Real-time Video Controller

The DATAPixx series is a complete multi-function data and video processing USB peripheral for vision research. In addition to a dual-display video processor, the DATAPixx series includes an array of peripherals which often need to be synchronized to video during and experiment. These include a stereo audio stimulator, a button box port for precise reaction-time measurement, triggers for electrophysiology equipment, and a complete analog I/O subsystem. Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

The DATAPixx video subsystem converts a dual-link DVI digital video input from the host computer (or laptop) into VGA analog video outputs. The VGA outputs feature full 16-bit video DACs for ultimate precision in very low contrast stimuli. A second VGA output head can show the tester a mirror of the primary display; or alternatively, the left/right halves of a wide DVI input image can be split onto the two VGA displays, ensuring perfect frame synchronization between the left/right displays. To further support stereo applications, the DATAPixx also includes a standard VESA mini-DIN-3 connector for interfacing with stereo glasses.
