Extending its line of OEM video-capture cards, Sensoray recently announced the model 817 PCIe (peripheral-component-interconnect-express) frame-grabber card, which captures 16 channels of compressed JPEG or uncompressed bit maps at speeds as high as 480 frames/sec.

Supporting one, four, eight, or 16 PCIe slots, the board allows the user to set independent capture parameters for each channel. An internal 16×4 analog crosspoint-video switch routes any combination of four input channels to external video monitors. Users can turn each of the four video outputs on or off, allowing the outputs of multiple cards to drive one monitor.

The model 817 contains four identical VCPUs (video-capture and -processing units), each of which handles four input-video channels. Each VCPU employs a four-channel video decoder to convert analog video into digital and a DSP to capture digitized video and to handle various processing tasks, such as frame decimation, caption overlay, JPEG compression, and status reporting. Sensoray provides a software-development kit for the module that includes drivers and sample applications for Windows and Linux operating systems. The price for the model 817 starts at $705 (OEM quantities).

I think if If I played Doom2 on this computer I could get 480fps

Frame grabbers are pretty specialized cards for image capture and analysis. (The systems I work with involve frame grabbers to capture images of parts that are being measured to very high accuracy - like down to less than .5 millionths of an inch.)

For what purpose?

For what purpose?

Measuring components, parts, circuit boards, etc. Many industries (electronics, medical, manufacturing, etc.). Some parts use machines that measure by contact (a precision probe trigger) to pick up the geometry of features of a part. The systems I work with use a magnified image (coupled with the coordinates of the stage holding the part) to create the coordinates and size of features. The standard machines have a resolution of .1 micron. The high precision ones have .01 micron resolution. (A human hair is about 100 microns in diameter.)
