Not only do they broadcast the game, but also what I believe to be the official game commentary - for all big titles there is a professional Go player that comments the game for the public in real time.
I am reproducing those variations in the sgf file, but with my conclusions - I cannot read Japanese to know the pro commenter's conclusions. Many of the diagrams are self explanatory though.]RE[W+Resign]
