Audio Visual System Architecture
The audio-visual system is a mission-critical component of the center. It needs to record student-standardized patient encounters in exam rooms, team performance in the operating room, emergency room, and ICU, debriefings, and meetings. Audio fidelity is even more important than visual fidelity. It should be possible to hear every word the student and the standardized patient say. It needs to clearly record the audio for team communication, debriefings, and meetings.
Are pan-tilt-zoom cameras necessary everywhere or will fixed cameras do the job? If we use PTZ cameras, who will control them? What is the budget for operators and where do the funds come from? Should the cameras remained fixed to should they follow the student (using an RFID tag or by some other means?
How do we start and stop the recordings and attach a meaningful session identifier to the recorded video?
How do we record the video as well as make it available in real time?
What is the most cost-effective architecture that will meet the needs of the center? What architecture provides the best platform for future expansion?
We will look into network video cameras that stream MPEG4 and support audio. Possible cameras include the Axis 211A (http://www.axis.com/products/cam_211a/index.htm) and the Sony SNC-RZ30N.
