The ImpactVCB-e is a PCI Express video capture board. Compatible with Windows 10, 8, 7 (both 64-bit and 32-bit), ImpactVCB-e is a low profile board which is supplied with both a full height and half height brackets. All ImpactVCB-e model supports both PAL and NTSC compatibility (referred to as "dual crystal").
Video from any analog 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 standard 4-pin DIN connectors. The PCI based ImpactVCB boards come with a VFW capture driver (Video for Windows) for Windows 95 and Windows NT and a WDM driver for use with WindowsXP, Windows98SE, 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 analog video signal and the resizing of the video image is performed by hardware on the ImpactVCB, thereby not slowing down the CPU. After video is digitized and resized, the digitized video image is drawn by the ImpactVCB directly into the memory of the PC's VGA card. This uses a feature of Windows called Direct Draw and the ImpactVCB can be used with most VGA cards which support Direct Draw 5 or higher. This technique is used on Windows95, Windows98, WindowsME, Windows2000 and WindowsNT 4.0
Some ImpactVCB models have a unique serial number burnt into an EProm on board. The serial number is read either through the Hauppauge WinTV Programmers Toolkit or can be read via Windows Control Panel. In addition to the serial number, these models of ImpactVCB have its I/O configuration burnt into the EProm.
