title: A data acquisition system for long-term monitoring of physiological and video signals.
abstract: We developed a system for interleaving digitized physiological signals and video images of subjects onto digital media in a standard file format. The system consists of a framegrabber used to digitize video signals, a microcomputer used to digitize analog signals and send the resulting signals over a parallel interface, and a host laboratory computer to gather and store the video and analog data in an interleaved format as a single file. The system allows for digital storage, search and display of video signals concurrently with physiological signals.
