Wales are using a particular application that allows them to watch a video feed of the match and, as incidents happen (eg scrums, tackles, turnovers, etc) they are able to code for the activity simply by pressing a specific key. At half time and immediately after the match the simple data can be supplied to the coaches, summarising the incidents of the preceding half as raw data.
Additionally, at a later date, the video can be recalled from the database such that, for example, Ryan Jones can see all of his tackles or Gavin Henson can see all of his passes, because as the action is coded live by the video-coaching assistant, each snippet of film is labelled with that code.
Indeed, the whole match can even be watched again and double or triple coded, so that it is not only coded as a line-out, but where it was on the pitch, who threw it in, what part of the line it was thrown to and who won the ball. At the end of a season you could look at all the line-outs you had in the opponents 22 that you threw to the tail and lost...!!!
Very useful.
