Seizure Recording Into Compressed Digital Video Files

Combined hardware/software techniques to record camera video of patient's behavior with contemporaneous physiological signals (EEG, ECG, PSG etc.) onto digital media (optical disk, magnetic disk, D.A.T. etc.) in a PC environment will be developed and tested. The most current techniques for video data compression will be necessary and include two-dimensional intra-frame image compression as well as inter-frame redundancy reduction. A successful result will have many biomedical applications, both research related and clinical. This project will focus on its application to clinical video/EEG monitoring for epilepsy. Direct video/EEG recording to computer disk could replace video tape recording presently used clinically in hundreds of epilepsy centers. Significant time saving to find, analyze, and annotate seizures on video tape would result. Increased precision in correlating behavioral and physiologic data as well as a vast improvement in convenient archiving and networking video/EEG data files would also result.
