  • Single channel "LiveStream:Capture" card

    Discreet video capture is now the mainstay of many small form factor appliances being used in markets such as lecture capture, distance learning and medical environments. The EMS XtremeLC-HD2 provides a dual channel, high definition HDMI capture card for use within such environments. 

    EMS's LiveStream:Capture architecture allows captured video to be processed in real time to a processor or graphics card. The XtremeLC-HD2 supports on board colour space conversion and scaling, providing the ability to efficiently transfer the video signal making it suitable for rendering or encoding applications.

    The XtremeLC-HD2 natively supports 32, 24, 16 and 22 bit YUV ad RGB formats.

    Multi-application capture

    The XtremeLC-HD2 capture card has been designed for use within application models such as:

    • Medical environments
    • Simulation systems
    • Live events
    • PC and gaming console capture
    • Lecture and presentation capture
    • Real time streaming
    It is also possible to put more than a single card into a system for multiple capture channels.

    Due to the nature of the LiveStream:Capture architecture, the XtremeLC-HD2 is not supported for wall controller applications that depend on EMS's MultiStream technology.

    Video Streaming

    Built upon the Microsoft AV stream model, XtremeLC-HD2 inputs can be accessed and enumerated in any DirectShow or Media Foundation supported application. A video for Linux (V4L) driver package is also available to download.
