THE TRIAL of a new vision replay system will kick off on Friday night in the Collingwood-West Coast clash in the first of an 12-match experiment.

Over the final two rounds before finals, the new technology will be available for reviewers to call upon in six games each week.

AFL.com.au believes the clubs involved were told via email on Wednesday.

After the Pies-Eagles clash at the MCG, three of the games on 'Super Saturday' will utilise the alternative vision replay system that allows a decision to be reviewed across multiple camera angles on one screen.

The current score review system replays relevant angles one at a time by the broadcaster.

North Melbourne v Hawthorn at Etihad Stadium, Carlton v Essendon at the MCG and Fremantle v Port Adelaide at Patersons Stadium are the Saturday games taking part in the trial.

On Sunday, the St Kilda-Gold Coast clash at Etihad Stadium and the Greater Western Sydney-Richmond match at Skoda Stadium will finish the round 22 trial.

The AFL is using the system to see if it can improve the accuracy of decisions as well as potentially cut down the time it takes to make them.

It was used in blind trials in round 15.

The round 23 games that will use the new technology are the Sydney Swans v Hawthorn (ANZ Stadium), the Western Bulldogs v Melbourne (Etihad Stadium), St Kilda v Fremantle (Etihad Stadium), Essendon v Richmond (MCG), Collingwood v North Melbourne (MCG) and West Coast v Adelaide (Patersons Stadium).

The other matches in both rounds will use the standard review system.  

In last Saturday's Richmond-Carlton clash at the MCG, a new camera system used in NASCAR racing produced encouraging results when trialled.

It saw goal umpires wear cameras mounted on their heads, which transmitted high definition images back to a video umpire.

Cameras were positioned behind, above and within the goal posts to add more vision to that already available from the broadcasters.

It gave the third umpire the ability to choose the best vision to review while its high definition element allowed for zooming in.

"The results were very encouraging and we'll continue to research all the options available to us," AFL Media executive producer Greg Miles said.
