In & Out graphics

Video replays are functional if a tournament operates in the "Challenger mode". Video images also generate extra income through advertising. But many times no challengers at all are requested during the play of the set, not very attractive to the tournament organization. TEL can provide realistic graphics of close calls in real time. Experiences in the past have shown that it is very attractive to the audience and media to obtain information on how far a close call was in or out. TEL can provide in & out information in millimeters and show the exact footprint of a bouncing ball. Video line calling cannot provide in & out information in millimeters.
