Discrete 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 captured 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:

• 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-SDI is 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 include:

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