  • 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 XtremeLC-SDI provides tri-band SDI capture for use within such applications. Our LiveStream:Capture architecture allows captures video to be processed and delivered in real time to a processor or graphics card.

    This XtremeLC-SDI supports on board colour space conversion and scaling, providing the ability to efficiently transfer the video signal in a suitable format for rendering or encoding applications. The XtremeLC-SDI natively supports 32, 24, 16 and 12 bit YUV and RGB formats

    Multi-application capture

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

    A few example applications:

    • Medical environments
    • Simulation systems
    • Live events
    • PC and gaming console capture
    • Lecture and presentation capture
    • RealTime 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-SDI s not supported for wall controller applications that depend on EMS's MultiStream technology.

    Video Streaming

    Built upon the Microsoft AV stream model, XtremeLC-SDI 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.

    Tested applications includes:

    • Microsoft Media Encoder
    • VLC
    • Telestream WireCast
    • vMix
    • Opencast Matterhorn
    • VidBlaster
