4-Channel Video Capture and Overlay Controller for PC/104-Plus

The QuadGrabber is a 4-channel video capture and overlay controller on a single PC/104-Plus card providing a simple solution for capturing four concurrent analog video inputs for local system display or software analysis and processing. The QuadGrabber allows each of the 4 video channels to be captured at full D1 size, all at full frame rate and then scaled, cropped and positioned under software control. In addition to the video capture, the QuadGrabber also provides capture of up to 4 mono audio sources. The captured video data can be streamed continuously to system memory for immediate local display or further processing. The capture engine of the QuadGrabber features hardware color space conversion to present the captured video data in the format best suited to the end application.
