Videocraft has once again provided live OB facilities for the Westmead Hospital Endoscopy Symposium. The annual symposium brings together International and Australian medical practitioners to review the latest technology for endoscopy procedures. For the fourth consecutive year, Videocraft provided an integrated fly away live production solution to deliver the live HD images direct from the operating theatres to the Grand Ballroom at the Hilton Hotel in Sydney.
The system was based around a Blackmagic Design ATEM 4K Production Switcher, with an EVS server and IP Director for recording and instant replay of the procedures taking place in each of the theatres at Westmead. The EVS server also afforded fast delivery of the images to the client drives for editing and archiving purposes.
The Endoscopy Symposium presents a number of challenges, in that the various endoscopes each offer different signal outputs over varying types of connections ranging from VGA, Composite, DVI and HDMI in both NTSC and PAL formats. Videocraft integrated multiple TVOne C2-2855 Scaler/ Scan Convertors to provide high quality signal up-conversion and format conversion. Gary Burns, AV Technical Manager of the Endoscopy Symposium noted “The system provided by Videocraft was very easy to use; the doctors were impressed with the quick replay from the EVS servers when analysing procedures from multiple theatres, without affecting the archive recording of all the scopes during the replay”.
With the normal microwave links unavailable due to access limitations on Sydney’s MLC tower, satellite uplinks were provided by Globecast from the theatres to the Hilton and Videocraft’s utilised a Comrex Telephone hybrid solution for the return audio and comms transmission. Steven Fox, Videocraft System Engineer said “With our normal microwave link workflow unavailable to us, it meant we had to find a new solution for transmitting the audio and comms back to the control room. The Comrex system was easy to setup and provided us with communications between the producers, technical staff and the moderator at the event so we ensured the right feeds were being shown throughout the conference sessions.”
