Conferencing in Full HDTV, multi-feed, real-time, medical: the gold standard redefined

For the last few years the International Mastercourse on Endoscopic Sinus Surgery at the Vrije Universiteit Brussel (VUB) has been partially based on live surgery, with extended real-time questions and answers.


Given the extended distance between the operating rooms and conference center in the hospital, a dedicated cabling was needed for the event beforehand. However, this is no longer the case.

NUCLeUS transmitters were added to the operating room cameras, and the video and audio feeds were transmitted in real-time via the hospital intranet to the in-house conference center. The transmission was performed in full HDTV - 1080 image lines - with two video feeds and bilateral audio in real-time. The transmission was based on visual lossless data compression, leading to image quality in the auditorium which was identical to what the surgeons saw on their near-patient monitors. Forget about counting pixels, and looking at compression artifacts… project your imagery on a five-meter wide display, and still enjoy a crystal clear image. The way it should be.

prof. o. michelProf. O. Michel was so pleased that he joked to the audience afterwards: "As we no longer have a pile of cables running through the hallway, I dare to speak of the eSATURNUS wireless revolution". Sure, afterwards he explained to the audience that the video was carried by the hospital intranet. Although a high-end university intranet is known to be well-equipped, it should be stated that not a single dedicated modification had to be made to enable this transmission. The total network load was lower than 10 Mbit, with audio communication sharper and crisper than a telephone connection at zero delay.
