Sports Video Analysis or “Tagging” is a way of marking events in a videoed sports activity. Examples of events might be line-outs, scrums, goals, fouls, red or yellow cards, tennis serves, volleys, in fact any event in any sport.
Events are recorded in a timeline showing the exact points in the match video the events happened, the timeline also shows how long each event lasted.
An example of this might be volleys that happen in a 슈어맨 tennis match. The analyst would be able to see how long the volleys lasted and generate reports as to which player won most of the volleys. This information could be used to ascertain the strength or weakness of each player’s volley skills, and over time map improvements due to training etc.
Events are tagged using a code window. When an event happens in a match the analyst clicks a button in the code window that represents the event. If a “home line-out” happens in a rugby match the analyst would click a “home line-out” button in the code window.
The code window event button may have other buttons associated to it that describe the event in more detail, in rugby this might be “home line-out -> Catch & drive” or “home line-out -> Off top”. In some software used to analyse matches the “Home line-out” would be an “Action” and the associated “Catch & drive” or “Off top” would be “Tags”. This terminology varies but the idea is the same. This prevents mistakes being made like “Red card -> Catch & drive” – in rugby this doesn’t make sense.
