The need for electronic teaching media to instruct medical students has risen significantly during recent years. This comprises the ability to offer recorded lectures. A current survey (2011/12) conducted at the Medical School of Mainz showed that 93% of students interviewed (n = 131, human and dental medicine) assessed a provision of lecture-records to be important or even very important. Implementation of an automated recording system of lectures faced numerous problems. These include:

- automatic integration of video recordings into the existing learning management system ILKUM
- retrieval of data (date, time stamp, course number, instructor) from Jogustine, a previously established course management system
- recording of lectures by simply entering their course number via remote control
- protection of records against abuse and violation of copyright
- expandability of the system

The technical concept of the system is a dual recording of lectures, employing one permanently installed camera. The camera records the activity of the lecturer, and the computer signal to the projector gets captured as a second stream. Both records will be combined to form a picture in picture video stream being filed on a server. The remaining task of the lecturer is to provide a specific event ID for the recorded lecture. Both the event ID and the auto-generated time stamp allows ILKUM to link the video stream to the appropriate calendar oriented course. Furthermore, ILKUM allows an internal search to identify the individual courses by topic. Unauthorized use is avoided as each access to the video server requires a password. To avoid entering of the password more than once both ILKUM and the video server are connected by a single-sign-on (SSO) network. Due to standardized interfaces (REST interface) the volume of the entire system can be easily expanded. Finally, the learning management system is designed to allow live broadcasts of lectures.
In conclusion, integration of automatically recorded lectures into the ILKUM system considerably improved the quality of electronic teaching media to facilitate medical education.
