What are you talking about? Rugby League has been shown in HD by Sky since the beginning of 2007!!

The RFL are currently experimenting with a new type of ball for next season, it has a chip inside and will work similar to sat nav. It will tell the 4th official exactly where the ball is on the pitch and whether its over the line or not.

It's not the 1st April today.

Slow motion camera's, like the ones used in Cricket, are stupidly expensive and have a very small field of view. You'll notice they only every have them trained on one area at a time (usually the bats man) and will have 2 of them at most at the games.

To do something like that at Rugby would require 100's of them and the director would need to keep changing between them everytime a ball was passed.

Hawkeye is the same thing. Couldn't implement it over a whole rugby pitch with an acceptable accuracy, or even with conversions.

Can it also tell the mood and feelings of the ball carrier?

I liked the camera they used about 10 years ago that followed play down the touchline on a track.

Didn't that get removed because someone crashed into it and got injured?
