Creation of a Neurologic Disease Educational Resource in QuickTime Streaming Format
Find in a Library
Although use of patients in the classroom is valuable in teaching neuroscience, both live and analog videotape demonstrations have inherent limitations. Patient availability may be unreliable, and analog videotape is costly to distribute and incorporate into presentations and examinations. The objective of our project is to create digital source videos depicting neurologic disorders, organize them into a searchable database on an Internet server, and distribute them as a neuroscience resource, free of charge, to health care educational institutions. The specific aims are to (1) create digital video of a neurologist performing the physical examination on patients with neurologic disease, (2) compress this video for Internet delivery in QuickTime streaming format, and (3) organize these video files into a searchable database on an Internet server for file transfer protocol (FTP) download to client institutions. FTP download of streamable files will allow client institutions to organize the files to suit their needs, and distribute them via their own local area network (LAN). This will assure the bandwidth necessary for delivery and uninterrupted playback of this full motion (30 fps) video. Preliminary compressions were done using Sorenson Video variable bitrate option to produce video files deliverable over bandwidths of 30-50 Kilobytes/sec (KBS). Files were formatted as QuickTime HTTP, ‘fast start,’ video which may be distributed from standard LAN servers. Supplemental patient information will accompany video file download. This ‘on-demand’ video resource will reinforce performance-based learning issues in several health care fields.
