VisionLC-HD2 Capture Card

Description

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:

• Real time streaming

It is also possible to put more than a single card into a system for multiple capture channels.
