In a meeting of the Eurovision Reference Group on 29 June 2011 , it was decided that the televoting system would revert the format used most recently in the 2009 Contest , in which the phone and SMS lines opened for a fifteen-minute window after all songs had been performed , instead of opening before the show starts , which was the system used between 2010 and 2011 . The results format of each show remained the same with each country 's votes being decided on a 50:50 split between televoting and a national jury . Each participating country had their own national jury , which consisted of five professional members of the music industry
