Video digitizer for live video and image capture

Video Capture

Video from any analogue source (composite or S-Video) can be captured as either still frame video images or motion video. Composite video inputs are provided as female RCA jacks, while S-Video uses a standard 4-pin DIN connector. The ImpactVCB comes with a VFW (Video for Windows) capture drivers for Windows 95 and Windows NT, and a WDM driver for use with Windows XP, Windows 98SE, Windows Me and Windows 2000. Typical capture rates range from 15 to 30 fps depending on system configuration.

Live Video Display

The ImpactVCB can display live video from NTSC or PAL video sources in a resizable window on the PC screen. The digitizing of the analogue video signal is performed by hardware on the ImpactVCB, there by not slowing down the CPU. After video is digitized it is drawn by the ImpactVCB directly into the memory of the PC's Graphics card. This uses a feature of Windows called Direct Draw, and the ImpactVCB can be used with most Graphics cards which support Direct Draw 5 or higher. This technique is used on Windows 95, Windows 98, Windows ME, Windows 2000 and WindowsNT 4.0

Video capture board with live overlay

ImpactVCB is part of a low cost family of video capture boards which can be used as the heart of a live video display, real time video capture, streaming video or video conferencing solution.

The ImpactVCB board provides image capture from a desk top CCD camera or other analogue input. Impact VCB board is a small 1/3 height PCI board based on the Conexant 878A video digitizer chipand requires a single PCI slot. A graphics card with Direct Draw 3 (or later) capability is required for Live Display. Operating system can be Window 95, Windows 98, Windows ME, NT 4.0, Windows 2000 and Windows XP. Third party Linux drivers are available. Drivers are provided with the ImpactVCB board. Incoming image is digitized using high quality 4:2:2 video sampling and displayed in a window on the PC's screen. The image is transmitted directly by the ImpactVCB into main system memory or the memory of the graphics adapter for high performance results. A Programmers Toolkit is available for the ImpactVCB which provides both DLL and OCX support for applications requiring the ImpactVCB's video capture or video display. Applications can be developed in C or Visual Basic.
