solution to the market.


The XtremeRT-XD2 provides a fail-safe mechanism for the loop through ports, requiring only power for video pass through to be operational. Additionally, the overlay hardware contains a timeout mechanism to prevent applications from corrupting the main video feed in the event of a software crash or other system failure.


The VisionIO series is supported by the EMS XtremeRT Performance Driver. Optimised at the lowest level to work efficiently with proprietary EMS hardware, the XtremeRT Performance Driver provides users with a variety of features including Livestream, Multi-Stream, Precision Hardware Timestamping, Efficient DMA Transfer, Flexible Signal Detection and Automatic Mode Changing.


DirectShow drivers for WDM Streaming supports the following applications, to encode, record and stream video over networks or the Internet:

• Microsoft Media Encoder
• Telestream WireCast
• vMix
• Opencast Matterhorn
• VidBlaster
• OBS Project
• Adobe Flash Media Encoder
• Dataton Watchout

Any application compatible with Windows® DirectShow technology can use the VisionIO due to the built-in WDM support. The latest Windows Media Foundation Framework is also supported under the AVStream minidriver framework, allowing application development suitable for the Windows 10 App Store®.
