Dual 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. Datapath's VisionLC-HD2 provides a dual channel, high definition HDMI capture card for use within such environments.

Datapath's LiveStream: Capture architecture allows captured video to be processed in real time to a processor or graphics card. The VisionLC-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 VisionLC-HD2 natively supports 32, 24, 16 and 22 bit YUV ad RGB formats.

Multi-application capture
The VisionLC-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 VisionLC-HD2 is not supported for wall controller applications that depend on Datapath's MultiStream technology.

Video Streaming
Built upon the Microsoft AV stream model, VisionLC-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.

Tested applications includes:

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