Hauppauge, New York-based Hauppauge Computer Works Inc has several new video overlay and video capture board products in its Win/TV product family. Win/TV Studio is a high-end, high-resolution board for production-quality applications, capable of capturing video at 60 frames per second. Win/TV Pro is a video capture board with Motion JPEG compression and a suite of software. Win/TV Star is a low-cost video capture board with a Motion JPEG module. Win/TV HighQ is an application-specific video capture and playback board intended for information kiosks. Win/TV Theater is a high-end desktop editing product. The new features these products introduce include Motion JPEG compression, resolution to 1,280 by 1,024 pixels, S-Video inputs and 4:2:2 colour operation. All Win/TV video capture boards (except the Win/TV HighQ) feature built-in cable-ready 122-channel TV tuners with stereo audio, the company says. Motion JPEG compression is based on the C-Cube Microsystems Inc CL550 chip and supports full-motion capture of broadcast-quality video images to hard disk for non-linear editing. These new Win/TV boards capture still video images in 4:2:2 colour format, for twice as much colour information per picture as the 4:1:1 format of most video capture boards. This eliminates the moire patterns and other artifacts that are common on lower-quality captured video images. Win/TV shows standard video inside a moveable, resisable VGA display window in the Microsoft Corp Windows graphical environment; versions are also available for MS-DOS and for OS/2. It intercepts the connection between a computer’s VGA board and its monitor, and inserts its video image there, in its designated window position, with real-time motion. This pass-through connection eliminates the problem of limited computer system bus and memory speeds, which are too slow to display full-motion images in real time. The Win/TV board communicates with its companion software to determine the size and position of the on-screen window, and whether the image that will occupy it should be the full-screen video or a zoomed-in image of a selected area. For applications involving multiple video inputs, six of the Win/TV boards can coexist in a system. Minimum requirements are Windows 3.0, a VGA adaptor and monitor, and an available 16-bit AT bus slot. The Win/TV board will ship during the first quarter of next year, at a price of up to $1,300.
