I've published a specific analysis on the matter, but it's only in Italian.
However numbers are international !!!
You find it here: http://tifosobilanciato.it/2012/03/21/i-nuovi-criteri-di-ripartizione-dei-diritti-tv-in-serie-a/
At pages 4-6 you can find the detail on how the resources are distributed, both with numbers and graphs.
Page 10 makes a simulation on how the 2012/2013 amount increase would have affected the current Serie A structure.
Have a good day.
