When Jake Ireland is looking at the replay during a challenge I suggest that TSN shows the replay he is looking at, in real time, so the at home fans can see what he bases his decision on. Once he makes his decision this live replay feed from Jake would be turned off. The referee on the field would then announce the decision just like he does now.
We already get the ability to look at the play live with the officials on the field. This would be an extension of that.
