Disclosed are a method and an apparatus for enabling determination whether a football, during play of an Australian Rules football game, has touched a goal or behind post. The 5 apparatus includes a sound detector in association with the post so that sound produced by substantially any impact or significant momentary contact of the football with the post during play of the football game will be registered by the sound detector, and a storage means to receive signals generated by or in response to operation of the sound detector and to store them as sound data signals. Video apparatus captures and stores video images of the football 10 game during play of the game including images of the football in motion (including in flight, and bouncing or rolling along the ground, and being carried by a player participating in the game) during play of the football game, and display means is operative to display for viewing by an observer the video images from a time period in the game which included an incident of interest involving the football being in proximity to the post. Sound manifesting means (e.g. a 15 speaker and / or video display) manifests the sound information embodied in the sound data signals in close synchronism with the display of video images by the display whereby the observer can compare the synchronicity and the characteristics of sound information manifested with the images of the football presented by the display means including images of the football when in closest proximity to the post, thereby enabling determination if the 20 football touched the post during play of the football game. |
