Abstract

A new video-synchronized multi-channel data acquisition system has been developed for frequency-domain muscle fatigue research. The system records storage-intensive video images onto a video tape, and simultaneously acquires biomedical data and video time codes onto a computer hard disk to achieve high-speed recording a long duration. A video time-code-bridge-file was created by the computer to synchronize the biomedical data with the recorded video frames in realtime. The two-column time-code-bridge-file matches each video frame-start with the corresponding index number of the acquired data. With the bridge file, the system is able to automatically search and output a frame of the acquired multi-channel data correspondent to a given video frame, and also able to search and display a video frame correspondent to a given frame of acquired multi-channel data. Currently, this system is capable of recording 30 minutes of video-synchronized multi-channel biological data with the summed data rate of 2.16 Mbit/sec and synchronization accuracy of 0.22 mS.
