[Teleteaching in Otorhinolaryngology (part 1).Real-time transmission of a congress in picture and tone into the Internet].

Abstract:

:The transmission of scientific seminars into the Internet represents a new application of modern technologies for teleteaching.We digitally recorded 74 seminars and discussions during the 8th annual meeting of the German Society of Skull Base Surgery with five cameras and eight microphones, and transformed the data live with the real-Producer using a video card.This transferred data stream was sent via ISDN (128 kbit/s) to a real-server at the university, which was used for distribution in the net.The seminars could be called up in the display format of 320×240 pixels with a delay of 3 min (minimum: 30 s, as a function of the connection of the user) at each computer with Internet entrance. Altogether,we registered 3,284 accesses to the presentations following the congress until June 2002. The quality of picture transmission (24-36 kbit/s) and the quality of tone (audio stream: 5 kbit/s) were sufficient to understand the contents of the slide, video or computer presentation.The transmission of scientific meetings into the Internet can increase, with a justifiable technical expenditure, their efficiency by the ubiquitous availability of the information and the extension of the audience.
