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-SDI4 provides four 3G SDI 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-SDI4 is capable of capturing video at full quality whilst mixing in overlay data into the live monitoring path without adding latency other than a few pixels.
The XtremeRT-SDI4 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-SDI4 offers a uniquely unparalleled and professional solution to the market.
INSTANT CAPTURE AND DISPLAY
Many video applications demand the highest level of accuracy. Video needs to not only be captured for storage or processing, but also needs to be seen in real time by professionals in cutting edge events. EMS’s XtremeRT range of capture cards offer the ability to capture high quality video and loop inputs directly to outputs, creating latency at just a few pixels. Signals are delivered to the primary display, even if the host PC stops functioning.
ZERO LATENCY OVERLAY
The XtremeRT series also offers an on-board alpha blending capability, allowing a secondary source of frames to be overlaid on to the outgoing display in real time. The optional use of an overlay watchdog ensures that the application supplying the overlay is in constant control. If any problems are detected the card will ensure integrity of the primary signal by preventing the overlay from obscuring the live signal.
MISSION CRITICAL 24/7 OPERATION
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.
XtremeRT PERFORMANCE FEATURES
The XtremeRT 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:
• 4 x 3G SDI inputs
• Telestream WireCast
• Opencast Matterhorn
• OBS Project
• Adobe Flash Media Encoder
• Dataton Watchout
Any application compatible with Windows® DirectShow technology can use the XtremeRT 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®.
