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

This VisionLC-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 VisionLC-SDI natively supports 32, 24, 16 and 12 bit YUV and RGB formats.


Multi-application capture

The VisionLC-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 VisionLC-SDI s not supported for wall controller applications that depend on Datapath's MultiStream technology.

Video streaming

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