[section deleted] END OF HOMOLOGATION FORM It is important to leave the above section in the exact format as it will be processed automatically. The following section is where free form comments are added and attachments are made. HOMOLOGATOR'S REMARKS Give details of any variations of IWSF rules. List any alterations to the course, etc. during the competition. List any malfunction of equipment. Give any further information which might affect the Tournament Council's assement of the homologation. Tricks judged from handheld boat video camera, wireless feed to 20" TV's in judging area. Fixed camera utilized "wing mirrors", which presents extended views of areas outside the wake to the right and left sides, at the top and bottom of the video display, used as backup. Trick Records set -- Preliminary Round -- Whitnew McClintock, 7070, Canadian Girls Record Final Round -- Adam Pickos, 7600, AWSA Boys 2 Record. Wireless Video Transmission used extensively for all events. Slalom boat path camera image transmitted wirelessly to judging area for monitoring and recording. Boat cameras (two) in tricks both transmitted wirelessly to judging area. One handheld camera used as primary for judging, with fixed view camera used for backup for both judging and timing. Both jump measurement camera images were also transmitted wirelessly. Altogether, used five wireless cameras -- one for slalom, two for tricks, and two for Jumping. Used channels 1 & 2 for Tricks, and 3 & 4 for jumping, and put slalom end-course on channel 1 (kept jump camera #1 off during Slalom event). Wireless equipment worked flawlessly all day Saturday (Preliminary round). Sunday partway through the Slalom event we began to notice some source of interference with the received wireless video images, when setting up the Jump Cameras. Created some occasional blips in the trick images, but did not result in any lost frames and hence did not interfere with the Trick timing integrity. Frame selection during jump disclosed that the nature of the interference was clobbering only one or two adjacent frames, but the frames on either sides were OK, and so were always able to find a clear landing image to measure. Guessing this may have been a wireless ethernet or some other digital signal source, rather than a cordless phone or baby monitor or microware oven which have previously been found as sources of interference. Never did pin this down or eliminate it. But after living through this for the day we learned that this did not cause insurmountable problems to video-based measurement and timing.
