Foresight Imaging Introduces AccuStream Express 170
Frame Grabber & Video Streamer

(Chelmsford, MA - August 7, 2009) Foresight Imaging announces the AccuStream Express 170™ frame grabber and video streamer, a high performance PCI Express x4 board design. The AccuStream Express 170 acquires from DVI, RGB, YPbPr, HDTV, and monochrome video sources up to 170 MHz pixel rates. This includes 1080p HDTV, 1600 x 1200, and other standard and non-standard high resolution video formats. It is specifically designed for the high speed PCIe x4 bus and delivers sustained data transfers of 750 MB per second. This is more than enough to deliver full 1080p HDTV video at 60 frames per second.

Our AccuStream Express 170 is our first of many PCIe designs that produce industry-leading transfer rates. With our 750 MB per second data transfers, we are easily delivering what our customers are demanding: full 1080p video at 60 frames per second," said Tony Molinari, Vice President, Sales & Marketing.
