Single channel "LiveStream Capture" card
Discreet video capture is now the mainstay of many small form factor appliances being uses in markets such as lecture capture, distance learning and medical environments. Datapath's VisionLC-HD provides HDMI capture for use within such applications.

Datapath's LiveStream Capture architecture allows captured video to be processed and delivered in real time to a processor or graphics card. The VisionLC-HD 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 VisionLC-HD natively supports 32, 24, 16 and 12 bit YUV and RGB formats.

Multi-application capture
The VisionLC-HD 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 VisionLC-HD is not supported for wall controller applications that depend on Datapath's MultiStream technology.

Video streaming
Built upon the Microsoft AV stream model, VisionLC-HD 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
  • OBS Project
  • Adobe Flash Media Encoder
  • Dataton Watchout
