Abstract

A system provides for simultaneous collection, storage and analysis of an analog signal and video signal. Multiplexes of up to 240 low bandwidth analog channels with a camera video signal is effective. The output is a standard composite video signal containing analog and video data. The combined signals can be stored on videotape, or can be digitized by a framegrabber. The circuitry separates horizontal synchronizing pulses from a camera output. The signal is then multiplexed with the video signal, such that a portion of each video horizontal line represents the analog data. The combined output is stored together, providing a means for synchronizing the two signals during analysis. The design allows easy coordination of animate and inanimate events with video images from a standard video camera. The system also provides for interleaving digitized physiological signals and video images of subjects onto digital media in a standard file format. The system can provide for multimedia communications such as teleconferencing, surveillance systems using video and analog signals and also single cell physical and visible behavior according to changing conditions.
